RESUMO

BACKGROUND: Emergence delirium remains a major postoperative concern for children undergoing surgery. Nalbuphine is a synthetic mixed agonist-antagonist opioid, which is believed to reduce the incidence of emergence delirium in children. The primary objective was to examine the effect of nalbuphine on emergence delirium in children undergoing surgery. METHODS: Databases of MEDLINE, EMBASE, and CENTRAL were searched from their starting dates until April 2023. Randomized Clinical Trials (RCT) and observational studies comparing nalbuphine and control in children undergoing surgery were included. RESULTS: Eight studies (n = 1466 patients) were eligible for inclusion of data analysis. Compared to the control, our pooled data showed that the nalbuphine group was associated with lower incidence of emergence delirium (RR = 0.38, 95% CI [0.30, 0.47], p < 0.001) and reduced postoperative pain scores (MD = -0.98, 95% CI [-1.92, -0.04], p = 0.04). CONCLUSIONS: This review showed the administration of nalbuphine is associated with significant decrease in the incidence of emergence delirium and postoperative pain scores among children undergoing surgery. However, due to limited sample size, high degree of heterogeneity and low level of evidence, future adequately powered trials are warranted to explore the efficacy of nalbuphine on emergence delirium among the pediatric population.

RESUMO

RESUMEN Objetivo: Describir la cronología, evolución e impacto de la investigación global sobre el dolor crónico posoperatorio. Materiales y métodos: Estudio bibliométrico que utilizó la base de datos Scopus. Se diseñó y validó una búsqueda estructurada que permitió la recolección de metadatos, los cuales se analizaron a través del paquete Bibliometrix del lenguaje de programación R. Se realizó la descripción de las características generales, la evolución y el cálculo de métricas de impacto de la investigación global sobre el dolor crónico postoperatorio. Resultados: Se incluyeron 1496 documentos, con una ventana de tiempo entre 1983 y 2023. El 70,7 % (n = 1059) de la producción total fueron artículos originales, seguido de revisiones (n = 357; 23,8 %). Existió una colaboración internacional del 15,6 %, y, desde 1983, ha existido un crecimiento sostenido de la producción, con un incremento marcado en los últimos 13 años, donde el 2022 fue el año más fecundo (n = 191 documentos publicados). Se identificó que Canadá y Dinamarca lideran el impacto de la investigación global, y cuentan con los autores e instituciones más prolíficas. Sin embargo, Estados Unidos es el país más productivo, ya que lidera una importante colaboración, esencialmente junto a países europeos y latinos. Se encontró que el dolor neuropático, la valoración de factores de riesgo y el manejo del dolor son algunos de los tópicos más frecuentes. En los últimos 10 años, aproximadamente, ha existido un interés persistente en la investigación sobre calidad de vida, predicción, prevención y valoración de factores de riesgo. Últimamente, ha existido especial interés en el estudio del dolor en cirugía toracoscópica videoasistida y construcción de modelos de predicción. Conclusiones: Se reveló un crecimiento sostenido en la investigación global sobre dolor crónico postoperatorio, en los últimos 40 años. Dicho crecimiento ha estado liderado esencialmente por instituciones canadienses y danesas, a pesar de que se ha considerado a Estados Unidos como el país más prolífico. Asimismo, ha existido una transición importante en los tópicos estudiados, se ha pasado del uso de fármacos y determinación de factores de riesgo al estudio de modelos de predicción, sistematización de datos y cirugía videoasistida.

ABSTRACT Objective: To describe the chronology, evolution and impact of global research into chronic postoperative pain. Materials and methods: A bibliometric study was conducted using the Scopus database. A structured search was designed and validated, thereby allowing the collection of metadata, which were analyzed through the Bibliometrix package of the R programming language. The study involved the description of the general characteristics, evolution and calculation of impact metrics of global research into chronic postoperative pain. Results: The study included 1,496 documents, which spanned from 1983 to 2023. Original articles accounted for 70.7 % (n =1,059) of the total output, followed by reviews (n = 357; 23.8 %). There was an international collaboration rate of 15.6 %, and there has been sustained growth in output since 1983, with a sharp increase in the last 13 years, 2022 being the most prolific one (n =191 published documents). It was identified that Canada and Denmark lead the impact of global research and have the most productive authors and institutions. However, the United States is the most prolific country because it leads significant collaboration, mainly with European and Latin American countries. Neuropathic pain, risk factor assessment and pain management were identified as some of the most frequent topics. Over the past approximately 10 years, there has been persistent interest in research on quality of life, prediction, prevention, and risk factor assessment. Recently, there has been interest in studying pain in video-assisted thoracoscopic surgery and developing predictive models. Conclusions: The study revealed sustained growth in global research on chronic postoperative pain over the past 40 years. Such growth has been mainly led by Canadian and Danish institutions, despite the United States being the most prolific country. Moreover, there has been a significant transition in the studied topics, moving from the use of drugs and identification of risk factors to the study of predictive models, data systematization, and video-assisted surgery.

RESUMO

Fundamento el dolor postoperatorio se considera un dolor con limitaciones de tiempo, a menudo mal controlado. Su manejo representa un gran desafío, ya que la analgesia postoperatoria debe brindar a la madre un control adecuado de este, y a su vez facilitar la atención del bebé. Objetivo evaluar la efectividad de la anestesia subaracnoidea con morfina como tratamiento del dolor postoperatorio en cesárea. Métodos estudio descriptivo y transversal, realizado en el Hospital General Docente Martín Chang Puga, del municipio de Nuevitas, provincia de Camagüey, entre enero de 2021 y diciembre de 2022. La muestra estuvo conformada por 36 pacientes a las cuales se aplicó anestesia subaracnoidea con lidocaína hiperbárica más morfina para la cesárea. Resultados predominó la edad comprendida entre 27-31 años. El 63,9 % de las cesareadas no refirió dolor postoperatorio. Casi la mitad de la población (47,2 %) estudiada presentó efectos secundarios con el uso de la morfina intratecal, principalmente el prurito. El 80,5 % expresó satisfacción con la analgesia postoperatoria. Conclusiones la mayoría de las pacientes encontraron satisfacción con el tratamiento analgésico, a pesar la presencia de efectos adversos, de modo que el uso de morfina intratecal es efectivo en el manejo del dolor poscesárea.

Foundation Postoperative pain is considered time-limited pain, often poorly controlled. Its management represents a great challenge, since postoperative analgesia must provide the mother with adequate control, and at the same time facilitate care for the baby. Objective to evaluate the effectiveness of subarachnoid anesthesia with morphine as a treatment for postoperative pain in cesarean section. Methods descriptive and cross-sectional study carried out at the Martín Chang Puga General Teaching Hospital, in the Nuevitas municipality, Camagüey province, between January 2021 and December 2022. 36 patients to whom subarachnoid anesthesia was applied with Hyperbaric lidocaine plus morphine for cesarean section were considered as the sample. Results the age between 27-31 years predominated. 63.9% of cesarean patients did not report postoperative pain. Almost half of the population (47.2%) studied presented side effects with the use of intrathecal morphine, mainly pruritus. 80.5% expressed satisfaction with postoperative analgesia. Conclusions the majority of patients were satisfied with the analgesic treatment, despite the presence of adverse effects, so that the use of intrathecal morphine is effective in the management of post-cesarean section pain.

RESUMO

Timely post-operative pain management in elderly patients is critically important. Given their physiological changes and comorbidities, management in this group of patients is different from the rest of the population. Knowledge of potentially inappropriate medications (Beers criteria) is relevant because of the presence of comorbidities in this population. Although acetaminophen continues to be safe, non-steroidal anti-inflammatory agents produce several adverse effects which need to be considered before they are used. On the other hand, opioids continue to be one of the pillars in analgesia, with due consideration of their adverse affects and interactions, and the need for dose adjustments. Adequate postoperative pain management prevents adverse effects and the risk of developing chronic pain.

El manejo oportuno del dolor en la población anciana durante el periodo posoperatorio es de vital importancia. Este grupo de pacientes, dado sus cambios fisiológicos y comorbilidades, requieren un manejo diferente al resto de la población. Es relevante conocer cuáles medicamentos son potencialmente inapropiados para su uso (criterios de Beers) ante las comorbilidades de esta población. Si bien el acetaminofén continúa siendo seguro, los antiinflamatorios no esteroideos causan varios efectos adversos que ameritan consideración antes de su uso; por su parte, los opioides siguen siendo uno de los pilares analgésicos, teniendo en cuenta sus efectos adversos y valorando la necesidad de ajuste de dosis e interacciones. El adecuado manejo del dolor posoperatorio previene desenlaces adversos y el riesgo de cronificación.

RESUMO

Apesar da evolução da tecnologia minimamente invasiva com procedimentos cirúrgicos extremamente seguros, são recorrentes no período pós-operatório complicações como dor, náusea, vômito, cefaleia, sonolência e depressão respiratória, sendo estes os principais motivos de internações hospitalares prolongadas.

RESUMO

Third molar extraction surgery is a frequentprocedure in dentistry. Like any surgical procedure, it may lead to inflammatory responses, and postoperative pain is one of its main complications. Furthermore, temporomandibular disorder (TMD) is a collective termfor several clinicalproblems involving orofacial structures. Patients withparafunction are more sensitive to mechanical stimuli such as pressure during surgical procedures. Aim: To analyze postoperative pain in patients with and without bruxism subjected to third molar extraction surgery. Materials and Method: This was an observational study including four groups with a 1:1:1:! allocation ratio, conducted following ethical approval. Patients classified as ASA I with an indication for lower third molar extraction were recruited. Bruxism was self-reported. Two surgical techniques were used: one with only forceps and levers (ST1) and another with osteotomy and odontosection (ST2). Results: Four groups (bruxism and surgical techniques) were enrolled, each with a convenience sample (n=34). Postoperative pain levels were higher in patients with than without bruxism (p<0.05). The comparison between surgical techniques showed significantly higher pain levels only on the seventh day for ST2 groups (p<0.05). Oral mucosaflap incisions did not cause significantly higher persistence and pain levels. Conclusions: Bruxism, osteotomy, and odontosection may have increased postoperative pain levels, whereas performing an oral mucosa flap did not cause significant differences. Nevertheless, these preliminary data should be interpreted carefully. Randomized controlled trials are required to reinforce the findings of this study.

A cirurgia de extragao de terceiros molares é um procedimento frequente na odontologia. Como em qualquer procedimento cirúrgico, pode levar a respostas inflamatorias. A dor pós-operatória é uma das principais complicagoes após a cirurgia de extragao de terceiros molares. Além disso, disfungao temporomandibular (DTM) é um termo coletivo para vários problemas clínicos envolvendo estruturas orofaciais. Pacientes com parafungao sao mais sensíveis a estímulos mecánicos como pressao durante procedimentos cirúrgicos. Objetivo: Analisar a dor pós-operatória em pacientes com e sem bruxismo submetidos á cirurgia de extragao de terceiros molares. Material e Método: Um estudo observacional incluindo quatro grupos com uma proporgao de alocagao de 1:1:1:1 foi realizado após aprovagao ética. Foram recrutados pacientes classificados como ASA I com indicagao de exodontia de terceiros molares inferiores. O bruxismo foi autorreferido e foram realizadas duas técnicas cirúrgicas: uma com apenas fórceps e alavancas (ST1) e outra com osteotomia e odontosecgao (ST2). Resultados: Foram incluidos quatro grupos (bruxismo e técnicas cirúrgicas), cada um com uma amostra de conveniencia (n=34). Os níveis de dor pós-operatória foram maiores em pacientes com bruxismo (p<0,05). A comparagao entre as técnicas cirúrgicas mostrou níveis de dor significativamente maiores apenas no sétimo diapara os grupos ST2 (p<0,05). Incisoes de retalhos de mucosa oral nao mostraram níveis de dor significativamente maiores. Conclusoes: Bruxismo, osteotomia e odontosecgaopodem aumentar os níveis de dor pós-operatória, enquanto a realizagao de retalho de mucosa oral nao apresenta diferengas significativas. No entanto, a interpretagao cuidadosa desses dados preliminares é recomendada, e ensaios clínicos randomizados sao necessários para fortalecer os achados deste estudo.

RESUMO

This systematic review and network meta-analysis aimed to answer the following focused research question: "Does the type of endodontic sealer affect the postoperative pain in patients who received endodontic treatment?" Different databases and grey literature were surveyed. Only one randomized controlled trial were included. The risk of bias in the studies was evaluated by using the Cochrane Collaboration's tool. A random-effects meta-analysis was conducted to compare the risk and intensity of postoperative pain. The quality of the body of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation approach. Out of 11,601 studies, 15 remained for qualitative analyses and 12 for meta-analysis. Seven studies were classified at high risk of bias, and 8 studies raised some concerns. No significant differences between the endodontic materials were observed in the direct comparisons, both in risk and in intensity of postoperative pain (pairwise comparisons with 2 studies: I2 = 0%; p > 0.05 and 8 studies: I2 = 23%; p > 0.05, respectively). The certainty of the evidence was graded as low or moderate. There was no difference in the risk and intensity of postoperative pain after filling with different endodontic sealers. Further systematic reviews should be conducted. Trial Registration: PROSPERO Identifier: CRD42020215314.

RESUMO

Avaliar e manejar a dor no período pós-operatório é fundamental, pois a dor aguda, se não ratada, é capaz de alterar diversos sistemas orgânicos. A realidade virtual constitui instrumento promissor de baixo custo para o alívio da dor. Este trabalho objetivou determinar a eficácia da realidade virtual no manejo da dor aguda leve a moderada em pacientes no pós-operatório mediato. Trata-se de um estudo clínico randomizado, realizado em um hospital pediátrico de Curitiba. Os participantes da pesquisa foram randomizados e alocados em dois grupos, submetidos a um vídeo temático relaxante e à realidade virtual. Os dados foram submetidos à análise estatística descritiva e inferencial. A redução da dor proporcionada pela realidade virtual é estatisticamente significativa e superior quando comparada à redução induzida pelo vídeo temático relaxante, podendo otimizar a experiência de hospitalização, com atenção centrada na experiência do paciente, mitigando os efeitos colaterais relacionados ao uso de opioides.

Assessing and managing pain in the post-operative period is essential, as acute pain, if left untreated, can alter several organic systems. Virtual reality is a promising low-cost tool for pain relief. This study aimed to determine the effectiveness of virtual reality in the management of mild to moderate acute pain in patients in the immediate postoperative period. This is a randomized clinical study, carried out in a pediatric hospital in Curitiba. Research participants were randomized and allocated into two groups, and shown a relaxing thematic video and virtual reality. Data were subjected to descriptive and inferential statistical analysis. Pain reduction provided by virtual reality is statistically significant and superior when compared to the reduction induced by the relaxing thematic video, and can optimize the hospitalization experience, with attention focused on the patient's experience, mitigating side effects related to the use of opioids

RESUMO

BACKGROUND: This randomized trial compared pericapsular nerve group block and periarticular local anesthetic infiltration in patients undergoing primary total hip arthroplasty. We hypothesized that, compared with pericapsular nerve group block, periarticular local anesthetic infiltration would decrease the postoperative incidence of quadriceps weakness at 3 hours fivefold (ie, from 45% to 9%). METHODS: Sixty patients undergoing primary total hip arthroplasty under spinal anesthesia were randomly allocated to receive a pericapsular nerve group block (n=30) using 20 mL of adrenalized bupivacaine 0.50%, or periarticular local anesthetic infiltration (n=30) using 60 mL of adrenalized bupivacaine 0.25%. Both groups also received 30 mg of ketorolac, either intravenously (pericapsular nerve group block) or periarticularly (periarticular local anesthetic infiltration), as well as 4 mg of intravenous dexamethasone.Postoperatively, a blinded evaluator carried out sensory assessment and motor assessment (knee extension and hip adduction) at 3, 6 and 24 hours. Furthermore, the blinded observer also recorded static and dynamic pain scores at 3, 6, 12, 18, 24, 36 and 48 hours; time to first opioid request; cumulative breakthrough morphine consumption at 24 hours and 48 hours; opioid-related side effects; ability to perform physiotherapy at 6, 24 and 48 hours; as well as length of stay. RESULTS: There were no differences in quadriceps weakness at 3 hours between pericapsular nerve group block and periarticular local anesthetic infiltration (20% vs 33%; p=0.469). Furthermore, no intergroup differences were found in terms of sensory block or motor block at other time intervals; time to first opioid request; cumulative breakthrough morphine consumption; opioid-related side effects; ability to perform physiotherapy; and length of stay. Compared with pericapsular nerve group block, periarticular local anesthetic infiltration resulted in lower static pain scores (at all measurement intervals) and dynamic pain scores (at 3 and 6 hours). CONCLUSION: For primary total hip arthroplasty, pericapsular nerve group block and periarticular local anesthetic infiltration result in comparable rates of quadriceps weakness. However, periarticular local anesthetic infiltration is associated with lower static pain scores (especially during the first 24 hours) and dynamic pain scores (first 6 hours). Further investigation is required to determine the optimal technique and local anesthetic admixture for periarticular local anesthetic infiltration. TRIAL REGISTRATION NUMBER: NCT05087862.

RESUMO

BACKGROUND: Laparoscopy revolutionizing digital and robotic technology for surgical practice. The ability of anesthetic agents and neuronal blockade to modify the response to surgical trauma has been widely studied in the last few years. OBJECTIVES: evaluate if Anterior Quadratus Lumborum Block contributes to attenuate surgical repercussions, having as primary parameters analgesia and secondary the pulmonary function and neuroendocrine response to trauma. METHODS: prospective, controlled, Double-blind study, in which 51 patients scheduled for eletive laparoscopic cholecystectomy were randomly selected and distributed into 2 groups. Control group received general anesthesia, and the intervention group was submitted to general anesthesia plus Anterior Quadratus Lumborum Block. The parameters evaluated were: postoperative pain, respiratory muscle pressure, and inflammatory response to surgical stress with the plasma dosage of Interleukin 6, C-Reactive protein and cortisol. The following situations were excluded: refusal to participate in the study; body mass index greater than or equal to 40, peripheral neuropathies, coagulopathies or hypersensitivity to drugs used; infection at the puncture site; fever, purities; dementia or other states that would prevent the adequate understanding of the use of the numeric-verbal scale of pain; immunological diseases, diabetes, malignant neoplasia, use of opioids or anti-inflammatory drugs in the preoperative period; antidepressants and anticonvulsants, conversion open surgery, re-exploration and hospital stay. RESULTS: Slowed Interleukin 6 cytokine production and decrease in cortisol release, accompanied by significant attenuation of surgical repercussion on lung function and significant reduction in postoperative pain scores and consumption of pain medication. CONCLUSION: An important strategy for analgesia in abdominal laparoscopic surgery.

RESUMO

BACKGROUND: This study evaluated the efficacy of epidurally administered magnesium associated with local anesthetics on postoperative pain control. METHODS: The study protocol was registered in PROSPERO as CRD42021231910. Literature searches were conducted on Medline, Cochrane, EMBASE, CENTRAL, and Web of Science for randomized controlled trials comparing epidural administration of magnesium added to local anesthetics for postoperative pain in elective surgical adult patients. Primary outcomes were the time to the first Postoperative (PO) Analgesic Request (TFAR), 24-hour postoperative opioid consumption, and Visual Analog Scale (VAS) scores at the first six and 24 postoperative hours. Secondary outcomes included Postoperative Nausea and Vomiting (PONV), pruritus, and shivering. Quality of evidence was assessed using GRADE criteria. RESULTS: Seventeen studies comparing epidural were included. Effect estimates are described as weighted Mean Differences (MD) and 95% Confidence Intervals (95% CI) for the main outcomes: TFAR (MD = 72.4 min; 95% CI = 10.22-134.58 min; p < 0.001; I2 = 99.8%; GRADE: very low); opioid consumption (MD = -7.2 mg (95% CI = -9.30 - -5.09; p < 0.001; I2 = 98%; GRADE: very low). VAS pain scores within the first six PO hours (VAS) (MD = -1.01 cm; 95% CI = -1.40-0.64 cm; p < 0.001; I2 = 88%; GRADE: very low), at 24 hours (MD = -0.56 cm; 95% CI = -1.14-0.01 cm; p = 0.05; I2 = 97%; GRADE: very low). CONCLUSIONS: Magnesium sulfate delayed TFAR and decreased 24-hour opioid consumption and early postoperative pain intensity. However, imprecision and inconsistency pervaded meta-analyses, causing very low certainty of effect estimates.

RESUMO

Objective: Determine the effectiveness of the piezoelectric handpiece vs. the straight handpiece at low speed in surgeries of impacted lower third molars, in relation to post-surgical effects (edema, pain and trismus) and the operative time of the osteotomy, in patients attending the Maxillofacial Surgery Service of the "Hospital de Especialidades Fuerzas Armadas N°1". Method: It is an observational, analytical, longitudinal prospective cohort clinical study. A sample of 40 patients of both sexes aged between 18 and 25 years was taken, divided into two groups of 20 patients each, in group A extractions were performed with piezoelectric and in group B with straight rotary handpiece at low velocity. The results were analyzed on the third, fifth and eighth day, the edema was measured with the method of Amin and Laskin, for the pain the Visual Analogous Scale (VAS) was used, and for the presence of trismus with the instrument foot of king. Results: In group A, edema (11.72 mm), pain (4.67) and mouth opening (39.49 mm) were lower than in group B edema (12.29 mm), pain (4.8) and mouth opening (35.83 mm) and osteotomy time was significantly longer with piezoelectric (6.54 ± 3.05 min) compared to the straight handpiece (1.55 ± 0.57 mm). min) and there was a difference in edema, pain and trismus under normal conditions in contrast to what was obtained at 3, 5, 8 days between the two instruments. Conclusion: the post-surgical effects of edema, pain and trismus of the extraction of retained lower third molars are less intense with the piezoelectric compared to the straight handpiece, the use of the piezoelectric being recommended.

RESUMO

Aim: to evaluate the clinical efficacy of an acetaminophen analgesic by comparing its prescription in fixed versus ondemand schedules after periodontal surgery. The hypothesis of the study was that the fixed regimen would be more effective than the on-demand regimen for postoperative analgesics following periodontal surgery. Methods: An open randomized clinical trial was conducted. The 68 patients who needed total flap surgery to restore supracrestal tissue attachment or surgical treatment of periodontitis were randomized". Visual Analogue Scale was used to assess pain. The fixed group (n = 34) received 500 mg of acetaminophen every 4 hours for 2 days. The on-demand group (n = 34) was instructed to use the acetaminophen "as needed," at intervals of no less than 4 hours between doses. Ibuprofen was the rescue medication for both groups. Pain scores and medication use were recorded 2, 6, 12, 24 and 48 hours after the surgical procedure. The study was registered at the Brazilian Registry of Clinical Trials under RBR-7wv259. Results: The two groups did not differ in relation to the frequency or the intensity of pain in a 48-hour period (n=20 in the fixed group, and n=22 in the on-demand group), or even in the intention-to-treat (n=34 in each group). Individuals who experienced moderate to severe pain used rescue medication more frequently in both groups. No adverse events were reported. Conclusion: Both regimens were effective in controlling postoperative pain after periodontal surgery

RESUMO

Abstract The purpose of this study was to compare the outcomes of a modified gingival graft technique, in which the released flap is positioned and sutured over the graft, with the conventional free gingival graft (FGG) procedure, when both are used for gingival augmentation. A 12-month, multicenter parallel randomized controlled trial was conducted. Subjects with buccal RT2 gingival recessions and keratinized tissue width (KTW) < 2 mm in at least one mandibular incisor were randomized to control group (n = 20; conventional FGG) or test group (n = 20; modified FGG; flap sutured over FGG using sling sutures). The primary outcome (KTW) was measured at baseline and after 3, 6 and 12 months, as was keratinized tissue thickness (KTT). Postoperative pain (POP) and analgesic intake were also recorded. Both techniques promoted a significant increase in KTW and KTT when compared to baseline (p < 0.05) with no significant differences between groups (KTW change of 6.1±1.5 mm and 5.4±1.6 mm, for control and test, respectively; p=0.16). However, test group patients reported less POP after 7 days and used less analgesic medication than control group patients (p < 0.05). We concluded that the modified FGG was comparable to conventional FGG in augmenting keratinized tissue width and thickness at mandibular incisors, but resulted in less patient morbidity.

RESUMO

ABSTRACT Objective: To evaluate the influence of intertransverse septal anesthetic block (BASIT) on postoperative pain in lumbar spine surgery. Methods: The study was carried out prospectively and observationally. Were included 105 patients who underwent posterior lumbar spine surgery, divided into two groups: 35 patients in the experimental group, who received BASIT at the end of the procedure, and 70 patients in the control group, without BASIT. Patients were assessed for low back pain (visual pain scale), opioid consumption on the 1st postoperative day, complications related to the procedure, and length of stay after surgery. Results: The sample consisted of 46 men and 59 women, with a mean age of 57.7 years (21 to 90 years). Mean postoperative pain in the experimental group was 1.88, and in the control group 2.11 (p<0.05). There was a trend towards less morphine use in the experimental group with p = 0.053. There was a statistical difference in morphine consumption between patients who did not previously use opioids and those who already used them (p 0.04). There was no difference between the groups regarding length of stay. Conclusion: Anesthetic blockade of the intertransverse septum reduced the consumption of opioids and the levels of low back pain after surgery (p<0.05), with no statistical difference in length of hospital stay or complications related to the technique. Level of Evidence II; Clinical Prospective Study.

Methods The study protocol was registered in PROSPERO as CRD42021231910. Literature searches were conducted on Medline, Cochrane, EMBASE, CENTRAL, and Web of Science for randomized controlled trials comparing epidural administration of magnesium added to local anesthetics for postoperative pain in elective surgical adult patients. Primary outcomes were the time to the first Postoperative (PO) Analgesic Request (TFAR), 24-hour postoperative opioid consumption, and Visual Analog Scale (VAS) scores at the first six and 24 postoperative hours. Secondary outcomes included Postoperative Nausea and Vomiting (PONV), pruritus, and shivering. Quality of evidence was assessed using GRADE criteria. Results Seventeen studies comparing epidural were included. Effect estimates are described as weighted Mean Differences (MD) and 95% Confidence Intervals (95% CI) for the main outcomes: TFAR (MD = 72.4 min; 95% CI = 10.22-134.58 min; p < 0.001; I2= 99.8%; GRADE: very low); opioid consumption (MD = -7.2 mg (95% CI = -9.30 - -5.09; p < 0.001; I2= 98%; GRADE: very low). VAS pain scores within the first six PO hours (VAS) (MD = -1.01 cm; 95% CI = -1.40-0.64 cm; p < 0.001; I2= 88%; GRADE: very low), at 24 hours (MD = -0.56 cm; 95% CI = -1.14-0.01 cm; p= 0.05; I2= 97%; GRADE: very low). Conclusions Magnesium sulfate delayed TFAR and decreased 24-hour opioid consumption and early postoperative pain intensity. However, imprecision and inconsistency pervaded meta-analyses, causing very low certainty of effect estimates.

RESUMO

BACKGROUND: This randomized trial compared perineural dexamethasone with combined perineural dexamethasone-dexmedetomidine for ultrasound-guided infraclavicular block. We hypothesized that the combination of perineural adjuvants would result in a longer motor block. METHODS: Fifty patients undergoing upper limb surgery with ultrasound-guided infraclavicular block (using 35 mL of lidocaine 1%-bupivacaine 0.25% with epinephrine 5 µg/mL) were randomly allocated to receive perineural dexamethasone (2 mg) or combined perineural dexamethasone (2 mg)-dexmedetomidine (50 µg). After the performance of the block, a blinded observer assessed the success rate (defined as a minimal sensorimotor composite score of 14 out of 16 points at 30 min), the onset time (defined as the time required to reach a minimal composite score of 14 points) as well as the incidence of surgical anesthesia (defined as the ability to complete surgery without local infiltration, supplemental blocks, intravenous opioids or general anesthesia).Postoperatively, the blinded observer contacted patients with successful blocks to inquire about the duration of motor block, sensory block and postoperative analgesia. RESULTS: No intergroup differences were observed in terms of success rate, onset time and surgical anesthesia. Compared with dexamethasone alone, combined dexamethasone-dexmedetomidine provided longer durations of motor block (21.5 (2.7) vs 17.0 (3.9) hours; p<0.001; 95% CI 2.6 to 6.4), sensory block (21.6 (3.6) vs 17.2 (3.6) hours; p<0.001; 95% CI 2.2 to 6.5), and postoperative analgesia (25.5 (9.4) vs 23.5 (5.6) hours; p=0.038; 95% CI 1.0 to 7.7). CONCLUSION: Compared with perineural dexamethasone (2 mg) alone, combined perineural dexamethasone (2 mg)-dexmedetomidine (50 µg) results in longer durations of sensorimotor block and analgesia. Further studies are required to determine the optimal dosing combination for dexamethasone-dexmedetomidine. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov identifier: NCT04875039.
