RESUMEN

Pelvic endometriosis is a well-known clinical risk factor for pelvic inflammation and adhesions. We present a complex case of a woman undergoing a cesarean section where the traditional incision on the anterior lower uterine segment was not possible due to a congested pelvis. The newborn was delivered using a posterior uterine wall incision with rotation of the round ligament.

RESUMEN

Background: Bleeding is a serious cause of hypotension and tachycardia after childbirth and should always be considered. Case presentation: A healthy woman in her thirties who had previously undergone caesarean section, underwent induction and operative vaginal delivery. Postpartum, she experienced chest pain, hypotension and tachycardia, and had signs of ischaemia on electrocardiogram. A CT scan showed a large intraperitoneal haematoma. The patient underwent immediate laparotomy and received a massive blood transfusion. However, no large haematoma was found. The chest pain was attributed to a myocardial infarction caused by hypovolaemic shock. After discharge, the patient experienced significant vaginal bleeding and was transferred to a different university hospital. A CT scan revealed a large retroperitoneal haematoma. Emergency surgery was performed based on the suspicion of active bleeding, but only an older haematoma was found. Re-evaluation of the initial CT scan revealed that the haematoma was in fact located retroperitoneally and was thereby not found in the first operation. Interpretation: This case highlights the importance of bleeding as an important cause in unstable postpartum patients. Additionally, it is a reminder that retroperitoneal haematomas can occur in obstetric patients and can mask typical symptoms of uterine rupture such as abdominal pain. also hindering perioperative diagnosis.

RESUMEN

OBJECTIVE: Aim: To clarify the association between different types of uterine contractility dysfunction and the inflammation of the uterus and chorioamniotic membranes. PATIENTS AND METHODS: Materials and Methods: The association between the inflammation of the uterine layers, chorioamniotic membranes, umbilical cord, and different types of labor activity abnormalities was examined in 382 patients with singleton pregnancies at 28-42 weeks' gestation who underwent Caesarean section (CS) for abnormal uterine contractions and other complications. Statistical analyses included the Mann-Whitney U, Chi-squared test, and logistic regression. RESULTS: Results: In the control group, slight infiltration with polymorphonuclear leukocytes (PMNs) and macrophages of the myometrium and decidua of the lower uterine segment at term pregnancy was found in 59.7% and 73.6% of cases. The main clinical risk factors for placental and decidual membrane inflammation in patients with excessive uterine activity (EUA) were prematurity, multiparity, group B streptococcus (GBS) colonization, and duration of ruptured fetal membranes before the CS. Moderate or marked myometrial inflammation of both uterine segments in the EUA group was diagnosed only in patients with cervical dilation of >6 cm and duration of labor of >8h. In women with hypotonic uterine activity (HUA), decidual and myometrial inflammation was significantly associated with nulliparity and intrapartum factors, such as protracted active first stage of labor, advanced cervical dilation, and number of vaginal examinations. In all cases, inflammation of the myometrium was accompanied by deciduitis. CONCLUSION: Conclusions: Mild inflammation of the decidual membrane and myometrium of the lower segment at term pregnancy is a common physiological phenomenon contributing to labor initiation. Uterine hyperfunction comes as the response of the unaffected myometrium to the release of high concentrations of proinflammatory cytokines produced by the inflamed decidual and chorioamniotic membranes into the bloodstream. Marked myometrial inflammation that occurs in prolonged labor is an additional factor aggravating the hypotonic uterine activity.

RESUMEN

BACKGROUND: Most German hospitals do not offer a trial of labour after two caesarean sections (TOLA2C). TOLA2C is claimed to be associated with too many complications, above all the high risk of uterine rupture. The objective of this study is to review our experience with TOLA2C, with special attention paid to the risk and probability of uterine ruptures. Secondary outcomes include comparing neonatal and maternal outcomes in the group of TOLA2C with the group of elective repeat caesarean section (ERCS) and to assess the success rate for vaginal birth after two caesarean sections (VBAC-2). METHODS: The retrospective cohort study was conducted in a community hospital in North Rhine-Westphalia. Inclusion criteria were all pregnant women with two caesarean sections in their medical history, with a current vertex singleton pregnancy and the absence of morphological abnormalities of the foetus, who gave birth in our facility between January 2015 and June 2021. Descriptive statistics were calculated and Kolmogorov-Smirnov tests, Mann-Whitney U tests, Fishers exact tests, Chi2 -tests and t-tests for independent samples were performed. RESULTS: A total of 91 cases were included in the TOLA2C-group. These were compared to 99 cases that, within the same time frame, had an elective repeat caesarean section (ERCS-group). There was no statistically significant difference found in the neonatal outcome between the two groups (except for the neonatal pH-value: p 0.024). The hospital stay was significantly shorter in the TOLA2C-group, while maternal complication rates were almost similar (13.2% in the TOLA2C-Group, vs. 16.2% in the ERCS-Group). The success rate for TOLA2C was 55%. No complete uterine rupture was found, but in three cases an incomplete rupture (3.3% rate for incomplete uterine ruptures) occurred, but had no influence on the neonatal outcome. CONCLUSION: TOLA2C is not associated with a worse maternal or neonatal outcome compared to ERCS, and especially the risk of complete uterine ruptures seems to be low. TOLA2C should be more widely offered to suitable patients who are motivated for it.

RESUMEN

OBJECTIVE: We aimed to probe the diagnostic value of transvaginal color Doppler ultrasound (TV-CDU) parameters in cesarean scar pregnancy (CSP) and CSP sub-types, and the relevant factors affecting patients' surgical effects. METHODS: Seventy-five CSP patients (all requested termination of pregnancy) were selected as the observation group, and 75 normal pregnant women with a history of cesarean section were selected as the control group. All the study subjects underwent TV-CDU and their cesarean scar muscle (CSM) thickness, minimum sagittal muscle thickness and resistance index (RI) of blood flow in the anterior wall of the lower uterine segment were calculated. The diagnostic value of CSM, minimum sagittal muscle thickness, and RI for CSP and CSP sub-types was analyzed. The patients in the observation group were grouped into the effective group and the ineffective group according to whether the surgical treatment was effective or not, and the independent factors affecting CSP efficacy were analyzed. RESULTS: The observation group had lower CSM, minimum sagittal muscle thickness and RI than the control group. CSM, RI, and minimum sagittal thickness in patients with type II CSP were lower than those in patients with type I, and these indicators in patients with type III were lower than those in patients with type II. The area under the curve (AUC) of CSM, RI and minimum sagittal muscle thickness in combination for CSP diagnosis and the AUC for CSP sub-types were higher than those of each indicator alone. Gestational sac size and CSM were independent factors affecting CSP treatment. CONCLUSION: Changes in TV-CDU parameters facilitates CSP diagnosis after cesarean section. CSM, minimum sagittal muscle thickness changes, and RI in combination possesses high value for CSP diagnosis and CSP sub-types. Gestational sac size and CSM are independent factors affecting CSP treatment.

RESUMEN

OBJECTIVE: To compare the maternal and neonatal morbidity in patients with transvaginal (TVC) versus transabdominal (TAC) cerclage. MATERIALS AND METHODS: Retrospective analysis of patients who received cervical cerclage and terminated the pregnancy in the second trimester or third trimester in two tertiary hospitals. Data on basic clinical characteristics, predelivery maternal morbidity, intrapartum morbidity, postpartum morbidity and neonatal morbidity of TVC patients and TAC patients were analysed and compared. RESULTS: Seventy-two TVC patients and 120 TAC patients were included. The rates of abnormal fetal presentation and placental disorders were significantly higher in TAC patients than that in TVC patients (21.67% vs 5.56% and 18.33% vs 4.17%, respectively). The rates of premature rupture of membranes and intrauterine infection were significantly higher in TVC patients than that in TAC patients (25.00% vs 2.50% and 11.23% vs 3.33%, respectively). Compared with TVC patients, the rates of estimated intrapartum hemorrhage ≥500 ml, uterine rupture and cesarean delivery in the third trimester were significantly higher in TAC patients than in TVC patients. Gestational age at delivery and neonatal morbidity were comparable between TVC patients and TAC patients. CONCLUSION: Compared with TVC patients, TAC patients were associated with a significantly higher incidence of maternal morbidity in placental disorders, abnormal fetal presentation, intrapartum hemorrhage ≥500 ml and uterine rupture.

RESUMEN

OBJECTIVE: This study aims to assess the clinical efficacy and safety of combining high-intensity focused ultrasound (HIFU) with ultrasound-guided suction curettage for the treatment of cesarean scar pregnancy (CSP) at different time intervals. METHODS: A total of 115 CSP patients were enrolled and divided into two groups based on the time between HIFU ablation and suction curettage. Group A (n = 50) underwent suction curettage 24-48 h after HIFU ablation, while Group B (n = 65) had suction curettage within 6 h of HIFU ablation. The study compared and analyzed the clinical characteristics, treatment success rates, and intraoperative hemorrhage during ultrasound-guided suction curettage. RESULTS: The demographic characteristics of the two groups were similar, with no statistically significant differences observed in HIFU parameters, treatment success rates, blood loss, the use of Foley catheter balloons, or hospital expenses (p > 0.05). Importantly, suction curettage performed within 6 h after HIFU ablation resulted in shorter hospitalization times compared to suction curettage performed 24-48 h after the ablation (p < 0.05). CONCLUSIONS: Suction curettage within 6 h after HIFU ablation is an effective, safe, and cost-efficient treatment for patients diagnosed with CSP.

RESUMEN

BACKGROUND: Placental accreta spectrum disorders (PAS) are a high-risk group for severe postpartum hemorrhage (SPPH), with the incidence of PAS increasing annually. Given that cesarean section and anterior placenta previa are the primary risk factors for PAS, therefore, our study aims to investigate the predictive value of clinical characteristics and ultrasound indicators for SPPH in patients with anterior placenta previa combined with previous cesarean section, providing a theoretical basis for early prediction of SPPH. METHODS: A total of 450 patients with anterior placenta previa combined with previous cesarean section were retrospectively analyzed at Shengjing Hospital affiliated with China Medical University between January 2018 and March 2022. Clinical data and ultrasound indicators were collected. Patients were categorized into SPPH (blood loss >2000mL, 182 cases) and non-SPPH (blood loss ≤ 2000mL, 268 cases) groups based on the blood loss within 24 h postpartum. The population was randomly divided into training and validation cohorts at a 7:3 ratio. LASSO and multifactorial logistic regression analyses were utilized to identify independent risk factors for SPPH. Accordingly, a nomogram prediction model was constructed, the predictive performance was assessed using receiver operating characteristic (ROC) curves, calibration curves and decision curve analysis (DCA). RESULTS: Among the 450 patients, 182 experienced SPPH (incidence rate, 40.44%). Preoperative systemic immune-inflammatory index, preoperative D-dimer level, preoperative placenta accreta spectrum ultrasound scoring system (PASUSS) score, and one-step-conservative surgery were identified as independent risk factors for SPPH in patients with anterior placenta previa combined with previous cesarean section. A nomogram was constructed based on these factors. The areas under the ROC curves for the training and validation cohorts were 0.844 (95%CI: 0.801-0.888) and 0.863 (95%CI: 0.803-0.923), respectively. Calibration curves and DCA indicated that this nomogram demonstrated good predictive accuracy. CONCLUSIONS: This nomogram presents an effective and convenient prediction model for identifying SPPH in patients with anterior placenta previa combined with previous cesarean section. It can guide surgical planning and improve prognosis.

RESUMEN

BACKGROUND: Cesarean scar pregnancy is a complicated and potentially life-threatening type of ectopic pregnancy. There is no gold standard for its management. The aim is to demonstrate the efficacy and safety of treatment by hysteroscopic tissue removal system after systemic methotrexate injection. METHODS: We report the case of a 27-year-old patient who had previously had a C-section and who presented herself to the emergency room with pelvic pain and metrorrhagia. The human chorionic gonadotrophin (hCG) serum level was positive. The exploration revealed an ectopic pregnancy on the cesarean scar. She benefited of 4 systemic injections of methotrexate. As the hCG became negative, endovaginal ultrasound confirmed the avascular nature of the mass. Surgical resection by mechanical morcellation hysteroscopy (TruClear™) was performed under general anaesthesia, visual control and ultrasound guidance. RESULTS: This procedure was successful. It was an ambulatory procedure and there were neither intra- nor postoperative complications. CONCLUSIONS: To our knowledge, this is the first time in Belgium that a hysteroscopic tissue removal system procedure has been used to treat a caesarean scar pregnancy. This technique seems to be safe for both the patient and the surgeon and could become a new approach for cesarean scar pregnancy management.

CONTEXTE: La grossesse sur cicatrice de césarienne est définie comme la présence d'un sac gestationnel dans une isthmocèle créée par une hystérotomie préalable. Il n'existe pas de gold standard concernant sa prise en charge. L'objectif est de démontrer l'efficacité et la sécurité du traitement par résection mécanique hystéroscopique des tissus après injection systémique de méthotrexate. Méthodes : Nous rapportons le cas d'une patiente de 27 ans ayant déjà eu une césarienne et qui s'est présentée aux urgences avec des douleurs pelviennes et des métrorragies. L'exploration révèle une grossesse sur la cicatrice de césarienne. Elle a bénéficié de 4 injections systémiques de méthotrexate. La résection des résidus trophoblastiques avasculaires a été réalisée par voie hystéroscopique en utilisant l'hystéroscope par action mécanique de type -TruClear™ et ce, sous contrôle échographique concomitant. Résultats : Cette procédure ambulatoire effectuée sous anesthésie générale a été un succès. Il n'y a eu aucune complication per- ou postopératoire. CONCLUSIONS: À notre connaissance, c'est la première fois qu'une résection par action mécanique des résidus trophoblastiques sur cicatrice de césarienne est réalisée en Belgique. Cette technique semble sûre pour la patiente et le chirurgien et pourrait devenir une nouvelle approche pour la prise en charge d'une grossesse sur cicatrice de césarienne.

RESUMEN

OBJECTIVE: This study aimed to investigate whether the administration of intrathecal dexmedetomidine as a bupivacaine adjuvant for caesarean section can prolong the duration of analgesia compared with bupivacaine alone. Secondary outcomes included postoperative pain, the time interval to the first analgesic request, the level of sedation, the incidence of adverse effects, and the fetal outcomes. MATERIALS AND METHODS: A systematic review and meta-analysis were conducted. The study compared the intrathecal administration of bupivacaine plus dexmedetomidine (group BD) to the intrathecal administration of bupivacaine alone (group B) for cesarean sections. RESULTS: Fourteen publications were included. Among patients who underwent spinal anesthesia for a cesarean section, 514 patients received intrathecal bupivacaine alone, and 533 patients received intrathecal bupivacaine plus dexmedetomidine. The onset of sensory and motor block was essentially the same in both groups; the time for sensory and motor block regression was significantly longer in the BD group. Postoperative Visual Analogue Scale (VAS) values were similar in group BD when compared to group B. Postoperative VAS scores remained consistently low in Group BD compared to Group B, starting from 1 hour after surgery. The level of sedation measured at the end of the cesarean section in both groups was almost similar. No difference in terms of safety, adverse events, and neonatal outcomes was found between the two groups. CONCLUSIONS: Use of intrathecal dexmedetomidine for spinal anesthesia in cesarean section significantly prolongs sensory and motor block compared to using bupivacaine alone as an adjuvant. It also improves analgesia after 1 hour with no difference in the incidence of maternal and neonatal adverse effects compared to bupivacaine alone. The optimal dose of dexmedetomidine to use remains to be ingested.

RESUMEN

AIM: Hypothermia is one of the common complications of cesarean section, which has a serious impact on intraoperative surgical safety and postoperative recovery of pregnant women. Mitigation of the risk factors of hypothermia in pregnant women undergoing cesarean section may reduce the probability of its occurrence and improve the perioperative comfort of pregnant women. Therefore, this study systematically evaluates the influencing factors of hypothermia in patients undergoing cesarean section, aiming to provide references for the prevention of hypothermia in pregnant women undergoing cesarean section. METHODS: A systematic search was conducted across various databases, including PubMed, Cochrane Library, Embase, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang, and Chinese Biomedical Literature databases to gather observational studies on the factors affecting hypothermia in pregnant women undergoing cesarean section. The search deadline was January 30, 2024. Two researchers independently screened literature, extracted data, evaluated quality, and crosschecked the outcomes. Meta analysis was conducted using RevMan 5.3 and Stata17.0. RESULTS: Twelve studies were included in this review, all of which were case-control studies conducted from 2014 to 2022, encompassing a total of 5561 pregnant women. The quality of the studies included was average or above. The meta-analysis results showed that body mass index (mean difference (MD) = -1.47; 95% confidence interval (CI) [-2.84, -0.11]; p = 0.03), operating room temperature (odds ratio (OR) = 2.08; 95% CI [1.56, 2.76]; p < 0.00001), anesthesia method (OR = 1.84; 95% CI [1.40, 2.42]; p < 0.0001), fluid loss (MD = 160.09; 95% CI [77.31, 242.87]; p = 0.0002), flushing volume (MD = 66.43; 95% CI [8.46, 124.40]; p = 0.02), and hypothyroidism (OR = 2.29; 95% CI [1.61, 3.27]; p < 0.00001) were risk factors for perioperative hypothermia in pregnant women undergoing cesarean section (p < 0.05). CONCLUSIONS: The occurrence of hypothermia in pregnant women during the perioperative period is influenced by factors such as low body mass index, spinal anesthesia, low operating room temperature, intraoperative fluid loss, large flushing volume, and hypothyroidism.

RESUMEN

BACKGROUND: Obstetric fistulas are abnormal open connection(s) between the vagina and the urinary tract or the rectum resulting from tragic injuries sustained by mothers during childbirth that lead to urine and/or faecal incontinence. Due to the rapidly growing middle class in sub-Saharan Africa (SSA) and the corresponding quest for hospital delivery and caesarean section, surgery-related (iatrogenic) obstetric fistulas are on the rise. Worryingly, there is scanty data on surgery-related fistulas. This review aims to collate empirical evidence on the magnitude of iatrogenic obstetric fistulas in SSA, generate country-specific data and explore factors that influence obstetric surgery-related fistulas. METHODS: All relevant databases, PubMed, LILACS, CINAHL, SCOPUS and Google Scholar will be searched from 1st January 2000 to 31st March 2024 using search terms developed from the major concepts in the title without restrictions by language. The Cochrane Library, African Journals Online, Data Base of African Thesis and Dissertations Including Research (DATAD-R D Space) and preprint repositories will also be searched. Reference lists of relevant studies will be searched and experts in the field will be contacted for additional (unpublished) studies. The search output will be exported to Endnote where duplicate studies will be removed. The deduplicated studies will be exported to Rayyan where study screening and selection will be conducted. At least two authors will independently select studies, extract data and assess quality in the included studies using pretested tools. Disagreements between reviewers will be resolved through discussion. Data analysis will be performed with RevMan 5.4. Comparative binary outcomes will be reported as odds ratio (OR) or risk ratio (RR) and for continuous outcomes, mean difference and standard deviations (SDs) will be used. Non-comparative studies will be analysed as weighted proportions. Heterogeneity between studies will be assessed graphically and statistically, and where a significant level is detected, the random-effects model meta-analysis will be performed. All estimates will be reported with their 95% confidence intervals (CIs). Where data permit, we will conduct subgroup and sensitivity analyses to test the robustness of the estimates on key quality domains. The overall quality of the evidence will be assessed using GRADE (Grading of Recommendations Assessment, Development and Evaluation). EXPECTED STUDY OUTCOMES: This systematic review and meta-analysis uses rigorous methods and best practices to attempt to collate all empirical evidence and estimate country-specific proportions of iatrogenic (surgery-related) fistulas among obstetric fistula patients across countries in SSA. This review will explore context-specific variables, provide insights into their impact and relate them to the type and experience of personnel performing the obstetric procedures that lead to obstetric fistulas. The findings of the full review are expected to inform the development of national and regional Training Programs for Medical Officers, support the development of a consensus "minimum acceptable standard of care" and inform quality assurance standards for clinicians involved in the provision of surgical obstetric care.

RESUMEN

BACKGROUND: Postpartum depression is a major psychiatric disorder associated with maternal suicide and child developmental disturbances. In this study, we aimed to investigate whether general anesthesia for cesarean delivery is associated with a higher rate of new-onset depression after delivery than neuraxial anesthesia. METHODS: This is a nationwide retrospective cohort study using data retrieved from the National Health Insurance Research Database between 2014 and 2018. Women who had cesarean delivery under general or neuraxial anesthesia were enrolled. After 1:4 propensity score matching, there were 4544 and 18,176 women under the general and neuraxial anesthesia groups, respectively. The primary outcome was new-onset depression diagnosed after delivery in a time-to-event analysis setting. RESULTS: After propensity-score matching, the rate of new-onset depression diagnosed within 1 year was 1.10 % (50/4488) and 0.86 % (157/18176) after cesarean delivery under general and neuraxial anesthesia, respectively. For depression diagnosed within 90 days of delivery, significant difference between the two groups was noted (0.51 % vs. 0.30 %, P = 0.031). In the time-to-event analysis with Cox regression model, women who delivered under general anesthesia were associated with significantly higher risk of postpartum depression within 90 days (Hazard ratio [HR], 1.71; 95 % CI, 1.05-2.79) compared with those under neuraxial anesthesia. LIMITATIONS: The observational design only allows asserting association, rather than establishing causality between exposure and outcomes. CONCLUSIONS: Women who underwent cesarean delivery under general anesthesia had a higher risk of subsequent depression within 90 days than those under neuraxial anesthesia. Early screening for depressive disorders might facilitate timely management.

RESUMEN

Renal angiomyolipoma (rAML) is a rare benign tumour primarily affecting women due to hormonal influences, with accelerated growth observed during pregnancy. This case report presents a multigravida woman in her mid-20s at 37 weeks of gestation with stable vital signs and normal physical examination findings, except for swelling in the lower extremities. Following caesarean section delivery, she developed flank pain and haematuria in the immediate postoperative period. Emergency surgery revealed a ruptured rAML, resulting in unstable haemodynamics and significant blood loss. A multidisciplinary team performed a left radical nephrectomy to control bleeding. The patient required transfusions, ventilation and postoperative antibiotic therapy. This case underscores the importance of considering rAML rupture in the immediate postoperative period following caesarean section, highlighting the need for prompt evaluation in pregnant women with a history of urologic disorders.

RESUMEN

Postpartum sepsis following caesarean sections among women in Uganda remains a risk. However, erratic supplies of standard dressing material make the risk a reality. Alternative wound dressing materials, therefore, remain a viable option. This study examined the outcome of a honey and olive oil-based dressing material on caesarean section wound healing. Using the Uganda Industrial Research Institute (UIRI), the study team created I-Dress, a wound dressing made of honey and olive oil. A case-series study was conducted on 25 women who received I-Dress following caesarean births at three health facilities in south-west Uganda. Vital signs (temperature, blood pressure, and heart rate) were measured, along with wound induration, dehiscence, and discharge. The primary outcome was the length of time it took for the wound to heal. The average age of the women who received I-Dress was 27.5 (±4.8) years. Following the application of I-Dress, all of the women (100%) had no wound induration or dehiscence, with only two (13%) experiencing wound discharge. The vast majority of the women (88%) had never had a Caesarean section before. The mean time required for wound healing was 2.2 (±0.7) days. The findings indicate that honey and olive oil-based dressings improve Caesarean section wound healing in terms of wound induration, dehiscence, and time to healing. These dressing materials can therefore supplement the standard dressing materials, especially in resource-constrained settings.

RESUMEN

Background and objectives: The frontal QRS-T angle is a novel parameter of myocardial repolarization. Weight gain during pregnancy and physiological changes during a cesarian section may affect the frontal QRS-T angle. We aimed to assess the effect of body mass index (BMI) on the frontal QRS-T angle in pregnant women undergoing cesarean section with spinal anesthesia. Method and materials: This study included 90 pregnant women. BMI was calculated for all pregnant women. The study population was divided into two groups: BMI < 30 (n = 66) and BMI ≥ 30 (n = 24). QT interval measurements and the frontal QRS-T angle were obtained from the report of an electrocardiography machine. Results: It was found that the pre-operative and post-operative frontal QRS-T angle (p = 0.045 and p = 0.007) and QTc interval (p = 0.037 and p < 0.001) were higher in pregnant women with a BMI ≥ 30 than in pregnant women with a BMI < 30. In addition, when compared to pre-operative values, the post-operative frontal QRS-T angle (from 24.0 [20.0-41.5] to 34.5 [19.5-50.0], p = 0.031) and QTc interval (from 420.6 ± 13.3 to 431.7 ± 18.3, p = 0.010) were increased in the BMI ≥ 30 group, whereas no significant post-operative increase was observed in the BMI < 30 group. In correlation analysis, BMI was positively correlated with the frontal QRS-T angle and QTc interval. Conclusions: The frontal QRS-T angle and QTc interval were importantly increased in pregnant women with a BMI ≥ 30 than in pregnant women with a BMI < 30. Also, after cesarean section operation with spinal anesthesia, the frontal QRS-T angle and QTc were increased significantly in the BMI ≥ 30 group, whereas no significant change was observed in the BMI < 30 group. Therefore, it is suggested to perform close post-operative monitoring in pregnant women with a BMI ≥ 30 undergoing cesarean section with spinal anesthesia.

RESUMEN

Objective: For elective cesarean section patients with gestational diabetes mellitus (GDM), there is a lack of evidence-based research on the use of enhanced recovery after surgery (ERAS). This study aims to compare the ERAS after-surgery protocol and traditional perioperative management. Research design and methods: In this retrospective cohort study, singleton pregnancies with good glucose control GDM, delivered by elective cesarean sections under intravertebral anesthesia at least 37 weeks from January 1 to December 31, 2022, were collected at the Third Affiliated Hospital of Sun Yat-sen University. We divided all enrolled pregnant women and newborns into an ERAS group and a control group (the traditional perioperative management group) based on their adherence to the ERAS protocol. The primary outcome was the preoperative blood glucose level, with an increase of more than 1 mmol/L indicating clinical significance when compared to the control group. The secondary outcome was centered around an adverse composite outcome that affected both mothers and newborns. Results: We collected a total of 161 cases, with 82 in the ERAS group and 79 in the control group. Although the mean preoperative blood glucose level in the ERAS group was significantly higher than in the control group (5.01 ± 1.06 mmol/L vs. 4.45 ± 0.90 mmol/L, p<0.001), the primary outcome revealed that the mean glycemic difference between the groups was 0.47 mmol/L (95% CI 0.15-0.80 mmol/L), which was below the clinically significant difference of 1 mmol/L. For the secondary outcomes, the ERAS group had an 86% lower risk of a composite adverse outcome compared to the control group. This included a 73% lower risk of perioperative maternal hypoglycemia and a 92% lower rate of neonatal hypoglycemia, all adjusted by age, hypertensive disorder of pregnancy, BMI, gestational weeks, primigravidae, primary pregnancy, GDM, surgery duration, and fasting glucose. Conclusion: Implementing a low-dose carbohydrate ERAS in pregnant women with GDM prior to elective cesarean section, compared to traditional perioperative management, does not lead to clinically significant maternal glucose increases and thus glucose-related maternal or neonatal perioperative complications.
