RESUMO
OBJECTIVE: We aimed to investigate the effect of bilateral sphenopalatine ganglion blockade (SPGB) on the main postoperative complications in septorhinoplasty operations. METHODS: In this randomized, controlled, prospective study, 80 cases planned for Septorhinoplasty operations under general anesthesia were included in the study. The cases were divided into two groups; SPGB was performed with 2â¯mL of 0.25% bupivacaine bilaterally 15â¯min before the end of the operation in the SPGB group (Group S, nâ¯=â¯40). In the control group (Group C, nâ¯=â¯40), 2â¯mL of 0.9% NaCl solution was applied into both SPG areas. In the recovery unit after the operation; the pain and analgesic needs of the patients at 0, 2, 6 and 24â¯h were evaluated. RESULTS: There was no statistically significant difference between the groups in terms of hemodynamic parameters (ASA, MBP, HR) (pâ¯>â¯0.05) All VAS values were statistically lower in Group S than in Group C (pâ¯<â¯0.05). In Group S, the need for analgesic medication was found in 5 cases between 0-2â¯h, whereas in Group C, this rate was found in 17 cases, and it was statistically significant (pâ¯<â¯0.05). CONCLUSION: Bilateral SPGB application was determined to provide better analgesia in the early postoperative period compared to the control group, it was concluded that further studies are needed to say that there are significant effects on laryngospasm and nausea-vomiting. LEVEL OF EVIDENCE: 2, degree of recommendation B.

RESUMO
Abstract Introduction: Post-anesthetic complications, particularly respiratory complications, continue to be a source of concern due to their high frequency, particularly in pediatrics. Objective: To describe the incidence of respiratory complications in the post-anesthesia care unit of an intermediate complexity center during a six-month period, and to explore the variables associated with major respiratory complications. Materials and Methods: Retrospective cohort study based on clinical record reviews. The records of the post-anesthesia care unit of an intermediate complexity pediatric institution located in Medellin, Colombia, were reviewed. This center uses a nursing-based care model that includes patient extubation in the post-anesthesia care unit. Results: The records of 1181 patients were analyzed. The cumulative incidences of major complications were bronchospasm 1.44%, laryngospasm 0.68% and respiratory depression 0.59%. There were no cases of cardiac arrest or acute pulmonary edema. A history of respiratory infection less than 15 days before the procedure, rhinitis and female sex were associated with major respiratory complications. Conclusions: A low frequency of respiratory complications was found during care provided by nursing staff trained in anesthesia recovery and pediatric airway in the post-anesthesia care unit.

Introduction: Laryngospasm is a complication feared by anesthesiologists. It is associated with bronchospasm, hypoxia, arrhythmias, aspiration of gastric contents, and cardiac arrest. It is more common among neonates and infants. It is closely related to the type of surgery and consists in an intense and prolonged closure of the glottis in response to direct or reflex glottic stimulation. Objective: To describe the management of reflex partial laryngospasm in a pediatric patient during a urological intervention. Case presentation: 18-month-old patient who received meatotomy. During surgery, he presented reflex partial laryngospasm managed with physical maneuvers, without the need to use medication or the mechanic airways ventilation. Conclusions: The maneuvers used are safe and effective for the management of reflex laryngospasm without the need to address the airway or using of medications. Satisfactory outcomes were achieved with a risk-benefit ratio in favor of the patient(AU)

Non-dystrophic myotonias are a group of rare neuromuscular diseases linked to SCN4A or CLCN1. Among the subtypes, myotonia permanens, associated with the Gly1306Glu variant of SCN4A, is a relatively less frequent but more severe form. Most reports of non-dystrophic myotonias describe European populations. Therefore, to expand the genetic and phenotypic spectrum of this disorder, we evaluated 30 Chilean patients with non-dystrophic myotonias for associated variants and clinical characteristics. SCN4A variants were observed in 28 (93%) of patients, including 25 (83%) with myotonia permanens due to the Gly1306Glu variant. Myotonia permanens was inherited in 24 (96%) patients; the mean age of onset was 6 months, and the initial symptoms were orbicularis oculi myotonia in 17 (74%) patients and larynx myotonia in 12 (52%) patients. The extraocular muscles were involved in 11 (44%) patients, upper limbs in 20 (80%), and lower limbs in 21 (84%). Thirteen (52%) patients experienced recurrent pain and 10 (40%) patients reported limitations in daily life activities. Carbamazepine reduced myotonia in eight treated patients. The high frequency of the Gly1306Glu variant in SCN4A in Chilean patients suggests a founder effect and expands its phenotypic spectrum.

Brief resolved unexplained events (BRUEs) have numerous and varied causes posing a challenge to investigation and management. A subset of infants with the neuromuscular disorder sodium channel myotonia, due to mutations in the SCN4A gene, experience apnoeic events due to laryngospasm (myotonia) of the upper airway muscles that may present as a BRUE. We sought to ascertain the frequency, severity and outcome of infants carrying the G1306E SCN4A mutation commonly associated with this presentation. We report 12 new cases of individuals with the G1306E mutation from three unrelated families and perform a literature review of all published cases. Infants with the G1306E mutation almost universally experience laryngospasm and apnoeic events. The severity varies significantly, spans both low and high-risk BRUE categories or can be more severe than criteria for a BRUE would allow. At least a third of cases require intensive care unit (ICU) care. Seizure disorder is a common erroneous diagnosis. Apnoeas are effectively reduced or abolished by appropriate treatment with anti-myotonic agents. Probands with the G1306E mutation who are family planning need to be counselled for the likelihood of post-natal complications. There is readily available and extremely effective treatment for the episodic laryngospasm and apnoea caused by this mutation. Proactively seeking clinical evidence of myotonia or muscle hypertrophy with consideration of CK and EMG in high risk BRUEs or more complex apnoeic events may reduce avoidable and prolonged ICU admissions, patient morbidity and potentially mortality.
RESUMO
OBJECTIVES: To determine the incidence of potentially life-threatening complications of hypocalcemia in infants and children in Olmsted County, Minnesota; and to determine if vitamin D deficiency contributed to these events and was, at the time of clinical presentation, considered as a possible cause. STUDY DESIGN: In this population-based descriptive study, data were abstracted from the Rochester Epidemiology Project, a medical record linkage system covering 95% of patients in Olmsted County, Minnesota. Participants were children aged 0-5 years who resided in Olmsted County between January 1, 1996 and June 30, 2017, and who received diagnoses of seizures, cardiomyopathy, cardiac arrest, respiratory arrest, laryngospasm, and/or tetany. The incidence of hypocalcemia plus a potentially life-threatening complication was calculated. RESULTS: Among 15â419 patients aged 0-5 years in Olmsted County during the study period, 1305 had eligible complications: 460 had serum calcium checked within 14 days of presentation and 85 had hypocalcemia. Patients were excluded when causes other than hypocalcemia likely triggered the complication, leaving 16 children whose complication was attributed to hypocalcemia. Three of these 16 patients had a serum 25-hydroxyvitamin D measurement and 2 were deficient (≤6 ng/mL [15 nmol/L]). Among children aged 0-5 years, the incidence of hypocalcemia plus a potentially life-threatening complication was 6.1 per 100â000 person-years (95% CI, 3.5-10.0). CONCLUSIONS: Vitamin D deficiency is an underinvestigated cause of complications of hypocalcemia in children. Serum calcium and 25-hydroxyvitamin D should be measured in children with these complications to identify possibly life-threatening vitamin D deficiency.

Abstract Background Post-extubation laryngospasm is a dangerous complication that should be managed promptly. Standard measures were described for its management. We aimed to compare the efficacy of propofol (0.5 mg.kg-1) vs. lidocaine (1.5 mg.kg-1) for treatment of resistant post-extubation laryngospasm in the obstetric patients, after failure of the standard measures. Method This study was conducted over 2 years on all obstetric patients scheduled for cesarean delivery. Post-extubation laryngospasm was initially managed with a standard protocol (removal of offending stimulus, jaw thrust, positive pressure ventilation with 100% oxygen). When this protocol failed, the tested drug was the second line (lidocaine in the first year and propofol in the second year). Lastly, succinylcholine was used when the tested drug failed. Results In lidocaine group, 5% of parturients developed post-extubation laryngospasm, 31.9% of them were successfully treated via standard protocol, and 68.1% required lidocaine treatment. Among these, 65.6% of patients treated with lidocaine responded successfully and 34.4% required succinylcholine to relieve laryngospasm. In propofol group, 4.7% of parturients developed post-extubation laryngospasm, 30.1% of them were successfully treated via standard protocol, and 69.9% required propofol treatment. Among these, 82.8% of patients treated with propofol responded successfully and 17.2% required succinylcholine to relieve laryngospasm. Conclusion Small dose of propofol (0.5 mg.kg-1) is marginally more effective than lidocaine (1.5 mg.kg-1) for the treatment of resistant post-extubation laryngospasm in obstetric patients, after failure of standard measures and before the use of muscle relaxants.
Resumo Justificativa O laringoespasmo pós-extubação é uma complicação perigosa que deve ser prontamente tratada. Medidas padrão para o seu manejo foram descritas. O nosso objetivo foi comparar a eficácia de propofol (0,5 mg.kg-1) versus lidocaína (1,5 mg.kg-1) no tratamento de laringoespasmo resistente pós-extubação em pacientes obstétricas após falha das medidas padrão. Método Este estudo foi conduzido ao longo de dois anos em todas as pacientes obstétricas programadas para cesariana. O laringoespasmo pós-extubação foi inicialmente tratado com um protocolo padrão (remoção do estímulo ofensivo, protrusão mandibular, ventilação com pressão positiva com oxigênio a 100%). Ao constatar a falha desse protocolo, o fármaco testado foi a segunda opção (lidocaína no primeiro ano e propofol no segundo ano). Por fim, succinilcolina foi usada quando houve falha do fármaco testado. Resultados No grupo lidocaína, 5% das parturientes desenvolveram laringoespasmo pós-extubação, 31,9% delas foram tratadas com sucesso via protocolo padrão e 68,1% precisaram de tratamento com lidocaína, das quais, 65,6% responderam com sucesso ao tratamento com lidocaína e 34,4% precisaram de succinilcolina para alívio do laringoespasmo. No grupo propofol, 4,7% das parturientes desenvolveram laringoespasmo pós-extubação, 30,1% delas foram tratadas com sucesso via protocolo padrão e 69,9% precisaram de tratamento com propofol, das quais, 82,8% responderam com sucesso ao tratamento com propofol e 17,2% precisaram de succinilcolina para alívio do laringoespasmo. Conclusão Uma pequena dose de propofol (0,5 mg.kg-1) é marginalmente mais eficaz do que lidocaína (1,5 mg.kg-1) no tratamento de laringoespasmo resistente pós-extubação em pacientes obstétricas, após falha das medidas padrão e antes do uso de relaxantes musculares.

Para determinar fracción espirada final de sevoflurane al retirar tubo orotraqueal y máscara laríngea sin compli-caciones en pacientes pediátricos, se elaboró estudio obser-vacional de tipo descriptivo y, transversal, seleccionando un total de 40 pacientes de pediatría quirúrgica (Hospital Universitario de Caracas) para cirugías urológicas y her-nioplastias, distribuidos en grupo T (tubo orotraqueal) y grupo M (máscara laríngea). Premedicados con Midazo-lam recibieron anestesia inhalatoria y bloqueo regional. Mantenimiento: O2/aire 50/50. Concluida la cirugía se retiró dispositivo según parámetros hemodinámicos, clí-nicos y ventilatorios. Hubo diferencias estadísticamente significativas entre ambos dispositivos para presión arte-rial sistólica y diastólica, tiempo retiro del dispositivo de la vía aérea salida del quirófano (TR) y complicaciones, no para fracción espirada. Se concluyó que para retiro de máscara laríngea y tubo orotraqueal, la fracción espirada final de sevoflurane fue de 0,66 y 0,87 respectivamente, siendo la máscara laríngea el dispositivo más recomenda-do por menor TR y menor número de complicaciones (AU)
To determine end-tidal sevoflurane fraction by removing endotracheal tube and laryngeal mask in pediatric patients without complications was developed observational and descriptive, transversal, selecting a total of 40 surgical pedia-tric patients (Hospital Universitario de Caracas) for surgery hernioplasties urological and distributed in group T (endo-tracheal tube) and group M (laryngeal mask). Premedicated with midazolam received inhalation anesthesia and regional blockade. Maintenance: O2/aire 50/50. Completed surgery withdrew device according to hemodynamic parameters, clinical and ventilator. Significant differences between the two devices for systolic and diastolic blood pressure, while removing the device from the air - out of the operating room (TR), and complications, not fractional exhaled. It was con-cluded that removal of laryngeal mask and endotracheal tube, the end-tidal sevoflurane fraction was 0.66 and 0.87 respectively, and the laryngeal mask device smaller than recommended by TR and fewer complications (AU)

JUSTIFICATIVA E OBJETIVOS: A manutenção das vias aéreas é de importância fundamental para os anestesiologistas, particularmente durante a indução da anestesia e após a extubação, quando ocorre mais frequentemente o espasmo da laringe ou laringoespasmo. O anestesiologista deve conhecer a fisiologia do funcionamento faríngeo-laríngeo e os fatores de risco para a obstrução das vias aéreas, pois se trata de complicação potencialmente grave que pode ocorrer durante procedimento anestésico-cirúrgico, de etiologia multifatorial e cujas consequências podem ser nefastas. O atraso no diagnóstico ou tratamento e a evolução do quadro podem levar à hipoxemia, edema agudo do pulmão e eventualmente óbito do paciente. Nesse contexto o objetivo deste artigo foi rever as medidas que devem ser tomadas em situação de laringoespasmo, já que oxigenação e ventilação adequadas podem ficar comprometidas em tal situação. CONTEÚDO: Este artigo de revisão apresenta os mecanismos de manutenção das vias aéreas, discutindo seus aspectos mais relevantes e etiologia, fisiopatologia, tratamento e prevenção do laringoespasmo. CONCLUSÕES: Há muitas recomendações na literatura que visam tratar ou prevenir o desenvolvimento do laringoespasmo, mas nenhuma é completamente eficaz. Devido à sua gravidade, é necessário que sejam realizados mais estudos com enfoque nas medidas de prevenção dessa complicação.
BACKGROUND AND OBJECTIVES: Airways management is fundamental for anesthesiologists, especially during induction of anesthesia and after extubation, when laryngeal spasm is more common. The anesthesiologist should know pharyngeal-laryngeal physiology and the risk factors for airways obstruction, since this is a potentially severe complication with a multifactorial etiology that can develop during anesthesia and whose consequences can be catastrophic. A delay in the diagnosis or treatment and its evolution can lead to hypoxemia, acute pulmonary edema, and, eventually, death of the patient. In this context, the objective of this report was to review the measures that should be taken in cases of laryngospasm because adequate oxygenation and ventilation may be compromised in this situation. CONTENTS: This review article presents the mechanisms of airways management, discussing the most relevant aspects and etiology, pathophysiology, treatment, and prevention of laryngospasm. CONCLUSIONS: The literature has several recommendations on the treatment or prevention of laryngospasm, but none of them is completely effective. Due to its severity, further studies on measures to prevent this complication are necessary.

El atraso en el diagnóstico o tratamiento y la evolución del cuadro pueden conllevar a la hipoxemia, edema agudo del pulmón y eventualmente al deceso del paciente. En ese sentido, el objetivo de este artículo fue analizar nuevamente las medidas que deben ser tomadas en una situación de laringoespasmo, ya que la oxigenación y la ventilación adecuadas pueden quedar comprometidas en esa situación. CONTENIDO: Este artículo de revisión presenta los mecanismos de mantenimiento de las vías aéreas, discutiendo sus aspectos más relevantes y la etiología, fisiopatología, tratamiento y prevención del laringoespasmo. CONCLUSIONES: Existen muchas recomendaciones en la literatura que objetivan tratar o prevenir el desarrollo del laringoespasmo, pero ninguna de ellas es completamente eficaz. Debido a su gravedad, se hace necesario realizar más estudios con un enfoque en las medidas de prevención de esa complicación.
