RESUMEN
BACKGROUND: Laryngospasm is sustained closure of the airways and can be a life-threatening condition. Magnesium sulphate is postulated to reduce the incidence of laryngospasm if administered peri-operatively. This systematic review and meta-analysis was performed to assess the efficacy of magnesium sulphate in preventing peri-operative laryngospasm in paediatric patients undergoing non-cardiac surgery. METHODS: Four databases and a trial registry were searched. Inclusion criteria were paediatric patients undergoing general anaesthesia. Exclusion criteria were patients who underwent cardiopulmonary bypass during surgery. The intervention of interest was the peri-operative administration of magnesium sulphate. The intervention was compared to either a placebo or other pharmacological agent. The primary outcome was the incidence of laryngospasm. A meta-analysis of all studies was performed. Sub-group analysis was subsequently performed. RESULTS: A total of 953 patients from 13 trials were included in this study. Nine RCTs administered magnesium intravenously and 4 RCTs administered magnesium locally. Laryngospasm rates were 6% lower in the magnesium group (OR 0.48 [95% CI 0.25-0.96], p = 0.04) compared to control in the pooled data. Subgroup analysis showed laryngospasm rates were lower by 12.5% (Odds Ratio 0.26 [CI 0.09-0.76], p = 0.01) in the local magnesium group. Subgroup analysis of studies that only administered intravenous magnesium did not show a statistically significant difference in the incidence of laryngospasm (OR 0.73 [95% CI 0.33-1.63], p = 0.44). CONCLUSIONS: This review shows a potential role for magnesium in the prevention of laryngospasm in paediatric patients undergoing general anaesthesia. There is a correlation between local administration of magnesium and reduction in laryngospasm rates. Further studies are required to assess the efficacy of intravenous magnesium in prevention of laryngospasm.

RESUMEN
Background and Aims: Postextubation airway complications are more common in paediatric patients than in adults. Intravenous lignocaine effectively prevents extubation response; however, data on using intracuff lignocaine in microcuff endotracheal tubes is scarce. The primary aim of this study was to compare the incidence of postextubation cough between intracuff lignocaine and intracuff air in the paediatric population during tracheal extubation. Methods: This randomised controlled study was conducted in 120 paediatric patients aged 1 month to 12 years who were scheduled to undergo surgeries under general anaesthesia. They were randomised to Group C (intracuff air) and Group L (intracuff 2% lignocaine). After administering general anaesthesia, the airway was secured with an age-appropriate microcuff endotracheal tube. According to groups, the cuff was inflated with air or lignocaine to achieve a cuff pressure of 10 cm H2O. Incidences of cough, desaturation, laryngospasm, apnoea and haemodynamic changes were recorded after tracheal extubation. Categorical variables were compared using the Chi-square or Fisher's exact test, and continuous variables were compared using the Student's t-test or Mann-Whitney U test. Intergroup differences between the variables were analysed by a two-way repeated measure analysis of variance. Results: The incidence of postextubation cough was significantly higher in Group C [17 (28.3%) (confidence interval {CI} = 17.4-41.4)] when compared to Group L [8 (13.3%) (CI = 5.9-24.6)], with P = 0.043. One patient in Group C had laryngospasm compared to none in Group L. In Group C, there was also a significant increase in heart rate at all time points (1-5 min after extubation) from the baseline, and this increase was also significantly higher when compared to Group L (P < 0.05). Conclusion: The incidence of postextubation cough was significantly lower with intracuff lignocaine compared to that with intracuff air in paediatric patients.
RESUMEN
Periorbital emphysema is a rare complication following functional endoscopic sinus surgery (FESS) with potential sight-threatening consequences. We present a case of an eight-year-old male who developed periorbital emphysema after FESS for allergic fungal sinusitis. Prompt diagnosis was made using point-of-care ultrasound (POCUS), facilitating timely intervention and conservative management. This case underscores the importance of perioperative imaging to identify lamina papyracea abnormalities, smooth extubation to prevent complications, and the innovative use of POCUS in diagnosing perioperative orbital emphysema and managing it conservatively while examining the eye at regular intervals. These findings highlight the significance of vigilance during FESS procedures and the utility of POCUS in diagnosing and managing rare perioperative complications.
RESUMEN
Morvan syndrome is a rare condition distinguished by hyperactivity within the central, autonomic, and peripheral nervous systems. Due to the limited number of cases, this presents clinical challenges stemming from the scarcity of published literature. We present a successful anesthetic approach for a patient diagnosed with Morvan syndrome scheduled for elective major intra-thoracic surgery to remove metastases from a thymoma. The patient had previously undergone thymectomy, with the syndrome being diagnosed only one year after the surgery. Additionally, we conducted a literature review on the anesthetic management of this condition.
RESUMEN
Negative pressure pulmonary edema (NPPE), also known as post-obstructive pulmonary edema, is a rare and life-threatening condition. It occurs when a person breathes against an obstructed glottis, causing negative thoracic pressure in the lungs. This negative pressure can lead to fluid accumulation in the lungs, resulting in pulmonary edema. The obstructed glottis might be caused by laryngospasm, which occurs when the muscles around the larynx involuntarily spasm and can lead to complete upper airway occlusion. This report shares the case of a 33-year-old woman hospitalized for periapical dental abscess, facial swelling, and shortness of breath. The patient exhibited signs of poor oral hygiene. After the exacerbation of her symptoms, she showed signs of asphyxia and decreased oxygen saturation, which led to her intubation. Imaging revealed bilateral pleural effusion and patchy ground glass opacities favoring NPPE. After three days of treatment with diuretics and other conservative measures, her condition was alleviated, and she was extubated. Laryngospasm in the presence of a dental abscess is uncommon. Identification of imaging favoring NPPE in this setting is even more rare. In cases of laryngospasm, prompt intubation is crucial. Therapy with diuretics and other conservative measures can effectively treat NPPE following laryngospasm.
RESUMEN
We present a case in which intramuscular rocuronium was used successfully to treat laryngospasm in a pediatric patient. An 11-month-old infant weighing 9.7 kg was scheduled for an elective laparoscopic inguinal hernia repair surgery. Anesthesia was induced with oxygen, nitrous oxide, and sevoflurane. After loss of consciousness, mask ventilation became impossible, and laryngospasm was suspected. Intravenous access was attempted without success; as there was no immediate access to succinylcholine, rocuronium 10 mg (1.0 mg/kg) was injected intramuscularly into the vastus lateralis muscle. We were able to mask-ventilate the patient within one minute of intramuscular rocuronium, followed by successful endotracheal intubation with a video laryngoscope. The duration of hypoxia (saturation of peripheral oxygen (SpO2) < 90%) was approximately two minutes, and the patient's lowest oxygen saturation during induction was 76%. At the end of the surgery, the patient was uneventfully extubated. We conclude that intramuscular rocuronium may provide an alternative treatment for laryngospasm in pediatric patients with no intravenous access and no availability of succinylcholine.
RESUMEN
Introduction: Ketamine and propofol are commonly used agents for sedation in the pediatric emergency department (PED). While these medications routinely provide safe sedations, there are side effects providers should be able to recognize and manage. Currently, no pediatric sedation simulations exist in the literature. Methods: We created two sedation simulation cases for learners, including pediatric emergency medicine (PEM) fellows, working in the PED: case 1, a 12-year-old male with a shoulder dislocation requiring reduction under propofol sedation, and case 2, a forearm fracture requiring reduction under ketamine sedation. Learner actions included setting up equipment for sedations, dosing medications correctly, and managing complications. Additionally, in case 2, learners assigned an American Society of Anesthesiologists classification and selected the appropriate candidate for PED sedation from amongst three patients. A debrief followed the cases. Next, a didactic presentation reinforced concepts discussed in the debrief. Participants then completed an evaluation of the simulation. Results: Fifty-eight emergency medicine residents and PEM fellows across four sites at three institutions participated. Participants scored the simulations and the debriefing session on a 5-point Likert scale. Learners rated the scenario as clinically relevant (M = 4.37) and effective at improving their comfort level in caring for critically ill patients (M = 4.36). Learners felt the debrief provided valuable learning (M = 4.40) and was a safe learning environment (M = 4.50). Discussion: These cases can be utilized as resources for learners in any emergency department and can be tailored to any training background of learner providing sedation.

Respiratory complications are the most frequent incidents in pediatric anesthesia after cardiac events. The pediatric respiratory physiology and airway anatomy are responsible for the particular respiratory vulnerability in this stage of life. This article explains the aspects of pulmonary embryogenesis relevant for anesthesia and their impact on the respiration of preterm infants and neonates. The respiratory distress syndrome and bronchopulmonary dysplasia are highlighted as well as the predisposition to apnea of preterm infants and neonates. Due to the anatomical characteristics, the low size ratios and the significantly shorter apnea tolerance, airway management in children frequently represents a challenge. This article gives useful assistance and provides an overview of formulas for calculating the appropriate tube size and depth of insertion. Finally, the pathophysiology and adequate treatment of laryngospasm are explained.

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.

RESUMEN
INTRODUCTION: Utilizing laryngeal mask airways to maintain patients' airways is advantageous because it enables the anesthesiologist to keep the patient spontaneously inhaling and is less traumatic to the airway than intubation. Newer designs such as the Gnana laryngeal mask airway design permit real-time suctioning while the mask is on a patient. METHODS: This is a prospective observational study of the efficacy of Gnana laryngeal airway 4 (GLA-4) in 50 patients undergoing colonoscopy. Induction and maintenance of anesthesia were provided with propofol; GLA-4 was applied to secure the airway; and correct placement was verified. RESULTS: Fifty patients were included in the study (44% female, 56% male, mean age: 56.5 years, mean BMI: 33.3). Twelve patients were assigned American Society of Anesthesiologists (ASA) class 2, and 38 were assigned ASA class 3. The first attempt of GLA-4 insertion was successful in 47 patients, and two attempts were required for the successful placement of the GLA-4 in two patients. The successful placement was not achieved in one patient. The average time to successful insertion was 27.1 ± 3.9s. The average volume of oropharyngeal secretions suctioned through the suction catheter was 9.96 ± 2.31 mL. No intraoperative or postoperative complications occurred in the 50 patients. There were no reports of sore throat, hoarseness, dysphagia, or cough immediately postop. CONCLUSION: GLA-4 can be inserted safely with adequate periglottic occlusion. This laryngeal mask is unique and desirable due to its ability to evacuate oropharyngeal secretions while in place to prevent laryngospasm. To establish the role of GLA-4 in broader clinical situations, additional clinical trials and studies are required.

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.

Anti-N-methyl-aspartate receptor encephalitis (anti-NMDARE) is a rare autoimmune panencephalitis. We report the case of a patient with anti-NMDARE with severe ictal laryngospasm. A 17-year old boy was referred to our neurological intensive care unit for refractory behavioural symptoms and cognitive decline. Brain magnetic resonance imaging was normal. Screening for antineuronal antibodies showed positive results for anti-NMDA in serum and cerebrospinal fluid,which confirmed the diagnosis of anti-NMDARE. During his admission,he developed severe ictal laryngospasm resulting in intubation, tracheostomy, and repeated courses of intravenous immunoglobulin and methylprednisolone. The patient then made an uneventful recovery and was discharged to outpatient follow-up. Our report intends to raise awareness that patients with anti-NMDARE may manifest fatal ictal laryngospasm,requiring urgent and aggressive management.

Negative pressure pulmonary edema is a rare complication of general anesthesia. This paper presents a case of acute negative pressure pulmonary edema that occurred during general anesthesia resuscitation. The patient is a young male that underwent bimaxillary surgery under general anesthesia. Laryngospasm spasm ensued after extubation. The treatment for laryngeal spasm retained the smoothness of the nasopharyngal airway, and the pulse oxygen saturation rapidly decreased after anesthesia resuscitation. Pink foam sputum was sucked out from the cavity due to respiratory shortness from mouth and nose. Highly concentrated oxygen was immediately given to assist ventilation and as a symptomatic support (diuretics, hormones), and the condition evidently improved. The diagnosis and treatment of this case suggest that when acute pulmonary edema occurs during general anesthesia resuscitation, negative pressure pulmonary edema should be highly suspected. The first line of treatment is to relieve respiratory tract obstruction. Supplying highly concentrated oxygen to assist positive pressure ventilation is an effective treatment to alleviate pulmonary edema.

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.

OBJECTIVES@#To analyze the clinical characteristics of paroxysmal laryngospasm in adult.@*METHODS@#A retrospective analysis was performed on 149 patients with paroxysmal laryngospasm in adult. All patients underwent the strobolaryngoscopy, completed the reflux symptom index (RSI) or the reflux finding score (RFS). Partial patients underwent an ambulatory 24-hour pH measurement.@*RESULTS@#Laryngospasm was diagnosed in 76 females and 73 males. The average age was 55.4±11.4. The episode time of 149 (98%) patients last from several seconds tominutes, and 139 (93.3%) episodes could have a spontaneous remission. 84 (56.4%) episodes occurred only in the daytime, 28 (18.8%) only in the nighttime. There were 45.6% over weight/obesity patients, including 40 males and 28 females. The smokers were 28.9% (43/149) including 40 males and 3 females, and the drinkers were 29.5% (44/149) with 39 males and 5 females. 76 (51.0%) patients had no induced factor, while some caused by irritable cough/bucking (53,35.6%), cold (15, 10.1%), excitant food/smell (10, 6.7%), or regurgitation (6.5, 4.0%). Strobolaryngoscopy revealed laryngopharyngeal lesions in 46.3% (69/149) patients, including the glottic lesions with 40 (26.8%), unilateral vocal fold paralysis (21, 14.1%) and supraglottic lesions (8,5.4%). RSI/RFS showed 74.5% (111/149) patients had laryngopharyngeal reflux. Two patients treated with dietary and lifestyle modifications get improved, and 15/16 of the patients responded to antireflux treatment.@*CONCLUSIONS@#Episode of paroxysmal laryngospasm occurs more in the daytime, and could have a spontaneous resolution. Paroxysmal laryngospasm is much easier to occur in the male who are overweight or obesity, or with a long-term history of smoking or drinking. Almost half of the patients have an induced factor; partial may have laryngopharyngeal lesions simultaneously. Paroxysmal laryngopharyngeal reflux may be closely related to laryngospasm.

Sleep-related laryngospasm is a rare cause of sleep-related breathing disturbance which produce stridor or interruption of airflow associated with a distinct polysomnography arousal pattern. We report a case of a sixty-five-year-old woman who was referred for awakenings with abrupt respiratory distress and fear of suffocation. A polysomnography showed a total or near-total cessation of airflow, followed by choking and stridor for several minutes with a rapid increase in heart rate. Temporary hoarseness was seen. The esophageal pH monitoring indicated acid reflux, which confirmed gastroesophageal reflux disease. The protonpump inhibitor eliminated the sleep-related laryngospasm.
