Abstract
Perioperative respiratory adverse events are the most common cause of critical events in children undergoing anesthesia and surgery. While many risk factors remain unmodifiable, there are numerous anesthetic management decisions which can impact the incidence and impact of these events, especially in at-risk children. Ongoing research continues to improve our understanding of both the influence of risk factors and the effect of specific interventions. This review discusses anesthesia risk factors and outlines strategies to reduce the rate and impact of perioperative respiratory adverse events with a chronologic based inquiry into anesthetic management decisions through the perioperative period from premedication to postoperative disposition.

Anesth Essays Res 2021; 15:133-137. [PMID: 34667360 PMCID: PMC8462424 DOI: 10.4103/aer.aer_78_21] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2021] [Revised: 06/10/2021] [Accepted: 06/10/2021] [Indexed: 01/25/2023] Open
Abstract
Background: Traditional extubation often leads to bucking, coughing, and undesirable hemodynamic changes. Extubation just before administering reversal could reduce force of coughing, bucking and may provide better extubation conditions. Aim of Study: The aim of the study was to assess the incidence of bucking with extubation just before administering reversal of neuromuscular blockade compared to traditional technique of awake extubation. Incidence of coughing during extubation, vomiting/regurgitation, aspiration, hemodynamic changes, postoperative bleeding, and extubation conditions were also assessed. Settings and Design: This was a prospective randomized study conducted in a tertiary care institute. Subjects and Methods: Forty patients were allocated into two equal groups. In Group E, at the end of surgery, extubation was performed and reversal was administered after extubation. In Group L, reversal was given and patients were extubated in the traditional way. Quality of extubation was assessed using extubation quality score. Statistical Tests Used: Pearson Chi-square test, Fisher's exact test, and independent sample t-test. Results: Group E showed significantly lower incidence of bucking (15% vs. 65%) and coughing (10% vs. 45%). Incidences of desaturation and regurgitation/aspiration were comparable. In Group E, 85% of patients did not cough during extubation compared to 50% in Group L. Extubation quality was significantly better in Group E. Although extubation time was significantly shorter in Group E, recovery time was comparable in both groups. Conclusion: Extubation just before reversal of neuromuscular blockade resulted in lesser incidence of bucking and coughing during extubation with lesser postoperative bleeding compared to traditional technique of awake extubation without added risks of regurgitation, aspiration, or delayed recovery.

J Clin Med 2018; 7:jcm7100353. [PMID: 30322192 PMCID: PMC6210687 DOI: 10.3390/jcm7100353] [Citation(s) in RCA: 25] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2018] [Revised: 10/10/2018] [Accepted: 10/12/2018] [Indexed: 12/24/2022] Open
Abstract
The purpose of this study was to compare the incidence of airway complications between extubation under deep anesthesia (deep extubation) and extubation when fully awake (awake extubation) in pediatric patients after general anesthesia. A systematic review was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta Analyses (PRISMA) statement standards. The review protocol was registered with the International Prospective Register of Systematic Reviews (registration number: CRD 42018090172). Electronic databases were searched, without discrimination of publication year and language, to identify all randomized controlled trials investigating airway complications following deep or awake extubation after general anesthesia. The Cochrane tool was used to assess the risk of bias of trials. Randomized trials investigating airway complications of deep extubation compared with awake extubation after general anesthesia with an endotracheal tube and laryngeal mask airway (LMA) were sought. Overall airway complications, airway obstruction, cough, desaturation, laryngospasm and breath holding were analyzed using random-effect modelling. The odds ratio was used for these incidence variables. Seventeen randomized trials were identified, and a total of 1881 pediatric patients were enrolled. The analyses indicated deep extubation reduces the risk of overall airway complications (odds ratio (OR) 0.56, 95% confidence interval (CI) 0.33–0.96, p = 0.04), cough (OR 0.30, 95% CI 0.12–0.72, p = 0.007) and desaturation (OR 0.49, 95% CI 0.25–0.95, p = 0.04) in children after general anesthesia. However, deep extubation increased the risk of airway obstruction compared with awake extubation (OR 3.38 CI 1.69–6.73, p = 0.0005). No difference was observed in the incidence of laryngospasm and breath-holding between the two groups regardless of airway device. The result of this analysis indicates that deep extubation may decrease the risk of overall airway complications including cough and desaturation but may increase airway obstruction compared with awake extubation in pediatric patients after general anesthesia. Therefore, deep extubation may be recommended in pediatric patients to minimize overall airway complications except airway obstruction and the clinicians may choose the method of extubation according to the risk of airway complications of pediatric patients.

Abstract
BACKGROUND An important step toward improvement of the conduct of pediatric clinical research is the standardization of the ages of children to be included in pediatric trials and the optimal age-subgroups to be analyzed. METHODS We set out to evaluate empirically the age ranges of children, and age-subgroup analyses thereof, reported in recent pediatric randomized clinical trials (RCTs) and meta-analyses. First, we screened 24 RCTs published in Pediatrics during the first 6 months of 2011; second, we screened 188 pediatric RCTs published in 2007 in the Cochrane Central Register of Controlled Trials; third, we screened 48 pediatric meta-analyses published in the Cochrane Database of Systematic Reviews in 2011. We extracted information on age ranges and age-subgroups considered and age-subgroup differences reported. RESULTS The age range of children in RCTs published in Pediatrics varied from 0.1 to 17.5 years (median age: 5; interquartile range: 1.8-10.2) and only 25% of those presented age-subgroup analyses. Large variability was also detected for age ranges in 188 RCTs from the Cochrane Central Register of Controlled Trials, and only 28 of those analyzed age-subgroups. Moreover, only 11 of 48 meta-analyses had age-subgroup analyses, and in 6 of those, only different studies were included. Furthermore, most of these observed differences were not beyond chance. CONCLUSIONS We observed large variability in the age ranges and age-subgroups of children included in recent pediatric trials and meta-analyses. Despite the limited available data, some age-subgroup differences were noted. The rationale for the selection of particular age-subgroups deserves further study.

Abstract
Background An anesthetic state can reduce adverse airway reaction during laryngeal mask airway (LMA) removal in children. However, the anesthetic state has risks of upper airway obstruction or delayed emergence; so possibly less anesthetic depth is advisable. Caudal analgesia reduces the requirement of anesthetic agents for sedation or anesthesia; it is expected to reduce the sevoflurane requirement for LMA removal. Therefore, we determined the EC50 of sevoflurane for LMA removal with caudal analgesia and compared that to the EC50 without caudal analgesia. Methods Forty-three unpremedicated children aged 1 to 6 yr were enrolled. They were allocated to receive or not to receive caudal block according to their parents' consent. General anesthesia were induced and maintained with sevoflurane and oxygen in air. EC50 of sevoflurane for a smooth LMA removal with and without caudal analgesia were estimated by the Dixon up-and-down method. The LMA was removed when predetermined end-tidal sevoflurane concentration was achieved, and the sevoflurane concentration of a subsequent patient was determined by the success or failure of the previous patient with 0.2% as the step size; success was defined by the absence of an adverse airway reaction during and after LMA removal. EC50 of sevoflurane with caudal block, and that without caudal block, were compared by a rank-sum test. Results The EC50 of sevoflurane to achieve successful LMA removal in children with caudal block was 1.47%; 1.81% without caudal block. The EC50 were significantly different between the two groups (P < 0.001). Conclusions Caudal analgesia significantly reduced the sevoflurane concentration for a smooth LMA removal in anesthetized children.

Abstract
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.
