Risk factors for adverse events in children with colds emerging from anesthesia: a logistic regression

PEDIATRIC ANESTHESIA, Issue 2 2007
J. RACHEL HOMER BM BCh
Summary Background:, Recent upper respiratory infection (URI) in children increases respiratory adverse events following anesthesia for elective surgery. The increased risk continues weeks after resolution of acute URI symptoms. Few systematic analyses have explored specific risk factors. This logistic regression explores the relationship between preoperative URI symptoms and adverse events during emergence from anesthesia. Methods:, Data were combined from control groups of several prospective observational and interventional studies in elective pediatric anesthesia in a tertiary care pediatric hospital. In each study, a blinded observer, distinct from the anesthesia care team, prospectively recorded the presence of stridor, oxygen desaturations (and their duration), coughing and laryngospasm. Parents were subsequently asked about the presence of 10 cold symptoms during the 6 weeks prior to operation. Results:, Our model, based on a dataset of 335 patients, did not demonstrate an association between any particular symptoms and the rate of respiratory adverse events during emergence from anesthesia, with the exception of low-grade fever which appeared to be mildly protective. Respiratory adverse events were affected by the airway management technique (device used and timing of extubation), and adverse events were increased if peak URI symptoms had occurred within the preceding 4 weeks. Conclusions:, Specific preoperative symptoms were not useful in predicting respiratory adverse events during emergence from anesthesia. [source]

Anticholinergics and Ketamine Sedation in Children: A Secondary Analysis of Atropine Versus Glycopyrrolate

ACADEMIC EMERGENCY MEDICINE, Issue 2 2010
Steven M. Green MD
Abstract Objectives:, Adjunctive anticholinergics are commonly administered during emergency department (ED) ketamine sedation in children under the presumption that drying oral secretions should decrease the likelihood of airway and respiratory adverse events. Pharmacologic considerations suggest that glycopyrrolate might exhibit a superior adverse effect profile to atropine. The authors contrasted the adverse events noted with use of each of these anticholinergics in a large multicenter observational database of ketamine sedations. Methods:, This was a secondary analysis of an observational database of 8,282 ED ketamine sedations assembled from 32 prior series. The authors compared the relative incidence of six adverse events (airway and respiratory adverse events, laryngospasm, apnea, emesis, recovery agitation, and clinically important recovery agitation) between children who received coadministered atropine, glycopyrrolate, or no anticholinergic. Multivariable analysis using the specific anticholinergic as a covariate was performed, while controlling for other known predictors. Results:, Atropine was associated with less vomiting (5.3%) than either glycopyrrolate (10.7%) or no anticholinergic (11.4%) in both unadjusted and multivariable analyses. Glycopyrrolate was associated with significantly more airway and respiratory adverse events (6.4%) than either atropine (3.3%) or no anticholinergic (3.0%) and similarly more clinically important recovery agitation (2.1% vs. 1.2 and 1.3%). There were, however, no differences noted in odds of laryngospasm and apnea. Conclusions:, This secondary analysis unexpectedly found that the coadministered anticholinergic atropine exhibited a superior adverse event profile to glycopyrrolate during ketamine sedation. Any such advantage requires confirmation in a separate trial; however, our data cast doubt on the traditional premise that glycopyrrolate might be superior. Further, neither anticholinergic showed efficacy in decreasing airway and respiratory adverse events.
