title: An analysis of factors influencing postanesthesia recovery after pediatric ambulatory tonsillectomy and adenoidectomy.
abstract: BACKGROUND
  Many factors contribute to prolonged length of stay (LOS) for pediatric patients in the postanesthesia care unit (PACU). We designed this prospective study to identify the pre- and postoperative factors that prolong LOS.
  
  
  METHODS
  We studied 166 children, aged 1-18 yr, who underwent tonsillectomy and adenoidectomy or tonsillectomy and adenoidectomy, and bilateral myringotomy with tube insertion under general anesthesia. The primary outcome measure was the time spent in the PACU until predetermined discharge criteria were met.
  
  
  RESULTS
  The number of episodes of postoperative nausea and vomiting, patient age, and number of oxygen desaturations contributed significantly (P < 0.05) to prolonged LOS. Each episode of postoperative nausea and vomiting (P < 0.05) or oxygen desaturation to <95% (P < 0.05) increased the patient's LOS by 0.5 h. History of upper respiratory tract infection, emergence agitation, and parental anxiety did not significantly predict increased LOS.
  
  
  CONCLUSIONS
  This investigation is the first composite view of LOS in pediatric patients. The significance of identifying patients at risk of prolonged LOS prior to anesthesia is of use not only in allocating PACU resource and staffing needs, but also for improving quality of care and ensuring a minimally traumatic anesthetic experience for our pediatric patients and their families.
