Background: Emergence agitation (EA) is one of the most common complications after general anesthesia. The goal of this retrospective study was to determine the risk factors of EA in adult patients who underwent general anesthesia.
Methods: We retrospectively investigated the medical records of 5,358 adult patients who stayed in the postanesthesia care unit (PACU) of our hospital after general anesthesia during the 1-year period from January 2014 to December 2014. Psychological and behavioral status in the PACU was determined by the Aono four-point scale. Grade of 3 or 4 were considered as manifestations of EA. Multiple variables assessed EA risk factors.
Results: Two-hundred-forty-five patients (4.6%) developed EA. In multivariate analysis, male gender (OR = 1.626, P = 0.001), older age (OR = 1.010, P = 0.035), abdominal surgery (OR = 1.633, P = 0.002), spine surgery (OR = 1.777, P = 0.015), longer duration of anesthesia (OR = 1.002, P < 0.001), postoperative nausea and vomiting (OR = 20.164, P < 0.001) and postoperative pain (OR = 3.614, P < 0.001) were risk factors of EA.
Conclusions: Male gender and older patients were risk factors of EA after general anesthesia in adult patients. Careful attention is needed for patients who receive abdominal or spine surgery, and who receive prolonged anesthesia. Adequate postoperative analgesia and antiemetic therapy should be provided to reduce the incidence of EA.
