Clinical research of postoperative quality of recovery scale for analysis of emergence agitation in patients with general anesthesia

Objective To analyze the warning indicators of emergence agitation (EA) after general anesthesia with the use of postoperative quality of recovery scale (PQRS).Methods A total of 369 patients undergoing non cardiac or brain surgery were enrolled. All subjects were assessed by PQRS on their physiological, nociceptive, emotional, activities of daily living and cognitive performance at day 1 before surgery and 15-40 min (emergence period)after extubation. Univariate analysis was performed to those relative factors with EA, and sieved meaningful measures to carry on multivariate non-conditional logistic regression analysis.Results Emergence agitation occurred in 85 patients with the incidence of 23.04%. Logistic regression analysis results indicated that the risk factors of EA from high to low were poorer consciousness state (OR 3.99,95%CI 2.06-7.77), preoperative anxiety (OR 2.71,95%CI 1.52-4.80), poorer airway maintenance (OR 2.19,95%CI 1.04-4.62), male gender(OR 2.02,95%CI 1.15-3.57), hypoxemia (OR 1.82,95%CI 1.04-3.19), less than 45 years of age (OR 1.68,95%CI 1.16-2.44) and nocioceptive pain (OR 1.53,95%CI 1.07-2.18).Conclusion Combined clinical comprehensive results of PQRS with statistical analysis to get a conclusion, young (45 yr) male patients, preoperative anxiety, postoperative poorer consciousness state, poorer airway maintenance, hypoxia and nociceptive pain are important warning indicators of emergence agitation.
