Objective We report relationship between complications and predictive factors of occurrence with multivariate analysis for cases of laser treatment under general anesthesia.Study Design: Pediatric patients (330 cases, aged 1 to 15 years old) who underwent laser treatment under inpatient general anesthesia against body surface hemangiomas or melanocytosis were examined for the complications. Methods Retrospective study from medical and anesthesia records, statistical assessment was carried out using multivariate analysis by univariate and logistic regression analysis, and p value less than 0.05 was considered to be significant difference. Results Complications were confirmed in 25%, mostly due to emergence agitation from anesthesia, and no severe complications were recognized. Multivariate analysis of factors causing complications revealed a significant difference in the limbs, the Q-switched Nd: YAG laser, and the anesthesia time of 60 minutes or longer. Conclusion While the length of anesthesia time was reported as a factor of complication occurrence in the past, there has been no report on the extremity and the Q-switched Nd: YAG laser as significant complication factors.
