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.
