Introduction: As tonsillectomy operations are done in vicinity of airways, two important purposes in anesthesia are decreasing bleeding and recovery time. Because of common use of Halothane and its reported side effects, we managed a study for comparing these two factors in two methods of anesthesia with or without Halothane. Materials and Methods: In a single blinded clinical trial, 140 (4-12 years old) children undergoing tonsillectomy, were randomly allocated in two equal groups. In the control group maintenance was done with Halothane-N2O 50% but in the case group without Halothane plus hyperventilation (Liverpool technique). Bleeding volume was estimated according to preoperative and 6 hour's postoperative hematocrit. Recovery time was recorded in minutes. Data was ahalyzed using Mann-Whitney U, T, Leven and K-S tests. Results: There was not any significant difference in sex, age, and weight and operation duration in the two groups. Mean recovery time in the case group was 7.87 minutes and in the control group 15.59 minutes, which showed a significant difference (p=0.00001). Mean bleeding volume in the case group was 44.22 ml and in the control group 58.52 ml, which also showed a significant difference (p = 0.005). Conclusion: According to our study it seems that anesthesia with Halothane causes more bleeding and prolonged recovery time in comparison to Liverpool technique.
