Objective The aim of this study was to compare the effects of volatile anesthetics isoflurane and sevoflurane on intraoperative and postoperative bleeding in patients who underwent tonsillectomy and adenoidectomy. Patients and methods A total of 64 children classified as American Society of Anesthesiologists class I or II, aged between 2 and 16 years, who were scheduled for tonsillectomy and adenoidectomy were included in this prospective randomized double-blind study. The patients were randomized into two groups, isoflurane group and sevoflurane group, with each including 32 patients. They received balanced general anesthesia with isoflurane concentration 1.2% or sevoflurane concentration 2%. In all patients, the amount of intraoperative blood loss in milliliters was measured by the suction bottle, as well as by weighing the used sponges for each patient. The duration of operation and recovery time were recorded. Results Isoflurane caused significantly lower amount of perioperative bleeding compared with sevoflurane (P=0.03). No significant difference was observed between the two groups in terms of age, BMI, and operation duration, Conclusion Anesthesia with isoflurane can lead to a lower amount of intraoperative bleeding compared with sevoflurane. Therefore, isoflurane may be preferred as an inhalational agent for maintenance of general anesthesia during tonsillectomy and adenoidectomy operations.
