Comparison of Inhaled Anesthesia with Sevoflurane and Intravenous Anesthetics with Propofol in Children under Flexible Bronchoscopy

Abstract

Objective: Bronchoscopy is a diagnostic procedure. Due to lack of cooperation of children, pediatric bronchoscopy is necessarily accompanied by anesthesia. The most prevailing method of anesthesia in children is inhaled anesthesia, but since duration of anesthesia is long and there is involuntary respiration in this method, the amount of dispersed gas is high. The objective of this review is comparing inhaled anesthesia with sevoflurane and intravenous anesthetics with propofol in children under flexible bronchoscopy, in order to do a more appropriate and safe bronchoscopy and also to improve recovery after general anesthesia in children.

Methodology: 80 children under the age of 10 who were going under flexible bronchoscopy, were randomly divided into two groups of 40 individuals. For anesthesia of one group inhaled sevoflurane was given, and for the second group intravenous propofol was given; then in both groups changes in blood pressure, heart rate, O2 saturation t, and recovery time were recorded and compared.

Findings: There is no significant difference in three times measurement of both anesthetics. In other words the average blood pressure shows no difference after anesthesia, start of bronchoscopy, and end of bronchoscopy in both anesthetics (P-value=0.771). Moreover, no significant difference was observed in three times measurement of both anesthetics. This means that the average heart rate shows no difference after anesthesia, start of bronchoscopy, and end of bronchoscopy in both anesthetics. Furthermore, the average o2sat is different after anesthesia, start of bronchoscopy, and end of bronchoscopy in both anesthetics (P-value>0.001).
