Abstract:
Objective The purpose of this study was to determine and compare the hemodynamic effects of desflurane and enflurane in children.Methods Twenty-eight ASA Ⅰ-Ⅱ patients, aged 1-5 years were randomly assigned to receive either desflurane (group D) or enflurane (group E) for maintenance of anesthesia.Cardiac output was continuously monitored by transesophageal Doppler (TECO1).The stroke volume index (SVI), cardiac index (CI),heart rate (HR) and blood pressure(SBP,DBP,MAP) were determined before and during inhalation of desflurane and enflurane at 0.5,1.0 and 1.5 MAC.Results At 0.5 MAC of both agents SVI, CI and HR remained unchanged, but SBP, DBP and MAP were slightly reduced as compared to the baseline values.At 1.0 MAC of desflurane CI was increased and was higher than that in the group E. SVI and HR were significantly higher in group D than those in group E at 1.0 MAC.SBP, MAP and DBP were further reduced and the magnitude of reduction was similar between both groups.At 1.5 MAC CI and SVI were unchanged in group D but greatly reduced in group E.HR increased significantly in group D but remained unchanged in group E.There was further decrease in BP in both groups but SBP and MAP decreased more markedly in group E than in group D .Conclusions Desflurane causes less hemodynamic changes in children of 1-5 years than enflurane.
