Effects of desflurane and propofol on systemic oxygenation in patients undergoing one-lung ventilation during video-assisted thoracoscopic surgery / 中华麻醉学杂志

ABSTRACT

Objective To compare the effects of desflurane and propofol on systemic hemodynamics and arterial oxygenation undergoing one-lung ventilation (OLV) during video-assisted thoracoscopic surgery (VATS)Methods Twenty patients,ASA physical status Ⅱ or Ⅲ, scheduled for elective VATS undergoing OLV , were prospectively randomized into two groups desflurane group(group D,n=10) and propofol group (group P,n=10) Anesthesia was induced with intravenous propofol 2mg?kg -1(group P) or thiopental 5 mg?kg -1( group D) combined with intravenous fentanyl 4?g?kg -1 ,vecuronium 01mg?kg -1 and succinylcholine 100mg , and was maintained with infusion of propofol at rate of 2-8 mg? kg -1?h -1 (group P) or inhalation of desflurane 2%-4% (group D) The Carlen double-lumen endobronchial tube was intubated to ventilated mechanically with 100% oxygen MAP and HR were monitored during the entire procedures, and blood gas analysis was made before operation, 30 min following two-lung ventilation, 30 min and 60 min following OLV in both groups,respectively Results PaO 2 were decreased significantly following OLV in both groups(P005)Conclusions Desflurane can be used as safely as propofol with one-lung ventilation during video-assisted thoracoscopic surgery
