Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
In the group T and group T/S, propofol and remifentanil will be administered to end organ concentrations of 5.0 microg ml-1 and 4.0 ng ml-1, respectively, using a target-controlled infusion (TCI) pump (Orchestra, Fresenius Vial, France) from induction of anesthesia.
In the group T/S, 30 minutes before induction of one lung ventilation, total intravenous anesthesia(TIVA) will be stopped and replaced by 2 vol% sevoflurane. Namely, group T/S will receive propofol and remifentanil, followed by 30 min sevoflurane inhalation, and then TIVA again during one lung ventilation.
Intervention code [1] 256499 0
Treatment: Drugs
Comparator / control treatment
Patients will be randomly assigned to 3 groups. One group will receive inhalational anesthesia with 2 vol% sevoflurane throughout the operation (group S), another group will receive total intravenous anesthesia (TIVA) with propofol 5 microgml-1 and remifentanil 4.0 ng ml-1 throughout the operation (group T) and the other group will receive TIVA and then shift to 2 vol% sevoflurane inhalation anesthesia for 30 minute before one lung ventilation, then receive TIVA again (group T/S).

Summary
Brief summary
Pulmonary complication after one lung ventilation (OLV) is one of serious complications after transthoracic esophagectomy (TTE). The authors designed this study to investigate that the preconditioning of volatile anesthetics could decrease the production of pro-inflammatory cytokines or oxygen free radicals and decrease the development of pulmonary complications in the patients undergoing TTE. Forty-five adults undergoing TTE with OLV will be randomly assigned to receive sevoflurane anaesthesia (group S), total intravenous anaesthesia (TIVA) using propofol with remifentanil (group T), or sevoflurane preconditioning group (group T/S).The concentrations of plasma interleukin-6 (IL-6) and plasma malondialdehyde (MDA) will be assessed before and after OLV as the primary endpoint. The clinical outcome between group S and group T will be compared as the secondary endpoint.
