Effect of Low Tidal Volume on Blood Loss During Laparoscopic Hepatectomy

Not Applicable

• Conditions: Blood Loss

• Registration Number: NCT03399123
• Lead Sponsor: Southwest Hospital, China

Brief Summary

To explore the effect of low tidal volume on blood loss and gas exchange during laparoscopic hepatectomy

Detailed Description

Background \& Aims:Liver cancer is an disease that threatening human health .Laparoscopic hepatectomy is more and more widely used.It is very important to reduce the bleeding during laparoscopic hepatectomy.The investigators found that low tidal volume can effectively reduce intraoperative bleeding.The aim of this study was to explore the effect of low tidal volume on blood loss and gas exchange during laparoscopic hepatectomy
