Combination of nitrous oxide and the modified inflation-deflation method for identifying the intersegmental plane in segmentectomy: A randomized controlled trial.

ABSTRACT:

Background

During thoracoscopic segmentectomy, accurately and rapidly identifying the intersegmental plane (ISP) is of great importance. This study aimed to investigate the effect and safety of a nitrous oxide (N₂ O)/oxygen (O₂ ) inspired mixture on the appearance time of the ISP (T_ISP ) via the modified inflation-deflation method.

Methods

A total of 65 participants who underwent segmentectomy were randomized into three groups: 75% N₂ O (n = 24), 50% N₂ O (n = 23) or 0% N₂ O (n = 18). The 75% N₂ O group received a gas mixture of N₂ O/O₂ (Fio₂ = 0.25), the 50% N₂ O group received N₂ O/O₂ (Fio₂ = 0.5), and the 0% N₂
