研究目的:

本研究拟通过一项前瞻性随机对照试验,评估不同PEEP策略对腹腔镜结直肠癌手术患者呼吸道黏液纤毛清除功能的影响,旨在从功能学层面揭示PEEP的肺保护机制,并为建立个体化通气方案提供理论支持。  

Objectives of Study:

This study, a prospective, randomized, controlled trial, aimed to evaluate the effects of different positive end-expiratory pressure (PEEP) strategies on mucociliary clearance in patients undergoing laparoscopic colorectal cancer surgery. The aim was to elucidate the lung-protective mechanisms of PEEP from a functional perspective and provide theoretical support for the development of personalized ventilation strategies.

随机方法(请说明由何人用什么方法产生随机序列):

采用计算机随机数字表法将入选患者随机分为A、B、C三组,A组:低PEEP组(PEEP=0cmH2O)、B组:中PEEP组(PEEP=5cmH2O)、C组:高PEEP组(PEEP=10cmH2O)。

Randomization Procedure (please state who generates the random number sequence and by what method):

Patients selected were randomly divided into three groups (A, B, and C) using a computer-generated random number table. Group A was the low PEEP group (PEEP = 0 cmH2O), Group B was the moderate PEEP group (PEEP = 5 cmH2O), and Group C was the high PEEP group (PEEP = 10 cmH2O).

盲法:

该实验采用“评估者盲法”(单盲)法,所有干预方案均采用由计算机随机分为的编号为1至75的不透明信封进行存储,每件信封里的PEEP水平随机分为0cmH2O、5cmH2O和10cmH2O其中一种,编号顺序与生成顺序一致。由一位对研究情况知情的麻醉医师拆封信封并确定PEEP水平。纤维支气管镜检查由另一位资深且经验丰富的麻醉医师执行,该医师对研究情况不知情。记录数据的护士也对研究情况不知情。在进行支气管镜检查时,麻醉机的参数被不透明布覆盖,以确保操作者对研究情况不知情。

Blinding:

This experiment employed an 'assessor-blinded' (single-blind) method. All intervention protocols were stored in opaque envelopes numbered 1 to 75, which were randomly assigned by computer. Each envelope contained one of three randomly determined PEEP levels: 0 cmH2O, 5 cmH2O, or 10 cmH2O, with the envelope numbering matching the order of generation. A single anesthesiologist, who was aware of the study details, opened the envelopes to determine the PEEP level. The fiber-optic bronchoscopy was performed by another senior and experienced anesthesiologist who was unaware of the study details. The nurse recording the data was also unaware of the study details. During the bronchoscopy, the parameters of the anesthesia machine were covered with an opaque cloth to ensure the operator remained unaware of the study details.
