摘要

导言:尽管全球在术前容量优化方面取得了进步,但低血容量仍被认为是诱发术后低血压(PIH)的常见风险因素。正确评估全身麻醉患者的体液状况仍是麻醉医师面临的一大挑战。生物阻抗分析(BIA)是一种灵敏的方法,可以检测亚临床变化,从而客观评估患者的体液状况。本研究的主要目的是确定术前 BIA 评估的体液状态与 PIH 之间的相关性:这是一项观察性单中心研究,研究对象包括接受择期手术的患者。我们将 PIH 定义为手术切口前麻醉诱导和气管插管后 10 分钟内出现的血压下降。我们对 BIA 评估、患者麻醉前和术前准备、麻醉技术和麻醉监测进行了标准化:我们的研究包括 115 名患者。研究对象的平均年龄为 58.1 岁,总水量和细胞内水量的中位值分别为 35.1 升和 19.3 升。在单变量和多变量分析中,只有体内总水分和细胞内水分与 PIH 的不同定义有关。BIA得出的任何体液状态参数与PIH持续时间之间均无相关性:我们的研究表明,在择期手术中,生物阻抗可检测出与 PIH 相关的亚临床体液参数。

Correlations between preoperative fluid status assessed by bioimpedance analysis and hypotension during anaesthesia induction.

Introduction: Hypovolaemia is presumed to be a common risk factor of postinduction hypotension (PIH), despite worldwide improvement in preoperative volume optimization. Correct assessment of fluid status in patients undergoing general anaesthesia remains a major challenge for anaesthesiologists. Bioimpedance analysis (BIA) is a sensitive method that allows objective assessment of patient fluid status as it can detect subclinical changes. The study's main purpose was to determine the correlation between the preoperative BIA assessed fluid status and PIH.

Material and methods: This was an observational single centre study that included patients undergoing elective surgery. We defined PIH as the blood pressure decrease occurring during the first 10 minutes after induction of anaesthesia and orotracheal intubation before surgical incision. We standardized BIA evaluation, patient pre anaesthetic and preoperative preparation, technique and monitoring of anaesthesia.

Results: Our study included 115 patients. The mean age of the population was 58.1 years and the median values for total and intracellular water were 35.1 L and 19.3 L, respectively. In the univariable and multivariable analysis, only total body and intracellular water were associated with different definitions of PIH. There was no correlation between any of the BIA-derived parameters of fluid status and the duration of PIH.

Conclusions: Our study shows that in elective surgery, bioimpedance could detect subtle, subclinical fluid parameters that are associated with PIH.
