摘要
目的
2
探究妇科手术患者中低体温持续时间与术后并发症之间的关系。
方法
2
连续纳入2020年10月至2022年1月我院择期妇科手术的患者，持续监测术中核心体温变化，追踪术后早期并发症。通过线性回归模型控制潜在的混杂因素，分析术后并发症与术中低体温持续时间、最低体温小于36°C以及进入PACU或ICU时低体温状态的关联。此外，使用累积概率散点图和移动平均序列探索低体温持续时间与术后并发症率之间存在的潜在拐点。
结果
2
研究共纳入370例患者，其中193例（52.2%）出现低体温，177例（47.8%）体温正常。在这些患者中，共有92例（24.9%）发生了并发症。低体温持续时间（每增加1分钟调整后
OR
值：1.003，95%
C
I： 1.000 - 1.006，
P
= 0.047）和进入PACU或ICU时的低体温状态（调整后
OR
值：1.980，95% CI： 1.135 - 3.454，
P
= 0.016）与术后早期并发症相关。值得注意的是，随着低体温持续时间的增加，术后并发症的累积发生率呈上升趋势，且在120分钟处观察到一个潜在的拐点。
结论
2
在妇科手术中，低体温的持续时间以及进入PACU或ICU时的低体温状态与术后并发症有关。尽量缩短低体温的持续时间在临床上可能是有意义的。
Abstract
Objective
2
To investigate the relationship between hypothermia duration and postoperative complications in patients undergoing gynecological surgery.
Methods
2
Patients who underwent elective gynecological surgery at our hospital were consecutively enrolled between October 2020 and January 2022. Core temperature was continuously monitored intraoperatively
and early postoperative complications were collected. By adjusting the logistic regression model for potential confounding factors
the association of postoperative complications with the duration of hypothermia
the lowest body temperature below 36°C
and the hypothermia upon admission to postanesthesia care unit (PACU) or intensive care unit (ICU) were analyzed. Additionally
the potential inflection point in the relationship between the duration of hypothermia and the risk of postoperative complications was explored by using cumulative probability scatter plots and moving average sequences.
Results
2
The study included 370 patients
with 193 (52.2%) experiencing hypothermia and 177 (47.8%) not. Among them
92 (24.9%) developed complications. The duration of hypothermia (adjusted odds ratio [
OR
]
for each one-minute increase: 1.003; 95% confidence interval [
CI
]
: 1.000-1.006
P
=0.047) and hypothermia upon admission to PACU or ICU (adjusted
OR
: 1.980; 95%
CI
: 1.135-3.454
P
=0.016) were associated with early postoperative complications. Notably
the cumulative incidence of postoperative complications tended to rise as the duration of hypothermia increased
with a potential inflection point observed at 120 minutes.
Conclusions
2
In gynecological surgery
the duration of hypothermia as well as hypothermia upon admission to PACU or ICU are associated with postoperative complications. Minimizing the duration of hypothermia may be clinically beneficial.
