Close monitoring and heated irrigation fluids have been frequently used to avoid hypothermia and associated complications during hip arthroscopic surgery. Saline fluids are used extensively in hip arthroscopic surgery, but they are routinely stored at room temperature and are cooler than the patient's core temperature.
To investigate the efficacy of heated irrigation fluids to prevent hypothermia during hip arthroscopic surgery and whether the core temperature measured rectally during hip arthroscopic surgery differs from the core temperature measured at the temporal region.
Randomized controlled trial; Level of evidence, 2.
Patients who underwent hip arthroscopic surgery for the treatment of femoroacetabular impingement syndrome between 2021 and 2023 were prospectively enrolled and divided into 2 groups: those whose irrigation fluids were stored at room temperature (group 1) and those whose irrigation fluids were heated to 36°C to 38°C (group 2). A probe inserted in the rectal mucosa was used to measure the patient's body temperature every 15 minutes. The patient's temperature was also measured at the temporal region with a laser thermometer. A body temperature <36°C, detected by either method, was considered as hypothermia. The method that detected hypothermia more quickly was investigated, and the effect of the heated irrigation fluids was explored. Statistical analyses were conducted to compare temperature measurements and the incidence of hypothermia between the groups using appropriate tests for categorical and continuous variables based on the data distribution.
There were 60 patients randomized and allocated to group 1 and 56 patients to group 2. Hypothermia, defined as a temperature <36°C, occurred in 32 patients (53.3%) in group 1 and 24 patients (42.9%) in group 2. There was no difference between the groups using heated or room-temperature fluids in the onset of hypothermia ( = .425). Significantly more hypothermia cases were detected by the rectal temperature measurement than by the temporal temperature measurement (54 vs 2 patients, respectively; < .001). The rectal temperature measurement was also quicker in detecting hypothermia (69.6 ± 47.2 vs 138.2 ± 56.8 minutes, respectively; < .001).
This study demonstrates that the usage of either room-temperature or heated irrigation fluids did not influence the incidence of hypothermia. Rectal measurements of core body temperature detected hypothermia earlier during hip arthroscopic surgery.

在髋关节镜手术期间，密切监测和使用温热冲洗液常用于避免体温过低及相关并发症。生理盐水在髋关节镜手术中广泛使用，但通常在室温下储存，温度低于患者的核心体温。
探讨温热冲洗液在髋关节镜手术中预防体温过低的效果，以及髋关节镜手术期间经直肠测量的核心体温与颞部测量的核心体温是否存在差异。
随机对照试验；证据等级，2级。
前瞻性纳入2021年至2023年期间因股骨髋臼撞击综合征接受髋关节镜手术的患者，并分为两组：冲洗液在室温下储存的患者（第1组）和冲洗液加热至36°C至38°C的患者（第2组）。每隔15分钟使用插入直肠黏膜的探头测量患者体温。还使用激光温度计在颞部测量患者体温。通过任何一种方法检测到体温<36°C均被视为体温过低。研究哪种方法能更快检测到体温过低，并探讨温热冲洗液的效果。根据数据分布，使用适用于分类变量和连续变量的检验对两组间的体温测量值和体温过低发生率进行统计分析。
60例患者被随机分组并分配至第1组，56例患者分配至第2组。体温过低定义为体温<36°C，第1组有32例患者（53.3%）发生，第2组有24例患者（42.9%）发生。使用温热或室温冲洗液的两组在体温过低的发生时间上无差异（P = 0.425）。经直肠温度测量检测到的体温过低病例明显多于经颞部温度测量（分别为54例和2例；P < 0.001）。经直肠温度测量在检测体温过低方面也更快（分别为69.6±47.2分钟和138.2±56.8分钟；P < 0.001）。
本研究表明，使用室温或温热冲洗液均不影响体温过低的发生率。在髋关节镜手术期间，经直肠测量核心体温能更早检测到体温过低。
