To determine the effect of warming arthroscopic irrigation solution on core body temperature during hip arthroscopic surgery in patients with femoroacetabular impingement.
An analytical, prospective, observational study was performed in a cohort of 166 consecutive patients. All patients underwent hip arthroscopy for treatment of femoroacetabular impingement. Two groups were studied: patients operated on with arthroscopic irrigation solution warmed up to 32°C ± 2°C (89.6°F ± 3.6°F) and a control group comprising patients operated on with irrigation solution used at room temperature. Relevant information was collected regarding the patients (age, sex, body mass index, and blood pressure) and the procedure (volume and temperature of saline solution, pressure of fluid pump, surgery time, and room temperature). Corresponding statistical analysis was performed with STATA 11.0 (StataCorp, College Station, TX), by use of descriptive statistics, parametric and nonparametric tests, and a generalized estimating equation model for repeated measurements.
Both groups were comparable in terms of age, sex, systolic and diastolic blood pressure, body mass index, volume of irrigation solution used, and room temperature. The mean age of the cohort was 33 years (range, 14 to 60 years); mean body mass index, 23.7 kg/m(2) (range, 17.2 to 34 kg/m(2)); mean volume of irrigation solution, 26 L (range, 12 to 39 L); mean systolic blood pressure, 97 mm Hg; mean diastolic blood pressure, 51 mm Hg; and mean surgical time, 110 minutes. A decrease in core body temperature by 0.5°C (0.9°F) or greater occurred during the course of surgery in 66% of patients in the control group versus 28% in the warmed-solution group (P < .001). At least 1 core body temperature measurement of less than 36°C (96.8°F) was recorded in 48% of patients in the control group versus 14% in the warmed-solution group (P < .001). The trend toward a decrease in core body temperature was 4 times greater in the control group than in the warmed-solution group (P < .001).
Use of arthroscopic irrigation solution warmed up to 32°C (89.6°F) reduces the risk of a decrease in core body temperature during hip arthroscopy in patients with femoroacetabular impingement.
Level II, analytical, prospective, comparative study in a cohort of consecutive patients.
确定髋关节镜检查术中加热关节灌洗液对股骨髋臼撞击症患者核心体温的影响。
对 166 例连续患者进行了分析性、前瞻性、观察性研究。所有患者均因股骨髋臼撞击症接受髋关节镜手术治疗。研究了两组患者：一组使用温度加热至 32°C ± 2°C（89.6°F ± 3.6°F）的关节镜灌洗液进行手术，另一组为室温下使用灌洗液的对照组。收集了与患者（年龄、性别、体重指数和血压）和手术（盐水的体积和温度、流体泵的压力、手术时间和室温）相关的信息。使用 STATA 11.0（StataCorp，College Station，TX）进行相应的统计分析，采用描述性统计、参数和非参数检验以及重复测量的广义估计方程模型。
两组在年龄、性别、收缩压和舒张压、体重指数、灌洗液用量和室温方面均具有可比性。队列的平均年龄为 33 岁（范围 14 至 60 岁）；平均体重指数为 23.7kg/m²（范围 17.2 至 34kg/m²）；平均灌洗液用量为 26L（范围 12 至 39L）；平均收缩压为 97mmHg；平均舒张压为 51mmHg；平均手术时间为 110 分钟。在对照组中，66%的患者在手术过程中核心体温下降 0.5°C（0.9°F）或以上，而在加热溶液组中则为 28%（P <.001）。在对照组中，有 48%的患者至少有一次核心体温测量值低于 36°C（96.8°F），而在加热溶液组中则为 14%（P <.001）。对照组核心体温下降的趋势比加热溶液组高 4 倍（P <.001）。
使用加热至 32°C（89.6°F）的关节镜灌洗液可降低股骨髋臼撞击症患者髋关节镜检查时核心体温下降的风险。
队列连续患者的分析性、前瞻性、比较性研究，II 级。
