Hypothermia is a condition characterized by a decreased body temperature. It takes place when the body is exposed to cold weather or water for a longer period of time. Different types of hypothermia include acute hypothermia, exhaustion hypothermia, and chronic hypothermia. Excessive shivering, breathing difficulty, slurred speech, confusion, drowsiness, a weak pulse, and a loss of consciousness are the symptoms related to hypothermia.
The aim of this study was to see how effective co-warming and pre-warming are at reducing the risk of intraoperative hypothermia.
A randomized, prospective, comparative clinical study was conducted in a population of 60 participants. Participants were divided into two groups. Participants in group A received pre-warming for 30 minutes at 40°C before transport to the operation theater and also received co-warming before induction of anesthesia. Group B includes those who received co-warming at 40°C from the point of induction of anesthesia.
The mean age (years) of participants in groups A and B was identified as 43.3 ± 11.84 and 45.93 ± 15.87, respectively. The majority of the participants in the study population were males in groups A and B, with 66.67% and 73.33%, respectively. The medians of core temperature and peripheral temperature at the baseline were identified as 36.80 (36.20 to 37.12) and 32.55 (32.38 to 32.72) in group A. Similarly, it was observed as 36 (35.70 to 36.20) and 32 (31.60 to 32.02) in group B. The medians of core temperature and peripheral temperature after the surgery were identified as 34.50 (34.20 to 35) and 32.65 (31.95 to 33) in group A. Similarly, it was identified as 34 (33.80 to 34.25) and 32 (32.10 to 32.25) in group B.
Our study concluded that it is important to prevent hypothermia in patients undergoing surgery under general anesthesia. Pre-operative and intraoperative warming showed a decrease in the rate of fall in core temperature. Hence, both techniques are effective in reducing hypothermia.
体温过低是一种以体温降低为特征的状况。当身体长时间暴露于寒冷天气或水中时就会发生。不同类型的体温过低包括急性体温过低、衰竭性体温过低和慢性体温过低。过度颤抖、呼吸困难、言语不清、意识混乱、嗜睡、脉搏微弱和意识丧失是与体温过低相关的症状。
本研究的目的是观察联合升温与预升温在降低术中体温过低风险方面的效果如何。
在60名参与者中进行了一项随机、前瞻性、对比临床研究。参与者被分为两组。A组参与者在被送往手术室前在40°C下预升温30分钟，并在麻醉诱导前也接受联合升温。B组包括从麻醉诱导时起在40°C下接受联合升温的参与者。
A组和B组参与者的平均年龄（岁）分别确定为43.3±11.84和45.93±15.87。研究人群中A组和B组的大多数参与者为男性，分别占66.67%和73.33%。A组基线时核心温度和外周温度的中位数分别确定为36.80（36.20至37.12）和32.55（32.38至32.72）。同样，B组观察到的分别为36（35.70至36.20）和32（31.60至32.02）。手术后A组核心温度和外周温度的中位数分别确定为34.50（34.20至35）和32.65（31.95至33）。同样，B组确定为34（33.80至34.25）和32（32.10至32.25）。
我们的研究得出结论，对于接受全身麻醉手术的患者，预防体温过低很重要。术前和术中升温显示核心温度下降速率降低。因此，这两种技术在降低体温过低方面均有效。
