文题释义:
围术期低体温:目前尚无统一定义,一般认为是围术期因各种因素导致的中心体温低于36 ℃即可称为围术期低体温,发病率目前文献报道在20%-70%之间不等,围术期体温的降低会导致很多相应临床并发症的发生。
寒战:是骨骼肌在受到某种刺激时产生的肌纤维收缩,从而增加机体产热量并升高体温的反应,这是一种机体自我保护性应激反应,主要表现为肌痉挛和肌强直、战栗和不自主的发抖。寒战是手术后患者常见的并发症之一,目前临床报道发生率为5%-65%,寒战时肌束颤动能使患者产生不适合痛苦感并增加焦虑程度,严重者可加重病情,干扰生命体征检测,甚至导致麻醉意外。
 
 
背景:有研究指出,围术期低体温可增加凝血病、酸中毒、脑卒中、脓毒症、肺炎、心肌梗死等的发生,因此围术期监测和维持正常体温具有重要意义。
目的:为了预防围术期患者低体温,降低并发症,设计了医用碳纤维恒温加热垫。
方法:将碳纤维发热技术与医用设备标准相结合,并融入多种先进技术,该设计主要由电源控制系统、调控面板、计算机辅助电路控制系统、PWM调节及输出、数个独立加热区加热垫、温度调节及测量系统等部分构成。将郑州市第一人民医院接受硬膜外麻醉的200例手术患者随机分2组,每组100例:观察组术中采用碳纤维恒温加热垫保温(调节温度38-40 ℃),对照组采用普通棉被保温,监测两组术前、麻醉后10 min、麻醉后30 min、麻醉后60 min和术后2 h的体温及寒战情况。

结果与结论:①该加热垫具有防爆、电源净化、屏蔽隔离、输出保护、计算机控制、PWM调制等特点;③临床应用中,观察组未出现皮肤刺激与皮肤过敏反应;③手术过程中,观察组体温较为平稳,波动较小,术后     2 h与术前体温比较差异无明显差异(P > 0.05);对照组体温波动较为明显,呈明显下降趋势,术后2 h与术前体温比较差异显著(P < 0.05);观察组麻醉后10 min、麻醉后30 min、麻醉后60 min和术后2 h的体温高于对照组(P < 0.05);④对照组术后寒战发病率显著高于观察组(18%,5%,P < 0.05);⑤结果表明,该医用碳纤维恒温加热垫技术先进,使用安全、可靠,为临床中预防患者围手术寒战提供了一种新的方式。

Abstract:

BACKGROUND: It has been pointed out that perioperative hypothermia can increase the incidence of coagulation, acidosis, stroke, sepsis, pneumonia and myocardial infarction, so it is of great significance to monitor and maintain normal body temperature during perioperative period.

OBJECTIVE: To design a medical carbon fiber thermostatic heating pad to prevent perioperative hypothermia and reduce complications.

METHODS: The carbon fiber heating technology and medical equipment standard are combined and integrated into many advanced technologies. The system mainly consisted of power supply conversion, operation system, computer control system, PWM control and output, various heating pads and temperature controlling measurement system. A total of 200 patients undergoing epidural anesthesia in Zhengzhou First People’s Hospital were randomly divided into two groups: the observation group (n=100) was treated with the medical carbon fiber thermostatic heating pad (adjusting temperature 38-40 oC), and the control group (n=100) with common quilt. The body temperature and shivering were monitored before operation, 10, 30 and 60 minutes after anesthesia, and 2 hours after operation.

RESULTS AND CONCLUSION: (1) The heating pad had the characteristics of explosion proof, power purification, shielding isolation, output protection, computer control, and PWM modulation. (2) In clinical application, there was no skin irritation and skin allergy reaction in the observation group. (3) During operation, the body temperature of the observation group was relatively stable, and there was no significant difference in the body temperature in the observation group before and at 2 hours after operation (P > 0.05). However, the fluctuation of body temperature in control group was visible and showed a downward trend, and the body temperature in the control group showed a significant difference before and 2 hours after operation (P < 0.05). The body temperature of 10, 30, 60 minutes after anesthesia and 2 hours after operation was significantly higher in the observation group than the control group (P < 0.05). (4) The postoperative incidence of shivering in the control group was significantly higher than that in the observation group (18% vs. 5%, P < 0.05). To conclude, the medical carbon fiber thermostatic heating pad is advanced in technology, safe and reliable in use, providing a new way for the prevention of perioperative shivering.
