This study aimed to compare the body temperature, normothermia, and extubation times of patients heated with forced air warming method based on whether they underwent on-pump or off-pump coronary artery bypass graft.
This quasi-experimental study comprised 109 patients who underwent coronary artery bypass graft operation in the cardiovascular surgery department of a university hospital and a private hospital in Afyonkarahisar. Patients were divided into the following two groups: group 1 comprised 65 patients who underwent on-pump coronary artery bypass graft and group 2 comprised 44 patients who underwent off-pump coronary artery bypass graft. All patients included in the study were heated with forced air warming method. Preoperative and postoperative data were collected using the Patient Identification Form and the Patient Tracking Form, consisting of 16 items in total. Data were analyzed using the Statistical Package for the Social Sciences 18.0 software.
Even though the preoperative body temperature, postoperative first body temperature, second hour body temperature, and extubation time did not exhibit a significant difference depending on the operating method, a significant difference was observed regarding the first, third, fourth, and fifth hour body temperatures and time to reach normothermia based on the operating method (p<0.05). Notably, the off-pump group's body temperatures in the first, third, fourth, and fifth hours were higher compared with the on-pump group. Furthermore, the off-pump group reached normothermia (145.22±72.54 minutes) earlier or faster compared with the on-pump group (206.84±89.30 minutes). The body temperatures, extubation times, and normothermia were not observed to exhibit significant differences based on the gender (p>0.05). A statistically significant relation was not observed between the patient's body temperature and their age (p>0.05). However, a low but positive and significant (p<0.05) correlation was observed between the extubation times (r=0.197) and age, as well as time to reach normothermia (r=0.237) and age.
This study concluded that forced air warming method is an effective technique to minimize the time to regain normothermia among patients who underwent the on- and off-pump coronary artery bypass graft.
本研究旨在比较接受体外循环或非体外循环冠状动脉搭桥术的患者采用强制空气加温法时的体温、正常体温及拔管时间。
这项准实验研究纳入了在阿菲永卡拉希萨尔的一所大学医院和一家私立医院心血管外科接受冠状动脉搭桥手术的109例患者。患者被分为以下两组：第1组包括65例行体外循环冠状动脉搭桥术的患者，第2组包括44例行非体外循环冠状动脉搭桥术的患者。纳入研究的所有患者均采用强制空气加温法。术前和术后数据通过患者识别表和患者追踪表收集，这两份表格共包含16项内容。数据采用社会科学统计软件包18.0进行分析。
尽管术前体温、术后首次体温、术后第二小时体温及拔管时间根据手术方式未显示出显著差异，但基于手术方式，在术后第一、第三、第四和第五小时体温及达到正常体温的时间方面观察到显著差异（p<0.05）。值得注意的是，非体外循环组在第一、第三、第四和第五小时的体温高于体外循环组。此外，与体外循环组（206.84±89.30分钟）相比，非体外循环组达到正常体温的时间更早或更快（145.22±72.54分钟）。基于性别，体温、拔管时间及正常体温未显示出显著差异（p>0.05）。患者体温与年龄之间未观察到统计学上的显著关系（p>0.05）。然而，拔管时间（r=0.197）与年龄以及达到正常体温的时间（r=0.237）与年龄之间观察到低但呈正且显著的相关性（p<0.05）。
本研究得出结论，强制空气加温法是一种有效的技术，可缩短接受体外循环和非体外循环冠状动脉搭桥术患者恢复正常体温的时间。
