To determine whether sublingual temperatures are accurate in adult critical care patients with an oral endotracheal tube in place.
Repeated measures quasi-experimental.
University-affiliated tertiary care center in Western Canada.
Convenience sample of 33 adults (24 men, 9 women) with a mean age of 63 years undergoing scheduled open heart surgery and serving as their own controls.
Oral, rectal, and ambient temperatures were measured twice at a one-half hour interval the evening before surgery when subjects were not intubated and three times over an 8-hour period after surgery and after intubation. Pulmonary artery (core) temperature served as a reference and was measured along with endotracheal tube content temperature of the intubated subjects.
Descriptive and inferential statistics were used to analyze the data. Results of the study supported the accuracy of oral temperatures in critically ill patients who were intubated. Mean oral temperature measurements were neither statistically (p > 0.05) nor clinically (+/- 0.14 degrees C) significantly different from mean pulmonary artery temperature at any of the three measurement times after intubation and a mean difference of 0.01 degrees C (0.17 SD) was noted. This was not significantly affected by endotracheal tube content temperature (p > 0.05). Significantly high correlations between oral and pulmonary artery (r = 0.92 to 0.96) temperature measurements also were revealed. A significant difference (p = 0.0001) in rectal minus oral temperature discrepancy between subjects with and without an endotracheal tube was noted.
Sublingual and pulmonary artery temperature measurements of adult critical care patients who were orally intubated consistently showed close agreement during a thermally dynamic 8-hour period after open-heart surgery.
确定对于成年重症监护患者，在口腔留置气管内插管的情况下，舌下温度测量是否准确。
重复测量的准实验研究。
加拿大西部一所大学附属的三级护理中心。
便利样本，33名成年人（24名男性，9名女性），平均年龄63岁，接受择期心脏直视手术，且自身作为对照。
术前一晚受试者未插管时，每隔半小时测量口腔、直肠和环境温度两次；术后插管后8小时内测量三次。肺动脉（核心）温度作为参考，同时测量插管受试者的气管内导管内容物温度。
采用描述性和推断性统计方法分析数据。研究结果支持了对插管重症患者口腔温度测量的准确性。在插管后的三个测量时间点，平均口腔温度测量值与平均肺动脉温度在统计学上（p>0.05）和临床上（±0.14℃）均无显著差异，平均差值为0.01℃（标准差0.17）。这不受气管内导管内容物温度的显著影响（p>0.05）。口腔温度与肺动脉温度测量之间也显示出显著的高相关性（r = 0.92至0.96）。有气管内插管和无气管内插管的受试者之间，直肠温度减去口腔温度的差异有显著统计学意义（p = 0.0001）。
在心脏直视手术后的8小时热动态期间，成年口腔插管重症监护患者的舌下温度测量值与肺动脉温度测量值始终显示出高度一致性。
