Abstract

Background: Control and maintenance of endotracheal tube cuff pressure and prevention of sore throat are major concerns in post-anesthesia care. Aim: This study aimed to evaluate changes in the pressure of the endotracheal tube cuff filled with saline versus air and post-anesthesia sore throat when the position is altered from supine to lateral. Method: Thisdouble-blind randomized clinical trial was performed on 60 participants under lateral hip replacement surgery in an educational, research, and treatment center in the northeast of Iran in 2018-2019. After intubation, the cuffs of the intervention and control groups were filled with saline and air, respectively. Cuff pressures and Visual Analog Scale of sore throat were measured and analyzed using repeated measures ANOVA and Pearson's correlation coefficient in SPSS software, version 20. Results: The mean ages of the participants in the intervention and control groups were 45.8±11.6 and 40±13.1 years, respectively. Changes in the cuff pressure of different time points were statistically significant in both intervention (P=0.03) and control (P=0.02) groups. Based on the results of the independent sample t-test, the pain score was significantly different between the intervention (0.1±0.4) and control (1.1±2.1) groups 12 h post-surgery (P=0.01). The results of the Pearson’s correlation coefficient revealed a significant association between the pain score 12 h post-surgery and pressure difference of the fifth and first stages in the control group (r=0.585, P=0.001). In addition, the 12-h pain score and the pressure difference of the fifth and fourth stages were also significantly correlated in the control group )r=0.479, P=0.01). Implications for Practice: Based on the findings, in the lateral-position hip surgery, the use of saline to fill the endotracheal tube cuff could lead to better control of cuff pressure and may also reduce the postoperative sore throat.

体位对充气气管导管袖口压力与生理盐水压力的影响:一项双盲随机临床试验

背景:控制和维持气管插管袖口压力和预防咽喉痛是麻醉后护理的主要关注点。目的:本研究旨在评估当体位由仰卧位变为侧卧位时，充满生理盐水的气管内管袖口与空气的压力和麻醉后喉咙痛的变化。方法:本双盲随机临床试验于2018-2019年在伊朗东北部的一个教育、研究和治疗中心对60名接受侧位髋关节置换术的参与者进行了研究。插管后，干预组和对照组的袖口分别充满生理盐水和空气。在SPSS软件20版中，采用重复测量方差分析和Pearson相关系数对袖带压力和喉咙痛视觉模拟量表进行测量和分析。结果:干预组和对照组的平均年龄分别为45.8±11.6岁和40±13.1岁。干预组(P=0.03)和对照组(P=0.02)不同时间点袖带压力变化均有统计学意义。独立样本t检验结果显示，术后12 h干预组(0.1±0.4)与对照组(1.1±2.1)疼痛评分差异有统计学意义(P=0.01)。Pearson相关系数分析结果显示，对照组患者术后12 h疼痛评分与第5期、第1期压差有显著相关性(r=0.585, P=0.001)。对照组12 h疼痛评分与第5、4期压差也有显著相关性(r=0.479, P=0.01)。实践意义:根据研究结果，在侧位髋关节手术中，使用生理盐水填充气管内管袖口可以更好地控制袖口压力，也可以减少术后喉咙痛。

期刊介绍： The Evidence Based Care Journal (EBCJ) is an international, peer reviewed, scientific journal that seeks to promote the development and exchange of knowledge that is directly relevant to all spheres of patient care. The primary aim is to promote a high standard of clinically related scholarship which advances and supports patient care in practice. The Journal also aims to promote the international exchange of ideas and experience that draws from the different cultures in which practice takes place. Further, EBCJ seeks to enrich insight into clinical needs and the implications for patient care intervention and models of service delivery. Emphasis is placed on clinical practicality of research findings and strength of study design. EBCJ is essential reading for anyone involved in healthcare professions, whether clinicians, researchers, educators, managers, policy makers, or students. Contributions are welcomed from other health professionals on issues that have a direct impact on patient care.
