Performing Nasogastric Tube (NGT) insertion is very challenging in anesthetized and intubated patients. The current study aimed at comparing Digital (two-finger) and Video Laryngoscopy methods for NGT insertion in the mentioned patients.
The present single-blind clinical trial was performed on 76 intubated patients, who were randomly divided into two groups. Groups A and B underwent Video Laryngoscopy and Digital (two-finger) methods, respectively. Then, the success rate, the number of attempts to insert NGT, duration of insertion, hemodynamic parameters, and patients' satisfaction level were recorded and compared between groups.
The mean duration of NGT insertion in group A was significantly higher than that of group B (19.07 ± 2.07 vs 11.53 ± 2.16 seconds; P value=0.001). The success rate was higher in group B (94.7% vs. 78.9%; P value=0.042). Considering the interfering factors such as patients' body mass index (BMI), the odds of success in group B was reported to be 8.49 times higher than that of group A (P value =0.028).
Digital method can be considered as a safe and appropriate method of NGT insertion for intubated cases with high success rate and speed of performance.
在麻醉和插管患者中进行鼻胃管（NGT）插入极具挑战性。本研究旨在比较数字（双指）法和视频喉镜法在上述患者中插入NGT的效果。
本单盲临床试验对76例插管患者进行，这些患者被随机分为两组。A组和B组分别采用视频喉镜法和数字（双指）法。然后，记录并比较两组之间的成功率、插入NGT的尝试次数、插入持续时间、血流动力学参数以及患者满意度。
A组NGT插入的平均持续时间显著高于B组（19.07±2.07秒对11.53±2.16秒；P值=0.001）。B组的成功率更高（94.7%对78.9%；P值=0.042）。考虑到患者体重指数（BMI）等干扰因素，B组成功的几率据报道比A组高8.49倍（P值=0.028）。
数字法可被视为一种安全且合适的NGT插入方法，对于插管病例成功率高且操作速度快。
