Abstract:

Objective To observe the effect of abdominal compression operation in preventing hypoxemia in painless gastroscopy anesthesia. Method 188 patients who underwent painless gastroscopy examination in the outpatient and inpatient departments of Yanbian University Affi liated Hospital from September 2021 to November 2022 were randomly divided into an observation group and a control group, with 94 patients in each group, using a random number table method. The control group was treated with nasal cannula oxygen inhalation, while the observation group was assisted with abdominal compressions on the basis of the control group. The lowest pulse oxyhemoglobin saturation (SpO2) level, incidence of hypoxemia, gastroscopy examination time, incidence of withdrawal and suspension of examination, total amount of propofol used, awakening time, and incidence of postoperative adverse reactions were compared between the two groups of patients. Result The lowest SpO2 level of the observation group patients was higher than that of the control group, and the gastroscopy examination time was shorter than that of the control group. The incidence of dropout and hypoxemia were both lower than those of the control group, and the diff erences were signifi cant (P ＜ 0.05). However, there was no signifi cant diff erence in heart rate and incidence of adverse reactions between the two groups of patients when they reached the lowest SpO2 level (P ＞ 0.05). Conclusion Abdominal compression operation can eff ectively prevent the occurrence of hypoxemia in painless gastroscopy, maintain a high SPO2 level, shorten the time of gastroscopy, and improve the effi ciency of gastroscopy.
