Determination of Gastric Volume by Different Administration Methods before Painless Gastroscopic Anesthesia and Risk assessment of aspiration

Abstract

Objective: To observe the volume of gastric contents in the dacronin group versus streptaprotease particles and dacronin group in order to better predict the risk of reflux aspiration under anesthesia.Methods: A total of 90 patients underwent gastroscopy under general anesthesia in Shenzhen Hospital (Fu Tian) of Guangzhou University of Chinese Medicine from July 2021 to July 2022, Of 42 men, Of the 48 women, Age, from 18-65 years old, ASAⅠ－II，The cross-sectional area of the gastric antrum in group (group A) and streptomase particles and dacronin group (Group B) (antral cross-sectional area, CSA), gastric volume (gastric volume, GV), GV / W (gastric volume / body weight) statistics were analyzed by T-test.  

Results: GV of group A was 28.59 ± 20.74 and GV of group B was 38.79 ± 18.89, T test showed P=0.0168, statistically significant comparison between the two groups. GV / W in Group A was 0.48 ± 0.36, and GV / W in Group B was 0.65 ± 0.40; according to two-sample T-test, P=0.0355 showed differences in the same groups, the supine (supine) and semi-supine, supine and right and right supine (P <0.001).  

Conclusion: Oral administration of 60ml fluid is safe 30 minutes before gastroscopy, and antral ultrasound in the right lateral position can most easily achieve positive results.
