Effects of right lateral position on endoscopic ultrasonography for upper digestive tract / 中国实用护理杂志

ABSTRACT

Objective To investigate which is better for gastroduodenal endoscopic ultrasound (EUS) between right lateral position and left lateral position of patients guided by nurses. Methods A total of 79 patients were randomly assigned to the left and right lateral position groups. Each patient received EUS examination in three parts, which were sinuses ventriculi, duodenal bulb and descendant duodenum. The operating time and the water volume of each patient were recorded in the procedure of EUS. Results Operating time in sinuses ventriculi, duodenal bulb and descendant duodenum of left lateral position group was (9.0±4.0) min, (6.5±3.2) min and (13.6±10.9) min, while (5.7±3.0) min, (3.6± 1.7) min and ( 6.6±5.7) min in right lateral position group, the differences were significant (t=3.098, 2.190, 3.210, P<0.05) . In the meantime, water volume was (892.0±169.5) ml, (898.6±145.9) ml and (1 012.0± 333.2) ml in sinuses ventriculi, duodenal bulb and descendant duodenum of left lateral position group, while (327.1±79.3) ml, (260.6±30.4) ml and (263.8±17.7) ml in three parts of right lateral position group, respectively. Significant differences were found in water volume among subgroups (t=13.798, 11.290, 4.930, P<0.01 or 0.05). Conclusions In the process of EUS for submucosal lesions at gastric antrum and duodenum, right lateral position instructed by nurses can shorten the operating time and make the procedure easier. This might reduce risks of regurgitation, aspiration, and other related complications.
