Objective: To observe the gastric emptying time (GET) of and the therapeutic effect of Weihuigui Decoction (WHGD) upon functional dyspepsia (FD).
Methods: GET of 64 FD patients and 20 healthy volunteers was measured by real time ultrasonography. The measurements were performed at fasting, 0, 10, 20, 30, 40 and 50 min after drinking water, the area of gastric antrum, internal diameter of the section of anterior posterior walls in corpus ventriculi fundus junction region, intitating time of gastric contraction and contractive times in 2 min were recorded. Twenty patients selected randomly were treated with WHGD 100 ml, three times a day, for 2 weeks consecutively, to observe the improvement of clinical effect and gastric emptying.
Results: GET was delayed in 66% of 64 FD patients as compared with that of control, and it was related with gastric contraction initiating time and contraction times in 2 min. WHGD could improve the clinical symptoms and GET of FD patients.
Conclusion: WHGD has obvious therapeutic effect in treating FD.
