[Effect of preconditioning of thermopaste application at Shenque (CV 8) on stretch reflex induced by procedure for prolapse and hemorrhoids in patients with hemorrhoids].

OBJECTIVE

To observe clinical effect, feasibility and security of preconditioning of thermopaste application at Shenque (CV 8) for relieving stretch reflex induced by procedure for prolapse and hemorrhoids (PPH).

METHODS

A total of 100 cases of mixed hemorrhoids (stage III and IV) patients were randomized into 1.0 h, 0.5 h, 0 h and control (no application) groups (n = 25 in each group) according to a random number table. Thermopaste was applied to Shenque (CV 8) 1.0 h and 0.5 h before PPH or conducted simultaneously with PPH. The mean arterial pressure, heart rate, blood oxygen saturation of patients before and after anastomose operation, and the incidence of adverse reactions within 24 hours after the procedure were monitored and recorded. The patient's pain degree was assessed by using visual analogue scale.

RESULTS

After the preconditioning, of the 25 patients in the 0.5 h group (0.5 h G), 14 experienced marked improvement (in the stretch reflex during PPH), 10 had an improvement, and 1 was invalid, respectively. The markedly effective rate and the total effective rate were 56% and 96%, respectively. The therapeutic effects for inhibiting stretch reflect being from the better to the poorer were 0.5 h G > 1.0 h G > 0 h G >NG. The heart rate and blood pressure from more stable to lesser stable were 0.5 h G> 1.0 h G > 0 h G > NG. The patients' pain reaction during operation and their adverse effects of nausea, vomiting, abdominal distention and abdominal pain, etc. occurred during operation also presented the same tendency in the 4 groups.

CONCLUSIONS

Thermopaste application to Shenque (CV 8) can effectively prevent and control visceral reflex in patients undergoing PPH, which effect is significantly better when conducted 0.5 hour before the operation.
