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.Conclusion 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.
