Brief summary
Background: The aim of the present study was to verify the effect of electroacupuncture in the prevention of shivering caused by regional anaesthesia. Methods: In this prospective, randomized, single-blind study, 80 ASA I and II patients undergoing urological surgery were included. Spinal anaesthesia was performed in all patients with bupivacaine 15 mg. The patients were randomly allocated to receive placebo acupuncture (Group P, n = 40) or electroacupuncture (group A, n = 40) for 30 min before spinal anaesthesia. Shivering score was recorded at 5 min intervals. Heart rate, arterial pressure and tympanic temperatures were recorded using standard non-invasive monitors before intrathecal injection and thereafter at 5, 10, 15, 20, 25 and 30 min. Results: After 15 min, the number of patients with observed shivering above 3 was 13 in group P and 3 in group A. The number of patients with a shivering score above 3 was statistically significantly higher in group P compared with the other group. Conclusion: The prophylactic use of electroacupuncture was effective in preventing shivering developed during regional anaesthesia.
Interventions
1.In active acupuncture group, trained and accredited acupuncturist performed acupuncture on ST36 and ST37 bilaterally in a depth not over 0.5 cun before anaesthesia. Then an electro-stimulator NihonRiko TOKKI MOEL III (NihonRiko Medical Co., Ltd., Nagasaki, Japan) was connected to the needles with a current of 1 mA and a frequency of 3 Hz for 30 minutes.
2. Subarachnoid anaesthesia was instituted at either L3/4 or L4/5 interspaces. Hyperbaric bupivacaine, 5 mg/ml, 15 mg was injected using a 25G
