Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
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 Quincke spinal needle (B. Braun Melsungen AG, Melsungen, Germany). Both the intervention group and the sham group received spinal anaesthesia.
Intervention code [1] 283891 0
Prevention
Comparator / control treatment
In control group, needles were inserted at 4 points that are remote from any classically described meridian or extraordinary acupoint and (2) no current was applied to the needles. These 4 points were located as follows: 3 cm lateral to the ST36 and ST37 respectively bilaterally.
Control group
Placebo

Outcomes
Primary outcome [1] 286143 0
Shivering was graded using a scale similar to that validated by Tsai and Chu*: 0 = no shivering, 1 = piloerection or peripheral vasoconstriction but no visible shivering, 2 = muscular activity in only one muscle group, 3 = muscular activity in more than one muscle group but not generalized, and 4 = shivering involving the whole body.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
A total number of 85 patients scheduled for elective ureteroendoscopy(URS) surgical procedures of either sex under spinal anaesthesia between June 2010 and May 2011 were prospectively included in the study.
All participants were randomly assigned to group A (electroacupuncture) or group P (placebo) on the basis of a concealed allocation approach (according to the computer random number table allocation group) using opaque sealed envelopes containing the randomization schedule. These envelopes were opened immediately before electroacupuncture. There were no restrictions on randomization. Two separated groups were invited to the study. The sealed envelopes were accessible only to the first group of acupuncturists who were to perform electroacupuncture. The second group of anesthetists who were to perform spinal anesthesia and patients were blinded to the electroacupuncture allocation. Another nursing staff unware of the electroacupuncture study were responsible for collection the necessary data.
