Description of intervention(s) / exposure
Intervention: Intraoperative acupuncture during tonsillectomy procedure

Why: To assess if intraoperative acupuncture can affect postoperative pain score

How: With approval from the Hospital Ethics Committees, we plan to enroll 260 adults who are undergoing tonsillectomy into our study.
All prospective patients receive written informed consent prior to surgery. All patients are interviewed and consented by the anaesthetist the night before or on the day of surgery. They are all given a chance to ask questions at the interview and any further queries are to be addressed prior to the procedure.

All patients have their intravenous cannula inserted in the induction bay and also have 5 auricular acupuncture needles pads attached to each ear. In the acupuncture group, the Serin paper needle pads with a very small (0. 6mm) embedded needles are used. In the control group, the sham paper pads without needles were used instead. The needles in these sham paper pads were removed by the author prior to the operation day. In all patients, these needle pads are to remained in place for 5 days, and then removed by patients at home.

The patients are then brought into the operating room for induction of anaesthesia.

In the acupuncture group, immediately following induction of anaesthesia and prior to surgical stimulation, ten (10) body acupuncture needles are inserted prior to surgical stimulation. A standard surgical tonsillectomy with diathermy is then carried out. At the end of surgery, the body acupuncture needles are removed. The patients are then woken up and taken out to recovery.

In the control group, an identical procedure to that described above was followed, without the insertion of ten (10) acupuncture needles.




What:
For auricular acupuncture, paper pads with an embedded needle 0.2mm in diameter and 0.6mm in length were used (Serin Co, Shizuoka, Japan). In the control group, the needles were removed with a surgical needle holder by the author prior to the operation day to provide sham paper pads without needles.

For body acupuncture: Stainless steel acupuncture needles, 15 mm in length and 0.18 mm in diameter (Serin Co, Shizuoka, Japan), were used. The positions for the needles inserted, according to Chinese Medicine standards, are: LI4 bilaterally, LI20/Bitong bilaterally, CV(REN)22, GV(DU)20, LU1, PC6, ST44, SP6.

Who:All needle acupunctures were performed by Dr David Ho, an anaesthetist and a qualified acupuncturist with certification from the Australian College of Medical Acupuncturist (AMAC).
Where: all procedures were performed in operating rooms at Northwest Private Hospital
When/How much: All acupuncture is done only once.The body acupuncture needles were left in situ for the duration of surgery, and immediately removed at the completion of surgery prior to the patient being transferred to recovery room. The auricular acupuncture needles are left in-situ for 5 days postoperative and removed by patients at home.

Documentation/ Monitoring:
All patients enrolled are noted to have acupuncture (AC) intervention recorded on their anaesthetic record. A separate record for their in-hospital Pains Scores are included in their Medical Record which is filled out by nursing staff and doubled check against their own Pain Scores on hospital ward chart and Oxycodone does on the Medication chart. Another record is given for patients to record their Pain Scores and Oxycodone doses at home. Both of these are collected and collated by the research nurses when completed.

Immediately after the removal of acupuncture needles, all insertion sites are inspected for possible bleeding or erythema. These common complications are recorded on the acupuncture collection sheets, as well as any reported rare complications such as neurological impairment.

Comparator / control treatment
For auricular acupuncture, the process is exactly the same in the 2 groups in the awake patient. However, In the control group, the sham paper pads without needles were used instead of real paper pads with embedded needles for auricular acupuncture.

For body acupuncture, the only difference is that in the control group, patients do not receive body acupuncture. In the acupuncture group, ten body acupuncture needles are ionserted after the patients are sleep and removed prior to awakening.

Outcomes
Primary outcome [1] 322909 0
Pain score following tonsillectomy as assessed by the 0-10 Numerical Pain scale with the intervention of intraoperative acupuncture.
Timepoint [1] 322909 0

in the first 24 postoperative hours in hospital and on day 1,2 5 at home.
Secondary outcome [1] 380216 0
Oxycodone requirement following tonsillectomy as assessed by the number of doses given by nurses in hospital and by patients at home with the intervention of intraoperative acupuncture.
A separate record for their in-hospital Pains Scores are included in their Medical Record which is filled out by nursing staff and doubled check against their own Pain Scores on hospital ward chart and Oxycodone does on the Medication chart. Another record is given for patients to record their Pain Scores and Oxycodone doses at home. Both of these are collected and collated by the research nurses when completed.
Timepoint [1] 380216 0

in the first 24 postoperative hours in hospital and on postoperative days 1,2 and 5 at home
Secondary outcome [2] 391838 0
To qualitatively assess possible complications and safety of intraoperative acupuncture. Immediate complications such as erythema or bleeding is noted and recorded by staff in data collection sheets. Delayed reactions such as numbness or localised pain are queried by nursing staff and research nurses and recorded on data collection sheets.
Timepoint [2] 391838 0
in the first 24 postoperative hours in hospital and on day 1,2 5 at home.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
To minimise allocation bias, this randomisation programme was held by an independent collaborator. On the day of surgery, the anaesthetist would contact the independent collaborator with the names of the patients. The independent collaborator would then assign the patients to the respective groups and inform the anaesthetist just prior to the procedure as to which group the patients had been assigned.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The patients were randomised in blocks of 50 and assigned by a computer-generated programme to either the control or the acupuncture group. To minimise allocation bias, this randomisation programme was held by an independent collaborator.

Statistical methods / analysis
All our statistical analyses were performed by an independent statistician. Differences in demographic data were analysed using t-tests for continuous variables and chi-squared tests for categorical variables. Outcome data were analysed using simple linear regression for continuous variables and logistic regression for categorical variables. Data analysis was conducted using Stata v14.2 (StataCorp, College Station, TX, USA).
