Description of intervention(s) / exposure
The PC6 acupoint is the meridian point in the pericardium channel and located on the inner forearm between the extensor carpi radialis and palmaris longus tendons one sixth of the distance from PC7 on the medial wrist crease to PC 3 in the cubital fossa (WHO, 2008). Participants in the intervention group (acupressure wristband) will have the Seaband (Registered Trademark) wristbands applied to both wrists ensuring the bead stimulates the Neiguan (PC 6) after establishment of IV access and invasive monitoring in the operating theatre. The wristbands will be covered with opaque bandaging to ensure blinding. The wristbands will be removed at 36 hours from admission time to ICU after final outcome measurement.

Comparator / control treatment
Participants in the placebo (sham) wristband group will have a sham (without bead) Seaband (Registered Trademark) wristbands applied to both wrists at the position of the Neiguan (PC6) acupoint after establishment of IV access and invasive monitoring in the operating theatre. The wristbands will be covered with opaque bandaging to ensure blinding. The wristbands will be removed at 36 hours from admission time to ICU after final outcome measurement.

Patients in the acupressure group will experience less nausea and vomiting postoperatively compared with patients in the sham group. This will be assessed 6 hours from arrival to the ICU, at 8 hours post arrival, 4 hourly up to 24 hours and then at 36 hours on a bedside Case Report Form. Nausea will be assessed on a 10 point scale (“0 = no nausea” to “10 = severe nausea”). For vomiting, all episodes of retching or vomiting in the 36 hour time period will be recorded on the bedside Case Report Form.

Statistical methods / analysis
Data analysis will be conducted using Stata/SPSS. The Intention To Treat (ITT) principle will be used for all analyses. Descriptive statistics will be reported using appropriate measures of spread and locations to answer the feasibility questions. Differences between study groups of incidence of nausea and vomiting, measured regularly over the first 36 hours, will be analysed using repeated measures logistic regression with either generalized linear models (GenLin) or generalized estimating equations (GEE). Potential confounders (mixed effects) will be identified and differences adjusted for within the models. Nausea severity will use repeated measures general linear models (GLM), whilst other nontemporal outcomes (e.g., usage of rescue therapy and quality of recovery) will use multivariate logistic regression and linear regression models. Due to the sample size (N = 80 - 100), statistical significance is not expected to be found, yet general trends will provide preliminary data to provide support for a large scale RCT. For all statistical comparisons, a significance level of p=0.05 will be employed.). The aim is to establish protocol fidelity and data will be recorded at each assessment of nausea regarding whether wristbands are correctly positioned; and data will be collected in relation to patients lost to follow up and missing data. The feasibility of placing the wristbands on patients after establishment of IV access and invasive monitoring in the operating theatre will be established through interviews with staff.
As sample size of 40 per group (n = 80 in total) has been determined. As this is a feasibility study the sample size was based on Hertzog's (Considerations in Determining
Sample Size for Pilot Studies, Research in Nursing & Health, 2008, 31, 180–191) estimations for efficacy studies that argues that a sample size of 40 per group will provide appropriate power for a pilot study.

Summary
Brief summary
Post-operative nausea and vomiting (PONV) are unwanted complications following anaesthesia and surgery. The occurrence of PONV ranges from 20% to 80%, despite optimal pharmacologic interventions. The burden of caring for patients post cardiac surgery in healthcare system world-wide is immense. In 2009-2010, In Australia alone, over 230,000 cardiac procedures were performed, and the number and rate of cardiac procedures are increasing. Similar to many countries world-wide, cardiovascular disease (CVD) remains the most expensive disease group in Australia, costing about $5.9 billion in 2004–05 with just over half of this money spent on patients admitted to hospital. As part of their illness treatment and recovery, cardiac surgery patients experience varying rates of PONV; studies across various populations have reported rates ranging from 22% to 50%.
