Post-operative Pain
Conditions
Keywords
Post-operative pain, Wound bleeding requiring exploration, PTH, RLN complication, Hypocalcaemia complication
Brief summary
Primary: To compare the post-operative pain in patients with neck extension and without neck extension. Secondary: To determine the benefit of neck exposure and peri-operative complications, which include duration of operation, intra-operative blood loss, recurrent nerve (RLN) injury and hypocalcaemia in both groups. Hypothesis: Patients who undergoing thyroidectomy without neck extension will have less post-operative pain and there are no significant difference of post-operation complications between both groups.
Detailed description
Conventional open thyroid surgery is still one of the most common operations performed globally. Traditionally, patients who undergoing thyroid surgeries are usually positioned with extended neck by using pillow under shoulder in order to facilitate neck exposure and make the surgery easier. However, the degree of benefit from the extended neck is doubtful and there is little objective evidence that suggest extended neck thyroid surgery offers better outcomes. On the the hand, over-extension of the neck should be avoided because of it is associated with post-operative pain, vomiting, spinal damage and stroke. The objective of the present study is to compare the post-operative pain in patients with neck extension and without neck extension. In addition to that, we also like to determine the benefit of neck exposure and peri-operative complications, which include duration of operation, intra-operative blood loss, recurrent nerve (RLN) injury and hypocalcaemia in both groups. This is a prospective randomized controlled trial, which will be conducted from 1st of March 2012 till 30th September 2012. Given that approximately 300 to 400 patients would undergo thyroid surgery in each year, we estimated 180 patients will be recruited and randomly divided into 2 groups (neck extension and no neck extension) before undergoing open thyroid surgery for this trial. Visual analogue scale (VAS) is used to determine the post-operative pain. Primary end point and other peri-operative variables are then analyzed with SPSS software.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Post-operative pain score | First postoperative week | Post-operative pain ranges from 0 to 10 according to the Visual Analogue pain scale (VAS), and which 0 is 'No pain' and 10 is 'Worst possible pain' |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Surgically related complications | Immediate and after 6 months | Neck exposure, duration of operation, skin incision length, intra-operative blood loss, RLN injury, post-operative hypocalcaemia |
| Postoperative pain scores | Day 0, day 1 and after two weeks | Post-operative pain ranges from 0 to 10 according to the Visual Analogue pain scale (VAS), and which 0 is 'No pain' and 10 is 'Worst possible pain' |
