Study type
Interventional
Description of intervention(s) / exposure
Patients included will be those consenting patients who are undergoing abdominoplasty, with the intervention/technique compared being the diathermy setting used during the operation. For excision of tissue and dissection of abdominoplasty flaps, a monopolar coagulation diathermy with power setting of 20W will be used for one group, whilst a monopolar coagulation diathermy with power setting of 35W will be used in the second group, and a monopolar cutting diathermy with power setting of 35W will be used for the third group
Diathermy will be used throughout the dissection portion of the abdominoplasty (excising out skin and raising abdominal flaps).
This is estimated to be the first 30 minutes of the operation.
The same 2 surgeons will operate with all three diathermy settings.
All other aspects of the abdominoplasty will proceed as per usual practice.
The control will be monopolar coagulation diathermy with power setting of 35W .
