Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This is a randomised control trial with two arms, intervention and placebo. The intervention is instillation of a single dose of 2.5mg/kg of Ropivacaine into the pelvis at the completion of laparoscopic hysterectomy or three compartment endometriosis resection. The maximum dose administered to a patient will be 300mg and the fluid will be instilled into the pelvis via a laparoscopic port. The placebo arm will receive a matched volume per kg of normal saline into the pelvic. The intervention/placebo will be administered by the research team.
Intervention code [1] 318381 0
Treatment: Drugs
Comparator / control treatment
The control group will receive a normal saline placebo instilled into the pelvis at the completion of surgery. The weight based volume of 0.5% Ropivacaine will be used to determine the volume of study drug or placebo to be instilled according to the patients blinded study allocation.
Control group
Placebo

Efficacy
Statistical methods / analysis
96 patients required to show a 10% reduction in VAS score. Due to the inherent difficulties in diagnosing the extent of endometriosis pre surgery, we will recruit an additional 30% to account for loss to following and exclusions after commencing surgery.
