Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Ropivacaine
Treatment: Drugs - 0.9% Saline

Experimental: LA - Use of Ropivacaine

Placebo comparator: Placebo - Use of 0.9% saline


Treatment: Drugs: Ropivacaine
In the treatment arm patients will receive 10mls 0.75% ropivacaine diluted to 50mls with saline immediately before closure.

At closure, two small 2 mm catheters will be placed in the peritoneal cavity at the site of the operation to infuse local anaesthesia. This will penetrate through the skin once closure is complete. This will be attached to a small infusion pump (On-Q pain buster). This pump will contain 270mls of 0.2% ropivacaine. After 68 hours the pump will be stopped and the catheter will be removed in a similar fashion as routine drain removal.

Treatment: Drugs: 0.9% Saline
In the placebo arm patients will receive 50 ml 0.9% saline into the peritoneum soon after the creation of the laparotomy.

At closure, two 2 mm catheters will be placed in the peritoneal cavity at the site of the operation to infuse local anaesthesia. This will penetrate through the skin once closure is complete. This will be attached to a small infusion pump on-Q pain buster). This pump will contain 0.9% saline. After 68 hours the pump will be stopped and the catheter will be removed in a similar fashion as routine drain removal.
