It is not unreasonable that the application of local anaesthesia to the intraperitoneal cavity should play a role in ERAS protocols. In order to reduce postoperative pain and reduce intra-abdominal to CNS signal transmission we will produce a transient "chemical affarenectomy". As part of the already established ERAS protocol at the Manukau Surgical Centre (MSC), my aim is to look at the effects of instillation of local anaesthesia to the intra-peritoneal cavity immediately after opening the abdominal cavity and we propose an ongoing LA infusion with an intraperitoneal catheter and external pump postoperatively.
