Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The patients are recruited during the consenting process for laparoscopic appendicectomy.

The randomisation and blinding is achieved by the computer software from the Armadale Pharmacy that randomly assigns a blinded solution in the form of 50ml sterile syringes (can have maximum 3 syringes per patient) labelled as number 1-128. These blinded solutions will contain 64 as placebo saline and the other 64 as 0.2% Ropivicaine. The pharmacy will blind the labeling hence blinding both the surgeon and anaesthetist.

Efficacy
Statistical methods / analysis
Sample size determined by power study approximately 100. For a 50% difference between the post-operative analgesic consumption in the control and treatment group would be of interest. Assuming a one sided significance of 0.05 and a power of 0.8, a total of 51 patients per group with a total sample size of 102 for a one tailed test and for two tailed test then the recommendation is 128 patients in total.

Summary
Brief summary
This study investigates the analgesic effect of intraperitoneal injection of a long acting local anaesthetic agent (Ropivacaine) during laparoscopic (keyhole) appendicectomy.

Trial participants will be randomly divided into two groups. One group will receive intraperitoneal Ropivacaine during laparoscopic appendicectomy while the other will receive normal saline.

The consumption quantity of total Fentanyl analgesia, the presence of shoulder tip pain and post surgery nausea or vomiting will be recorded up to 16 hours post surgery.

The study aims to determine whether the use of Ropivacaine during laparoscopic appendectomy is an useful analgesic adjunct.

The primary aim of this study will be to determine whether using Ropivacaine will reduce total amount of analgesia used, hence reducing post-operative pain, and its effect on the incidence of post laparoscopic appendicectomy shoulder tip pain and nausea or vomiting.
