Scientific title
Study hypothesis	Does the use of local anaesthetic nerve blocks to numb the operation site, once the patient is anaesthetised, reduce port operative pain in patients undergoing appendectomy? This will be compared to infiltration of the skin alone with local anaesthetic.
Ethics approval(s)	Not provided at time of registration
Condition	Signs and Symptoms: Pain
Intervention	1. Group A: local infiltration of skin prior to incision with bupivacaine according to weight. 2. Group B: half the bupivacaine by weight infiltrated into the skin prior to incision. As incision deepened second half of bupivacaine given under direct vision deep to external oblique, lateral to the incision, to create field block.
Intervention type	Other
Primary outcome measure	1. Post operative pain in recovery: by questionnaire in recovery 2. Post operative pain on ward at 4 and 8 hours post op: by questionnaire 3. Post operative pain at 24 hours or at discharge, whichever is sooner. 4. Hours from operation to discharge.

Participant inclusion criteria	All open appendectomies undertaken for acute appendicitis at Royal Berkshire Hospital. At time of analysis different sub groups formed according to operative findings: gangrenous / perforated appendix or normal appendix.
Participant exclusion criteria	1. Laparoscopic appendectomies. 2. Appendix removed at time of planned laparotomy (i.e. not through small incision). These exclusion criteria exist as we wish to judge the effect of local anaesthetic on post operative pain. Where a different size wound is left (laparoscopic or laparotomy) it would be an unfair comparison. Where the initial operation is appendectomy via a lanz incision but an alternative pathology is found or the wound is extended for a laparotomy then the patient will be included in the study until the time of analysis.
