Conditions
Brief summary
The purpose of the study is to determine whether the use of heated, humidified carbon dioxide during laparoscopy lasting greater than 90 minutes results in less pain and shorter hospital stay than using cold, dry carbon dioxide (which is currently standardly used). Animal models show that use of cold, dry gas results in drying and damage to the cells in the lining of the abdomen, whereas using heated, humidified gas prevents this from occuring. Some human studies have shown that the heated, humidified gas results in less post-operative pain. Both the patients and the post-operative nursing staff will be blinded to the type of gas used. Patients will blinded to the type of gas used as randomisation occurs once they are under the anaesthetic. The type of gas used will not be recorded in the research notes and as such, the nursing staff will not be aware of the type of gas used.
Interventions
