Brief summary

BRIEF SUMMARY: Laparoscopy and hysteroscopy is a common day case gynaecological procedure. This operation involves keyhole surgery, inserting a small telescope-like device or fibreoptic lens into the abdomen via a 10mm port. This enables direct visualisation of inside the abdomen. There is also one other cut on the abdomen of 5mm, where a thin metal probe is inserted. Finally, a second fibreoptic device, is inserted inside the womb via the vagina and cervix, and the inside of the womb is visualised. A scraping of the womb tissue is taken and sent to the pathology laboratory to be analysed under a microscope. Patients usually go home the same day, unless there have been complications. Pain relief for this procedure has not been studied in any recent large trials. Current pain management involves use of pain relief tablets after the operation, and intravenous analgesics during the operation, including ropivacaine, depending on the anaesthetist. We aim to evaluate the use of intraperitoneal Ropivacaine. This is a local anaesthetic medication that can be squirted inside the abdomen at the areas that have been manipulated including the womb and fallopian tubes and injected at port sites, which are the two small incisions on the abdomen. HYPOTHESIS: We hypothesise that the use of ropivacaine at the end of the procedure will reduce post operative pain and hasten recovery after a diagnostic laparoscopy and hysteroscopy.

Interventions

The intervention is using the local anaesthetic, ropivacaine, intraperitoneally, at the end of the diagnostic hysteroscopy and laparoscopy. The dose used is 20mls of 0.25% (100mg) of ropivacaine. It will take less than two minutes to administer. The intervention treatment will only be administered once.
