The Analgesic Effect of Transversus Abdominis Plane (TAP) Block Versus Wound Infiltration Versus Placebo Following Open Radical Prostatectomy, a Double Blinded, Randomized Clinical Trial
The Analgesic Effect of Transversus Abdominis Plane (TAP) Block Versus Wound Infiltration Versus Placebo Following Open Radical Prostatectomy, a Double Blinded, Randomized Clinical Trial
This study is conducted to evaluate different analgesic treatments effect following operation where the prostate gland is surgically removed.
The different treatments the investigators wish to investigate is:
Transversus Abdominis Plane (TAP) block.
The TAP block is a rather new method, where a local anaesthetic is deposited between the two inner abdominal muscles. Between these muscles, the nerves that innervates the anterior part of the abdominal wall is situated.
Wound infiltration
In this method you deposit a local anaesthetic in the edges of the wound.
Placebo
No active local treatment is given.
All patients who wish to participate will be allocated to one of three different treatment groups.
Group 1:
Will receive TAP block with a local anaesthetic and wound infiltration with saline.
Group 2:
Will receive wound infiltration with a local anaesthetic and TAP block with saline.
Group 3:
Will receive TAP block with saline and wound infiltration with saline.
Beside this local treatment all patients will be given systemic Paracetamol (tablet) and Ibuprofen (tablet).
In addition all patients will be given a pump containing morphine. The pump is connected to a button which the patient can activate when they experience pain. This enables the patient to control how much morphine he needs, following the operation.
The hypothesis is that the TAP block is superior in reducing pain and thereby reducing morphine consumption compared to wound infiltration and placebo.
