Summary

The goal of this study is to learn about the effectiveness of TAP block for pain relief after vascular surgery on the abdominal aorta. The main question the investigators are looking to answer is whether the TAP block lowers the dose of opioid required after abdominal aortic surgery.

Detailed description

The surgery on the abdominal aorta requires extended haemodynamic monitoring and is performed under general anaesthesia. After applying general anaesthesia, the patients will receive a TAP block (subcostal approach) before the start of the surgery. During the procedure the patients will receive both opioid and nonopioid analgesics, as part of the standard perioperative protocol for abdominal aortic surgery. After the procedure all patients will receive following the standard protocol for pain relief after abdominal aortic surgery - NSAIDs and nonopioid analgesics regularly. All patients will postoperatively receive opioid as a rescue drug as needed (PCA). Participants will be randomly allocated in two groups, where one group will receive local anaesthetic for the TAP block and the control group will receive normal saline for the TAP block. The anaesthetist, the nurses and doctors in the postoperative care will all be blinded as to the group in which each patient is allocated. The participants will be followed from surgery until discharge from hospital.
