Pain-relieving Methods After Laparoscopic Hemicolectomy

Pain-relieving Methods After Laparoscopic Hemicolectomy, Effects of Transabdominal Plain Block and Quadratus Lumborum Block

Effects of Transabdominal Plain Block and Quadratus Lumborum Block After Laparoscopic Hemicolectomy. The pain relief, bowel function and discharge.

This study is proposed to explore the effects of transabdominal plane block and quadratus lumborum block after laparoscopic hemicolectomy.

After laparoscopic hemicolectomy there is a need for good analgesia. When the analgesia is adequate the patients mobilisation, bowel function and discharge is faster. Earlier, epidural block has been used for the analgesia but now the hemicolectomy is laparoscopic procedure and there is no need for central block anymore. Still patients needs opioids after the operation. Because of the opioids side effects, there is a need to find better analgesia methods.

In this study investigators compare peripheral nerve blocks, transabdominal plane and quadratus lumborum, for analgesia after laparoscopic hemicolectomy. Also investigators are comparing these analgesia methods and traditional orally analgesics. Patients receive transabdominal or quadratus lumborum block after induction using ropivacaine 5 mg/ml 20 ml per side. The third group is a control group witch analgesia is taken care with traditional orally analgesics.

After surgery investigators follow postoperative pain, opiate consumption, bowel function, nausea and mobilisation.

Investigators coal is to find if the transabdominal plain block or quadratus lumborum block prefer traditional analgesia methods after laparoscopic hemicolectomy.
