Comparison of Two Pain-treatment Techniques After Cesarean Section

Overview

Comparison of two types of analgesia after cesarean section. All patients will anaesthetised with spinal technique. Ultrasound-guided transversus abdominis plane or quadratus lumborum block to treat postoperative pain. Postoperative pain will measured with visual-analogue scale (VAS). 1, 2, 6 months after surgery each patient will be called to assess neuropathic pain with Neuropathic Pain Symptom Inventory (NPSI).

Written consent will be obtained before the cesarean section. Only subarachnoidally anaesthetised patients may participate in the study. Pencil-point spinal needle and bupivacaine (Marcaine Heavy Spinal 0.5 %) will be used. At the end of surgery ultrasound-guided regional block will be performed. Each patient will be randomly allocated to one of the treated group: transversus abdominis plane block (TAP) or quadratus lumborum (QL). Patients receive 0.2 mL of local anesthetic solution (0.25 % bupivacaine) on each side. Postoperative pain will be measured with VAS (visual-analogue scale) 2, 4, 8, 12 and 24 hours after the end of operation. Paracetamol, metamizol, ketoprofen may be given as required. Whenever pain exceeds 40 (VAS) 5 mg of morphine will be given intravenously (maximum two dosages per day). 1, 3, 6 months patients will be called to assess neuropathic pain. Neuropathic Pain Symptom Inventory (NPSI) will be used.
