Brief summary

It is aimed that patients who will undergo laparoscopic gallbladder surgery will experience less pain after surgery and require less morphine-derived painkillers. In relation to this, it is expected to reduce the risk of side effects such as nausea, vomiting, shoulder pain, shortness of breath after surgery. To achieve this, we aim to determine the most effective and long-lasting pain relief method. For this reason, a total of 128 patients between the ages of 18-70 who will undergo gallbladder surgery were planned to be included in the study, including one group of patients with transabdominis plane block (TAPB), one group of patients with Quadratus lumborum plane block (QLB) and one group of patients with intravenous painkillers (IVA). In addition to postoperative agitation assessment and visual pain assessment at 30 minutes, 2, 4, 12 and 24 hours, possible side effects such as nausea, vomiting, shoulder pain, respiratory distress, pulse and blood pressure drop will be observed and recorded. In addition, the total amount of morphine-derived painkillers consumed in the first 24 hours after surgery and the duration of hospital stay will be observed and recorded.

Interventions

1-Group QLB (quadratus lumborum plane block): 20 ml of 0.25% bupivacaine will be used each time for plane block on both sides 2- Group TAPB (transverse abdominis plane block): 20 ml of 0.25% bupivacaine will be used each time for plane block on both sides - Medical records will be audited to monitor adherence to the intervention. -each patient will be administered 0.25% bupivacaine for each side (a total of 40 ml of 0.25% bupivacaine will be used) - plane blocks will be applied under ultrasoun

After the block application, the patient was taken to the operating room and standard general anaesthesia was applied. Patients will be monitored for pain and side effects at 30th minute, 2nd hour, 4th hour, 12th hour and 24th hour in the postoperative period. - Both plane blocks are applied for analgesia in the postoperative period and aim to reduce opioid consumption in the postoperative period.
