简要总结
Laparoscopic cholecystectomy (LC) surgery causes postoperative severe pain. As part of multimodal analgesia aimed at reducing postoperative opioid consumption and providing effective analgesia, ultrasound (US)-guided transversus abdominis plane block (TAP) and external oblique intercostal plane block (EOIPB) will be applied as regional anesthesia methods. There is no study in the literature comparing OSTAP and EOIP blocks, and our goal is to evaluate the analgesic effectiveness between OSTAP and EOIP blocks in LC surgeries.
详细描述
Patients will be divided into two groups, and general anesthesia will be administered to all. Before extubation, one group will receive an external oblique intercostal nerve block, while the other group will receive an oblique subcostal transversus abdominis plane block. The randomization of the study will be carried out by a computer-generated randomization code (computer-generated) by a physician who will not be involved in patient follow-up. The interfascial plane block (either external oblique intercostal block or oblique subcostal block) will be provided to an anesthesiologist in a sealed envelope by an independent assistant staff member outside the study. The patient will not be aware of which block is applied. The anesthesiologist performing the block will not participate in the pain follow-up of the patients. Postoperative pain assessment and data collection will be conducted by another anesthesiologist unaware of the study.
For standardization, the block procedure will be performed by an experienced anesthesiologist who has completed at least 20 previous successful and uncomplicated procedures.
