NCT06238830

Brief Summary

The study will include 80 patients undergoing Laparoscopic Cholecystectomy Surgery as part of elective requirements. The study is a single-center, prospective, randomized controlled trial The aim of the study is

  1. 1.To investigate the effectiveness of multimodal analgesia, which includes the newly introduced external oblique intercostal plane block, with the assistance of NOL (Nociception Level), in the management of postoperative pain following commonly performed Laparoscopic Cholecystectomy surgeries.
  2. 2.This approach is intended to objectively assess changes in postoperative recovery scores

Outcome Measures

Primary Outcomes (1)

  • Change From Baseline in Multimodal Analgesia on the Nociceptive Level İndex(NOL)

    The NOL index is a single number between 0 and 100. A NOL between 0 and 25 represents a physiologically suppressed response adequately inhibiting harmful stimuli, indicating sufficient analgesia. A NOL index greater than 25 (continuous or fluctuating) for multiple minutes signifies the patient is perceiving pain. Higher values indicate a stronger nociceptive response. An index consistently below 10 for more than a minute may suggest excessive anti-nociception, prompting consideration for reducing analgesics. If regional analgesia is employed, lower NOL values are anticipated. The dosage of remifentanil will be increased if the patient's NOL value remains elevated for 2 minutes when it surpasses 25.The number of changes in Ultiva dosage, NOL values will be recorded before intubation, after intubation, during thoracic entry, and during inflation and deflation, as well as at the time of extubation.

Study Arms (2)

GROUP M

In patients undergoing elective Laparoscopic Cholecystectomy Surgery, after routine anesthesia induction, a magnesium loading dose of 30 mg/kg will be administered intravenously. Subsequently, a magnesium infusion will be initiated at a rate of 10 mg/kg/hour. Afterward, in the supine position, necessary field preparation and ultrasound (USG) setup will be conducted to administer the External Oblique Intercostal Plane (EOIP) block.The procedure will be applied unilaterally. After desufflation, patients will receive 50 mg dexketoprofen as standard analgesia administered intravenously as a non-steroidal anti-inflammatory drug (NSAID).

GROUP K

As part of standard analgesia, 50 mg dexketoprofen, administered intravenously as a non-steroidal anti-inflammatory drug (NSAID), will be applied, and these patients will be considered as the control group. All patients will undergo general anesthesia induction with 1 µg/kg fentanyl, 2-3 mg/kg propofol, and 0.6 mg/kg rocuronium bromide. During anesthesia maintenance, a mixture of 50% O2 and air will be administered, and sevoflurane will be used at a minimum alveolar concentration of 0.8 (with a target MAC value of 0.8-1.2). Additionally, remifentanil will be administered at a rate of 0.01-0.2 mcg/kg/min. The remifentanil dose range will be increased if the patient\'s Nociceptive Level (NOL) value remains elevated for 2 minutes when it exceeds 25. BIS monitoring will be performed for all patients, and the BIS value will be maintained between 40-50.
