Effect of Preemptive Ibuprofen and Dexketoprofen in Patients Undergoing Laparoscopic Cholecystectomy

The primary aim of this study is to investigate the effects of preventive ibuprofen and dexketoprofen on postoperative opioid requirement in patients undergoing elective laparoscopic cholecystectomy. The secondary aim is to compare routine administration of preemptive ibuprofen and dexketoprofen in terms of intraoperative hemodynamic parameters, postoperative complications, and patient satisfaction

Study Protocol, Methodology, Procedure: The study will be conducted with 90 patients aged 18-65 years with an ASA score of I and II who are planned for elective laparoscopic cholecystectomy. Patients converted to open surgery during laparoscopy and those with an ASA score of III and IV will be excluded from the study. All the patients will undergo physical examination and laboratory tests 1 day prior to the procedure. On the same day, each patient will be informed about VAS scoring system which is based on a 0-10 scale representing the severity of pain and the patients will be asked to grade their postoperative pain on this scale, where 0 indicates no pain and 10 indicates the most severe pain.

Placebo Group will receive 100 cc of isotonic solution within 30 min before the procedure. Dexketoprofen Group will receive 50 mg iv dexketoprofen in addition to 100 cc of isotonic solution within 30 min before the procedure. Ibuprofen Group will receive 800 mg iv ibuprofen in 100 cc of isotonic solution within 30 min before the procedure. Hemodynamic parameters including heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), and oxygen saturation (SpO2) will be recorded every 10 min for each patient both preoperatively and throughout the procedure. Additionally, total operative time will be recorded for each patient. The surgical procedure will be performed under general anesthesia. Anesthetic induction will be achieved with iv 2 mg/kg propofol, 2 mcg/kg fentanyl, and 0.6 mg/kg rocuronium. Anesthetic maintenance will be achieved with 8% desflurane, 40% O2, and 1 mcg/kg fentanyl. After the surgery, deep and subcutaneous infiltration of trocar insertion sites will be achieved with 4 cc of 0.5% bupivacaine. Moreover, to antagonize the effects of muscle relaxants, intravenous 0.015 mg/kg atropine and 0.04 mg/kg neostigmine will be administered. Patient-controlled analgesia (PCA) will be adjusted to a bolus dose 25 µg of fentanyl with a maximum of 6 doses/h, lockout interval of 10 min, and no basal infusion.

Postoperative Analgesia: Intravenous PCA will be adjusted to a bolus dose 25 µg of fentanyl with a maximum of 6 doses/h, lockout interval of 10 min, and no basal infusion.

Throughout laparoscopy, an intraabdominal pressure of 12-14 mmHg will be maintained. After the procedure, the patients will be transferred to the recovery room. In the recovery room, patients with a modified Aldrete score of 9 or more will be transferred to the general ward. VAS scores at postoperative 1, 2, 4, 6, 12, and 24 h will be recorded as resting VAS scores. The nurses/physicians recording the VAS scores will be blinded to the analgesic drugs and the patient groups. Patients with a VAS score of ≥4 will receive additional 50 mg tramadol in 100 cc of isotonic solution. Total procedure time will be recorded for each patient. Postoperative events occurring within the first 24 h including nausea, vomiting, mouth dryness, itching, palpitation, and headache will be recorded for each patient. At the end of the procedure, a survey will be performed to assess patient satisfaction regarding postoperative pain and other complications. To achieve this, the patients will be asked to grade their satisfaction on a 1 to 3 scale, in which 1 represents poor, 2 represents fair, and 3 represents good outcome.
