Brief Summary
This prospective observational study aims to compare the effects of bilateral ultrasound-guided recto-intercostal plane block(RIPB) and bilateral ultrasound-guided external oblique intercostal plane block(EOIPB) on postoperative analgesia in patients undergoing elective laparoscopic cholecystectomy under general anesthesia. Both blocks are performed after anesthesia induction as part of routine preemptive multimodal analgesia practice. Patients who receive bilateral recto-intercostal plane block will be included in the RIPB group, and patients who receive bilateral external oblique intercostal plane block will be included in the EOIPB group. The primary outcome is cumulative intravenous tramadol consumption via patient-controlled analgesia during the first 24 postoperative hours. Secondary outcomes include postoperative pain scores at rest and during activity, rescue analgesic requirement, postoperative nausea and vomiting, time to mobilization, length of hospital stay, quality of recovery assessed using the Quality of Recovery-15 questionnaire, and block-related complications.

Study Arms (2)
RIPB Group
Patients who received bilateral ultrasound-guided recto-intercostal plane block after anesthesia induction as part of routine preemptive analgesia for elective laparoscopic cholecystectomy.
EOIPB Group
Patients who received bilateral ultrasound-guided external oblique intercostal plane block after anesthesia induction as part of routine preemptive analgesia for elective laparoscopic cholecystectomy.
Interventions
Bilateral external oblique intercostal plane block was performed under ultrasound guidance after anesthesia induction. Local anesthetic was injected into the fascial plane between the external oblique muscle and the intercostal muscles as part of routine preemptive analgesia.
Bilateral recto-intercostal plane block was performed under ultrasound guidance after anesthesia induction. Local anesthetic was injected into the fascial plane between the rectus abdominis muscle and the intercostal structures as part of routine preemptive analgesia.
