Conditions
Keywords
MTAPA, OSTAP, Postoperative pain, TAP Block, VAS Score
Brief summary
This randomized controlled trial aims to compare the postoperative analgesic efficacy of M-TAPA block and OSTAP block in patients undergoing laparoscopic inguinal hernia repair. Pain scores, analgesic consumption, and patient satisfaction will be evaluated.
Detailed description
Prospective, randomized, single-blind, controlled study including 90 patients undergoing elective laparoscopic inguinal hernia repair. Patients will be randomized into three groups: M-TAPA, OSTAP, and control. Postoperative pain scores (VAS), analgesic consumption, time to first analgesic requirement, and patient satisfaction will be assessed over 24 hours.
Interventions
Ultrasound-guided bilateral M-TAPA block performed with 20 mL of 0.25% bupivacaine per side
PROCEDUREOblique Subcostal Transversus Abdominis Plane Block (OSTAP)
Ultrasound-guided bilateral OSTAP block performed with 20 mL of 0.25% bupivacaine per side
OTHERStandard Analgesia use (paracetamol, contramal)
Patients received standard postoperative analgesia without regional block

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Total analgesic consumption in 24 hours | 24 hours postoperative | Total amount of dexketoprofen consumed in the first 24 hours after surgery |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Postoperative Pain Intensity (VAS Score) | 0 (15 minutes), 2, 4, 8, 12, 16, and 24 hours postoperative | Postoperative pain intensity assessed using the Visual Analog Scale (VAS, 0-10), where 0 indicates no pain and 10 indicates worst imaginable pain. |
| Time to First Analgesic Requirement | Within 24 hours postoperative | Time from the end of surgery to the first request for analgesic medication |
| Tramadol Consumption | 24 hours postoperative | Total amount of tramadol administered within the first 24 hours after surgery. |
| Patient Satisfaction Score | 24 hours postoperative | Patient satisfaction assessed using a Likert scale evaluating overall satisfaction with postoperative pain management |
| Incidence of Postoperative Nausea and Vomiting | 24 hours postoperative | Incidence of nausea and vomiting observed during the first 24 hours after surgery. |
