• Conditions: Post Operative Pain

• Registration Number: NCT06483581
• Lead Sponsor: Cumhuriyet University

Brief Summary

The goal of this study is to compare the analgesic efficacy of M-TAPA block and TAP block in patients undergoing laparoscopic appendectomy surgeries

Detailed Description

There will be two randomized groups: Group M-TAPA (n=15), Group TAP (n=15). All patients will have standard general anesthesia. Group M-TAPA patients will receive bilateral M-TAPA block with 0.25% bupivacaine (total volume of 40 ml). Group TAP patients will have bilateral lateral-TAP block with 0.25% bupivacaine (total volume of 40 ml). All blocks will be performed after general anesthesia induction, before skin incision. All patients in the study will receive 50 mg dexketoprofen and 1 gr paracetamol intravenos (i.v.) 10 minutes prior to skin closure. All patients will have ibuprofen 3x400 mg in postoperative 24 hours (maximum dose 1200 mg/day). Numerical rating scale (NRS) will be used to assess postoperative pain on 1st, 6th, 12th, 18th and 24th hour after the surgery. 50 mg tramadol will be administered as a rescue analgesic in all patients.Total tramadol consumption will be calculated.

Arm && Interventions

Group	Intervention	Description
TAP	TAP block with bupivacaine 25%	Patients will have bilateral lateral-TAP block with 0.25% bupivacaine (total volume of 40 ml) before the surgery for postoperative pain control.
M-TAPA	M-TAPA block with bupivacaine 25%	Patients will have bilateral M-TAPA block with 0.25% bupivacaine (total volume of 40 ml) before the surgery for postoperative pain control.

Primary Outcome Measures

Name	Time	Method
Comparing the numerical rating scale scores	Postoperative 24 hours	Numerical rating scale will be used for pain assessment. The scores of the numerical rating scale changes between 0 to 10 points. 10 points mean "the most severe pain that the patient ever had". 0 point means "there is no pain." Higher scores mean worse outcome.

Secondary Outcome Measures

Name	Time	Method
Comparing total tramadol consumption	Postoperative 24 hours	Postoperative analgesic need
