About this study
Official title: Midpoint Transverse Process to Pleura Block vs Erector Spinae Plane Block for Postoperative Analgesia in Laparoscopic Sleeve Gastrectomy
The aim of this study will be to compare between MTP and ESPB in terms of postoperative pain score in patients undergoing laparoscopic sleeve gastrectomy
- Conditions
- Bariatric Sleeve Gastrectomy
- Being tested
- Erector Spinae Plane Block (ESPB) group, Midpoint Transverse Process to Pleura Block (MTPPB)
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Erector Spinae Plane Block (ESPB) groupProcedure or surgery
will receive ESPB volume of 20 mls bupivacaine 0.25 % at level T7 bilaterally
Midpoint Transverse Process to Pleura Block (MTPPB)Procedure or surgery
will receive MTPB volume of 20 mls bupivacaine 0.25 % at level T7 bilaterally
| Study group | Role | What they receive |
|---|---|---|
| Group A (ESPB): Bilateral ESP | Active comparator | block at T7 with 20 mL of 0.25% bupivacaine on each side Receives: Procedure: Erector Spinae Plane Block (ESPB) group |
| Group B (MTPB): Bilateral MTP | Active comparator | block at T7 with 20 mL of 0.25% bupivacaine on each side Receives: Procedure: Midpoint Transverse Process to Pleura Block (MTPPB) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Mean postoperative pain numeric rating scale
Abdominal pain will be assessed using numeric rating scale which includes 10 degrees of which zero is no pain and 10 is maximum pain ever
Measured: pain will be evaluated first in postanesthesia care unit then at 1, 3, 6, 8, 12, 18, 24 hours posoperative

Questions about this trial
What is this clinical trial studying?
A study testing Erector Spinae Plane Block (ESPB) group and Midpoint Transverse Process to Pleura Block (MTPPB) in people with Bariatric Sleeve Gastrectomy, run by Ain Shams University at 1 site in Egypt.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
