Postoperative analgesic effectiveness of ultrasound‐guided bilateral erector spinae plane block vs. rectus sheath block for midline abdominal surgery in a low‐ and middle‐income country: a randomised controlled trial
Authors' conclusion
Erector spinae plane blocks are more effective than rectus sheath blocks for the management of postoperative pain following midline abdominal surgery.
Study context
- Population
- Patients aged 18–65 y undergoing midline abdominal surgery in a LMIC72 analysed
- Participants
- 72 patients
- Comparison
- Ultrasound-guided bilateral ESP block vs rectus sheath block
- ESPn = 36
- Rectus sheathn = 36reference
- Primary endpoint
- Total postoperative analgesia consumption, postoperative pain severity and time to first rescue analgesic
Methodological detailsprospective, parallel, blinded patients, care providers and outcome assessors
- Prospective
- Parallel
- Blinded patients, care providers and outcome assessors
Primary result
As reported in the abstract
Postoperative opioid consumption
P = 0.003
Secondary outcomes
