Efficacy of ultrasound-guided bilateral costal margin block in laparoscopy-assisted gastrectomy: A double-blind randomized trial
Authors' conclusion
As a novel and easily-performed technique, ultrasound-guided bilateral CMB can reduce opioid consumption in patients undergoing laparoscopy-assisted gastrectomy.
Study context
- Population
- Patients undergoing laparoscopy-assisted gastrectomy
- Participants
- 42 patients
- Comparison
- Block vs Control
- Blockn = 21
- Controln = 21reference
- Primary endpoint
- IV morphine equivalents
- Follow-up
- 24 h after surgery
Methodological detailsprospective, double-blind
- Prospective
- Double-blind
Primary result
As reported in the abstract
P < 0.001
Secondary outcomes
Titrated morphine consumption in post-anesthesia care unit (PACU) and intraoperative remifentanil consumption
- Lower in the block group than in the control group
Average pain scores in PACU and satisfaction with pain relief
- Relatively lower average PACU pain scores and more satisfaction with pain relief in the block group
Hospital LOS after surgery
- Comparable between the two groups (p > 0.05)
Safety
Adverse effects
- Comparable between the two groups (p > 0.05)
