Abstract

Objective: Comparison of effects on hemodynamics, respiratory, and some side effects of 0.2% Ropivacaine combined with 4 mg Dexamethasone in ultrasound-guided quaratus lumborum block for post-cesarean analgesic managemnet.

Methods: A randomized controlled clinical trial conducted on 60 parturients undergoing spinal anesthesia for cesarean section, with postoperative pain management using ultrasound-guided quadratus lumborum block with 20 ml Ropivacain 0.2% (R group) versus a mixture of 20 ml Ropivacaine 0.2% and 4 mg Dexamethasone (RD group).

Results: The hemodynamics and respiration of the parturient after bilateral quadratus lumborum block were stable. The rate of postoperative nausea and vomiting in the RD group was significantly lower than in the R group (10% vs. 30%, p < 0.05). The rate of itching in the RD group was 6.67% and in the R group was 10% (p > 0.05). There were no cases of complications: infection, urinary retention, anesthetic poisoning…

Conclusion: Bilateral quadratus lumborum block for postoperative analgesia following cesarean section using 0.2% Ropivacaine combined with 4 mg Dexamethasone represents a safe analgesic technique: maternal hemodynamic and respiratory parameters remained stable following the block; postoperative nausea and vomiting incidence was significantly reduced, with no documented complications such as infection, urinary retention, or other adverse events.
