21. EVALUATION THE ANALGESIC EFFECT AFTER CESAREAN SECTION BY BILATERAL QUADRATUS LUMBER BLOCK SINGER SHOT UNDER ULTRASOUND GUIDANCE WITH ROPIVACAINE PLUS DEXAMETHASONE
Main Article Content
Abstract
Object: Evaluate the analgesic effect after cesarean section by bilateral quadratus lumber block
single shot under ultrasound guidance with ropivacaine plus dexamethasone.
Methods: The study was conducted on 60 women who received spinal anesthesia for elective
cesarean section at Hanoi Obstetrics and Gynecology Hospital and received postoperative pain relief
with a single dose of bilateral quadratus lumber block under ultrasound guidance. Patients were
randomly divided into two groups: Group D received a mixture of 20ml ropivacaine 0.2% + 1ml
dexamethasone (2mg) on each side compared with group R using a mixture of 20ml ropivacaine
0.2% + 1ml 0.9% NaCl on each side.
Results: The study results showed that a single dose of Ropivain - Dexamethasone pain relief
better than using Ropivacaine alone: VAS pain scores at rest and during exercise at 48 hours after
surgery of group D were lower than group R and all less than 4 points; pain relief time of group D
lasted longer than group R statistically significant (1083.8 minutes vs. 610.67 minutes; p<0.05); The
amount of morphine consumed in the first 24 hours of group D was statistically significantly lower
than that of group R (4.47 vs 7.4 mg, p<0.05).
Conclusion: Single dose bilateral quadratus lumber block under ultrasound guidance with
Ropivacain- dexamethasone mixture has better analgesic than Ropivacaine alone.
