Effect of dexamethasone combined with ropivacaine on the transverse abdominal muscle plane block
To explore the effect of transverse abdominis plane (TAP) block with dexamethasone combined with ropivacaine.
Methods
2
A total of 80 adult patients with ASA grade Ⅰ‑Ⅱ elective laparoscopic surgery under general anesthesia combined with TAP block were randomly divided into 2 groups. The experimental group (Group A
n
=40) received 0.375% ropivacaine 20 mL and 5 mg dexamethasone 1 mL per side
and the control group (Group B
n
=40) received 0.375% ropivacaine 20 mL and 0.9% saline 1 mL per side. The main observation indexs were analgesic duration
VAS score
incidence of nausea and vomiting
and patient satisfaction.
Results
2
Compared with those in group B
analgesic maintenance time was significantly prolonged (
P
<
0.05)
postoperative VAS scores were lower (
P
<
0.05)
and patient satisfaction rate was higher in group A (
P
<
0.05). The incidence of nausea and vomiting was similar between the two groups
and the difference was not statistically significant.
Conclusion
2
Dexamethasone combined with ropivacaine during TAP block can significantly prolong analgesia time
reduce postoperative pain
improve analgesia quality and increase patient satisfaction.
