Objective To discuss the postoperative analgesic effects of transverses abdominis plane(TAP) block with dexamethasone and ropivacaine on patients undergoing hysterectomy. Methods Eighty-four patients undergoing hysterectomy were randomly divided into three groups. Group A(n=29) and B(n=27) received ultrasound-guided TAP block by bilateral injection of total40 ml of 0.375% ropivacaine and 10 mg dexamethasone and 40 ml of 0.375% ropivacaine, respectively. Group C(control group, n=28) did not receive TAP block. The three groups received postoperative PCIA treatment. Recording was made in the VAS scores and Ramsay scores 3, 6, 12, 18, 24, and 48 h after the operation, the sufentanil consumption during the operation, and PCIA pressing times and adverse reactions within 48 h after the operation. Results The VAS scores of group A and B were significantly lower than those of group C 3, 6, and 12 h after the operation(P 0.01). The VAS scores of group A were significantly lower than those of group B and C 18, 24, and 48 h after the operation(P 0.01). There was no significant difference among the Ramsay scores of the three groups at each time points after the operation. The perioperative consumption of sufentanil in group C was larger than that in group A and B(P 0.01). Within 48 hours, the PCIA pressing times of group A were the least, and those of group C were the most. The adverse reactions in group C were the least. Conclusion As to the patients undergoing hysterectomy, TAP block with dexamethasone and ropivacaine can prolong the analgesic duration and reduce the consumption of opioid drugs with less adverse reactions.
