Summary

The goal of this single-center, prospective, double-blind randomized controlled clinical trial is to explore preventive interventions for chronic postoperative pain (CPSP) in patients undergoing minimally invasive cardiac surgery. The main questions it aims to answer is: the incidence of CPSP is high and severe, and there is no safe and effective method for prevention and treatment. The participants in the dexamethasone palmitate (DXP) group will receive a single paravertebral space infusion of 21 ml of the first dose of analgesia, consisting of 0.5 percentage ropivacaine 20 ml and dexamethasone palmitate 1ml. The participants in dexamethasone sodium phosphate (DXM) group will receive a single infusion of a paravertebral space first dose of 21 ml of analgesic containing 0.5 percentage ropivacaine 20 ml and dexamethasone sodium phosphate 1ml. Then both groups use a continuous paravertebral nerve block pump for postoperative analgesia. The liquid of the pump is 250 ml 0.2 percentage ropivacaine. The background of the pump is set to 5 ml/h and PCA is set to 5 ml at an interval of 30 min.

Interventions

DRUG

Dexamethasone Palmitate

a single paraverteal space infusion of 21 ml of the first dose of analgesia, consisting of 0.5 percentage ropivacaine 20 ml and dexamethasone palmitate 1ml. Then, a continuous paraverteal nerve block pump was connected for postoperative analgesia. The liquid of the pump was 250 ml 0.2 percentage ropivacaine. The background of the pump was set to 5 ml/h and PCA was set to 5 ml at an interval of 30 min.

DRUG

Dexamethasone Sodium Phosphate
