We evaluated the effects of ropivacaine for pain relief after robotic thyroid surgery (RoT).
PATIENTS AND METHODS:
Patients (n = 108) scheduled for RoT were randomized into ropivacaine (n = 54) or control (n = 54) groups. After surgery, 40mL of 0.25% ropivacaine or 0.9% saline (control) was instilled into the skin flap. Postoperative pain intensity (visual analog scale; VAS), analgesic requirements (fentanyl), and adverse events were assessed at 1, 2, 4, 8, 16, and 24 hours postoperatively.
103 patients completed the study protocol. VAS scores were lower in the ropivacaine group than control group (P = 0.010); however, VAS scores were not significantly different after 8 hours postoperatively. Total analgesic consumption was higher in controls than ropivacaine-treated patients (P = 0.01). Adverse events did not differ between the two groups.
Ropivacaine instillation after RoT reduces acute postoperative pain and analgesic requirements without adverse events.
