    Abstract:
    BACKGROUD: Postoperative nausea and vomiting (PONV) is one of the most common complications after total thyroidectomy under general anesthesia. Total intravenous anesthesia (TIVA) has been documented to prevent PONV in patients undergoing total thyroidectomy. Penehyclidine, an anticholinergic agent with an elimination half-life of over 10 h, is widely used as premedication to reduce glandular secretion. This study aimed to explore the preventative effects of penehyclidine with propofol-remifentanil-TIVA to single-TIVA on PONV in patients undergoing total thyroidectomy. METHODS: A total of 100 patients scheduled for total thyroidectomy were randomly assigned to either the penehyclidine group (n = 50) or TIVA group (n = 50). Propofol and remifentanil were was used for TIVA in all patients. No patients who received premedication. Patients were administrated with either 5 ml of normal saline or 0.5 mg of penehyclidine soon after anesthesia induction. The incidence of nausea and vomiting, the severity of nausea, the requirement of rescue antiemetics, and adverse effects were investigated during the first 24 h in two time periods (0-2 h and 2-24 h). RESULTS: The overall PONV incidence during the 24 h after surgery was significantly lower in the penehyclidine group compared with the TIVA group (12% vs 36%, P < 0.005). Besides, the incidence of nausea and the incidence of vomiting were significantly lower in the penehyclidine group compared with the TIVA group at 2-24 h after surgery. However, there was no significant difference between the two groups at 0-2 h after surgery. CONCLUSIONS: Administration of penehyclidine under TIVA with propofol-remifentanil is more effective for prevention of PONV than TIVA alone, especially 2-24 h after total thyroidectomy.
