[Clinical observation of remifentanyl and propofol injection in total intravenous anesthesia for percutaneous radiofrequency ablation].

OBJECTIVE
To explore the efficacy and safety of remifentanyl and propofol injection in total intravenous anesthesia for percutaneous radiofrequency ablation.


METHODS
60 patients scheduled for PRFA were divided randomly into two groups:group A and group B. Each group contained 30 patients. Those in group A received remifentanyl and propofol injection, and the patients in group B were given oxycodone hydrochloride. The mean arterial pressure (MAP), heart rate (HR) and pulse oxygen saturation (SPO2) were measured and recorded by monitor during the operation. The chest muscle rigidity, respiratory depression, nausea and vomitting, hypotensio and VAS were also recorded.


RESULTS
Compared with the preoperative,MAP, HR in group A decreased significantly during the operation, increased in group B (P < 0.05). VAS was significantly lower in group A than that in group B (P < 0.05). 2 patients had respiratory depression, 1 patient had nausea and vomiting reaction in group A.2 patients had vagus reflex, 3 patient had nausea and vomitting reaction in group B.


CONCLUSION
Total intravenous anesthesia with remifentanyl and propofol for PRFA is safe and reliable. Respiratory and circulation should be monitored instantly and strictly.
