Randomized Controlled Trial Clinical Trial
[Continuous total intravenous anesthesia is useful for postoperative pain management].
We compared postoperative pain in two groups. All anesthetic agents were continuously administered intravenously in a continuous PKF (propofol 2-10 mg.kg-1.h-1, ketamine 240 micrograms.kg-1.h-1 and fentanyl 0.4 microgram.kg-1.h-1) group. In a control group, anesthesia was maintained by GOI (N2O-oxygen-isoflurane). ⋯ To evaluate pain, VAS and Prince Henry Score on rest, cough and movement were taken 2 hrs and 5 hrs postoperatively, and in the morning and afternoon of the 1st as well as 2nd postoperative days. The continuous PKF group showed lower scores than the GOI group. It is a great advantage to use continuous PKF for postoperative pain management, and our data indicate that low dose ketamine may induce pre-emptive analgesia.
