Randomized Controlled Trial Comparative Study Clinical TrialIntra-operative epidural morphine, fentanyl, and droperidol for control of pain after spinal surgery. A prospective, randomized, placebo-controlled, and double-blind trial.
The present study was conducted to investigate the analgesic effects of intra-operatively administered epidural morphine in patients undergoing surgery for lumbar disc disease. Three treatment groups were constituted: one with 5.0 mg morphine and 2.5 mg dehydrobenzperidol (DHB) in 10 ml physiological saline, one with 5.0 mg morphine and 0.1 mg fentanyl in the same amount of saline, and one placebo group with saline only. The test solution was injected epidurally via catheter after haemostasis and before closure of the wound. ⋯ It was shown that additional epidural fentanyl offers no significant improvement of postoperative analgesia. No significant reduction of adverse effects could be found in the morphine/droperidol group compared to the morphine/fentanyl group. In conclusion, the intra-operative epidural application of morphine is a safe, effective and simple method for achieving sufficient analgesia in the first 24 hours after lumbar spinal surgery for disc disease.

Randomized Controlled Trial Comparative Study Clinical TrialKetamine for analgosedative therapy in intensive care treatment of head-injured patients.
Ketamine was supposed to be contra-indicated in head injured patients although it possesses numerous advantages over other commonly used analgosedative drugs. Referring to these potential advantages and the lack of definitive data about its effect upon ICP, CPP or neurological development, we conducted a prospective study in which moderate or severely head injured patients (n = 35) were prospectively allocated to receive treatment either with a combination of ketamine or midazolam or fentanyl and midazolam. The initial dose was 6.5 mg/kg/day midazolam, 65 mg/kg/day ketamine or 65 micrograms/kg/day fentanyl and was later adjusted due to clinical requirements for a period of 3 to 14 days. ⋯ A comparison of the remaining patients revealed a lower requirement of catecholamines (significant on first day, p<0.05), an on average 8 mm Hg higher cerebral perfusion pressure and a 2 mm Hg higher intracranial pressure in the study [corrected] group. Enteral food intake was better in the study group. The outcome was comparable in both groups with or without inclusion of withdrawn patients.
