Clinical Trial
Midazolam for continuous sedation in Japanese critical care patients: phase II study.
This prospective study was undertaken to evaluate the efficacy and safety of midazolam as a sedative agent in 14 critically ill patients without coma admitted to the intensive care unit at Nihon University Itabashi Hospital, Japan. Adequate sedation (sedation score [SS] 4-6) was induced with 0.058- 0.372 mg/ kg midazolam and maintained with a dose range of 0.03-0.4 mg/kg per h. Most burn or trauma patients required higher midazolam doses than patients with cardiovascular disease. ⋯ Pharmacokinetic analysis of the population suggested that lower drug clearance rates correlated with presence of complications. Plasma concentrations (EC50) of SS 5, estimated by logistic regression analysis, varied among patients (mean 194 ng/ml). Midazolam infusion achieved successful sedation in this critical care setting, but the optimum dose differed by patient and was influenced by the presence of complications.

Clinical Trial
Midazolam for continuous sedation in Japanese patients in the critical care setting: phase II study.
This prospective, phase II study was carried out to evaluate the efficacy and safety of midazolam as a sedative agent in nine critically ill Japanese patients without coma who had been admitted to an intensive care unit. An adequate level of sedation (sedative score [SS] 4-6) was induced by midazolam 0.14 - 0.39 mg/kg and maintained with a dose range of 0.08 - 0.24 mg/kg per h. One patient was excluded from the efficacy analysis since optimum sedation was not maintained by continuous infusion. ⋯ The 50% of effective concentration values of SS 5, estimated by logistic regression analysis, varied greatly (mean, 251 ng/ml). In conclusion, midazolam infusion achieved successful sedation in this critical care setting. The optimum dose differed among the patients, however, and was influenced by the presence of complications.
