Midazolam, a water soluble benzodiazepine, was compared with diazepam as the changes of eardiopulmonary function during sedation under the spinal anesthesia in elderly patients. The results were as follows; 1) Cardiovascular effect. At the conclusion after diazepam 0.05 mg/kg(Group D) or midazolam 0.02 mg/kg(Group M) injection, systolic, diastolic pressure and heart rate were significantly decreased(P$lt;0.05) in the both group from 3 min to 30 min, but maintained within normal range. However, it is not significant difference that each group. 2) Respiratory effect. SaO decreased significantly at 3 min. in M-group after midazolam injection but there was not significant difference from change in D-group. Respiratory rate, pH and PaCO₂ were not significantly changed between D-group and M-group. However, PaO₂ was significantly decreased(p$lt;0.05) within normal range at 3 min. in M-group after midazolam IV and significant difference between both groups. From the above results, We have concluded that IV administrationf small dose of diazepam or midaaolam during spinal anesthesia had a little changed in cardiopulmonary function. However, sedative effect was efficient.
