Abstract:
This study was concerned about comparing the degree and process of cardiopulmonary effect of propofol and midazolam. Forty-five adult patients,ASA grade Ⅱ, scheduled for elective operation, were randomly allocated to intravenously receiving midazolam 0.28mg?kg~(-1)(group Ⅰ,n=16), 0.40mg?kg~(-1) (group Ⅱ,n=16) ,or propofol 2.5mg?kg~(-1) (group Ⅲ,n=13) ,respectively. MAP ,HR, SpO_2 ,TV ,MV ,RR and P_(ET)CO_2 were monitored continuously before and in 30 minutes following the administration ,and the arterial blood gas analysises were performed before and 1,2,3,4,5,10,15,20 and 30 minutes after the administration. The results showed that in group Ⅰ, Ⅱ and Ⅲ after the administration separately,the maximal decrease of MAP were 20.0% ,22.8% and 22.20%, and occured in 10.8, 9.3 and 3.5 minutes;HR decreased maximally by 6.3% ,8.7% and 15.5%,TV by 76.6% ,81.3% and 91.3%/00 ,MV by 87.2%,91.6% and 93.6%,RR by 60.3%,67.5% and 83.6%; the incidences and durations of apnea were 37.5%vs 57.5 seconds,31.3%vs 68. O seconds and 76.9%vs 73.0 seconds. The MV recovered to the baseline 5 minutes in group Ⅲ and more than 10 minutes in group Ⅰ and Ⅱ following the administration. The arterial blood pH reduced and PaCO_2 increased significantly in three groups (P
