Abstract:
Objective To investigate the utility of anesthesia depth monitoring of BIS during general anesthesia without tracheal intubation.Methods Sixty patients underwent surgery with local anesthesia were randomly divided into three groups of Ⅰ ,Ⅱand Ⅲ,who were sedated with propofol by TCI propofol 1.0,1.5,2.0μg/ml,respectively.HR,MAP,SpO2 BIS and MOAA/S score were recorded at l0min before operation(T0) .during local anesthesia ( T1) , at 30min after incision (T2) , at 60min after incision (T3) , and the end of operation (T4).Results BIS values declined with the decrease of MOAA/S.MOAA/S score was lower in group Ⅲ than that in group Ⅰ (all P < 0.05).Respiratory depression was seen in 3 cases in group Ⅲ.The difference of MAP had statistical significance between level 3 and level 2 of MOAA/S in group Ⅱ and group Ⅲ (P < 0.05).Conclusion Propofol 1.0 ～ 1.5 μg/ml given by TCI could produce optimal depth of sedation with less side effects in surgery during local anesthesia.
