151例老年病人硬膜外麻醉血压变化分析

STUDY ON CHANGE OF BLOOD PRESSURE FOR 151 SENILE PATIENTS WITH PERIDURAL ANESTHESIA

本文分析１５１例老年病人硬膜外麻醉对血压的影响，表明：①麻醉后血压和脉搏均有显著下降（Ｐ＜０．０１）；②麻醉药首剂在１５ｍＬ以上较１４ｍＬ以下麻醉后血压下降更为显著（Ｐ＜０．０１）；③腹部手术比下肢手术麻醉后血压下降更显著（Ｐ＜０．０１）。作者指出，老年病人施行硬膜外麻醉应选择最低有效剂量，同时严密观察其对麻醉和手术的反应，对血压、脉搏、呼吸、ＳＰＯ２、心电图进行连续监测，以确保安全。

The paper studied effect of peridural anesthesia on blcod pressure. Results:(1)Blood pressure and pulse ratcehad a significant decrease(P<0.01);(2)The first dosage of narcot-ic beyond 15 ml had more significant effect of decreasing blcod pressure than dosage below 14 ml(P<0.01):(3)Patient with abdominal operation had more significant decrease of blood pressurethan patient with lower extremity operation ( P<0.01).The author suggested that the adminis-tration of narcotic should be at a minimum effective dosage for senile patient undergoing periduralanesthesia and a careful observation on patient’s reaction,blood pressure,pulse,respiration,SPO2and EKG is essential.
