拔牙用麻药常含血管收缩剂,它可延长麻醉时间和止血。本实验通过血糖浓度测定以观察其对全身代谢的影响。材料和方法实验组是需拔除双侧下颌第三磨牙患者10名,对照组为10名健康者。麻醉药是2％利多卡因加1:80000肾上腺素液和3％丙胺卡因加0.03IU/ml苯赖加压素液两种。实验组每个患者分两次在4周内拔除两侧下颁第三磨牙和查血糖,对照组也分两次在4周内 Tooth extraction often contain vasoconstriction agents, it can extend the anesthesia time and stop bleeding. The experiment by blood glucose concentration to observe the impact on the body's metabolism. Materials and methods The experimental group is to remove the bilateral mandibular third molar patients 10, the control group of 10 healthy persons. The anesthetics are 2% lidocaine plus 1: 80000 adrenaline and 3% prilocaine plus 0.03IU / ml phenylephrine. The experimental group, each patient twice in four weeks to remove both sides issued the third molars and check blood sugar, the control group also divided into two in 4 weeks
