Laryngeal mask airway general anesthesia combined epidural block in laparoscopic cholecystectomy

Abstract

Objective To observe the feasibility of laryngeal mask ventilation general anesthesia com- bined epidural block in laparoseopie eholecystectomy. Methods One hundred and forty eases of selective laparoscopie eholecystectomy were performed to T8～T9 gap catheterization, with 1.5 percent lidoeaine epi- dural block, block levels in the following T4. After conventional anesthesia into 4# or 5# LMA, balloon gas was injected in 20 mL～30 mL, manual ventilation, respiratory resistance and the situation thorax ups and downs were observed. Results The patients epidural catheterization smoothly, in the anesthesia plane fol- lowing T4, insert the LMA blood pressure, heart rate without significant change. Pneumoperitoneum after the rebound in blood pressure[(20.6 5.0) mm Hg], heart rate did not change significantly, and then airway pressure increased[(5.7 1.6)cm H2O] , surgery performed smoothly, and quickly regained consciousness after the surgery, when all patients admitted gallbladder, they have resumed breathing independently. Con- dusion Laryngeal Mask Airway general anesthesia combined epidural block cause mechanical damage vocal cords and airway, make the stress response light and the sense of rapid recovery, which is a safe and feasible method of anesthesia. Key words: LMA general anesthesia; epidural block; laparescopie; cholecystectomy
