Abstract

|
|
The occurrence of cardiac arrhythmias and changes in pulse rate and blood pressure during mask anesthesia with enflurane was investigated in 80 patients with special reference to the influence of atropine 0.01mg. Kg-1 5 min. before anesthesia and thiopental. The average duration of mask anesthesia was a little less than 1 hr in all groups. Nodal arrhythmias were significantly more common in the atropine group than in the non-atropine groups. Following atropine administration heart rate very increased whereas very slightly increases were seen in the non-atropine groups. Blood pressure fell at the induction but was almost back to normal at 1 hr after induction. Blood pressure was unaffected by atropine. Slightly lower values of blood pressure were suggested in the thiopental groups, whereas thiopental did not modify cardiac rhythm or pulse rate. Suction of the pharynx was necessary in only one case. In conclusion, the present study does not support the routine administration of atropine before enflurane anesthesia with or without thiopental induction.
