[Influence of epidural anesthesia on the halothane MAC-intubation in emergence in infants and children].
The alveolar anesthetic concentration level at which the patient first shows movement when emerging from anesthesia is defined as MAC-intubation in emergence in infants and children. Twenty one patients of ASA physical status 1, were studied to determine the halothane MAC-intubation in emergence. The patients were divided into two groups; a general anesthesia alone group and a general anesthesia plus epidural anesthesia group. ⋯ The time from the discontinuation of halothane to the first body movement tended to be longer without epidural anesthesia. RR and ETCO2 did not differ between the two groups of patients. The halothane MAC-intubation in emergence in the general anesthesia alone group was 0.26%, and adding epidural anesthesia decreased this concentration to 0.18%.
