Alpha-adrenergic responsiveness correlates with epinephrine dose for arrhythmias during halothane anesthesia in dogs.
The dose of epinephrine required to elicit ventricular arrhythmias during halothane anesthesia may depend on end-organ sensitivity. We determined whether the arrhythmogenic dose for epinephrine (ADE) could be correlated with either alpha- or beta-adrenergic responsiveness. After ADE was determined in 26 dogs anesthetized with 1.2 MAC halothane, an in vivo assessment of adrenergic responsiveness was made. ⋯ The correlation coefficients for alpha 75 and beta 75 vs ADE then were determined by multiple linear regression analysis. There was a highly significant correlation with the alpha 75 (F = 9.06; P less than 0.01), while no relationship existed with beta 75 (F = 0.52; P greater than 0.05). Thus the alpha-adrenergic responsiveness in individual patients may be used to predict the threshold for epinephrine-induced arrhythmias during halothane anesthesia.

ReviewGeneral anesthesia in cesarean section: effect on mother and neonate.
Advances in anesthetic techniques during the past several decades have resulted in an excellent outcome in infants delivered by cesarean section under general anesthesia. To understand these results, it is important to be familiar with the physiologic changes which occur during general anesthesia. A review of the literature which focuses on the findings which led to current anesthetic principles is presented.

Comparative Study
Anaesthetic morbidity following caesarean section under epidural or general anaesthesia.
To find out whether morbidity in the first postoperative week is affected by type of anaesthetic technique, healthy patients who had caesarean sections under epidural anaesthesia were compared with those who were given a general anaesthetic. Epidural anaesthesia was associated with less pain (p less than 0.00001) and discomfort in the immediate postoperative period. ⋯ Fewer mothers were coughing (p less than 0.005), had fever (p less than 0.01), or felt tired and depressed (p less than 0.005) by the sixth postoperative day after epidural caesarean section. The epidemiology of anaesthetic morbidity needs to be assessed in other surgical patients.
