Motor blockade during epidural anesthesia.

The effects of lumbar epidural anesthesia (LEA) on a previously described test of function of the rectus abdominalis muscle (the RAM-test) were compared with the effects of LEA on the Bromage test of muscle power in the hips and legs in 20 women having elective cesarean sections under LEA using 0.5% bupivacaine with epinephrine 1:200,000. The results showed no statistically significant correlation between the two tests. We conclude that zones of differential somatic motor blockade are present during LEA and that in obstetrics the RAM-test is the more appropriate test for evaluating the effects of LEA on somatic motor function. Use of the RAM-test is suggested in situations where one is interested in motor function of the abdominal wall muscles under LEA.

Long-term high frequency jet ventilation in a 3-year-old child.

Successful management of a large bronchopleural fistula in a 3-yr-old child with high frequency jet ventilation (HFJV) is described. Respiratory insufficiency in the child occurred secondary to hemophilus influenza pneumonia. After 7 days of conventional ventilatory support, a bronchopleural fistula occurred with massive lung collapse and subcutaneous and mediastinal emphysema. The child was ventilated with a high frequency jet ventilator for 37 days with resulting healing of the fistula. During ventilatory support with HFJV, no sedation or muscle relaxants were needed. Two problem areas in long-term support in children were discussed, namely, partial tube obstruction because of thick secretion and the need for proper humidification. A significant advantage of HFJV was the ability to superimpose it on spontaneous breathing with elimination of sedation or muscle relaxants.

Effect of anaesthesia for delivery on the weight of infants during the first 5 days of life.

Two hundred and forty-one neonates who had been delivered vaginally were selected randomly. The control group consisted of infants delivered without anaesthesia. In the study groups either extradural (mepivacaine, lignocaine or bupivacaine), spinal or general anaesthesia was administered. Each of the six groups was divided into breast- and bottle-fed subgroups. The results showed no significant difference in weight changes among the various groups. The bottle-fed subgroup showed less weight loss than the breast-fed subgroup (P less than 0.05). There was no interaction between method of feeding and type of anaesthesia.
