A case is reported in which obstetric management resulted in 52 minutes elapsing between the induction of anaesthesia and delivery by Caesarean section. The mother was induced and maintained on Althesin and minimal methoxyflurane throughout this period without detriment to the neonate.

Fifty healthy mothers, with normal placental function, were anaesthetised with ketamine for Caesarean section. Anaesthesia was maintained with nitrous oxide, oxygen, muscle relaxants and controlled ventilation. Surgery was conducted in the lateral tilt position. ⋯ Unpleasant dreams were reported in 5 instances. In this study ketamine appeared to be unassociated with significant biochemical asphyxia, but may have been responsible for some element of drug induced neonatal depression. In view of our own experience and that of other workers, it is suggested that ketamine induction for Caesarean section should be re-evaluated using a lower dose of the drug.

[Our experience with pulsed oxygen and general anesthesia in direct suspension laryngoscopy].
The authors describe a group of 77 direct suspension laryngoscopies in which general anaesthesia and oxygen therapy were used. The technique is described in considerable detail. The catheter used is independent of the laryngoscope and is passed into the nasal cavity. ⋯ For the O.-R.-L. practitioner using the method, the advantages are as follows: induction anaesthesia is quicker than after neuroleptanalgesia, exposure of the larynx is excellent due to curarization and three endoscopies can be carried out in the same operation: laryngoscopy, oesophagoscopy and bronchoscopy. The disadvantage of general anaesthesia is that it makes it impossible to judge the mobility of the larynx. In 7,8 p. 100 of the cases, direct suspension laryngoscopy proved difficult or impossible to carry out fir anatomical reasons.
