Cesarean section with regional anesthesia using an extendable epidural block

Epidural analgesia was used for 86 deliveries by cesarean section. The placement of a catheter in the epidural space allowed adjustment of the extent of the block so that supplementary analgesia was required in only six patients. Continuous fetal heart rate monitoring was of practical clinical value, especially in treating maternal hypotension. Symptomatic hypotension was avoided or corrected by the intravenous infusion of Hartmann's solution and by the use of a lateral tilt of the operating table. Eleven patients had a blood pressure of less than 100 mm Hg, and in three of these, there was an adverse effect on the fetal heart trace.
