Anaesthetic management of vaginal delivery in a woman with Friedreich's ataxia complicated by cardiomyopathy and scoliosis.
We report the anaesthetic management of vaginal delivery in a woman with Friedreich's ataxia, who had hypertrophic cardiomyopathy and had previously undergone thoracic spinal fusion with Harrington rod fixation. Combined spinal-epidural analgesia was used. Options for the anaesthetic management of labour and delivery are discussed.

Epidural analgesia for term vaginal delivery after balloon valvotomy for mitral stenosis at 24 weeks gestation.
A woman presented at 24 weeks gestation with previously undiagnosed mitral stenosis. She did not respond to conservative management and underwent successful percutaneous balloon mitral valvotomy for refractory congestive cardiac failure, with complete resolution of her symptoms. The remainder of her pregnancy was uncomplicated and she delivered a healthy infant at 39 weeks gestation. An epidural block provided analgesia/anesthesia for vaginal delivery and repair of the perineal tear.

Randomized Controlled Trial Clinical TrialVolume preload: lack of effect in the prevention of spinal-induced hypotension at caesarean section.
A randomized double-blind study of 40 women was performed to compare blood pressure changes between two groups of women following induction of spinal anaesthesia for elective caesarean section. One group received a 1 L Ringer's solution preload, administered over 10 min, before spinal anaesthesia while the other group received no preload. ⋯ There were no differences between the groups in terms of neonatal outcome as assessed by Apgar score, umbilical arterial and venous blood pH, and Neonatal Adaptive Capacity Scores. When ephedrine is infused prophylactically immediately following spinal anaesthesia for elective caesarean section, a 1000 ml crystalloid preload confers no advantages in terms of maternal blood pressure control or neonatal outcome.

Maternal temperature during labour using low-dose (ambulatory) epidural analgesia with bupivacaine and fentanyl.
Maternal temperature is known to increase during labour with conventional epidural analgesia mixtures. To date, the effect of newer low-dose (ambulatory) epidural concentrations on maternal temperature has not been studied. Twenty-six women in established labour received epidural analgesia with 0.1% bupivacaine and 2 microg/ml fentanyl. ⋯ There was no significant overall rise in maternal temperature during labour with the use of an ambulatory epidural mixture. One patient exhibited an increase in temperature of 0.8 degrees C to 38 degrees C after 720 min and another of 1.1 degrees C to 38.1 degrees C after 630 min. We conclude that, whilst overall maternal temperature does not increase following low-dose epidural analgesia, individual increases may still occur after 10 h.
