The use of remifentanil infusion to facilitate epidural catheter placement in a parturient: a case report with pharmacokinetic simulations.
We present a case in which remifentanil infusion was used to provide analgesia during epidural catheter placement in a parturient who was experiencing great difficulty staying motionless because of extremely painful uterine contractions. Remifentanil may provide certain advantages in this setting, including improved analgesia during the procedure, briefer residual maternal and fetal (or newborn) drug effects after the procedure, and greater technical ease of catheter placement because of decreased movement induced by pain. Pharmacokinetic simulation of the dose administered suggests that analgesic effect-site concentrations can be rapidly produced, and that these concentrations decline rapidly to clinically insignificant levels after the infusion.

Continuous caudal analgesia in labour for a patient with Harrington rods.
We report the case of a 29-year-old patient who had Harrington rods inserted from T8 to L4 at the age of 14. She had been discouraged from having epidural anaesthesia in the antenatal clinic but, whilst in labour, requested analgesia in addition to Entonox and pethidine. Continuous caudal analgesia was commenced and provided good pain relief for labour and delivery.

Labour analgesia in a patient with carnitine palmityl transferase deficiency and idiopathic thrombocytopenic purpura.
We report a case of a woman with carnitine palmityl deficiency (CPT) and idiopathic thrombocytopenic purpura, presenting in active labour at 38 weeks gestation. We discuss different anaesthetic factors involved with both diseases, and we propose an optimal management of such cases. Neuraxial analgesia with minimal motor blockade is indicated in early labour because it is necessary to alleviate stress in order to avoid rhabdomyolisis associated with CPT deficiency. Neuraxial analgesia is also needed because the theoretical risk of performing a caesarean section is higher than in a normal population, first because labour must be kept as short as possible and secondly because the possible thrombocytopenic in the baby precludes the use of instrumental delivery.

Epidural analgesia in labour using intermittent doses determined by midwives.
Since 1985 midwives have been responsible for choice of drug and timing of epidural top-up doses for women in labour at Flinders Medical Centre. The midwife may choose from one of three different prescribed preparations, namely: bupivacaine 12.5 mg plus pethidine 25 mg, bupivacaine 25 mg, and bupivacaine 50 mg - each made up in a volume of 10 ml. This prospective study examined the incidence of adverse effects and level of patient satisfaction with midwife-managed epidural analgesia. ⋯ Women reported a high level of satisfaction with the overall experience of childbirth, though this was lower for instrumental and caesarean deliveries than for vaginal deliveries. On the other hand, satisfaction with pain relief provided by the epidural was greater in women who had caesarean or instrumental deliveries. The most commonly cited benefits of epidurals were good pain relief (83%), ability to cope (74%), feeling relaxed (67%), and being aware (60%), while feeling numb (23%) and experiencing severe pain at delivery (17%) were the most common causes of dissatisfaction.
