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.

Neonatal effects of patient-controlled analgesia using fentanyl in labor.
Patient-controlled analgesia (PCA) has been used at our institution for the past 5 years, as an alternative labor analgesic when epidural analgesia is contraindicated. This retrospective study evaluates the effects of maternal PCA fentanyl on infants of greater than 32 weeks gestational age. The neonatal charts (n=32) were reviewed for birth weight, gestational age, 1 min and 5 min Apgar scores, use of naloxone and umbilical venous gases. ⋯ Three infants with a 1 min Apgar of 4 required naloxone. The total fentanyl received by mothers of infants who required naloxone was significantly higher than the group of mothers whose infants did not require naloxone (770 +/- 233 microg vs 298 +/- 287 microg, P = 0.027) Use of PCA fentanyl in this high-risk obstetric population was associated with a 44% incidence of moderately depressed neonates with an Apgar score

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.

Severe urticaria and pregnancy: use of the Internet to aid management.
A case of severe urticaria complicating pregnancy is described. Advice was sought and received from experts in the condition, using the Internet to exchange information. Epsilon-aminocaproic acid (EACA) was used with no apparent adverse effects. This case report highlights some of the problems of management of thi rare condition in pregnancy and obstetric anaesthesia, and the potential benefit of the Internet and its user groups.
