Impact study of the introduction of low-dose epidural (bupivacaine 0.1%/fentanyl 2 microg . mL(-1)) compared with bupivacaine 0.25% for labour analgesia.
We conducted a retrospective analysis of the obstetric effects of introducing a low-dose epidural regimen for epidural analgesia in labour. Before this, all women in our unit requesting epidural analgesia for labour received intermittent boluses (10 mL) of 0.25% bupivacaine. After the introduction of the low-dose service in March 2000, intermittent boluses (10 mL) of 0.1% bupivacaine with fentanyl 2 microg . mL(-1) were given. ⋯ Maternal satisfaction was high in both groups (95 and 97%, respectively). We conclude that the introduction of a low-dose regimen of epidural analgesia for labour reduces the incidence of instrumental deliveries. It also decreases the incidence of bladder catheterisation during labour, but the need for anaesthetic intervention may be greater.

Regional blockade for delivery in women with scoliosis or previous spinal surgery.
We conducted a prospective observational study between 1992 and 2001 identifying obstetric patients with untreated or surgically corrected scoliosis or lumbar-sacral fusion surgery. The regional techniques for labour and delivery that were offered were epidural analgesia, combined spinal epidural anaesthesia (CSE), single shot spinal or continuous spinal anaesthesia (CSA) depending on the degree of scoliosis, previous surgery, cardio-respiratory compromise and planned mode of delivery. Forty women were included in the study, one woman with two separate deliveries, giving 41 cases for analysis. ⋯ From a total of 19 CSA techniques attempted sixteen catheters were successfully inserted and produced good analgesia or anaesthesia for vaginal or operative delivery in 12 women (63%). There was one case of post dural puncture headache following a CSA for labour and delivery. We discuss the choices available for regional anaesthetic techniques in scoliotic women and the relative merits of each.

Preeclampsia complicated by placental abruption, HELLP, coagulopathy and renal failure - further lessons.
We present a case of preeclampsia complicated by HELLP (haemolysis, elevated liver enzymes and low platelets) syndrome and marked coagulopathy. The severity of the coagulopathy and haemolysis made renal failure and pulmonary oedema inevitable. ⋯ These were the delay to appreciate the haemolysis, the severity of the haemolysis and its interaction with the treatment of coagulopathy and the conservative management of pulmonary oedema. At these points there were shortcomings in our management of this complex case that merit further discussion.

We present our experience in the anesthetic management of two parturients with pseudoxanthoma elasticum. The first had an epidural catheter inserted for labor analgesia and ultimately had a forceps delivery. ⋯ There were no untoward effects of regional anesthesia in either of these two women. The anesthetic implications for parturients with pseudoxanthoma elasticum are discussed.
