Magnesium and bupivacaine-induced convulsions in awake pregnant rats.
Magnesium sulfate (MgSO(4)) is widely used for the treatment and prevention of convulsions associated with preeclampsia. The aim of this study was to determine whether it alters the dose of bupivacaine required to produce convulsions in awake pregnant rats. ⋯ This study demonstrates that the clinically used concentration of magnesium sulfate increased the threshold of bupivacaine-induced convulsions in awake rats.

Use of anaesthetic rooms in obstetric anaesthesia; a postal survey of obstetric anaesthetists and departments in the United Kingdom.
Use of anaesthetic rooms has been much discussed in the UK in recent years, but attitudes and practices of obstetric anaesthetists regarding their use for caesarean section have never been sought. ⋯ The majority of obstetric anaesthetists have abandoned the use of anaesthetic induction rooms, the main reason being patient safety. For the same reason, two-thirds of departments providing obstetric anaesthesia consider induction of anaesthesia in the operating room their standard practice.

Some immediate serious complications of obstetric epidural analgesia and anaesthesia: a prospective study of 145,550 epidurals.
Inadvertent intravascular, intrathecal or subdural injection in obstetric regional analgesia are potentially life-threatening, so following a catastrophic complication it was decided to collect data regionally. ⋯ The incidence of intravascular, intrathecal and subdural injection and of high or total spinal block was similar to that found in previous prospective studies in obstetric and non-obstetric patients. The incidence of these complications has not changed and is not related to the number of deliveries or the epidural rate in obstetric units.

Case ReportsAnaesthetic management during labour of a manifesting carrier of Duchenne muscular dystrophy.
We describe the peripartum anaesthetic management of a 36-year-old woman who was a manifesting carrier of Duchenne muscular dystrophy. Duchenne muscular dystrophy is an X-linked recessive disorder affecting young males associated with severe complications during anaesthesia if depolarising neuromuscular blocking drugs and volatile agents are used. ⋯ We planned to establish regional anaesthesia should an operation be necessary during labour or delivery and to use propofol total intravenous anaesthesia and rocuronium if general anaesthesia became unavoidable. At 37 weeks, the woman went into spontaneous labour, but fetal distress necessitated caesarean section for which combined spinal-epidural anaesthesia was used.
