Randomized Controlled Trial Clinical TrialAlternating patient position following the induction of obstetric epidural analgesia does not affect local anaesthetic spread.
To assess the influence of gravity on epidural-induced sensory blockade during the first stage of labour, 60 parturients were recruited to a randomized, controlled, single-blinded study. In all cases an epidural catheter was placed with the patient in the left lateral position. Thereafter, patients were randomized to one of three groups. ⋯ Time to maximal block was 14.7 +/- 2.3 min, 14.1 +/- 1.6 min and 13.9 +/- 1.5 min for groups L, L+R and S respectively. After maximal blockade, pain scores were significantly (P<0.0001) decreased in all groups, with no differences between them. We conclude that position immediately following local anaesthetic drug administration has little effect on onset and distribution of epidural analgesia.

Day case transvaginal ultrasound-guided needle puncture is currently the method of choice for oocyte retrieval. The risk of morbidity from this procedure increases with sudden patient movement in response to needle manipulation. ⋯ The aim of this pilot study was to establish whether spinal analgesia using a mixture of bupivacaine and fentanyl could be useful in this context. The results identify several advantages of this technique over current clinical practice, and merit further comparative investigation.

Randomized Controlled Trial Clinical TrialComparison of three different loading doses to establish epidural analgesia in labour.
Women requesting epidural analgesia were randomized to receive one of three loading doses. Group 1 received a single dose of bupivacaine 9.375 mg (15 ml of 0.0625%) containing fentanyl 37.5 microg and adrenaline 37.5 microg group 2 received a single dose of bupivacaine 15 mg (15 ml of 0.1%) containing fentanyl 30 microg and adrenaline 30 microg and group 3 received a test dose of bupivacaine 10 mg (4 ml of 0.25% - test) followed 5 min later by bupivacaine 20 mg (8 ml of 0.25% - loading). ⋯ Speed of onset of analgesia was the same in all three groups, with the majority of women achieving satisfactory analgesia by 20 min. Motor block was significantly increased in group 3 at 30 min, but by 1 h there was no difference in motor block between the groups.

We report a case of meningitis developing a number of days after a subarachnoid block for caesarean section. No organisms were grown but the clinical picture was suggestive of bacterial meningitis, the clinical course of which had been modified by the administration of antibiotics for presumed wound infection. The possible aetiology is discussed.

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.
