A 35-week pregnant patient with ankylosing spondylitis and a known previous failed intubation required an elective caesarean section for intrauterine growth retardation. Regional anaesthesia was prevented by extensive spinal fusion. The anaesthetic management involved an awake oral fibreoptic intubation followed by induction and maintenance of general anaesthesia allowing delivery of a live infant without harm to the mother.

Combined spinal epidural anaesthesia: the single space double-barrel technique.
We present our own single-space method for performing combined spinal epidural anaesthesia. A spinal introducer and a Tuohy needle are sited in the same interspace. After insertion of the epidural catheter the introducer is used as a guide for a 25 gauge spinal needle. ⋯ The incidence of side effects (hypotension, nausea and vomiting, itching, post dural puncture headache) was comparable with those of other series. However, a high incidence (26.6%) of paraesthesiae during insertion of the spinal needle was noted. We suggest that this finding may be related to the use of pencil-point needles.

Epidural clonidine-fentanyl combination for labour analgesia: a comparison with bupivacaine-fentanyl.
This open study of 20 women compared epidural clonidine (300 microg)/fentanyl (100 microg) with bupivacaine (25 mg)/fentanyl (100 microg) in the provision of pain relief in labour. Sensory tests in the clonidine group revealed slight alterations in the appreciation of pin prick and temperature but motor power was unchanged. ⋯ Midwives also commented favourably on the normal mobility of these labouring mothers. There was no difference between the two groups in the duration of labour or the condition of the infants.

Acute tocolysis for suspected intrapartum fetal distress: maternal effects of terbutaline versus magnesium sulfate.
This study was undertaken to determine the maternal hemodynamic impact of terbutaline versus magnesium sulfate in the acute treatment of fetal distress prior to cesarean delivery. Forty-six women were prospectively randomized to receive 0.25 mg subcutaneous terbutaline or 4.0 g intravenous magnesium sulfate for in utero fetal resuscitation before cesarean delivery. ⋯ However, mean urine output was significantly greater in the terbutaline group (88 +/- 42 ml/h) than in those treated with magnesium sulfate (61 +/- 26 ml/h; P < 0.03). Terbutaline, the superior agent for acute tocolysis, is not associated with an increase in maternal cardiovascular side effects during anesthesia.

Sequential spinal epidural analgesia for pain relief in labour: an audit of 620 parturients.
This investigation was designed to evaluate sequential spinal epidural analgesia with a needle through needle technique for pain relief in labour. The spinal injection was made using a Becton Dickinson 29 gauge Quincke point needle. Bupivacaine 1 mg, sufentanil 5 microg and adrenaline 25 microg (2 ml) were injected intrathecally. ⋯ Of the 620 parturients in the investigation, 500 had a mean dose of 4.3 mg bupivacaine per hour. Hypotension and paresis were of no concern. Patient satisfaction was excellent, 85% of the parturients being very satisfied and 10% satisfied.
