Randomized Controlled Trial Clinical TrialRegional anaesthesia for caesarean section in severe preeclampsia: spinal anaesthesia is the preferred choice.
Standard textbooks advocate epidural rather than spinal anaesthesia for caesarean section in severe preeclampsia. The basis for this recommendation is the theoretical risk of severe hypotension but no published scientific studies have been identified to support this assertion. We therefore designed a prospective study to compare spinal versus epidural anaesthesia in severely pre-eclamptic patients requiring hypotensive therapy. ⋯ By contrast in the epidural group three patients had mild pain and four others had pain severe enough to warrant intraoperative analgesia. There were no differences in neonatal outcomes. These findings support recent studies suggesting the safety and efficacy of spinal anaesthesia in this group of patients.

Randomized Controlled Trial Clinical TrialPain during elective caesarean section under epidural anaesthesia: the effect of a 10 degrees head-up tilt position.
One hundred patients scheduled for elective caesarean section under epidural anaesthesia were randomized to have epidural loading doses in either the horizontal or a 10 degrees head-up position. They were assigned to their position only after an initial dose of 4 ml of 0.5% bupivacaine had been given. Ten minutes after this dose they were given 10 ml of 0.5% bupivacaine and 50 microg of fentanyl in their allocated position. ⋯ The inter-quartile range was 0 to 2 for the head-up tilt position and 0 to 4 for the horizontal position (P<0.05). Position had no significant effect on the blood pressure or Bromage score. A 10 degrees head-up tilt position is useful during the establishment of epidural anaesthesia to reduce the pain experienced by the patient during caesarean section.

Angioneurotic oedema is a rare disease caused by Cl esterase inhibitor deficiency. Hereditary angioneurotic oedema includes type I (quantitative and functional) deficiency and type 11 (functional) deficiency. Its prophylactic treatment during pregnancy, based on danazol therapy if the fetus is male, may avoid acute attacks of generalized or laryngeal oedema. ⋯ Regional analgesia is indicated for labour or caesarean section to prevent pain and stress and to avoid the difficulties associated with laryngeal oedema and tracheal intubation. In the treatment of an acute attack, Cl esterase inhibitor concentrates (1500 units) may be given i.v. We present two cases, one of hereditary and one of acquired angioneurotic oedema, both presenting during pregnancy and both delivered vaginally under epidural analgesia with successful outcome.

Necrotising fasciitis and group A streptococcus toxic shock-like syndrome in pregnancy: treatment with plasmapheresis and immunoglobulin.
A 30-year-old woman at 25 weeks gestation presented to the labour ward complaining of abdominal pain and a painful bruise in her right groin. Over the course of several hours, she developed rapidly spreading necrotising fasciitis of the right thigh. She required emergency radical debridement of the thigh and caesarean delivery of a dead fetus. ⋯ Despite the development of acute renal failure, acute respiratory distress syndrome and a left hemiplegia, the patient made a remarkable recovery. She was later transferred to a plastic surgical unit for split skin-grafting. The importance of early diagnosis and aggressive treatment of GAS TS-LS is emphasized and the place of plasmapheresis and intravenous immunoglobulin therapy in this condition is discussed.

Preeclampsia/eclampsia affects only a small proportion of all pregnancies, yet accounts for much of the obstetric morbidity and mortality seen in the USA and UK. A full understanding of preeclampsia/eclampsia, its variable presentation and complex pathophysiology allows the consulting anesthesiologist to optimize a plan for anesthetic management of the afflicted patient.
