A retrospective audit of obstetric epidurals was performed at Royal Surrey County Hospital. The aim was to determine the efficacy of epidural blood patch in the management of post-dural puncture headache following inadvertent dural puncture in the obstetric population, over a 5-year period between March 1993 and February 1998. ⋯ Following treatment with one epidural blood patch, 33% of patients obtained complete and permanent relief, 50% partial relief and 12% no relief. Twenty-nine percent of patients required a second epidural blood patch of which 50% were completely successful, 36% were partially successful and 14% gave no relief.

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.

Anesthesia for reduction of uterine incarceration: report of two cases.
We present two cases in which anesthesia was needed for the reduction of uterine incarceration. The first case was managed with a combined spinal/epidural technique and the second with a single intrathecal injection of opioid and low dose local anesthetic. The anesthetic issues pertinent to the reduction of an incarcerated uterus are discussed and the literature briefly reviewed.

Post partum creatine phosphokinase and its muscle-brain isoenzyme elevation and transient Q-wave in a patient with idiopathic hypertrophic subaortic stenosis.
A primigravida with idiopathic hypertrophic subaortic stenosis, New York Heart Association Classification III, developed acute chest pain with significant ST segment depression together with a new Q-wave in chest lead V6 on the electrocardiograph following delivery under lumbar epidural analgesia. An intrapartum myocardial infarct was suspected because serial creatine phosphokinase and its muscle-brain isoenzyme levels were elevated in the postpartum period. ⋯ Consequently, the elevations of creatine phosphokinase and its muscle-brain fraction alone are not diagnostic of myocardial infarction in the postpartum period. The diagnosis of myocardial infarction must be based on the clinical picture, serial electrocardiogram recording and determination of lactate dehydrogenase and aspartate amino transferase.

Are women requiring unplanned intrapartum epidural analgesia different in a low-risk population?
We studied 645 full-term low-risk women in early labour in 6 units to evaluate the effects of maternal characteristics and obstetric management in early labour on the use of epidural analgesia, and to analyse the relationship between epidural analgesia, progress of labour and mode of delivery using multiple logistic regression. Among variables present in early labour, nulliparity, ethnicity and obstetric unit were the strongest predictors of epidural analgesia requirement. In nulliparous women, obstetric unit affected use of epidural analgesia (P<0.05) and induction of labour was associated with increased use of epidural analgesia (odds ratio 3.45, 95% CI: 1.45-7.90). ⋯ Furthermore, rate of cervical dilation was similar in the non epidural group throughout the first stage (mean 3.41 cm/h, 95%CI: 3.19-3.63) and in the epidural group after epidural analgesia decision (mean 3.99, 95% CI: 2.96-5.02), while the mean cervical dilatation rate before epidural analgesia was 0.88 cm/h (95% CI: 0.72-1.04). The need for epidural analgesia is, therefore, multifactorial and difficult to predict. Whereas nulliparity increases epidural analgesia requirement, data on the progress of labour before pain relief suggest that epidural analgesia is a marker of pain severity and/or labour failure rather than the cause of delayed progress in low-risk pregnancies.
