General anesthesia for cesarean section at a tertiary care hospital 1990-1995: indications and implications.
Complications of general anesthesia for cesarean section remain the leading cause of anesthesia-related maternal mortality. General anesthesia, however, is becoming less popular for obstetric anesthesia, and thus fewer cesarean sections are conducted using this technique. As the number of general anesthesia cases decrease, the number of difficult intubations witnessed and managed by residents decreases. ⋯ Although the incidence of difficult intubations in those years ranged from 16.3% to 1.3%, only one failed intubation with resultant maternal mortality occurred. Few residency programs offer instruction on the difficult airway in the parturient population. Organized airway management programs specifically for the obstetric population may assist efforts to decrease the morbidity and mortality associated with the provision of general anesthesia for cesarean section.

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.

Severe mitral stenosis in a parturient with congestive cardiac failure and hypoglycaemia.
We report a case of maternal mortality in a 34-year-old multipara who presented at the 35th week of gestation with severe hypoglycaemia. She had no history of diabetes mellitus. This episode was a prelude to catastrophic and refractory congestive cardiac failure due to previously undiagnosed severe mitral stenosis. ⋯ She also developed deranged liver function with disseminated intravascular coagulation, which mimicked acute fatty liver of pregnancy. The problems of diagnosis and management are discussed. Unfortunately the patient died before mitral valvular commissurotomy could be effected.

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.
