Case ReportsCardiomyopathy in pregnancy and caesarean section: four case reports.
We present the clinical details of four women with cardiomyopathy who required caesarean section. Two women had peripartum cardiomyopathy and two had hypertrophic obstructive cardiomyopathy, one of whom has had two caesarean sections. ⋯ An incremental combined spinal-epidural technique with invasive monitoring was used for three women and one received general anaesthesia. The risks and benefits of different anaesthetic techniques are discussed.

Effect of nitrous oxide on propofol requirement during target-controlled infusion for oocyte retrieval.
Oocyte (egg) retrieval for in-vitro fertilization is a relatively short procedure, usually performed as an outpatient. Propofol is a suitable anesthetic agent. Target-controlled infusion is a recently developed system that aids rapid recovery from propofol anesthesia. This study sought to determine the target concentration of propofol required to prevent movement in 50% (Cp50) and 95% (Cp95) of women during oocyte retrieval, and investigated whether supplemental nitrous oxide (N2O) modified the Cp50 and Cp95. ⋯ The Cp50 value for target-controlled infusion propofol during oocyte retrieval was significantly reduced by a factor of 1.24 (95% CI 1.07-1.44) with the use of 50% nitrous oxide.
