Randomized Controlled TrialDose response to intrathecal diamorphine for elective caesarean section and compliance with a national audit standard.
This double-blind randomised controlled trial investigated the most appropriate dose of intrathecal diamorphine to use with high-dose diclofenac as part of a multimodal analgesic regimen for caesarean section under subarachnoid block. We also wished to establish whether it was possible to satisfy the Royal College of Anaesthetists postoperative pain audit recommendation for this patient group. ⋯ We found that for elective caesarean section under subarachnoid block with high dose diclofenac, analgesia was optimal with 300 microg of intrathecal diamorphine. Even the highest dose of intrathecal diamorphine did not achieve the Royal College of Anaesthetists postoperative audit target that 90% of patients should have a pain score of no more than 3/10. We believe that this target is too arduous.

Review Case ReportsUse of recombinant activated factor VII in massive obstetric haemorrhage.
Massive obstetric haemorrhage is a life-threatening emergency that remains a major cause of maternal mortality. Conventional management is aimed at optimising uterine tone, replacing circulating volume and blood products, and surgery to achieve haemostasis. ⋯ We report our experience of using it in the treatment of major post-partum haemorrhage in four previously healthy parturients. The published reports of recombinant activated factor VII use in post-partum haemorrhage (unrelated to pre-existing coagulopathies) are compared.

Sensitization to latex seems to occur more frequently in women than in men. Obstetric and gynecological surgical procedures have recently been shown to be a common setting for latex anaphylaxis. We analyzed all the cases of anaphylactic reactions during 1240 cesarean sections in 2004; the patients were questioned for risk factors and underwent allergy testing for drugs and latex. ⋯ If latex allergy is confirmed or strongly suspected, patients should be managed in a latex-safe environment. Premedication with antihistamines and steroids might be useful to further reduce the risk. After the delivery, specific desensitization may represent a good therapeutic option.

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.
