Effect of anesthesia for primary cesarean section on postoperative infectious morbidity.
It has been stated that general anesthesia is a risk factor for postcesarean infectious morbidity. A retrospective review of 252 women who had undergone primary cesarean section at the University of Iowa Hospital was conducted. Regional anesthesia was successfully administered to 170 patients, and general anesthesia was administered to 82 patients. ⋯ There were no statistically significant differences between the two groups with regard to multiple indexes of postoperative fever or infection, including febrile morbidity, diagnosis of infection, use of therapeutic antibiotics, fever index, and postoperative hospital stay. General anesthesia, as administered to patients in the present series, did not increase the risk of infectious morbidity after primary cesarean section. However, our surgeons apparently were influenced by the choice of anesthetic technique when selecting a skin incision.

To compare postoperative well-being after general and epidural anaesthesia, 58 women undergoing Caesarean section were divided into a general anaesthetic group receiving intramuscular opioid postoperatively (26), and an epidural group receiving morphine via the epidural route (32). The epidural group required less analgesia (p less than 0.01 at 0.5 and 8 hours, p less than 0.001 at 4 hours). There was no difference in the use of oral analgesics. ⋯ More in the epidural group had a very good night's sleep during each night studied. Patients in the epidural group were slower to use the ward toilet (p less than 0.01) and had more itching (p less than 0.001). Our conclusion is that patients progressed well in both groups.

Relationship between methaemoglobin production and methylene blue plasma concentrations under general anaesthesia.
Recently, a family tree with a predisposition for the gene of multiple endocrine neoplasia Type 1 has been identified in Tasmania. As the surgical identification and localisation of parathyroid adenomas is facilitated by the administration of methylene blue, an opportunity has presented to measure the plasma concentration of methylene blue and methaemoglobin production. ⋯ Mean peak methylene blue concentrations of 3.72 micrograms l-1, mean percentage methaemoglobin of 10.0 and a PaO2 within acceptable clinical ranges were found. No apparent relationship between methylene blue concentration and methaemoglobin production was found.

Case ReportsAsystole and bradycardia in adult patients after a single dose of suxamethonium.
Two cases of cardiac asystole and one case of severe bradycardia were seen following a single injection of suxamethonium in a series of 46 adult patients in whom anaesthesia was induced with fentanyl and etomidate. It is suggested that the vagomimetic effects of fentanyl and, possibly also of etomidate, may contribute to the enhancement of the bradycardic effects of suxamethonium.
