Low dose intrathecal morphine and pain relief following caesarean section.
Healthy women who underwent caesarean section under spinal anaesthesia were studied to determine the extent of postoperative analgesia and side-effects produced by low doses of intrathecal morphine. Patients were randomly allocated to receive, in double-blind fashion, 0 mg (group 1: control group), 0.05 mg (group 2), 0.1 mg (group 3), or 0.2 mg (group 4) of morphine, with 10 mg tetracaine in 10% dextrose 2.5 ml. (n = 20 x 4 groups). The effect of intrathecal morphine was examined in terms of the duration until the first supplemental analgesic was needed and the numbers of the doses within the first postoperative 48 h. ⋯ No patient developed respiratory depression. Our results suggest that postoperative analgesia lasts more than 24 h with 0.1 mg or 0.2 mg of intrathecal morphine. Since the incidence of side-effects was higher at 0.2 mg, 0.1 mg may be the optimum dose for caesarean section.

Continuous electrocardiographic monitoring was performed in 20 term parturients during labor, vaginal delivery, and recovery. Mean duration of monitoring was 13.37 h. ⋯ Eight patients exhibited premature ventricular contractions or supraventricular tachycardia. ST-segment depression was noted in 3 patients (15%); in all 3, this was concurrent with maximum heart rate, was not associated with any symptoms, and occurred in the post-partum period.

The experiences of 890 parturients were studied across Finland during one week to determine how they experienced labour pain and how effective they regarded the means to alleviate it. The majority of women (72%) had been afraid of labour and 88% had intended to request some pharmacological pain relief. 84% of primiparous and 72% of multiparous rated their pain severe or unbearable. Epidural analgesia was found to be the most effective method in the first stage of labour, but in the second this superiority was no longer apparent. Unfortunately, it seems to be readily available only during office hours in spite of the fact that the majority of deliveries happen outside of that time.

Pregnancy and cirrhosis: management of hematemesis by Warren shunt during third trimester gestation.
Considerable pathophysiologic changes accompany cirrhosis. Elevation of portal venous pressure predisposes to esophageal varices and hematemesis. ⋯ The anesthetic management of a pregnant cirrhotic patient for a Warren shunt is complicated by concerns for pre-existing hepatic dysfunction and pregnancy-induced physiologic changes as well as fetal well-being. The management of such a case is reviewed and relevant pathophysiology discussed.
