Spinal anesthesia-induced hypotension: a risk comparison between patients with severe preeclampsia and healthy women undergoing preterm cesarean delivery.

We previously showed that, in comparison with term healthy parturients, patients with severe preeclampsia had a less frequent incidence of spinal hypotension, which was less severe and required less ephedrine. In the present study, we hypothesized that these findings were attributable to preeclampsia-associated factors rather than to a smaller uterine mass. The incidence and severity of hypotension were compared between severe preeclamptics (n = 65) and parturients with preterm pregnancies (n = 71), undergoing spinal anesthesia for cesarean delivery (0.

Chronobiology of labour pain perception: an observational study.

Background: Circadian variation may affect many biological and pharmacological phenomena.

Methods: To assess circadian variations in labour pain perception, 222 consecutive nulliparous women with uncomplicated pregnancy, spontaneous labour, cervical dilatation (3-5 cm), ruptured membranes and normal fetal heart rate tracings were studied. Visual analogue pain scores (VAPS) were analysed and divided into four periods: night (1:01 a.

Patients with severe preeclampsia experience less hypotension during spinal anesthesia for elective cesarean delivery than healthy parturients: a prospective cohort comparison.

In this prospective cohort study, we compared the incidence and severity of spinal anesthesia (SA)-associated hypotension in severely preeclamptic (n = 30) versus healthy (n = 30) parturients undergoing cesarean delivery. After the administration of IV fluids, SA was performed with hyperbaric 0.5% bupivacaine, sufentanil, and morphine.

[Dural puncture in obstetric analgesia. Epidemiologic features and therapeutic management].

Objective: To assess the time of occurrence, circumstances and presenting symptoms of unintentional dural puncture (UDP), the location and intensity of postdural puncture headaches (PDPH), and the efficacy of their treatment by epidural blood-patch (EBP).

Study Design: Cohort study.

Patients: Cases of UDP recorded over a 4-year period in an obstetric anaesthesia unit.

Intravenous nicardipine for severe hypertension in pre-eclampsia--effects of an acute treatment on mother and foetus.

Objectives: To assess the efficacy in lowering blood pressure, and the safety for mother and foetus of an acute nicardipine therapy in severe pre-eclampsia.

Design: Prospective clinical study.

Setting: One university hospital obstetric unit.
