Epidural compared with general anaesthesia for caesarean delivery in conscious women with eclampsia

Fetomaternal outcome in severe preeclamptic women undergoing emergency cesarean section under either general or spinal anesthesia

This prospective observational study compared the effects of general and spinal anesthesia in 173 severe preeclamptic women undergoing emergency cesarean section. 146 (84.5%) patients underwent spinal anesthesia (SA) and 27 (15.5%) patients had general anesthesia (GA). Most of the patients were primigravid and nulliparous. Intraoperatively SA group required more intravenous fluid and vasopressor support, while GA group required more preoperative labetalol injection for blood pressure control. Overall 13.3% of patients required critical care, particularly GA group (44.4% versus 7.5%; P < 0.001). Patients receiving GA had a higher mortality (25.9% versus 1.4%; P < 0.001). The length of hospital stay was comparable. Significantly more neonates of patients receiving GA were found to be preterm (77.8% versus 44.5%; P < 0.01) and required advanced resuscitation. GA group also had higher neonatal mortality (29.6% versus 11%; P < 0.05). To conclude, severe preeclamptic mothers receiving general anesthesia and their babies required more critical care support. Maternal as well as neonatal mortality was significantly higher with general anesthesia.

Orofacial injuries associated with eclampsia in patients presenting at a Nigerian Tertiary Hospital

A prospective study was conducted to determine the incidence and pattern of orofacial injuries among eclamptic patients at the Lagos State University Teaching Hospital between December 2008 and November 2009. The incidence of orofacial injuries was 42%. Most injuries were due to bite and forceful insertion of hard objects into the patient's mouth by relatives during convulsive episodes. The type of antenatal care received had an influence on the incidence of orofacial injuries and there was a correlation between the number of convulsions and orofacial injuries. The mortality rate from eclampsia was 20.6%, and presence of orofacial injuries was a risk factor for mortality. Obstetricians and other healthcare providers should be familiar with the ways of preventing these injuries and seek early maxillofacial consultation when they occur. There is need for community education on the dangers of forceful insertion of hard objects into the mouth of eclamptics during fits.

Spinal anesthesia for lower segment Cesarean section in patients with stable eclampsia

STUDY OBJECTIVE

To report the use of spinal anesthesia in stable eclamptic patients.

DESIGN

Prospective case series.

SETTING

Emergency operating room of a metropolitan hospital.

PATIENTS

12 "stable" eclamptic parturients.

INTERVENTIONS

Subarachnoid block was instituted with hyperbaric 0.5% bupivacaine 1.7 mL with fentanyl 25 μg.

MEASUREMENTS

Intraoperative maternal hypotension, episodes of convulsion, the need to convert to general anesthesia, and Apgar scores at 1 and 5 minutes were recorded.

MAIN RESULTS

Only one of the 12 parturients had an episode of hypotension (treated by intravenous ephedrine), while no patient had a convulsion over the 48 hours after delivery. The sensory level achieved was T₅-T₆ and none of the cases was converted to general anesthesia. Median Apgar scores at 1 and 5 minutes were 8 and 9, respectively.

CONCLUSION

Spinal anesthesia avoided the known risks of general anesthesia and was not associated with any major complications.

A review of the management of eclampsia: practical issues

We reviewed 90 cases of eclampsia, an obstetric emergency associated with high blood pressure and convulsions, treated in two hospitals in Durban, South Africa. We present a protocol for the management of eclampsia based on this review and extensive clinical experience on this subject, which includes hemodynamic stabilization of the mother, prevention of recurrent convulsions, prompt delivery, and intensive monitoring in the immediate post-partum period.

Maternal and fetal outcome of anaesthesia for caesarean delivery in preeclampsia/eclampsia in Enugu, Nigeria: a retrospective observational study

BACKGROUND

Maternal mortality, for which preeclampsia is a major cause, is a problem in Nigeria. Accurate data are available for caesarean sections in the University of Nigeria Teaching Hospital, Enugu. We therefore studied the outcome of caesarean section among these high-risk patients.

METHOD

We conducted a retrospective survey of hospital records of patients with preeclampsia/eclampsia who had caesarean delivery in this unit over a four-year span from July 1998 to June 2002.

RESULTS

There were 3926 deliveries and 4036 births (3611 live births), with 898 women (23%) delivered by caesarean section. Of these, 125 (14%) had preeclampsia/eclampsia, 103 (82.4%) presenting for emergency caesarean delivery and 22 (17.6%) elective. General anaesthesia was used in 116 patients (92.8%) and spinal in nine. The major indications for surgery were severe preeclampsia/eclampsia in patients with unfavourable cervix (68%), fetal distress/intrauterine growth restriction (7.2%) and previous caesarean section (6.4%). There were six maternal deaths, all with general anaesthesia, giving a case fatality rate of 5.2% of general anaesthetics or 4.8% of caesarean deliveries. The cause of death was anaesthetic in three patients, cerebrovascular accident and pulmonary oedema in two and intraoperative haemorrhage in one. There were 13 stillbirths and 10 neonatal deaths.

CONCLUSION

Maternal and fetal mortality were high. Poverty, late presentation, lack of equipment and inexperienced management were major contributory factors. Use of spinal anaesthesia should be encouraged in view of recent favourable reviews and cheaper cost.

Anaesthetic dilemma: spinal anaesthesia in an eclamptic patient with mild thrombocytopenia and an “impossible” airway

We present our anaesthetic management of a 27-year-old woman with antepartum eclampsia, mild thrombocytopenia, difficult airway and clinical evidence of impending upper airway obstruction. She required urgent delivery by caesarean section, which was conducted uneventfully under spinal anaesthesia. We discuss the management conundrums presented by this case and why we chose spinal anaesthesia over other anaesthetic options.

Anaesthesia for non-scheduled caesarean delivery

In many countries there has been an increase in the number of women who deliver by caesarean section. This article reviews anaesthetic management of non-scheduled caesarean section. The choice of anaesthetic technique (regional anaesthesia versus general anaesthesia) is discussed and highlighted particularly from the viewpoint of urgency of operative delivery. A multidisciplinary approach is mandatory especially in emergency cases to prevent morbidity and mortality in mothers and neonates.
