Complications of cesarean deliveries: rates and risk factors

Does relaxation education in anxious primigravid Iranian women influence adverse pregnancy outcomes?: a randomized controlled trial

Maternal anxiety and stress are found to be predictors of adverse pregnancy outcomes, including low birth weight and prematurity.

OBJECTIVE

The aim of the study was to determine whether relaxation education in anxious pregnant Iranian women in their first pregnancy affects selected pregnancy outcomes, including birth weight, preterm birth, and surgical delivery rate.

SUBJECTS

A total of 110 obstetrically and medically low-risk primigravid women in Iran with a high anxiety level demonstrated by Spielberger's State-Trait Anxiety Inventory were randomly assigned into experimental and control groups.

METHOD

In this randomized controlled trial, the experimental group received routine prenatal care along with 7-week applied relaxation training sessions, while the control group received only routine prenatal care. Anxiety and perceived stress were measured by pre-educational and post-educational intervention. Data related to pregnancy outcomes include birth weight, gestational age at birth, and type of delivery.

RESULTS

Significant reductions in low birth weight, cesarean section, and/or instrumental extraction were found in the experimental group compared with the control group. No significant differences were found in the rate of preterm birth.

CONCLUSION

The findings suggest beneficial effects of nurse-led relaxation education sessions during the prenatal period. This intervention could serve as a resource for improving pregnancy outcomes in women with high anxiety.

A double blind, randomized trial on augmentation of labour with a combination of intravenous propranolol and oxytocin versus oxytocin only

OBJECTIVE

To compare the combination of intravenous propranolol and oxytocin with oxytocin only in augmentation of labour.

STUDY DESIGN

A prospective randomized double-blind study in an obstetric department of a large university hospital in Finland. A total of 107 parturients with arrested first stage of labour owing to inadequate uterine contractility were randomized to receive intravenously once or twice a 2 mg dose of propranolol or placebo combined with oxytocin infusion. The main outcome measure was the effect of intravenous propranolol on the frequency of Caesarean section among parturients with arrested labour. The secondary outcome measures were the duration of labour, the required dosage of oxytocin, CTG readings, neonatal outcome and maternal and cord plasma levels of beta-adrenoceptor-binding component of propranolol. Categorial variables between the groups were compared using Chi square and Fisher's exact tests. Continuous variables were compared using the Mann-Whitney U-test and Student's t-test.

RESULTS

No reduction in Caesarean section rate was found in the propranolol group. Seventy-three percent of the parturients in the propranolol group and 85% in the placebo group had spontaneous vaginal delivery, RR=0.86 (95% CI 0.70-1.05). The percentage proportion of the augmented part of labour was significantly shorter in the propranolol group than in the placebo group. No differences in the required oxytocin dosage or CTG pathology were found between the groups. Propranolol was found to be safe for the neonates. The concentrations of its beta-adrenoceptor-binding component after a 2mg intravenous dose were quite similar in parturients and neonates at the time of delivery. The active drug component crossed placental barriers with an average neonate umbilical artery/parturient venous plasma ratio of 0.7. After a 4 mg dose the active drug concentrations in parturients were rather similar to those measured after 2 mg dose, whereas in neonates there were signs of drug accumulation. No picture could be obtained from the kinetics of the beta-adrenoceptor-binding component of propranolol from the data.

CONCLUSIONS

Propranolol (2 or 4 mg i.v.) combined with oxytocin, as treatment for arrested labour did not affect the Caesarean section rate compared with placebo plus oxytocin. The percentage proportion of the augmented part of labour was significantly shorter after propranolol. Propranolol was safe for the neonates and can be used as an additional medication among parturients with arrested labour.

Epidural Anesthesia for Elective Cesarean Delivery with Intraoperative Arterial Occlusion Balloon Catheter Placement

Obstetric hemorrhage is a leading cause of maternal mortality. We describe the anesthetic management of elective cesarean delivery in patients at high risk for hemorrhage. The utility and limitations of intraarterial balloon catheter placement and epidural anesthesia are described.

Risk factors for post-partum complications occurring after preeclampsia and HELLP syndrome. A study in 453 consecutive pregnancies

OBJECTIVE

To evaluate complications that occurred during the post-partum period for patients with preeclampsia or HELLP syndrome.

STUDY DESIGN

Retrospective analysis of 453 patients. The main outcome measures were maternal complications during post-partum period: fever >38.5 degrees C with proved infection, abdominal or perineal abscess, thrombo-embolic events, reoperation, need for blood transfusion, acute renal failure, eclampsia or disseminated intravascular coagulation. Statistic tests included univariate and multivariate analysis with stepwise descending logistic regression.

RESULTS

Patients were divided into 305 preeclampsia (67.3%) and 20 HELLP syndrome (4.4%), 128 (28.3%) had both. Eighty-five patients (18.8%) had at least one post-partum complication. The most frequent complication was infection: fever (41 patients, 9.1%) and abscess (30 patients, 6.6%). Twenty-six transfusions (5.7%), 10 disseminated intravascular coagulation (2.2%), seven thromboembolic events (1.5%), seven reoperations (1.5%) and one eclampsia (0.2%) were observed. There was no acute renal failure, no pulmonary oedema and no maternal death. Stepwise logistic regression showed five independent risk factors associated with post-partum complications: ascites or pulmonary oedema (OR: 1.84, 95% CI: 1.01-3.37), platelet count <100000/mm3 (OR: 1.96, 95% CI: 1.18-3.26), serum acid uric >360 micromol/l (OR: 2.36, 95% CI: 1.22-4.52), serum creatinine >120 micromol/l (OR: 2.99, 95% CI: 1.32-6.78), and proteinuria >5 g/l (OR: 1.80, 95% CI: 1.06-3.05).

CONCLUSION

We conclude that severity criteria for preeclampsia or HELLP syndrome combined with caesarean section increased the risk of complication during the post-partum period.

Timing of prophylactic antibiotic administration in the uninfected laboring gravida: a randomized clinical trial

OBJECTIVE

The purpose of this prospective study was to determine whether the timing of prophylactic antibiotics at cesarean delivery influences maternal/neonatal infectious morbidity.

STUDY DESIGN

In this double-blind placebo-controlled trial, cefazolin was given at skin incision (group A) or at cord clamping (group B). Patients were eligible for the trial if they had labored and required a cesarean delivery.

RESULTS

Over a 30-month period 303 patients with singleton pregnancies entered the trial; 153-group A, 149-group B. Demographics, indication for cesarean delivery (P = .54), and operative time (P = .999), as well as rates of endometritis (RR 0.67, 95% CI 0.42-1.07), wound infection (RR 0.84, 95% CI 0.45-1.55), neonatal sepis (RR 1.28, 95% CI 0.91-1.79), and NICU admissions (RR 1.28, 95% CI 0.91-1.79) were similar between the 2 groups.

CONCLUSION

There was no difference in maternal infectious morbidity whether antibiotics were given before skin incision or at cord clamping.

Can cesarean section be performed without the woman's consent?

Occasionally, an obstetrician can experience conflicts between the mother and her fetus. In a situation where the life of the fetus is in danger, religious, cultural, or other convictions may cause the mother to refuse the physician's recommendations for delivery. When there is a medical indication to perform cesarean section, but the mother refuses, has the obstetrician then a right to perform a cesarean section to save the fetus from possible death or serious injury? In 1987, The Norwegian Directorate of Health made a statement on cesarean section without consent, but later, new legislation on patient rights has been introduced. In Norway, no scientific medical articles have been published on this topic, and no cases have yet been brought to court. Cases of court-ordered cesarean section have been reported from the UK and the USA. In this report, we discuss some of the ethical, moral, and legal aspects of forced cesarean sections.
