The use of prostaglandin E₁ in peripartum patients with asthma

Pulmonary disorders in pregnancy: Bronchiectasis, cystic fibrosis, sarcoidosis and interstitial diseases

This chapter aims to provide expert guidance to obstetricians, general practitioners, allied health staff and women with lung disease about the interactions between pregnancy and different lung diseases. This chapter will cover other airway diseases such as bronchiectasis and cystic fibrosis (CF) together with sarcoidosis and interstitial lung disease (ILD), noting that another chapter covers asthma. The physiological changes which occur in pregnancy, such as the changes in airway physiology, resting ventilation and sleep, are summarised in another chapter. This chapter extends the evidence-based approach and clinical expertise of the recent European Respiratory Society/Thoracic Society of Australia and New Zealand (ERS/TSANZ) taskforce. The papers selected were based on the population (pregnant women with lung disease other than asthma) and the effects of these diseases on risks of pregnancy-associated complications and miscarriages, breastfeeding, nutritional considerations, lung function, long-term maternal outcomes and management considerations during pregnancy. As there are very few randomised control trials in the area, the majority of the literature consists of observational studies (prospective or retrospective), cross-sectional surveys and case series. Other guidelines have also recently been published, which may be helpful to the reader.

Misoprostol for labour induction

Oral and vaginal misoprostol are effective induction methods, but there is a delicate balance between a quicker labour and avoiding side effects. In randomised comparisons with balloon catheters, oral misoprostol resulted in more vaginal births in the first 24 h as well as fewer caesarean sections without an increase in hyperstimulation events. Vaginal misoprostol was most effective when used concurrently with a balloon catheter. In comparison with dinoprostone, oral misoprostol had lower rates of caesarean section and uterine hyperstimulation with foetal heart rate changes, but fewer babies were born vaginally within 24 h. In contrast, vaginal misoprostol resulted in more vaginal births within 24 h, with no significant differences in caesarean section rates. There were no differences in perinatal adverse events with either route. When oral and vaginal misoprostol were compared, vaginal misoprostol resulted in more vaginal births in the first 24 h, but with more maternal and neonatal complications.

ERS/TSANZ Task Force Statement on the management of reproduction and pregnancy in women with airways diseases

This European Respiratory Society/Thoracic Society of Australia and New Zealand statement outlines a review of the literature and expert opinion concerning the management of reproduction and pregnancy in women with airways diseases: asthma, cystic fibrosis (CF) and non-CF bronchiectasis. Many women with these diseases are now living into reproductive age, with some developing moderate-to-severe impairment of lung function in early adulthood. The statement covers aspects of fertility, management during pregnancy, effects of drugs, issues during delivery and the post-partum period, and patients' views about family planning, pregnancy and parenthood. The statement summarises current knowledge and proposes topics for future research, but does not make specific clinical recommendations.

Effects of Prostaglandin E1 on Patients Undergoing Major Gastrointestinal Surgery

OBJECTIVE

The aim of this study was to investigate the clinical effects of prostaglandin E1 (PGE1) in patients who underwent surgery for gastrointestinal (GI) trauma, perforation, or obstruction.

BACKGROUND

PGE1 is thought to enhance intestinal blood supply and reduce GI complications during the postoperative period.

METHODS

The medical records of 889 patients undergoing major GI surgery were reviewed retrospectively. Propensity score matching was performed to adjust for any baseline differences. Clinical outcomes, including early GI function recovery, postoperative complications, and length of hospital stay, were evaluated in all patients. In 278 paired patients, selected nutritional, immunologic, and inflammatory variables were compared based on PGE1 administration.

RESULTS

After propensity score 1:1 matching, the baseline characteristics were similar for both groups. PGE1 was associated with prompt postoperative GI function recovery, including first bowel movement [2.6 ± 0.9 vs 3.1 ± 1.0 days after surgery in patients with and without PGE1 treatment, risk ratio 0.51, 95% confidence interval (CI) 0.41-0.65, P < 0.001] and first feeding within postoperative day 3 [179 (64.39%) vs 152 (54.68%); risk ratio 0.61, 95% CI 0.42-0.90, P = 0.012]. A lower overall postoperative complication rate, including infectious complications [45 (16.2%) vs 68 (24.5%); odds ratio 0.60, 95% CI 0.39-0.91, P = 0.010] and major complications [23 (8.3%) vs 48 (17.3%); odds ratio 0.43, 95% CI 0.26-0.73, P = 0.001], was noted in patients with PGE1 treatment than in patients without PGE1 treatment. Furthermore, the immunologic and inflammatory variable C-reactive protein on postoperative day 3 was reduced by PGE1 treatment (52.5 ± 36.4 vs 89.6 ± 42.4 mg/L; P = 0.037, t test).

CONCLUSIONS

PGE1 is associated with beneficial clinical effects, such as prompt postoperative GI function recovery and reduced overall postoperative complications after emergency GI surgery, which may be attributed to a reduced inflammatory response.
