Diet and exercise can reduce the risk of developing diabetes during pregnancy
Diet and exercise are effective ways of preventing the development of diabetes during pregnancy, known as gestational diabetes.
Gestational diabetes is becoming more common and is associated with poorer outcomes for mother and baby. Diet, physical activity and weight are modifiable risk factors, but trials published to date have shown inconsistent results.
This systematic review pooled 47 trials and found that any form of lifestyle intervention reduced the risk of gestational diabetes by 23%, ...
Intravenous oxytocin reduces severe bleeding after vaginal delivery
Routine oxytocin injected directly into the bloodstream, rather than into the muscle, after birth results in fewer people suffering severe bleeding (postpartum haemorrhage).
The overall rate of postpartum haemorrhage (PPH) or side effects was similar between the groups, but the intravenous group had fewer severe haemorrhages, needed fewer blood transfusions and fewer admissions to high dependency care. Intramuscular route oxytocin is currently recommended in the UK, partly due to concerns about...
MRI scan does not help to find the cause of pelvic pain in women
MRI scans are not sufficiently accurate to find the cause of chronic pelvic pain in women and should not replace laparoscopy (keyhole surgery), which can be used for diagnosis and often treatment. MRI only correctly ruled out a gynaecological condition in half of women judged to have no obvious cause and missed half of women who did have a treatable gynaecological condition.
Pinpointing the origin of chronic pelvic pain is often difficult due to the number of possible causes. If initial tests a...
Better pain relief for women in labour
Women in labour, who had the short acting strong painkiller remifentanil, rather than pethidine, had less need for further pain relief. Only 19% of women given remifentanil received a subsequent epidural compared with 41% given pethidine. Remifentanil was given intravenously, using a patient-controlled delivery device, and pethidine given by intramuscular injection.
This NIHR-funded study is the first large trial to compare intravenous remifentanil (administered via a patient-controlled deliver...
No benefit from monitoring antiepileptic drug levels in pregnancy
Regular monitoring of antiepileptic drug levels in pregnant women with epilepsy does not improve seizure control compared with clinical features-based monitoring. This NIHR-funded study was conducted across 50 UK hospitals and is the largest randomised trial in pregnant women with epilepsy.
Just over 260 pregnant women with unstable antiepileptic drug levels were assigned to ongoing monthly blood checks or clinical features monitoring. There were no differences in seizures or other pregnancy ou...
Women rate quality and safety of birth experience as important
Most healthy women would like a natural birth if possible, but acknowledge the unpredictability and risks of childbirth. They also appreciate the supportive care environment where healthcare providers are competent, kind and respectful to them, their partners and their baby.
In a large review of studies with over 1,800 women’s views on what matters in childbirth, having a healthy baby was important. Avoiding unnecessary medical intervention and retaining a sense of control over their birt...
Inducing labour at or after 41 weeks reduces risks to infants
Inducing labour after the due date slightly lowers the risk of stillbirth or infant death soon after birth compared with watchful waiting. But the overall risk is very low. Induced deliveries may reduce admissions to the neonatal intensive care unit.
Pregnant women having induced labour are less likely to have a caesarean section than those who wait for labour to begin naturally. They may have a slightly higher chance of needing an assisted vaginal birth (for example, using forceps or vacuum ex...
Outpatient video consultations are feasible but challenging for the NHS
Video consultations may be a useful substitute for face-to-face consultations for some hospital outpatient appointments. This NIHR funded study provided insights into the conditions which made them better. When these practical and clinical conditions are met, video consultations can be safe and effective and are liked by staff and patients. But there are challenges in embedding new technology in routine practice, and these challenges may have been under-estimated.
This high-quality implementati...
Balance of long-term benefits and risks of caesarean delivery explained
Caesarean delivery has immediate known benefits and risks for those women who need help in childbirth. This review measures the long-term outcomes for the mothers’ health, the links to a higher risk of childhood illness and the chance of problems with future pregnancies.
The large review of 80 studies from high-income countries used data from nearly 30 million women and compared caesarean section with vaginal delivery. Caesarean delivery was associated with a lower risk of urinary inconti...
Cell salvage during caesarean section doesn’t reduce blood transfusions
In a large UK trial, cell salvage for women at risk of blood loss during caesarean did not reduce the need for donor blood transfusion, though few needed transfusion (2.5% compared with 3.5% among controls).
More babies are being born by caesarean section and if blood loss is excessive, transfusions may be required, probably by about one in 20 women. Collecting the mother’s own lost blood during the procedure, filtering and returning it to her (cell salvage) is a potential alternative tha...
