There appears to be no difference in the efficacy of both these techniques; however, the McDonald suture is often preferred, as it is technically easier to place.

Cerclage is usually carried out between 12 and 14 weeks gestation. Complications include bleeding, infection, initiation of contractions, pPROM and cervical scarring. Unfortunately, the evidence for or against cerclage is unclear.

The benefits of cerclage are well documented if there is a clear history of cervical incompetence, such as previous preterm births or mid trimester pregnancy losses, and an ultrasound examination documenting short cervical length. In 1993, the Medical Research Council and RCOG carried out a large, multicentre randomized trial where 1292 women with a history of pregnancy loss or cervical trauma where the indications for a stitch were unclear were randomized to either cerclage or watchful waiting [56]. Results of the study showed a reduction in deliveries at less than 33 weeks gestation in those with a history of greater than three mid trimester pregnancy losses.

In a more recent meta-analysis of ultrasound-indicated cerclage [57], the authors found that women with a history of previous preterm birth and documented cervical length of less than 25 mm on transvaginal ultrasound would benefit from cerclage before 24 weeks gestation. At present there is not enough evidence to suggest those women with other risk factors for preterm birth such as previous cone biopsy or multiple pregnancy would benefit. The difficulty comes with those women with ultrasound findings but no clear-cut history.

To et al. [58] screened 47,123 cases at the second trimester scan with no history of incompetence. Women with a cervical length measurement less than 15 mm on ultrasound examination were randomized to either undergo cervical cerclage or be monitored.

Results showed there was no significant difference in the rates of PTB at less than 33 weeks. Therefore there is little evidence to support screening and cerclage in women at low risk. From the current body of evidence available, it appears that cervical cerclage may be indicated in women with a significant history of preterm delivery or mid trimester pregnancy loss with documented short cervical length during the current pregnancy, although, again, evidence of a reduction in perinatal morbidity is lacking.

. Obstetric issues in preterm labour Mode of delivery At present there is visual .net Quick Response Code insufficient evidence to suggest the most appropriate mode of delivery for preterm infants. As with term pregnancies, vaginal delivery is associated with lower maternal morbidity and mortality and is therefore the preferred method unless there are indications for CS.

The type of CS incision is important, as at <26 weeks gestation the lower uterine segment is not formed. However, classical vertical incisions carry greater risks for the mother and have implications for future deliveries. CS is rarely justifiable at <25 weeks gestation given the poor outcome for the fetus.

. Care of the premature neonate There have been pub QR Code JIS X 0510 for .NET lic concerns regarding staffing levels in UK obstetric departments. With premature deliveries it is paramount that there are experienced staff available during the delivery, including paediatricians with appropriate neonatal advanced resuscitation experience.

The Safer Childbirth report describes the importance of teamwork between obstetricians, anaesthetists, paediatricians and midwives to provide optimum care for women with high-risk deliveries[59]. This report also highlights the importance of maintaining good clinical practice by providing regular staff training in managing high-risk deliveries, development of clear clinical guidelines for the multidisciplinary management of preterm delivery, and regular audit of departmental practice. Good communication with the mother is essential when dealing with preterm labour and delivery, especially with very premature babies when the outcome is often poor.

NICE guidelines on intrapartum care recommend women with preterm labour or preterm prelabour rupture of the membranes or a condition requiring elective preterm birth should be managed in a dedicated obstetric unit [60]..
