Conditions

Recurrent Miscarriage

Brief summary

There is increasing amount of evidence which suggests that miscarriage is related to a primary endometrial problem. Recent cochrane meta-analysis (March 2015) has proven that endometrial scratch improves live birth in women who underwent IVF. The aim of the study is to find out if scratch of the endometrium prevents recurrent miscarriage.

Detailed description

The Warwick BRU-RH (Biomedical Research Unit- Reproductive Health) hypothesis is that failed pregnancies are the result of failed decidualisation of the endometrium.

Interventions

If patient randomised to intervention arm, will have speculum examination followed by endometrial scratch with a wallace catheter

OTHERTouching the cervix

If patient is randomised to the control arm, she will have speculum examination followed by cleaning of the cervix with a cotton tip dipped in saline

Design outcomes

Primary

MeasureTime frame
Live Birth Rate after 24 weeks of gestationfrom the recruitment of the first patient up to 12 months after the recruitment of last patient. the live birth rate of all the pregnant patients in the study who delivered after 24 weeks will be included in the outcome.

Secondary

MeasureTime frameDescription
Miscarriage until 23+6 weeks of gestationfrom the recruitment of the first patient and up to 12 months after the recruitment of last patient. the outcomes of all the pregnant patients in the study who delivered up to 23+6 weeks will be included in the outcome.
Pregnancy complicationsfrom the recruitment of the first patient and up to 12 months after the recruitment of last patient. The patients who delivered after 24 weeks with a live birth will be included in the outcome and the described outcomes will be measuredSuch as SGA(small for gestational age),PET( Pre-eclamptic toxaemia),Abruption, Placenta Praevia, Placenta accreta and Preterm delivery
Acceptability of the interventionPatient questionnaire will be issued at the time of randomisation. the returned forms up to 4 weeks after randomisation will be analysed and reported. this will be helpful for assessing the patients tolerability of the procedureTo guide future trial set up
