It is used in Caesarean sections performed at full dilatation. The Fetal Pillow is designed to atraumatically elevate the fetal head out of the pelvis before a caesarean section begins, making the delivery safer, easier and less traumatic. It comprises of a base plate, which is placed posteriorly in the vagina between the fetal head and the vaginal wall. It is then slowly inflated with 180mls of water via a thin tube, which aims to elevate the fetal head. It is removed at the end of the caesarean section.\n\nSome evidence for the Fetal Pillow suggests it can reduce maternal and fetal complications from FDCS by enabling elevation of a deeply engaged head, with some studies demonstrating a reduction in uterine incision extensions, lower estimated blood lossand fewer neonatal intensinve care (NICU)admissions. However evidence is conflicting and newer randomised control trials suggest no difference in outcome when using the device.",[9],null,{"type":21,"name":15,"description":26,"armGroupLabels":27,"otherNames":24},"The Tydeman Tube is a UKCA\u002FCE marked single use sterile device designed to aid delivery of an impacted fetal head at caesarean section. It consists of a semi-rigid wide bore silicone tube and flexible silicone cup.The tube is inserted into the vagina before or during caesarean section where an impacted fetal head is anticipated or encountered. It can be used from 7-10cm dilated. The cup fits against the baby's head. The tube is held by the assistant and used to elevate the head by pushing upwards. This disimpacts the head from the pelvis and brings it towards the surgeon's hand to enable delivery. The cup dissipates the force applied evenly over a wide area of the head which is intended to prevent fetal trauma. Once the surgeon has gained access below the head, the wide bore tube and design of the cup allows air to enter below the head during delivery to limit suction effect. Once the baby is delivered the Tydeman Tube is removed from the vagina.",[15],[29],{"name":30,"affiliation":31,"role":32},"Andrew Shennan, MD","King's College London \u002F Guy's and St Thomas'","PRINCIPAL_INVESTIGATOR",[34,39],{"name":35,"role":36,"phone":37,"phoneExt":24,"email":38},"Laura van der Krogt, MBBS","CONTACT","+4420 7836 5454.","laura.c.van_der_krogt@kcl.ac.uk",{"name":30,"role":36,"phone":24,"phoneExt":24,"email":40},"andrew.shennan@kcl.ac.uk",{"type":42,"investigatorFullName":24,"investigatorTitle":24,"investigatorAffiliation":24,"oldNameTitle":24,"oldOrganization":24},"SPONSOR",[44],{"name":45,"class":6},"King's College London","100621603","lifting-the-impacted-fetal-head-the-fetal-pillow-and-tydeman-tube-trial-100621603",false,"NCT07372768","Lifting the Impacted Fetal Head; the Fetal Pillow and Tydeman Tube Trial","LIFT","Inclusion Criteria:\n\n* Undergoing caesarean section at full dilataion for fetal pillow arm, or caesarean section at 7 or more centimetres dilated for the tydeman tube arm\n* Singleton pregnancy\n* Cephalic presentation\n\nExclusion Criteria:\n\n* Allergy to silicone rubber\n* Major congenital abnormalities\n* Major anomaly of the fetal head (i.e. large encephalocele)\n* Intrauterine death\n* Suspected chorioamnionitis\n* Active genital infection inc.
