Desperate Debra, Impacted Fetal Head


Desperate Debra simulator has been designed to facilitate the training and implementation of correct clinical procedures when confronted with impaction of the fetal head - a serious and potentially life threatening event. 


Obstetrics has taken the lead in reducing the number of perinatal and neonatal complications by developing emergency drills for major events such as shoulder dystocia and breech delivery using simulators. Until now, however, no simulator has previously been available for training in dealing with an impacted fetal head.


Features in the Royal College of Obstetricians and Gynaecologists Operative Birth Simulation Training Course (ROBuST) 
80% Experience Rate

Impaction of fetal head at caesarean section is a serious event which is highly difficult to predict. Most senior obstetricians have either encountered or are aware of cases where this has resulted in major morbidity or stillbirth/neonatal death.

In trial groups 80% of surgeons had personal expeirence of difficulty in delivering an impacted head, with a further 70% aware of instances where this has resulted in serious maternal or fetal/neonatal morbities. 


 Improving Training, Reducing Morbidity

Since the 1950�s, various techniques and devices have been described to overcome impaction of the fetal head but none have been adopted into routine practice. The Desperate Debra� simulator will allow for the development of emergency procedures, increase awareness and refine practices for current professionals as well as introducing the issue and ensuring confidence amongst trainees. 


  20,000 Birth Per Year Potential

Many obstetricians first encounter impaction of the fetal head while in training, often at night without immediate access to senior help. There are currently no figures for the exact incidence rate, but with around 200,000 caesarean sections in the UK each year with about 10% at full dilation, there is a potential for it to affect around 20,000 births per year. 


 Increasing Incidences

NICE state that women who fail to progress in the first stage should receive intravenous syntocinon prior to a decision to deliver by caesarean section. This means increasingly women who fail to deliver vaginally are undergoing caesarean section in the late first and second stage of labour, when fetal head impaction is most commonly reported.

Average maternal Body Mass Index (BMI) is also increasing. Pregnant women with high BMIs are more likely to have labour induced or augmented, an increased rate of caesarean section in the late first and second stage of labour and the intrapartum complications with impaction of the fetal head.




The following training skills are possible: 

  • Vaginal examination in advanced labour
  • Identification of fetal head position with palpable fontanelles, variable degrees of flexion and asynclitism
  • General introduction to caesarean section and fetal head delivery
  • Successful delivery of an impacted fetal head at caesarean section with adjustable degrees of difficulty
  • Compatible with inflatable pillow type delivery assistance devices and push from below delivery methods




The Desperate Debra� simulator is highly realistic featuring a pregnant abdomen with pre-cut caeserean incision, uterus and fetal head of a birthing mother with a unique mechanism to replicate fetal head impaction. 


  • Palpable fontanelles in fetal head
  • Variable degrees of fetal head rotation, flexion and asynclitism
  • Unique mechanism to replicate fetal head impaction with variable degrees of difficulty
  • Simulated pelvic bone cast from life
