Obstetric airways trainer

Obstetric airways trainer

The project aims to produce a prototype level anatomical training mannequin incorporating physical characteristics which are typical in obstetric patient.

General anaesthesia for obstetric surgery, including caesarean section, is often delivered in emergency situations where some of the specific physiological features relating to an individual patient that might affect oxygenation and airway management can be overlooked. 

Failure to intubate the trachea (insert a tube for ventilation) can have disastrous consequences for both the mother and unborn baby due the resulting lack of oxygen.  It is therefore important that anaesthetists are given appropriate training for this patient group.

However since general anaesthesia in obstetrics is relatively uncommon, training opportunities for anaesthetists are limited. The use of simulation and trainers for anaesthetists and their assistants is important in developing and maintaining their obstetric airway skills.

Current airway management trainers exist mainly for adult males, paediatric and neonatal models, including models for rare conditions. There are no obstetric specific airway management trainers for sale on the current market. 

Many of the physical changes which present themselves throughout pregnancy are not incorporated into the generic adult models and specific procedures in relation to obstetric patient positioning are not achievable.

By incorporating the specific functionality needed, we hope to produce a much more realistic obstetric patient training tool which will support learning in obstetric anaesthesia.

Andy Stanton, lead designer

Working with anaesthetists as representatives of Sheffield Teaching Hospitals, Lab4Living is developing a prototype obstetric airway management training tool which incorporates obstetric related functionality. This functionality includes:

  • Varying degrees of upper respiratory tract swelling depending on length of labour, conditions such as pre-eclampsia and use of oxytocin.
  • Enlarged breasts making insertion of the laryngoscope more difficult.
  • Longer hair and use of hair pieces leading to exaggerated neck flexion and suboptimal patient positioning.
  • The facilitation of a left lateral tilt of the operating table with potential incorrect application and direction of cricoid pressure with resulting vocal cord deformity.
  • Shorter neck with the growing prevalence of obesity in this population.

By incorporating interchangeable functionality to present differing emergence scenarios, the design team aims to produce a more realistic training tool to better inform clinical teams in the area of obstetric anaesthesia.

This project explores opportunity for design beyond the creation products and focuses on how design might help change culture and behaviour within a health care environment to improve the safety of frail older people admitted to hospital. frailsafe was created to explore whether a check and challenge approach could be translated into the complexity of acute medical care and safety of older patients. The project was was supported through the Health Foundation as part of the Breakthrough Series designed to help organizations by creating a structure in which they can easily learn from each other and from recognized experts in topic areas where they want to make improvements.

International studies indicate that approximately 10% of all patients who are admitted to hospital suffer some form of adverse event (AE). An AE can be defined as an unintended harm to a patient resulting in injury, death or a prolonged admission. Older people are more likely to suffer AEs and the consequences of an AE are often more severe in frail, older patients.

12 hospitals were purposively sampled to replicate the proportion of patients in District General / Teaching and Urban / Rural settings around the UK.
Design researchers were involved more than 100 hours across the 12 hospitals shadowing different health professionals, following ward rounds, board rounds, triage meetings, handover discussions and multidisciplinary (MDT) meetings.
In addition three two-day residential learning sessions located away from the immediate local pressures of work were scheduled over the duration of the project. These offered a creative space to collaboratively engage through a series of Design activities that were developed and facilitated by the design researchers.

Staff found their participation in the improvement team as one of the most rewarding aspects of the project and showed spill-over effects in the wards. The project provided a platform and protocols for increased multidisciplinary working and enhanced communication on what constitutes good care for older patients in AMU.

In addition to co-designing with hospital staff a series a videos were co-created with older people to explore the notion of frailty from a personal perspective.

The research highlights the scope for designers to facilitate co-design that can be embedded as a lasting legacy in communities helping them to learn from each other through improved communication and empowering them to create and implement their own new ideas.
