Action Planned
The National Ambulance Sector will require the use of either a digital ETC02 monitoring device or full waveform capnography for every intubation with immediate effect. Waveform capnography will be considered the gold standard and the sector is committed to having this in place on every responding vehicle crewed by a paramedic by July 2017. (AI summary)

Dear Mrs Connor,

Inquest reference the death of Sally Perrons Regulation 28 Report- Action to prevent Future Deaths

Thank you for granting us an extension to Sept 1st to respond in full to the concerns you raised following the tragic death of Sally Perrons. I am pleased to advise that I am now in a position to appraise you of the actions that the National Ambulance Sector has agreed to take in response to those concerns.

As you know our work has involved liaising with and canvassing each of the ten English Ambulance Trusts together with the Welsh Ambulance Service. This work has been facilitated by AACE but led by the National Medical Directors Group (NASMED) chaired by

In order to respond to your concerns we undertook a comprehensive survey of the current position of ambulance trusts in relation to intubation and capnography. The questionnaire was prepared and sent to Medical Directors and Lead Paramedics of Ambulance Services in England and Wales. It was also sent to the devolved administrations of Scotland, Northern Ireland and Republic of Ireland and replies were received from them to give a fuller overview of current practice.

The results of this survey established that there is variation in the training and re-assessment of paramedics in the skill and practice of intubation. It found differences and recognised issues around monitoring intubation practice and variation and availability of devices for end tidal carbon dioxide monitoring.

The results of the survey were used to discuss your concerns more comprehensively in the National Ambulance Service Medical Directors Group and agree on a number of actions in response to your concerns which are detailed below.

Your concern:

Point 1: The level of training associated with paramedic intubation – both initial training and subsequent refresher training, particularly given how infrequently most paramedics are called upon to intubate.

Our actions:

 Development  of  a  national  recognised  teaching  standard  for  the  stepwise  airway  management and ventilation.   This will include airway positioning, simple adjuncts and advanced techniques which include supraglottic devices and paramedic intubation. This standard will describe how a paramedic will be initially trained and deemed competent to practice the skill of intubation. This action to be completed by July 2015.

 Development within all services of a common individual paramedic skills log, which  will record airway manoeuvres, use of supraglottic airway devices and intubations as a  minimum.  This could be further developed to include a log of cardiac arrest management, major trauma care and use of other advanced interventions such as intraosseous needle placement and chest decompression. This action to be completed by July 2015.

 Annual  re‐assessment  of  the  individual  paramedic’s  advanced  airway  skills  will  be  based on the airway log, taking into account the number of times advanced airway  skills such as intubation were performed and a review of any problems encountered.  Authority to continue intubation will also be part of the assessment based on whether  any airway management problems have arisen.  This action to be completed by July 2016.

Your concerns:

Point 2: Whether use of waveform end-tidal carbon dioxide monitors is now mandatory.

Point 3: Availability of these devices to staff, and training on how to use and interpret them.

Our actions:

 Confirmation of endotracheal tube placement will now include detection of EtCO2 This  will be mandatory for every intubation with immediate effect and initially will require  the  use  of  either  a  digital  ETC02  monitoring  device  or  the  use  of  full  waveform  capnography. Paramedics will not be allowed to intubate patients where this equipment  is not available to them and will need to manage the airway using alternative airway  adjuncts.   This action to be completed with immediate effect.

 The use of waveform capnography will be considered the gold standard but given that it  will take up to three years time to procure this expensive equipment and train staff in its  use this objective will take longer to achieve. We are however committed to having all  this in place on every responding vehicle crewed by a paramedic as soon as is practically  possible.  This action to be completed by July 2017.

Your concern:

Point 4: In the absence of radical changes, in particular in relation to initial and refresher training, ambulance services should consider whether paramedics should be permitted to intubate patients at all.

 Each individual service will consider whether they continue in the future to teach intubation as a core skill or whether to restrict it to specialised and advanced paramedics. The survey did establish that two ambulance services have already decided that new graduate paramedics will not be practicing intubation in their Trusts.

I hope that you will agree that we have dealt comprehensively with the concerns that you have raised. It has required a great deal of co-ordination between ambulance trusts who have shown themselves to be absolutely committed to learning from this tragic event and doing everything within our power to prevent it happening again in the future. In addition AACE and NASMED will keep progress against these recommendations under regular review and take appropriate action as required to ensure they stay on track.

Investigation and Inquest
On 6 March 2013 I commenced an investigation into the death of Sally Perrons, DoB 26 February 1986. The investigation concluded at the end of the inquest on 27 March 2014.The conclusion of the inquest was a narrative conclusion as follows :

The cause of Sally Perrons’ collapse on 22 January 2013 was natural. However, her death was contributed to by an unrecognised oesophageal intubation. East Midlands Ambulance Service had not introduced national guidelines published in 2010 regarding the use of end tidal carbon dioxide monitoring devices. Had such a device been mandated and used, the oesophageal intubation would have been recognised very quickly after it took place.

The cause of death was :

1a Pneumonia 1b Global hypoxic ischaemia of the brain 1c Cardiac arrest with oesophageal intubation following a non-structural arrthymogenic event.
Circumstances of the Death
Sally Perrons worked as a call taker for East Midlands Ambulance. She attended work shortly after 0700 hrs on 22 January 2013. Her father, , also worked there, and was present that day. At 0739 hrs, she left her work station and went to the toilet. Her colleague found her collapsed in the toilet shortly after 0745hrs. She was quickly noted to be in cardiac arrest, CPR was given and an ambulance was called.

An FRV and ambulance crew arrived at 0755 hrs, and commenced Advanced Life Support protocols. Endotracheal intubation was undertaken by a paramedic,

, at 0800hrs. No other method of maintaining her airway was attempted before intubating. We heard evidence that both and his technician colleague believed they saw and heard reassuring signs – ie that the ET tube was in the trachea, and not in the oesophagus. End tidal carbon dioxide monitoring was not carried out. A second paramedic checked Ms Perrons after she had been moved to the ambulance. He too gave evidence that he believed he saw and heard signs of correct placement.

Shortly after arrival at the Emergency Department of the Queen’s Medical Centre in Nottingham, at 0824 hrs, doctors treating Sally realised that the ET tube was in the oesophagus. This was removed and replaced. She was admitted to the ICU, but died the following day. We heard evidence regarding the extent of training to intubate. The key points were :

1. He had been signed off as competent to intubate in early 2009, after carrying out 25 whilst supervised in an acute hospital setting. He described the difficulty in getting this training, and the reluctance, as he described it, of hospital anaesthetists to assist with it.
2. Before Sally’s collapse, he had personally been involved in 14 intubations of patients, 7 of which were recorded as successful.
3. He had received no refresher training and not been required to carry out practice of intubation technique of any sort since being signed off as competent.

We also heard that it was not until December 2013 that EMAS made use of end tidal CO2 monitors mandatory. We heard in evidence that, after publication of JRCALC Guidelines in this respect in 2010, EMAS produced a draft SOP (dated 19 May 2011).

This SOP states (inter alia) that “intubation is a technique that requires training, experience and regular updating to maintain competence and should increasingly be considered a secondary option following failure of a supra-glottic airway.”

The SOP also sets out that end-tidal carbon dioxide monitoring should be used.

The evidence I heard was that this draft SOP went to the CCG, but was never distributed to frontline staff.

We also heard evidence of a complete lack of consistency in the distribution / dissemination of new SOPs, guidelines or bulletins to frontline staff, and no method of ensuring staff had read or were even aware of new guidance.

I made several findings of fact in this case :

1. Sally Perrons’ oesophagus was accidentally intubated by paramedics at 0800hrs on 22 January 2013.
2. This was not recognised until she arrived in hospital.
3. EMAS failed to adopt and disseminate national guidelines regarding paramedic intubation and use of end tidal carbon dioxide monitoring devices, for some 3 years after the national guidelines were published.
4. After was deemed competent to intubate, he then received no refresher training before these events, 4 years later.

I was assisted at this inquest by an independent expert,

Medical Director of South Central Ambulance Service (Hampshire Division), clinical lead for Hampshire & Isle Of Wight Air Ambulance, and Consultant in Anaesthesia and Critical Care at Southampton University Hospital. , you may be aware, is also lead author for the JRCALC resuscitation guidelines, and chaired a recent review on paramedic airway management. was clear that many of the issues identified at this inquest are not restricted to EMAS, but apply to ambulance services across England and Wales.

He also gave evidence that waveform capnography is far more reliable than paper detectors.
