Cardiac arrest & resuscitation

Airway and respiratory complications during anaesthesia and associated with peri‐operative cardiac arrest as reported to the 7th National Audit Project of the Royal College of Anaesthetists

AnaesthesiaPublished National audit

Authors' conclusion

Overall, these data, while distinct from the 4th National Audit Project, suggest that airway management is likely to have become safer in the last decade, despite the surgical population having become more challenging for anaesthetists.

Study context

Population
Patients receiving anaesthesia care, including peri-operative cardiac arrest (National Audit Project (NAP7), Royal College of Anaesthetists)

Airway and respiratory complications (activity survey)
Airway complications
421
Respiratory complications
264
Laryngospasm (of airway complications)
157, 37%
Airway failure (of airway complications)
125, 30%
Aspiration (of airway complications)
27, 6%
Emergency front of neck airway

97, 37%
Hyper/hypocapnia (of respiratory complications)
63, 24%

Observational data: associations, not effects.

Further findings

Peri-operative cardiac arrests and deaths due to airway and respiratory complications (881 reports, 358 deaths)

Cardiac arrests from airway/respiratory complications
113 (13%)
Deaths from airway/respiratory complications
32 (9%)
Hypoxaemia the most common primary cause
Survival higher in airway and lower in respiratory cases than other causes of cardiac arrest
Obesity, young children (particularly infants) and out-of-hours care overrepresented

Cardiac arrest from emergency front of neck airway and pulmonary aspiration

Emergency front of neck airway (≈1 in 450,000)
6
Pulmonary aspiration (≈1 in 25,000)
11

Safety

Unrecognised oesophageal intubation

Cases
6
Resulting in cardiac arrest
3
Failure to correctly interpret capnography a recurrent theme
