From our fellow anaesthetist Lars Prag Antonsen comes this eye-opening essay on cognitive processes and how we apply them in high-pressure settings. Very relevant for anaesthetic practice as well as being an enjoyable read. Find the full-text article in the Journal of the Norwegian Medical Association here.
Patients with head- and neck injuries can have challenging airways. We often use videolaryngoscopes or flexible fibrescopes (single use scope) when performing intubation in such patients. Our colleagues in Copenhagen have put together a useful website with videos and other learning resources on that subject. They also arrange an annual two-day airway course with a very extensive workshop. Read more… Continue reading A Few Handy Resources on Airway Management
Brain impact apnoea causes secondary brain injury. The duration of the apnoea reflects the energy in the injury. We often see these patients in our trauma center as they come intubated. CT-scan can reveal structural brain damage or bleeding. In some pastients the CT-scan is “normal”. However, the brain may have suffered hypoxic injuries undetectable with… Continue reading More Brain Impact Apnoea
In a recent article in the Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine by Pakkanen et al, retrospective data from a Finnish prehospital service is presented. They looked at prehospital management of severe TBI (severe head injury with GCS 8 or lower) over a 6-year period, including some 458 patients for analysis. They found a… Continue reading SJTREM: Physician Staffed EMS Associated With Improved Outcomes From TBI
Immediate apnea after acute head trauma is a concept that has received renewed focus lately. BIA/IBA (Brain Impact Apnea or as some call it, Impact Brain Apnea) was described in animal models as far back as 1874 by Koch and Filehne (1). A number of subsequent studies (2-5) have established a clear link between severity of impact and duration of… Continue reading Brain Impact Apnea

Retrospective cohort study by Patanwala and colleagues including 233 head injured patients that required RSI with either rocuronium or suxamethonium. The results reveal that sux was associated with increased mortality in the most severely injured subset, compared with roc. In patients with less severe injury there was no significant difference between the two NMBs. Interesting… Continue reading Roc or Sux in RSI of TBI Patients?
Published in the Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine in 2015. “In this systematic review, we did not identify any studies that investigated the supine position and loss of airway patency in trauma patients. However, we found that the supine position was associated with worse airway patency in patients with reduced levels of consciousness in… Continue reading SJTREM – Review Article on Airway Patency in Supine, Unconscious Patients
“Ideal intubation conditions should be obtained through the use of airway manipulation techniques and appropriate medication choice for rapid sequence intubation in patients who are neurologically injured.” Bucher et al, USA. Journal of Emergency Medicine, 2015 Dec. Read the abstract here.
