I am NOT an anaesthetist!!!
Intubating In ED • Why it is a danger zone • Role of Checklists • Pre-oxygenation and Apnoeic Oxygenation • Laryngoscopy
ED Patient Airways are Different • They are emergent – Usually for airway +/- breathing failure – Limited history – Limited opportunity to predict difficult airway or difficult laryngoscopy – They are sick… Really sick (ie high metabolic demands)
I have a bad feeling about this one!!! I LOVE it when I have a registrar!! Oh S!!! I knew I should have called in sick today!!
Our training and Skill Level
Our Training and Skill Level Adequate supervision and support Anaesthetics and ICU experience E-learning and simulation training to practice drills Credentialling process and guidelines on who should be allowed to intubate in ED and other critical care environments
Suggested parameters for predicting the difficult airway Long upper incisors and/or prominent overbite Inter-incisor distance <3 finger breaths Mandibular floor distance < 3 finger breaths Thyromental distance < 2 finger breaths Mallampati score > 2 High arched palate Large, thick tongue Short, thick neck Patient unable to touch the chin to the chest
Are they any good? In 2003 ASA Difficult Airway Task force after a review of literature found there was insufficient evidence to recommend any predictive tool, however some of these markers were associated with difficult airways!
So..What Do We Do?
