Podcast 627: Oxygen Like It’s Hot

Contributor: Aaron Lessen, MD Educational Pearls: High flow nasal cannula (HFNC) has become more utilized with COVID pandemic Multiple studies have shown this method improves both oxygenation and ventilation Newer studies have shown the respiratory benefit of HFNC  vs normal oxygen in patients suffering from CHF and those with do not intubate orders who are…

Podcast 593: Topicalization for Awake Intubations

Contributor: Ricky Dhaliwal, MD, JD Educational Pearls: Topical anesthetization can allow for an awake intubation, which substantially decreases chance of loss of airway or respiratory drive because sedatives/paralytics are not necessary Lidocaine treatments like URO-JET (2% lidocaine jelly) can be applied through the nare followed by LMX cream (4% lidocaine) which should be applied to…

Podcast 553: Airway Management in the Hypoxic COVID-19 Patient(Recorded 4/3/20)

Contributor: Dylan Luyten, MD Educational pearls: Clinical management of COVID-19 is rapidly evolving, relying on case reports and clinical experience In just a month, the consensus around management of COVID patients with severe hypoxia has shifted from an early intubation strategy to other, non-invasive means Intubating early can quickly consume ventilator resources, require increased intensive…

Podcast 517: It’s all about the PEEP 

Contributor: Dylan Luyten, MD Educational Pearls: Bag-valve masks (BVM) typically  have a port to connect O2 to. Unfortunately room air becomes entrained in the mask, reducing the FiO2 delivered to the patient. This can be overcome by using a PEEP (positive end-expiratory pressure) valve on the BVM  PEEP valves function by keeping alveoli open in…

Podcast # 487: Hunting for Epiglottitis

Contributor: Michael Hunt, MD Educational Pearls: Due to the efficacy of vaccination, epiglottitis is now more common in adults than children Risk factors include smoking and other immunocompromising co-morbidities, such as diabetes Epiglottitis can present with sore throat and fever, with potential rapid progression to respiratory distress and stridor Diagnosis can include x-ray to look…

Podcast #445: Hunting for the endotracheal tube

Author: Michael Hunt, MD Educational Pearls: Bedside transtracheal ultrasound to confirm proper endotracheal intubation is simple and effective Review of 17 studies showed transtracheal ultrasound was was 98.7% sensitive and 97.1% specific Curvilinear probe may be preferable as it provides a larger field of view Editor’s Note: rather than explain what you’re looking for… just…

Podcast #444: Dyspnea in the intubated patient

Author: Aaron Lessen, MD Educational Pearls: Dyspnea can occur in up to 50% of intubated patients Dyspnea is associated with prolonged mechanical intubation Often goes undiagnosed as these patients have difficulty communicating Expert opinion on reducing sensation of dyspnea Reduce stimulation of respiratory drive like fever and acidosis Give bronchodilators for patients with wheezing Optimize…

Podcast #402: Rapid sequence intubation medications

Educational Pearls: RSI includes induction agent (sedative) and a paralytic Succinylcholine is a depolarizing paralytic of rapid onset and short duration with contraindications in hyperkalemic states and muscular dystrophy Rocuronium and vecuronium are longer acting, non-depolarizing paralytic, more commonly Common induction agents are etomidate and ketamine Ketamine can be particularly beneficial for bronchodilator effects in…

Podcast #401: Foreign Body Aspiration

Author: Gretchen Hinson, MD Educational Pearls: Diagnosis can be difficult and often delayed Asymmetric breath sounds, choking, stridor may be present, but children also present asymptomatically Peak incidence around one to two years of age Hot dogs, nuts, popcorn – round and smooth objects are most commonly aspirated References: Green SS. Ingested and Aspirated Foreign…

Podcast #383: Prehospital Tubes

Author:  Sam Killian, MD Educational Pearls: Two high-quality randomized control trials published in 2018 demonstrated no difference in mortality or neurologic outcomes when using a supraglottic airway compared to endotracheal intubation in out of hospital cardiac arrest These two trials enrolled over a combined 12000 patients Supraglottic airways have a higher success rate than intubations…
