    Podcast 1008: Acupuncture for Low Back Pain in Older Adults

    Contributor: Aaron Lessen, MD Educational Pearls:  Back pain is a common presenting complaint in the emergency department. Challenges arise when tailoring care to elderly populations using standard medical therapy: Muscle relaxants carry the risk of CNS depression or anticholinergic effects such as urinary retention and confusion. Pain medications such as opiates have side effects including constipation, respiratory depression, and hypotension. NSAIDs carry a risk of GI bleeding and worsening kidney function with chronic use. A randomized clinical trial assessing the effects of acupuncture on low back pain took 800 adults aged 65 and older with chronic low back pain and placed them into one of three treatment arms: Usual medical care Standard acupuncture consisting of 8–15 treatment sessions over 12 weeks, plus usual medical care Standard acupuncture consisting of 8–15 treatment sessions over 12 weeks, plus 4-6 maintenance sessions during the next 12 weeks, plus usual medical care Using the Roland-Morris Disability Questionnaire (RMDQ) score, they assessed disability at 6 months and 12 months. The study found that those who had undergone treatment with acupuncture had significantly greater improvements in disability related to low back pain compared to the group that was only treated with usual medical care. Acupuncture is not used in the ER, but could represent a relatively safe adjunctive therapy for patients who are not responding to standard medical therapy alone.   References:  American College of Surgeons Committee on Trauma.

    Podcast 1007: Caffeine Pharmacology

    Contributor: Travis Barlock, MD Educational Pearls:   Caffeine Geography and Types: Caffeine is found throughout the world and has evolved independently in various plants that are not evolutionarily related through direct lineage, but rather demonstrate convergent evolution (i.e. different species evolve the same traits).  These plants use caffeine as an insecticide.  Examples of caffeine sources include coffee, tea, yerba-mate, guaraná, cacao, and yaupon holly. Roughly 85% of Americans are estimated to consume caffeine daily.   Caffeine Pharmacology in Humans:  In humans, caffeine is a nonselective competitive antagonist (blocker) of adenosine receptors (A1 and A2A).  During waking hours, neuronal metabolic activity consumes ATP, and a byproduct of ATP hydrolysis is created: adenosine.  Adenosine proceeds to build a "sleep pressure".  Acting on A1 and A2A adenosine receptors to induce sleep (on A1, it suppresses neuronal "wakefulness" and on A2A it is believed to be an inducer of sleep).  Caffeine, by blocking those receptors, blunts sleep induction and feelings of being tired.  Caffeine has a half-life of around 6 hours, and a quarter life of approximately 12 hours, which is when the caffeine will off-load and adenosine can once again occupy those receptors, potentially causing a "crash".  Thus, for shift-workers, it is important to time caffeine intake roughly 10 hours before target bed time.  Caffeine exerts other effects on the body.  It is methylxanthine similar to theophylline, which works as a bronchodilator (via phosphodiesterase and adenosine pathways). Caffeine has clinical use to promote bronchodilation in pre-term infants.  Caffeine exerts diuretic effects as well (blocking proximal renal tubule reabsorption).  Recent ingestion of caffeine may blunt therapeutic use of adenosine in patients with SVT.  Key Takeaway? Caffeine exerts a wide variety of effects beyond making us feel more awake. It has cardiovascular, pulmonary, and renal implications in its pharmacodynamics.   References    Benarroch EE.

    Podcast 1006: Cannabinoid Pharmacology

    Contributor: Travis Barlock, MD Educational Pearls:   Endocannabinoid System: THC binds CB1 and CB2 receptors in neurons and immune cells Δ9-Tetrahydrocannabinol (THC) is the main psychoactive compound in cannabis CB1 and CB2 receptors typically bind endogenously-produced 2-arachidonoylglycerol (2-AG) and anandamide (AEA) to regulate pain, stress, and inflammation THC similarly binds CB1 and CB2, leading to the cannabinoid high: euphoria, paranoia, anxiety, analgesia, anti-inflammation, and appetite, among a variety of others Ingestion via edibles, vice inhalation via smoking, leads to chemical modification of Δ9-THC to 11-hydroxy-Δ9-THC, which more easily crosses the blood-brain barrier and binds CB1 with higher affinity, leading to increased psychoactivity   Cannabinoid Hyperemesis Syndrome (CHS): Chronic THC use leading to the classic presentation of persistent nausea and intense, frequent vomiting Chronic activation of CB1 receptors in brain builds a tolerance and dependence on THC, in addition to chronic activation of the capsaicin and vanilloid receptor TRPV1, which binds capsaicin or is activated by heat Treatment by warm showers works due to TRPV1 activation by heat Treated with benzodiazepines, fluids, and gastro-intestinal or central nervous system agents according to patient presentation   Over 200 synthetic cannabinoids have been created (K2, spice, black mamba, mojo, etc), which are more dangerous and can lead to a variety of etiologies   Acetaminophen binds CB1 receptors to reduce inflammatory pain   References Loganathan P, Gajendran M, Goyal H.

    Podcast 1005: Balanced Fluid vs Normal Saline in Pediatric Patients

    Contributor: Aaron Lessen, MD Educational Pearls: There has long been many questions about which IV fluid is best for ED resuscitation Multiple adult studies have shown no clear benefit of balanced fluid vs normal saline A large pediatric randomized clinical trial published in April compared balanced fluid vs normal saline in children with septic shock  The study included about 9,000 patients from 47 emergency departments in five countries Patients with septic shock were randomized to receive either balanced fluid or normal saline The primary outcome was adverse kidney event (death, dialysis, or persistent kidney dysfunction) at 30 days or hospital discharge Results showed no difference in any safety outcomes and no adverse events occurred The key takeaway is that early fluid resuscitation matters more than which crystalloid you choose   References Balamuth F, Weiss SL, Long E, et al.

    Podcast 1004: Sinus Arrest Post TAVR

    Contributor: Taylor Lynch, MD Educational Pearls:    Conduction abnormalities are a common and clinically significant complication in patients who undergo transcatheter aortic valve replacement (TAVR)   Clinical Features The most common abnormalities include high grade AV block and new onset LBBB  Due to the close proximity of the aortic annulus to the AV node and His-Purkinje system More common in males, the elderly, and those with pre-existing conduction disease (RBBB or LBBB) Sinus pauses and sinus arrest are a rare post-TAVR rhythm disturbances Temporary failure of sinus node firing with absent P waves, followed by return of sinus rhythm Sinus Pauses: Typically last Sinus Arrest: Typically last > 3 seconds Not due to direct mechanical injury from the valve, but may occur in patients as a result of pre-existing disease or other external factors: Medications Beta blockers, calcium channel blockers, digoxin Pre-existing damage to the SA node Fibrosis from a previous MI   Treatment If the patient is asymptomatic, provide ongoing surveillance If the patient is symptomatic, treatment should be aimed at the underlying cause: For medication-induced abnormalities, stop the offending medication For acute, unstable bradycardia: Medications: Atropine, Dopamine Infusion, Epinephrine Infusion If cardiology is not immediately available, initiate transcutaneous pacing or insert a temporary transvenous pacemaker Definitive treatment: Pacemaker ~10–15% of patients may develop a bradyarrhythmia post TAVR, with ~8-15% later requiring a pacemaker   Due to the risk of conduction abnormalities post TAVR, many patients are discharged with ambulatory rhythm monitoring such as a ZioPatch or Holter monitor, and may present to the emergency department for evaluation of rhythm disturbances.   References: Kusumoto FM, Schoenfeld MH, Barrett C, et al. 2018 ACC/AHA/HRS guideline on the evaluation and management of patients with bradycardia and cardiac conduction delay.

    Podcast 1003: Nasal Intubation

    Contributor: Alec Coston, MD Educational Pearls: What are nasal intubations and when do we use them? Nasal intubations function similarly to oral intubations with the end goal of passing an endotracheal tube (ETT) through vocal cords and into the trachea to allow for a patent and secure airway, but differ in the main access point for the ETT (nare v.s. mouth). Nasal Intubations are seldom preferred to oral intubations as they carry risk for inducing bleeding from trauma to the nasal passages.  Indications for nasal intubations include: Anatomical abnormalities that may make access through the mouth difficult (i.e. tumors, macroglossia, or rare dental hardware that clenches the jaw shut). Physiological states such as severe angioedema.  Nasal intubations are often done with the patient awake and could be advantageous if the patient is presenting in a severely hypoxic state such that prolonged hypoxia in a traditional RSI protocol may be detrimental. A 2023 retrospective analysis in Germany found that nasal intubations were associated with requiring less sedation than oral intubations and had more spontaneous breathing during hospitalization than oral intubations. How is a nasal intubation performed? Consider the use of an anxiolytic medication such as versed to calm the patient down but not fully sedate them. If there is adequate time without immediate patient compromise, consider glycopyrrolate to reduce airway secretions and dry up the mucous membranes. Consider the use of Afrin or other local vasoconstrictor in target nare to minimize epistaxis.    Use 5% lidocaine ointment and lubricate an NPA and place it into the target nare. This will allow for local anesthesia as well as help to open up the nare slightly more.  Take 5% lidocaine ointment and place it on a tongue depressor and move it around the back of the tongue, allowing it to further anesthetize the oropharynx.  Remove the NPA and atomize/nebulize 4% lidocaine liquid into the nare and into the oropharynx for further anesthesia.  Insert the ETT without the bronchoscope through the nare and allow it to pass about 10 cm until visible in the oropharynx. This allows for a "clean" plastic tunnel to pass the bronchoscope through. Advance both the ETT and bronchoscope, spraying lidocaine through the bronchoscope while advancing to allow for continued numbing.  Pass the ETT through the cords and inflate.  At this point, stronger sedation medications such as ketamine and propofol may be considered but the use of a paralytic like succinylcholine and rocuronium may not be needed to allow the patient to maintain their own negative pressure ventilation.  Which nare is the best to go through? Most patients will have their right nare be the best (away from the septal deviation) according to a meta-analysis by Tan et al.  The right nare was generally associated with less epistaxis and lower intubation times.  However, do not always default to the right nare, and test which nare is more patent by occluding one nare at a time and assessing which one is less resonant  (less resonant = more patent).  Key Takeaway? Nasal intubations are rarer than oral intubations and can be more technically difficult, but may offer advantages in patients with difficult oral airways, but should never be first line.    References: Grensemann J, Gilmour S, Tariparast PA, Petzoldt M, Kluge S.

    Podcast 1002: Elder Agitation

    Contributor: Aaron Lessen, MD Educational Pearls: What are the common causes of agitation in the elderly? Baseline dementia causing a behavioral disturbance Delirium precipitated by an acute medical problem such as a UTI, pneumonia, overdose/side effect of home medications, urinary retention, constipation, pain, hypoxia, electrolyte abnormality, etc. Exacerbation of a primary psychotic condition such as schizophrenia or bipolar disorder. What environmental changes can help reduce agitation? Maintain a quiet, calm, uncluttered environment Dim the lights Ensure the patient has their glasses, hearing aids, and dentures Avoid excessive lines such as foleys Minimize restraints and other forms of immobilization Reassure the patient frequently and have the family check in with the patient What are the best options if medications are required? If the patient is unsafe or non-pharmacologic measures fail, consider a second-generation ("atypical") antipsychotic using the lowest effective dose: Olanzapine Risperidone Quetiapine One special consideration is Dementia with Lewy Bodies, which can be very sensitive to antipsychotics. In this case, Quetiapine is the preferred agent. Avoid when possible: Diphenhydramine and other anticholinergics, which can worsen delirium (including urinary retention and sedation) Benzodiazepines, which may worsen confusion, falls, and respiratory depression Haloperidol, which has a higher risk of extrapyramidal symptoms and QT prolongation than many atypicals References Badwal K, Kiliaki SA, Dugani SB, Pagali SR.
