September 29, 2021

Residency Updates with Dr Jeong + Faculty

  • “A person is smart, people are dumb” -Tommy Lee Jones, Men In Black
  • Department getting busy, thanks for working hard
  • You are responsible for your own education and your own patients
  • Go to every resus, but don’t stay so long that it’s a detriment to your own team — find a balance
  • Your plate should always be full, always be a little bit uncomfortable, always push yourself, write down things and look them up later when hangin’ at a coffee shop
  • Be consistent — work hard with every attending

Dr. Kindschuh updates

  • About half of radiology staff absent due to vaccination mandate
  • Sepsis: Under national benchmark for compliance with 3-hour bundle (below 36%) ☹️
  • Keep ordering radiology studies as you were doing previously
  • Don’t call CT tech unless its critical (time for red zone pts expected to be <90m to get scanned)
  • Don’t do imaging as courtesy to IM team, unless it is not emergently indicated
  • Administered Tenecteplase 6 times in month within the 30 minutes target
    • Studies show outcomes are better if administered at <45 minutes
    • How to order: type in “tenec” → facility list → order set

Eugene – Troubleshooting the Complicated Central Line

Resident Lecture: Rob – Obesity

  • BMI = weight (kg) ÷ height (m) 
  • Super obese (actual ICD 10) is BMI > 50
  • Pulmonary changes in obesity:
    • Restrictive physiologic pattern 2/2 reduction in chest wall compromise
      • —> reduces lung volumes and increased airway resistance
      • Fibrosis from chronic airway changes
    • Respiratory muscles have increased workload and oxygen consumption
      • Intrapulmonary shunting
      • V/Q mismatch
    • Shorter safe apnea time → decreased respiratory reserve
  • Circulatory changes
    • Hyperdynamic circulation – increased intravascular volume
    • LVH
    • LV diastolic dysfunction
    • RV dysfunction
    • ⇧ pulmonary HTN
    • ⇧ systemic pressure
  • ECG alterations in obese patient: 
    • Low voltage
    • LVH
    • ⇧ QT (rarely >500ms due to obesity alone)
    • Pulmonary / R sided strain due to ongoing restrictive airway changes
  • Hematologic changes
    • Prothrombotic (inc blood viscosity)
    • ⇧ fibrinogen
    • ⇧antithrombin 3
    • ⇧ plasmin activator inhibitor levels
    • ⇩ fibrinolysis
  • GI
    • Inc risk of aspiration
    • Increased intra-ABD pressure @ baseline
  • Vital signs
    • Automated BP cuff measures MAP (monitor then extrapolates to get SBP/DBP) 
    • BP cuff can overestimate BP (too small)
    • Borderline BP could represent a shock state in an obese adult
    • Consider placing an early arterial line to obtain and trend bp
    • Shock index can be helpful; SI = HR/SBP
  • Intubation 
    • Setup is MORE IMPORTANT – See below for BIGRAMP
    • Rizzo Tips Korner: Use PEEP VALVE when giving BVM breaths (mask or ETT)
  • RSI drugs – which use TBW vs IBW
    •  
  • Dr. Jeong’s Corner:

Denise CCU/EKG lecture #1 – Post Cardiac Arrest Care

  • Post Cardiac Arrest Syndrome (Post Resuscitation Syndrome)
    • Ischemic reperfusion injury in multiple organ systems
    • Hypoperfusion → pan-organ ischemia → increased metabolic demand
    • Lazarus Phenomenon
      • Spontaneous ROSC following termination of resuscitative efforts – could be in resus room, hallway, body bag, morgue, Ivan’s basement, etc (hours up to a day or two later)
      • Lazarus syndrome – Wikipedia
  • Post-cardiac arrest myocardial dysfunction: 
    • Initially hyperkinetic (catecholamines) then global hypokinesis – 72 hours
    • Systemic ischemia/reperfusion: similar to septic shock
  • Cardiac arrest causes: H’s and T’s (from Osmosis)
  • Hypothermia vs normothermia after cardiac arrest
  • Prognosis
    • Neuroprognostication after Cardiac Arrest (PulmCrit / IBCC)
    • Brain stem reflexes (pupillary, corneal, best motor response at 72 hours)
    • Presence of myoclonic status epilepticus
    • NSE: neuron-specific enolase > 33 mcg.L at 1-3 days
    • EEG/SSEP
    • Apnea test
    • CT/MRI

Dr Seeram – DKA/HHS lecture

  • DM1: Autoimmune/idiopathic destruction of beta cells, so no insulin
  • DM2: Insulin deficiency and/increased resistance
  • DKA/HHS: Similar disease processes – Both can occur in type 1 and type 2 DM 
    • DKA (PulmCrit / IBCC Chapter: DKA), (Deranged Phys: Diabetic ketoacidosis)
      • Typically T1DM
      • Tends to be lower blood sugar (≦250) 
      • More common in younger (<65)
      • Fluid deficit ~6L
      • Usually faster onset (hours to days) → insulin deficiency → ketogenesis → dehydration
      • YES ketoacidosis, not usually hyperosmolar
      • Sx:N/V, ab pain, dehydrated (fluid deficit ~6L), tachypnea, less likely to have a fever
  • HHS (PulmCrit / IBCC Chapter: HHS) (Deranged Phys: Hyperosmolar non ketotic hyperglycaemic coma (HONK))
    • Typically T2DM
    • Tends to be higher blood sugar (500+)
    • More common in older (>65)
    • Fluid deficit 8-10L
    • Usually slower onset (days to weeks) → Insulin presence prevents significant ketogenesis → Severely elevated FSBS (case reports of up to 2400mg/dL) → PROFOUND dehydration
    • NO ketoacidosis, YES hyperosmolarity
    • Sx: Neuro Sx, AMS, confusion, stupor, lethargy, seizures, neuro deficits possible, profound dehydration (~8-10L), less likely to mount a fever
  • Lab Findings in DKA/HHS
    • Pseudo-hyponatremia (dilution of serum sodium with Glucose)
      • TLDR: for every ↑100 glucose → ↑1.6 sodium
    • Hyperkalemia
      • Serum K is normal or elevated
      • Total body K deficient
  • Labs in DKA/HHS
  • HHS TREATMENT
    • VERY similar to DKA treatment
    • NOT chasing ketosis
    • MUCH SLOWER → Took the patient days-weeks to get there, need to drop osmolality slowly to avoid worsening cerebral edema
    • End goal: Normalize serum OSM & improved mental status
  • Dr. Jeong’s Corner: Bicarb indications?
    • Generally, no
    • If huge amount of diuresis/diarrhea, YES cuz losing bicarb
    • Indicated with pH very low (pH <7.1)
    • Considerations for using Bicarb in DKA: Dominating the Acidosis in DKA (PulmCrit)
  • Cerebral edema
    • More common in children
    • High mortality (20%)
    • Tx: Hypertonic saline, mannitol

Dr Rizzo – Everything you ever wanted to learn about catching a SEIZURE 

(DELAYED DUE TO ACUTE-ON-CHRONIC TIME MANAGEMENT DIFFICULTIES)

Resources for seizure discussion:

Notes from Dr. Rizzo:

  • Why talking about managing seizures is important:
    • The longer the seizure continues, the more refractory it becomes to therapy.  The duration of status epilepticus which may cause permanent brain damage is unknown, with experts currently suggesting thirty minutes
    • Aside from the brain, persistent status epilepticus may cause aspiration, hyperkalemia, rhabdomyolysis, hyperthermia, myocardial infarction, and arrhythmia.
  • Definitions
    • Provoked (7 days from event?) vs unprovoked seizures
  • History
    • Questions that can help guide your ED management decisions:
      • Is the patient back to his baseline neurological status? (get collateral info)
      • Is this a first time seizure?
      • Be aware that 50% of “first time seizures” have had prior events (multiple seizures in past consider starting meds)
      • Consider Syncope!
      • Is the seizure provoked or unprovoked?
  • Differential diagnosis
    • Vitals
    • Tox(meds/withdrawal)
    • Addiction
    • Infectious
    • Neuro
    • Metabolic (hyponatremia = 2amps of HCO3- > hypertonic)
    • Cardio
  • Workup
    • FS
    • EKG
    • CT
    • EEG
    • LP
    • MRI
  • Disposition
    • first time seizure + back to baseline → no need for starting AED
  • Status Epilepticus
  • What else can be done?
    • The combination of ketamine and propofol should theoretically provide synergistic anti-epileptic activity.  
      • Propofol stimulates the GABA receptors (the main inhibitory neurotransmitter in the brain)
      • Ketamine inhibits NMDA receptors (a major excitatory neurotransmitter).  
      • The combination of these two effects causes a profound decrease in CNS activity.  Ketamine combined with propofol (“ketofol”) was effective in published series of patients with super-refractory status epilepticus
  • Intubation
    • Some consider it a failure
    •  Others consider it an important part of care that minimizes additional complications
      • Early intubation with PROPER medications while intubated + paralysis concerns
