If you have the urge to order Mag for a patient, follow your intuition. But Mag might be even more important when replacing potassium.

When treating hypoK+, if the patient has an IV or will have one, I just order Mag 2g IV rapid infusion (never need to do it slowly, 20 minutes is great) along with 60meq oral K. If they are below 2.0 K+, I either give 2 K runs or if they need/can tolerate volume, a liter of D51/2NS with 20meqK (K runs which are painful and seem to take forever to get to the bedside). Of note, people with CHF very often Mag depleted from diuretics and other etiology.

If you give the Mag IV and K po a the same time, Mag is hitting them first. Tough ones are when you don’t have an IV, because Mag oxide is trash. Sometimes I still order it. But people with no IV are likely not very sick and probably have K above 3.

Something might happen when K gets below 3. So if below 3, I usually give some IV, some po.

Dr Harmon asked me about this before she graduated, and I went looking for a few papers on it. I did a little lit search and cant find a true RCT of K repletion VS K repletion WITH or AFTER Mag repletion. It would be expensive to do and lots of confounders and no one wants to spend $ on a Mag study because it’s an old, cheap medication. **(Although some press coverage now on a Magnesium L-Threonate [which I take] study that showed cognitive benefit in Alzheimers patients).

In the few relevant papers I found, authors just generally recommend Mag with K. But we should always be careful when doing something that is logical but isn’t proven empirically. Sometimes things that make sense in theory don’t pan out in studies (vitamin C in sepsis).

One study in ICU patients compared those getting lots of Mag vs those getting none, and looked at their K balance. They found an obvious benefit to Mag repletion for K balance. They cite lots of basic science research on the K-Mg interplay.

At the end of the day, most people are Mg deficient and people with low K maybe even more likely Mg deficient. Mag is awesome, no downside, patient might flush or get sleepy. Just watch out in those with renal failure.

• Not so e(FAST)
  • Do not bias yourself against doing an eFAST (especially if intoxicated and concerned for blunt trauma)
  • Novice scanners need around 600mL blood for FAST to be positive
  • Serial FAST can increase the sensitivity of the exam and decrease false negatives by 50%
  • Head injury and mild abdominal pain are associated with false negative FAST (be cautious with your FAST conclusions)

  • Generally for “unstable” patients
  • Specific considerations
    • Trauma -> will need a man scan, intoxicated and difficult exam, open fractures
    • Stroke -> 10-minute goal door to CT time
    • Medical – > hypotension, hypoxia, AMS, seizure, shock
    • Sedations, procedures, cardioversion, etc.

    • Consider am I comfortable waiting several hours for their workup to start resulting?
    • Who to keep (trauma) -> man scan?, trustable exam?, vital sign derangements?, fracture/dislocation needing intervention?, elderly fall on thinner and isolated GSW to the extremities are common rollouts but do a thorough exam first
    • Who to keep (medical) -> hypotension, hypoxia, most respiratory intervention, intubated transfer patients are common rollouts

    • Cannot be injected IV (due to naloxone)
    • Minimal side effects and contraindications (acute liver failure)
    • 2% bioavailability of naloxone when taken sublingually, so does not affect buprenorphine absorption
    • Trying to use opioids after taking suboxone is not particularly effective because buprenorphine is saturating receptors

    • Try to start with 8mg on day one, 16mg (8mg BID) day two, etc.
    • Can start at COWS of 8 (with objective signs) or 12 without
    • Can always start with test dose of 2mg. If they get worse, then likely used opioids more recently than they say or withdrawal is not severe enough. If they get better, then safe for higher dose
    • Precipitated withdrawal -> can either do supportive care or give higher doses of suboxone
• Air Methods
  • Benefits of an air ambulance -> saves time (most benefit when ground time is >1 hr), ability to give blood products, preserves “golden hour” of resuscitation

ENT Lecture with Dr. Vinh

Airway complications: Tracheostomy vs Laryngectomy
-	Tracheostomy: ask three questions
o	Why does patient have tracheostomy?
	Most common is failure to wean from vent > still able to intubate from above
	Anatomic obstruction from tumor, etc. > typically will be difficult to intubate from above
o	How long has trach been present?
	Takes at least 1 week for tract to mature
o	What type of trach is it? Cuffed or uncuffed?

-	Laryngectomy
o	Trachea is directly connected to skin
o	There is no airway from the nose and mouth
  cannot bag over mouth or intubate from above
o	Can use pediatric size BVM over stoma to bag

Complicated airways
-	Ludwig’s Angina – submandibular space infection which causes upper airway obstruction
o	Odontogenic infections account for ~70% of cases
o	Treatment with Unsyn and Vanc + surgical drainage and/or tooth extractions
-	Angioedema
o	Treatment
	Corticosteroids, antihistamines, epinephrine, stop ACE-Is
o	Always perform flexible laryngoscopy – laryngeal edema may be much worse than visible oropharyngeal edema
-	Peritonsillar abscess
o	Management – antibiotics (unasyn or augmentin), +/- steroids, +/- I&D or needle aspiration
o	Can have trismus (usually due to pain)
-	Epiglottitis 
o	Majority of cases caused by staph and strep – empiric antibiotics with Vanc and Unasyn
o	Swelling of the larynx causes disproportionate narrowing of the airway compared to other anatomic sites
-	Head and neck cancer

Securing the airway
-	Supportive measures
o	Treat underlying cause
o	Supplemental O2
o	Racemic epi – useful for laryngeal edema
o	Heliox 
-	Sedation/anesthesia?
o	Anesthesia causes airway obstruction due to loss of muscle tone, suppression of protective arousal responses and decrease in respiratory reserve
-	Make plan for intubation
o	Fiberoptics for oropharyngeal obstruction
o	Cricothyroidotomy for laryngeal obstruction
-	Fiberoptic intubation
o	Transoral vs transnasal
o	Local anesthesia is key if unable to sedate  atomizers and 4% lidocaine
o	Afrin and serial dilation with nasal trumpets

Transfer Center Lecture with Dr. Mallory

o	IV Diamox 500 mg
o	IV mannitol 1-2g/kg over 45 minutes

Ejection Fraction and Cardiac Imaging with Dr. Baker

• Normal EF findings on POCUS – wall thickening and symmetric contraction during systole, anterior leaflet of mitral valve slapping interventricular septum
• Ways to calculate EF using POCUS
• EPSS = End point septal separation
  • Less than 7 mm = normal
  • Greater than 10 mm = reduced EF
• Fractional shortening – measures LV in systole and diastole
• Fractional area change – uses RV volumes in end systole and end diastole to calculate EF
• Simpson Biplane method – US will calculate change in volume of the LV between end diastole and end systole

As mentioned in conference recently, we have years of various studies on the use of Magnesium Sulfate in COPD and asthma. See below a Cochrane review on asthma.

But right after conference, I checked my email to find hot off the press in Annals of EM, a brief review on Mag in COPD.

Take-Home Message

Among patients with an acute exacerbation of chronic obstructive pulmonary disease, intravenous magnesium sulfate may be associated with fewer hospital admissions, reduced hospital length of stay, and improved dyspnea scores.

Here is the Cochrane review on Mag in Asthma. Authors’ conclusions: This review provides evidence that a single infusion of 1.2 g or 2 g IV MgSO4 over 15 to 30 minutes reduces hospital admissions and improves lung function in adults with acute asthma who have not responded sufficiently to oxygen, nebulised short-acting beta2-agonists and IV corticosteroids. Differences in the ways the trials were conducted made it difficult for the review authors to assess whether severity of the exacerbation or additional co-medications altered the treatment effect of IV MgSO4. Limited evidence was found for other measures of benefit and safety.Studies conducted in these populations should clearly define baseline severity parameters and systematically record adverse events. Studies recruiting participants with exacerbations of varying severity should consider subgrouping results on the basis of accepted severity classifications.

Lithuania

-training in Lithuania is 6 years and they graduate with a masters degree with ability to practice in EMS, ED and palliative care

-EMS services only carried out by EMS personnel, not fire or police

-Ambulance types: BLS, ALS, ALS intensive care

-BLS-minor traumas, cardiac arrest if nearest, transport, psychiatric emergencies, minor medical- Can start IV and apply supraglottic airway, no meds

-ALS- Nurse and driver-paramedic- can administer medications, can interpret EKG, supraglottic devices, intubation, procedural sedation, etc.

-ALS ICU- Doctor, nurse, driver-paramedic- US, terminating CPR, invasive and non-invasive ventilation- most critically sick patients

Riot Dispersal Agents and GSW Management

-Tear gas fall under chemical weapons- designed to be an irritant that leaves no lasting damage (not always the case)

-14 cases of death from these agents, but all have been from people getting struck with the cannister (in the US)

-In Israel have had cases of people dying from chemical itself when deployed in poorly ventilated areas

-No long term studies- there are concerns for long term toxicity

-Decontamination- removing from exposure

-Copious water irrigation

-Velocity of the GSW is what determines damage- high velocity causes worse disruption

-Two types of wounds: 1. Penetrating- enters but does not leave body 2. Perforating- enters and leaves body

-ABI for concern vascular injury- <.9 needs angiography, >.9 but less than 1.0 needs obs

-71% of those with arterial injury have concomitant nerve injury

EDH

-Introduction to Dr. Syed Shah

AAEM

-Est. 1993 to advocate for EM as a specialty

-Key Issues: Advocacy, Board Certification, Corporate practice of medicine, EMTALA, Due process

-AAEM has multiple resources and benefits to include scientific conferences, podcasts, help in establishing/finding democratic groups, etc

-When thinking about your finances, replace your “buts” with “ands”- for instance “I’m about to make 300k a year AND I don’t know what to do with it”, rather than saying “…but I don’t know what to do with it”

-Think about other streams of revenue. Examples: selling a product, content creation, renting room/property

-Take inventory of your life. What does your millionaire life look like? What kind of car do you want? House? What do you want to do with your time?

-Estimate the monthly costs of these. It is likely easier for you to “live your millionaire life” than you might think, and setting these goals and visualizing them can help you in determining your pathway to them.

Ortho tips and tricks for closed reductions

-Purpose- to restore length, alignment, rotation

-Helps with patient comfort, protecting cartilage, keep neurovascular structures away from stress, prevent skin/wound complications

-Also trial of non-operative management

-Needs pre-reduction XR

-Recreate the deformity to “unhinge”

-Consider your deforming forces- what structures at risk, what muscles/forces pulling fracture, what will open joint space, etc.

-Tourniquets can get in the way, so try and take down if possible

-Molding- holds your reduction in place, 3 point mold (never mold over bony prominence)

-Purpose of CT is to evaluate joint

-Rare to obtain CT prior to reduction unless there is a block of some kind

-Every time a joint gets dislocated it will need to stressed to assess for stability- this will determine need for operative management

-Unstable hip dislocations need traction pins

-Elbow test flex/extension + varus and valgus stress

-Unstable dislocations get ex-fix EVEN IF NO FRACTURE

-Joint dislocation is emergent in the ortho world

-Shoulder reduction

              -Do not try alone if there is an associated fracture, TSA or rTSA in place

              -Milch maneuver

              -Stability exam

              -Scapular Y XR and axillary views

-Elbow Reduction- typically associated with ligamentous damage

              -Simple- no fracture, complex- fracture

              -Terrible triad injury- LUCL, radial head, coronoid

              -Inline traction, supination, flexion

              -Stress the joint

              -Neurovascular exam

              -Monteggia- Proximal 1/3 ulna + radiocapitellar jt- make sure that radial head is reduced!!

                            -Blocks to reduction- annular ligament, biceps tendon

                           -Stress- especially pronation and supination- need to splint in whichever is more stable

-Hip- posterior wall fracture

              -often associated with acetabular fracture- if it isn’t try not to cause one

              -Captain Morgan reduction, East Baltimore Lift

              -Flexion, adduction, internal rotation (for posterior dislocation)- Stress exam

              -Make sure to get pre-reduction XR

              -When to ask for help- traction pin, peri-prosthetic

-Knee dislocation- often associated with neurovascular injury

              -First steps- physical exam, doppler, ABI’s?, CTA’s? (not super sensitive for intimal flaps)- typically keep these for obs for 24 hours

              -Vascular consult?

-Subtalar Dislocation

              -Difficult reduction- try and call ortho for this

              -Different than the tibiotalar dislocation (standard ankle dislocation

              -Dislocation of the talus and calcaneus

              -need to relax gastrocnemius muscle- flex the knee

              -Plantar flex the ankle

              -Is the talonavicular joint in place after reduction? Can see on post reduction lateral films

-Remember 3- point mold, and do not mold over bony prominence

-When does it not matter

              -certain fractures- humerus, femur shaft/ distal femur, both bone forearm, tibia +/- fibula

              -Just need to get to length

-Up to 25% of SCI occurs after initial insult- extraction, transport, handling, early mobilization

-Spinal tracts:

              -Descending Motor tracts: Lateral corticospinal, ventral corticospinal

              -Ascending sensory tracts: Dorsal columns (fine touch, proprioception, vibration), Lateral spinothalamic (pain, temp), Anterior spinothalamic (course touch, pressure)

-High dose steroids not recommended in spinal cord injury

-Brown-Sequard Syndrome- transverse hemi-section or unilateral compression

              -ipsilateral spastic paresis, loss of proprioception/vibration

              -contralateral pain and temperature loss

-Central Cord syndrome- squeezing of the cord affecting inner portions

              -Quadriparesis worse in upper extremities

              -Cape like distribution

              -Sacral sparing

              -MRI, NES/Spine

-Anterior Cord Syndrome

              -Direct compression or ischemia of anterior 2/3 of spinal cord

                           -disc protrusion, AAA, hyperflexion, emboli

                           -loss of pain and temp

                           -Bowel/bladder dysfunction

                            -Dysautonomia

-Spinal Shock- injury resulting in transient global loss of function w/ temp flaccid paralysis, bowel/bladder dysfunction, anesthesia, loss of reflexes

              -Resolves in days to weeks

-Neurogenic Shock- injury to spinal column resulting in hypotension, bradycardia, and hypothermia

              -occurs in <20% of SCI patients

              -injury level:

                           -Above T1- full sympathetic denervation

                           -T1-L3: partial denervation

              -Management:

                           -Exclude other causes of vital sign abnormalities

                            -MAP goals- first line pressor (MAP goal 85-90)

                           -Levo first line, can add phenylephrine as second line pressor

                           -Atropine, temp probe, bair hugger

Dr. Jacobs- Life after Residency

-Show up 15 minutes (at least) early for your shifts

-Get to know the people you work with and be friendly

-Avoid arguments

-Flow is important- order everything you think you might need (within reason) right out of the gate- will speed things up ultimately

-Ask for help if you need to- case management, colleagues, PT/OT, nurse manager, etc.

-Don’t vent your anger in public- beware of being recorded

-Temper patient expectations- don’t over-promise, do what you can do

-Don’t get locked into a diagnosis and refuse to budge- avoid confirmation bias

-Listen to your nurses, involve them in care- will help with building relationships

-Recognize your feelings- if you need a minute to decompress or vent, do so before your feelings boil over

-Get a lawyer/accountant/financial advisor onboard early in your career so you can maximize your pre-tax deductions, retirement accounts, etc.

Peds: Ortho/ NAT

-Le fort fractures never occur in children less than 2 due to lack of pneumatization of the sinuses

-Children less than 8- susceptible to ligamentous and growth plate C spine fx that are higher up

-Older children lower C spine fractures more common

-Posterior displaced medial clavicle fx needs CT to ensure no compression of mediastinal vessels or trachea

-Salter Harris classification

-Gartland Classification supracondylar fx- type II and III likely to require surgery

-Galeazzi

-Monteggia-

-Toddler’s Fractures- 12-94 months, low energy trauma w/ rotational force

-Subtalar joints have poor blood supply making it prone to osteonecrosis

-Chopart- separates midfoot from hindfoot- important for pronation and supination

-NAT- TEN 4 FACES P

-torso including genitals, ears, neck, frenulum, angle of the mandible, cheek, eyelid, subconjunctival hemorrhage, patterned bruising

-4- any bruising in a child less than 4 months of age

-95.6% sensitive, 87.1% specific for NAT

-Point tenderness over an unfused epiphysis concern for non-displaced salter harris- need splinting and follow up

-Nursemaids elbow- mechanism is being pulled

-Reduced by hyper-pronation or supination/flexion

-pain is usually at wrist

Tactical Medicine

-Swat developed after the Texas tower incident Aug 1, 1966

-1989 to 1990 interest began in involving medical professionals with SWAT

-Officers to learn methods of self rescue and to provide basic medical care

-TCCC- Tactical Combat Casualty Care

-Hot zone- immediate area with perpetrator- shooting back, moving casualty out of hot zone are priority

-Warm zone- potential for hostile threat, not under direct fire- Immediate care can be performed here- tourniquet, Chest seal/decompress, airway

-Cold zone- No significant threat of danger- more definitive care

-They use (S)MARCH- security, massive hemorrhage, airway, circulation, hypothermia

Nailbed Injuries and Arthrocentesis

-Indication for trephination- less than 1-2 days old, 50% or more of nail bed

-Be careful with flammable alcohols and check for acrylic nails as these are also flammable

-Nail bed laceration- digital nerve block, remove nail, repair w/ 5-0 or 6-0 absorbable sutures, replace nail into fold

-Arthrocentesis- suspicion of septic arthritis, crytal arthropathies, unexplained arthritis W/ effusion, eval of jt capsule integrity in trauma, therapeutic relief of pain/ effusion

-Contraindications: No absolute but relative include overlying cellulitis, prosthetics

– >50k WBC, >90% PMN cells indicative of septic joint

Venous thromboembolism

• 90 day overall PE mortality rates were 17% in 1999, 16% in 2018
• Inari FLASH registry 30 day mortality rates for High and intermediate risk PE patients were 0.8%
• Nearly half of submassive 30 day mortality occurs outside of hospital
• Lightning Lectures:

Pelvic Fractures

-3 month mortality 3x higher in trauma patients with pelvic fractures

-Increased concern for bladder/urethra injury

-Sacral fractures -zone 1, 2, 3- 3 is worst prognostically

-APC 1 <2.5 cm pubic symph

-APC 2 >2.5 + anterior ligament

-APC 3 >2.5 + ant+ post

-Vertical sheer

-Pelvic binders: unstable and pelvic injury suspected. Over trochanters.

-Inlet/outlet films, judet AP and lateral decubitus position once stable

-FAST can help determine if needs lap (+ blood) or embolization

Compartment Syndrome

-1-10% of tibial fractures, ant compartment most common

-Normal compartment pressure < 10 mmHg

-<20 mmHg unlikely to cause damage

-CK, UA for myoglobin (rhabdo in 40%)

-Stryker- compartment >30 mmHg in one compartment

– Delta pressure: diastolic – pressure (30 or less is indication for fasciotomy)

-Fasciotomy w/in 6 hrs 100% recovery

-12 hr 66%

Ortho Plain Films

-Most often missed finding is the 2^nd finding

-More views are better

-Axillary view very helpful in glenohumeral joint evaluation

-Posterior shoulder dislocations- hard to see, patient can’t externally rotate (lightbulb sign), lack of crescent sign

-4 views at the elbow

-Monteggia fracture- Proximal ulnar fracture with dislocation of radiocapetallar joint (radial head dislocation)

-Galeazzi fracture- Mid to distal third of ulna with dislocation of distal radioulnar joint

-Maisonneuve- total disruption of interosseous membrane

Strangulation injuries are a tough chief complaint. We have many considerations in evaluating and managing these patients. Top priority is ABCs, and then ruling out other serious injuries in the patient.

We may tend to have too low a threshold for CTA in these patients. But they often end up in court proceedings and one could argue for the more aggressive imaging strategy for this reason. Of note, strangulation in the setting of domestic violence represents a VERY high risk mechanism to predict subsequent fatal injury in intimate partner violence.

I am not offering a clear cut answer on when to CTA and when not to. This should be a decision you make with the patient and your attending, considering patient age, injury severity, etc. But the two resources below can at least provide some context on evidence for imaging.

1. Check out this algorithm, authored by Dr. Bill Smock who was UL EM faculty for years and worked with the LMPD as the police surgeon for years. He writes the forensic medicine chapters in a few textbooks as well.

OBGYN Review with Dr. Platt 

AUB= consider cancer in women over 45 yo F

US imaging of choice for genital tract pathology 

Ovarian cyst > 8cm, solid, multiloculate are worrisome for neoplasm, dermoid cysts, or endometriomas

An ovary > 4 cm in size is the most common US finding associated with torsion 

False labor= uterine contractions that don’t cause cervical changes 

Amniotic fluid changes nitrazine paper dark blue 

Sterile speculum exam, no digital exam if ROM suspected

DED/72 Hr Return Learning highlights with Dr. Royalty

A patient is considered refractory after 3 or more defibrillators, 3 or more doses of epinephrine, AND 300 mg Amiodarone 

What therapies can you try?

-Hold additional epinephrine 

-Administer Esmolol for electrical storm: 500 mcg/kg bolus followed by infusion (50-100 mcg/kg/min)

-Dual-sequential Defibrillation: Place a second set of pads (R upper chest/left lateral and anterior/posterior), deliver 200J simultaneously from both defibrillators

Pediatric Cardiac Disease with Dr.Wadih

Cyanotic lesions: 5 T’s-Tetralogy of Fallot, Transposition, Tricuspid atresia, Truncus arteriosus, TAPVR

Truncus arteriosus: Associated with 22q11 deletion (DiGeorge), Primitive truncus does not divide into PA and aorta, Leads to significant pulmonary over circulation, Ductal independent 

Tetrology of Fallot: Large VSD, RVOT obstruction, RVH, overriding aorta. Tet spells= episodes of cyanosis usually triggered by crying. Treat tet spells by calming, knees to chest, supplemental O2, morphine, IN fentanyl or versed if no IV, IVF to increase preload. If these fail, move to beta blocker propranolol or esmolol, ECMO last resort. Degree of RVOT obstruction determines if lesion is ductal dependent. All require surgery

Total anomalous pulm venous return: Pulm vein do not return to L atrium, degree of illness depends on degree of obstruction of pulm venous return. Ductal independent. Must have ASD to survive 

Transposition of Great arteries: Must have large ASD , VSD, or PDA to survive. Usually presents within hours of birth. If not responding to prostin need a balloon atrial septostomy.

Tricuspid atresia: Absence of tricuspid valve w/ hypolastic RV. Relies on ASD 

L->R shunts: ASD, VSD, PDA, AV canal 

ASD: rarely symptomatic, usually close on their own. Typically close ASD around age 2-5 if becomes larger or persists. “fixed split S2” is a buzzword for ASD on exam 

AV canal (AV septal defect) commonly associated with trisomy 21. Spectrum of severity, all require repair 

VSD: Highly variable. Bigger VSD= more likely to cause heart failure, less likely to hear on exam. Smaller VSD= less likely to cause issues and may close on their own, louder murmur on exam. Over time will lead to increased PVR, increased RV pressure and RVH. May present at 4-8 weeks of life in heart failure, slightly later in trisomy 21

PDA: Machine like murmur at left upper sternal border. Persistence of ductus arteriosus. Ibuprofen used to encourage closure. More common in premature infants 

Ductal dependent lesions (depend on PDA): HLHS, critical aortic stenosis, critical coarctation of aorta, pulm atresia, +/- tet

These NEED PGEs. Prostaglandins cause apnea. Presents with murmur, cyanosis, heart failure on exam. Poor feeding with poor weight gain, sweating with feeds, irritability, tachypnea. W/u with pulse ox: R hand is pre ductal, >3% difference b/t pre and post ductal sats. Need CXR, EKG, Echo. Give prostaglandin .05-.1 mcg/kg/min, watch for apnea. Milrinone typically inotrope of choice due to vasodilation (doesn’t increase SVR). Consider epi for shock 

Coarctation of aorta: As PDA closes- hypoperfused lower extremities, hypertensive upper extremities, associated with turner’s. Present in shock as PDA closes. Coarct located pre-ductal is ductal dependent. Coarct other locations may not present until later in life 

HLHS:Hypoplasia of LV and ascending aorta, mitral valves with ASD and PDA. Cardiogenic shock when PDA closes. Mortality highest in 1^st year of life. Staged repair, first stage is Norwood(BT shunt connects PA and aorta) which is done during the 1^st few weeks of life. IF BT shunt clots they will die. 12% rate of clotting. Post op period is high risk. Listen for a shunt murmur

If you think shunt closed, bolus heparin and start drip. Consider ECMO, likely needs emergent surgery. Increase SVR with pressors (epi first choice), sedate and paralyze to reduce PVR( intubate). Once make it through staged repair survival rate is 90% at 30 years old. Atrial arrythmia is common comorbidity, also liver failure 

Ebstein’s anomaly- associated with maternal lithium use. R atrium enlargement, malformed tricuspid valve 

Eisenmenger syndrome: complications of uncorrected L->R shunt. Can occur in childhood or adulthood depending on the lesion. Cyanosis, syncope, dyspnea, fatigue, chest pain, sudden death. Increased pulm resistance, pulm HTN causes shunt to switch to R->L

Thoracic review with Dr. Baker 

Light’s criteria- if any one of the following is present the fluid is almost always an exudate: pleural fluid/serum protein ratio > 0.5, pleural fluid/serum LDH ratio > 0.6, pleural fluid LDH > 2/3 upper limit for serum LDH 

TB drug side effects: Ethambutol can cause optic neuritis.. starts with E and is eye pathology. Rifampin= orange body fluids. Isoniazid= peripheral neuropathy, seizures, B6

-Spontaneous PTX >20% needs chest tube. Smaller can be observed with oxygen administration 

-To prevent BPD in neonates: within one hour of birth give neonate surfactant, after an hour give caffeine. Risk factors are tobacco use, IUGR, preeclampsia

-Tracheoinonomate artery fistula. Overinflate cuff-> intubate-> remove trach-> digital compression of innominate artery 

-Pertussis buzz words: several weeks, eye sxs, post-tussive emesis 

-Coin position on xray: SAFE= sideways airway, frontal esophagus 

Most common symptom in PE: dyspnea

Most common sign in PE: tachypnea 

Tolerating secretions and toxic= tracheitis

Drooling and toxic= epiglottitis (Hib), thumbprint sign 

Spontaneous and stable Pneumomediastinum: dc with f/u. asthma most common trigger.. Hamman sign, pleuritic pain and neck pain. Usually self-resolving 

-Gram+ cocci in clusters= staph aureus 

-PNA+ bullous myringitis= Strep pneumo Phosgene smells like hay or cut grass 

CURB65: confusion, BUN>19, RR > 30, SBP <90 or DBP < 60, Age > 65

Berylliosis= Aerospace, fluorescent bulbs

Silicosis: glass, sand blasting, miners

Asbestosis: shipyard workers

Siderosis: arc welding (iron)

Most specific US finding for PTX: lung point sign 

Pneumocystis jirovecci: elevated LDH

Give prednisone if PaO2 less than 70 

Fat embolism: IVF and supplemental O2, may see petechial rash

Case Reviews with Dr. Weeman and Dr. McMurray

Meningitis

• Strep Pneumo most common pathogen, consider when recent sinusitis or OM
• N meningitis: group living, recent exposure, rash 
• S aureus: IVDU
• HIV/immunocompromised: also consider Listeria, cryptococcus, TB
• Perform CT prior to LP if any focal deficit, seizure, AMS,  hx tumor, age > 60, papilledema 
• Give steroids (10 mg IV dexamethasone) 20 min prior to Abx as part of your empiric coverage because it decreases mortality in S pneumo 

TTP 

TTP is decreased ADAMTS-13 which cleaves vWF, without it vWF forms multimers that lead to microthrombi 

Present with fever anemia thrombocytopenia, renal failure, AMS, only 20-30% of pts have the classic pentad 

Microthrombi result in end organ damage 

Dx with plt <20K, MAHA, schistocytes, elevated retic count, LDH, unconjugated bilirubin

Normal coags and normal fibrinogen

Tx: steroids, FFP, HD can temporize 

Gold standard is PLEX which removes autoantibodies and replaces ADAMTS-13

Avoid platelet transfusion-> provokes thrombosis

Caplacizumab is a monoclonal antibody against vWF to impede interaction with platelets, very expensive.. not prescribed if plts >30K. Prescribed for prevention but may also be used in inpatient management 

Tox Review with Dr. Eisenstat

-Contraindications to activated charcoal include aspiration risk (think of toxins with high risk of seizures, somnolence, vomiting, etc)

-GHB acts on GABA receptors. Short acting. Classic case is obtunded requiring intubation then later self extubates

-Organophosphate toxicity: Tx with atropine and pralidoxime 

-Serotonin syndrome: clonus, give cyproheptadine 

-NMS give bromocriptine, malignant hyperthermia give dantrolene

-Cyanide toxicity: house fire with lactic acidosis, hypotension, bradycardia. Gives hydroxycobalamin 

-Amatoxin containing mushroom-> NAC

-Digoxin toxicity-> Don’t give calcium. 

-Indications for hyperbaric for carbon monoxide: Carboxyhemoglobin level >25% or >15 if pregnant, also anyone with LOC or severe lactic acidosis 

ID Review with Dr. Shoff

-Flexor tensynovitis-> Kanavel’s signs: pain with passive extension, percussion tenderness, uniform swelling, flexion posture

-Most common septic arthritic: Staph aureus 

-Missisppi Valley-> histoplasmosis

-Southest US-> blastomycoisis 

-California-> coccidiomycosis 

Varicella: lesions in various stages

Smallpox: lesions in same stage 

Pertussis: treat close contacts

Rabies: PEP for any bat exposure. Vaccine day 0,3,7,14. Administer immune globulin around wound, any leftover goes IM
