Crit Care Flashcards

1
Q

16-year-old boy with a bout of emesis at a party, presenting with chest pain, dysphagia and dyspnea. His vital signs are HR 120, RR 20, BP 120/65, sats 96% on RA. He had decreased air entry on one side with subcutaneous emphysema. The CXR shows a small pneumothorax and small pneumomediastinum. What is the next step?

Oxygen
Needle decompression
Chest tube
Upper endoscopy

A

Oxygen
If oxygen wasn’t an answer, would pick consult GI for scope, or if clinically stable may pick oxygen.
Boerhaave Syndrome: life threatening–needs prompt endoscopic or surgical intervention

Q

5-year-old child with cerebral palsy. Underwent G-tube placement 2 weeks ago and has been fussy since. Restarted on regular home feed regimen of 1000mL of 2kcal/mL formula with 500 mL of water post-op. Presenting with retching and lethargy. Blood work shows: Na 127, serum Osm 264, urine Na 146, urine Osm 1016, creatinine 55. What is the diagnosis? (no indication of hydration status)
Cerebral salt wasting
Primary polydipsia (other = excessive water intake)
Inadequate salt intake
SIADH

A

Cerebral salt wasting: usually dry (perhaps why this patient is obtunded, urine Na is very high)

Urgent XR to assess location
Reassure her that children swallow things all the time
Reassess in 2 days if not in the stool

Q

A teen male has a 3 week history of worsening headache. He has a BP of 180/105. He has a history of renal scarring and asthma. On examination his neck was supple and his reflexes were brisk. What do you use to treat him?
IV nitroprusside
IV labetalol
SL nifedipine
PO amlodipine

A

SL nifedipine:

IV nitro–instantaneous onset of action, can be titrated as continuouss infusion
Nifedipine: onset of action is 30 min, contraindicated in intracerebral hemorrhage
Nelson’s: patients with acute severe symptoms and life-threatening symptoms IV drug infusion is better because decreases in BP can be carefully monitored and titrated
Less severe symptoms ex. headaches, nausea/vomitting: can use oral meds

Dr. Alsalehi:
Hypertensive urgency, not emergency. Use PO meds:

Q

symptoms of metformin overdose

A

metformin associated lactic acidosis (MALA)
large overdose interferes with liver’s ability to clear lactic acid. Can result in hemodynamic instability. Treatment is hemodialysis.

62
Q

Little kid found with empty bottle grandparent glyburide glucose 3.9
Reassure and d/c
NS +D10W
Admit and monitor for 12 hours

A

admit and monitor for 12 hrs
Glyburide is a sulfonylurea (antidote octreotide infusion). As per nelson’s should admit for serial glucose monitoring for at least 12 hours including an overnight fast. D10W infusion not recommended because stimulates more insulin release leading to prolonged hypoglycaemia. If persistent hypoglycaemia after >= 2 doses of IV dextrose, next step is octreotide. IV or SC. Sulfonylureas work by enhancing endogenous insulin secretion. Hypoglycemia can last up to 24 hours.

Q

1)Up to what age/weight should you use pediatric dose attenuator on AED?

Defib at 4J/kg
Epi IV
Defib 2J/kg
Continue CPR x 5 min

A

defibrillate at 4J/kg
AED can be used in infant and children. Manual defibrillator preferred in infants. Can use pediatric dose attenuator with AEDs up to 25kg or 8 yrs of age. Can also use standard adult defibrillator if pediatric dose attenuator not available. Can use initial shock dose of 2J/kg to 4J/kg.
