A 23yr presents following a syncope, he denies chest pain. The following ECG is taken:
What does this ECG demonstrate?
What are the important differential diagnoses in a young adult with syncope?
Lab case 454
2-year-old boy brought to ED by ambulance as category 1 for severe croup. His blood gases showed the following.
PH = 7.39
Lab case 453 interpretation
PH = 6.782, that is severe acidaemia.
HCO3 = 2.5 mmol/L, that is extremely low. So we have metabolic acidosis.
Next we need to calculate the compensation and find out what type of metabolic acidosis this patient has.
Imaging Case of the Week 611
The x-ray is from a toddler with fever and abdominal pain. What can be seen? Continue reading
ECG of the week 27th November
The following ECG is from a 62-year-old man who presented following an MVA. He has collided with a tree at 80km/hr with impact to his anterior chest wall on the steering wheel and significant cabin intrusion requiring extrication.
He is complaining of central chest pain and dyspnoea and is unable to recount how the accident occurred. He is hemodynamically stable.
His ECG is performed:
Describe and interpret his ECG. How will you manage this patient?
Lab case 453
72 year-year-old man with history of type II DM and has a single kidney. Presented with 2 weeks of diarrhoea. He has been in bed for 2 weeks. Unresponsive. Last proper meal was 2 weeks ago. His Venous blood gases showed the following:
PH = 6.782
pCO2 = 17 mmHg
pO2 = 75 mmHg
Lab case 452 interpretation
Question 1:
PH = 7.30, that is mild acidaemia.
HCO3 = 18, that is low (less than 24), So we have metabolic acidosis.
Once we have metabolic acidosis, next step is to calculate compensation and anion gap.
