An easily missed cause of shock
A potentially reversible cause of haemodynamic shock in critically ill patients is left ventricular outflow tract obstruction (LVOTO). We are […]

IVC collapse depends on breathing pattern
A high degree of sonographically-visualised collapse of the inferior vena cava (IVC) during inspiration suggests a volume-responsive cardiac output. This […]

Propofol and the heart
I don’t normally blog about animal studies, but on reading a review of recent(-ish) shock research I was interested in […]

Crystalloids vs colloids and cardiac output
It is said that when using crystalloids, two to four times more fluid may be required to restore and maintain […]

The right antibiotic in septic shock makes a massive difference
A retrospective review of appropriate vs inappropriate antimicrobial therapy was undertaken in over four thousand septic shock patients from multiple […]

Low PPV can still be fluid responsive
Pulse pressure variation with respiration (PPV) predicts fluid responsiveness in mechanically ventilated patients. Because this is due to transmission of […]

Collapsible IVC predicts 'low' CVP
The IVC undergoes a change in diameter during the respiratory cycle. Investigators compared the degree of sonographic IVC respirophasic diameter […]
