Randomized Controlled Trial
A pilot randomised controlled trial evaluating the pharmacodynamic effects of furosemide versus acetazolamide in critically ill patients.
To compare the physiological and biochemical effects of a single intravenous dose of furosemide or acetazolamide in critically ill patients. ⋯ Furosemide is a more potent diuretic and chloriuretic agent than acetazolamide in critically ill patients, and achieves a threefold greater negative fluid balance. Compared with acetazolamide, furosemide acidifies urine and alkalinises plasma. Our findings imply that combination therapy might be a more physiological approach to diuresis in critically ill patients.

Randomized Controlled Trial
Pharmacokinetic data support 6-hourly dosing of intravenous vitamin C to critically ill patients with septic shock.
To study vitamin C pharmacokinetics in septic shock. ⋯ Intravenous vitamin C (1.5 g every 6 hours) corrects vitamin C deficiency and hypovitaminosis C and provides an appropriate dosing schedule to achieve and maintain normal or elevated vitamin C levels in septic shock.
