Multicenter Study Comparative Study Clinical Trial
Fever and fever management among intensive care patients with known or suspected infection: a multicentre prospective cohort study.
To describe the duration of fever, fever management, and outcomes among intensive care patients with fever and known or suspected infection. ⋯ We have described the typical time course of fever in an easily identified cohort of patients with known or suspected infection and have determined that these patients have significant morbidity and mortality. This information is vital to the design of interventional studies for the treatment of fever in ICU.

Case Reports Comparative Study
Comparison of intermittent haemodialysis, prolonged intermittent renal replacement therapy and continuous renal replacement haemofiltration for lithium toxicity: a case report.
This case report compares three types of renal replacement therapy for acute severe lithium toxicity and is the first to use prolonged intermittent renal replacement therapy (PIRRT). A peak lithium level of 13.2mmol/L was recorded after a 51- year-old man attempted suicide. ⋯ Expected efficacy of treatment with a single daily session of PIRRT was higher than IHD or CVVH. PIRRT is a useful strategy for dialysis among patients with acute lithium intoxication.

Comparative Study
Calcium flux in continuous venovenous haemodiafiltration with heparin and citrate anticoagulation.
Calcium chelation with citrate is an effective alternative to heparin for anticoagulation of the extracorporeal circuit during continuous venovenous haemodiafiltration (CVVHD-F). Calcium release occurs upon citrate metabolism; however, ultrafiltration of citrate-bound and free ions also occurs. ⋯ Despite supplementation to maintain arterial iCa(2+) levels, citrate anticoagulation results in a net calcium deficit. An equation for estimating required citrate dose may allow revision of citrate dosing protocols.

Comparative Study
Increased blood volume following resolution of acute cardiogenic pulmonary oedema: a retrospective analysis.
Acute cardiogenic pulmonary oedema (APO) occurs due to an increase in pulmonary microvascular pressure and massive transvascular fluid filtration into the lungs, causing respiratory insufficiency. ⋯ Patients with APO are hypovolaemic at the onset relative to their state after treatment. With treatment and resolution of APO, hypovolaemia is corrected and circulating volume is restored.

The development of specialised airway tools help laryngoscopists secure the airway in intensive care units. The use of videolaryngoscopy has been suggested in simulation studies, and human studies suggest that this advanced airway tool may have an advantage for difficult airways; however, less is known about its use in the ICU. ⋯ The use of a new airway tool may not necessarily lead to immediate reduction in attempts at orotracheal intubation or in overall complication rates.
