A new study found that a 'lung open ventilation' strategy combining low tidal volumes, recruitment maneuvers, and high PEEP levels reduced the rates of severe persistent low oxygen levels and needed rescue therapies. The study also showed improved lung function and reduced organ failure duration.
A study of 2,471 patients with venous thrombosis found a three-fold greater relative risk associated with minor leg injuries that don't require surgery or extended bed rest. These injuries may increase blood clotting risk due to reduced activity and damage to blood vessel walls.
Patients with acute lung injury treated at ICUs requiring board-certified critical care physicians have a one-third lower mortality rate compared to those at open ICUs. This study, which analyzed data from nearly 1,100 patients, suggests that intensivist staffing improves patient outcomes.
Researchers found a moderate increase in risk of coronary heart disease associated with very low estimated glomerular filtration rate, according to a new prospective study and systematic review published in PLOS Medicine. The study suggests that renal function may be an important factor in the development of cardiovascular disease.
Researchers at Yale University found that Ang2 protein levels are higher in patients with acute lung injury and pulmonary edema. The study suggests that modulating Ang2 levels may help control acute lung injury, offering new potential therapeutic targets.
Researchers at the University of Illinois College of Medicine identified a molecule that plays a critical role in lung tissue recovery following severe injury. The study found that FoxM1, a protein controlling cell proliferation, is involved in endothelial regeneration and barrier integrity restoration.
Researchers discovered that a balance of low tidal volume and periodic deep inflation, or 'sighs,' is necessary to maintain open lungs while preventing ventilation-induced lung injury. The study found that overdoing 'sighs' can lead to further injury, highlighting the importance of finding an optimal frequency range for deep inflation.
Researchers found that a conservative fluid management strategy improved lung function, shortened mechanical ventilation time, and reduced intensive care unit days without increasing organ failure risk. The study suggests that using less fluid may be more beneficial for patients with acute lung injury or respiratory distress syndrome.
