Reevaluation of the utilization of arterial blood gas analysis in the Intensive Care Unit: Effects on patient safety and patient outcome.
Arterial blood gas (ABG) analysis is a useful tool to evaluate hypercapnia in the context of conditions and diseases affecting the lungs. Oftentimes, indications for ABG analysis are broad and nonspecific and lead to frequent testing without test results influencing patient management. ⋯ A significant decrease of ABGs obtained in the ICU does not negatively impact patient outcome and safety. A decrease in the number of ABGs per patient allows cost-efficient patient care with a lower risk for complications.

Multicenter StudyMulticenter evaluation of pharmacologic management and outcomes associated with severe resistant alcohol withdrawal.
A subset of patients with alcohol withdrawal syndrome does not respond to benzodiazepine treatment despite escalating doses. Resistant alcohol withdrawal (RAW) is associated with higher incidences of mechanical ventilation and nosocomial pneumonia and longer intensive care unit (ICU) stay. The objective of this study is to characterize pharmacologic management of RAW and outcomes. ⋯ Diverse patterns exist in the management of patients meeting RAW criteria, indicating lack of refined approach to treatment. High doses of sedatives used for these patients may result in a high level of care, illustrating a need for evidence-based clinical guidelines to optimize outcomes.

Candidemia-induced pediatric sepsis and its association with free radicals, nitric oxide, and cytokine level in host.
Candida species has become the seventh most frequent causal microorganisms of nosocomial sepsis. Prematurity and low birth weights are strongly associated with the development of neonatal nosocomial bloodstream infections. Candida albicans has been the species most often associated with neonatal infections, but recently, there has been a changing pattern in the isolates recovered from neonates with invasive candidiasis, which poses resistance to the existing class of azoles such as fluconazole antifungals along with cross resistance to newer triazoles, which results in a therapeutic challenge in invasive fungal infections causing high incidence of mortality. ⋯ Furthermore, the change in free radical, cytokine release, and nitric oxide synthase expression and nitric oxide release from polymorphonuclear leukocytes isolated from control and pediatric sepsis cases were also performed. The present study probably for the first time reports the change in increasing incidence of nonalbicans Candida-induced sepsis in neonates and children admitted to the intensive care unit of hospital, and current antibiotics load posing resistance for antifungal treatment strategy and provide serious threats in future treatment. The increase in free radicals in polymorphonuclear leukocytes and increase in expression of nitric oxide synthase expression and nitric oxide release in Candida-infected pediatric sepsis cases underlie the role of host factor in dissemination and invasiveness of infection from exogenous sources and pathogenesis of systemic inflammation during sepsis.

Observational StudyPredictive value of the complement system for sepsis-induced disseminated intravascular coagulation in septic patients in emergency department.
To investigate changes in circulating complement component C3, membrane attack complex (MAC), and mannose-binding lectin (MBL) in patients with sepsis-induced disseminated intravascular coagulation (DIC). ⋯ Complement 3, MAC, and MBL were significantly increased in septic patients with DIC. Membrane attack complex independently predicted sepsis-induced DIC and development of DIC after ED admission.

Randomized Controlled Trial Multicenter StudyInsulin infusion therapy in critical care patients: Regular insulin vs short-acting insulin. A prospective, crossover, randomized, multicenter blind study.
The aim of this multicenter, prospective, randomized, crossover trial is to compare, in critical care patients receiving insulin infusion therapy (IIT), the pharmacodynamic of Humulin insulin (Hlin), currently used as "standard of care," and Humalog insulin (Hlog), a shorter acting insulin formulation. This was measured as extent and duration of the carryover effect of insulin treatment, with the latter calculated as ratio between blood glucose concentration (BGC) reduction during and after IIT. ⋯ The use of constant Hlog infusion for IIT, when compared with Hlin at the same dose, is associated with a less profound carryover effect on BGC after discontinuation of IIT, a briefer duration of carryover, a faster BGC drop during infusion, and a quicker BGC rise after discontinuation. These characteristics suggest that Hlog IIT may be preferable for use in critically ill patients.
