The relationship between lactate and thiamine levels in patients with diabetic ketoacidosis.
Thiamine functions as an important cofactor in aerobic metabolism and thiamine deficiency can contribute to lactic acidosis. Although increased rates of thiamine deficiency have been described in diabetic outpatients, this phenomenon has not been studied in relation to diabetic ketoacidosis (DKA). In the present study, we hypothesize that thiamine deficiency is associated with elevated lactate in patients with DKA. ⋯ Patients with DKA had a high prevalence of thiamine deficiency. Thiamine levels were inversely related to lactate levels among patients with DKA. A study of thiamine supplementation in DKA is warranted.

Surgical rib fixation for flail chest deformity improves liberation from mechanical ventilation.
The goal of this study was to determine the impact of surgical rib fixation (SRF) in a treatment protocol for severe blunt chest trauma. ⋯ Surgical rib fixation resulted in a significant decrease in ventilator days and may represent a novel approach to decreasing morbidity in flail chest patients when used as a rescue therapy in patients with declining pulmonary status. Larger studies are required to further identify these benefits.

Indications and outcomes in children receiving renal replacement therapy in pediatric intensive care.
We aimed to describe patient characteristics, indications for renal replacement therapy (RRT), and outcomes in children requiring RRT. We hypothesized that fluid overload, not classic blood chemistry indications, would be the most frequent reason for RRT initiation. ⋯ Hemodynamic instability and multiorgan dysfunction syndrome are the most common clinical conditions associated with acute kidney injury in our population. In the population studied, the mortality was lower than previously reported in children and much lower than in the adult population.

Impairment of thrombin generation in the early phases of the host response of sepsis.
The purpose was to investigate the presence of hypercoagulability in the very early phase of the host response to an infection in the clinical course of sepsis and septic shock. ⋯ Patients with sepsis and febrile neutropenia present an impairment in thrombin generation from very early stages of their disease course. These results suggest that the procoagulant in vitro alterations described during sepsis do not necessarily translate into a clinically relevant systemic hypercoagulable state. These findings could help explain why treatment with systemic anticoagulants did not translate to clinical benefits in human sepsis and highlight the need for a better understanding of the hemostatic alterations in sepsis before new treatments targeting coagulation activation are developed.

Clinically manifest thromboembolic complications of femoral vein catheterization for continuous renal replacement therapy.
The safety of femoral vein (FV) catheterization for continuous renal replacement therapy is uncertain. We sought to determine the incidence of clinically manifest venous thromboembolism (VTE) in such patients. ⋯ The incidence of clinically manifest VTE after FV catheterization with high flow catheters is low and lower to that seen in general ICU patients.
