In 2009, during the influenza A (H1N1) epidemic, there were many reported cases of pulmonary infection with severe hypoxemia that was refractory to the ventilatory strategies and rescue therapies commonly used to treat patients with severe acute respiratory distress syndrome. Many of those cases were treated with extracorporeal membrane oxygenation (ECMO), which renewed international interest in the technique. The Extracorporeal Support Study Group was created in order to practice ECMO and to employ it in the treatment of patients with severe hypoxemia. In this article, we discuss the indications for using ECMO and report the case of a patient with refractory hypoxemia who was successfully treated with ECMO.

Objective: To determine whether mobility therapy is associated with central or peripheral catheter-related adverse events in critically ill patients in an ICU in Brazil. Methods: A retrospective analysis of the daily medical records of patients admitted to the Clinical Emergency ICU of the University of São Paulo School of Medicine Hospital das Clínicas Central Institute between December of 2009 and April of 2011. In addition to the demographic and clinical characteristics of the patients, we collected data related to central venous catheters (CVCs), hemodialysis (HD) catheters and indwelling arterial catheters (IACs): insertion site; number of catheter days; and types of adverse events. We also characterized the mobility therapy provided. Results: Among the 275 patients evaluated, CVCs were used in 49%, HD catheters were used in 26%, and IACs were used in 29%. A total of 1,268 mobility therapy sessions were provided to patients while they had a catheter in place. Catheter-related adverse events occurred in 20 patients (a total of 22 adverse events): 32%, infection; 32%, obstruction; and 32%, accidental dislodgement. We found that mobility therapy was not significantly associated with any catheter-related adverse event, regardless of the type of catheter employed: CVC-OR = 0.8; 95% CI: 0.7-1.0; p = 0.14; HD catheter-OR = 1.04; 95% CI: 0.89-1.21; p = 0.56; or IAC-OR = 1.74; 95% CI: 0.94-3.23; p = 0.07. Conclusions: In critically ill patients, mobility therapy is not associated with the incidence of adverse events involving CVCs, HD catheters, or IACs.

Extracorporeal respiratory support in adult patients

Suporte respiratório extracorpóreo em pacientes adultos

Abstract PDF PT PDF EN Portuguese Text

In patients with severe respiratory failure, either hypoxemic or hypercapnic, life support with mechanical ventilation alone can be insufficient to meet their needs, especially if one tries to avoid ventilator settings that can cause injury to the lungs. In those patients, extracorporeal membrane oxygenation (ECMO), which is also very effective in removing carbon dioxide from the blood, can provide life support, allowing the application of protective lung ventilation. In this review article, we aim to explore some of the most relevant aspects of using ECMO for respiratory support. We discuss the history of respiratory support using ECMO in adults, as well as the clinical evidence; costs; indications; installation of the equipment; ventilator settings; daily care of the patient and the system; common troubleshooting; weaning; and discontinuation.

 


Keywords: Extracorporeal membrane oxygenation; Respiratory distress syndrome, adult; Hypoxia; Hypercapnia.

Percutaneous Tracheostomy in Critically-ill Patients: The Experience of a Medical Intensive Care Unit

Traqueostomia percutânea no doente crítico: a experiência de uma unidade de terapia intensiva clínica

Abstract PDF PT

Background: Tracheostomy is a procedure commonly required in the intensive care unit. In the last two decades, the use of the percutaneous method has increased in parallel with improvements in the technique. Objective: To describe our experience in employing the percutaneous method over the last 3.5 years. Methods: We created, retrospectively, a database of prospective tracheostomy data related to 78 patients evaluated between January 2000 and July 2003. We used the percutaneous tracheostomy techniques of either progressive dilatation (in 36 patients) or forceps dilatation (in 42 patients). Data are expressed as number of occurrences or median with interquartile ranges. Results: The mean age of the patients was 66 (range, 43-75), and the median APACHE II score was 16 (range, 12-21). The median time spent on mechanical ventilation prior to tracheostomy was 14 days (range, 10-17 days). Of the 78 patients studied, 18 (23%) died while in the intensive care unit. The most common cause of admission was acute central nervous system disturbance (in 45%). Most of the tracheostomies performed were indicated due to difficulty in weaning from mechanical ventilation (in 50%) or to Glasgow Coma scores consistently lower than 8 (in 49%). Bronchoscopy was used in all but 6 of the procedures. There were complications in 33% of the procedures. The most common complication was light bleeding, without need for transfusion. No patient died due to complications arising from the procedure. Conclusion: Percutaneous tracheostomy is reasonable and safe when performed in an intensive care unit.
