Blood purification in the critically ill patient. Prescription tailored to the indication (including the pediatric patient).

We maintain a dynamic position on extracorporeal blood purification therapies (EBPT). Continuous therapies are of choice in the hemodynamically unstable patient. We recommend their early introduction in the course of the disease, and starting with a dose of 30-35mL/kg/h. Above all, however, daily re-evaluation is required of the hemodynamic and metabolic situation and water balance of our patients in order to allow dynamic dose adjustment. Some data suggest that continuous EBPT can favorably influence the clinical course of our patients, even in the absence of acute kidney injury. The potential usefulness of hemofiltration at doses higher than the conventional doses (continuous ultrafiltration >50mL/kg/h or pulses of at least 4h a day to more than 100dosesmL/kg/h) for achieving blood purification has also been commented. We review the possible indications of this technique, together with the peculiarities of implementing these therapies in children.

Research priorities in perioperative fluid therapy and hemodynamic monitoring: A Delphi Consensus Survey from the Fluid Therapy and Hemodynamic Monitoring Subcommittee of the Hemostasis, Transfusion Medicine and Fluid Therapy Section (SHTF) of the Spanish Society of Anesthesiology and Critical Care (SEDAR).

BACKGROUND: Research in fluid therapy and perioperative hemodynamic monitoring is difficult and expensive. The objectives of this study were to summarize these topics and to prioritize these topics in order of research importance. METHODS: Electronic structured Delphi questionnaire over three rounds among 30 experts in fluid therapy and hemodynamic monitoring identified through the Fluid Therapy and Hemodynamic Monitoring Subcommittee of the Hemostasis, Transfusion Medicine and Fluid Therapy Section of the Spanish Society of Anesthesiology and Critical Care. RESULTS: 77 topics were identified and ranked in order of prioritization. Topics were categorized into themes of crystalloids, colloids, hemodynamic monitoring and others. 31 topics were ranked as essential research priority. To determine whether intraoperative hemodynamic optimization algorithms based on the invasive or noninvasive Hypotension Prediction Index versus other management strategies could decrease the incidence of postoperative complications. As well as whether the use of renal stress biomarkers together with a goal-directed fluid therapy protocol could reduce hospital stay and the incidence of acute kidney injury in adult patients undergoing non-cardiac surgery, reached the highest consensus. CONCLUSIONS: The Fluid Therapy and Hemodynamic Monitoring Subcommittee of the Hemostasis, Transfusion Medicine and Fluid Therapy Section of the Spanish Society of Anesthesiology and Critical Care will use these results to carry out the research.

Plasmapheresis as treatment for hyperlipidemic pancreatitis.

BACKGROUND: Severe hypertriglyceridemia with an accumulation of chylomicrons and triglyceride figures >1000 mg/dL can cause acute pancreatitis, a potentially fatal complication. The option of rapid reduction in triglyceride concentrations is attractive and possible with plasmapheresis. METHODS: We present the results of an analysis of 11 patients admitted to the intensive care unit with severe hypertriglyceridemic pancreatitis and treated with plasmapheresis. The procedure was repeated until serum triglycerides were below 1000 mg/dL. We recorded anthropometric, clinical data as well as final outcome. RESULTS: In eight patients a single plasma exchange was sufficient to reduce triglyceride figures <1000 mg/dL. Only three patients died, all with the worst severity indexes and who experienced the longest delay before the procedure. CONCLUSIONS: Our results, together with a review of the literature, confirm the need for a randomized clinical trial to compare conventional treatment vs. plasmapheresis in patients with severe hypertriglyceridemic pancreatitis.

[Utility of plasmapheresis in intensive care]. / Utilidad de la plasmaféresis en cuidados intensivos.

We discuss the plasmapheresis (PE) carried out in an 18-bed polyvalent intensive care unit between the years 2003-2007. This article aims to report our experience in plasmapheresis performed with specific monitors for continuous renal replacement therapy (CRRT) that shows the versatility of the use of these procedures in intensive care. The utility of these procedures include many different critical disease settings in our units (neurology, hematology, and rheumatology patients). In short, our experience in PE has led us to the conclusion that plasmapheresis is a simple extracorporeal depuration treatment that can be performed by staff trained in intensive care at any moment within a wide spectrum of clinical indications, with CRRT monitors and with minimum adverse effects.

[Cor pulmonale-PHT secondary to crest syndrome. Treatment with slow continuous ultrafiltration]. / Cor pulmonale hipertensión pulmonar secundaria a síndrome crest. Tratamiento con ultrafiltración lenta continua.

Pulmonary hypertension is a severe disease with complex treatment based on general measurements, anticoagulation and use of specific vasodilator drugs. Right heart failure initiated in final stages of the disease is treated with diuretics. We present the case of slow continuous ultrafilitration as treatment in right heart failure secondary to pulmonary hypertension associated to collagen disease refractory to diuretic treatment.
