          Abstract

          Introducción: En los últimos años las maniobras de reclutamiento alveolar (MR) han despertado un interés creciente por su potencial beneficio en la protección pulmonar y se han ido introduciendo en la práctica clínica. Objetivo: Describir y analizar los conocimientos sobre las MR y su aplicación en siete Unidades de Cuidado Intensivo de la ciudad de Cali - Colombia. Materiales y métodos: Estudio descriptivo de corte transversal, con una muestra intencional de 64 profesionales que laboran en siete Unidades de Cuidado Intensivo de Cali y aplican las MR. La encuesta auto-administrada constaba de trece preguntas y el periodo de aplicación fue de dos meses. Resultados: De los 64 encuestados el 77,8% sigue una guía o protocolo para realizar las MR; el 54,7% utiliza durante la MR un nivel de Presión Positiva al Final de la Espiración (PEEP) ideal que asegure una saturación > de 90% y PaO2 > de 60 mmHg; el 42,1% acepta presiones en la vía aérea entre 35 y 50 cmH2O; el 48,4% realiza las MR con aumento progresivo de la PEEP y bajo volumen corriente. Conclusiones: Se encontró heterogeneidad en las respuestas relacionadas con el conocimiento de las MR. No existe en la actualidad un consenso acerca de cuál es la forma más eficaz y segura de aplicar una MR. Este estudio puede ser el punto de partida para un llamado de atención a la revisión de los conocimientos, competencias y habilidades que se requieren para realizar las MR.

          Introduction: For the past years, alveolar recruitment maneuvers (RM) have originated a growing interest due to their beneficial potential in pulmonary protection, and have been introduced in clinical practice. Objective: Describe and analyze the knowledge of the MR and its application in seven intensive care units in the city of Cali, Colombia. Method and materials: Descriptive Cross-Sectional Study with an intentional sample of 64 professionals working in seven intensive care units and apply MR. The self-completed survey was made up of thirteen questions, and the application period was two months. Results: To perform RM, of 64 professionals survey, 77.8% of the healthcare providers that were polled follow a protocol guide, in which 54.7% answered that during RM the ideal Positive end-expiratory pressure (PEEP) is the one which maintains a saturation > 90% and a PaO2 > 60 mmHg; 42.1% tolerates airway pressures between 35 and 50 cmH2O; 48.4% perform RM with a progressive increase of the PEEP and a low tidal volume. Conclusions: Regarding the knowledge related to RM, heterogeneity was found in the answers. There is currently no consensus about which is the most effective and secure way to implement an MR. This study can be the starting point to create awareness towards the revision of knowledge, capacities and abilities that are required to perform RM.

          Positive end-expiratory pressure setting in adults with acute lung injury and acute respiratory distress syndrome: a randomized controlled trial.

          The need for lung protection is universally accepted, but the optimal level of positive end-expiratory pressure (PEEP) in patients with acute lung injury (ALI) or acute respiratory distress syndrome remains debated. To compare the effect on outcome of a strategy for setting PEEP aimed at increasing alveolar recruitment while limiting hyperinflation to one aimed at minimizing alveolar distension in patients with ALI. A multicenter randomized controlled trial of 767 adults (mean [SD] age, 59.9 [15.4] years) with ALI conducted in 37 intensive care units in France from September 2002 to December 2005. Tidal volume was set at 6 mL/kg of predicted body weight in both strategies. Patients were randomly assigned to a moderate PEEP strategy (5-9 cm H(2)O) (minimal distension strategy; n = 382) or to a level of PEEP set to reach a plateau pressure of 28 to 30 cm H(2)O (increased recruitment strategy; n = 385). The primary end point was mortality at 28 days. Secondary end points were hospital mortality at 60 days, ventilator-free days, and organ failure-free days at 28 days. The 28-day mortality rate in the minimal distension group was 31.2% (n = 119) vs 27.8% (n = 107) in the increased recruitment group (relative risk, 1.12 [95% confidence interval, 0.90-1.40]; P = .31). The hospital mortality rate in the minimal distension group was 39.0% (n = 149) vs 35.4% (n = 136) in the increased recruitment group (relative risk, 1.10 [95% confidence interval, 0.92-1.32]; P = .30). The increased recruitment group compared with the minimal distension group had a higher median number of ventilator-free days (7 [interquartile range {IQR}, 0-19] vs 3 [IQR, 0-17]; P = .04) and organ failure-free days (6 [IQR, 0-18] vs 2 [IQR, 0-16]; P = .04). This strategy also was associated with higher compliance values, better oxygenation, less use of adjunctive therapies, and larger fluid requirements. A strategy for setting PEEP aimed at increasing alveolar recruitment while limiting hyperinflation did not significantly reduce mortality. However, it did improve lung function and reduced the duration of mechanical ventilation and the duration of organ failure. clinicaltrials.gov Identifier: NCT00188058.

            Lung recruitment in patients with the acute respiratory distress syndrome.

            In the acute respiratory distress syndrome (ARDS), positive end-expiratory pressure (PEEP) may decrease ventilator-induced lung injury by keeping lung regions open that otherwise would be collapsed. Since the effects of PEEP probably depend on the recruitability of lung tissue, we conducted a study to examine the relationship between the percentage of potentially recruitable lung, as indicated by computed tomography (CT), and the clinical and physiological effects of PEEP. Sixty-eight patients with acute lung injury or ARDS underwent whole-lung CT during breath-holding sessions at airway pressures of 5, 15, and 45 cm of water. The percentage of potentially recruitable lung was defined as the proportion of lung tissue in which aeration was restored at airway pressures between 5 and 45 cm of water. The percentage of potentially recruitable lung varied widely in the population, accounting for a mean (+/-SD) of 13+/-11 percent of the lung weight, and was highly correlated with the percentage of lung tissue in which aeration was maintained after the application of PEEP (r2=0.72, P<0.001). On average, 24 percent of the lung could not be recruited. Patients with a higher percentage of potentially recruitable lung (greater than the median value of 9 percent) had greater total lung weights (P<0.001), poorer oxygenation (defined as a ratio of partial pressure of arterial oxygen to fraction of inspired oxygen) (P<0.001) and respiratory-system compliance (P=0.002), higher levels of dead space (P=0.002), and higher rates of death (P=0.02) than patients with a lower percentage of potentially recruitable lung. The combined physiological variables predicted, with a sensitivity of 71 percent and a specificity of 59 percent, whether a patient's proportion of potentially recruitable lung was higher or lower than the median. In ARDS, the percentage of potentially recruitable lung is extremely variable and is strongly associated with the response to PEEP. Copyright 2006 Massachusetts Medical Society.

              Reversibility of lung collapse and hypoxemia in early acute respiratory distress syndrome.

              The hypothesis that lung collapse is detrimental during the acute respiratory distress syndrome is still debatable. One of the difficulties is the lack of an efficient maneuver to minimize it. To test if a bedside recruitment strategy, capable of reversing hypoxemia and collapse in > 95% of lung units, is clinically applicable in early acute respiratory distress syndrome. Prospective assessment of a stepwise maximum-recruitment strategy using multislice computed tomography and continuous blood-gas hemodynamic monitoring. Twenty-six patients received sequential increments in inspiratory airway pressures, in 5 cm H(2)O steps, until the detection of Pa(O(2)) + Pa(CO(2)) >or= 400 mm Hg. Whenever this primary target was not met, despite inspiratory pressures reaching 60 cm H(2)O, the maneuver was considered incomplete. If there was hemodynamic deterioration or barotrauma, the maneuver was to be interrupted. Late assessment of recruitment efficacy was performed by computed tomography (9 patients) or by online continuous monitoring in the intensive care unit (15 patients) up to 6 h. It was possible to open the lung and to keep the lung open in the majority (24/26) of patients, at the expense of transient hemodynamic effects and hypercapnia but without major clinical consequences. No barotrauma directly associated with the maneuver was detected. There was a strong and inverse relationship between arterial oxygenation and percentage of collapsed lung mass (R = - 0.91; p < 0.0001). It is often possible to reverse hypoxemia and fully recruit the lung in early acute respiratory distress syndrome. Due to transient side effects, the required maneuver still awaits further evaluation before routine clinical application.
