Manejo de la defoliación y fertilización nitrogenada en pasto llorón, Eragrostis curvula, cv. Tanganyka : 1-rendimiento de materia seca, digestibilidad in vitro y rendimiento de materia seca digestible

p.7-14En una pradera de pasto llorón ubicada en Argerich se estudió el efecto de dos tratamientos de defoliación y tres niveles de fertilización nitrogenada durante tres ciclos consecutivos. El forraje se cortó con una frecuencia de 35 cm de altura o acumulado, hasta el 20 de febrero (primavera-verano), y sus rebrotes otoñales se cortaron en invierno (diferido). En primavera-verano el corte a 35 cm, produjo en promedio más materia seca que el acumulado y en el diferido a la inversa. Sus totales anuales fueron similares. La fertilización aumentó los rendimientos promedios parciales y totales (P menor a 0,05). La digestibiüdad primavera-estival fue mayor con cortes a 35 cm que en el acumulado y ambos tratamientos de defoliación respondieron al nitrógeno pero en sus diferidos el efecto fue de pequeña magnitud. Los rendimientos de materia seca digestible siguieron la misma tendencia que los de materia seca aunque, por influencia primavera-estival, en el total anual el corte a 35 cm superó al acumulado (P menor a 0,05). El rebrote primaveral sólo mostró un efecto residual parcial del fertilizante

Spontaneous-timed versus controlled noninvasive ventilation in chronic hypercapnia – a crossover trial

Jens Kerl, Ekkehard Höhn, Dieter Köhler, Dominic DellwegDepartment for Pulmonary Medicine, Intensive Care Medicine and Sleep Medicine, Fachkrankenhaus Kloster Grafschaft GmbH, Schmallenberg, 57392, GermanyBackground: There is an ongoing debate about optimal ventilator modes and settings during noninvasive ventilation (NIV).Objectives: To compare the effect of spontaneous-timed (ST) and controlled NIV on carbon dioxide reduction in patients suffering from chronic hypercapnia.Methods: Night and daytime blood gas analysis, lung function tests and 6 minute walking distance tests (6MWD) were done before and after every 6-week treatment.Results: This randomized prospective crossover trial included 42 patients. Pooled data analysis showed a decrease of nocturnal CO2 from 54.8±5.9 mmHg to 41.6±5.5 mmHg during ST ventilation (p<0.01) and from 56.2±7.5 mmHg to 42.7±5.4 mmHg during controlled NIV (p<0.01) with no difference between treatment forms (p=0.30). Daytime CO2 levels decreased from 49.3±5.5 mmHg to 45.6±4.5 mmHg when spontaneous timed ventilation was applied (p<0.01) and from 52.2±6.8 mmHg to 44.9±21114.4 mmHg in case of controlled ventilation (p<0.01) The amount of CO2 reduction was 3.8±5.6 mmHg after ST mode and 7.3±6.8 mmHg controlled ventilation (p<0.05). Nocturnal ventilator use was 5.7±2.1 and 6.7±2.3 hours for ST and controlled ventilation respectively (p=0.02). There was no effect on walking distance and lung function.Conclusion: Controlled NIV showed improved compliance compared to ST ventilation. We observed similar CO2 reductions during nocturnal ventilation, however controlled ventilation achieved a higher reduction of daytime CO2 levels.Keywords: noninvasive mechanical ventilation, clinical trials, respiratory failure, reversible hypercapnia, ventilator mode, controlled ventilatio
