Outcomes of ventilatory asynchrony in patients with inspiratory effort. / Resultados de la asincronía ventilatoria en pacientes con esfuerzo inspiratório.

OBJECTIVE: To identify the relationship of patient-ventilator asynchrony with the level of sedation and hemogasometric and clinical results. METHODS: This was a prospective study of 122 patients admitted to the intensive care unit who underwent > 24 hours of invasive mechanical ventilation with inspiratory effort. In the first 7 days of ventilation, patient-ventilator asynchrony was evaluated daily for 30 minutes. Severe patient-ventilator asynchrony was defined as an asynchrony index > 10%. RESULTS: A total of 339,652 respiratory cycles were evaluated in 504 observations. The mean asynchrony index was 37.8% (standard deviation 14.1 - 61.5%). The prevalence of severe patient-ventilator asynchrony was 46.6%. The most frequent patient-ventilator asynchronies were ineffective trigger (13.3%), autotrigger (15.3%), insufficient flow (13.5%), and delayed cycling (13.7%). Severe patient-ventilator asynchrony was related to the level of sedation (ineffective trigger: p = 0.020; insufficient flow: p = 0.016; premature cycling: p = 0.023) and the use of midazolam (p = 0.020). Severe patient-ventilator asynchrony was also associated with hemogasometric changes. The persistence of severe patient-ventilator asynchrony was an independent risk factor for failure of the spontaneous breathing test, ventilation time, ventilator-associated pneumonia, organ dysfunction, mortality in the intensive care unit, and length of stay in the intensive care unit. CONCLUSION: Patient-ventilator asynchrony is a frequent disorder in critically ill patients with inspiratory effort. The patient's interaction with the ventilator should be optimized to improve hemogasometric parameters and clinical results. Further studies are required to confirm these results.

PROGRAM OF INTESTINAL REHABILITATION AND EARLY POSTOPERATIVE ENTERAL NUTRITION: A PROSPECTIVE COHORT STUDY.

BACKGROUND: Some factors can act on nutritional status of patients operated for a gastrointestinal cancer. A timely and appropriate nutritional intervention could have a positive effect on postoperative outcomes. AIM: To determine the effect of a program of intestinal rehabilitation and early postoperative enteral nutrition on complications and clinical outcomes of patients underwent gastrointestinal surgery for cancer. METHODS: This is a prospective study of 465 patients underwent gastrointestinal surgery for cancer consecutively admitted in an oncological intensive care unit. The program of intestinal rehabilitation and early postoperative enteral nutrition consisted in: 1) general rules, and 2) gastrointestinal rules. RESULTS: The mean age of analysed patients was 63.7±9.1 years. The most frequent operation sites were colon-rectum (44.9%), gynaecological with intestinal suture (15.7%) and oesophagus-gastric (11.0%). Emergency intervention was performed in 12.7% of patients. The program of intestinal rehabilitation and early postoperative enteral nutrition reduced major complication (19.2% vs. 10.2%; p=0.030), respiratory complications (p=0.040), delirium (p=0.032), infectious complications (p=0.047) and gastrointestinal complications (p<0.001), mainly anastomotic leakage (p=0.033). The oncological intensive care unit mortality (p=0.018), length of oncological intensive care unit (p<0.001) and hospital (p<0.001) stay were reduced as well. CONCLUSIONS: Implementing a program of intestinal rehabilitation and early postoperative enteral nutrition is associated with reduction in postoperative complications and improvement of clinical outcomes in patients undergoing gastrointestinal surgery for cancer.

Program of gastrointestinal rehabilitation and early postoperative enteral nutrition: a prospective study.

Nutritional depletion is commonly observed in patients undergoing surgical treatment for a gastrointestinal malignancy. An appropriate nutritional intervention could be associated with improved postoperative outcomes. The study was aimed to determine the effect of a program of gastrointestinal rehabilitation and early postoperative enteral nutrition upon complications and clinical outcomes in patients who experienced gastrointestinal surgery for cancer. This is a prospective study (2013 January-2015 December) of 465 consecutive patients submitted to gastrointestinal surgery for cancer and admitted to an Oncological Intensive Care Unit. The program of gastrointestinal rehabilitation and early postoperative enteral nutrition consisted on: (1) general rules: pain relive, early mobilization, antibiotic prophylaxis, deep vein thrombosis prophylaxis and respiratory physiotherapy; and (2) gastrointestinal rules: gastric protection, control of postoperative nausea and vomiting, early nasogastric tube remove and early enteral nutrition. The most frequent surgical sites were colorectal (44.9%), gynecological with intestinal suturing (15.7%) and esophagus/stomach (11.0%). Emergency surgery was performed in 12.7% of patients. The program of intestinal rehabilitation and early postoperative enteral nutrition reduced major complications (19.2 vs. 10.2%; p = 0.030), respiratory complications (p = 0.040), delirium (p = 0.032), infectious complications (p = 0.047) and gastrointestinal complications (p < 0.001). Intensive care unit mortality (p = 0.018), length of intensive care unit stay (p < 0.001) and length of hospitalization (p < 0.001) were reduced as well. A program of gastrointestinal rehabilitation and early postoperative enteral nutrition is associated with reduced postoperative complications and improved clinical outcomes in patients undergoing gastrointestinal surgery for cancer.

Resultados de la asincronía ventilatoria en pacientes con esfuerzo inspiratório / Outcomes of ventilatory asynchrony in patients with inspiratory effort

RESUMO Objetivo: Identificar la relación de la asincronía paciente-ventilador con el nivel de sedación y evaluar la asociación con los resultados hemogasométricos y clínicos. Métodos: Estudio prospectivo de 122 pacientes admitidos en la unidad de cuidados intensivos con > 24 horas de ventilación mecánica invasiva y esfuerzo inspiratorio. En los primeros 7 días de ventilación, diariamente se evaluó la asincronía paciente-ventilador durante 30 minutos. La asincronía paciente-ventilador severa se definió con un índice de asincronía > 10%. Resultados: Se evaluaron 339.652 ciclos respiratorios en 504 observaciones. La media del índice de asincronía fue 37,8% (desviación estándar 14,1% - 61,5%). La prevalencia de asincronía paciente-ventilador severa fue 46,6%. Las asincronías paciente-ventilador más frecuentes fueron: trigger ineficaz (13,3%), auto-trigger (15,3%), flujo insuficiente (13,5%) y ciclado demorado (13,7%). La asincronía paciente-ventilador severa se relacionó con el nivel de sedación (trigger ineficaz: p = 0,020; flujo insuficiente: p = 0,016; ciclado precoz: p = 0,023) y el uso de midazolam (p = 0,020). La asincronía paciente-ventilador severa se asoció con las alteraciones hemogasométricas. La persistencia de la asincronía paciente-ventilador severa fue un factor de riesgo independiente para fracaso en la prueba de ventilación espontánea, tiempo de ventilación, neumonía asociada al ventilador, disfunción de órganos, mortalidad en la unidad de cuidados intensivos y estadía en la unidad de cuidados intensivos. Conclusión: La asincronía paciente-ventilador es un trastorno frecuente en los pacientes críticos con esfuerzo inspiratorio. La interacción del paciente con el ventilador debe optimizarse para mejorar los parámetros hemogasométricos y los resultados clínicos. Se requieren otros estudios que confirmen estos resultados.
