Enteral nutrition in critically ill patients under vasoactive drug therapy: The NUTRIVAD study.

BACKGROUND: Enteral nutrition (EN) in critically ill patients requiring vasoactive drug (VAD) support is controversial. This study assesses the tolerability and safety of EN in such patients. METHODS: This prospective observational study was conducted in 23 intensive care units (ICUs) over 30 months. Inclusion criteria were a need for VADs and/or mechanic circulatory support (MCS) over a minimum of 48 h, a need for ≥48 h of mechanical ventilation, an estimated life expectancy >72 h, and ≥72 h of ICU stay. Patients with refractory shock were excluded. EN was performed according to established protocols during which descriptive, daily hemodynamic and efficacy, and safety data were collected. An independent research group conducted the statistical analysis. RESULTS: Of 200 patients included, 30 (15%) required MCS and 145 (73%) met early multiorgan dysfunction criteria. Mortality was 24%. Patients needed a mean dose of norepinephrine in the first 48 h of 0.71 mcg/kg/min (95% CI, 0.63-0.8) targeting a mean arterial pressure of 68 mm Hg (95% CI, 67-70) during the first 48 h. EN was started 34 h (95% CI, 31-37) after ICU admission. Mean energy and protein delivered by EN/patient/day were 1159 kcal (95% CI, 1098-1220) and 55.6 g (95% CI, 52.4-58.7), respectively. Daily energy balance during EN/patient/day was -432 (95% CI, -496 to -368). One hundred and fifty-four (77%) patients experienced EN-related complications. However, severe complications, such as mesenteric ischemia, were recorded in only one (0.5%) patient. CONCLUSION: EN in these patients seems feasible, safe, and unrelated to serious complications. Reaching the energy target only through EN is difficult.

[Emergency treatment for traumatic cardiac arrest: prognostic factors and hospital outcome]. / Factores pronóstico y resultados intrahospitalarios de la parada cardiaca traumática atendida en un servicio de urgencias.

OBJECTIVES: To identify prehospital and on-arrival factors associated with hospital outcome in patients with traumatic cardiac arrest (TCA) discharged with recovered spontaneous circulation from the emergency department. MATERIAL AND METHODS: Multipurpose prospective cohort study of patients with TCA who recovered after treatment at a tertiary care hospital emergency department between 2003 and 2016. We gathered data on epidemiologic variables, type and cause of injuries, and prehospital and hospital emergency care. The outcome was overall hospital mortality. RESULTS: A total of 130 TCA cases were included; 123 patients (94.6%) had received blunt trauma injuries and 65 (50%) had been in traffic accidents. The mean (SD) age was 39 (16) years, and 96 (73.8%) were male. Fifty patients (65%) were in asystole and 42 (32.3%) had pulseless electrical activity. Sixteen (12.3%) survived to be discharged; 13 of the survivors (81.3%) had recovered neurological activity. Factors that were independently associated with hospital mortality were asystole on arrival of first responders (odds ratio [OR], 25; 95% CI, 2.5-247; P=.006), nonreactive pupils on arrival at the hospital (OR, 13; 95% CI, 2.0-79; P=.006), and an Injury Severity Score over 25 (OR, 13; 95% CI, 1.8-94; P=.011). CONCLUSION: Twelve percent of patients in this cohort survived to discharge after TCA and 8 out of 10 of the surviving patients recovered neurologically. Asystole at start of prehospital care, nonreactive pupils on hospital arrival, and a severity score over 25 may indicate poor prognosis after TCA.

OBJETIVO: Identificar los factores pronóstico a la llegada a urgencias y los resultados al alta hospitalaria de los pacientes en parada cardiaca traumática (PCT), documentada por un servicio de emergencias médicas (SEM), con posterior recuperación de la circulación espontánea (RCE). METODO: Estudio de cohorte multipropósito de pacientes con PCT recuperada atendidos en un servicio de urgencias (SU) de un hospital universitario de tercer nivel de 2003 a 2016. Se recogieron variables epidemiológicas, tipo y mecanismo del traumatismo, datos de la atención extrahospitalaria y del SU. La variable de resultado fue la mortalidad global intrahospitalaria. RESULTADOS: Se incluyeron 130 PCT, de los cuales 123 (94,6%) sufrieron un traumatismo cerrado y 65 (50%) tuvieron un accidente de tráfico. La edad media fue de 39 (DE 16) años y 96 (73,8%) fueron varones. Cincuenta pacientes (65%) presentaron asistolia y 42 (32,3%) actividad eléctrica sin pulso (AESP). Dieciséis (12,3%) sobrevivieron al alta, de los cuales 13 (81,3%) tuvieron recuperación neurológica favorable. Un ritmo de asistolia en la primera atención de extrahospitalaria (OR = 25; IC 95% 2,5-247; p = 0,006), las pupilas arreactivas a la llegada al hospital (OR = 13; IC 95% 2,0-79; p = 0,006), y una puntuación > 25 de la Injury Severity Score (ISS) (OR = 13; IC 95% 1,8-94; p = 0,011) se asociaron de forma independiente con la mortalidad intrahospitalaria. CONCLUSIONES: En nuestra serie, la supervivencia intrahospitalaria de la PCT fue un 12% siendo la recuperación neurológica favorable en ocho de cada diez vivos. El ritmo inicial en asistolia en la atención extrahospitalaria, la pupilas arreactivas a la llegada al hospital y una puntuación > 25 de ISS podrían implicar un mal pronóstico.

An intensive lung donor treatment protocol does not have negative influence on other grafts: a multicentre study.

OBJECTIVES: Competing requirements for organ perfusion may call for antagonistic strategies such as fluid replacement or high positive end-expiratory pressure. We recently proposed an intensive lung donor treatment protocol that nearly tripled lung procurement rates and validated it in a multicentre study. The next step was to evaluate the impact of our proposal on the other organ grafts recovered from lung donors and on the recipients' outcome after transplantation of those grafts. METHODS: A quasi-experimental study was conducted in six Spanish hospitals during 2013 (2010-12 was historical control). Organ donor management was led by a trained and experienced intensive care staff. RESULTS: A total of 618 actual donors after brain death (DBDs) were included, 453 DBDs in the control period (annual average 151) and 165 in the protocol period. No baseline differences were found between the periods. Heart, liver, kidney and pancreas retrieval rates were similar in both periods, and heart, liver, kidney and pancreas recipients' survival at 3 months showed no differences between both periods. CONCLUSIONS: Our lung donor treatment protocol is safe for other grafts obtained from donors undergoing these procedures with the aim of increasing lungs available for transplantation. It has no negative impact on the recovery rates of other grafts or on early survival of heart, liver, pancreas or kidney recipients.

Enteral Nutrition in Patients Receiving Mechanical Ventilation in a Prone Position.

BACKGROUND: Patients treated with mechanical ventilation in the prone position (PP) could have an increased risk for feeding intolerance. However, the available evidence supporting this hypothesis is limited and contradictory. OBJECTIVE: To examine the feasibility and efficacy of enteral nutrition (EN) support and its associated complications in patients receiving mechanical ventilation in PP. METHODS: Prospective observational study including 34 mechanically ventilated intensive care patients who were turned to the prone position over a 3-year period. End points related to efficacy and safety of EN support were studied. RESULTS: In total, more than 1200 patients were admitted to the intensive care unit over a period of 3 years. Of these, 34 received mechanical ventilation in PP. The mean days under EN were 24.7 ± 12.3. Mean days under EN in the supine position were significantly higher than in PP (21.1 vs 3.6; P < .001), but there were no significant differences in gastric residual volume adjusted per day of EN (126.6 vs 189.2; P = .054) as well as diet volume ratio (94.1% vs 92.8%; P = .21). No significant differences in high gastric residual events per day of EN (0.06 vs 0.09; P = .39), vomiting per day of EN (0.016 vs 0.03; P = .53), or diet regurgitation per day of EN (0 vs 0.04; P = .051) were found. CONCLUSIONS: EN in critically ill patients with severe hypoxemia receiving mechanical ventilation in PP is feasible, safe, and not associated with an increased risk of gastrointestinal complications. Larger studies are needed to confirm these findings.
