[Transpyloric enteral nutrition in critically-ill children (I): technic and indications]. / Nutrición enteral transpilórica en el niño críticamente enfermo (I): técnica e indicaciones.

OBJECTIVE: To study the utility and efficacy of transpyloric enteral nutrition (TEN) in critically-ill children by analyzing the factors that determine enteral tolerance. PATIENTS AND METHODS: We performed a prospective, observational study between 1994 and 2002 of all critically-ill children admitted to our pediatric intensive care unit who received TEN. The indications for enteral nutrition, type of nutrition and its duration were studied. RESULTS: A total of 286 patients (8.4 % of patients admitted to the PICU in the study period), aged between 3 days and 17 years received TEN. Fifty-five children (19.2 %) were aged less than 1 month and 165 (27.7 %) were aged less than 6 months. Seventy percent received TEN exclusively. The most frequent indication for TEN was mechanical ventilation in 255 children (89.2 %). One hundred seventy-six patients (61.5 %) received TEN in the postoperative period after cardiac surgery. The mean duration of TEN was 15.4 25 days, the maximum volume of nutrition was 118.7 41 ml/kg/day, and the maximum caloric intake was 88.6 26.7 kcal/kg/day. During TEN, 227 patients received sedation (79.3 %), and 124 were administered muscle relaxants (43.3 %), with no increase in complications. CONCLUSIONS: TEN is a useful method of nutrition in critically-ill children.

[Transpyloric enteral nutrition in critically-ill children (II): complications]. / Nutrición enteral transpilórica en el niño críticamente enfermo (II): complicaciones.

OBJECTIVE: To study tolerance to transpyloric enteral nutrition (TEN) and the incidence of secondary complications in critically-ill children. PATIENTS AND METHODS: We performed a prospective, observational study between 1994 and 2002 of all critically-ill children admitted to our pediatric intensive care unit who received TEN. Tolerance and complications were analyzed. RESULTS: Of 286 patients aged between 3 days and 17 years who received TEN, gastrointestinal complications occurred in 13.6 %, abdominal distention and/or excessive gastric residue in 8 % and diarrhea in 6.3 %. Diarrhea was associated with shock (p 0.01), abdominal distension and/ or excessive gastric residue (p 0.008), hypophosphatemia (p 0.001), and duration of TEN (p < 0.001). TEN was discontinued in 2.1 % of the patients because of gastrointestinal complications. Thirty-two patients (11.2 %) died during TEN. No relationship was found between the characteristics of nutrition and complications and mortality. CONCLUSIONS: TEN is a well tolerated method of nutrition in critically-ill children that produces few complications.

[Treatment of septic shock with continuous plasmafiltration and hemodiafiltration]. / Tratamiento del shock séptico con plasmafiltración y hemodiafiltración continuas simultáneas.

Despite recent therapeutic advances, mortality due to septic shock remains high. The most important causes of mortality are refractory shock, uncontrollable alterations of coagulation, and multiorgan failure. Some authors have proposed the early use of plasmafiltration and high flow hemodiafiltration for refractory septic shock. Most authors initiate treatment with a short session of plasmafiltration followed by continuous hemodiafiltration. A 13-year-old girl presented refractory meningococcal septic shock, disseminated intravascular coagulation, and acute renal failure unresponsive to volume expansion and high doses of adrenalin and noradrenaline. She received simultaneous treatment with plasmafiltration and continuous venovenous hemodiafiltration for 30 hours. Two pumps of extrarenal purification placed in parallel through the same double line catheter were used. Fast hemodynamic stabilization and control of the coagulopathy were achieved. The patient survived with progressive recovery of renal function but required amputation of the inferior left limb. Continuous plasmafiltration and venovenous hemodiafiltration can be used simultaneously for the treatment of older children with septic shock, severe coagulopathy, and hypervolemia.

[Domiciliary mechanical ventilation in children: a Spanish multicentre study]. / Ventilación mecánica domiciliaria en niños: estudio multicéntrico español.

INTRODUCTION: Domiciliary mechanical ventilation (DMV) use is increasing in children. Few studies have analysed the characteristics of patients using this technique. MATERIALS AND METHODS: An observational, descriptive, transversal, multicentre study was conducted on patients between 1 month and 16 years of age dependent on domiciliary mechanical ventilation. RESULTS: A total of 163 patients with a median age of 7.6 years from 17 Spanish hospitals were studied. The main reasons for DMV were neuromuscular disorders. The median age at beginning of DMV was 4.6 years. Almost three-quarters (71.3%) received non-invasive ventilation. Patients depending on invasive ventilation were younger, started DMV at an earlier age, and had more hours of mechanical ventilation per day. The large majority (80.9%) used DMV during sleep time only, and 11.7% during the whole day. Only 3.4% of patients had external health assistance. Just under half (48.2%) were being followed up in specific DMV or multidisciplinary clinics. Almost three-quarters (72.1%) of patients attended school (42.3% with adapted schooling). Only 47.8% of school patients had specific caregivers in their schools. CONCLUSIONS: DMV in children is used in a very heterogeneous group of patients, and in an important number of patients it is started before the third year of life. Despite there being a significant proportion of patients with a high dependency on DMV, few families receive specific support at home or at school, and health care surveillance is variable and poorly coordinated.

[Evaluation of a paediatric critical care training program for residents in paediatrics]. / Evaluación de un programa de formación en cuidados intensivos pediátricos para residentes de pediatría.

OBJECTIVE: To evaluate a training program in paediatric critical care for residents in paediatrics. METHODS: Description of a paediatric critical care training program for residents in paediatrics. To evaluate the results of the program an initial, and final written test, an evaluation by the physician responsible for the program, a self-evaluation by the residents, and a written survey on the quality of the training program, were performed. RESULTS: From April 1998 to August 2009, 156 residents were included in the training program. All residents showed an improvement between the initial and final written test; initial score (5.6+/-1.2), final score (8.6+/-0.7) (P<0.001). Only 14.1% of the residents answered at least 70 % of the questions correctly in the initial test, compared with 96.6 % in the final test (P<0.001). The score in final test was significantly higher than the self-evaluation by the residents (6.7+/-1.2) and the evaluation by the tutor (6.9+/-0.9) (P<0.001). There were no differences between the practical self-evaluation by the residents (6.2+/-1.0) and the practical evaluation by the tutor (6.7+/-0.9). Residents considered the training program as adequate: theoretical education (8.5+/-0.8), resident handbook (9+/-0.9), practical training (8.3+/-1.0), investigation (7.6+/-2.0) and human relationship (9.2+/-0.9). CONCLUSIONS: This training program is an useful educational method for training paediatric intensive care residents. The evaluation of the training program is essential to improve the education in paediatric residents.

[Burnout among Spanish pediatricians specialized in intensive care]. / Situación de burnout de los pediatras intensivistas españoles.

BACKGROUND: The burnout syndrome is characterized by emotional exhaustion, depersonalization and decrease or loss of the feeling of personal accomplishment. It is frequent in the helping professions where an intense involvement with people needing assistance occurs. In its origin, the work policy factors seem to be important. METHODS: 68 pediatric intensive care physicians of the Intensive Care Section of the Spanish Pediatric Association participate in the study. A general questionnaire and a Spanish version of the Maslach Burnout Inventory was used. The statistical analysis includes: a descriptive analysis, the Student t-test, and the analysis of the variance. RESULTS: Burnout scores were in the average range (41,9 +/- 7,5), with a more important grade in the decrease of personal accomplishment dimension (18,9 +/- 3,5). The 55,9% of the responders attributed to the conflict with the managing policy, their work unsatisfaction and the 58,8% planned to leave the job in the future. CONCLUSIONS: The importance of burnout and its three dimensions in the health professions and in the hospital setting is stated. It is enhanced that even though the burnout scores were in the average range more than half of the population studied were considering to leave their work in the future.

[Acute effects of inhaled nitric oxide in children]. / Respuesta aguda a la administración de óxido nítrico en niños.

OBJECTIVE: The objective of this study was to analyze the therapeutic response to inhaled nitric oxide (NO) in children with acute respiratory distress syndrome (ARDS) and/or pulmonary hypertension (PHT). PATIENTS AND METHODS: We studied prospectively 25 children, 14 boys and 11 girls, between 15 days and 16 years of age. Seventeen patients were diagnosed with ARDS and 8 with PHT, four of which had secondary ARDS. All patients presented hypoxemia and/or PHT refractory to conventional therapy. We analyzed the PaO2/FiO2 ratio, oxygenation index and mean pulmonary arterial pressure (mPAP)/mean systemic arterial pressure (mSAP) before and after treatment with inhaled nitric oxide. Patients were treated with inhaled NO at 1.5 to 45 ppm between 45 minutes to 47 days. RESULTS: NO improved oxygenation, increasing by greater than 15% the PaO2/FiO2 ratio in 84% of the patients. In those patients which improved, PaO2 increased from 87.4 +/- 57.7 mmHg to 133.6 +/- 60.1 mmHg (p < 0.001), the PaO2/FiO2 ratio from 95.4 +/- 60.9 to 157.5 +/- 86.8 (p < 0.0001) and the oxygenation index diminished from 25.6 +/- 15.6 to 17 +/- 12.4. The PAP/SAP ratio diminished by greater than 15% in 66% of the patients, decreasing from 59.9 +/- 24.5% to 42.6 +/- 14.1% (p = 0.01). CONCLUSIONS: Inhaled NO improved oxygenation and decreased pulmonary hypertension in an important number of children with ARDS and/or PHT.
