[Starting of a new pediatric palliative care program in a general hospital: characteristics of the population and use of resources].

This article sets out to describe the characteristics of patients at a second-level hospital who are likely to receive pedi-atric palliative care (PPC), the frequency of visits to the emergency room, admissions and technological devices used. A retrospective study was carried out of the patients who received care from the start of the PPC program (January 2017 to January 2020) at a secondary-level hospital. Twenty-nine patients were included, 58.6% male with mean age at entry into the study of 2.3 years (SD: 2.4); 44.8% of them were from rural areas. The prevalence of multimorbidity was 41%, with a higher frequency of neurological patholo-gy. Respiratory infection was the most frequent cause of emergency care (n = 360) and hospitalization (n=145). Half of patients (51.7%) depended on medical devices. Better knowledge of the resources used by this population can lead to more effective distribution/management that in turn can enable PPC to be offered regardless of the place of residence.

OLA strategy for ARDS: Its effect on mortality depends on achieved recruitment (PaO2/FiO2) and mechanical power. Systematic review and meta-analysis with meta-regression.

OBJECTIVE: The "Open Lung Approach" (OLA), that includes high levels of positive end-expiratory pressure coupled with limited tidal volumes, is considered optimal for adult patients with ARDS. However, many previous meta-analyses have shown only marginal benefits of OLA on mortality but with statistical heterogeneity. It is crucial to identify the most likely moderators of this effect. To determine the effect of OLA strategy on mortality of ventilated ARDS patients. We hypothesized that the degree of recruitment achieved in the control group (PaO2/FiO2 ratio on day 3 of ventilation), and the difference in Mechanical Power (MP) or Driving Pressure (DP) between experimental and control groups will be the most likely sources of heterogeneity. DESIGN: A Systematic Review and Meta-analysis was performed according to PRISMA statement and registered in PROSPERO database. We searched only for randomized controlled trials (RCTs). GRADE guidelines were used for rating the quality of evidence. Publication bias was assessed. For the Meta-analysis, we used a Random Effects Model. Sources of heterogeneity were explored with Meta-Regression, using a priori proposed set of possible moderators. For model comparison, Akaike's Information Criterion with the finite sample correction (AICc) was used. SETTING: Not applicable. PATIENTS: Fourteen RCTs were included in the study. INTERVENTIONS: Not applicable. MAIN VARIABLES OF INTEREST: Not applicable. RESULTS: Evidence of publication bias was detected, and quality of evidence was downgraded. Pooled analysis did not show a significant difference in the 28-day mortality between OLA strategy and control groups. Overall risk of bias was low. The analysis detected statistical heterogeneity. The two "best" explicative meta-regression models were those that used control PaO2/FiO2 on day 3 and difference in MP between experimental and control groups. The DP and MP models were highly correlated. CONCLUSIONS: There is no clear benefit of OLA strategy on mortality of ARDS patients, with significant heterogeneity among RCTs. Mortality effect of OLA is mediated by lung recruitment and mechanical power.

[Boussignac continuous positive airway pressure device during inter-hospital transportation in infants aged less than three months]. / Dispositivo de presión positiva continua en la vía aérea de Boussignac durante el transporte interhospitalario en lactantes menores de tres meses.

BACKGROUND: The present study aims to evaluate the safety and effectiveness of the Boussignac continuous positive airway pressure device (CPAPB) when used during the transportation of infants under three months of age with bronchiolitis. METHODS: Transversal analytical observational study of four years duration. Data was collected on 25 infants who needed inter-hospital transportation to the reference Paediatric Intensive Care Unit (PICU), with CPAPB and Helmet interface. The epidemiological characteristics of the transportation and evolution in the PICU were registered, as well as the cardiorespiratory gastronomic parameters prior to transfer and on arrival at the PICU. RESULTS: The median level of continuous airway pressure (CPAP) used during the transfer was 7 cm H2O (6-7.25). No patient required endotracheal intubation during transportation, while one patient required this during the first six hours of admission in the PICU. The following cardiorespiratory parameters presented a statistically significant improvement on arrival at the PICU: modified Wood-Downes score [8.40 (2.1) vs 5.29 (1.68)], respiratory frequency [60.72 (12.73) vs 47.28 (10.31)], cardiac frequency [167.28 (22.60) vs 154.48 (24.83)] and oxygen saturation [92.08 (5.63) vs 97.64 (2.27)]. CONCLUSIONS: Application of CPAPB proved to be a safe method of respiratory support in infants under three months of age. Its use during transportation brought an improvement in cardiorespiratory parameters.
