Objective: To analyze the impact of positive end-expiratory pressure (PEEP) changes on intracranial pressure (ICP) dynamics in patients with acute brain injury (ABI)., Design: Observational, prospective and multicenter study (PEEP-PIC study)., Setting: Seventeen intensive care units in Spain., Patients: Neurocritically ill patients who underwent invasive neuromonitorization from November 2017 to June 2018., Interventions: Baseline ventilatory, hemodynamic and neuromonitoring variables were collected immediately before PEEP changes and during the following 30 min., Main Variables of Interest: PEEP and ICP changes., Results: One-hundred and nine patients were included. Mean age was 52.68 (15.34) years, male 71 (65.13%). Traumatic brain injury was the cause of ABI in 54 (49.54%) patients. Length of mechanical ventilation was 16.52 (9.23) days. In-hospital mortality was 21.1%. PEEP increases (mean 6.24-9.10 cmH2O) resulted in ICP increase from 10.4 to 11.39 mmHg, P < .001, without changes in cerebral perfusion pressure (CPP) (P = .548). PEEP decreases (mean 8.96 to 6.53 cmH2O) resulted in ICP decrease from 10.5 to 9.62 mmHg (P = .052), without changes in CPP (P = .762). Significant correlations were established between the increase of ICP and the delta PEEP (R = 0.28, P < .001), delta driving pressure (R = 0.15, P = .038) and delta compliance (R = -0.14, P = .052). ICP increment was higher in patients with lower baseline ICP., Conclusions: PEEP changes were not associated with clinically relevant modifications in ICP values in ABI patients. The magnitude of the change in ICP after PEEP increase was correlated with the delta of PEEP, the delta driving pressure and the delta compliance., (Copyright © 2024 Elsevier España, S.L.U. and SEMICYUC.

SARS-CoV-2 infection has had a major impact on donation and transplantation. Since the cessation of activity two years ago, the international medical community has rapidly generated evidence capable of sustaining and increasing this neccesary activity. This paper analyses the epidemiology and burden of COVID-19 in donation and transplantation, the pathogenesis of the infection and its relationship with graft-mediated transmission, the impact of vaccination on donation and transplantation, the evolution of donation in Spain throughout the pandemic, some lessons learned in SARS-CoV-2 infected donor recipients with positive PCR and the applicability of the main therapeutic tools recently approved for treatment among transplant recipients., (©The Author 2022.

Objetive: To perform a score with early clinical and radiological findings after a TBI that identifies the patients who in their subsequent evolution are going to undergo DC., Method: Observational study of a retrospective cohort of patients who, after a TBI, enter the Neurocritical Section of the Intensive Care Unit of our hospital for a period of 5 years (2014-2018). Detection of clinical and radiological criteria and generation of all possible models with significant, clinically relevant and easy to detect early variables. Selection of the one with the lowest Bayesian Information Criterion and Akaike Information Criterion values for the creation of the score. Calibration and internal validation of the score using the Hosmer-Lemeshow and a bootstrapping analysis with 1000 re-samples respectively., Results: 37 DC were performed in 153 patients who were admitted after a TBI. The resulting final model included Cerebral Midline Deviation, GCS and Ventricular Collapse with an Area under ROC Curve: 0.84 (95% IC 0.78-0.91) and Hosmer-Lemeshow p=0.71. The developed score detected well those patients who were going to need an early DC (first 24h) after a TBI (2.5±0.5) but not those who would need it in a later stage of their disease (1.7±0.8). However, it seems to advice us about the patients who, although not requiring an early DC are likely to need it later in their evolution (DC after 24h vs. do not require DC, 1.7±0.8 vs. 1±0.7; p=0.002)., Conclusion: We have developed a prognostic score using early clinical-radiological criteria that, in our environment, detects with good sensitivity and specificity those patients who, after a TBI, will require a DC., (Copyright © 2020 Sociedad Española de Neurocirugía.

Normothermic regional perfusion (NRP) in controlled donation after circulatory death is becoming a popular method due to the favorable results of the grafts procured under this technique. This procedure requires experience, and, sometimes, the availability of extracorporeal membrane oxygenation (ECMO) machines to implement NRP is limited to tertiary hospitals. In order to provide support with NRP in controlled donation after circulatory death across the different hospitals of the Autonomous Community of Madrid, a mobile NRP team was created. In the first 18 months since its creation, the mobile NRP team participated in 33 procurements across nine different hospitals, representing 72% of all controlled donations after circulatory death in the Autonomous Community of Madrid. NRP was successfully performed in 29 (88%) cases, with a mean duration of 69 ± 27 minutes. A total of 39 kidneys, 12 livers, and 5 bilateral lungs were recovered and transplanted. None of the livers were discarded due to an elevation in transaminases during NRP. A mobile NRP team is a feasible option and, in our series, aided in the optimization and recovery of organs from donors after controlled circulatory death in centers where ECMO technology was not available., (© 2020 John Wiley & Sons A/S.

Objective: To know the real clinical practice of Spanish ICUs in relation to analgesia, sedation and delirium, with a view to assessing adherence to current recommendations., Design: A descriptive cross-sectional study was carried out based on a national survey on analgesia, sedation and delirium practices in patients admitted to intensive care on 16 November, 2013 and 16 October, 2014. An on-line questionnaire was sent with the endorsement of the SEMICYUC., Setting: Spanish ICUs in public and private hospitals., Results: A total of 166 ICUs participated, with the inclusion of 1567 patients. The results showed that 61.4% of the ICUs had a sedation protocol, and 75% regularly monitored sedation and agitation - the RASS being the most frequently used scale. Pain was monitored in about half of the ICUs, but the behavioral scales were very little used. Delirium monitoring was implemented in few ICUs. Among the patients on mechanical ventilation, midazolam remained a very commonly used agent., Conclusions: This survey is the first conducted in Spain on the practices of analgesia, sedation and delirium. We identified specific targets for quality improvement, particularly concerning the management of sedation and the assessment of delirium., (Copyright © 2018 Elsevier España, S.L.U. y SEMICYUC.
