In severely injured trauma patients, hypofibrinoginaemia is associated with increased mortality. There is no evidence-based consensus for what constitutes optimal fibrinogen therapy, treatment dose or timing of administration. The aim of this systematic review was to evaluate the effects of early fibrinogen replacement, either cryoprecipitate or fibrinogen concentrate (FgC) on mortality, transfusion requirements and deep venous thrombosis (DVT). ⋯ There is no association between early fibrinogen replacement and mortality, DVT or transfusion requirements. We found no superiority between FgC or cryoprecipitate. This systematic review highlights the urgent need for further RCTs to assess the efficacy of early fibrinogen replacement, preferred strategy (goal-directed vs empiric) as well as optimal therapeutic product for both patient outcome and cost effectiveness.

Meta Analysis
Individualized PEEP titration by lung compliance during one-lung ventilation: a meta-analysis.
Despite the physiological advantages of positive end-expiratory pressure (PEEP), its optimal utilization during one-lung ventilation (OLV) remains uncertain. We aimed to investigate whether individualized PEEP titration by lung compliance is associated with a reduced risk of postoperative pulmonary complications during OLV. ⋯ Compared with fixed PEEP, individualized PEEP titration by lung compliance is associated with a reduced risk of postoperative pulmonary complications during OLV, especially in PEEP titration by dynamic compliance or stepwise decremental strategy. It improves respiratory mechanics and oxygenation with no difference in hemodynamic variables. Trial registration number ClinicalTrials.gov (PROSPERO No. CRD42024529980).

Pulse pressure variation (PPV) is limited in low tidal volume mechanical ventilation. We conducted this systematic review and meta-analysis to evaluate whether passive leg raising (PLR)-induced changes in PPV can reliably predict preload/fluid responsiveness in mechanically ventilated patients with low tidal volume in the intensive care unit. ⋯ PLR-induced change in absolute PPV has good diagnostic performance in predicting preload/fluid responsiveness in ICU patients on mechanical ventilation with low tidal volume. Trial registration PROSPERO (CRD42024496901). Registered on 15 January 2024.
