Estimation of changes in cyclic lung strain by electrical impedance tomography: Proof of concept study.
Cyclic strain may be a determinant of ventilator-induced lung injury. The standard for strain assessment is the computed tomography (CT), which does not allow continuous monitoring and exposes to radiation. Electrical impedance tomography (EIT) is able to monitor changes in regional lung ventilation. In addition, there is a correlation between mechanical deformation of materials and detectable changes in its electrical impedance, making EIT a potential surrogate for cyclic lung strain measured by CT (StrainCT ). ⋯ The change in electrical impedance may provide a noninvasive assessment of global cyclic strain, without radiation at bedside.

Consensus on predictors of clinical deterioration in emergency departments: a Delphi process study.
The study aim was to determine relevance and applicability of generic predictors of clinical deterioration in emergency departments based on consensus among clinicians. ⋯ The Delphi-process led to consensus of 19 potential predictors of clinical deterioration widely accepted as relevant and applicable in emergency departments.

Observational StudyContinuous peripheral perfusion index in patients admitted to hospital wards - an observational study.
Risk patients admitted to hospital wards may quickly develop haemodynamic deterioration and early recognition has high priority to allow preventive intervention. The peripheral perfusion index (PPI) may be an indicator of circulatory distress by assessing peripheral perfusion non-invasively from photoplethysmography. We aimed to describe the characteristics of PPI in hospitalized patients since this is not well-studied. ⋯ Lower PPI during daytime vs evening and night-time were seen for both populations. The highest frequency of serious adverse events and mortality was seen among patients with low median PPI. The clinical impact of PPI monitoring needs further confirmation.

Clinical TrialThe 90% effective dose of intranasal dexmedetomidine for procedural sedation in children with congenital heart disease before and after surgery: a biased-coin design up-and-down sequential allocation trial.
Intranasal dexmedetomidine can provide adequate sedation during short procedures. However, there are few reports investigating the effective dose of intranasal dexmedetomidine for sedation in children with congenital heart disease (CHD) before and after surgery. ⋯ The 90% effective dose of intranasal dexmedetomidine for sedation in children with CHD was 2.13 μg/kg before cardiac surgery and 3.51 μg/kg after cardiac surgery.
