Comparative Study Observational StudyComparison of Tidal Volumes at the Endotracheal Tube and at the Ventilator.
Lung protective ventilation for children with acute respiratory distress syndrome requires accurate assessment of tidal volume. Although modern ventilators compensate for ventilator tubing compliance, tidal volume measured at the ventilator may not be accurate, particularly in small children. Although ventilator-specific proximal flow sensors that measure tidal volume at the endotracheal tube have been developed, there is little information regarding their accuracy. We sought to test the accuracy of ventilator measured tidal volume with and without proximal flow sensors against a calibrated pneumotachometer in children. ⋯ Tidal volume measured either at the endotracheal tube with a proximal flow sensor or at the ventilator with compensation for tubing compliance are both significantly lower than tidal volume measured with a calibrated pneumotachometer. This underestimation of delivered tidal volume may be particularly important when managing children with acute respiratory distress syndrome.

Comparative Study Observational StudyLocation of the Central Venous Catheter Tip With Bedside Ultrasound in Young Children: Can We Eliminate the Need for Chest Radiography?
To compare the use of bedside ultrasound and chest radiography to verify central venous catheter tip positioning. ⋯ Bedside ultrasound showed a good agreement with chest radiography in detecting central venous catheter tip location and revealing incorrect positions. Ultrasound could be a preferable method for routine verification of central venous catheter tip and can contribute to increased patient safety.

Randomized Controlled TrialThe Value of Screening Parents for Their Risk of Developing Psychological Symptoms After PICU: A Feasibility Study Evaluating a Pediatric Intensive Care Follow-Up Clinic.
This study aimed to assess whether prospectively screening parents for psychological vulnerability would enable beneficial targeting of a subsequent follow-up clinic. ⋯ All parents completed Impact of Event Scale-Revised and Hospital Anxiety and Depression Scale at 6 months. Of the 209 parents of 145 children recruited to the study, 78 (37%) were identified, on the basis of their Posttraumatic Adjustment Scale score at baseline, as being at risk of developing posttraumatic stress disorder, and randomized to the control or intervention condition. Follow-up data were provided by 157 of 209 parents (75%). Logistic regression analyses controlling for parent gender and child length of stay showed that high-risk control parents (n = 32) were significantly more likely to score above the clinical cutoff for all three psychological outcomes than parents deemed low risk at baseline (n = 89) (posttraumatic stress: odds ratio = 3.39; 95% CI, 1.28-8.92; p = 0.014; anxiety: odds ratio = 6.34; 95% CI, 2.55-15.76; p < 0.001; depression: odds ratio = 4.13; 95% CI, 1.47-11.61; p = 0.007). Only 14 of 38 (37%) high-risk intervention parents attended the follow-up clinic appointment they were offered. At follow-up, there were no statistically significant differences between the intervention and control groups, but there were small effect sizes in favor of the intervention for anxiety scores (Cohen d = 0.209) and depression scores (Cohen d = 0.254) CONCLUSIONS:: Screening parents for psychological vulnerability using measures such as the Posttraumatic Adjustment Scale may enable more efficient targeting of support. However, further research is needed on how best to provide effective follow-up intervention for families.
