Chest compression duration influences outcome between integrated load-distributing band and manual CPR during cardiac arrest.
The Circulation Improving Resuscitation Care (CIRC) Trial found equivalent survival in adult out-of-hospital cardiac arrest (OHCA) patients who received integrated load-distributing band CPR (iA-CPR) compared to manual CPR (M-CPR). We hypothesized that as chest compression duration increased, iA-CPR provided a survival benefit when compared to M-CPR. ⋯ After adjusting for compression duration and duration-treatment interaction, iA-CPR showed a significant benefit for survival to hospital discharge vs. M-CPR in patients with OHCA if chest compression duration was longer than 16.5 min.

Prediction of postoperative pain from assessment of pain induced by venous cannulation and propofol infusion.
Postoperative pain may lead to delayed mobilization, persisting pain, and psychosocial distress. There are no simple and reliable techniques for prediction of postoperative pain. This study was designed to evaluate if pain induced by venous cannulation or propofol injection can be used to predict postoperative pain. ⋯ Pain intensity associated with venous cannulation and propofol infusion can easily be evaluated at bedside before surgery without specific equipment or training. Patients scoring > 2.0 VAS units on venous cannulation were found to have 3.4 times higher risk of postoperative pain after laparoscopic cholecystectomy. Low pain intensity associated with venous cannulation and propofol infusion indicate lower risk of postoperative pain.

A validation of the pain interference index in adults with long-standing pain.
Chronic pain is a major health problem and more knowledge is needed regarding the interference of pain on behaviors in different life domains. Clinically useful and statistically sound pain interference measures are highly important. Studies on youths have shown that the Pain Interference Index (PII) is a reliable and valid instrument that is sensitive to change following behavioral treatment. This measure may also have utility for adults, but no study has so far evaluated the statistical properties of the PII for long-standing pain in adults. ⋯ The PII is a brief questionnaire with reliable and valid statistical properties to assess pain interference in adults. Other studies support the reliability and validity of PII for use with youths, and now the PII can be used to analyze the influence of pain on behaviors across age groups. Potentially, the PII can also be used as an outcome measure in clinical trials.

Randomized Controlled TrialAgreement between Pleth Variability Index and oesophageal Doppler to predict fluid responsiveness.
Optimisation of stroke volume using oesophageal Doppler is an established technique to guide intraoperative fluid therapy. The method has practical limitations and therefore alternative indices of fluid responsiveness, such as ventilator-induced variation in the pulse oximetric signal (Pleth Variability Index (PVI)) could be considered. We hypothesised that both methods predict fluid responsiveness in a similar way. ⋯ PVI- and Doppler-based stroke volume optimisations agreed poorly, which did not affect the amount of fluid administered. None of the algorithms showed a good ability to predict fluid responsiveness. Our results do not support the fluid responsiveness concept.
