Multicenter Study Observational StudyThoracic Paravertebral Nerve Blocks in Pediatric Patients: Safety and Clinical Experience.
Thoracic paravertebral nerve blocks (PVNBs) provide excellent analgesia for many surgeries. The primary aim was to estimate the complication rate, and secondary aims were to provide information on the potential clinical application of PVNBs. Data on 2390 PVNBs were collected. ⋯ There was 1 case of local anesthetic systemic toxicity for a major complication rate of 1 per 2390 PVNBs. The minor complication rate was 13.2%. We demonstrate a low risk of complications in pediatric patients receiving PVNBs for various surgeries.

Comparative Study Observational StudyComparison of SEER Sonorheometry With Rotational Thromboelastometry and Laboratory Parameters in Cardiac Surgery.
The Quantra Hemostasis Analyzer is a novel diagnostic device that uses an ultrasound-based technology, sonic estimation of elasticity via resonance (SEER) sonorheometry, to characterize the dynamic changes in viscoelastic properties of a blood sample during coagulation. Cardiac surgery utilizing cardiopulmonary bypass (CPB) is associated with a significant impact on the coagulation system and can result in perioperative coagulopathy. The aim of this study was to correlate SEER sonorheometry results to corresponding rotational thromboelastometry (ROTEM) and laboratory parameters obtained before, during, and after CPB. ⋯ SEER sonorheometry demonstrates significant correlation with ROTEM for determining Clot Stiffness and assessing Fibrinogen Contribution. SEER sonorheometry results can provide valuable information about the coagulation status in patients undergoing cardiac surgery using CPB.
