Minimally Invasive Beaded Electrosurgical Dissectors, Basic Science, and Pilot Studies.

Background: Minimally invasive beaded electrosurgical dissectors ("BEED devices") provide simultaneous sharp dissection, blunt dissection, and electrosurgical coagulation while performing 100 cm porcine tissue plane dissections in 0.8 to 3 min with minimal bleeding and no perforations.

Objectives: The aim of the study was to report the basic science and potential clinical applications and to video document the speed and quality of planar dissections in in vivo and ex vivo porcine models with thermal damage quantified by thermal and histopathologic measurements.

Evaluation of oscillometric and Doppler ultrasonic methods of indirect blood pressure estimation in conscious dogs.

To assess the accuracy and precision of indirect measurements of systemic arterial blood pressure (BP), results obtained with an oscillometric device (BPo) and a Doppler ultrasonic device (BPud) were compared with those obtained by direct radiotelemetry (BPrt) in 12 conscious beagles. The correlation between indirectly obtained and directly measured values for BP parameters ranged widely for the different indirect methods and sites of cuff placement, with R2 between 0.001 and 0.
