MAC catheter for hemorrhage, transfusion and fluid resuscitation via automated Masterflex pump, and (15) Foley catheter for urine collection. Not depicted in the illustration are the endotracheal tube, splenectomy, or rectal temperature probe. We’d like to acknowledge Mr. Jerry Louis Shelton at Texas A&M University for his assistance in generating the pig illustration in panel 1A. (B) Experimental timeline depicting controlled 30-minute hemorrhage period, followed by 30 minutes of aortic occlusion, a 10-minute balloon wean and 3-hour critical care resuscitation phase. Animals were randomized to 10%, 20% or 30% hemorrhage (by volume), and then randomized to either no aortic occlusion, partial REBOA (p-REBOA) and full REBOA (f-REBOA) intervention groups. Autologous blood re-transfusion and balloon weaning occurred between 65–75 minutes, after which a closed-loop critical care algorithm was initiated to maintain target MAP>65 mmHg for three hours (until time 240 minutes).

    Sampling:

    Article Title: Change in renal blood flow in response to intrarenal pressure alterations induced by ureteroscopy in an in-vivo porcine model.
    Article Snippet: Introduction High irrigation rates are commonly used during ureteroscopy and can increase intrarenal pressure (IRP) substantially.. Concerns have been raised that elevated IRP may diminish renal blood flow (RBF) and perfusion of the kidney.. Our objective was to investigate the real-time changes in RBF while increasing IRP during Ureteroscopy (URS) in an in-vivo porcine model. Methods Four renal units in two porcine subjects were used in this study, three experimental units and one control.

    Article Title: A battery-less wireless implant for the continuous monitoring of vascular pressure, flow rate and temperature.
    Article Snippet: Devices for monitoring blood haemodynamics can guide the perioperative management of patients with cardiovascular disease.. Current technologies for this purpose are constrained by wired connections to external electronics, and wireless alternatives are restricted to monitoring of either blood pressure or blood flow.. Here we report the design aspects and performance parameters of an integrated wireless sensor capable of implantation in the heart or in a blood vessel for simultaneous measurements of pressure, flow rate and temperature in real time.

Not depicted in the illustration are the endotracheal tube, splenectomy, or rectal temperature probe. We’d like to acknowledge Mr. Jerry Louis Shelton at Texas A&M University for his assistance in generating the pig illustration in panel 1A. (B) Experimental timeline depicting controlled 30-minute hemorrhage period, followed by 30 minutes of aortic occlusion, a 10-minute balloon wean and 3-hour critical care resuscitation phase. Animals were randomized to 10%, 20% or 30% hemorrhage (by volume), and then randomized to either no aortic occlusion, partial REBOA (p-REBOA) and full REBOA (f-REBOA) intervention groups. Autologous blood re-transfusion and balloon weaning occurred between 65–75 minutes, after which a closed-loop critical care algorithm was initiated to maintain target MAP>65 mmHg for three hours (until time 240 minutes).
