title: [The evaluation of cuff-occluded rate of rise of peripheral venous pressure (CORRP) for monitoring blood volume status].
abstract: Cuff-occluded rate of rise of peripheral venous pressure (CORRP) was evaluated for perioperative monitoring. We investigated the CORRP in 6 patients undergoing open laparotomy. These patients were given general anesthesia, and monitoring lines were inserted. Heart rate, blood pressure (BP), right atrial pressure (RAP), pulmonary capillary wedge pressure (PCWP), pulmonary artery pressure (PAP), cardiac output (CO) and CORRP were monitored. CORRP is defined as the average rate (in millimeters of mercury per minute) of rise of peripheral venous pressure after proximal occlusion of that vein by a tourniquet (select pressure: 50 mmHg). In the actual measurement of CORRP, only the first 90% of the curve after occlusion of the tourniquet is used. CORRP correlated with RAP (r = 0.69 +/- 0.10), and PCWP (r = 0.79 +/- 0.07). On the other hand, there was no significant correlation between CORRP and BP, or PAP and CO. Snyder et al. described that CORRP seems to be an excellent indicator of acute volume change in the hyper- and hypovolemic canine model. We conclude that in these laparotomy patients, CORRP appears to be a sensitive and minimally invasive method of assessing volume status.
