Humans are able to compensate for low-volume blood loss with minimal change in traditional vital signs. We hypothesized that a novel algorithm, which analyzes photoplethysmogram (PPG) wave forms to continuously estimate compensatory reserve would provide greater sensitivity and specificity to detect low-volume blood loss compared with traditional vital signs. The ...

Abstract Introduction and Objectives: Radical prostatectomy (RP) is associated with a high risk of intraoperative blood loss and subsequent blood transfusions. The shift in surgical technique from open radical prostatectomy (ORP) to robot-assisted radical prostatectomy (RARP) has resulted in lower operative blood loss, and reduced the need for transfusions. We ...

Tranexamic acid (TXA) has proven to be very advantageous to the total knee arthroplasty (TKA) population. With TXA, the need for allogeneic blood transfusion is reduced and thus hospital costs are reduced. In our hospital system, before TXA was used, facility cost was an estimated $84.90/TKA for blood transfusion and ...

Clot lysis values (LY30) determined by rapid thrombelastography (rTEG) predict postinjury transfusion needs and mortality risk. However, the first derivative velocity curve values generated by rTEG measuring lysis-maximum rate of lysis (MRL) and total lysis (TL)-have not been evaluated. Although recent data support use of antifibrinolytics in trauma, the population ...

Neurosurgery may involve significant blood loss and frequently requires allogeneic red blood cell (RBC) transfusion. Preoperative recombinant erythropoietin (EPO) may be used to improve erythroid status and recovery, and used either alone or in combination with preoperative autologous donation (PAD) it may reduce exposure to allogeneic RBC. We wished to ...

Rationale: Transfusion of erythrocytes stored for prolonged periods is associated with increased mortality. Erythrocytes undergo hemolysis during storage and after transfusion. Plasma hemoglobin scavenges endogenous nitric oxide leading to systemic and pulmonary vasoconstriction. Objectives: We hypothesized that transfusion of autologous blood stored for 40-days would increase the pulmonary artery pressure ...

Cerebrovascular events contribute to ~40% of preeclampsia/eclampsia-related deaths, and neurological symptoms are common among preeclamptic patients. We previously reported that placental ischemia, induced by reducing utero-placental perfusion pressure, leads to impaired myogenic reactivity and cerebral edema in the pregnant rat. Whether the impaired myogenic reactivity is associated with altered cerebral ...

Blood is a valuable resource, but most people do not donate. One deterrent to blood donation is the anticipation of vasovagal symptoms (e.g., dizziness, nausea, and fainting), despite the fact that such symptoms typically affect a small proportion of donors. The current research examined norm perceptions regarding vasovagal symptom experiences ...

ABSTRACT. Significant drops in arterial blood pressure and cerebral hemodynamics have been previously observed during vasovagal syncope (VVS). Continuous and simultaneous monitoring of these physiological variables during VVS is rare, but critical for determining which variable is the most sensitive parameter to predict VVS. The present study used a novel ...
