POC devices are moderately accurate at detecting renal impairment in patients undergoing radiological investigations. The POC devices did not miss any high-risk patients but underreported eGFR values in certain patients. iSTAT had a R 2 value of 0.83 and coefficient variation of 7.36%. ![]() Statistical analysis revealed that the StatSensor R 2 value was 0.77, and coefficient variation was 10.65%. One hundred one patients underwent the Abbott iSTAT analysis, 139 patients underwent Nova StatSensor analysis, and 53 had both. One hundred eighty-six patients were included in the study. eGFR values were stratified as high risk (eGFR < 30), moderate risk (eGFR 30-59) and low risk (eGFR ≥ 60). Lightweight, portable and easy to use, the i-STAT 1 blood analyzer operates with the advanced technology of i-STAT test cartridges. Renal function was calculated using eGFR via the CKD-EPI result. i-STAT 1 A handheld blood analyzer that delivers lab-quality, diagnostic results in minutes. The two values were analysed and compared. Patients undergoing routine radiological investigations had blood collected and analysed by a POC method and the laboratory method (Beckman AU5800). Two POC devices were evaluated, the Nova StatSensor and Abbott iSTAT. Point of care (POC) devices offer a quick estimation of renal function, potentially improving workflows in radiology departments. One of the biggest risk factors for developing PC-AKI is the presence of pre-existing renal dysfunction, making it important to measure the renal function prior to contrast administration. There exists a small risk of post-contrast acute kidney injury in patients receiving IV contrast. In the perioperative setting, point-of-care INR testing in children using the i-STAT® device is a reliable and easy-to-handle method for INR values ≤2.0, while INR values >2.0 might be underestimated.Intravenous iodinated contrast is a commonly used diagnostic aid to improve image quality on computed tomography. The correlation coefficient was 0.83 (P 2.0, respectively. Reference laboratory INR ranged from 0.96 to 3.43 (mean 1.40 sd 0.32) and INR of i-STAT® from 0.95 to 2.29 (mean 1.26 sd 0.22).

Blood samples for both tests were withdrawn at the same time and immediately analyzed with both devices.Ī total of 169 paired blood samples were taken intraoperatively from 44 pediatric patients. In order to provide the correct contact point, please answer a few questions to help us understand who you are and how best to help you. A volume of 1.4 ml citrated blood was used for the reference laboratory INR test, and 0.1 ml of blood was taken for the whole blood INR test using the i-STAT® device. Blood samples for coagulation testing were tested at several intraoperative time points and generally withdrawn from the arterial catheter, if accessible. Pediatric patients undergoing craniofacial, spine, hip, or cancer surgery were included. The aim of the study was to compare international normalized ratio (INR) results obtained by point-of-care testing (i-STAT® device) with the reference laboratory INR in children undergoing major surgery with expected significant blood loss. ![]()
