About

In this study, the investigators aimed to evaluate the incidence of vena cava inferior diamater on ultrasound guidance of intravascular volume before diagnosis of contrast

• enhanced CT for diagnostic purposes in ileus patients and to investigate the incidence and risk of developing contrast nephropathy due to contrast - enhanced CT.

Full description

Our work will be carried out in Kocaeli Derince Education and Research Hospital Emergency Service. Patients who are scheduled to receive abdominal contrast computed tomography (CT) scans in the emergency room, who are over 18 years of age, who are referred to Kocaeli Derince Education and Research Hospital Emergency Department for the study, will be calculated and recorded. The Mehran risk scores will be calculated and recorded in our clinic. 3 ml / kg IV physiological saline (SF) is applied first and then 1 ml / kg / hr IV SF is applied for at least 6 hours after shots. In addition, patients with contrasted abdominal CT underwent emergency surveillance ultrasound imaging (including the measurement of the vena cava diameter for evaluation of the patient's volume status). Patients who were admitted to our general surgery and not followed up for at least 48 hours, patients with contrast allergies, patients with renal replacement therapy, pregnancies, patients with contrast-enhanced CT scans within the last 10 days, and patients not informed will not be taken to the study. All Emergency Physicians will be informed about the study. Less than 100 mL of hypoosmolar, non-ionic contrast material will be used for all CT shots. Patients will be evaluated for the development of contrast nephropathy according to biochemical assays 48-72 hours after CT acquisition. Physicians evaluating patients in the emergency and general surgery services will be required to record blood tests that they consider necessary for diagnostic and therapeutic purposes, and no extra blood will be collected for use in the study.
