    The aim of the study was to evaluate the timing of delivery and the relationship between pathological Doppler ultrasonography and NST in IUGR fetuses. The prospective study included 84 fetuses with ultrasound diagnosis of IUGR and 100 fetuses of normal pregnancy The study group underwent Doppler velocimetry study of UA, MCA, DV and UV twice weekly, AFI twice weekly and NST daily. Apgar score, need of intubation, RDS, IVH, days of NICU hospitalization were available and related to neonatal outcome. Patients were stratified into groups: Preeclampsia with IUGR (Group 1) and IUGR only (group 2). In the group 1 the stillbirth was 3/44 (6,8%), in the group 2 the stillbirth was 8/40 (20%). Sensitivity for NST was 60%, and for Doppler velocimetry of DV was 71%. Specificity for NST was 87%, and for Doppler velocimetry of DV was 90%, respectively. Doppler changes occur first in chronic hypoxia while abnormal NST represent late stage of fetal compromise.

    Assessing Blood pressure using a doppler ultrasound01:19

    Assessing Blood pressure using a doppler ultrasound

    To obtain accurate blood pressure measurements in clinical settings, especially when traditional methods are insufficient, healthcare professionals utilize the Doppler ultrasound technique. This method uses high-frequency sound waves to detect blood flow within the arteries, which is crucial for patients with conditions that complicate circulatory system assessment.

    Aortic Regurgitation II: Clinical Features and Diagnostic Tests01:22

    Aortic Regurgitation II: Clinical Features and Diagnostic Tests

    Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

    Urodynamic Studies: Uroflowmetry

    Uroflowmetry is a non-invasive urodynamic test designed to measure various aspects of urination, including volume, flow rate, and the time to void. This test is crucial for diagnosing and assessing conditions such as bladder outlet obstruction, bladder dysfunction, incomplete bladder emptying, incontinence, and urinary tract blockages caused by benign prostatic hyperplasia (BPH) and urethral strictures.Pre-Test Instructions:Before a uroflowmetry test, patients are typically advised to drink...

    Mitral Regurgitation II: Clinical Features and Diagnostic Tests

    Mitral regurgitation (MR) is a valvular heart disorder in which the mitral valve fails to close tightly, allowing blood to leak backward into the heart. Understanding the clinical manifestations, assessment, diagnostic findings, and medical management of MR is crucial to effectively managing affected patients.Clinical Manifestations of Mitral RegurgitationMitral regurgitation can be acute or chronic, each presenting differently and requiring different approaches:1. Acute Mitral...

    Mitral Stenosis II: Clinical features and Diagnostic Tests

    Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...
