INTRODUCTION: There are various techniques for assessing the uid status such as clinical examination, central venous pressure (CVP) measurement, biochemical markers, bio impedance, continuous blood volume measurement, or sonographic inferior vena cava (IVC) diameter assessment. Sonographic evaluation of the IVC and Aorta diameter and its usefulness in evaluating the volume status are studied and documented. The sonographic evaluation of the IVC & Aorta can predict the volume status, this tool can assist anesthetist in rapid diagnosis and prompt resuscitation of patients developing TURP syndrome AIM OF THE STUDY: The aim & objective of this study is to assess the correlation of Caval Aorta index with CVP in intravascular volume assessment in patients undergoing endoscopic Trans Urethral Resection of Prostate (TURP) MATERIALS AND METHODS: The study is carried out in the Department of Anaesthesiology involving Department of Urology in Kanyakumari Government Medical College from January 2018 to June 2019. It is a Prospective observational study. To measure the IVC diameter USG machine probe is placed in the sub-xiphoid region to visualize the conuence of the hepatic veins draining the IVC. The maximum internal AP diameter of the Aorta(Ao) and maximum internal anterior-posterior (AP) diameter of the IVC is measured in the longitudinal plane. Fluid status will be measured by CVP and IVC/Ao index recorded before neuraxial block, after preload, at 5 min after intrathecal block, resection time at 0 min, every 15 min during the rst 30 min, then every 30 min, until the end of surgery. Outcome: Incidence of hypotension after spinal anesthesia in a cesarean section RESULTS: The mean IVC diameter at pre-operative is 15.20±1.42, and at 60 min, 75 min were 19.39±1.92, 20.03±1.76 which suggests that the size and shape of the inferior vena cava (IVC) is correlated to the CVP and circulating blood volume. In my study the mean Aortic diameter at 60 min, 75 min were 20.30±1.01 and 19.81±1.06 which is same as the preoperative level (19.72±1.18) and diameter. The mean CVP at pre-operative is 4.57±0.73, mean CVP at 60 min, 75 min were 7.57±0.82, 8.11±0.78 which denotes that CVP increases as the intravascular volume status increases. In our study mean IVC/Aortic index at pre-operative is 0.77±0.05 and the mean IVC/Aortic index at 15min, 30 min, 60 min, 75 min were 0.87±0.03, 0.90±0.04, 0.95±0.06, 1.01±0.05 which increases signicantly in increasing intravascular volume. The strong correlation between these two variable with Pearson formula ranging from 0.450-0.900. CONCLUSION: As Sonographic caval Ao index is very well correlated with CVP , IVC/Ao index is useful for the evaluation of preoperative and intraoperative volume status, especially in major surgeries with marked uid shift or blood loss and had the advantage of being noninvasive, safe, quick, and easy technique with no complications.

Collapsibility Index

Introduction: Accurate assessment of relative intravascular volume is needed to guide management of acute decompensated heart failure (ADHF). Current assessments include history and physical examination (specific but not sensitive), and N-terminal prohormone of brain natriuretic peptide (NT-proBNP) (sensitive but not specific).Ultrasound (US) of inferior vena cava (IVC) collapsibility with respiration is commonly used to assess intravascular volume and right atrial pressure (RAP) but may be technically challenging. US of subclavian vein (SCV) collapsibility may provide an alternative assessment. Hypothesis: In ADHF, SCV collapsibility index (CI) may correlate with IVC CI and RAP. Methods: Prospective study of non-ventilated patients with ADHF who had NT-proBNP within 24 hours of paired IVC and SCV diameter measurements by US. Results: Forty-two patients (median age 66.5 years, 45% female, and 64% white) were enrolled, with 52 encounters. Cardiovascular comorbidities included hypertension (93%), chronic kidney disease (64%), coronary artery disease (55%), atrial fibrillation/flutter (55%), and valvular disease (55%). Of 38 patients with known heart failure, 63% had HFrEF, 16% HFmrEF, and 21% HFpEF.Correlation of paired IVC CI and SCV CI with relaxed breathing was R = 0.65 (N = 36). Correlation of paired IVC CI and SCV CI with forced inhalation was R = 0.47 (N = 36). Log 10 NT-proBNP was inversely correlated with IVC CI (R = -0.35; N = 51) and SCV CI (R = -0.33; N = 36). For patients with right heart catheterization within 24 hours of US, correlation of RAP to IVC CI was R = -0.53 (N = 9), and RAP to SCV CI was R = -0.65 (N = 9). Moderate or severe tricuspid regurgitation decreased CI independently of intravascular volume and RAP (figure). Conclusions: US measurements of SCV CI correlate well with paired IVC CI in non-ventilated ADHF. RAP by RHC correlated better with SCV CI than with IVC CI. SCV CI may be a reliable alternative to IVC CI in assessing relative intravascular volume.
