BackgroundMicrocirculatory derangement is the primary cause of organ dysfunction in patients with sepsis. Assessment of the microcirculation is usually done by means of indirect parameters (SvO2 transcutaneous PO2 serum lactate.) The aim of our study is to understand microcirculatory abnormalities in patients with sepsis by directly visualizing the tiny vessels using hand-held video microscopes (HVMs) and determining the role of this modality in the prediction of sepsis-related mortality.MethodsA longitudinal prospective hospital-based study was carried out in medical ward and ICU of a tertiary care hospital. Patients admitted with the presumed infectious disease were included. Evaluation of sublingual microcirculation was done in these patients from Day 1 to Day 5 Clinical and laboratory variables and microcirculation variables were compared between patients with or without sepsis and between survivors and non-survivors of sepsis. Chi-square test for categorical and Student's t-test or Wilcoxon rank-sum test for continuous variables were applied. Univariate and multivariate regression analyses were performed using the Cox-proportional hazard model.Results and discussionOn admission, microcirculation assessment measure, PPV (small), was significantly reduced in those with sepsis, as compared to those without sepsis. Multivariable models indicate the inverse relationship of PPV small with mortality.How to cite this articlePanda A, Revadi G, Sharma JP, Pakhare A, Singhai A, Joshi R, et al.
