Indeks Effusion Pleura sebagai Prediktor Sindrom Syok Dengue pada Anak di RSUD Dr. Moewardi Surakarta (Pleural Effusion Index as A Predictor for Dengue Shock Syndrome in Children at Dr. Moewardi Hospital Surakarta).
The extent of plasma effusion in dengue hemorrhagic fever (DHF) can be identified by pleural effusion index (PEI) in the right decubitus chest X photo. The PRI is expected to help predict the course of DHF. This study aimed to estimate the PEI values that can be used to predict dengue shock syndrome (DSS) in children. This was a prospective cohort study conducted in the pediatric ward at Dr. MoewardiHospital in Surakarta from February to March 2009. The study involved 50 study subjects. Complete blood examination, rapid anti-dengue serology test, right decubitus X photo, and PEI, were performed. The cutoff poin was determined by recelver operating characteristic curve (ROC). Sensitivity, specificity, likelihood ratios, positive and negative predictive values, relative rik, and odds ratio were calculated. The data showed DSS pevalence of 30%, and pleural effusion prevalence of 60%. Using the ROC, the cutoff point of>9% resulted in AUC o.7 (CI 95% 0.6 to 0.8, p= 0.002), sensitivity 80% (CI95% 51.9 to 95-4), specificity 60% (CI 95% 42.1 to 96.1) positivelikelihood ratio 3 (CI 95% 1.4 to 2.9)< to 97.1) Te association between PEI>9% and DSS was statisticall significant. Using logistic regression to contro for confounding factors resulted in an OR for PEI > 9% of 6.0 (CI 95% 1.4 to25.2 p+ 0.014) relative to PEI-9%. PEI can be used to predict the occurance of DSS PEI > 9% has higher risk of DSS than PEI= 9%.
