Resistive Index Value of Superior Mesenteric Artery In Preterm Infants With Necrotizing Enterocolitis

Aims: to find out the comparison of RI values of superior mesenteric artery inpremature infants with NEC and without NEC.Material and methods: This study was an observational analytic study, with acase-control study design, where the sampling method was using consecutive samplingin the NICU Room, Anturium and Radiology Department Dr. Hasan Sadikin GeneralHospital Bandung from September to October 2019. Data processing uses unpairedT-test.Results: The total sample was 22 subjects, consisting of 11 with positive NEC and11 negative NEC, with an average gestational age of 31.36 weeks and an average birthweight of 1490.45 grams. In the positive NEC group, the average RI value was 0.90and in the negative NEC group, the average RI value was 0.70. Statistical test resultswith unpaired T-test showed that there was a statistically significant increase in thevalue of superior mesenteric artery RI in premature infants with NEC compared topremature infants without NEC with a p-value = 0.0001 (p-value < 0.05).Conclusion: There was an increase in the value of superior mesenteric artery RIin premature infants with NEC compared to premature infants without NEC with avalue of p = 0.0001 (p-value <0.05).Key words: Necrotizing Enterocolitis–Superior Mesenteric Artery–Ultrasonography
