Relationship of passive legs raising with inferior vena cava distensibility index in children with shock

Background: Shock is a clinical syndrome resulting from the body's circulatory system failure, which requires fluid administration and/or vasopressors. Passive leg raising (PLR) examination and inferior vena cava distensibility index (IVCDI) examination are necessary to determine the need for fluid resuscitation in children with shock. The relationship between PLR and IVCDI in children with shock is very important to research. This study aims to find out the relationship between PLR and IVCDI in children with shock. Methods: This research was a quasi -experimental study and employed one group pre-test post-test design. The research subjects were children aged 5 - 18 years with a diagnosis of shock in the PICU of Dr. Moewardi Hospital from June 2022 to July 2022. Data were analyzed using SPSS version 25.0 for Windows. Results: There were 12 children who experienced shock; 9 patients had a positive fluid responsiveness (FR), and 3 patients had a negative FR. In the positive FR group, there was a significant decrease in IVCDI (-50.15 +/- 37.34, p=0.008). In the negative FR group, there was an increase in IVCDI (2.50 +/- 5.55, p = 0.517), although it was not significant. Conclusion: There is a relationship between PLR and IVCDI in pediatric patients with shock
