PediTools vs UmbiCalc

Designed for clinicians, this is the most flexible gestational age calculator available, ideal for obstetricians, neonatologists, and pediatricians. Enter any available dates, ages, or gestations, and other values will be calculated. Example use cases: • for obstetricians, enter the date of the last menstrual period, and the due date will be calculated. By default, the current gestational age will also be displayed. • for neonatologists, enter the due date and the date of birth, and the gestation at birth will be calculated. A date of interest can also be entered (defaults to current date), and the age and postmenstrual age will also be displayed. Also, the date of the initial exam for retinopathy of prematurity is shown. • for pediatricians, entering the date of birth, gestational age at birth, and current date will yield the chronologic age and age corrected for prematurity. Ideal for developmental pediatricians to assess milestone acquisition. Feedback appreciated!

This app provides the birth weight-based insertion length estimations for umbilical arterial and venous catheters placed in neonates in the Neonatal Intensive Care Unit. UmbiCalc is based on the algorithm described by Tambasco et al. in “A Novel and Accurate Method for Estimating Umbilical Arterial and Venous Catheter Insertion Length.” Journal of Perinatology 2021. The algorithm was derived from statistical modeling using a representative sample of the current NICU population and validated across a wide range of birth weights. Intended for use by neonatologists, pediatricians, and advanced practice providers for personal educational purposes only. It is not intended for use in clinical practice or the delivery of medical care. Always consult with a healthcare provider for advice concerning your health.
