The purpose of this study was to determine the incidence, severity, contributing risk factors associated with vasopressin-induced hyponatremia in neonates and infants &amp;lt;3 months of age in the NICU. The primary objective was to determine the incidence of hyponatremia (&amp;lt;130\u2005mEq\/L) and severe hyponatremia (&amp;lt;125\u2005mEq\/L). The secondary objectives were to compare clinical characteristics and the vasopressin regimen between those with and without hyponatremia.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      This retrospective cohort study included neonates and infants &amp;lt;3 months from 1\/1\/2017\u201312\/31\/2022 receiving vasopressin for &amp;gt;6\u2005h.

Overall, the median (interquartile range, IQR) gestational and postnatal age at vasopressin initiation were 35.4 (27\u201338.7) weeks and 2 (1\u201312) days. There was no difference in vasopressin dose, but duration of treatment was longer in those with hyponatremia. Higher baseline serum sodium was associated with decreased odds of hyponatremia [adjusted odds ratio (OR): 0.90 (95% CI: 0.83\u20130.99),\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.03], and increased vasopressin duration was associated with increased odds of hyponatremia [aOR: 1.02 (95% CI: 1.01\u20131.03),\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&amp;lt;\u20090.001].\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Hyponatremia occurred in half of patients included.
