Predictors of Umbilical Venous Catheter Misalignment

Area of Science:

• Neonatal Medicine
• Pediatric Surgery
• Medical Imaging

Background:

• Umbilical venous catheter (UVC) insertion is a common neonatal procedure.
• Current success rates are suboptimal (40-50%), with complications linked to UVC malposition.
• Predicting UVC alignment is crucial for patient safety and procedural success.

Purpose of the Study:

• To identify factors predicting umbilical venous catheter misalignment.
• To test the hypothesis that chronological age is associated with UVC malalignment.

Main Methods:

• Retrospective chart review of neonates undergoing UVC placement and subsequent X-ray.
• Statistical analysis including logistic regression modeling.
• Sample size of 480 patients.

Main Results:

• Chronological age was a significant positive predictor of UVC misalignment.
• Small for gestational age (SGA) status was a significant negative predictor of UVC misalignment.
• Gestational age and 5-minute APGAR scores showed significant differences between groups.

Conclusions:

• Increased chronological age is associated with a higher likelihood of UVC misalignment.
• Being small for gestational age (SGA) is associated with a higher likelihood of UVC alignment.
• These findings can help predict and potentially prevent UVC malposition in neonates.
