Aims:
To evaluate the usefulness of intravesical pressure as a prognostic indicator in congenital diaphragmatic hernia.
Material And Methods:
In 25 cases, bladder pressure was measured intraoperatively during repair.
Results:
Cases were divided into three groups according to the intravesical pressure. Group 1: pressure <10 cm (n.9), Group 2: 10-15 cm (n.11) and Group 3: >15 cm (n.5). Number of ventilated days was tabulated against these groups. Median number of ventilated days for Group 1, with the lowest pressure, was 3 days, while that for Group 2 was 5 and for Group 3, with the highest pressure, was 10 days. This was significant, with a P-value of 0.016.
Conclusion:
Measurement of intravesical pressure is a reliable prognostic indicator in newborns with congenital diaphragmatic hernia. It also helps in predicting postoperative ventilatory requirement.
