Some common hemodynamic disorders and risk factors in patients after Blalock- Taussig Shunt in Vietnam National Children’s Hospital in 2021

Tóm tắt

The aims of this study were to describe some common hemodynamic disorders and evaluate some risk factors in patients after Blalock-Taussig Shunt (BTS).  It was a cross-sectional study in 70 patients less than 5kg with a closed heart surgery by the simple BTS. Patients’ hemodynamic data were collected, some early hemodynamic disorders such as under shunt, over shunt, and capillary leak were described within 48 hours after the BTS, and related factors were recorded. Hemodynamic data were described and compared between complication groups and then some risk factors related to hemodynamic disorders were described. The rate of hemodynamic disorders within 48 hours after the BTS were 94.0%, in which 37.1% were under shunt, 42.9% were overshunt, and 54.3% had capillary leak. Patients with capillary leak after the BTS had higher cardiovascular indexes than those of the others. Neonatal patients and patients who were operated by midline incision had higher risk of capillary leak than the others. BTS patients had a high rate of hemodynamic disorders within 48 hours after the BTS. The neonatal age and the midline incision were risk factors relating to the capillary leak status after the BTS.
