[Hemodynamic consequences of umbilical arterial catheterization. Photoplethysmographic study].
The hemodynamic consequences of umbilical arterial infusions in newborns can be registered by photoplethysmography. Thirty-nine children were observed according to the same protocol: it was possible to recognize, on the side of the infusion, without other clinical symptoms, very early but after different times: - in 3 cases, the supression of arteriolar oscillations, back to normal after 24 hours in one case, and after several weeks in 2 cases; - in 2 cases, a transitory increase of arteriolar oscillations; - in 7 cases, an elective decrease of the arteriolar systolic pressure, with unchanged diastolic pressure. In 4/7 cases, it became normal in less than 3 days; - in 3 cases, a decrease in arteriolar systolic and diastolic pressures, during 2 days.
