Effect of mydriatics on blood pressure in premature infants.

Abstract

Systolic blood pressure (SBP) was measured by doppler methods at 5, 15, 30, 45, and 60 minutes in 52 premature infants after triple instillation of aqueous phenylephrine 2.5% and tropicamide 1.0%. Systolic blood pressures were insignificantly increased 3.9 +/- 2.0 mm Hg (mean +/- S.E.) at 15 minutes when compared with controls matched for initial blood… (More)
