Efficacy of Mydriatic Drops in Premature Infants
Study Details
Study Description
Brief Summary
Because of the neonatologists reported that some infants had suffered from vomiting, bradycardia, hypotonia, and aspiration risk about 30-60 minutes after the fundus examination in the intensive care unit. The investigators observed the pupil dilation effects and side effects of tipple instillation of phenylephrine 2.5% plus tropicamide 0.5% ophthalmic drop combination which the investigators routinely used in ROP examination.

Detailed Description
Purpose: To determine effect and vital change after topical application of phenylephrine 2.5% and tropicamide 0.5% three times for retinopathy of prematurity (ROP) examination in preterm infants.
Methods: Pupillary diameter, blood pressure, pulse rate, and oxygen saturation were monitored before, and after up to 24 hours 60 ROP screening examinations.
