Effect of Benoxinate Hydrochloride Eye Drops on The Premature Infant Pain Profile Score During Retinopathy of Prematurity Screening
- Conditions
- Retinopathy of Prematurity
- Interventions
- Drug: Benoxinate HydrochlorideDrug: artificial tear (Sodium Hyaluronate 2 mg/ml) eye drops.
- Registration Number
- NCT06461975
- Lead Sponsor
- Alexandria University
- Brief Summary
Aims: To evaluate the effects of topical Benoxinate HCL eye drops on the Premature Infant Pain Profile (PIPP) scores in infants undergoing Retinopathy of Prematurity (ROP) screening.
Methods: A randomized prospective double-masked cross-over trial was conducted on preterm infants screened for ROP at least twice. Dilated fundus examination was done in Group A infants using the tear substitute eye drops and the second using the Benoxinate HCL drops and the reversed order of drops for Group B. Video recording of the pulse oximeter monitor, the face and the body of the infant were analyzed by a single neonatology consultant for Premature Infant Pain Profile (PIPP) scoring 1 minute before, during the examination of the first eye, 1 minute and 5 minutes after the conclusion of the examination of the second eye. The sound of the ophthalmologist on the video recordings indicating the time of the lid speculum insertion, the shining of the indirect ophthalmoscope light without indentation and the scleral indentation would aid in assessing the differences of the PIPP indicators during each step of the examination.

Group Intervention Description Benoxinate HCL in first exam Benoxinate Hydrochloride infants in Group B had the reversed order of the drops in the two examinations. the first examination done using the Benoxinate HCL drops and the second using the tear substitute eye drops Tear substitute in first exam artificial tear (Sodium Hyaluronate 2 mg/ml) eye drops. Te first examination was done using the tear substitute eye drops and the second using the Benoxinate HCL drops given just before the ROP screening.
- Primary Outcome Measures
Name Time Method PIPP score 1-3 month after birth The PIPP is a composite measure that includes seven indicators, each of which is rated on a four-point scale (0-3). The indicators include heart rate, oxygen saturation, GA, brow bulge, nasolabial furrow, behavioural state, and eye squeeze. Larger number indicates more stress (worse outcome)
