BACKGROUND: Eye examinations for retinopathy of prematurity (ROP) are painful to the neonate. The use of topical anesthetic for eye examinations to evaluate ROP is routine in our neonatal intensive care unit (NICU), but does not completely suppress painful responses. Sweet solutions have been shown to reduce procedural pain in newborns.
OBJECTIVE: To examine whether the addition of sucrose 24% to topical anesthetic improves procedural pain control during the ROP eye examination.
METHODS: Neonates born at
30 weeks' gestation were included in
this placebo-controlled, double-blind, crossover study. Patients were randomly
assigned to receive treatment with either proparacaine HCl ophthalmic solution
0.5% plus 2 mL of sucrose 24% or proparacaine HCl ophthalmic solution 0.5%
plus 2 mL of sterile water (placebo) prior to an eye examination. In a
subsequent eye examination, each patient received the alternate treatment.
Oral sucrose and sterile water were prepared in the pharmacy in identical
syringes, and physicians, nurses, and pharmacists in the NICU were blinded to
the treatment given. Pain was measured using the Premature Infant Pain Profile
(PIPP) scoring system, which measures both physical and physiologic measures
of pain, and the scores were simultaneously assessed by 2 study nurses. PIPP
scores were recorded 1 and 5 minutes before and after the eye examination and
during initial placement of the eye speculum. The same ophthalmologist
performed all eye examinations. Several different definitions of a pain
response were investigated.
RESULTS: Twenty-three infants were studied, with 12 receiving sucrose and 11 receiving placebo as the first treatment. For 3 of the 5 definitions of pain response, patients experienced significantly less pain at speculum insertion with sucrose than with placebo. After the ROP examination, pain responses were similar with either sucrose or placebo.
CONCLUSIONS: Oral sucrose may reduce the immediate pain response in premature infants undergoing eye examination for ROP.
