The Effect of Anesthetic Eye Drop Instillation on the Distribution of Corneal Thickness
2012
PURPOSE To address the effect of topical instillation of oxybuprocaine on the relative distribution of corneal thickness (CT) in young healthy subjects. METHODS Prospective study involving 30 eyes of 30 emmetropic subjects (24 ± 3 years). Corneal thickness measurements were carried out before and 3 minutes after the instillation of oxybuprocaine 4% using slit-scanning corneal topography (Orbscan topography system II). No acoustic correction factor was applied. The mean of 5 consecutive Orbscan measurements was obtained at the center and 3 mm from the visual axis in the temporal, superior, nasal, and inferior hemimeridians. RESULTS No significant mean differences were found at any corneal lo…
Comparation of the eutectic mixture of lidocaine/prilocain versus benzocaine gel in children
2011
Objective: To compare the anesthetic effect of a non commercial eutectic mixture of 4% lidocaine/ prilocaine (PLO 4%) and 20% benzocaine gel (Hur- ricaine®), as topical anesthetic, prior to inferior al- veolar nerve block and buccal infiltration anesthesia in 5 - 12 year old children. Study design: Infiltrative anesthesia was applied in 50 children, divided in two groups (n = 25) using PLO 4% and Hurricaine® as topical anesthesia prior to infiltration. Physical reac- tions were registered using the Sound-Eyes- Motor Scale. Physiological changes expressed by ar- terial pressure and heart rate. Subjective pain re- sponse was scored on a Facial Image Scale. Physical physiological and subjectiv…
