Objectives: Esophagogastroduodenoscopy (EGD) performed with topical pharyngeal anesthesia presents less adverse events and post-procedural impairment associated with sedation. The aim of this study was to evaluate if by combining Flurbiprofen and Lidocaine sprays for topical pharyngeal anesthesia there is an improvement in patient tolerance and endoscopist satisfaction in comparison to using Lidocaine spray alone.
Methods: We conducted a single center, double blind, randomized controlled trial designed to compare unsedated EGD using topical Flurbiprofen spray (Strepsils Intensive
®) plus Lidocaine spray versus Lidocaine spray alone. We assessed patients’ tolerance and endoscopist satisfaction through a 0 to 10 points visual numerical rating scale.
Results: A total of 36 patients were included and randomized in two equal groups: Lidocaine and Flurbiprofen spray group (FL) and Lidocaine spray group (L). No significant differences were found amongst groups for patient discomfort score (FL 5.33 ± 2.42, L 5.56 ± 2.12,
p = 0.708), pain score (FL 1.77 ± 2.17, L 1.89 ± 0.74,
p = 0.119), gag reflex intensity score (FL 1.61 ± 0.82, L 1.83 ± 0.68,
p = 0.418), patient satisfaction score (FL 7.78 ± 2.46, L 7.22 ± 1.78,
p = 0.428), and endoscopist satisfaction score (FL 7.5 ± 2.87, L 7.58 ± 1.45,
p = 0.312).
Conclusions: During unsedated EGD, both Lidocaine plus Strepsils spray and Lidocaine spray alone were safe and well tolerated. The combination of Flurbiprofen and Lidocaine did not significantly improve patients’ level of discomfort, pain, gag reflex, and satisfaction and endoscopist satisfaction.
