Etude de l'ANesthésie Par Gel de Lidocaïne Pour Les Injections IntrA vitréennes (ANGLIA)
Purpose To assess the efficacy of preservative-free Lidocaine gel 2% (LG) in patients complaining of pain during intravitreal injection (IVI) despite standard topical anaesthesia.
Methods First phase: prospective selection of a group of painful patients (score pain ≥ 4 on Visual Analogic Scale) during IVI with anaesthetic drops. Determination of the anxiety score before IVI, the overall pain score and pain score related to the speculum after IVI. Painful patients were proposed to enter the second phase of the study and have the next IVI with LG. Pain scores and anxiety score after each method of anaesthesia were compared.
Results In a group of 240 patients, 62 (25%) described pain≥4 despite anaesthetic drops. 39 patients (16.3%), accepted anaesthesia with LG for the next IVI. During IVI with LG, 27 patients (69%) had pain<4 (P<0.001). The average pain score for IVI with LG was 3.32+/-2.45 versus 5.71 +/-1.45 for anaesthetic drops (P<0.001). Pain score due to speculum placement was 1.54+/-1.96 for LG versus 2.66+/-2.57 for drops (P=0.02). Anxiety score before IVI was 8.08+/-3.63 for LG versus 7.84+/-3.84 with drops (P=0.4). 27 patients (69%) wanted to have subsequent IVIs with LG.
Conclusion In a selected group of painful patients, anaesthesia with Lidocaine gel provided a statistically significant decrease of the pain score during IVI and the speculum placement pain score. The similarity of anxiety score before each method of anaesthesia, suggests that the reduction of pain score was truly due to a superior anaesthetic effect of LG.

Detailed Description
Introduction Déterminer l'efficacité d'une anesthésie topique par gel de Lidocaine à 2% (GL) à la place de l'oxybuprocaine chez les patients se plaignant d'une douleur importante lors des injections intravitréennes. (IVT) avec une aiguille 30 gauge.
Matériels et Méthodes Première phase: réalisation d'un premier interrogatoire parmi des patients ayant des IVT unilatérales réalisées par six praticiens pour déterminer 1) la douleur après IVT avec ovybuprocaine, 2) la douleur liée au blépharostat et 3) l'anxiété avant IVT par l'Hospital Anxiety and Depression Scale , et sélectionner un groupe de patients se plaignant d'une douleur ≥ 4 sur une échelle visuelle analogique (EVA) de la douleur et acceptant aussi une anesthésie par GL lors de la prochaine IVT (groupe étudié). Deuxième phase : réalisation d'un deuxième interrogatoire sur le groupe étudié pour déterminer la douleur ressentie après GL (critère principal), déterminer l'anxiété avant les IVT et la douleur lors de la pose du blépharostat. (critères secondaires).
Résultats Sur un groupe de 240 patients 62 (25%) ont décrit une douleur ≥ 4. 39 patients (16,3%) dont 32 femmes (82%) - Age moyen 77 ans ont accepté une anesthésie par GL et ont constitué le groupe étudié. Après IVT avec GL 27 patients (70%) avaient une douleur < 4 (P< 0,001). Le score moyen de douleur après IVT était de 5,71 +/- 1,45 pour l'oxyburpocaine contre 3,32 +/- 2,45 pour le GL (P< 0,001). Lors de la pose du blépharostat la douleur était de 2,66 +/- 2,57 avec l'oxybuprocaine contre 1,54 +/- 1,96 avec le GL (P= 0,02). Le score d'anxiété avant IVT était de 7,84 +/- 3,84 avant IVT avec oxybuprocaine contre 8,08 +/- 3,63 (P=0,4). 27 patients (69%) souhaitaient avoir des IVT ultérieures avec du GL.
Discussion Le gel de Lidocaine possède une autorisation de mise sur le marché pour la chirurgie ophtalmologique. Dans notre étude, il a permis une réduction significative du score de douleur après IVT en comparaison avec une anesthésie précédente par oxybuprocaine. Il a aussi permis une réduction de la douleur lors de la pose du blépharostat. Ce médicament est pour l'instant réservé à un usage professionnel et n'est pas disponible en officine ce qui restreint son utilisation aux IVT réalisées dans des établissements de santé.
Conclusion L'utilisation de Gel de Lidocaine a permis une réduction significative de la douleur après IVT chez un groupe de patients algiques et plus des deux tiers d'entre eux souhaitaient poursuivre les IVT avec ce type d'anesthésique.
