Study of Two-step Anesthesia in Posterior Vitrectomy

Status Recruiting

Clinical Trial Summary

A prospective, randomised, single-masked comparison of local anaesthetic approaches including topical anesthesia combined sub-conjunctival anesthesia(two-step anesthesia) for minimally invasive vitrectomy（TAMIV）vs peribulbar block vs retrobulbar block

Clinical Trial Description

Purpose: topical anesthesia combined sub-conjunctival anesthesia(two-step anesthesia) for minimally invasive vitrectomy Methods: This prospective, randomized, single-blinded clinical trail is conducted at Shanghai Aier Eye Hospital. Selected group of 60 patients with retinal-vitreous diseases will be randomized divided into 3 groups and underwent 25-gauge vitrectomy. Group1 uses two-step anesthesia , whereas Group 2 uses retrobulbar anesthesia, group 3 uses peribulbar anesthesia. A 5-point Visual Analogue Pain Scale is used to assess patients' pain score and surgeon's ease while operating. Any complications therefore will be made note of. ;
