Summary
The aim of this randomized trial is to assess the efficacy of preventive analgesia using
different peribulbar blocks (PBB) under SPI-guided anaesthesia for vitreoretinal surgery
(VRS), presence of PONV (postoperative nausea and vomiting) and oculocardiac reflex (OCR) and
compare Numerical Rating Scale (NRS) with Surgical Pleth Index (SPI) for monitoring pain
perception postoperatively.
Patients will receive general anaesthesia combined with either preventive PBB using either
lidocaine with bupivacaine or bupivacaine or ropivacaine
