Official Title: Influence of Surgical Pleth Index-guided Analgesia With Different Techniques on the Presence of Postoperative Pain, Nausea and Vomiting and of Oculocardiac Reflex in Patients Undergoing Vitreoretinal
Brief Summary:
The aim of this randomized trial is to assess the efficacy of SPI-directed analgesia for vitreoretineal surgery, presence of PONV and oculocardiac reflex and compare Numerical Rating Scale (NRS) with Surgical Pleth Index (SPI) for monitoring pain perception postoperatively.
Patients received general anaestesia alone or combined with either preemptive analgesia using topical solution of 0,5% proxymetacaine or peribulbar block (0,5% bupivacaine with 2% lidokaine) or preemptive intravenous infusion of 1,0 g of metamizol or preemptive intravenous infusion of acetaminophen in a doseof 10-15mg/kg of body weight.
