Retrobulbar blockade during eyeball enucleation surgery in children with retinoblastoma

Retinoblastoma (RB) is a malignant tumor of the embryonic nerve retina.Purpose. To determine the effectiveness of retrobulbar blockade (RbB) with ropivacaine 0.5% for intra- and postoperative analgesia, as well as for the prevention of oculocardial reflex (OCR), postoperative nausea and vomiting (PO...

Zusammenfassung:Retinoblastoma (RB) is a malignant tumor of the embryonic nerve retina.Purpose. To determine the effectiveness of retrobulbar blockade (RbB) with ropivacaine 0.5% for intra- and postoperative analgesia, as well as for the prevention of oculocardial reflex (OCR), postoperative nausea and vomiting (PONV) during enucleation.Material and methods. A prospective randomized controlled clinical trial was performed. Eighty patients aged 0 to 10 years were included, who were randomly assigned to the RbB group (retrobulbar blockade with ropivacaine 0.5% with general anesthesia) (n=40) and the GA control group (general anesthesia) (n=40).Results. There were no complications in the RbB group caused by the methodology. In the intraoperative period, the average dose of fentanyl in the RbB group was 4.7±0.7 μg/kg, which is significantly lower than in the OA group of 10.1±1.9 μg/kg (p
