Ultrasound navigation during blockade in children with retinoblastoma with enucleation of the eyeball

Introduction. Regional blockades in children ophthalmology operations are used not only for analgesia the intra- and postoperative period, but also prevention of oculocardial reflex (OCR), nausea vomiting (PONV). But there is still no convincing data on advantages methods retrobulbar blockade (RBB) performed under ultrasound guidance parabulbar (PBB) guidance. Aim. In present study, we investigated efficacy safety RBB with ropivacaine 0.5 % OCR pain, as well PONV when detected PBB upon detection enucleation eyeball. Materials methods. A prospective randomized arterial study was period 2016–2022. The included 110 patients established inclusion criteria. were divided into two groups: 55 who a + ultrasound. Evaluated: likelihood introduction opioid analgesics, quality anesthesia, duration block complications. Results. There decrease intraoperative diseases group, where average dose fentanyl increased by 4.1 ± 1.4 μg/kg, group it 9.7 1.8 μg/kg (p < 0.05 ). time to first frequency analgesic 6.7 hours 11.7 3.3 0.05). Conclusions. significant difference between It revealed that reduces requirements, stable hemodynamics longer analgesia. Therefore, use eyeball retinoblastoma preferred technique.
