title: Anesthesia protocols for early vitrectomy in former preterm infants diagnosed with aggressive posterior retinopathy of prematurity.
abstract: Aggressive posterior retinopathy of prematurity (ROP) can, if left untreated, rapidly progress to total retinal detachment within 1-2 weeks. Early surgical intervention with vitrectomy has been attempted to treat and prevent further retinal detachment. We investigated the anesthetic management of 29 infants with aggressive posterior ROP undergoing early vitrectomy. Postmenstrual age at surgery ranged from 35 to 47 weeks (median 41). Weight ranged from 1408 to 3478 g (median 1875). All infants underwent general anesthesia with fentanyl and sevoflurane. Mean surgical and anesthetic times were 88.6 and 143.6 min, respectively. In two patients, vitrectomy was postponed for one week due to enteric perforation in one patient and meningitis in the other, because the anticipated perioperative risk was deemed high. There were no intraoperative complications, except in one patient who developed pulmonary edema following upper airway obstruction. All patients survived to be discharged from NICU or transferred to the referring hospital. In all cases, complete or partial retinal reattachment was successfully achieved. Early vitrectomy for aggressive posterior ROP may be effective despite associated perioperative risks. As this condition progresses rapidly, prompt preoperative organization, including anesthetic planning, is important and useful. Anesthesiologists can play an important role in the perioperative management of such high-risk infants.
