title: General anesthesia with endotracheal intubation for cryotherapy for retinopathy of prematurity.
abstract: We present a technique for treating retinopathy of prematurity (ROP) with cryotherapy under general anesthesia, administered and monitored by a neonatologist, with endotracheal intubation in the neonatal intensive care unit that avoids the serious systemic complications associated with the administration of local anesthetics. Although no significant complications arose in this series, having the intubated infant monitored by trained neonatology staff allows appropriate management should complications arise. We have used this technique to treat 20 eyes with threshold ROP. The mean time to extubation was 40.2 hours. The systemic status and discharge from the neonatal intensive care unit were not influenced by the general anesthesia. This technique allows quick and accurate application of the cryotherapy in a stable and controlled setting. We recommend that physicians consider cryotherapy under general anesthesia with endotracheal intubation for infants with ROP. This technique allows ROP to be treated adequately with minimal risk to the infant.
