Anesthesia in retinopathy of prematurity.

Abstract

Retinopathy of prematurity (ROP) remains among the leading causes of childhood blindness. It affects mainly premature infants who tend to be systematically and clinically unstable and are more prone to complications and anesthesia related adverse effects when undergoing examination or treatment. A better comprehension of different analgesic and anesthetic methods used during screening and treatment may help in choosing a suitable option for ROP screening and treatment. An electronic search was done using MEDLINE, PubMed, and Embase databases. Search terms used included ROP, ROP, ROP screening, ROP treatment, analgesia, and anesthesia. All randomized clinical trials, large case series, and surveys were included in the review. Topical proparacaine is the most commonly used anesthesia during ROP screening and may significantly ease pain during ROP screening. Different comfort measures during screening may help infants recover faster but do not abolish pain. Topical tetracaine seems an effective pain-relieving option during intravitreal injections for ROP treatment. Photocoagulation of the peripheral retina under general anesthesia is considered the most common practice in the treatment of ROP. Further work is necessary to better understand the options of anesthesia methods offered for the treatment of ROP patients. This is a comprehensive review highlighting the available anesthetic methods for ROP patients to aid ophthalmologists in determining the most common and current anesthetic and analgesic practices.
