Orbital regional anesthesia: complications and their prevention

Indian J Ophthalmol. 2006 Jun;54(2):77-84. doi: 10.4103/0301-4738.25826.


Serious complications following orbital regional anesthesia are rare, but occur following both needle and blunt cannula (sub-Tenon's) techniques. Each technique of orbital regional anesthesia has its own risk/benefit profile. This article reviews the etiology, risk factors, treatment and prevention of complications of commonly used akinetic orbital blocks. Ophthalmologists and ophthalmic anesthesiologists must be prepared to deal with rare, but serious complications, that can occur with any technique of orbital regional anesthesia.
