Abstract
Anesthesia for patients with open globe injury who need emergency surgical intervention may be hazardous. When the eye globe is open, any factor that increases the intraocular pressure (IOP) may possibly cause drainage of the aqueous humour or extrusion of the vitreous humour through the wound, which can permanently damage vision Succinylcholine is used to facilitate rapid tracheal intubation in highrisk patients for aspiration because of its fast onset time and excellent intubating conditions.However,It is associated with an increase in the IOP.Laryngoscopy and tracheal intubation further aggravate the rise in IOP Various methods have been used to attenuate the effects of succinylcholine on IOP. They included self-taming, where a small dose of succinylcholine is given initially followed by the remaining amount of succinylcholine, and pretreatment with non-depolarizing neuromuscular blocking agents, lidocaine, narcotics, nifedipine, and nitroglycerin However, no modality was devoid of drawbacks and limitations.
