When eyes are untaped during general anaesthesia, the incidence of ocular injury has been reported to be as high as 44%. [1] [2] If tape is used to hold the eyes closed, ocular injury occurs during 0.1-0.5% of general anaesthetics, and is usually corneal in nature. [3] [4]
During the surgery, it has to be ensured that no carbon dioxide retention occurs. If this occurs, the choroid swells up and ocular contents may prolapse as soon as the eye is opened. The advantages of general anaesthesia is that it produces complete akinesia, controlled intraocular pressure and safe operating environment. It is the safest ...
General anaesthesia (UK) or general anesthesia (US) is medically induced loss of consciousness that renders a patient unarousable even by painful stimuli. [5] It is achieved through medications, which can be injected or inhaled, often with an analgesic and neuromuscular blocking agent .
Anaesthesia may be placed topically as eyedrops or injected next to (peribulbar) or behind (retrobulbar) the eye [6] or sub-tenons. Local anaesthetic nerve blocking has been recommended to facilitate surgery. [2] Topical anaesthetics may be used at the same time as an intracameral lidocaine injection to reduce pain during the operation. [6]
Any additional time under anesthesia is usually related to ensuring that patients are safely cared for, such as securing a safe airway, or responding to physiologic changes that may occur because ...
Eye injury by impact of small plastic body. Based on the injury to the eyewall (outer fibrous coat of the eye consisting of cornea and sclera) Closed globe injury: the eye globe is intact, but the seven rings of the eye have been classically described as affected by blunt trauma. Types include contusion and lamellar laceration
BEIRUT — An eye doctor in Lebanon said he has treated some 40 to 50 people with serious injuries, including some who lost both eyes, after a wave of communication device explosions targeted ...
Systemic complications include local anesthetic toxicity, brainstem anesthesia, and stimulation of the oculocardiac reflex. Most commonly, patients will report discomfort during the performance of the block, such as the sensation of the needle during insertion and/or pressure behind the eye during injection.
