Dr. Jitendra Kumar, Dr. Kanhaiya Prasad

Abstract :

 

Ophthalmic surgery has been performed under a wide range of anaesthetic techniques as like peribulbar, retrobulbar, Sub–tenon, topical anaethesia, intracameral etc. In Peribulbar block, the anaesthetic is injected into the extraconal compartment of the eye. Thus, most of the complications associated with retrobulbar anaesthesia are avoided. The main aims of study were– A) to evaluate the various complications of peribulbar block. B) Effect of the size of needle in peribulbar block. C) Various factors that cause complications in peribulbar block.  A total of 850 Patients with peribulbar block, were included in this observational study conducted in the Department of Ophthalmology, MLBMC, Jhansi, over a period of 12 months. The preoperative assessment done and detailed clinical history was taken.After 15–20 min of peribulbar block patient were kept under observation and all cases undergone for routine ophthalmological examination like torch light examination, slit lamp examination. All cases were divided into two groups –Group A– Peribulbar block with 24 gauge needle. (NA=450), Group B– Peribulbar block with 26 gauge needle. (NB=400). The common complications were conjunctival chemosis (23.06%), periorbital edema (14.71%), Lid hemorrhage (5.53%), retrobulbar hemorrhage (1.05%), globe perforation (0.12%), and mayotoxicity (0.24%). The incidence of complications  were depends on many factors like size of needle, experience hands, patient’s cooperation, past history of patient’s, amount of block solution etc. So, proper anatomical knowledge, preoperative assessment, proper examination, counseling of the patients play significant role to avoid these complications.
