An interventional study of Cannula plastic part while applying peribulbar block and traditional technique in Intravenous Cannula Regional Ophthalmic Anesthesia, sponsored by Research Institute of Ophthalmology, Egypt. Completed at 1 site in Egypt. Open to participants aged 18 Years to 80 Years. Per ClinicalTrials.gov, last updated 2022-10-10.
Sponsored by Research Institute of Ophthalmology, Egypt · Not applicable, Interventional, and Other
This study is conducted to determine the efficacy of the cannula atraumatic technique as an alternative to the traditional needle penetrating technique to minimize the incidence of accidental globe penetration and/ or perforation, as the plastic part of the cannula is blunt and is difficult to perforate the normal globe being marble-like in consistency.
A prospective comparative single blinded randomized controlled clinical study was held in the operating theatre at Research institute of ophthalmology, on adult patients with age group between 18- 80 years of both sexes undergoing anterior, posterior segment or plastic surgeries. two techniques were used in comparison: the atraumatic technique, using a 20 or 22-gauge cannula advanced in the inferior-temporal peribulbar space after local infiltration. The skin and the conjunctiva will be pierced by the cannula and advanced for only 0.5 cm, then the cannula will be advanced blindly. Supplementation using the other sites (medial canthus and superior nasal) as needed.
Research Institute of Ophthalmology, Egypt is the lead sponsor of 11 studies on the registry; 2 are open to participants now.

Exclusion Criteria:
a cannula is used to apply ophthalmic block
Device: Cannula plastic part while applying peribulbar block
a 24 or 25 gauge needle is used to provide regional o anesthesia to the study group
Procedure: traditional technique
Using the cannula and introducing it peribulbar to apply regional ophthalmic anesthesia avoiding by this causing trauma to the globe, as the normal globe consistency is marble-like, the cannula can't puncture except in case of presence of staphyloma, so the cannula will either curve around it or will be kinked causing failure of the technique.
Also known as: Atraumatic peribulbar technique
the patients are going to receive the local anesthetic standard of care technique by using 23- or 24-gauge needle introduced through the skin extra-conal and local anesthetic solution will be injected with volume AND concentration according to the surgery going to be done
Also known as: needle traumatic peribulbar anesthesia
Safe Ophthalmic block using Globe Akinesia Score by Sarvela
A scoring system out of 12 to assess the four recti muscles, orbicularis oculi and the levator palpebri superioris degree of akinesia post regional anesthesia where 2 is full movement 0 is total block, and also the anesthesia is assessed where 2 is full sensation and 0 is considered total anesthesia
