background cataract is one of the most common surgical procedures in the elderly. in most cases, the elderly have cardiac ischemia or chronic coronary diseases, which would lead to more ischemic events during general anesthesia. therefore, surgeons and anesthetists prefer regional aesthesia to the general one owing to its more advantages and less complications. objectives therefore, this study ...

Eye surgeries are performed mostly under orbital regional anesthesia (blocks) owing to their reliability and high patient acceptance. The most commonly used orbital regional blocks include retro-bulbar (intraconal), peri-bulbar (extra-conal) and sub-tenon named according to the site of deposition of local anesthetic agent. Many variations of these block techniques do also exist. Although these ...

BACKGROUND Retro-bulbar anesthesia is one of the most common regional blocks used for intraocular surgeries. Complications associated with regional blocks may be limited to the eye or may be systemic. CASE REPORT After a retro-bulbar block for glaucoma surgery, a 60-year-old man developed loss of consciousness, apnea with hypotension and bradycardia-features of brainstem anesthesia. We presen...

        Ewing's sarcoma is a relatively common malignant bone tumor that typically occurs in long bone diaphyses of adolescents and young adults of 10-30 years old. Often times, all Ewing's sarcoma of bone have radiographic abnormalities. Diagnosis is usually delayed and can be misdiagnosed as osteomyelitis. Bone to bone metastasis occurs, but soft tissue retro bulbar metastas...

Retro-bulbar sinus puncture and facial vein phlebotomy are two widely used methods for blood sampling in laboratory mice. However, the animal welfare implications associated with these techniques are currently debated, and the possible physiological and pathological implications of blood sampling using these methods have been sparsely investigated. Therefore, this study was conducted to assess ...
