An 82-year-old ASA 2 patient underwent routine sub-Tenon's block for cataract surgery. One minute after injection of the local anaesthetic, the patient had a generalised tonic-clonic seizure and developed refractory ventricular fibrillation; subsequent resuscitation was unsuccessful. With no evidence for intravascular injection, the lack of structural brain abnormalities, and the most striking feature on post mortem examination being severe triple vessel coronary artery disease, it was concluded that this was primarily cardiac in origin; however, the possibility of brainstem anaesthesia should also be considered.

Sub-Tenon's Block in Patients with Previous Encircling Band Surgery-A Feasibility Study.

During the COVID-19 pandemic, reducing aerosol-generating procedures became fundamental, particularly in ophthalmic surgeries traditionally performed under general anesthesia (GA). Regional anesthesia, such as sub-Tenon's block (STB), is widely used in vitreoretinal surgeries, offering a safer alternative by avoiding airway manipulation. However, the altered orbital anatomy in patients with previous scleral explant surgery creates unique challenges to STB application.

Department of Anesthesiology and Reanimation, Faculty of Medicine, Osmangazi University, Büyükdere Mh, Odunpazarı, 26040, Eskişehir, Turkey.
Background: Ophthalmic procedures are increasingly being performed under regional anesthesia techniques such as peribulbar and incisionless sub-Tenon's blocks. The aim is to compare peribulbar block with incisionless sub-Tenon's block in terms of perioperative complications in patients who underwent cataract and vitreoretinal surgeries.
Methods: The patients who underwent cataract or vitroretinal surgery under peribulbar block or incisionless sub-Tenon's block were included in the study.

National Healthcare Group eye Institute, Tan Tock Seng Hospital, Singapore.
Purpose: To elucidate etiology and management of retropupillary sulcus migration of intravitreal gas after uneventful retinal detachment repair surgery.
Methods: 70 year old Caucasian man presented with a temporal macula-off rhegmatogenous retinal detachment. 25-gauge (25G) pars plana vitrectomy was performed with cryopexy to retinal tear and 12% C3F8 gas tamponade under sub-Tenon's anaesthesia.

A retrospective data analysis was performed on 17 eyes from 13 horses which underwent a sub-Tenon's injection to facilitate phacoemulsification or pars plana vitrectomy under general anesthesia between 2018 and 2022. All procedures were performed by the same veterinary ophthalmologist. Seven eyes received a sub-Tenon's dose of 7 ml lidocaine (XylocainÒ, 2 % lidocaine hydrochloride, Germany, Aspen Germany GmbH), and 10 eyes received 7 ml mepivacaine (MepinaestÒ purum 2 %, mepivacaine hydrochloride, Switzerland, Gebro Pharma GmbH).

Sub-Tenon's block has a superior safety profile and life-threatening complications such as cardiovascular collapse and brainstem anaesthesia are extremely rare. We report a case of cardiorespiratory collapse following bilateral sub-Tenon's blocks at the conclusion of a laser photocoagulation procedure under general anaesthesia. The cause was most likely brainstem anaesthesia.
