ophthalmic anaesthesia

Ana Licina, Sharan Sidhu, Jing Xie, Crispin Wan
BACKGROUND: Vitrectomy surgery is one of the commonest ophthalmic procedures performed across the world. It may be performed using general or local anaesthesia encompassing regional or topical anaesthesia depending on a number of factors, including patient suitability, and patient, surgeon or anaesthetist preference. There have so far been no evidence-based recommendations on the best form of anaesthesia for this intervention. There is no clear collated evidence base as to the best type of anaesthesia to reduce harm, and provide best surgical conditions and optimal outcome for patients...

BACKGROUND: Conjunctival myxomas are rare, benign, connective tissue tumours that classically present as slow-growing, painless, well-circumscribed masses (Arch Ophthalmol 124:735-8, 2006; Case Rep Ophthalmol 3:145-50, 2012). There have been 29 cases reported in the literature (Arch Ophthalmol 124:735-8, 2006; Malays J Med Sci 20(1):92-4, 2013; Case Rep Ophthalmol 3:145-50, 2012; Middle East Afr J Ophthalmol 19(3):353-3, 2012). We present a case with atypical features, and emphasize the importance of excisional biopsies for diagnosing indeterminate conjunctival lesions...

BACKGROUND AND AIMS: Midazolam-fentanyl (MDZ:FEN) combination has been routinely used for intravenous sedation in ophthalmic surgeries. Dexmedetomidine (DEX), a recent α2 adrenoreceptor agonist indicated for sedation for ophthalmic use at a loading dose of 0.5 μg/kg over 10 min, can cause deeper plane of sedation and surgeon dissatisfaction. Therefore, we proposed to evaluate the efficacy and safety of two different loading doses of DEX. METHODS: In a prospective study, 60 patients aged 50-70 years, scheduled for retinal surgery under peribulbar block were divided equally to receive either MDZ:FEN or DEX 0...

Ketamine is a non-barbiturate cyclohexamine derivative which produces a state of sedation, immobility, analgesia, amnesia, and dissociation from the environment. One of the most important advantages of ketamine premedication is production of balanced sedation with less respiratory depression and less changes in blood pressure or heart rate. As its effects on intracranial pressure, the possible effect of ketamine on intraocular pressure has been controversial overtime. In this study, we aimed to demostrate all the advantages and possible side effects of ketamine premedication in 100 children with retinablastoma undergoing ophthalmic surgery...

CASE REPORT: A 4-year-old male diagnosed with Goldenhar syndrome, with an unremarkable ophthalmic history, develops a neurotrophic ulcer secondary to trigeminal nerve aplasia. It was treated with multilaminar amniotic membrane transplantation. DISCUSSION: Trigeminal nerve aplasia is not usually reported in Goldenhar syndrome. Therefore, it seems necessary to perform routine eye examinations, from an early age, to prevent serious complications associated with corneal anaesthesia...

BACKGROUND: An estimated 285 million persons are visually impaired globally, and 39 million of them are blind. Majority of the blind population reside in developing countries. Over 60% of blindness is attributable to surgical causes of blindness. A surgical audit reveals areas of performance that require improvement. AIM: To assess the output and pattern of minor ophthalmic surgeries over a seven year period. METHOD: The minor ophthalmic surgical records of Jos University Teaching Hospital, Jos, Nigeria were retrospectively reviewed to obtain information on the patients'demographics, diagnosis, indication, type of surgery, type of anaesthesia administered, outcome of management, histology report and the rank of surgeon...

Apert syndrome is a rare congenital disorder characterized by craniosynostosis, midface hypoplasia and symmetric syndactyly of hands and feet. Abnormalities associated with Apert syndrome include premature fusion of coronal sutures system (coronal sutures and less frequently lambdoid suture) resulting in brachiturricephalic dismorphism and impaired skull base growth. After this brief explanation it is clear that these anatomical abnormalities may have a negative impact on the ability to perform essential functions...

AIM: In general anaesthesia (GA) for ocular surgery the chosen non-depolarising muscle relaxant has a high influence on the fluctuations of intraocular pressure (IOP) and ocular pulse amplitude (OPA). PATIENTS AND METHODS: In 229 patients, who needed GA for their ophthalmic surgery, OPA and IOP were measured with the dynamic contour tonometer (DCT) before and 5 minutes after intubation. For GA, three groups of non-depolarising muscle relaxants, namely, mivacurium (n = 71), atracurium (n = 91) and rocuronium (n = 67) were used...

Advances in ophthalmic surgery, together with achieving greater patient safety, have changed the requirements of regional anaesthesia of the eye, orbit, and periocular skin. Patient comfort, safety, and low complication rates are essentials of regional anesthesia, which includes invasive procedures that generate intraoperative and postoperative analgesia, as well as akinesia. We present the currently used local anesthesia (topical and subcutaneous infiltration of local anesthetics) and regional anesthetic techniques in ophthalmic procedures, describing the techniques, advantages, disadvantages, and complications in ophthalmic regional blocks, as well as some educational measures to implement them to reduce the risk of ocular complications...
