Local versus general anaesthesia for adults undergoing pars plana vitrectomy surgery

Abstract

Local versus general anaesthesia for adults undergoing pars plana vitrectomy surgery.

Safety and efficacy of intravenous oxycodone in geriatric patients undergoing general anesthesia for ophthalmic surgeries:a randomized controlled trial

“…As the elderly comprises a substantial and rapidly-growing portion of the ophthalmology surgical patient population, their specific requirement for perioperative analgesics ought to be carefully considered [2][3][4]. Intravenous fentanyl has been one of the most commonly used opioids for general anesthesia in ophthalmology procedures.…”

“…However, geriatric patients may present more comorbidities that are not suitable for local or regional anesthesia [3]. In addition, general anesthesia is often indicated in some ophthalmic procedures that may require more intraoperative manipulation and longer operating time, such as glaucoma and retina surgeries [3,4].…”

Definitions of anaesthetic technique and the implications for clinical research

“…Hip fracture surgery (2016) [40] Peripheral nerve blocks with or without sedation Neuraxial blocks, with or without i.v. sedation Any technique where a tracheal tube or a laryngeal mask airway was used Carotid endarterectomy (2013) [41] LA of any type, including both epidural and skin or deep infiltration -'All studies used standard medication in the general anaesthetic group' Pars plana vitrectomy (2016) [42] 'Injections or topical application of local anaesthetic drugs are used to block sensation to a very small and specific area of the body'…”

Effectiveness of single injection sub-Tenon’s block for Pars Plana Vitrectomy and associated procedures

“…However, there is a recent Cochrane review comparing general versus regional anaesthesia [1]. Host of factors influence the specifics of PPV surgery resulting in varying preferences of anaesthesia and surgery.…”

“…This block has the advantages of avoiding serious albeit rare but well-known complications of the needle-based blocks [15]. The duration of anesthesia can be extended by simply injecting additional local anaesthetic agent through the initial dissection midway through the procedure on the operating table by the operating surgeon under sterile conditions [1]. Anaesthesia, akinesia and duration of sub-Tenon's block may be affected by several factors including the size of globe, orbital cavity, anaesthetic agent, volume, adjuvant and intraocular pressure lowering device [16,17].…”
