We describe a case of surgical emphysema, pneumomediastinum and bilateral pneumothoraces which occurred some hours after general anaesthesia for a repeat laparoscopy and followed persistent nausea and vomiting. We report the case because of the unexpected and delayed appearance, which led to delay in diagnosis and management. We suggest that this(More)
Recently published literature shows that most patients experience a variety of visual sensations during cataract surgery under local anaesthesia. Most patients (80-100%) retain at least some light perception in the operated eye and many also experience a variety of other visual sensations during cataract surgery under regional ophthalmic anaesthesia(More)
Complications following ophthalmic regional anaesthesia are rare but are reported during both needle (intraconal and extraconal blocks) and blunt cannula (sub-Tenon's block) techniques. At present there is no perfect technique of ophthalmic regional anaesthesia. This article reports on the complications, treatment and prevention of commonly used ophthalmic(More)
Serious complications following orbital regional anesthesia are rare, but occur following both needle and blunt cannula (sub-Tenon's) techniques. Each technique of orbital regional anesthesia has its own risk/benefit profile. This article reviews the etiology, risk factors, treatment and prevention of complications of commonly used akinetic orbital blocks.(More)
INTRODUCTION A case is presented of a patient with severe and chronic pain in the orbital region, which was relieved by retrobulbar injection of absolute alcohol. The management of chronic pain in the orbital region has received little attention and the literature is reviewed. CLINICAL PICTURE A 52-year-old man with adenoid cystic carcinoma of the(More)
A prospective, randomized blind study was conducted in 40 patients undergoing phacoemulsification and posterior chamber intraocular lens implantation. They received anaesthetic infiltration of 2% lidocaine with 1:200,000 epinephrine and hyaluronidase 150 U ml(-1) in a volume of 2, 3, 4 or 5 ml into the sub-Tenon's fascial space through a Greenbaum cannula(More)
The place of sub-Tenon's block in ophthalmic surgery is now established. This block was introduced into clinical practice in the early 1990s as a simple, safe and effective technique. Since then, techniques have evolved, newer cannulae have been introduced and many complications, both minor as well as major, have been reported. This review deals with the(More)
AbstractPurpose To compare the quality of anaesthesia and complication rates between three sub-Tenon cannula of increasing length (anterior Greenbaum, mid Kumar–Dodds, and posterior Steven's sub-Tenon's cannulae).Methods A total of 150 patients undergoing cataract extraction were randomised to receive a sub-Tenon injection of 5 ml of 2% lidocaine with(More)
