Hyaluronidase and peribulbar block.
We have assessed the effect of two concentrations of hyaluronidase on the quality of peribulbar block, using a low volume, single injection technique. We studied 200 patients undergoing elective intraocular surgery, allocated randomly to one of three groups. Group 1 (n = 50) received peribulbar block with 5 ml of a 1:1 mixture of 0.5% plain bupivacaine and 2% plain lignocaine. Group 2 (n = 75) ...
متن کاملTransconjunctival approach to peribulbar block
As increasing numbers of anesthetists perform eye block anesthesia, thorough understandings of peribulbar injection techniques are important for safe practice. There is uncertainty in the literature regarding the optimum needle length, entry point, volume of injectate, and use of single vs double-injection techniques. A modified technique of peribulbar block anesthesia is presented, which offer...
متن کاملNegative pressure pulmonary oedema after septoplasty.
Negative pressure pulmonary oedema (NPPO) is an anaesthetic complication due to acute obstruction of the upper airway, whose main cause is laryngospasm. The pathophysiology involves a strong negative intrapleural pressure during inspiration against a closed glottis, which triggers excessive pressure in the pulmonary microvasculature. Although its diagnosis can be difficult, its recognition help...
متن کاملComplication of Peribulbar Block: Brainstem Anaesthesia.
Peribulbar block is used to obtain anaesthesia and akinesia of the eye by injecting a local anaesthetic around the musclecone. A patient scheduled for cataract surgery received peribulbar block with 6 mL of 2% lidocaine hydrochloride. Following the injection, confusion, hypotension and dilatation of the contralateral pupil rapidly progressed to loss of consciousness and respiratory arrest. The ...
متن کاملDelayed resolution of pulmonary oedema after cocaine/heroin abuse.
Pulmonary oedema lasting six days occurred in a 68 year old man after sniffing cocaine. He also had evidence of parenteral self-administration of heroin. Pulmonary microvascular filtration pressure and permeability were normal. Delayed resolution of the pulmonary oedema may have been caused by a cocaine-induced impairment of sodium and thus fluid transport across alveolar epithelium. Recognitio...
