AIMS To test if the simple technique of warming lignocaine reduces the pain of injection during local anaesthetic cataract surgery. METHODS Sixty patients undergoing peribulbar local anaesthesia for cataract surgery were allocated randomly to receive either warm (37 degrees C) or cold (room temperature) plain 2% lignocaine for the injection. Pain was assessed subjectively by asking the patien...

Aims—To determine the relation between pH of anaesthetic solutions and patient perception of pain with peribulbar injection of local anaesthesia. Methods—This prospective randomised controlled double blind pilot study involved 60 consecutive patients who received a peribulbar block with either a standard acidic local anaesthetic of 5 ml 2% lignocaine and 5 ml of 0.5% bupivacaine (solution A), o...

OBJECTIVES To investigate the concentrations of carboplatin and etoposide achieved in the aqueous and vitreous humors after intravenous infusion in nonhuman primates, and to investigate whether local administration of carboplatin might result in higher concentrations in the vitreous humor. METHODS Macaca fascicularis primates were treated with 1 of 3 regimens: (1) intravenous carboplatin (18....

PURPOSE To compare the effects of ropivacaine and bupivacaine-lidocaine combination on intraocular pressure, quality of block, and degree of postoperative pain in peribulbar block. METHODS The study group involved 32 patients undergoing elective cataract surgery under peribulbar block. Patients were divided into two groups according to the local anesthetic used: Group 1 (n=16), ropivacaine 0....

AIMS A prospective study was carried out in order to evaluate the efficacy and safety of peribulbar anaesthesia during keratoplasty and to describe surgical conditions. METHODS Of 137 consecutive keratoplasties, 100 (73%) were performed under peribulbar anaesthesia. Patients received a mean volume of 16.5 (SD 4) ml (range 9-22 ml) of a mixture of etidocaine, bupivacaine, and hyaluronidase. Oc...

INTRODUCTION Orbital cellulits following cataract surgery is extremely rare. We describe a case of orbital and facial cellulitis that occurred after routine cataract operation with peribulbar anaesthesia. There were no preoperative systemic or ocular risk factors for postoperative infection. CASE DESCRIPTION An 89-year-old man presented to eye casualty, the day after he underwent an uneventfu...
