low volume peribulbar

Melissa De Regge, Paul Gemmel, Philippe Duyck, Ilse Claerhout
PURPOSE: To detect factors contributing to variation in cataract surgery processes. METHODS: A multilevel study was conducted to compare the process of cataract surgery between hospitals in Belgium. The main data were collected through non-participative observations and time measurements in four hospitals. Surgeons (n = 16) performing cataract surgery in the selected region and their patients (n = 274) undergoing cataract surgery were observed. Flow efficiency is measured in the operating room (OR) as time for preparation, surgery, exit and turnover...

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 offers increased safety, simplicity, low cost, and little change to instrumentation.

PURPOSE: To compare the efficacy and safety of single-injection inferomedial (IM) and conventional inferotemporal (IT) peribulbar blockades. PATIENTS AND METHODS: This prospective randomized study included 200 patients who were randomly allocated into two equal groups (n = 100 patients); in the first group, patients received IM peribulbar injection (IM group), while IT peribulbar injection was performed for the second group (IT group). The measurement data were patient characteristics, number of patients who required supplementations, total anesthetic volume injected, surgeon's experience and any recordable complications...

Cataract surgery is the most frequent surgical procedure requiring anaesthesia in developed countries. It is performed mainly in elderly patients, who present with many coexisting diseases that induce subsequent hazards from general anaesthesia. Cataract anaesthesia is performed following various techniques of regional anaesthesia, which are detailed in this review. Needle block carries a low but real risk of complications, mainly because of needle misplacement. Correct teaching and training are mandatory to prevent complications...

PURPOSE: To prospectively analyse the efficacy and safety of peribulbar anaesthesia for penetrating keratoplasty through a noncomparative, consecutive series. METHODS: One hundred twenty-four (91.1%) of 136 patients undergoing penetrating keratoplasty (PK) from January 1997 to December 2001, were administered peribulbar anaesthesia. The anaesthetic mixture consisted 5 ml of lignocaine, bupivacaine, and hyaluronidase (to avoid evaluation bias) in the peribulbar space...

PURPOSE: To evaluate the anesthetic effect of single-point low-volume peribulbar anesthesia supplemented by topical anesthesia. SETTING: Private ambulatory ophthalmic practice. METHODS: Five hundred consecutive patients received 4 cc of lidocaine 2% with 200 units hyaluronidase as 1-point peribulbar anesthesia. This was supplemented by lidocaine 4%, 1 drop every 3 to 5 minutes for 3 instillations. Phacoemulsification and intraocular lens implantation were performed through a scleral tunnel or clear corneal approach...

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) received this solution supplemented with hyaluronidase 50 iu ml-1. Group 3 (n = 75) received the same solution supplemented with hyaluronidase 300 iu ml-1...

BACKGROUND: Retrobulbar anesthesia (RETRO), combined with a facial block, is the most frequently employed method of anesthesia in cataract surgery. There is, however, an increasing tendency to use peribulbar anesthesia (PERI), which is claimed to provide the same degree of anesthesia and akinesia as RETRO while reducing many of the complications. OBJECTIVES OF THE STUDY: Survey of the principal techniques of RETRO, facial block and PERI as well as of the most important local anesthetics and additives; quantitative investigation of resulting akinesia and sensory blockade; comparison of systemic and local complications (literature review)...

Because of risks and complications inherent to retrobulbar anesthesia, alternative techniques such as peribulbar and topical approaches have been devised. These also have associated problems. We have developed a technique that combines a single, minimal volume, perilimbal injection with topical anesthesia. It provides sutureless scleral tunnel cataract surgery without the risks of retrobulbar or peribulbar anesthesia, maximizing patient comfort and allowing immediate return of vision postoperatively.

A prospective trial was conducted on 142 patients who underwent cataract surgery, to compare the efficacy of a single point, low volume peribulbar with that of retrobulbar anaesthesia. It was found that peribulbar anaesthesia is as efficacious as retrobulbar anaesthesia without the associated complications. It also avoids the facial block used by most ophthalmologists to supplement a retrobulbar block, thus markedly reducing the post-operative patient discomfort as well as the total volume of anaesthetic used...

UNLABELLED: In a study of 280 patients (265 with cataract, 15 with strabismus), we investigated the ocular circulatory effects of 3 methods of anesthesia widely used in ophthalmic surgery, retrobulbar, peribulbar and general anesthesia. Retrobulbar anesthesia (RETRO) was performed with 2, 5 or 8 ml of a mixture (BLH-Mix) of bupivacaine 0.75%, lidocaine 2% and hyaluronidase; with 5 ml BLH-Mix and addition of adrenaline in a low (1:500,000) or a higher (1:200,000) concentration; with 5 ml bupivacaine 0...
