Abstract:

Background & objective: Peribulbar block is a widely used technique for vitreoretinal surgeries due to its safety and efficacy. Adding adjuvants to local anesthetics is known to enhance the quality of the block and prolong the duration of its effect. In this study, we compared the effectiveness of dexmedetomidine and neostigmine as adjuvants to local anesthetic in peribulbar blocks for vitreoretinal surgeries. Methodology: This prospective, randomized, controlled, blinded study was conducted on patients undergoing vitreoretinal surgery under peribulbar block. Patients were randomized into

Abstract:

ABSTRACT Cataract surgery is performed routinely under regional orbital blocks including retrobulbar and peribulbar blocks. Several complications have been reported while performing these blocks, the most significant of which is the local anesthetic systemic toxicity (LAST). The symptoms and signs present in a varied spectrum, but every such case requires early recognition and immediate resuscitation to avoid long-term morbidity and even death. Lipid emulsion therapy forms the mainstay of treatment. We present a case of a 49-year-old man who planned to undergo cataract surgery under the peribu

Abstract: PURPOSE: The purpose of this study was to evaluate the effectiveness of ropivacaine 0.5% and the combination of bupivacaine 0.5% and lidocaine 2% on intraocular pressure (IOP) before and after the peribulbar anesthesia in cataract operation and to know the ideal drug with minimal complications. METHODS: A double-blinded, randomized study was done on 62 patients with cataracts planned for cataract operation under regional anesthesia who were allotted to Group 1 and Group 2: 0.5% ropivacaine was given to Group 1 and 0.5% bupivacaine and 2% lidocaine mixture were given to Group 2.

Abstract:

Background: Peribulbar block for vitreoretinal surgery is rather associated with delayed onset of globe anesthesia, akinesia and short duration of analgesia. Objective: To compare the effect of addition of Magnesium sulphate vs dexmedetomidine to standard local anesthetics mixtures on the time of onset of Globe Anesthesia, Akinesia & analgesia duration. Patients and Methods: Ninety patients of both sexes, aged 25- 75 years, ASA I-III scheduled for vitreoretinal surgery. They were randomly allocated into 3 equal groups each received peribulbar block a mixture of Levo- bupivacaine 0.5% (3 ml

Abstract:

<strong>Background:  </strong>The most common cause of blindness worldwide is cataracts. In a growing nation such as India, where employment is the primary driver of advancement, cataract-related blindness presents a major public health, economic, and social challenge. The anesthetic used during cataract surgery has changed over time in an effort to lower risks and problems. These days, small incision cataract surgery is performed under shorter acting, less invasive anesthetic protocols. This is made possible by advancements in surgical techniques, such as smaller and self-sealing wounds,

Abstract:

Background: Patients admitted for cataract surgery have a fear of worst pain due to peribulbar injection for anaesthesia rather than surgery itself. The aim of this study is to find out the threshold of pain associated with the anaesthetic peribulbar injection for cataract surgery.Methods: This prospective randomised study was carried out at Ophthalmology department of Maharishi Markandeshwar University from 10 January 2017 to 22 March 2017. 100 patients undergoing elective cataract surgery were administered a peribulbar block. Before injection all patients were briefed about the procedure and

Abstract:

ABSTRACT Introduction: Cataract surgery is performed under peribulbar or retrobulbar block. Majority of the patients posted for cataract have some form of medical diseases like diabetes, hypertension, angina, ischaemic heart disease etc. Lidocaine and bupivacaine are the most commonly used local anesthetic for the block procedure. Here we compare the efficacy of peribulbar block in cataract surgery using the combination of 1:1 mixture of 2% lidocaine with 0.5% bupivacaine and 1:1 mixture of 2% lidocaine with 0.75% ropivacaine. Materials and Methods: It is a prospective, randomized, double blin

Abstract:

Hyaluronidase is a hydrolytic enzyme that helps in breaking down hyaluronic acid, a component of the extracellular tissue matrix, thereby facilitating the dispersion of local anaesthetic drugs through tissue planes. It is a key component in peribulbar anaesthesia for ocular surgeries. Allergic response to hyaluronidase is relatively rare but a potentially vision-threatening complication. A preoperative intradermal hypersensitivity test is useful to detect such cases and avoid potential complications. Here we report a case of hypersensitivity reaction to hyaluronidase after peribulbar anaesthes
