Abstract:
The background of sudden sensorineural hearing loss is that occurs suddenly, with unknown causes, and the number of cases increases with age. The modality of therapy that is often used today is empiric therapy. The purpose of this literature review is to determine the impact of adding hyperbaric oxygen therapy compared to standard therapy in cases of sudden sensorineural hearing loss. Methods The article search was carried out in various valid online data centers, namely PubMed, Science Direct, Cochrane Library, and Google Scholar.

Introduction: Previous studies have highlighted hyperoxia-induced microcirculation modifications, but few have focused on hyperbaric oxygen (HBO) effects. Our primary objective was to explore hyperbaric hyperoxia effects on the microcirculation of healthy volunteers and investigate whether these modifications are adaptative or not. Methods: This single centre, open-label study included 15 healthy volunteers. Measurements were performed under five conditions: T0) baseline value (normobaric normoxia); T1) hyperbaric normoxia; T2) hyperbaric hyperoxia; T3) normobaric hyperoxia; T4) return to norm

Abstract:
Background: Spinal anaesthesia has been widely used since its introduction in 1898 due to its safety and advantages over general anaesthesia. However, traditional agents like bupivacaine have some disadvantages, including cardiovascular effects and longer duration of action. Ropivacaine has emerged as a potential alternative with reduced cardiovascular toxicity. The study was aimed to compare the efficacy and suitability of 0.75% hyperbaric ropivacaine with 0.5% hyperbaric bupivacaine in patients undergoing lower limb and endoscopic urological surgeries, evaluating onset, quality, duration of

Background: Cystoscopy is a urologic procedure performed as a diagnostic or a therapeutic intervention, usually requiring spinal anesthesia (SA). Bupivacaine is a frequently used spinal anesthesia agent. However, the prolonged duration of its effect is a disadvantage.

Aim: To explore the impact of dexmedetomedine as adjuvant to hyperbaric bupivacaine 0.5% in spinal anaesthesia in caesarian section. Methods: This study was conducted in Services Hospital, Lahore from 23-2-21 to 31-05-21. Two groups of 30 each were made by dividing patients randomly. Group B was given hyperbaric bupivacaine 0.5% (10mg) diluted in normal saline and in Group BD dexmedetomedine 5µg (0.5 ml) was added to 10mg hyperbaric bupivacaine (0.5%). Spinal Anaesthesia was administered with 25G spinal needle. Haemodynamic changes, onset and duration of sensory and motor block were documented

Abstract:
Background Prepectoral tissue expander (TE) placement is an increasingly used breast reconstruction technique but may have a higher risk for mastectomy skin flap ischemia compared to subpectoral TE placement. Hyperbaric oxygen therapy (HBOT) has been shown to salvage compromised mastectomy skin flaps, but there is limited evidence on which patients require HBOT and benefit most from this treatment. Methods We retrospectively reviewed patients undergoing immediate TE breast reconstruction over a 6-year period. Patient demographics, intraoperative data, HBOT treatment, complications, and final b

Abstract:
Bupivacaine is commonly used for spinal anaesthesia. The baricity of bupivacaine (isobaric vs. hyperbaric) may influence the spread, level of the block and the subsequent haemodynamic effects of the spinal anaesthesia. This review considers the available literature on the effect of baricity on the haemodynamic sequelae of spinal anaesthesia with bupivacaine. A literature search was conducted of the MEDLINE and EMBASE databases up to February 2024, following PRISMA guidelines. Randomised controlled trials (RCTs) comparing isobaric and hyperbaric bupivacaine in non-obstetric surgeries were inclu
