Evaluation of impact of epidural volume extension on the quality of spinal anaesthesia in patients undergoing proximal femoral nailing surgeries - randomized controlled study.

Introduction: Epidural volume extension is technique aiming to mitigate spinal anaesthesia induced hypotension, by reducing the dose of local anaesthetics. The present study was executed to determine the effect of epidural volume extension subarachnoid block with 0.5% hyperbaric bupivacaine in patients undergoing proximal femoral nailing (PFN) regarding characteristics of sensory-motor block and postoperative analgesia.

The impact of Lewis acid variation on reactions with di--butyl diazo diesters.

Reactions of (BuOCN) with Lewis acids and FLPs have previously been shown to prompt the formation of diazene compounds. In this work, we show that the reaction of (BuOCN) with 9-BBN leads to a bicyclic heterocyclic product (BuOCO(BBN)CN)1. In contrast, the reactions of (BuOCN) with BF or [EtSi][B(CF)] lead to the isolation of [BuNHNHBu][BF] 2 and [BuN(H)NBu][B(CF)] 3, respectively.

Comparative evaluation of lignocaine nebulization with and without dexmedetomidine for flexible videoendoscopic guided awake nasal intubation for general anaesthesia.

Background And Aims: Awake fibreoptic intubation is considered a safe approach in airway management of a patient with difficult airway. Awake fibreoptic endoscopy needs appropriate anaesthesia of airway to suppress airway reflexes and prevent discomfort. We planned this study to evaluate effect of adding dexmedetomidine to lignocaine nebulization on conditions for awake videoendoscopic intubation.
