Comparing intravenous lidocaine and pethidine for pain management in emergency department patients with femoral bone fracture: a randomized controlled trial.

Background: Intravenous lidocaine has shown promise as an effective analgesic in various clinical settings, but its utility for pain management in emergency departments, especially for bone fractures, remains relatively understudied.

Objective: This study compared intravenous lidocaine to pethidine for femoral bone fracture pain management.

Methods: This double-blind, randomized, controlled clinical trial was conducted in the emergency department of AJA University of Medical Sciences affiliated hospitals.

A new azo-azomethine sensor for detection of CN and AcO- anions: Highly selective chemosensor for naked eye detection of sodium diclofenac.

New azo-azomethine sensor, HL, has been synthesized and characterized using standard spectroscopic methods. HL was found to sense CN and AcO in DMSO and semi-aqueous media over other anions such as F-, Cl-, Br-, I-, HPO- and HSO-. The anions recognition ability of HL was also evaluated using UV-Vis absorption and H NMR spectroscopy.
