Multicomponent solution for local anaesthesia in operations on extremities

The analysis of the results of local anaesthesia (LA) in 89 patients aged 18 to 68 years with trauma and diseases of extremities has been carried out. The efficiency of perineural injected multicomponent solution of clonidine added to conventional mixture of lidocaine and phentanyl has been assessed. The multicomponent method has significantly prolonged the duration of local anaesthesia of 1% lidocaine solution providing reliable anaesthesia of plexus and peripheral nerves alongside the sufficient regional myoplegia and prolonged postoperative anesthetization. When there is no need of deep myoplegia it allows to lower the concentration of lidocaine solution twofold, maintaining its efficiency, and to realize local anaesthesia of patients with high risk.
