Comparison of lumbar plexus-sciatic nerve block and spinal anesthesia on elderly patients with knee joint sur-gery during the perioperative period / 局解手术学杂志

ABSTRACT

Objective To compare and analyze the clinical application of lumbar plexus combined with sciatic nerve block and spinal anesthesia for elderly patients with knee joint surgery.Methods A total of 77 elderly patients with ASAⅠ ~Ⅲ undergoing single knee re-placement surgery were randomly divided into combined group which recieved lumbar plexus combined with sciatic nerve block and spinal an-esthesia group.The baseline values,blood pressure and heart rate at multiple time points,the block area and duration,the volume of intraoper-ative fluid,and other indexes of adverse reaction were observed.Results The MAP,SBP and DBP in the spinal anesthesia group after the op-eration have changed significantly at the time of T1,T2 and T3.The operating of anesthesia in the combined group was shorter than that of spi-nal anesthesia group.The rate of adverse reactions in combined group was significantly lower than that inspinal anesthesia group.Conclusion The spinal anesthesia can be satisfied for operation requirements,but it will cause the unstable circulation and varied adverse reactions.Lum-bar plexus combined with sciatic nerve block is safe and effective with less adverse reactions,less disturbance of hemodynamics,which is much better for the old or the patients with coagulation abnormalities combined heart and lung disease.
