RESUMEN
ObjectiveTo observe the effect of nerve block combined with sequential analgesia in peri-operative knee arthroscopy.Methods Two hundred patients undergoing knee arthroscopy,were performed lumbar plexus and sciatic nerve block anesthesia by nerve stimulator with ultrasound guidance.Celecoxib was combined for sequential analgesia.The vital signs,the effect of anesthesia in the surgery,the duration of postoperative analgesia,and patient's satisfaction to analgesia were observed to evaluate the clinical effects.ResultsThe vital signs of the patients in the surgery were stable,the effect of anesthesia was good,180 cases of excellent,16 cases of good,4 cases of poor.The duration of postoperative analgesia was 6-10 (8.2 ± 0.5) h.Combined with sequential analgesia program,there was high patient's satisfaction [ excellent 75％ (150/200),good 10％ (20/200),general 10％ (20/200),poor 5％ ( 10/200 ) ].Conclusion The nerve block combined with sequential analgesia is safe and effective in knee arthroscopy,it achieves high patient's satisfaction,this maybe a routine in knee arthroscopy.
