Effect of ultrasound-guided quadratus lumborum block combined with nalbuphine on elderly patients undergoing THA
Objective:To investigate the effect of ultrasound-guided quadratus lumborum block combined with nalbuphine on elderly patients undergoing THA.Methods:Elderly patients who underwent THA were selected and randomly divided into two groups.After surgery,the treatment group received ultrasound-guided quadratus lumborum block,while the control group did not receive such block.The two groups were given multimodal analgesia with intravenous injection of nalbuphine(5mg)every 24 hours and nerve block.The situation of sedation and analgesia,motion of hip joint,and cognitive function were compared between groups.Results:Ramsay scores and VAS scores of the treatment group after surgery were lower than those of the control group(P<0.05).MMSE scoreof the treatment group at 48 h after surgery,and maximum range of flexion and range of abduction of hip joint were higher/greater compared to the control group(P<0.05).Conclusion:Ultrasound-guided quadratus lumborum block combined with nalbuphine can reduce Ramsay score and VAS score of elderly patients undergoing THA,improve their cognitive function and motion of hip joint.
