Effect analysis of ultrasound-guided lumbar paravertebral nerve block and light general anesthesia in elderly patients undergoing total hip arthroplasty
Objective To analyze the application effect of ultrasound-guided lumbar paravertebral nerve block and light general anesthesia in elderly patients undergoing total hip arthroplasty(THA).Methods 86 elderly patients with THA were selected and divided into a control group and an observation group by random number table method,with 43 cases in each group.The control group was given total intravenous anesthesia,and the observation group was given ultrasound-guided lumbar paravertebral nerve block+light general anesthesia.The anesthesia recovery time,hemodynamic indices,postoperative numerical raing scale(NRS)score and adverse reactions were compared between the two groups.Results In the observation group,the time to open the eyes on call was(15.87±2.44)min,the time to clench the fist on call was(20.18±2.15)min,the extubation time was(21.38±4.19)min,and the wake up time was(17.91±3.23)min,which were shorter than(20.26±3.58),(24.65±3.25),(28.26±5.77),and(30.06±4.72)min in the control group(P<0.05).At 10,30 min after anesthesia and at the end of the operation,the heart rate of the observation group were(75.12±5.42),(74.24±5.71),and(88.12±5.51)beats/min,and the mean arterial pressure were(86.35±4.55),(83.42±4.35),and(105.36±6.18)mm Hg(1 mm Hg=0.133 kPa);in the control group,the heart rate were(85.45±5.25),(82.26±6.31),and(93.45±5.26)beats/min,and the mean arterial pressure were(91.28±6.31),(87.85±6.42),and(113.62±6.57)mm Hg.At 10,30 min after anesthesia and at the end of the operation,the heart rate and mean arterial pressure in the observation group were lower than those in the control group(P<0.05).At 10,30 and 60 min after operation,the NRS scores of the observation group were(2.25±0.28),(3.16±0.48)and(3.47±0.61)points,which were lower than(3.10±0.45),(4.05±0.77)and(4.78±0.96)points of the control group(P<0.05).The incidence rate of perianesthesia adverse reactions of 4.65%in the observation group was lower than 18.60%in the control group(P<0.05).Conclusion Ultrasound-guided lumbar paravertebral nerve block+light general anesthesia in elderly patients with THA can stabilize hemodynamic indices,shorten wake-up time,reduce postoperative pain,and has fewer adverse reactions.
