The Application Effect of Ultrasound-guided Intercostal Nerve Block Com-bined with General Anesthesia in Geriatric Thoracic Surgery
Objective To explore the effect of general anesthesia combined with ultrasound-guided intercostal nerve block intervention in geriatric thoracic surgery.Methods Sixty elderly thoracic surgery patients admitted to Dongfang Hospital of Lianyungang City from July 2022 to October 2023 were selected as the study objects.They were divided into two groups by random number table method.The control group(n=30)was given general anesthesia;the observa-tion group(n=30)was additionally treated with ultrasound-guided descending intercostal nerve block intervention.The hemodynamic level,plasma cortisol and angiotensin Ⅱ,postoperative pain were compared between the two groups before and after anesthesia.Results After anesthesia,systolic blood pressure(142.35±10.54)mmHg,diastolic blood pressure(60.24±4.86)mmHg and heart rate(68.14±6.57)times/min in observation group were better than those in control group(151.74±12.29)mmHg,(67.15±5.41)mmHg,(73.40±6.35)times/min,and the differences were statisti-cally significant(t=3.177,5.204,3.153,all P<0.05).The levels of cortisol and angiotensin Ⅱ in observation group were lower than those in control group,and the differences were statistically significant(both P<0.05).The pain scores at rest and activity in the observation group were lower than those in the control group,and the differences were statis-tically significant(both P<0.05).Conclusion For elderly thoracic surgery patients,the general anesthesia with ultrasound-guided intercostal nerve block intervention can maintain hemodynamic stabilization and reduce stress re-sponse and postoperative pain.
