Effect of paravertebral nerve block on intraoperative blood flow,postoperative stress and rehabilitation quality of obese patients undergoing minimally invasive gastrectomy
Objective To analyze the influence of paravertebral nerve block on blood flow,postoperative stress and rehabilitation quality of obese patients undergoing minimally invasive gastrectomy.Methods One hundred and twenty-six obese patients undergoing minimally invasive gastrectomy in Peking University First Hospital Taiyuan Hospital from January 2022 to December 2023 were selected and randomly divided into observation group(n=63)and control group(n=63).The control group was anesthetized with epidural block,while the observation group was anesthetized with paravertebral nerve block.Both groups of operations were completed by the cooperation of the same medical team and anesthesia team.The operation and recovery,intraoperative hemodynamic changes,postoperative stress indexes and postoperative complication rate were compared between the two groups.Results The time of getting out of bed for the first time in the observation group was shorter than that in the control group(P<0.05).At the beginning of operation,30 min,60 min and after operation,MAP and HR in the observation group were lower than those in the control group(P<0.05).Epinephrine(E)and norepinephrine(NE)in the observation group were higher than those in the control group after operation,and dopamine was lower than that in the control group.E,NE and dopamine in the observation group were lower than those in the control group at 24 h after operation(P<0.05).The numeric rating scale(NRS)scores in the observation group were lower than those in the control group at 2 h,6 h,12 h and 24 h after operation(P<0.05).No complications such as abdominal infection,hematoma and nerve injury occurred in both groups after operation.Conclusion Compared with epidural block,paravertebral nerve block anesthesia can maintain the stability of blood flow and postoperative stress indexes in obese patients during minimally invasive gastrectomy,which is beneficial to relieve postoperative pain and improve the quality of rehabilitation.
