Abstract:
Objective To study the value of ropivacaine combined with dexmedetomidine for deep plane block anesthesia of anterior serratus muscle in breast mass resection.Methods A total of 88 patients who underwent elective breast mass resection in Rugao People's Hospital from February 2020 to February 2022 were selected and divided into two groups according to the random number table,with 44 patients in each group.Before induction of anesthesia,deep plane block anesthesia of anterior serratus muscle was performed in both groups.Ropivacaine was used in group R,and ropivacaine and dexmedetomidine were used in group RD.Intraoperative propofol dosage,intraoperative remifentanil dosage,sufentanil dosage within 24 hours after operation,and extubation time were compared between the two groups.Mean arterial pressure(MAP)and heart rate(HR)were recorded before anesthesia(T0),during skin incision(T1),at 15 minutes of surgery(T2),and at 30 minutes of surgery(T3).Visual analog scale(VAS)score was recorded at 4,8,12 and 24 hours after surgery.The adverse reactions were observed.Results The dosages of propofol,remifentanil and sufentanil in the RD group were less than those in the R group,and the extubation time of the RD group was shorter than that of the R group(P<0.05).MAP and HR increased first and then decreased with the operation time in both groups(P<0.05).MAP and HR in the RD group were lower than those in the R group at T1,T2 and T3(P<0.05).Postoperative VAS scores of the two groups increased first and then decreased with time(P<0.05).The VAS scores in the RD group were lower than those in the R group 4,8,12 and 24 hours after surgery(P<0.05).The incidence of adverse reactions in the RD group was lower than that in the R group(P<0.05).Conclusion Ropivacaine combined with dexmedetomidine for deep plane block of anterior serratus muscle in breast mass resection can reduce the use of anesthetics,maintain the hemodynamic stability,and reduce the degree of postoperative pain.It has high safety.
