Abstract
Objective To observe the application effect of ultrasound-guided anterior serratus plane block and typeⅡ thoracic nerve block in general anesthesia for radical surgery for breast cancer.Methods A total of 70 patients with general anesthesia for radical mastectomy for breast cancer admitted to Zibo Maternal and Child Health Hospital from January 2023 to January 2024 were selected and divided into the control group and the observation group according to the random number table method,with 35 cases in each group.The control group did not receive nerve block before anesthesia,and the observation group received ultrasound-guided anterior serratus plane block and type Ⅱ thoracic nerve block before anesthesia.The Ramsay sedation scores at the time of entry(T0),during surgery(T1),at the end of surgery(T2),and 1 hour after surgery(T3),pain level(visual analogue scale[VAS])before surgery and postoperative 6,12,and 24 hours,awakening time,extubation time,and incidence of adverse reactions were compared between the two groups.Results There were no statistically significant differences in Ramsay sedation scores between the two groups at T0 and T3(P>0.05).At T1 and T2,the Ramsay sedation scores in the observation group were higher than those in the control group(P<0.05).There was no statistically significant difference in awakening time and extubation time between the two groups(P>0.05).After 6,12,and 24 hours postoperatively,the VAS scores in the observation group were lower than those in the control group(P<0.05).At 12 hours postoperatively,both groups had lower VAS scores compared to before surgery and postoperative 6 hours(P<0.05).At 24 hours postoperatively,both groups had lower VAS scores compared to before surgery,postoperative 6 hours,and postoperative 12 hours(P<0.05).The total incidence of adverse reactions in the observation group was lower than that in the control group(P<0.05).Conclusion The ultrasound-guided anterior serratus plane block and typeⅡ thoracic nerve block in general anesthesia for breast cancer for radical surgery has a more positive effect,which can effectively promote sedation effect,improve pain,and reduce adverse reactions.关键词
