Application effect observation of dexmedetomidine combined with interscalene brachial plexus and suprascapular nerve block anesthesia during shoulder arthroscopic surgery
Objective To observe the application effect of dexmedetomidine combined with interscalene brachial plexus and suprascapular nerve block anesthesia during shoulder arthroscopic surgery.Methods 120 patients who received shoulder arthroscopic surgery from January 2023 to January 2024 were enrolled in the study,and were divided into the combined group(n=60)and the reference group(n=60)by adopting the random number table method.The combined group was given dexmedetomidine combined with interscalene brachial plexus and suprascapular nerve block anesthesia,while the reference group received interscalene brachial plexus and suprascapular nerve block anesthesia.The surgery-related indicators were recorded,and the analgesic effect VAS,MAP,HR,SpO2,VCmax,FVC and FEV1/FVC were compared at different time points.Adverse reactions of patients were recorded.Results At the end of surgery and at 30 min and 6 h after surgery,there was no statistical significance in VAS score between groups(P＞0.05).At 12 h,24 h and 48 h after surgery,VAS score was significantly lower in combined group than that in reference group(P＜0.05).At 10 min and 30 min after induction and at the end of surgery,the MAP,HR and SpO2 in both groups were lower than those before surgery,and the combined group had higher MAP,HR and SpO2(P＜0.05).The VCmax,FVC and FEV1/FVC in both groups at 24 h after surgery were lower than those before surgery,and the indicators in the combined group were higher than those in the reference group(P＜0.05).The incidence rates of adverse reactions in combined group were significantly lower than those in reference group(P＜0.05).Conclusion For patients undergoing shoulder arthroscopic surgery,interscalene brachial plexus and suprascapular nerve block combined with dexmedetomidine can prolong postoperative analgesic time,reduce pain caused by invasive procedures,and lower the incidence rates of adverse reactions,and it has a protective effect on lung function.
