Anesthetic Effect of Different Concentrations of Ropivacaine for Ultrasound-guided Interscalene Brachial Plexus Block
Objective To analyze the anesthetic effects of different concentrations of ropivacaine for ultrasound-guided interscalene brachial plexus block.Methods A total of 80 patients who received ultrasound-guided intersca-lene brachial plexus block anesthesia in Luoyuan County Hospital of Fujian Province from August 2021 to August 2023 were randomly selected as the research objects.According to the different concentrations of ropivacaine,they were divided into control group(0.3%ropivacaine)and observation group(0.5%ropivacaine),with 40 cases in each group.The changes of vital signs,anesthesia index levels and incidence of adverse reactions were compared between the two groups.Results There was no statistically significant difference in mean arterial pressure and heart rate be-tween the two groups(both P＞0.05).The onset time of anesthesia was(11.20±1.38)min,duration of analgesia was(9.57±1.53)h,onset time of motor block was(8.10±0.59)min,and sensory recovery time was(5.51±0.44)h in the ob-servation group,which were better than those in the control group(t=9.464,5.074,6.340,6.359,all P＜0.05).There was no statistically significant difference in the total incidence of adverse reactions between the two groups(P＞0.05).Conclusion The anesthetic effect of 0.5%ropivacaine is better,the pain block effect is good,the anesthetic effect is fast,and the adverse reactions are not increased,and the impact on vital signs is small.
