Ultrasound in brachial plexus block anesthesia application effect analysis / 中国基层医药

ABSTRACT

Objective To explore the application effect and safety of ultrasonic location in interscalene bra-chial plexus block anesthesia.Methods 100 cases with upper extremity orthopedic surgery patients were selected, according to the brachial plexus between the different positioning methods,they were divided into control group and observation group,50 cases in each group,the control group chose the traditional anatomical localization techniques, observation group interscalene under ultrasound guidance brachial plexus block,two groups of anesthesia were com-pared,block success rates and complications were observed.Results The block operation time,anesthesia onset time,duration of analgesia and anesthesia drug dosage of the observation group were (185.5 ±24.86)s,(11.55 ± 2.89)min,(11.42 ±2.39)min,(17.25 ±2.54)mL while the control group were (228.75 ±26.20)s,(16.05 ±4.66)min,(10.95 ±2.83)min,(19.50 ±2.79)mL,there was significant difference between two groups(t =18.34, 10.28,9.72,10.68,all P <0.05).the anesthesia success rate of the observation group was 98%,significantly higher than 88% of the control group,the difference between the two groups was statistically significant(χ2 =9.12,P <0.05).The incidence rate of complications in the observation group was 0,while the control group was 8%,two groups had significant difference in complication rate(χ2 =8.34,P <0.05).Conclusion Ultrasonic location in in-terscalene brachial plexus block anesthesia has a good clinical effect,with high safety,which is worthy of populariza-tion and application.
