Objective:To explore the effectiveness of using B-ultrasound guided indwelling needle puncture technology in patients with difficulty in enhanced CT puncture.Methods:A retrospective study was conducted on 80 patients with difficulty in performing enhanced CT puncture in our hospital from February 2020 to February 2023.According to the puncture method,they were divided into two groups:the B-ultrasound guided indwelling needle puncture technique group(B-ultrasound guided group)and the conventional puncture group,with 40 patients in each group.Statistical analysis was conducted on the success of one-time catheterization,unplanned extubation,puncture frequency,operation time,indwelling needle retention time,consumables cost,enhanced CT image quality,incidence of adverse reactions,and satisfaction of two groups.Results:The success rate of one-time catheterization in the B-ultrasound guided group was higher than that in the conventional puncture group(P<0.05),and the unplanned extubation rate was lower than that in the conventional puncture group(P<0.05).The number of punctures in the B-ultrasound guided group was less than that in the conventional puncture group(P<0.05),the operation time and indwelling needle retention time were shorter than those in the conventional puncture group(P<0.05),and the consumables cost was lower than that in the conventional puncture group(P<0.05).The excellent rate of enhanced CT image quality in the B-ultrasound guided group was 95.00%(38/40)higher than that in the conventional puncture group 75.00%(30/40),and the difference was statistically significant(χ2=6.275,P<0.05).The incidence of adverse reactions in the B-ultrasound guided group was 7.50%(3/40)lower than that in the conventional puncture group 25.00%(10/40),and the difference was statistically significant(χ 2=4.501,P<0.05).The satisfaction rate of patients in the B-ultrasound guided group was 97.50%(39/40)higher than that in the conventional puncture group 80.00%(32/40),and the difference was statistically significant(χ2=4.507,P<0.05).Conclusion:The application of B-ultrasound guided indwelling needle puncture technology in patients with difficulty in enhanced CT puncture is more effective than conventional puncture.
