Clinical study of Arteriovenous needle used in rescuing patients with hemorrhagic shock / 中国基层医药

ABSTRACT

Objective To evaluate the clinical value of subclavian vein puncture with 16 G arteriovenous indwelling needle for emergency treatment of hemorrhagic shock,so as to provide a new approach for the rapid establishment of deep venous passage.Methods 80 patients with acute hemorrhagic shock were randomly divided into patients with arteriovenous indwelling needle group (catheter group) and conventional guide wire deep vein puncture group(routine puncture group),40 cases in each group.The two groups were treated with supraclavicular subclavian vein puncture.The operation time,success rate of the first puncture,puncture times and rehydration rate,incidence of complications were observed in the two groups.Results The operation time of indwelling needle group was (62 ±22)s,which was significantly shorter than (672 ± 178)s of the conventional puncture group,there was significant difference between the two groups (t =15.062,P =0.000).The first time success rate of puncture in the indwelling needle group was 70％ (28 cases),which in the conventional group was 80％ (32 cases),the difference was not statistically significant(x2 =1.067,P =0.439),all patients were in 3 attempts in successful puncture.The velocity of infusion of 500 mL hydroxyethyl starch in the indwelling needle group was (198 ± 51)s,which was better than (456 ± 86)s in the conventional puncture group,the difference between the two groups was statistically significant (t =9.318,P =0.000).The two groups had no deep vein puncture related complications.Conclusion Arteriovenous indwelling needle by supraclavicular subclavian vein puncture with conventional guide wire supraclavicular subclavian vein puncture catheter can be used for emergency treatment of hemorrhagic shock,but the indwelling needle group in the operation time and velocity is superior to conventional guide wire group,more suitable for the rescue of patients with acute hemorrhagic shock time is pressing,stay with stable circulation can be through the guide wire inserted catheter indwelling subclavian vein catheter.
