Ultrasonic Technology In Clinical Application Of The ICU In Shock Patients For Radial Artery Puncture

Objective:To observe the effects of the application of ultrasound technology in out of plane-orientation and following in plane-guide tube in ICU patients with shock and radial artery puncture,thus to elucidate the safety of puncture tube by using this strategy.Methods:To select 88 cases of ICU shock were randomly divided into touch positioning group(control group)and the ultrasound group(experimental group).Both groups were treated equally with intravenous sedation and analgesia.The traditional radial artery cannulation by method of touch pulsation was performed for touch positioning group.While for the ultrasound group,the radial artery cannulation was performed by first plane-positioning and plane-guide methods after checking position of radial artery,trajectory and surrounding tissues by using ultrasound.Data were recorded and compared between the two groups as the success rate and failure rate(punctured three times without success)of puncture,puncture duration,complications and time to achieve the early goal directed therapy(EGDT)target,further to elucidate the roles of the ultrasonic technology in guiding first out of plane-orientation and plane-guide tube in radial artery puncture in ICU shock patients and its impacts on treatments.Results:(1)Puncture success rate of the ultrasound group(80%)is significant higher than what of touch positioning group(42%)(P<0.05).(2)Catheterization time of the ultrasound group(8.77 ± 6.33 seconds)was significant shorter than what of touch positioning group((28.7 ±26.33 seconds)(P<0.01).(3)Hematoma and puncture oozing ocurrences of the ultrasound group(2.5%and 5%)were significant less than what of touch positioning group(20%and 32.5%)(P<0.05).(4)Treatment time to reach the EGDT of the ultrasound group(306.73 ±39.98 minutes)was significant shorter that what of touch positioning group(356.75 ±40.97 minutes)(P<0.01).Conclusion:Compared to the traditional method,the application of ultrasound technology in first positioning and orientation outside and plane guide tube for radial artery cannulation in shock patients can increase success rate of first puncture,decrease puncture duration,reduce complications and thus shorten the time to achieve EGDT.
