Use of Ultrasound in arterial line insertion

Three Part Question

In patients requiring [arterial line insertion] does[the use of ultrasound ] when compared to the manual palpation method lead to [improved success in catheter placement]?

Clinical Scenario

A septic hypotensive patient required an arterial line for early goal directed therapy but bilateral radial pulses were weak and multiple attempts were unsuccessful. A radial artery catheter was eventually secured under ultrasound guidance.

Search Strategy

Healthcare Database Advanced Search(NHS evidence) MEDLINE & EMBASE [(arter* ADJ cathet*).ti,ab OR (arter* ADJ cannula*).ti,ab] AND [exp (*ULTRASONOGRAPHY, INTERVENTIONAL/) OR (sonograph*.ti,ab) OR (doppler*.ti,ab)] [Limit to: Publication Year 1950-Current and Humans and English Language]

For EMBASE [exp (*ULTRASOUND) OR (sonograph*.ti,ab) OR (doppler*.ti,ab)] was used



Further searches were done via the Cochrane Database ;Google Scholar. A hand search of papers was also conducted.

Search Outcome

19 relevant papers were found. 13 were case series/case reports describing the use of ultrasound in arterial line insertion and 6 papers specifically compared the use of ultrasound with the manual palpation method.

166 patients with a palpable radial artery(RA) pulse undergoing RA cannulation prior to elective surgery randomised to two groups 1.RA cannulated by using a doppler ultrasound detector (audio) to identify site and non touch insertion of catheter 2.RA cannulated by manual palpation methodprospective; randomised; non blindedsuccess defined as cannulation at first attemptno difference found between the two groupssmall numbers of elective surgery patients in each group; no mention of blinding of data analysis

69 patients elective surgery patients underwent radial artery cannulation by anaesthetists either by manual palpation method or with the use of a 4MHz US transducerprospective; randomised; non blindednumber of attempts fewer attempts in US group (p=0.003)small numbers; endpoint for failure not clear; crossover data between groups not included in analysis; level of experience with ultrasound not controlled for in operators
time for succesful attemptslonger in US group (p=0.001)
success at first attempthigher rate in US group (p=0.03)
number of cannulae usedfewer cannulae used in US group (p=0.001)

112 patients undergoing femoral artery (FA) cannulation for angiography by 2 interventional radiologists divided into 2 groups-FA puncture via palpation method or with the use of 7.5MHz linear US probe on a mechanical swivel armprospective;randomised;non blindednumber of attempts for successful placement of catheterno difference between groupssmall numbers; equipment not generalisable to the emergency department
patients with leg circumference greater than 60cm at puncture site (n=23)fewer attempts (p<0.001) and less time (p<0.04) in US group
patients with weak arterial pulses (n=42)fewer attempts(p<0.05) and less time( p<0.04) in US group
complicationsno difference between groups
