An interventional study of ulnar artery compression device and radial artery compression device guided with plysthmography in CARDIAC CATHETRIZATION, sponsored by Assiut University. Status unknown. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2017-06-09.
Sponsored by Assiut University · Not applicable, Interventional, and Treatment
Data from literature: transradial access failure sometimes occurs due to inability to cannulate the radial artery due to radial artery spasm1 causing severe difficulties in manipulation of the guide wires and catheters along the tortuous pathways of the arteries. both mechanical stimuli and circulating catecholamines through activation of α1-adrenoreceptors, causing smooth muscle cell contraction \& radial artery spasm

Exclusion Criteria:
Device: ulnar artery compression device · Device: radial artery compression device
Device: radial artery compression device guided with plysthmography
Device: radial artery compression device
a radial compression device will be applied at the access site. another closure device will be used for ipsilateral ulnar artery compression for 1-hour duration in order to increase peak velocity blood flow into the radi¬al artery. neither pulse oxymetry nor duplex ultrasonography will be performed in case of ulnar artery compression. after ulnar artery compression, the initial compression of the radial artery will be reduced by letting up the pressure until bleeding will be seen and then adding minimal pressure whenever needed in order to maintain radial artery patency.
a radial compression device will be applied at the access site. A pulse oximeter sensor was placed over the index finger. Transient ipsilateral ulnar artery will be occluded manually to evaluate the status of radial artery patency by plethysmography (digital pulse analysis), and if there's lack of signal, the process of deflation and reinflation of the radial artery device's bladder will be repeated over the next 15 min to attempt re-establishment of antegrade radial artery flow without affecting hemostasis
patients undergo the conventional hemostasis compression by using a radial compression device applied at the access site.
The percentage of occurrence of radial artery occlusion
the assessment will be done after compression device removal guided by duplex post trans-radial cardiac catheterization.
