Is Conventional TR Band Deflation Protocol Inferior to Internationally Developed TR Band Removal Protocol in Reducing Occurrence of Radial Artery Occlusion
September 26, 2017 updated by: Nasir Rahman, Aga Khan University
Coronary artery disease (CAD) is one of the major health concerns among other non-communicable diseases globally.
Cardiac catheterization is a diagnostic gold standard to determine the extent of disease in coronary arteries due to atherosclerosis.
Among the two approaches for cardiac catheterization, trans-radial approach has gained more popularity than conventional trans-femoral approach over the past decade with availability of compression devices for radial artery that assures lesser risk of bleeding and hematoma and has translated into increased patient comfort and early mobility post procedure.
Radial artery occlusion is a common complication of trans-radial procedures often ignored by the operator after procedure due to dual blood supply by ulnar artery.
Although clinically silent usually, it necessitate the need of monitoring radial artery for patency because of risk of limited trans-radial access later.Reportedly, RAO occurs in about 10% of cardiac catheterizations.
, compression devices applied after sheath removal may be a contributing factor to radial artery occlusion because of selective pressure for extended time duration (3-4 hours).
Various protocols have been developed to remove TR band by different institutions across the globe and have been tested to assess post procedure complications.
To the best of what we know, there exists no standard protocol to deflate TR band.
Also, the current protocol in practice at our institution has not been evaluated against other protocols that are followed in other institution across the globe claiming lesser post procedure complications.
Hence, our aim was to test through a randomized trial whether our hospital standard protocol is non-inferior to the existing international protocol of Cohen & Alfonso that promises lesser complication rate

Active Comparator: TR BAND Protocol A
In this group, air removal from TR band was initiated after 2 hours of TR band application.
3 ml of air was removed periodically at an interval of 15 minutes until all the air is eliminated from the band.
In case of bleeding or hematoma while deflating air, 4 ml of air was re-injected and observed for 30 minutes until next attempt was made to deflate the band.
The data including the attempts made at deflating TR band, time and amount of air injected along with the response to each deflation i.e. occurrence of bleeding or hematoma was noted down in the proforma

Active Comparator: TR BAND PROTOCOL B
In this group deflation was initiated after 2 hours of TR band application as described by Cohen and Alfonso.
[6] 5 ml of air was deflated at first attempt.
Next attempt was carried out after 15 minutes in which further 5 ml was removed.
After 15 minutes, the remaining 2 ml of air was released from the band.
In case of bleeding or hematoma at any attempt, 6 ml air was re-injected and interval for 15 minutes taken to attempt further air deflation.
All the attempts and its response were recorded in the proforma filled out by the assessor.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Radial artery occlusion (RAO)
Time Frame: from TR band removal upto 24 hours of hospital stay of the patient
|
Radial artery patency was assessed in both groups by ultrasound doppler and bed side plethysmographic waveforms
|
from TR band removal upto 24 hours of hospital stay of the patient
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Hematoma
Time Frame: from TR band removal upto 24 hours of hospital stay of the patient
|
Patients in both arms were assessed for the presence of hematoma in the cannulated arm used for the angiography before and after the TR band removal.
Hematoma were graded from grad 1-5 according to the extent of arm involvement as per standard EASY hematoma classification system.
|
from TR band removal upto 24 hours of hospital stay of the patient
|
Re bleed
Time Frame: from the time of TR band application, during its removal and upto 24 hours of hospital stay of the patient
|
patients in both arms were assessed for any sign of major or minor bleeding from the punctured site, such as oozing, frank bleeding which required extra pressure to apply on the site to control it, or required extra amount of air to be inflated to control it.
any such event was documented as Re bleed after the TR band application.
|
from the time of TR band application, during its removal and upto 24 hours of hospital stay of the patient
