Comparison between two protocols for deflation of the TR band following coronary procedures via the radial route.

ABSTRACT: Aim:Coronary interventions are increasingly being performed via the radial rather than femoral route because of the lower complication rate. Compression devices such as the TR band are used to achieve hemostasis after the procedure. At present, there are no clear protocols for the deflation of the band. In this study we compared two protocols (early deflation with increased intervals vs. late deflation with smaller intervals) in terms of total time to band removal and complications, and patient and staff satisfaction. Methods:All patients who underwent a transradial coronary procedure and had a TR band fitted were enrolled into the study. The TR band was applied using the patent hemostasis method (2 ml air pushed in after the radial pulse appears on pulse oximetry after full occlusion with 16 ml air). Patients were randomly assigned to either protocol. Protocol 1 involved removal of 2 ml of air starting 1 hour after the sheath removal and then removal of 2 ml every 30 minutes until the band came off. Protocol 2 involved removal of 4 ml of air 2 hours after the sheath removal and then further 4 ml of air every 15 minutes until the band came off. Patient and staff satisfaction was measured with a visual analogue scale. Results:A total of 174 patients were recruited (mean age, 60 ± 11 years; 127 male, 47 female). The baseline characteristics including total heparin dose and type of procedure, in the two arms were the same. Protocol 2 (n = 84) was associated with a significantly lower time to TR band removal as compared to protocol 1 (n = 90; 201 ± 43 min vs. 274 ± 54 min; p < 0.001). There was no difference in complications such as bleeding or hematoma formation between the two groups. Patient satisfaction was the same between the two groups. However, the staff preferred protocol 1 (p = 0.01). Conclusion:A protocol of delayed initiation of TR band deflation followed by quick deflations is associated with a lower time to band removal with no increase in bleeding complications or patient satisfaction. However, the staff preferred longer intervals between deflations.

Project description:Background:Studies have demonstrated that female sex is an adverse risk factor in CABG. The primary aim of this study was to determine whether the radial artery (RA) was associated with reduced angiographic occlusion compared to the saphenous vein graft (SVG) stratified by sex in the multi-centered Radial Artery Patency Study (NCT00187356). Methods:Between 1996-2001, 529 patients less than 80 years, with graftable triple-vessel disease underwent isolated CABG across 11 centers with late angiographic and clinical follow-up. The primary objective was to compare complete occlusion of RA and SVG with respect to sex. The secondary objective was to determine cumulative patency of both grafts along with predictors of late graft occlusion stratified by sex. The additional objective was to compare major adverse cardiac events (MACE, defined as cardiac mortality, myocardial infarction or re-intervention) between women and men. Results:Of the 529 enrolled patients (13.4% women), 269 (women: n=41, 15.2%) underwent late angiography at a mean of 7.7±1.5 years after CABG. Women were older (64.1±6.7 versus 59.1±8.0 years, P<0.01) with a higher rate of diabetes (43.9% versus 28.5%, P=0.05). Smoking history was less common (48.8% versus 75.4%, P<0.01) while the mean number of grafts per patient were similar (women: 3.8±0.7, men: 3.8±0.6, P=0.65). RA occlusions were lower than SVG in women (RA: 9.8%, SVG: 26.8%, P=0.05) and in men (RA: 8.8%, SVG: 17.1%, P=0.01). The rate of RA and SVG occlusion was not statistically different between women and men, and cumulative patency curves were also similar between sexes for the RA and study SVG. Multivariable modeling showed that having a RA (versus SVG) was protective in women [odds ratio (OR) 0.15, P=0.04] and men: (OR 0.49, P=0.02). MACE (P=0.15) and event-free cardiac survival (log-rank P=0.14) were similar between women and men. Conclusions:Radial arteries are protective in both women and men with comparable burden of coronary disease and revascularization.
