Radial Artery Access - Vasodilator Cocktail

Vasodilator Cocktail for radial artery access:

Nicardipine 200 mcg in 2 ml
1% Lidocaine 1 ml
3-5K of Heparin
+ patient's blood

Infuse slowly as soon as access is obtained.

(Do some folks add Nitroglycerin to this cocktail?)

Terumo sheath - hydrophilic coating helps.
Propafol can be used as a lubricant.
Sterile mineral oil - if the pharmacy has it - can also be used as lubricant.

Prevalence of late hypertension after coarctation repair - Age at operation

n=176 consecutive patients
Median f-up = 7.5 yrs.
Mortality - 0% for isolated coarctation (n=116), 7.4% for coarctation associated with other anomalies.
Seirafi et al.Ann Thoracic Surg 1998;66:1378-82.

Age at repair was not significant risk factor in another study: Hager et al. JTCVS 2007;134:738-45. n=405, Surgical era 1974-2000.
