Title: Association between variations in the combination of lidocaine and arterial spasm, in procedures for radial access


INTRODUCTION: Currently in endovascular procedures, mainly coronary ones, the use of radial arterial access predominates. Moving more and more to the femoral access which is only reserved for specific indications or the impossibility of doing it by the first. One of the complications that the operator most frequently faces when handling the radial artery is spasm, making it very difficult and sometimes preventing the completion of the diagnostic study or therapeutic procedure.
MATERIALS AND METHODS: With this cross-sectional, observational analytical study we wanted to propose as the main objective to evaluate the efficacy and safety of lidocaine and its combination with nitroglycerin and diltiazem, to reduce radial spasm in coronary procedures, of the lower limbs and neck vessels. Secondary objectives were to analyze the association between spasm and other complications, the combination of lidocaine, age, sex, BMI, cardiovascular risk factors, comorbidities, and prior drug treatment.
RESULTS: Of the complications described, arterial spam only appeared in 21 patients (25.3%), more frequent in women than men 30.8% and 20.5%, respectively. Regarding the most affected age group, it was> 70 years (33.3%) and the majority were overweight (66.7%). The group with the least spasm was the Lidocaine + Nitroglycerin group (n = 3, 10.7% 0.01> p <0.05), followed by the Lidocaine + Diltiazem group (n = 9 32.1% p> 0.10) compared to lidocaine (33.3%).
More than 50% had regular ACEI and / or AIIRA medication, Aspirin, Clopidogrel, Statins and beta-blockers; the most frequent comorbidity was peripheral disease and cardiovascular risk factors, hypertension, dyslipidemia, and sedentary lifestyle.
CONCLUSION: The appearance of radial arterial spasm with the use of Lidocaine 2% + Nitroglycerin 200 mcg, subcutaneous at the level of the radial canal, is less than that registered with the administration of Lidocaine alone and Lidocaine + Diltiazem, without adverse effects or others complications
