Safety/Efficacy Study of Local Anesthetic Prior to Femoral Artery Sheath Removal

Randomized Controlled Trial Examining the Effect of Subcutaneous Xylocaine 2% on the Incidence of Vasovagal Reactions and Pain Intensity During Femoral Artery Sheath Removal.

This randomized controlled trial will examine the impact of local anesthetic on the frequency of vasovagal reactions and the patients perception of pain during femoral arterial sheath removal after percutaneous coronary intervention.

Patients undergoing percutaneous coronary intervention(PCI) will be randomized to receive subcutaneous local anesthetic (Lidocaine 2% without epinephrine)or no local prior to removal of femoral arterial sheath. They will be assessed for vasovagal reactions and pain intensity during the sheath removal.The incidence of vasovagal reactions and pain intensity scores will be compared between the groups. 200 patients will be enrolled over the course of 2 months.

Inclusion Criteria:

• Percutaneous Coronary Intervention

Exclusion Criteria:

• Less than 18 years old
• Emergency procedure
• Transferred out of heart investigation unit prior to sheath removal

• Closure devise
• Venous sheath insitu
• Intra-aortic balloon pump insitu
• Tranvenous pacing
• Mechanical ventilation
• Cognitive impairment
