Prolonged Suppression of Postincisional Pain by a Slow-release Formulation of Lidocaine

Anesthesiology, 12/24/2010

Implants of slow–release lidocaine formulations are most effective against postincisional pain when placed at the ipsilateral nerve innervating the area of incision. Contralateral nerve implants are somewhat less effective, probably acting by releasing lidocaine into the systemic circulation. There appears to be a differential role of central sensitization between postincisional allodynia and hyperalgesia.
