<s>[INST] I am a heart patient undergone stent about 8 years back and very regularly visit narayana hrudalyala for periodic checkups. Now I have some dental problem and have gone to Narayana Hrudayala Dental centre at Rajajinagar. I need to undergo root canaling and Dr, Ramya who is attending me wants to have a clarification - as to if the local anesthisya that needs to be given i,e 2 ml solution NERVE BLOCK has to be given WITH OR WITHOUT ADRENALINE. Please clarify this. Thanks & Regards. S.Vasudevan - cell no. 0000 [/INST] Thanks for your query, I have gone through your query.The root canal treatment can be done under local anesthesia without adrenaline.The local anesthesia with adrenaline will result in vasoconstriction and increases the blood pressure so you can get it done under local anesthesia without adrenaline since you are a cardiac patient.Another possibility is you can also do RCT under local anesthesia with adrenaline if your blood pressure at the time of procedure should be within normal limits.To be on the safer side, get it done under local anesthesia without adrenaline.I hope my answer will help you, take care. </s>
