ANESTHESIA FOR CAROTID STENTS Anesthetic Choice: MAC: -Surgeons have requested minimal Versed or narcotics at beginning of case! -These patients will need to be awake during the critical parts of the case, so these pts are more lightly sedated. -PROPOFOL ONLY IN BEGINNING OF CASE -Use propofol bolus injections and infusion for arterial line insertion, Foley insertion, and groin access. Once groin access is obtained, the surgeon will want to have patient breath hold for arteriograms, therefore the patient needs to be awake and cooperative. Surgeon has requested that no sedation be given at the end of the case after deployment of the stent. Research is showing that sedation at the end of the case can be contributory to hypotension. For this reason if you feel the patient needs sedation or is in pain, please evaluate each case individually with surgeon regarding analgesia or possible sedation. Position: Both arms tucked, in case need to open Place “oogah” horn in hand opposite operative side, (wrap in with kerlix so pt doesn’t drop it) patient can then squeeze it on command Make sure all wires and nasal cannula tubing out of C-Arm beam Be sure metal gown snaps removed Lines: -need 2 IV -arterial line Revised 6/05 Brewer Ragab Pharmacology: -Heparin, based on surgeon and ACT -Phenlyephrine(bolus and infusion)—necessary with balloon angioplasty, preferred over Dopamine by surgeon during case. If further support needed in PACU, will switch to Dopamine. -Robinul/Atropine REQUIRED before balloon angioplasty (Robinul 0.2-0.4mg: Atropine 0.4-0.8mg) Tips: IN ROOM 26, PLEASE HAVE ALL WIRES AND LINES OFF RIGHT SHOULDER, OR USE THE FOOT MOUNTED MONITORING MODULE ON AVANCE MACHINE. -Access for sheath and catheters is usually groin, may be brachial. CONT’D. -Heparin dosing per surgeon, with frequent ACT, at least q20-30 min -MUST USE ANTICHOLINERGIC PRIOR TO BALLOON ANGIOPLASTY!!! Will see profound bradycardia to asystole with balloon if not pre-treated. *Avoid beta blockers if at all possible, will enhance this problem* -Need patient normotensive or a little above normal before balloon angio to assure collateral circulation. After balloon angio, may see Profound Hypotension therefore pretreatment with phenlyephrine bolus right before angio helpful -Will do balloon angioplasty of carotid 1-2 times, during this time, patient is VERY uncomfortable, need to warn patient before balloon inflated, and help them hold head still. -Following angioplasty will have patient squeeze horn in contralateral hand, and wiggle toes as well as assess orientation -Will shoot MedRad automatic contrast injector, during these angiographies, important that patient not talk, breathe, or move, that’s one reason why they want patient awake Revised 6/05 Brewer Ragab -Be aware that there can be significant blood loss at groin site—may be hidden in drapes. If hypotension does not respond to vasopressors, consider anemia -Rare instances of Extreme hypertension may require NTG gtt Revised 6/05 Brewer Ragab
