![]() Push the tip of the pacer wire through the diaphragm into the cordis. You will extend the sheath to cover the full length of the pacer, allowing future sterile adjustments. At some point, you will need to clip the large white proximal hub of the sheath onto the cordis. You can leave it all scrunched up for now, but if you don’t put it on now, you won’t be able to later. Be sure to put the swan sheath on the pacer before inserting it into the cordis. The hub on the cordis has a diaphragm built-in, so you don’t need to add a blue cap and blood won’t gush out at you. Once in place, the blue dilator is unscrewed and withdrawn, leaving the catheter. Inserting the Cordis: The dilator works just like a trauma catheter: they screw together and get inserted together over the guidewire. The longer wire (distal) inserts into the negative port ( Dear manufacturer, thanks for not labeling these with a “+” and “-”. The proximal (shorter) wire inserts into the positive port ( Proximal = Positive). The non-sterile person tightens the thumb screws. The non-sterile person holds the hub while the sterile person inserts the wires. The wires are attached by thumb-screws on the non-sterile hub. The pacer has two short sterile wires and the generator has one long non-sterile wire. ![]() ![]() This is a tricky step, and must be done before the pacer gets inserted into the patient. Prophylaxis for expected clinical course: there is some literature that suggests placement of a TV pacer in a patient with a new onset LBBB or RBBB with left axis deviation due to acute MI, as up to 43% of them will develop high degree AV block. Transcutaneous pacing did not achieve mechanical capture: The Lifepak is firing but on your bedside echo you don’t see the LV squeezing at the same rate.ģ. It’s never ideal to have to place a patient on pressors to compensate for sedation.Ģ. Transcutaneous pacing worked so well, the hemodynamically unstable patient is now mentating and screaming from the electrical shocks. Drug Overdose - with the goal of maintaining adequate hemodynamics while your medical therapy/dialysis has an opportunity to work. AV Block - may be due to ischemia (15-19% of all Acute MI) ģ. Sinus Bradycardia - seen in 17% of acute MI patients (especially inferior or anterior wall MI) Ģ.
