You are building a wall–this analogy from Dr.Sensitivity is backwards (when you go higher it is less sensitive).Need to pause or be less than patient's intrinsic rate and turn down to 0.1 mA.Really want to be < 1 mA threshold How to Deal with It Not Going Where You Want it To Point of Controversy: Do you need to deflate the balloon when pulling back to try again? Turn Down DanceĢ0 > 15 > 10 > 5 > 3 > 2 > 1 > Deflate > Have them Cough (Pre-Covid) = Win (2.5-3x threshold) If you hit 50 cm (unless they are really tall) consider pulling back and starting again Get an Xray (RV placement will show the wire cross the midline).Secure by first clamping down on the wire then attaching down distal and clamping proximal portions of sheath and suture the introducer to the patient.Advance somewhat rapidly until your mech capture method shows capture (ECG is a hint, but don't rely on it).Call for balloon up (Note be GENTLE with balloon inflation/and only passive deflation.Attach to wire extender to the box, the pacemaker pins and tighten!!!! (Write Negative=Distal on your Pacemaker Drawer).Test the balloon (Special Syringe only allows 1.5 ml of air).Put the damn sterile sheath on the wire.Position the Patient so you can see the monitor.Introducer Sheath is in (If the patient NEEDS a pacemaker–an experienced person should put in the introducer).You really want a kit–I recommend: Argon 008566A.1, 2 However, the life-long pacing requirement in linearly growing paediatric patients presents ongoing unique challenges to lead selection. Procedure for Blind Placement You need a mechanical capture monitor With the advances in pacemaker generator and lead designs over the past three decades, there has been a gradual shift towards placement of transvenous pacing systems in young children with encouraging short and medium to long-term outcomes. The machine has 15 seconds of stored power to change the battery. Since mechanical capture can fail frequently, it is wise to prepare for the next step, transvenous pacing, immediately. You have 24-hrs from warning to failure (but don't wait). Remember PSI-pace, sense, action for the 3-letter convention If you turn down Atrial to zero when it starts up, it will turn to VVI Starts up in DOO at 25 mA or Push Emergency RIJ > L Subclav > LIJ > R Subclav > Femoral.Sometimes: Prophylactic for new LBBB or RBBB with left axis deviation due to acute MI (Ideally in the cath lab) ĭiscussion of Stable High Degree Heart Blocks Site.Overdrive Pacing for unstable tachydysrhythmias, especially Torsades de Pointes (polymorphic VT due to long QT).Unstable Bradycardia (2nd Degree II or 3rd Degree Heart Block). In this EMCrit Episode, I go through the procedure in intricate detail–by the end of it, you will be exposed to all aspects of pacemaker placement. This procedure can be life-saving, but it requires a diligent regime of knowledge retention and a department with good clinical logistics. Being able to competently float a transvenous pacemaker is the mark of a resuscitationist.
