Bradycardia
PED-04
Diagnosis
Age · HR
- < 30 days · < 100
- ≥ 30 days < 1 yr · < 80
- ≥ 1 yr · < 60
UNSTABLE: Hypotensive, pulseless, or poor perfusion
Start chest compressions, go to CARDIAC ARREST
- Epinephrine 10 MICROgrams/kg IV
- Confirm NSR. If heart block or slow junction/ventricular, call Intraoperative Electrophysiology
- Call for transcutaneous pacer (go to INSTRUCTIONS FOR PACING and start when available)
- Consider ECMO
STABLE: NOT hypotensive, pulseless, or poor perfusion
Treat underlying etiology:
- If hypoxia (common): Increase O2 to 100%, ensure ventilation, and go to HYPOXIA
- If vagal: Atropine 0.01-0.02 mg/kg IV
- If Surgical Stimulation: Stop stimulation and if laparoscopy, desufflate
- If Ca-Channel Blocker Overdose: Calcium chloride 10-20 mg/kg IV or Calcium gluconate 50 mg/kg IV. If ineffective, Glucagon as dosed below
- If Beta-Blocker Overdose: Glucagon 50 MICROgrams/kg IV, then 0.07 mg/kg/hour IV infusion (MAX 5 mg/hr) and check blood sugar
Crisis Management (If Severe)
Notify surgeon, call for help and code cart
Call for Transesophageal Echocardiography
Start chest compressions
Give epinephrine 10 MICROgrams/kg IV/IO
If cardiac arrest, go to CARDIAC ARREST
Consider ECMO
Drugs
| Atropine | 0.01-0.02 mg/kg IV |
|---|---|
| Calcium chloride | 10-20 mg/kg IV |
| Calcium gluconate | 50 mg/kg IV |
| Glucagon | 50 MICROgrams/kg IV |
| Glucagon | Then infusion 0.07 mg/kg/hour IV, MAX 5 mg/hr |
Instructions for Pacing
1. Place pacing ECG electrodes AND pacer pads on chest per package instructions
2. Turn monitor/defibrillator ON, set to PACER mode
3. Set PACER RATE (ppm) to desired rate/min. (Can be adjusted up or down based on clinical response once pacing is established)
4. Increase the milliamperes (mA) of PACER OUTPUT until electrical capture (pacer spikes aligned with QRS complex; threshold normally 65‐100mA)
5. Set final mA to 10mA above this level
6. Confirm pulse is present
7. Must change pacing pads hourly to avoid burns
8. Return to Tx
