Pre-procedure |
Checked |
I. Check for contraindication for adenosine stress test |
|
1. Known hypersensitivity to adenosine |
|
2. Known or suspected bronchoconstrictive or bronchospastic disease |
|
3. Heart block more than first degree |
|
4. Significant sinus bradycardia (resting heart rate <45 bpm) |
|
5. Systemic arterial hypotension (<90 mmHg) or severe arterial hypertension |
|
6. Recent myocardial infarction within 3 days |
|
II. Obtain informed consent |
|
III. Perform pre-procedure 12 leads ECG and review by doctor in charge |
|
IV. Place two angiocatheters intravenously to each arm: |
|
1. One IV 20G in antecubital fossa for contrast |
|
2. One IV 20–22G for adenosine infusion |
|
V. Set up infusion pump for adenosine: |
|
Drugs dosage: adenosine 0.14mg/kg/min |
|
Patient’s body weight (BW) = _________ kg; Adenosine concentration _________mg/ml |
|
0.140 (mg/kg/min) × BW (kg)/Adenosine concentration (mg/ml) = |
|
Infusion rate _________ (ml/min) =_________ (ml/h) |
|
Total dose of adenosine to be administrated: |
|
0.14 (mg/kg/min) × BW (kg) × Infusion time (min) = _________ mg |
|
During-procedure |
|
1. Oxygen 2 l/min per nasal cannula |
|
2. Set BP cuff to manual mode. Place BP cuff opposite arm as med administration. |
|
3. Record baseline vital signs- prior to medication administration |
|
4. Aminophylline 125 mg in 50 ml normal saline IVB over 5–6 min prn chest pain and shortness of breath |
|
5. Start adenosine infusion at am/pm (time). Continue vital sign monitoring as shown |
|
Post procedure |
|
1. Perform post stress ECG and review |
|
2. Record final vital signs prior to discharge. Report any patient complaints to doctor in charge |
