Contrast extravasation

Assessment of patient
Assessment of access site, demarcate with pen - distal pulses - paraethesias - neuromuscular defecit Record: - type - volume - encounter note Elevate limb Cold compress Monitor for an hour in department Surgical consult for fasciotomy if severe Send home with instructions to return to ED. Sx should resolve in 2 days. |

Unresponsive patient in the scanner

Assess patient
- look - skin - pulses - lungs Vitals - HR - BP - Pulse ox O2 at 6-10 L per minute Establish IV access IF hypotensive and tachycardic: - Trendelenberg - NS bolus - if poorly responsive: epinephrine (1:10,000) slowly IV 1 ml (= 0.1 mg) - repeat as needed up to a maximum of 1 mg If still poorly responsive seek appropriate assistance (e.g., cardiopulmonary arrest response team). IF hypotensive and bradycardic: - Trendelenburg position. - atropine 0.6–1 mg IV slowly if patient does not respond quickly to steps 2–4. - repeat atropine up to a total dose of 0.04 mg/kg (2–3 mg) in adult. - ensure complete resolution of hypotension and bradycardia prior to discharge. |

Contrast reaction: Urticaria?
|
1. Discontinue injection if not completed
2. No treatment needed in most cases 3. Give H1-receptor blocker: diphenhydramine (Benadryl®) PO/IM/IV 25–50 mg. If severe or widely disseminated: give alpha-agonist (arteriolar and venous constriction): epinephrine SC (1:1,000) 0.1–0.3 ml (= 0.1–0.3 mg) (if no cardiac contraindications). |

Remove needle
Assess Patient Vitals 1. Give O2 6–10 liters/min (via mask). 2. Consider diazepam (Valium®) 5 mg IV (or more, as appropriate) or midazolam (Versed®) 0.5 to 1 mg IV. 3. If longer effect needed, obtain consultation; consider phenytoin (Dilantin®) infusion — 15–18 mg/kg at 50 mg/min. 4. Careful monitoring of vital signs required, particularly of pO2 because of risk to respiratory depression with benzodiazepine administration. 5. Consider using cardiopulmonary arrest response team for intubation if needed. |

Contrast reaction: laryngospasm laryngeal edema
|
Vitals
1. Give O2 6–10 liters/min (via mask). 2. Give alpha agonist (arteriolar and venous constriction): epinephrine SC or IM (1:1,000) 0.1–0.3 ml (= 0.1–0.3 mg) or, especially if hypotension evident, epinephrine (1:10,000) slowly IV 1–3 ml (= 0.1–0.3 mg). Repeat as needed up to a maximum of 1 mg. If not responsive to therapy or if there is obvious acute laryngeal edema, seek appropriate assistance (e.g., cardiopulmonary arrest response team). |
|
Contrast reaction: bronchospasm
|
1. Give O2 6–10 liters/min (via mask).
Monitor: - electrocardiogram - O2 saturation (pulse oximeter) - blood pressure. 2. Give beta-agonist inhalers (bronchiolar dilators, such as metaproterenol [Alupent®], terbutaline [Brethaire®], or albuterol [Proventil® or Ventolin®]) 2 to 3 puffs; repeat as necessary. If unresponsive to inhalers, use SC, IM, or IV epinephrine. 3. Give epinephrine SC or IM (1:1,000) 0.1–0.3 ml (= 0.1–0.3 mg) or, especially if hypotension evident, epi- nephrine (1:10,000) slowly IV 1–3 ml (= 0.1–0.3 mg). Repeat as needed up to a maximum of 1 mg. Call for assistance (e.g., cardiopulmonary arrest response team) for severe bronchospasm or if O2 saturation <88% persists. |
|
Contrast reaction: hypotension and tachycardia
|
1. Legs elevated 60° or more (preferred) or Trendelenburg position.
2. Monitor: - electrocardiogram - pulse oximeter - blood pressure 3. Give O2 6–10 liters/min (via mask). 4. Rapid intravenous administration of large volumes of Ringer’s lactate or normal saline. If poorly responsive: epinephrine (1:10,000) slowly IV 1 ml (= 0.1 mg) Repeat as needed up to a maximum of 1 mg If still poorly responsive seek appropriate assistance (e.g., cardiopulmonary arrest response team). |
|
Contrast reaction: bradycardia and hypotension
|
Vitals and assessment
1 Secure airway: give O2 6–10 liters/min (via mask) 2. Monitor vital signs. 3. Legs elevated 60° or more (preferred) or Trendelenburg position. 4. Secure IV access: rapid administration of Ringer’s lactate or normal saline. 5. Give atropine 0.6–1 mg IV slowly if patient does not respond quickly to steps 2–4. 6. Repeat atropine up to a total dose of 0.04 mg/kg (2–3 mg) in adult. 7. Ensure complete resolution of hypotension and bradycardia prior to discharge. |
|
Contrast reaction: severe hypertension
|

For pheochromocytoma: phentolamine 5 mg IV (may use labetalol if phentolamine is not available). |
|
Contrast reaction: seizures or convulsions
