| Hives (uticaria) | 
			
			
				- Discontinue injection if not completed
 
				- No treatment needed in most cases - reassure the patient
 
				- Consider diphenhydramine (Benadryl®) PO/IM/IV 25-50 mg
 
				- If severe/widely disseminated: Epinephrine SC (1:1,000) 0.1-0.3 ml (=0.1-0.3 mg) (if no cardiac contraindications)
 
			 
			 | 
		
		
			| Facial or Laryngeal Edema | 
			
			
				- 0.1-0.3 ml epinephrine SC or IM (1:1,000) (=0.1-0.3 mg) or, if hypotensive, 1 ml epinephrine IV (1:10,000) slowly (=0.1 mg). Repeat as needed up to 1 mg.
 
				- Give oxygen 6-10 L/min (via mask)
 
				- If not responsive to therapy or if there is obvious acute laryngeal edema, seek appropriate assistance (e.g., cardiopulmonary arrest response team).
 
			 
			 | 
		
		
			| Bronchospasm | 
			
			
				- Give oxygen 6-10 L/min (via mask)
 
				- Monitor: ECG, O2 saturation (pulse oximeter), and BP
 
				- Give beta-agonist inhalers, such as metaproterenol (Alupent®), terbutaline (Brethaire®), or albuterol (Proventil®)(Ventolin®) 2-3 puffs; repeat as needed
 
				- If unresponsive, epinephrine SC or IM (1:1,000) 0.1-0.3 ml (=0.1-0.3 mg) or, if hypotensive, epinephrine (1:10,000) slowly IV 1 ml (=0.1 mg) - Repeat up to 1 mg
 
				- Alternatively, give aminophylline 6 mg/kg IV in D5W over 10-20 minutes (loading dose), then 0.4-1 mg/kg/hr, as needed (caution: hypotension)
 
				- Call for assistance for severe bronchospasm or if O2 saturation < 88% persists
 
			 
			 | 
		
		
			| Hypotension with Tachycardia | 
			
			
				- Legs elevated 60° or more (preferred) or Trendelenburg position
 
				- Monitor: ECG, O2 saturation (pulse oximeter), and BP
 
				- Give oxygen 6-10 L/min (via mask)
 
				- Rapid large volumes of IV isotonic Ringer’s lactate or normal saline
 
				- If poorly responsive: Epinephrine (1:10,000) slowly IV 1 ml (=0.1 mg) (if no cardiac contraindications). Repeat as needed up to a maximum of 1 mg
 
				- If still poorly responsive seek appropriate assistance (e.g., arrest team).
 
			 
			 | 
		
		
			| Hypotension with Bradycardia (Vagal Reaction) | 
			
			
				- Monitor: ECG, O2 saturation (pulse oximeter), and BP
 
				- Legs elevated 60° or more (preferred) or Trendelenburg position
 
				- Secure airway and give oxygen 6-10 L/min (via mask)
 
				- Rapid large volumes of IV isotonic Ringer’s lactate or normal saline
 
				- If unresponsive, atropine 0.6-1 mg IV slowly - repeat up to 2-3 mg in adult
 
				- Ensure complete resolution of hypotension and bradycardia prior to discharge.
 
			 
			 | 
		
		
			| Severe Hypertension | 
			
			
				- Give oxygen 6-10 L/min (via mask)
 
				- Monitor: ECG, O2 saturation (pulse oximeter), and BP
 
				- Give nitroglycerine 0.4-mg tablet, sublingual (may repeat x 3)
 
				- Transfer to intensive care unit or emergency department
 
				- For pheochromocytoma—phentolamine 5 mg IV
 
			 
			 | 
		
		
			| Seizures or Convulsions | 
			
			
				- May be consequence of hypotension, primary treatment should be as indicated
 
				- Lateral decubitus position, give oxygen, 6-10 L/min by mask
 
				- Consider diazepam (Valium®) 5 mg or more or midazolam (Versed®) 0.5-1 mg IV
 
				- If longer effect needed, obtain consultation; consider phenytoin (Dilantin®) infusion – 15-18 mg/kg at 50 mg/min.
 
				- Careful monitoring of vital signs, particularly of pO2 (respiratory depression)
 
				- Consider using cardiopulmonary arrest response team for intubation
 
			 
			 | 
		
		
			| Pulmonary Edema | 
			
			
				- Elevate torso; rotating tourniquets (venous compression)
 
				- Give O2 6-10 liters/min (via mask)
 
				- Give diuretics – furosemide (Lasix®) 20-40 mg IV, slow push
 
				- Consider giving morphine (1-3 mg IV)
 
				- Transfer to intensive care unit or emergency department
 
				- Corticosteroids optional
