Anaphylaxis is a medical emergency with the incidence between 1.6% and 5.1%. A wide array of drugs are implicated to cause anaphylaxis, but commonly implicated drugs include antimicrobials (β-lactams), nonsteroidal anti-inflammatory drugs (diclofenac sodium, ibuprofen, and aspirin), neuromuscular blockers (atracurium), and radiocontrast agents. Anaphylaxis with ranitidine is rarely seen with an incidence of 0.2%–0.7%.
We report a case of a 70-year-old female patient who was brought to the emergency department in a fully conscious state with a history of severe epigastric discomfort and two episodes of vomiting. She had no known comorbidities with a negative history of drug intake and allergy to any drugs. She was given injection intravenous (i.v.) Immediately, after the injection, the patient developed itching all over the body and complained of difficulty in breathing. Pulse rate increased from 76 beats/min (b.p. m) to 120 b.p.m. and blood pressure dropped from 130/80 to 60/30 mm Hg with an increase in respiratory rate from 15 to 40/min and pulse oximetry revealed oxygen desaturation from 96% on room air to 82% with 5 l of oxygen. Wheals appeared all over the chest and abdomen suggestive of urticaria. The patient developed bronchospasm, bradycardia, and asystole. Cardiopulmonary resuscitation (CPR) commenced without delay as per the American Heart Association guidelines for advanced cardiac life support (2015). Management of anaphylaxis followed as per guidelines laid down by the Australasian society of clinical immunology and allergy (2017). i.v. bolus of 20 mL/kg of the normal saline and intramuscular injection of adrenaline 0.5 ml of (1:1000) was administered on the outer aspect of the right thigh followed by i.v. hydrocortisone 100 mg and i.v. diphenhydramine 25 mg. There was the return of spontaneous circulation within 5 min of high-quality CPR and the i.v. infusion of adrenaline started at the rate of 0.1 μg/kg/min. The patient was shifted to the Intensive Care Unit where she was treated with ventilatory support. Adrenaline infusion was gradually tapered over next 4 h. Once her vitals improved overnight, she was extubated the next day. Her routine investigations were within normal limits. A blood sample taken at the time of adverse drug reaction revealed a raised immunoglobulin E levels (1658 IU/mL) (normal level 100–300 IU/mL).
Anaphylaxis is an unanticipated, unpredictable, severe, immediate type of allergic reaction. It is meditated by the mast and basophil cells which release large amount of mediators of inflammation and is associated with severe cardiorespiratory compromise. About 1% of total hospitalized and 0.1% of emergency department patients who had anaphylaxis had a fatal outcome. Anaphylaxis is uncommon in clinical practice. Therefore, there are always gaps in the knowledge about the treatment guidelines. A study by Kmietowicz found that only 33% of 1st year residents knew the right dose and route of adrenaline in anaphylaxis and the 2nd year residents who had completed the advanced cardiac life support were only marginally better than the 1st year residents. Antonicelli et al. and Aljubran  had reported anaphylaxis to the first dose of ranitidine in an adult and 2-month-old child. History for previous exposure of ranitidine, in this case, could not be elicited as the patient was illiterate and belonged to a rural background. In our case, the outcome was positive as the team head in the emergency department of our tertiary care center was an anesthesiologist being aware of the treatment protocols.
In our clinical practice, one should be vigilant enough to assess the sign and symptoms of the anaphylaxis as such incidents can occur even with the most commonly prescribed drugs and with no previous exposure to the implicated drug. Reinforcement of management protocols, simulation of drills and constantly updating the knowledge will help in limiting the morbidity and mortality and improving the outcome.
