Residence: Mumbai
Medical Case: Intermittent Organophosphorus (OP) Toxicity with Intermediate Syndrome
Age: 13 years
Doctor: Dr. Soonu Udani, Medical Director & Head of Critical Care & Emergency Services
Concerns at time of Registration at SRCC:
- Patient arrived intubated and sedated
- Absence of brainstem reflexes (suggesting possible irreversible brain injury)
- Pinpoint pupils
- Severe bronchospasm
- History of recurrent episodes of neuromuscular weakness, excessive sweating, profuse secretions, and altered consciousness
- Relapsing symptoms after initial improvement at previous hospital
- Unknown cause despite 4 days of investigation at previous facility
- Suspected toxicological or neurological crisis with unclear etiology
History:
Previously healthy 13-year-old girl presented with recurrent episodes of neuromuscular weakness, altered sensorium, and respiratory distress of unclear cause, later diagnosed as organophosphorus poisoning.
Milestones:
- Initial Hospital Admission: The child was admitted to another hospital with sudden onset of dizziness, excessive sweating, limb weakness, and altered consciousness.
- Intubation for Respiratory Failure: Due to worsening symptoms and risk of respiratory arrest, she was intubated and placed on ventilatory support.
- Symptom Relapse After Initial Recovery: Despite temporary improvement, her symptoms recurred within 24 hours, requiring re-intubation and further critical care.
- Transfer to SRCC Children’s Hospital: After four days of inconclusive investigation, she was referred to SRCC Children’s Hospital, managed by Narayana Health, for advanced evaluation.
- Critical Presentation on Arrival: On arrival, the child was intubated, sedated, lacked brainstem reflexes, had pinpoint pupils, and showed signs of severe bronchospasm.
- Fluctuating Clinical Course Observed: After sedation was withdrawn, she briefly improved before rapidly deteriorating again—an unusual pattern that prompted further investigation.
- Suspicion of Organophosphorus Poisoning: The clinical team considered a rare diagnosis of intermittent organophosphorus toxicity based on cyclical symptoms and lack of improvement.
- Confirmatory Diagnostic Tests: Nerve conduction study and red blood cell cholinesterase levels were conducted, confirming OP poisoning with low enzyme levels.
- Initiation of Antidotal Therapy: The patient was started on atropine and pralidoxime (PAM), the standard treatment for OP poisoning, leading to rapid improvement over 72 hours.
- Full Neurological Recovery and Discharge: The patient was successfully extubated, regained full neurological function (except transient ulnar nerve deficit), and was discharged in stable condition
Experience at SRCC:
For the family of the 13-year-old girl, the experience was nothing short of a nightmare turned into a miracle. The ordeal began with what seemed like a sudden and mysterious illness. Their previously healthy daughter collapsed with symptoms of dizziness, weakness, excessive sweating, and confusion. Within hours, she was on a ventilator, fighting for her life. Despite being in a hospital, her condition kept deteriorating, and the lack of a clear diagnosis left the family feeling helpless and terrified. After four days of uncertainty and no clear answers, the decision to shift her to SRCC Children’s Hospital, managed by Narayana Health, Mumbai was made in the hope of better clarity. On arrival, she was unconscious, sedated, and barely responsive—raising fears of permanent brain damage. But at SRCC, the family saw a change. The doctors took immediate action, questioned every detail, and stayed vigilant despite an unclear history. The team never gave up. Even when her symptoms briefly improved and then worsened again, the doctors dug deeper instead of accepting defeat. When the real cause—organophosphorus poisoning—was finally identified, the family was shocked but relieved that there was a treatment path. The administration of atropine and pralidoxime (PAM) began immediately, and within a few days, their daughter was slowly waking up, breathing on her own, and responding.
Finally, after days of fear and uncertainty, they saw her smile again.
“We thought we were losing her. But the doctors here gave her a second chance at life. We will never forget the care, dedication, and expertise shown by every single person in this hospital.” – said the patient’s mother, with tears of gratitude.
“We urge all parents to be vigilant about what children consume, especially in school settings. This could happen to anyone—and early action is everything.” – added the patient’s father.
Today, their daughter is back home, fully recovered, attending school again, and looking forward to a normal life—with a stronger family and a powerful story of survival.
Voices of Leadership:
Dr. Soonu Udani
Medical Director & Head of Critical Care & Emergency Services

‘’Organophosphorus poisoning, often caused by exposure to certain pesticides or contaminated substances, can present with vague and fluctuating neurological and respiratory symptoms that mimic other diseases, making early diagnosis a challenge—especially in children. In this case, the recurring nature of symptoms and absence of clear history delayed identification. Fortunately, with timely intervention and critical care support, recovery can be complete.
‘’We urge parents and schools to be vigilant about what children consume, especially substances not clearly labeled or brought from unknown sources. Early recognition and reporting of symptoms can save lives.’’
Dr. Zubin Pereira
Facility Director

“This case highlights the importance of comprehensive, multidisciplinary evaluation in paediatric critical care. Our ability to identify and manage such a rare presentation of OP toxicity reflects the strength of our clinical expertise and advanced diagnostics.”
