Physical function after pulmonary rehabilitation as a predictor of weaning success and short‐term and mid‐term survival in patients requiring prolonged mechanical ventilation

syndrome (ARDS) and alimentary tract haemorrhage following mass ingestion of methylisothiazolinone. Results: A 42-year man emergently presented with burning throat and abdominal pain after accidental ingestion of about 10 mL MIT with concentration of 14%. Gastric lavage was immediately operated. The patient felt severe progressive respiratory distress and had to undergo an emergency tracheotomy and receive ventilator care. The physical examination revealed conjunctival haemorrhage (Figure 1) and abdominal distention. The CT revealed pleural effusion and oropharynx constriction (Figure 2). APACHE2 score equals 7 and SOFA score 2. The patient received a diagnosis of acute respiratory distress syndrome (ARDS) and alimentary tract haemorrhage based on the data (symptoms, signs, and laboratory tests), which showed the rapidly deteriorating condition following mass ingestion of MIT. Symptomatic treatments were continued and the patient prognosed well. Conclusion: Though the patient in our case recovered from ARDS and alimentary tract haemorrhage, long-term follow-up is necessary because experimental evidences showed that peripheral airway dysfunction following only exposure to a mixture of CMIT/MIT is irreversible, suggesting a possibility of pulmonary damage that was expected to be considerably severe. This notable case also helps clinicians, patients, families, and other workers to better understand the importance of norm in regulating MIT use in practice.
