Patient: Female, 37 Final Diagnosis: Cardiac arrest due to Benzonatate overdose Symptoms: Cardiac arrest • respiratory deterioration • seizure Medication: Benzonatate Clinical Procedure: Intubation • hypothermia protocol Specialty: Critical Care Medicine Objective: Unknown ethiology Background: Benzonatate is one of the most widely prescribed nonnarcotic antitussives to relieve cough symptoms. As a structurally similar agent to other local anesthetics, including tetracaine and procaine, the risk to the public is not fully appreciated. Case Report: A 37-year-old female presented to the Emergency Department (ED) status post cardiac arrest. Advanced cardiac life support (ACLS) protocol was performed, and return of spontaneous circulation (ROSC) was achieved. Total downtime was 30 minutes. The patient was intubated, sedated, and hypothermia protocol was initiated. The patient developed bradyarrhythmia and mild coagulopathy suspicious for disseminated intravascular coagulation (DIC), thus hypothermia protocol was terminated later. A review of laboratory data showed acidosis with pH of 6.87, mixed acidosis secondary to high anion gap metabolic and respiratory acidosis with elevated liver enzymes. It was reported that approximately 2 hours prior to her presentation; the patient had ingested less than 30 pills of benzonatate 200 mg capsules with alcohol. Conclusions: Ingestion of benzonatate, a widely prescribed antitussive, may pose a risk to patients due to the potential for rapid development of life-threatening adverse events and limited treatment options in the overdose setting, not only in children but also in adults. Rational prescribing and patient education are needed.

Cavity formation after pulmonary embolism can be a result of infarction; however, the data available on the incidence rate were obtained from the cases of patients treated with anticoagulation without recanalization. It is yet unknown if interventions like catheter-directed alteplase or thrombectomy reduce the risk of cavity formation. We present an interesting case of a patient who developed pulmonary cavity and possible secondary infection after successful vascular recanalization with catheter-directed alteplase and thrombectomy.

Critically ill patients cannot complain about eye problems. Eyecare is often overlooked in the intensive care units (ICUs) because treatment is mainly focused on failures of organ which results in eye complications which are preventable. Therefore, we report a case of a patient admitted to the ICU who developed unusual bilateral hemorrhagic chemosis. Although, chemosis has been encountered often in the ICU, hemorrhagic chemosis without prior direct trauma is unusual.
