There have been no reports regarding imaging-documented bronchospasm in patients with amniotic fluid embolism (AFE). In a woman with scheduled cesarean section for placenta previa, transient bronchospasm and pulmonary hypertension were documented explaining a sudden drop in SpO2. Mild AFE was the most likely diagnosis in this patient.

Effect of Thyroxine was studied in histamine induced bronchospasm in guinea pigs. Chronic treatment with the drug significantly protected against experimental bronchospasm. Thyroxine also potentiated salbutamol evoked bronchodilation in this experimental model. Up-regulation of beta-2 adrenoceptors in bronchial smooth muscle may be the probable mechanism of action of thyroxine.

exercise induced asthma (eia) is a transient increase in airway resistance after intensive exercise and can be measured as a decline in forced expiratory volume in one second (fev1). the condition is due to increased training load and inhalation of cold and dry air. several studies have shown that eucapnic voluntary hyperpnea challenge test (evh test) is a very sensitive and specific diagnostic...

Superselective ophthalmic artery injection of the chemotherapeutic agent is a new treatment option for advanced retinoblastoma.[1] We present case severe bronchospasm with loss tidal volume and oxygen desaturation in an infant during catheterization under general anesthesia.

Acute severe bronchospasm is an emergency situation and sometimes these children may fail to respond to conventional treatment and deteriorate rapidly to respiratory failure requiring mechanical ventilation. We present a case of 2-year-old girl, who presented with severe bronchospasm resulting in respiratory failure not responding to conventional management including mechanical ventilation and ...

We present an interesting case of profound bronchospasm that we postulate was caused by injection of ethanol during embolization of a left transverse sinus dural fistula. There is excellent documentation in the literature of the development of transient pulmonary hypertension and decreased right-side cardiac output following embolization with this agent; however, there have been only anecdotal ...
