To assess factors associated with survival of out-of-hospital cardiac arrest (OHCA) in patients who underwent cardiopulmonary resuscitation (CPR) during ambulance transport. ⋯ Ambulance CPR by a physician on board is applied in few OHCA cases. Young patient age, cardiac arrest outside the home, the presence of a witness, lack of a shockable rhythm on responder arrival, lack of basic life support prior to responder arrival, noncardiac cause, and orotracheal intubation are associated with the use of ambulance CPR, a strategy that can be considered futile.

Spontaneous hemothorax is an uncommon event that can occur in patients with a history of neurofibromatosis type 1 because of intrathoracic vascular malformations that predispose to aneurysms or bleeding from thoracic tumors. Only 53 cases of this rare association have been reported in the literature since 1975. We described 2 cases: one patient was a 73-year-old man with a right hemothorax secondary to an intercostal neurofibroma; the other was a 35-year-old woman with a left hemothorax secondary to a neurofibroma that compromised the internal mammary artery. ⋯ There was a certain tendency toward left-sided (56.4%) hemothorax, and the intercostal space was the most common site of bleeding. Treatment was most often surgical (58.2%) in reported cases, although selective artery embolization is also a valid choice. Exitus occurred during 30.9% of the reported episodes, and survival was higher in patients who were treated with surgery or arterial embolization than in those in whom only a thoracic drain was placed or who received no invasive treatment (P=.02).
