I have a patient with a diagnosis of hemothorax secondary accidents for motor vehicles. he has a tube draining blood into the chest, bright red, and some bruises on his shoulders, face and head, and TPN. the patient in shock, and I carry out the vital functions, all neuroscience 2 hours.
I understand that the chest trauma caused by the accumulation of blood in the thoracic cavity, resulting in the need for CTT.
