Dr. CARRICO. I believe we were to where the endotracheal tube had been inserted. After this, the President--his respirations were assisted by the Bennett machine. We again listened to his chest to attempt to evaluate the respirations. Breath sounds were diminished, especially on the right, despite the fact that the endotracheal tube was in place and the cuff inflated, there continued to be some leakage around the tracheal wound. For this reason Dr. Perry elected to perform a tracheotomy, and instructed some of the other physicians in the room to insert chest tubes, thoracotomy tubes. At the beginning of the resuscitation attempt intravenous infusions had been started using polyethylene catheters by venesection, lactated renger solution, and uncross-matched type O Rh negative bloods were administered and 300 mg. of hydrocortisone were administered. Shortly after the completion of the tracheotomy, Dr. Bashour arrived and had connected the cardiac monitor. Although I never saw evidence of cardiac activity, electrical cardiac activity, Dr. Clark stated that there was a perceptible electrical beat which shortly thereafter disappeared, and closed cardiac massage was instituted. The cardiac massage was successful in maintaining carotid and radial pulses, but the patient's state rapidly deteriorated and at approximately 1 o'clock he was pronounced dead. Mr. SPECTER. What, in your opinion, was the cause of death? Dr. CARRICO. A head injury. Mr. SPECTER. Have you now described all the treatment which was given to the President as best you recollect it? Dr. CARRICO. As I recall; yes, sir; that's all--I'm sorry. Mr. SPECTER. Did you have any occasion or opportunity to examine the President's clothing? Dr. CARRICO. We did not do that. Mr. SPECTER. And was no examination of clothing made, Dr. Carrico? Dr. CARRICO. Again, this was a matter of time. The clothes were removed by the nurses, as is the usual practice, and the full attention was devoted to trying to resuscitate the President. Mr. SPECTER. On the examination of the President's back which you described that you performed, did you note any bleeding from the back? Dr. CARRICO. There was considerable blood on the cart and on his back. I could not tell if this came from his back or had fallen down from the head injury. There was also some cerebral tissue there. Mr. SPECTER. What did your examination by feeling disclose with respect to whether he had any back wound? Dr. CARRICO. I did not feel any. Now, this certainly wouldn't detect a small bullet entrance. All this examination is designed to do is to establish the fact that there is no gross injury to the chest posteriorly. Mr. SPECTER. Is that a routine type of examination, to ascertain whether there is a gross injury to the chest posteriorly? Dr. CARRICO. Yes, sir. Mr. SPECTER. What did you observe as to the President's clothing with respect to the presence of a back brace, if any?
