Characteristics of traumatic out-of-hospital cardiac arrest patients presenting to major centers in Karachi, Pakistan-a longitudinal cohort study.

There was no survival after a traumatic OHCA in Karachi, Pakistan. Even though ambulances reached the scene in a very short time, pre-hospital interventions were largely absent. There is a strong need to strengthen our pre-hospital care system but most importantly train the general public to deal with emergencies and be able to provide timely bystander CPR.
