3. There were 8 deaths, giving a mortality‐rate of 14 per cent.
4. The number of associated injuries was the most important single factor influencing the mortality‐rate.
5. Delay in diagnosis occurred in 14 patients, and this may contribute to the high mortality‐rate of blunt abdominal injury.
6. A high index of suspicion, thorough and repeated clinical assessment, and willingness to resort to laparotomy are the main principles in the diagnosis of blunt abdominal injury.
