Abstract
To analyse changes in background factors, injury pattern, and prognosis regarding blunt abdominal trauma in Sweden, the 30-year postwar (1946–75) development was investigated in a rural district. 396 patients were treated, showing a great increase during the last 5 years. The highest frequency was seen in patients aged 11–20 years. Abdominal trauma occurred most commonly during July and August. The growing aetiological importance of road accidents is shown. Equestrian accidents were common early in the period and again towards the end. The incidence of cerebrally confused patients increased. The organs most commonly traumatized were kidney, liver, and spleen. The frequency of multiple intra-abdominal injuries and also associated extra-abdominal injuries increased with time. There was a tendency towards shorter hospital stays. Mortality rates did not change during the period, even though injuries have become increasingly severe (judged by the Injury Severity Score). It is concluded that the improved care of patients compensated precisely for the increased severity of injuries, as reflected in mortality.
