Factors Affecting Outcome after Chest Injury

From 1978 to 1983 a total of 328 patients was admitted to Royal Newcastle Hospital Intensive Care Unit with chest injuries; 255 had other injuries as well. Of the 328, 171 developed acute respiratory failure, 174 received mechanical ventilation (159 for acute respiratory failure) and 46 died. The commonest causes of death were head injury (19), sepsis (10) and uncontrollable haemorrhage (10). Associated head (131) and/or abdominal (89) injuries tripled mortality. Those without respiratory, cardiac, renal or hepatic failure (155) had a mortality rate of 5.8% while the remainder had mortality rates of 21.6%, 12.5%, 37.5% and 100%, for respiratory (171), cardiac (8), renal (8) and hepatic (5) failures, respectively. Shock was present on admission in 55, of whom 19 died. Sepsis developed in 59 and 14 with this complication died. Sepsis remains a potentially avoidable late cause of death and attention needs to be directed towards limiting invasive techniques of management to those which are necessary, and towards early diagnosis of abdominal injuries with early exploratory surgery. The best chance of survival in the initial phase of injury may lie in the establishment of an integrated regional trauma centre system together with improved pre-hospital and retrieval systems.
