Abstract:
A pattern of multiple organ dysfunction syndrome (MODS) and risk factors following blunt trauma was identified, based on analyses of clinical data from 3611 patients who were admitted directly to a level I trauma centre and had hospital stays > or = 3 days. Five system dysfunctions were simultaneously associated (P < 0.05) with death (adjusted odds ratio): adult respiratory distress syndrome (ARDS) (4.9), renal failure (6.7), hyperglycaemia (3.6), recurrent acidosis (4.8) and hypoalbuminaemia (1.8). Mortality increased with the number of system dysfunctions. For the 336 patients with MODS (> or = 2 dysfunctions), mortality was 32.4 per cent compared with 1.3 per cent in the non-MODS group (P = 0.0001). Of the 254 with MODS occurring within 72 hours, mortality was 27 per cent compared with 49 per cent in those manifesting MODS later (P < 0.001). The 175 (52.1 per cent) with organ failure (renal failure and/or ARDS) also had metabolic dysfunction. Seven admission risk factors were independently associated (P < 0.003) with MODS [adjusted odds ratio]: pre-existing condition (3.4), age > 50 (3.1), Injury Severity Score > or = 25 (6.4), hypotension (2.8), acidaemia (2.2), 24 h blood loss > 1 l (3.7), and major base deficit (1.6). Only 13 per cent with MODS had an infection in the 5 days before or at initiation of MODS. Haemodynamic instability, acidosis, blood loss, pre-existing condition, age and serious injury were risk factors independently related to life-threatening MODS, but infection was an uncommon precursor except in late MODS.(ABSTRACT TRUNCATED AT 250 WORDS)
Insights
Multiple organ dysfunction syndrome (MODS) in blunt trauma patients is linked to higher mortality. Key risk factors include injury severity, hypotension, and acidosis, not typically infection.
Area of Science:
- Trauma Surgery
- Critical Care Medicine
- Clinical Epidemiology
Background:
- Multiple organ dysfunction syndrome (MODS) is a significant cause of mortality in trauma patients.
- Identifying risk factors and patterns of MODS is crucial for improving patient outcomes.
Purpose of the Study:
- To identify patterns of MODS and associated risk factors in patients with blunt trauma.
- To analyze the relationship between MODS, its timing, and mortality.
Main Methods:
- Analysis of clinical data from 3611 blunt trauma patients admitted to a Level I trauma center.
- Statistical analysis to identify independent risk factors and associations with mortality.
Main Results:
- Five dysfunctions (ARDS, renal failure, hyperglycemia, acidosis, hypoalbuminemia) were associated with death.
- Mortality increased with the number of system dysfunctions; 32.4% for MODS vs. 1.3% for non-MODS.
- Admission risk factors for MODS included pre-existing conditions, age > 50, high Injury Severity Score, hypotension, acidaemia, blood loss, and base deficit.
Conclusions:
- MODS significantly increases mortality risk in blunt trauma patients.
- Early identification of risk factors like hemodynamic instability, acidosis, and severe injury is vital.
- Infection is an uncommon precursor to MODS, except in cases of late-onset MODS.
