Insights
Post-traumatic intra-abdominal hypertension is common after trauma resuscitation, but abdominal compartment syndrome is rare. Advances in haemostatic resuscitation have improved outcomes for trauma patients.
Area of Science:
- Trauma surgery
- Critical care medicine
- Surgical outcomes
Background:
- Assessing the incidence and outcomes of post-traumatic intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS).
- Evaluating these conditions following advancements in haemostatic resuscitation strategies.
Purpose of the Study:
- To determine the incidence and outcomes of post-traumatic IAH and ACS.
- To analyze the impact of current resuscitation techniques on these conditions.
Main Methods:
- Prospective cohort study (2009-2011) of patients with post-traumatic hemorrhagic shock.
- Assessment of demographics, fluid resuscitation, damage control laparotomy (DCL), morbidity, and mortality.
- Patients categorized into groups based on DCL need and intra-abdominal pressure (IAP) levels.
Main Results:
- 117 patients enrolled; 15 required DCL, showing higher mortality (20% vs 6%).
- IAH was common (IAP 12-20 mmHg in 57.8%), but ACS incidence was low (0.9%).
- Patients with IAP > 20 mmHg exhibited worse metabolic acidosis and required more blood transfusions.
Conclusions:
- IAH is a frequent, transient issue in trauma patients with current resuscitation practices.
- The incidence of ACS is notably low, suggesting effective management strategies.
- Minimal fluid resuscitation and damage control approaches contribute to favorable outcomes.
Background:
This study aimed to determine the incidence and outcome of post-traumatic (PT) intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) after the advances in haemostatic resuscitation.
Methods:
This is a prospective cohort study from January 2009-December 2011 involving patients with PT haemorrhagic shock. Patients' demographics, fluid resuscitation (<24 h) and damage control laparotomy (DCL), morbidity and mortality were assessed. Patients were divided into group 1 (no DCL) and group 2 (DCL needed). Further, group 1 was subdivided into three subgroups (IA pressure (IAP) <12, 12-20 and >20 mmHg).
Results:
One hundred seventeen patients enrolled in the study (102 in group 1 and 15 in group 2) with a mean age of 35 ± 14, injury severity score (ISS) of 23 ± 10, base deficit of -8.7 ± 2.7 mmol/L, serum lactate of 4.6 ± 2.5 mg/dL and haemoglobin level of 8.8 ± 2. Patients received 7 ± 5 red blood cell units, 6 ± 4.7 fresh frozen plasma units and 8.3 ± 3 L of crystalloid per 24 h. There were significant difference between the two groups regarding crystalloid volume, blood transfusion, base deficit and intensive care unit length of stay. However, mortality was higher in group 2 (20% versus 6%). IAP ≥ 20 mmHg was reported in 16.7% patients, while 25.5% had IAP < 12 and 57.8% had IAP of 12-20 mmHg. Patients with IAP > 20 had worse metabolic acidosis and received more blood compared with other groups. One patient died because of ACS (0.9%). Overall multiorgan failure and mortality were 5 and 7.7%, respectively.
Conclusion:
With current practice of minimal fluid resuscitation and liberal use of damage control strategies among trauma patients, the IAH was common transient phenomena but the incidence of ACS is remarkably low.
