Excerpt
In this issue of Intensive Care Medicine, Reintam et al. report the results of a study entitled “Primary and secondary intra-abdominal hypertension—different impact on ICU outcome” [
1]. The authors collected prospective data on 257 mechanically ventilated critically ill patients with more than two risk factors for IAH (about one-third of the entire ICU population). The authors found that IAH (defined as a sustained increase in intraabdominal pressure (IAP) equal to or above 12 mmHg) was present on admission in 23.4% of cases, while a total of 37% developed IAH within 5 days of whom 4.7% developed ACS. Primary IAH (with an underlying cause within the abdomino-pelvic region) was seen in 63.2% of patients with IAH. Patients with secondary IAH demonstrated a different time course with a significant increase of mean IAP during the first 3 days (mean ΔIAP was 2.2 ± 4.7 mmHg), whilst in the patients with primary IAH, IAP decreased (mean ΔIAP −1.1 ± 3.7 mmHg). Patients with IAH were sicker, had more organ failure and a higher ICU (37.9 vs. 19.1%;
P = 0.001), 28-day (48.4 vs. 27.8%;
P = 0.001), and 90-day mortality (53.7 vs. 35.8%;
P = 0.004) compared to patients with a normal IAP. Patients with secondary IAH had a significantly higher ICU mortality than patients with primary IAH (
P = 0.032). The development of IAH during ICU stay was an independent risk factor for death (OR 2.52; 95% CI 1.23–5.14). Therefore, ICU physicians no longer have an excuse not to obtain a baseline IAP value in patients with two or more risk factors for IAH [
