The use of point-of-care ultrasound to guide clinical management in intra-abdominal hypertension.

ABSTRACT:

Introduction

The Abdominal Compartment Society (WSACS) developed a medical management algorithm with a stepwise approach to keep intra-abdominal pressure (IAP) ≤ 15 mm Hg. The role of point-of-care ultrasound (POCUS) as a bedside modality in the critical care patients is not well studied in relation to the intra-abdominal hypertension (IAH) management algorithm.

Aim

To test the role of point-of-care ultrasound (POCUS) in the medical management of patients with intra-abdominal hypertension (IAH).

Method

We conducted a prospective observational study. Those who met the inclusion criteria were assigned to undergo POCUS and small bowel ultrasound as adjuvant tools in their IAH management.

Results

A total of 22 patients met the inclusion criteria and were included in the study. The mean age of the study participants was 65 ± 22.6 years, 61% were men, and the most frequent admission diagnoses were hepatic encephalopathy and massive ascites (five cases). Ultrasound and abdominal X-rays were comparable in confirming correct NGT position, but the ultrasound was superior in determining the gastric content (fluid vs. solid) and diagnoses of gastric paresis in two cases. Small bowel obstruction was present in four patients and confirmed with abdominal CT; two of the patients underwent surgical intervention for mesenteric vessel occlusion and transmesenteric internal hernia. Enema treatment was found to empty the bowel incompletely 72%, 56%, and 42% of the time on days 1, 2, and 3, respectively. Four patients with cirrhosis admitted with upper gastrointestinal bleeding and hepatic encephalopathy (out of a total of 8) were found to have large amounts of ascites, and US-guided paracentesis was performed.

Conclusion

POCUS can be used in the nonoperative management of IAH. It is an important tool in the diagnosis and treatment of patients with IAH.

Project description:BackgroundIntra-abdominal hypertension (IAH) is a common complication in critically ill patients. This study aimed to identify independent risk factors for IAH and generate a nomogram to distinguish IAH from non-IAH in these patients.MethodsWe retrospectively analyzed 89 critically ill patients and divided them into an IAH group [intra-abdominal pressure (IAP) ≥12 mmHg] and a non-IAH group (IAP <12 mmHg) based on the IAP measured from their bladders. Ultrasound and clinical data were also measured. Univariate and multivariate logistic regression analyses were performed to identify independent risk factors for IAH. The correlation between IAP and independent risk factors was also assessed.ResultsOf these 89 patients, 45 (51%) were diagnosed with IAH. Univariate analysis showed there were significant differences in the right renal resistance index (RRRI) of the interlobar artery, the right diaphragm thickening rate (RDTR), and lactic acid (Lac) between IAH and non-IAH groups (P<0.001). Multivariate logistic regression analysis revealed that increasing RRRI, RDTR, and Lactic acid (Lac) were independent risk factors for IAH (P=0.001, P=0.001, and P=0.039, respectively). IAP was significantly correlated with RRRI, RDTR, and Lac (r=0.741, r=-0.774, and r=0.396, respectively; P<0.001). The prediction model based on regression analysis results was expressed as follows: predictive score = -17.274 + 31.125 × RRRI - 29.074 × RDTR + 0.621 × Lac. Meanwhile, the IAH nomogram prediction model was established with an area under the receiver operating characteristic (ROC) curve of 0.956 (95% confidence interval: 0.909-1.000). The nomogram showed good calibration for IAH with the Hosmer-Lemeshow test (P=0.864) and was found to be applicable within a wide threshold probability range, especially that higher than 0.40.ConclusionsThe noninvasive nomogram based on ultrasound and clinical data has good diagnostic efficiency and can predict the risk of IAH. This nomogram may provide valuable guidance for clinical interventions to reduce IAH morbidity and mortality in critically ill patients.

Project description:BackgroundLiver cirrhosis and ascites are risk factors for intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS); however, data is scarce. We aimed to determine the prevalence of IAH/ACS in a population of critically ill cirrhotic patients with acute medical illness in intensive care and to assess for risk factors and clinical outcomes.MethodsThis was a multicentric retrospective cohort study including two general ICUs and pooled data from a multicentric study between January 2009 and October 2019.ResultsA total of 9,345 patients were screened, and 95 were included in the analysis. Mean age was 56.7±1.3 years, and 79% were male. Liver cirrhosis etiology included alcohol in 45.3% and alcohol plus hepatitis C virus in 9.5%. Precipitating events included infection in 26% and bleeding in 21% of cases. Mean severity score MELD and SAPS II were 26.2±9.9 and 48.5±15.3, respectively, at ICU admission. The prevalence of IAH and ACS was respectively 82.1% and 23.2% with a mean value of maximum IAP of 16.0±5.7 mmHg and IAH grades: absent 17.9%, I 26.3%, II 33.7%, III 17.9%, and IV 4.2%. Independent risk factors for IAH were alcoholic cirrhosis (p = 0.01), West-Haven score (p = 0.01), and PaO2/FiO2 ratio (p = 0.02); as well as infection (p = 0.048) for ACS. Overall, 28-day mortality was 52.6% associated with higher IAP and ACS, and independent risk factors were MELD (p = 0.001), white blood cell count (p = 0.03), PaO2/FiO2 ratio (p = 0.03), and lactate concentration (p = 0.04) at ICU admission.ConclusionsThis study demonstrates a very high prevalence of IAH/ACS in the critically ill cirrhotic patient in intensive care. Increased IAP and ACS were associated with severity of disease and adverse outcomes and independent risk factors for IAH were alcoholic cirrhosis, hepatic encephalopathy and PO2/FiO2 ratio, as well as infection for ACS. Early diagnosis, prevention, and treatment of IAH/ACS might improve outcome in critically ill cirrhotic patients.
