RESUMEN
Traditional surgical treatment of widespread purulent peritonitis has some disadvantages that emphasizes the need for new approaches to postoperative care. The authors present successful treatment of diffuse purulent peritonitis using a combination of 'open abdomen' technology and VAC therapy. This approach reduces abdominal inflammation and intra-abdominal pressure. Combination of 'open abdomen' technology and VAC therapy provides effective control of inflammation and stabilization of patients with purulent peritonitis.

BACKGROUND: Monitoring Intraabdominal Pressure (IAP) is essential in critical care, as elevated IAP can lead to severe complications, including Abdominal Compartment Syndrome (ACS). Advances in technology, such as digital capsules, have opened new avenues for measuring IAP non-invasively. This study assesses the feasibility and effectiveness of using a capsular device for IAP measurement in an animal model. METHOD: In our controlled experiment, we anesthetized pigs and simulated elevated IAP conditions by infusing CO2 into the peritoneal cavity. We compared IAP measurements obtained from three different methods: an intravesical catheter (IAPivp), a capsular device (IAPdot), and a direct peritoneal catheter (IAPdir). The data from these methods were analyzed to evaluate agreement and accuracy. RESULTS: The capsular sensor (IAPdot) provided continuous and accurate detection of IAP over 144 h, with a total of 53,065,487 measurement triplets recorded. The correlation coefficient (R²) between IAPdot and IAPdir was excellent at 0.9241, demonstrating high agreement. Similarly, IAPivp and IAPdir showed strong correlation with an R² of 0.9168. CONCLUSION: The use of capsular sensors for continuous and accurate assessment of IAP marks a significant advancement in the field of critical care monitoring. The high correlation between measurements from different locations and methods underscores the potential of capsular devices to transform clinical practices by providing reliable, non-invasive IAP monitoring.

Patients with emergent conditions are prone to develop intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS), which are closely associated with adverse outcomes. Currently, there is a lack of guiding documents for the management of IAH/ACS in the emergency departments in China. Based on a systematic review of recent researches and clinical experiences in emergency departments, the Emergency Medicine Branch if Chinese Medical Association and other professional organizations have jointly formulated the Emergency expert consensus on diagnosis and treatment of intra-abdominal hypertension and abdominal compartment syndrome in adults in China (2024) to enhance the diagnostic and therapeutic capabilities of emergency physicians regarding adult IAH/ACS. The consensus particularly emphasizes the importance of early identification, continuous monitoring, and timely treatment of IAH/ACS in the emergency settings. The consensus recommends routine intra-abdominal pressure (IAP) measurement for emergency patients with risk factors for IAH/ACS and suggests adjusting the monitoring frequency based on IAP levels. In terms of treatment, the consensus highlights a comprehensive approach that includes both non-surgical and surgical interventions, with additional recommendations for traditional Chinese medicine (TCM) treatments. The consensus also stresses the importance of fluid resuscitation, organ support, and preventive measures, proposing nutritional therapy and preventive strategies. The consensus provides more precise and practical guidance for the clinical diagnosis and treatment of emergency patients with IAH/ACS, which is conducive to improving clinical outcomes.

An increased intra-abdominal pressure can result in a manifest abdominal compartment syndrome (ACS) with significant organ damage, which is a life-threatening situation associated with a high mortality. Although the etiology is manifold and critically ill patients on the intensive care unit are particularly endangered, the disease is often not diagnosed even though the measurement of bladder pressure is available as a simple and standardized method; however, particularly the early detection of an increased intra-abdominal pressure is decisive in order to prevent the occurrence of a manifest ACS with (multi)organ failure by means of conservative measures. In cases of a conservative refractory situation, decompressive laparotomy is indicated.

BACKGROUND: Intra-abdominal pressure (IAP) is a frequently overlooked aspect in clinical assessment that can have a significant impact on organ dysfunction in patients with acute decompensated heart failure (ADHF). AIMS: We aimed to investigate dynamics of IAP in patients with ADHF and its impact on diuretic response. METHODS: We conducted a prospective observational pilot study on a group consisting of 30 patients admitted for ADHF. In every individual IAP measurement, blood and urine samples were taken upon admission, on the second and third days of hospitalization. RESULTS: The study showed a high (63.3%) prevalence of intra-abdominal hypertension (IAH) defined as IAP ≥12 mm Hg upon admission, while only roughly 13% had signs of ascites. We observed poorer diuresis on the first day of hospitalization in the IAH group (P = 0.03). IAP was negatively correlated with urine output (P = 0.01) and positively correlated with urine osmolality (P = 0.03) on the first day of hospitalization. During follow-up, there was a significant decrease in IAP in patients with IAH upon admission who received standard decongestive therapy. CONCLUSIONS: The study shows a high prevalence of IAH in patients admitted for ADHF, even in individuals who do not present symptoms of abdominal congestion. Established correlation between IAP, reduced diuresis, and increased urine osmolality, despite achieving target natriuresis, contributes novel insights into the understanding of pathomechanisms underlying diuretic resistance in ADHF.

In experimental medicine, a wide variety of sensory measurements are used. One of these is real-time precision pressure measurement. For comparative studies of the complex pathophysiology and surgical management of abdominal compartment syndrome, a multichannel pressure measurement system is essential. An important aspect is that this multichannel pressure measurement system should be able to monitor the pressure conditions in different tissue layers, and compartments, under different settings. We created a 12-channel positive-negative sensor system for simultaneous detection of pressure conditions in the abdominal cavity, the intestines, and the circulatory system. The same pressure sensor was used with different measurement ranges. In this paper, we describe the device and major experiences, advantages, and disadvantages. The sensory systems are capable of real-time, variable frequency sampling and data collection. It is also important to note that the pressure measurement system should be able to measure pressure with high sensitivity, independently of the filling medium (gas, liquid). The multichannel pressure measurement system we developed was well suited for abdominal compartment syndrome experiments and provided data for optimizing the method of negative pressure wound management. The system is also suitable for direct blood pressure measurement, making it appropriate for use in additional experimental surgical models.

Introduction: Intra-abdominal pressure (IAP) monitoring is crucial for the detection and prevention of intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS). In the 1970s, air-filled catheters (AFCs) for urodynamic studies were introduced as a solution to overcome the limitations of water-perfused catheters. Recent studies have shown that for correct IAP measurement with traditional AFC, the bladder needs to be primed with 25 mL of saline solution to allow pressure wave transmission to the transducer outside of the body, which limits continuous IAP monitoring. Methods: In this study, a novel triple balloon, air-filled TraumaGuard (TG) catheter system from Sentinel Medical Technologies (Jacksonville, FL, USA) with a unique balloon-in-balloon design was evaluated in a porcine and cadaver model of IAH via laparoscopy (IAPgold). Results: In total, 27 and 86 paired IAP measurements were performed in two pigs and one human cadaver, respectively. The mean IAPTG was 20.7 ± 10.7 mmHg compared to IAPgold of 20.3 ± 10.3 mmHg in the porcine study. In the cadaver investigation, the mean IAPTG was 15.6 ± 10.8 mmHg compared to IAPgold of 14.4 ± 10.4 mmHg. The correlation, concordance, bias, precision, limits of agreement, and percentage error were all in accordance with the WSACS (Abdominal Compartment Society) recommendations and guidelines for research. Conclusions: These findings support the use of the TG catheter for continuous IAP monitoring, providing early detection of elevated IAP, thus enabling the potential for prevention of IAH and ACS. Confirmation studies with the TraumaGuard system in critically ill patients are warranted to further validate these findings.

BACKGROUND: The reversible maneuver that mimics the fluid challenge is a widely used test for evaluating volume responsiveness. However, passive leg raising (PLR) does have certain limitations. The aim of the study is to determine whether the supine transfer test could predict fluid responsiveness in adult patients with acute circulatory failure who do not have intra-abdominal hypertension, by measuring changes in cardiac index (CI). METHODS: Single-center, prospective clinical study in a 25-bed surgery intensive care unit at the Fudan University Shanghai Cancer Center. Thirty-four patients who presented with acute circulatory failure and were scheduled for fluid therapy. Every patient underwent supine transfer test and fluid challenge with 500 mL saline for 15-30 min. There were four sequential steps in the protocol: (1) baseline-1: a semi-recumbent position with the head of the bed raised to 45°; (2) supine transfer test: patients were transferred from the 45° semi-recumbent position to the strict supine position; (3) baseline-2: return to baseline-1 position; and (4) fluid challenge: administration of 500 mL saline for 15-30 min. Hemodynamic parameters were recorded at each step with arterial pulse contour analysis (ProAQT/Pulsioflex). A fluid responder was defined as an increase in CI ≥ 15% after fluid challenge. The receiver operating characteristic curve and gray zone were defined for CI. RESULTS: Seventeen patients were fluid challenge. The r value of the linear correlations was 0.73 between the supine transfer test- and fluid challenge-induced relative CI changes. The relative changes in CI induced by supine transfer in predicting fluid responsiveness had an area under the receiver operating characteristic curve of 0.88 (95% confidence interval 0.72-0.97) and predicted a fluid responder with 76.5% (95% confidence interval 50.1-93.2) sensitivity and 88.2% (95% confidence interval 63.6-98.5) specificity, at a best threshold of 5.5%. Nineteen (55%) patients were in the gray zone (CI ranging from -3 and 8 L/min/m2). CONCLUSION: The supine transfer test can potentially assist in detecting fluid responsiveness in patients with acute circulatory failure without intra-abdominal hypertension. Nevertheless, the small threshold and the 55% gray zone were noteworthy limitation. TRIAL REGISTRATION: Predicting fluid responsiveness with supine transition test (ChiCTR2200058264).

BACKGROUND: Critically ill patients with cirrhosis and ascites are at high risk for intra-abdominal hypertension (IAH) which increases mortality. Clinical guidelines recommend maintaining intra-abdominal pressure (IAP) below 16 mmHg; nonetheless, more than three quarters of critically ill patients with cirrhosis develop IAH during their first week of ICU stay. Standard-of-care intermittent large-volume paracentesis (LVP) relieves abdominal wall tension, reduces IAP, optimizes abdominal perfusion pressure, and is associated with short-term improvement in renal and pulmonary dysfunction. However, there is no evidence of the superiority of different paracentesis strategies in the prevention and treatment of IAH in critically ill patients with cirrhosis. This trial aims to compare the outcomes of continuous passive paracentesis versus LVP in the prevention and treatment of IAH in patients with cirrhosis and ascites. METHODS: An investigator-initiated, open label, randomized controlled trial, set in a general ICU specialized in liver disease, was initiated in August 2022, with an expected duration of 36 months. Seventy patients with cirrhosis and ascites will be randomly assigned, in a 1:1 ratio, to receive one of two methods of therapeutic paracentesis. A stratified randomization method, with maximum creatinine and IAP values as strata, will homogenize patient baseline characteristics before trial group allocation, within 24 h of admission. In the control group, LVP will be performed intermittently according to clinical practice, with a maximum duration of 8 h, while, in the intervention group, continuous passive paracentesis will drain ascitic fluid for up to 7 days. The primary endpoint is serum creatinine concentration, and secondary endpoints include IAP, measured creatinine clearance, daily urine output, stage 3 acute kidney injury and multiorgan dysfunction assessed at day 7 after enrollment, as well as 28-day mortality rate and renal replacement therapy-free days, and length-of-stay. Prespecified values will be used in case of renal replacement therapy or, beforehand ICU discharge, liver transplant and death. Safety analysis will include paracentesis-related complication rate and harm. Data will be analyzed with an intention-to-treat approach. DISCUSSION: This is the first trial to compare the impact of different therapeutic paracentesis strategies on organ dysfunction and outcomes in the prevention and treatment of IAH in critically ill patients with cirrhosis and ascites.

Intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) are underrecognized entities in patients of acute pancreatitis (AP). IAH develops in 30% to 60% and ACS in 15% to 30% of all AP patients and they are markers of severe disease with high morbidity and mortality. The detrimental effect of increased IAP has been recognized in several organ systems, including the central nervous system, cardiovascular, respiratory, renal and gastrointestinal systems. The pathophysiology of IAH/ACS development in patients with AP is multifactorial. Pathogenetic mechanisms include over-zealous fluid management, visceral edema, ileus, peripancreatic fluid collections, ascites and retroperitoneal edema. Laboratory and imaging markers are neither sensitive nor specific enough to detect IAH/ACS and intra-abdominal pressure (IAP) monitoring is vital for early diagnosis and the management of patients of AP with IAH/ACS. The treatment of IAH/ACS requires a multi-modality approach with both medical and surgical attention. Medical management consists of nasogastric/rectal decompression, prokinetics, fluid management and diuretics or hemodialysis. If conservative management is not effective, percutaneous drainage of fluid collection or ascites is necessary. Despite medical management, if IAP worsens, surgical decompression is warranted. The review discusses the relevance of IAH/ACS in patients of AP and its management.

Ruptured abdominal aortic aneurysms (rAAA), with or without iliac involvement, are a life-threatening scenario with high mortality even after surgical therapy. Several factors have contributed to improving perioperative outcomes in recent years, including the progressive use of endovascular aortic repair (EVAR) and intraoperative balloon occlusion of the aorta, a dedicated treatment algorithm with centralization of care to high-volume centres, and optimized perioperative management protocols. Nowadays, EVAR is applicable in the majority of scenarios even in the emergency setting. Among the factors that influence the postoperative course of rAAA patients, abdominal compartment syndrome (ACS) is a rare but life-threatening complication. As its early clinical diagnosis is often missed but crucial to initiate an emergent surgical decompression therapy, dedicated surveillance protocols and transvesical measurement of the intraabdominal pressure are key for prompt diagnosis and immediate treatment of ACS. Further improvement of rAAA patients' outcome may be achieved by the implementation of simulation-based training (of both technical and non-technical skills for surgeons as well as all involved healthcare personnel in multidisciplinary teams) and by transfer of all rAAA patients to specialized vascular centres with advanced experience and high caseload.

BACKGROUND: Intra-abdominal hypertension is a comorbid condition in critically ill children, is an independent predictor of mortality, and has harmful effects on multiple organ systems through renal, pulmonary or hemodynamic damage. Intra-abdominal pressure monitoring is widely used in clinical practice because it is a safe, accurate, inexpensive, and rapid method for the clinical diagnosis of intra-abdominal hypertension. OBJECTIVE: To improve pediatric critical care nurses' understanding of and ability to perform intra-abdominal pressure monitoring and provide a reference for standardizing intra-abdominal pressure monitoring in clinical practice. METHODS: A literature review was performed using the following keywords: intra-abdominal pressure, bladder pressure, vesicular pressure, measurement, monitoring, critically ill children, pediatric intensive care, pediatric, and children. Four hundred fifty-four articles were initially identified and screened; 24 were included. RESULTS: The monitoring and management of intra-abdominal pressure should include appropriate and clinically proven intra-abdominal pressure measurement techniques, appropriate patients, the proper frequency of measurement, and a repeatable intra-abdominal pressure measurement method. CONCLUSIONS: Knowledge of intra-abdominal pressure monitoring in critically ill children enhances the ability of nurses in clinical practice to accurately measure intra-abdominal pressure to improve the timeliness and accuracy of clinical identification of intra-abdominal hypertension and guide decompression interventions.

BACKGROUND: Constantly elevated intra-abdominal pressure (IAH) can lead to abdominal compartment syndrome (ACS), which is associated with organ dysfunction and even multiorgan failure. Our 2010 survey revealed an inconsistent acceptance of definitions and guidelines among pediatric intensivists regarding the diagnosis and treatment of IAH and ACS in Germany. This is the first survey to assess the impact of the updated guidelines on neonatal/pediatric intensive care units (NICU/PICU) in German-speaking countries after WSACS published those in 2013. METHODS: We conducted a follow-up survey and sent 473 questionnaires to all 328 German-speaking pediatric hospitals. We compared our findings regarding awareness, diagnostics and therapy of IAH and ACS with the results of our 2010 survey. RESULTS: The response rate was 48% (n = 156). The majority of respondents was from Germany (86%) and working in PICUs with mostly neonatal patients (53%). The number of participants who stated that IAH and ACS play a role in their clinical practice rose from 44% in 2010 to 56% in 2016. Similar to the 2010 investigations, only a few neonatal/pediatric intensivists knew the correct WSACS definition of an IAH (4% vs 6%). Different from the previous study, the number of participants who correctly defined an ACS increased from 18 to 58% (p < 0,001). The number of respondents measuring intra-abdominal pressure (IAP) increased from 20 to 43% (p < 0,001). Decompressive laparotomies (DLs) were performed more frequently than in 2010 (36% vs. 19%, p < 0,001), and the reported survival rate was higher when a DL was used (85% ± 17% vs. 40 ± 34%). CONCLUSIONS: Our follow-up survey of neonatal/pediatric intensivists showed an improvement in the awareness and knowledge of valid definitions of ACS. Moreover, there has been an increase in the number of physicians measuring IAP in patients. However, a significant number has still never diagnosed IAH/ACS, and more than half of the respondents have never measured IAP. This reinforces the suspicion that IAH and ACS are only slowly coming into the focus of neonatal/pediatric intensivists in German-speaking pediatric hospitals. The goal should be to raise awareness of IAH and ACS through education and training and to establish diagnostic algorithms, especially for pediatric patients. The increased survival rate after conducting a prompt DL consolidates the impression that the probability of survival can be increased by timely surgical decompression in the case of full-blown ACS.

INTRODUCTION: Abdominal compartment syndrome (ACS) is the presence of intra-abdominal hypertension with systemic, multiorgan effects and is associated with high mortality, yet the national incidence and mortality rates of pediatric ACS remain unknown. The aim of this study is to evaluate the incidence and mortality of pediatric ACS over a 13-year period across multiple children's hospitals and between individual children's hospitals in the United States. METHODS: We performed a retrospective cohort study on children (aged < 18 y) with ACS in the Pediatric Health Information Systems database from 2007 to 2019. We identified ACS patients by International Classification of Diseases codes in the ninth and 10th revision. The primary outcomes were incidence and mortality, which were analyzed by year, age, and hospital of admission. RESULTS: Across 49 children's hospitals, we identified 2887 children with ACS from 2007 to 2019 in the Pediatric Health Information Systems database. The overall incidence of ACS was 0.17% and the overall mortality was 48.87%. There was no significant difference in annual incidence (P = 0.12) or mortality (P = 0.39) over the study period. There was no difference in incidence across age group (P = 0.38); however, mortality in patients 0-30 d old (58.61%) was significantly higher than older age groups (P < 0.0001). The hospital-specific incidence (0.04%-0.46%) and mortality (28.57%-71.43%) varied widely. CONCLUSIONS: The annual incidence and mortality of pediatric ACS are unchanged from 2007 to 2019. ACS mortality remains high, especially in neonatal intensive care unit patients. No obvious correlation is seen between incidence rates and mortality. Differing hospital-specific incidence and mortality could suggest inconsistencies between institutions that affect pediatric ACS care, perhaps with respect to recognition and diagnosis.

Intra-abdominal hypertension (IAH) is frequently present in the critically ill and is associated with increased morbidity and mortality. Conventionally, intermittent 'spot-check' manual measurements of bladder pressure in those perceived as high risk are used as surrogates for intra-abdominal pressure (IAP). True patterns of IAH remain unknown. We explored the incidence of IAH in cardiac surgery patients and describe the intra-and postoperative course of IAP using a novel, high frequency, automated bladder pressure measurement system. Sub-analysis of a prospective, multicenter, observational study (NCT04669548) conducted in three large academic medical centers. Continuous urinary output (CUO) and IAP measurements were observed using the Accuryn Monitoring System (Potrero Medical, Hayward, CA). Data collected included demographics, hemodynamic support, and high-frequency IAP and CUO. One Hundred Thirty-Seven cardiac surgery patients were analyzed intraoperatively and followed 48 h postoperatively in the intensive care unit. Median age was 66.4 [58.3, 72.0] years, and 61% were men. Median Foley catheter dwell time was 56.0 [46.8, 77.5] hours, and median baseline IAP was 6.3 [4.0, 8.1] mmHg. 93% (128/137) of patients were in IAH grade I, 82% (113/137) in grade II, 39% (53/137) in grade III, and 5% (7/137) in grade IV for at least 12 cumulative hours. For maximum consecutive duration of IAH, 84% (115/137) of patients spent at least 12 h in grade I, 62% (85/137) in grade II, 18% (25/137) in grade III, and 2% (3/137) in grade IV IAH. During the first 48 h after cardiac surgery, IAH is common and persistent. Improved and automated monitoring of IAP will increase the detection of IAH-which normally would remain undetected using traditional intermittent monitoring methods.

Abdominal compartment syndrome (ACS) in children is a neglected complication in the pediatric intensive care unit (PICU) because the onset is insidious. ACS develops rapidly, involves the systemic organs, has a high mortality, and is a very serious complication in PICU. Timely and effective treatment of children with suspected or confirmed ACS is of significance to prevent the progression of the disease, improve prognosis and reduce mortality. However, most clinicians have limited understanding of the treatment measures for children with ACS and are unable to correctly choose appropriate treatment strategies, which affect the prognosis of children. To make the optimal treatment plan for ACS in children, the extent of elevated intra-abdominal pressure, the degree of organ dysfunction and the underlying diseases should be considered comprehensively. Mechanical ventilation, continuous renal replacement therapy (CRRT), and extracorporeal membrane oxygenation (ECMO) have a bidirectional effect on the occurrence and therapeutic effect of ACS. On the one hand, this article reviews the individualized treatment of ACS in PICU, so that more pediatricians could have a comprehensive and clear systematic understanding of the treatment plan of ACS in children. On the other hand, special treatment strategies and prognoses of ACS in PICU were also reviewed in this article, and the effects of intra-abdominal hypertension (IAH) on mechanical ventilation parameters, ECMO, and CRRT were illuminated. As well as the management strategy of mechanical ventilation, CRRT type in ACS children, and the treatment of ACS during ECMO were revealed.

INTRODUCTION: This study aimed to evaluate the current awareness and management of intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) among paediatric intensivists. MATERIAL AND METHODS: A web-based electronic survey was sent to all physicians working in paedia-tric intensive care units (PICUs) in Saudi Arabia. The survey questions obtained information regarding awareness of ACS and IAH, recognition criteria, monitoring of intra-abdominal pressure (IAP), and experience in managing ACS. RESULTS: A total of 79 physicians responded to the survey (response rate: 53%). Among respondents 48% were consultants. 85% of respondents were familiar with IAP/IAH/ACS. Only 35% and 10% were aware of the Abdominal Compartment Society consensus definitions for IAH and ACS in the paediatric population, respectively. Most respondents considered the cut-off for IAH to be ≥ 15 mm Hg, and approximately two-thirds thought that the cut-off for ACS was higher than the currently suggested consensus definition (10 mm Hg). More than two-thirds of respondents monitored IAP in the PICU, and it was measured almost exclusively via the bladder (96%); the majority (70%) reported that they instilled volumes well above the current recommendations. Medical management was the most frequent therapeutic approach to treat IAH/ACS, while surgical decompression was the least attempted option. Decisions to decompress the abdomen were predominantly based on the presence of organ dysfunction (74.4%). CONCLUSIONS: This survey showed that although most responding physicians claim to be familiar with IAH and ACS, their knowledge of published consensus definitions, measurement techniques, and clinical management must be updated.

In critically ill patients an intra-abdominal hypertension (IAH) is a frequent phenomenon. An IAH is defined as an intra-abdominal pressure (IAP) persistently ≥â¯12â¯mmâ¯Hg and an abdominal compartment syndrome is defined as an IAP with a persistent pressure ≥â¯20â¯mmâ¯Hg in combination with newly occurring organ failure. The bladder pressure serves as a surrogate parameter for the IAP, which should be measured noninvasively in a standardized manner. An undetected and untreated IAH worsens the prognosis of critically ill patients.
