Optimization of kidney function in cardiac surgery patients with intra-abdominal hypertension: expert opinion.

Cardiac surgery-associated acute kidney injury (CSA-AKI) affects up to 42% of cardiac surgery patients. CSA-AKI is multifactorial, with low abdominal perfusion pressure often overlooked. Abdominal perfusion pressure is calculated as mean arterial pressure minus intra-abdominal pressure (IAP). IAH decreases cardiac output and compresses the renal vasculature and renal parenchyma. Recent studies have highlighted the frequent occurrence of IAH in cardiac surgery patients and have linked the role of low perfusion pressure to the occurrence of AKI. This review and expert opinion illustrate current evidence on the pathophysiology, diagnosis, and therapy of IAH and ACS in the context of AKI.

Should we perform decompressive laparotomy during severe acute pancreatitis with intra-abdominal hypertension below 25 mmHg: Only the gut knows.

We suggest that during severe acute pancreatitis (SAP) with intra-abdominal hypertension, practitioners should consider decompressive laparotomy, even with intra-abdominal pressure (IAP) below 25 mmHg. Indeed, in this setting, non-occlusive mesenteric ischemia (NOMI) may occur even with IAP below this cutoff and lead to transmural necrosis if abdominal perfusion pressure is not promptly restored. We report our experience of 18 critically ill patients with SAP having undergone decompressive laparotomy of which one third had NOMI while IAP was mostly below 25 mmHg.

The Effect of Breast Milk Odor on Feeding Cues, Transition Time to Oral Feeding, and Abdominal Perfusion in Premature Newborns: A Randomised Controlled Trial.

PURPOSE: The present study was conducted to determine the effect of odor stimulation with breast milk (BM) applied to premature newborns before and during enteral feeding on feeding cues, transition time to oral feeding and abdominal perfusion. DESIGN: This study was a parallel group pretest-post test randomised controlled trial (RCT). METHODS: The study was conducted in the neonatal intensive care unit (NICU) in Türkiye. Study data were collected from 32 premature newborns between October 2020 and December 2021. Newborns were randomly assigned to either intervention (n = 16) or control (n = 16) groups. Odor stimulation with BM was applied to newborns in the intervention group (IG) before and during enteral feeding for 3 days. Data were collected with the Newborn Information Form, Abdominal Perfusion Follow-up Form, and Feeding Cues Follow-up Form. Yates corrected and Fisher chi-squared test, Mann-Whitney U test, Cohen Kappa statistics, Permanova analysis, and Wilcoxon test were used in the analysis. The study was registered in ClinicalTrials.gov (NCT04843293). RESULTS: The frequency of feeding cues in newborns who were exposed to the odor of BM, was higher than in the control group (CG) (p < .05). The transition times to oral feeding were similar in newborns in the IG and CG (p > .05). Abdominal perfusion level of newborns in the IG was higher than the CG (p < .05), and the level of abdominal perfusion showed a significant difference in terms of group*time interaction (p < .05). CONCLUSION: Our findings suggest that odor stimulation with BM will be beneficial in improving the digestive functions of premature newborns.

Continuous passive paracentesis versus large-volume paracentesis in the prevention and treatment of intra-abdominal hypertension in the critically ill cirrhotic patient with ascites (COPPTRIAHL): study protocol for a randomized controlled trial.

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. TRIAL REGISTRATION: ClinicalTrials.gov NCT04322201 . Registered on 20 December 2019.

ABDOMINAL PERFUSION PRESSURE IN PREDICTION OF THE TERMS OF ACUTE NECROTIZING PANCREATITIS INFECTION.

OBJECTIVE: The aim: To determine the role of the abdominal perfusion pressure level at the beginning of the disease in predicting the timing of infection of acute nec¬rotizing pancreatitis. PATIENTS AND METHODS: Materials and methods: A retrospective cross-sectional single-center study of 39 patients with acute severe pancreatitis (ASP) and pancreatic infection (PI) with measured and calculated minimal abdominal perfusion pressure (APP) in the first 48 hours of the disease. The existence of a correlation between the onset of PI and the level of intra-abdominal (IAP) and abdominal perfusion pressure was calculated and a single-factor mathematical model of linear regression was built. RESULTS: Results: A negative strong correlation was found between IAP and the timing of PI onset, ρ=-0.818 (p<0.001), and a positive strong correlation was found between APP and the timing of PI onset, ρ=0.933 (p<0.001). The dependence of the outcome variable (PI term) on the APP value was revealed, adjusted coefficient of determination R²adj = 0.887 was corrected, F value 288.5, p<0.001, root mean square errors RSE = 1.31 (with 37 degrees of freedom). The value of the coefficient X1 was 0.47±0.0, p<0.001. CONCLUSION: Conclusions: An increase in IAP in the first 48 hours of the desease in patients with ASP was, on average, accompanied by a reduction in the start of PI. A decrease in APP in the first 48 hours of the desease in patients with ASP was, on average, accompanied by a reduction in the start of PI. In the study sample, it was possible to predict the time of PI initiation by measuring the APP level in the first 48 hours of the disease with a margin of error for 1.3 days. It was found that with a decrease in the APP level, the time of the PI occurrence was reduced (p<0.001), on average, by 0.47±0.02 days for each mm Hg of APP.

Intra-Abdominal Hypertension and Compartment Syndrome after Pediatric Liver Transplantation: Incidence, Risk Factors and Outcome.

In pediatric liver transplantation (pLT), the risk for the manifestation and relevance of intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) is high. This observational study aimed to evaluate the incidence, relevance and risk factors for IAH and ACS by monitoring the intra-abdominal pressure (IAP), macro- and microcirculation (near-infrared spectroscopy (NIRS)), clinical and laboratory status and outcomes of 27 patients (16 female) after pLT (median age at pLT 35 months). Of the patients, 85% developed an elevated IAP, most of them mild. However, 17% achieved IAH° 3, 13% achieved IAH° 4 and 63% developed ACS. A multiple linear regression analysis identified aortal hepatic artery anastomosis and cold ischemia time (CIT) as risk factors for increased IAP and longer CIT and staged abdominal wall closure for ACS. ACS patients had significantly longer mechanical ventilation (p = 0.004) and LOS-PICU (p = 0.003). No significant correlation between NIRS or biliary complications and IAH or ACS could be shown. IAH and ACS after pLT were frequent. NIRS or grade of IAH alone should not be used for monitoring. A longer CIT is an important risk factor for higher IAP and ACS. Therefore, approaches such as the ex vivo machine perfusion of donor organs, reducing CIT effects on them, have great potential. Our study provides important basics for studying such approaches.

Pancreatic Cancer: Challenges and Opportunities in Locoregional Therapies.

Pancreatic cancer (PC) remains the seventh leading cause of cancer-related deaths worldwide and the third in the United States, making it one of the most lethal solid malignancies. Unfortunately, the symptoms of this disease are not very apparent despite an increasing incidence rate. Therefore, at the time of diagnosis, 45% of patients have already developed metastatic tumours. Due to the aggressive nature of the pancreatic tumours, local interventions are required in addition to first-line treatments. Locoregional interventions affect a specific area of the pancreas to minimize local tumour recurrence and reduce the side effects on surrounding healthy tissues. However, compared to the number of new studies on systemic therapy, very little research has been conducted on localised interventions for PC. To address this unbalanced focus and to shed light on the tremendous potentials of locoregional therapies, this work will provide a detailed discussion of various localised treatment strategies. Most importantly, to the best of our knowledge, the aspect of localised drug delivery systems used in PC was unprecedentedly discussed in this work. This review is meant for researchers and clinicians considering utilizing local therapy for the effective treatment of PC, providing a thorough guide on recent advancements in research and clinical trials toward locoregional interventions, together with the authors' insight into their potential improvements.

Therapeutic Effect of Regional Chemotherapy in Diffuse Metastatic Cholangiocarcinoma.

BACKGROUND: Current therapeutic options in diffuse metastatic cholangiocarcinoma (CCC) are limited with unsatisfactory results. We evaluated the efficacy of regional chemotherapy (RegCTx) using arterial infusion (AI), hypoxic stop-flow abdominal perfusion (HAP), upper abdominal perfusion (UAP) and isolated-thoracic perfusion (ITP) in 36 patients with metastatic perihilar and intrahepatic CCC. METHODS: Ten patients had previously undergone a liver resection and in 14 patients the previous systemic chemotherapy (sCTx) approach had failed. A total of 189 RegCTx cycles (90 AI, 74 UAP, 13 HAP and 12 ITP) were applied using cisplatin alone or with Adriamycin and Mitomycin C. A minimum of three cycles were applied in 75% of the study population. The response was evaluated using RECIST criteria with MediasStat 28.5.14. Mortality, morbidity and survival analysis were performed using a prospective follow-up database and SPSS-28.0. RESULTS: No procedure related mortality occurred. The overall morbidity was 56% and dominated by lymph fistulas at the inguinal access site. No grade III or IV haematological complication occurred. The overall response rate was 38% partial response, 41% stable and 21% progressive disease. Median overall survival was 23 months (95%CI 16.3-29.7). The RegCTx specific survival was 12 months (95%CI 6.5-17.5) in completely therapy naive patients but also in patients who had failed a sCTx attempt previously. CONCLUSION: RegCTx is feasible, safe and superior to the current proposed therapeutic options in metastatic CCC. The role of RegCTx should be determined in a larger cohort of diffuse metastatic CCC patients but also at early stages especially in initially not resectable but potentially resectable patients.

Elevated intra-abdominal pressure: A review of current knowledge.

Elevated intra-abdominal pressure (IAP) is a known cause of increased morbidity and mortality among critically ill patients. Intra-abdominal hypertension (IAH) and abdominal compartment syndrome can lead to rapid deterioration of organ function and the development of multiple organ failure. Raised IAP affects every system and main organ in the human body. Even marginally sustained IAH results in malperfusion and may disrupt the process of recovery. Yet, despite being so common, this potentially lethal condition often goes unnoticed. In 2004, the World Society of the Abdominal Compartment Syndrome, an international multidisciplinary consensus group, was formed to provide unified definitions, improve understanding and promote research in this field. Simple, reliable and nearly costless standardized methods of non-invasive measurement and monitoring of bladder pressure allow early recognition of IAH and timely optimized management. The correct, structured approach to treatment can have a striking effect and fully restore homeostasis. In recent years, significant progress has been made in this area with the contribution of surgeons, internal medicine specialists and anesthesiologists. Our review focuses on recent advances in order to present the complex underlying pathophysiology and guidelines concerning diagnosis, monitoring and treatment of this life-threatening condition.

Duodenum edema due to reduced lymphatic drainage leads to increased inflammation in a porcine endotoxemic model.

BACKGROUND: Interventions, such as mechanical ventilation with high positive end-expiratory pressure (PEEP), increase inflammation in abdominal organs. This effect could be due to reduced venous return and impaired splanchnic perfusion, or intestinal edema by reduced lymphatic drainage. However, it is not clear whether abdominal edema per se leads to increased intestinal inflammation when perfusion is normal. The aim of the presented study was to investigate if an impaired thoracic duct function can induce edema of the abdominal organs and if it is associated to increase inflammation when perfusion is maintained normal. In a porcine model, endotoxin was used to induce systemic inflammation. In the Edema group (n = 6) the abdominal portion of the thoracic duct was ligated, while in the Control group (7 animals) it was maintained intact. Half of the animals underwent a diffusion weighted-magnetic resonance imaging (DW-MRI) at the end of the 6-h observation period to determine the abdominal organ perfusion. Edema in abdominal organs was assessed using wet-dry weight and with MRI. Inflammation was assessed by measuring cytokine concentrations in abdominal organs and blood as well as histopathological analysis of the abdominal organs. RESULTS: Organ perfusion was similar in both groups, but the Edema group had more intestinal (duodenum) edema, ascites, higher intra-abdominal pressure (IAP) at the end of observation time, and higher cytokine concentration in the small intestine. Systemic cytokines (from blood samples) correlated with IAP. CONCLUSIONS: In this experimental endotoxemic porcine model, the thoracic duct's ligation enhanced edema formation in the duodenum, and it was associated with increased inflammation.

Role of normothermic perfusion with ECMO in donation after controlled cardiac death in Spain.

Spain has become one of the most active countries in donation after controlled cardiac death, using normothermic abdominal perfusion with ECMO in more than 50% of all donors - a situation contributed to by the creation of mobile teams to support hospitals lacking this technology. The donation process must be respectful of the wishes and values of the patients and their relatives, especially if there is pre mortem manipulation, and the absence of cerebral perfusion should be guaranteed. The liver is the most benefited organ by reducing biliary complications as well as the loss of grafts. In renal transplantation, the technique could contribute to reduce the incidence of delayed graft function. In addition, the procedure is compatible with surgical rapid recovery in hypothermia when there is also lung donation. The future lies in the consolidation of cardiac donation by extending normothermic perfusion to the thoracic cavity.

Efficacy of Regional Chemotherapy Approach in Peritoneal Metastatic Gastric Cancer.

Peritoneal spread is frequent in gastric cancer (GC) and a palliative condition. After failure to systemic chemotherapy (sCTx) remaining therapeutic options are very limited. We evaluated the feasibility and efficacy of locoregional chemotherapy (RegCTx) in peritoneal metastatic GC. In total, 38 (23 male and 15 female) patients with peritoneal metastatic GC after failure of previous sCTx and unresectable disease were enrolled in this study. Using the hypoxic abdominal stop-flow perfusion, upper abdominal perfusion and intraarterial infusion technique in total 114 cycles with Cisplatin, Adriamycin and Mitomycin C were applied. No significant procedure related toxicity was noticed- especially no Grade 3 or 4 toxicity occurred. With the RegCTx approach a median overall survival of 17.4 months was achieved. Patients who had undergone previously resection of the GC the median overall survival was even better with 23.5 months. RegCTx is a promising, safe and efficient approach in diffuse metastatic GC. The evaluation of RegCTx in the setting of multimodal treatment approach at less advanced stages is also warranted.

Deepening of sedation with propofol has limited effect on intra-abdominal pressure - An interventional study in mechanically ventilated adult patients with intra-abdominal hypertension.

PURPOSE: To evaluate the effect of deepening of sedation on intra-abdominal pressure (IAP). METHODS: 37 adult mechanically ventilated ICU patients with intra-abdominal hypertension received a bolus dose and subsequent infusion of propofol (bolus: 1 mg/kg, infusion: 3 mg/kg/h). IAP, mean arterial pressure (MAP), abdominal perfusion pressure (APP), depth of sedation according to Richmond Agitation-Sedation Scale (RASS), respiratory parameters, and vasopressor dose were assessed after bolus and at 15, 30 and 60 min of infusion of propofol. RESULTS: Median IAP at baseline was 15 (13-16) mm Hg. During the intervention, median IAP decreased by 1 mm Hg at all time points. In 24% of patients IAP decreased by ≥3 mm Hg. Compared to baseline, MAP and APP were reduced at all time points. Deepening of sedation per RASS was achieved in 70% of patients at all time points. No changes in respiratory tidal volumes nor plateau pressures were observed. Vasopressor therapy with noradrenaline was started or increased in 43% of patients, whereas the increase in patients already receiving noradrenaline prior to the intervention was not significant. CONCLUSIONS: Deepening of sedation with propofol results in a small decrease in IAP and greater simultaneous decrease in MAP and APP, requiring increased vasopressor support in some cases.

Intraoperative fluid therapy for video-assisted ovariohysterectomy in dogs.

BACKGROUND: Intraoperative fluids are still poorly studied in veterinary medicine. In humans the dosage is associated with significant differences in postoperative outcomes. OBJECTIVES: The aim of this study is to verify the influence of three different fluid therapy rates in dogs undergoing video-assisted ovariohysterectomy. METHODS: Twenty-four female dogs were distributed into three groups: G5, G10, and G20. Each group was given 5, 10, and 20 mL·kg-1·h-1 of Lactate Ringer, respectively. This study evaluated the following parameters: central venous pressure, arterial blood pressure, heart rate, respiratory rate, temperature, acid-base balance, and serum lactate levels. Additionally, this study evaluated the following urinary variables: urea, creatinine, protein to creatinine ratio, urine output, and urine specific gravity. The dogs were evaluated up to 26 h after the procedure. RESULTS: All animals presented respiratory acidosis during the intraoperative period. The G5 group evidenced intraoperative oliguria (0.80 ± 0.38 mL·kg-1·h-1), differing from the G20 group (2.17 ± 0.52 mL·kg-1·h-1) (p = 0.001). Serum lactate was different between groups during extubation (p = 0.036), with higher values being recorded in the G5 group (2.19 ± 1.65 mmol/L). Animals from the G20 group presented more severe hypothermia at the end of the procedure (35.93 ± 0.61°C) (p = 0.032). Only the members of the G20 group presented mean potassium values below the reference for the species. Anion gap values were lower in the G20 group when compared to the G5 and G10 groups (p = 0.017). CONCLUSIONS: The use of lactated Ringer's solution at the rate of 10 mL·kg-1·h-1 seems to be beneficial in the elective laparoscopic procedures over the 5 or 20 mL·kg-1·h-1 rates of infusion.

Hypoxic isolated abdominal perfusion breaks through chemoresistance in recurrent FIGO stage IIIC and IV ovarian cancer.

To overcome drug resistance in relapsed ovarian cancer, an isolated perfusion system was used to generate a higher local exposure to cytostatic drugs. In addition to cisplatin as the cytostatic agent of choice, the present study combined adriamycin and mitomycin in a three drugs regime due to their increased cytotoxicity under hypoxia. A total of 107 patients, including 87 patients with relapses after previous platinum-containing therapies, 46 stage IIIC and 41 stage IV cases, were enrolled in the present study. A total of 25 patients were chemonaive, including 20 stage IIIC. The systemically pretreated patients in stage IIIC survived a median of 12.8 months, and those in stage IV 10.9 months. The overall clinical response rate of stages IIIC and IV combined was 69%. A complete decrease in ascites was found in 43% of all patients, a significant reduction in 19%. Toxicity and side effects were very mild and the bone marrow suppression was mostly grade I and never exceeded grade II. The primary clinical symptom in patients with post-therapeutic tumor necrosis, which occurred in 10-15% of all cases, was fever, fatigue and poor performance. The isolated hypoxic abdominal perfusion treatment is a potent instrument to break an existing chemoresistance without significant side effects with a good quality of life and comparatively long survival time.

The influence of Transversus Abdominis Muscle Release (TAR) for complex incisional hernia repair on the intraabdominal pressure and pulmonary function.

INTRODUCTION: Among many other techniques for Abdominal Wall Reconstruction (AWR), posterior component separation with Transversus Abdominis Release (TAR), continues to gain popularity and it is increasingly used with promising long-term results. Our goal was to evaluate the influence of TAR with mesh retromuscular reinforcement on the intra-abdominal pressure (IAP) and respiratory function in a series of patients with complex incisional hernias (IH). METHODS: Since November 2014 through February 2019, patients with TAR were identified in the Clinical Department of Surgery database and were retrospectively reviewed. Outcome measures include: demographics, pre- and perioperative details, preoperative and postoperative IAP and plateau pressure (PP). RESULTS: One-hundred-and-one consecutive TAR procedures (19.7% from all incisional hernia repairs) were analyzed. Mean age was 63 years with a mean Body Mass Index (BMI) of 31.85 kg/m2 (25-51). Diabetes and Chronic Obstructive Pulmonary Disease (COPD) were the main major comorbidities. Mean hernia defect area was 247 cm2 (104-528 cm2). CONCLUSION: TAR is a safe and sound procedure with acceptable modifications of the IAP morbidity and recurrence rate when correctly performed on the right patient.

A Pilot Study of the Predictive Potential of Chemosensitivity and Gene Expression Assays Using Circulating Tumour Cells from Patients with Recurrent Ovarian Cancer.

Circulating tumour cells (CTCs) from liquid biopsies are under current investigation in several cancers, including epithelial ovarian cancer (EOC) but face significant drawbacks in terms of non-standardised methodology, low viable cell numbers and accuracy of CTC identification. In this pilot study, we report that chemosensitivity assays using liquid biopsy-derived metastatic EOC CTCs, from 10 patients, nine with stage IIIC and one with stage IV disease, in progression after systemic chemotherapy, submitted for hypoxic isolated abdominal perfusion (HAP), are both feasible and useful in predicting response to therapy. Viable metastatic EOC CTCs (>5 cells/mL for all 10 blood samples), enriched by transient culture and identified by reverse transcription polymerase chain reaction (RT-PCR) and indirect immunofluorescence (IF), were subjected to flow cytometry-based Annexin V-PE assays for chemosensitivity to several chemotherapeutic agents and by RT-PCR for tumour gene expression profiling. Using a cut-off value of >80% cell death, CTC chemosensitivity tests were predictive of patient RECIST 1.1 responses to HAP therapy associated with 100% sensitivity, 50% specificity, 33% positive predictive, 100% negative predictive and 60% accuracy values. We propose that the methodology employed in this study is feasible and has the potential to predict response to therapy, setting the stage for a larger study.

Intra-abdominal Pressure Screening of Horses With Colic.

The objective of this study was to evaluate changes in intra-abdominal pressure (IAP) in horses with colic by associating the underlying etiologies with directly acquired IAP values and survival rate. This is a 2-year cohort study (2014-2016). Horses with clinical signs of colic were admitted to the veterinary teaching hospital during the period 2014-2016. Twenty-eight horses, of different breeds, males (stallions and geldings) and females, aged between 2 and 20 years, and weighing from 300 to 450 kg presenting with clinical signs of colic, were included in the study. IAP was directly acquired at the right flank (standing under sedation) and at the linea alba (supine position under general anesthesia). Twenty IAP measurements were recorded at end expiration for each recording site. IAP values >0.0 mmHg, obtained at the upper right flank in the standing position, were associated with surgical treatment (P < .05). In these cases, signs of colic were associated with strangulated obstructions of the large colon, and a greater likelihood of death as a result of colic (P < .001). Intra-abdominal pressure varied considerably in horses with colic, even for the same underlying etiologies. Horses with colic related to strangulating obstructions of the large intestine had IAP >.0 mmHg, at the upper right flank. These horses were also considerably more likely to require surgical intervention (P < .05) and death/euthanasia was more likely in this group of horses (P < .001).

Role of normothermic perfusión with ECMO in donation after controlled cardiac death in Spain. / Papel de la perfusión normotérmica con oxigenación de membrana extracorporea en la donación en asistolia controlada en España.
