Pediatric critical care nurses' experience with abdominal compartment syndrome

Knowledge, attitudes, and practices (KAP) regarding intra-abdominal pressure monitoring among pediatric intensive care nurses: A cross-sectional study

Objectives

This study aimed to assess the knowledge, attitudes, and practices (KAP) and the training requirements of pediatric intensive care nurses regarding intra-abdominal pressure (IAP) monitoring, in order to provide a reference for the development of relevant training programs and operational procedures in clinical practice.

Methods

This descriptive cross-sectional survey was conducted from April 2023 to June 2023. A convenience sample was created by recruiting 212 pediatric intensive care nurses in eight hospitals in Zhejiang Province. A self-developed IAP monitoring KAP assessment tool was used for evaluation, which included knowledge (14 items), attitude (6 items), and practice (8 items), three dimensions, 28 items.

Results

The overall KAP score was 60.73 ± 8.35; the knowledge score was 7.84 ± 2.35, with a scoring rate of 56.0%; the attitude score was 25.16 ± 3.23, with a scoring rate of 83.9%; and the practice score was 28.44 ± 6.46, with a scoring rate of 69.3%. Nurses wh-o have received IAP monitoring training have higher KAP score, knowledge score and practice score than those who have not received it (P < 0.05). Nurses aged ≤ 30 showed better knowledge of IAP monitoring than those aged > 30 (P < 0.05). Among the participants, 55.7% of the nurses believed the current knowledge was insufficient to perform IAP measurement effectively. Difficulty in identifying the high-risk population of intra-abdominal hypertension (IAH) (64.6%), unfamiliarity with the operation process of IAP measurement (55.6%), and unreasonable nurse-patient ratio allocation (52.8%) were the main obstacles for nurses to monitor IAP.

Conclusions

Pediatric intensive care nurses have a positive attitude towards IAP monitoring, but the knowledge level and practical behavior still need to be strengthened. In particular, the knowledge of published consensus definitions, measurement techniques, and frequency for IAP monitoring is inadequate. It is necessary to implement tailored IAP monitoring training based on their training needs and potential obstacles to promote the standardization and scientificity of IAP monitoring.

Hands off Trans-Femoral Venous Intra-Abdominal Pressure Estimates in Children: Results of a Sobering Single-Center Study

BACKGROUND

For a long time, trans-femoral venous pressure (FVP) measurement was considered a simple alternative for estimating intra-abdominal pressure (IAP). Since intravesical [IVP] and intragastric [IGP] pressure measurements are sometimes contraindicated for anatomical and pathophysiological reasons, FVP raised hopes, especially among pediatricians. Pediatric FVP validation studies have never been published; recent results from adult studies cast doubt on their interchangeability. Therefore, we compared for the first time the measurement agreement between FVP and IVP and IGP in children.

MATERIAL AND METHODS

We prospectively compared FVP with IVP and IGP, according to the Abdominal Compartment Society validation criteria. Additionally, we analyzed the agreement as a function of IAP or right heart valve regurgitation and pulmonary hypertension.

RESULTS

In a real-life PICU study design, n = 39 children were included (median age 4.8 y, LOS-PICU 23 days, PRISM III score 11). In n = 660 FVP-IGP measurement pairs, the median IAP was 7 (range 1 to 23) mmHg; in n = 459 FVP-IVP measurement pairs, the median IAP was 6 (range 1to 16) mmHg. The measurement agreement was extremely low with both established methods (FVP-IGP: r² 0.13, mean bias -0.8 ± 4.4 mmHg, limits of agreement (LOA) -9.6/+8.0, percentage error (PE) 55%; FVP-IVP: r² 0.14, bias +0.5 ± 4.2 mmHg, limit of agreement (LOA) -7.9/+8.9, percentage error (PE) 51%). No effect of the a priori defined influencing factors on the measurement agreement could be demonstrated.

CONCLUSIONS

In a study cohort with a high proportion of critically ill children suffering from IAH, FVP did not agree reliably with either IVP or IGP. Its clinical use in critically ill children must therefore be strongly discouraged.

Awareness and diagnosis for intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) in neonatal (NICU) and pediatric intensive care units (PICU) - a follow-up multicenter survey

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.

Physicians' Knowledge of Abdominal Compartment Syndrome and Intra-Abdominal Hypertension in Saudi Arabia: An Online Cross-Sectional Survey Study

Objective

To determine physicians' knowledge of abdominal compartment syndrome and intra-abdominal hypertension in Saudi Arabia.

Methods

A cross-sectional online survey study was conducted on physicians in Saudi Arabia between March and August 2022. A previously developed questionnaire was adapted and used in this study. The survey instrument investigated the knowledge and management of intra-abdominal hypertension and abdominal compartment syndrome among physicians. Logistic regression was used to identify predictors of being knowledgeable about abdominal compartment syndrome and intra-abdominal hypertension.

Results

A total of 266 physicians participated in this study. Around one-fifth (21.8%) the study participants were ICU physicians and 25.0% reported that they practice internal medicine. Intra-abdominal hypertension (IAH) and the impact of increased intra-abdominal pressure (IAP) on organ function were terms that the majority of research participants (70.3%) reported they were familiar with. A similar percentage (73.7%) reported that they are familiar with abdominal compartment syndrome (ACS). Around 43.0% of the study participants reported that they do not know how to measure IAP. The most frequently reported (13.5%) intervention in the treatment of IAH and ACS was the use of inotropes or vasopressors. The study participants showed a weak level of knowledge of ACS and IAH with a median score of 3.00 (IQR: 5.00-2.00), which represents 27.3% of the maximum attainable score. Physicians working at hospitals with 20-50 ICU beds were 41.0% (odds ratio: 0.59 (CI: 0.37-0.96)) less likely to be knowledgeable about intra-abdominal hypertension and abdominal compartment syndrome (p≤0.05).

Conclusion

Physicians demonstrated a low level of IAP and ACS knowledge. To increase the safety of medical practices and enhance clinical outcomes for patients, awareness should be raised about the proper diagnosis and management of IAP and ACS. Future research should focus on developing effective educational strategies to improve physicians' understanding of IAP and ACS.

Awareness and management of intra-abdominal hypertension and abdominal compartment syndrome by paediatric intensive care physicians: a national survey

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.

Current Approach to the Evaluation and Management of Abdominal Compartment Syndrome in Pediatric Patients

Abdominal compartment syndrome is an emergent condition caused by increased pressure within the abdominal compartment. It can be caused by a number of etiologies, which are associated with decreased abdominal wall compliance, increased intraluminal or intraperitoneal contents, or edema from capillary leak or fluid resuscitation. The history and physical examination are of limited utility, and the criterion standard for diagnosis is intra-abdominal pressure measurement, which is typically performed via an intravesical catheter. Management includes increasing abdominal wall compliance, evacuating gastrointestinal or intraperitoneal contents, avoiding excessive fluid resuscitation, and decompressive laparotomy in select cases.

Outcomes in pediatric patients with abdominal compartment syndrome following urgent exploratory laparotomy

BACKGROUND/PURPOSE

Abdominal compartment syndrome (ACS) is a serious condition with high mortality in critically ill children. Our objectives were to characterize the incidence of ACS in pediatric patients who underwent urgent exploratory laparotomy and to compare outcomes of patients with and without ACS.

METHODS

This retrospective review examined pediatric patients (0-18years) who underwent urgent exploratory laparotomy over a 2-year period. Primary outcome was mortality; secondary outcomes were achievement of primary fascial closure and necessity of bowel resection.

RESULTS

One hundred nineteen patients were included, of which 33 (28%) had ACS, with 27 (23%) being primary ACS and 6 (5%) secondary ACS. Twenty-eight-day mortality was higher in the ACS versus non-ACS group (52% versus 0%, p<0.001) and overall hospitalization (64% versus 2%, p<0.001). Primary fascial closure was achieved less often in ACS compared to non-ACS patients (46% versus 98%, p<0.001). Bowel resection was more frequent in ACS versus non-ACS patients, approaching statistical significance (49% versus 30%, p 0.056).

CONCLUSION

During the study period, almost one third of children who underwent urgent exploratory laparotomy had ACS and 64% died. Children undergoing evaluation for acute surgical abdomen may benefit from routine intraabdominal pressure measurement.

Intra-abdominal hypertension and abdominal compartment syndrome in pediatrics. A review

PURPOSE

To consolidate pediatric intensivists' understanding of the pathophysiology, definition, incidence, monitoring, and management of intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS); and to highlight the characteristics related to the pediatric population.

METHODS

This is a narrative review article that utilized a systematic search of the medical literature published in the English language between January 1990 and august 2016. Studies were identified by conducting a comprehensive search of Pub Med databases. Search terms included "intra-abdominal hypertension and child", "intra-abdominal hypertension and pediatrics", "abdominal compartment syndrome and child", and "abdominal compartment syndrome and pediatrics".

RESULTS

Intra-abdominal hypertension and ACS are associated with a number of pathophysiological disturbances and increased morbidity and mortality. These conditions have been well described in critically ill adults. In children, the IAH and the ACS have a reported incidence of 13% and 0.6 to 10% respectively; they carry similar prognostic impact but are still under-diagnosed and under-recognized by pediatric health care providers.

CONCLUSIONS

Intra-abdominal hypertension and ACS are conditions that are regularly encountered in critically ill children. They are associated with an increased morbidity and mortality. Early recognition, prevention and timely management of this critical condition are necessary to improve its outcome.

Recognition and management of intra-abdominal hypertension and abdominal compartment syndrome; a survey among Dutch surgeons

Purpose

Intra-abdominal hypertension (IAH) and Abdominal compartment syndrome (ACS) are relatively rare, but severe complications. Although many advances were made in recent years, the recognition and management remain subject of debate. The aim of this study was to determine the current state of awareness, knowledge and use of evidence-based medicine regarding IAH and ACS among Dutch surgeons.

Methods

A literature-based and expert consensus survey was developed. One surgeon in every hospital in The Netherlands was asked to complete the online questionnaire.

Results

Sixty of 87 (69 %) invited surgeons completed the questionnaire. Intra-abdominal pressure (IAP) was measured using intra-vesical methods by 55 (98 %) respondents. Diuretics (N = 38; 63 %) and laparotomy (N = 33; 55 %) were considered useful treatments for IAH or prevention of ACS by a majority. Only 16 (27 %) respondents used these guidelines in daily practice, and 37 (62 %) respondents are willing to do so. Although 35 (58 %) surgeons agreed that IAH is only a symptom, not requiring treatment. Forty-one percent of experienced respondents suggested that prevalence of ACS remained unchanged. Nearly all respondents (N = 59; 98 %) believed that open abdomen management improves patient outcomes, many (N = 46; 77 %) confirm the high complications rate of this treatment.

Conclusion

The definitions of IAH and ACS and the related diagnostic and therapeutic challenges are relatively well known by Dutch surgeons. Despite limited use of the evidence-based guidelines, the willingness to do so is high. Most respondents favor open abdomen treatment for patients with imminent ACS, despite the high complication rates associated with this treatment.
