Intra-abdominal Hypertension and the Open Abdomen: Nursing Guidelines From the Abdominal Compartment Society.

Intra-abdominal hypertension has been identified as an independent risk factor for death in critically ill patients. Known risk factors for intra-abdominal hypertension indicate that intra-abdominal pressures should be measured and monitored. The Abdominal Compartment Society has identified medical and surgical interventions to relieve intra-abdominal hypertension or to manage the open abdomen if abdominal compartment syndrome occurs. The purpose of this article is to describe assessments and interventions for managing intra-abdominal hypertension and open abdomen that are within the scope of practice for direct-care nurses. These guidelines provide direction to critical care nurses caring for these patients.

MI: Not a Heart Attack but a Gut Attack.

Mesenteric ischemia and infarction are infrequent but often deadly conditions in acute and critically ill patients. Mesenteric ischemia may be a primary admission diagnosis or may develop secondary to another diagnosis. Having a high index of suspicion for patients at risk of mesenteric ischemia and mesenteric infarction can alter a poor outcome. This article reviews the pathophysiology, risk factors, assessment, medical and nursing diagnoses, as well as collaborative management for mesenteric ischemia. Early identification of patients at risk and the appropriate diagnostic testing are stressed. Nurses armed with the knowledge of this condition are better able to provide safe care to their patients.

The effects of nursing activities on the intra-abdominal pressure of patients at risk for intra-abdominal hypertension.

BACKGROUND: Intra-abdominal hypertension (IAH) occurs frequently in critically ill patients, and adds to their morbidity and mortality. There is no published evidence on the effects of nursing activities on the intra-abdominal pressure (IAP) for patients at risk of IAH. The purpose of this study was to identify the effects of hygiene care on the IAP of patients at risk for IAH. METHODS: Hygiene care was provided to 34 at-risk patients. IAP was measured prior to initiating the hygiene care, immediately after and 10 minutes later. This was a quasi-experimental, pre-test/ post-test design. RESULTS: The 10 minute post-hygiene care measurement of the IAP was significantly lower than the pre or immediate post-measurement of the IAP. There were no significant changes in the mean arterial pressure (MAP) or the abdominal perfusion pressure (APP). CONCLUSIONS: It is safe and possibly therapeutic to provide hygiene care to patients at risk for IAH.

Upgrading the American Association of Critical-Care Nurses' evidence-leveling hierarchy.

In August 2008, the American Association of Critical-Care Nurses' (AACN's) Evidence-Based Practice Resource Work Group met to review current AACN Practice Alerts and to identify new Practice Alerts to be created. The work group was also tasked with reassessment of the grading system used by AACN that evaluates evidence associated with the Practice Alerts and other AACN resources. This article details the effort of this national volunteer work group, specifically highlighting the development of the new AACN evidence-leveling hierarchy system.
