Percutaneously introduced wireless intramuscular near-infrared spectroscopy device detects muscle oxygenation changes in porcine model of lower extremity compartment syndrome.

J Orthop Res 2022 Apr 5. Epub 2022 Apr 5.

Division of Plastic and Reconstructive Surgery, Department of Surgery, School of Medicine, Washington University, St. Louis, Missouri, USA.

Serial examination and direct measurement of intracompartmental pressure (ICP) are suboptimal strategies for the detection of acute compartment syndrome (CS) because they are operator-dependent and yield information that only indirectly reflects intracompartmental muscle perfusion. As a result, instances of unnecessary fasciotomy and unrecognized CS are relatively common. Recently, near-infrared spectroscopy (NIRS)-based systems for compartment monitoring have generated interest as an adjunct tool. Read More

Thoracic, Peripheral, and Cerebral Volume, Circulatory and Pressure Responses To PEEP During Simulated Hemorrhage in a Pig Model: a Case Study.

J Electr Bioimpedance 2021 Jan 27;12(1):103-116. Epub 2021 Dec 27.

Walter Reed Army Institute of Research, Silver Spring, MD, USA.

Positive end-expiratory pressure (PEEP) is a respiratory/ventilation procedure that is used to maintain or improve breathing in clinical and experimental cases that exhibit impaired lung function. Body fluid shift movement is not monitored during PEEP application in intensive care units (ICU), which would be interesting specifically in hypotensive patients. Brain injured and hypotensive patients are known to have compromised cerebral blood flow (CBF) autoregulation (AR) but currently, there is no non-invasive way to assess the risk of implementing a hypotensive resuscitation strategy and PEEP use in these patients.

Pathophysiology of intraabdominal hypertension and abdominal compartment syndrome and relevance to veterinary critical care.

J Vet Emerg Crit Care (San Antonio) 2022 Jan;32(S1):48-56

Department of Veterinary Clinical Sciences, The Ohio State University, Columbus, Ohio, USA.

Background: Increased intraabdominal pressure, termed intraabdominal hypertension (IAH), is reported as an independent cause of morbidity and mortality in the human ICU but, until recently, has been rarely described in veterinary species outside of experimental models. Failure to identify severe IAH leads to organ dysfunction, termed abdominal compartment syndrome, and rapidly becomes fatal without therapeutic intervention. Although the veterinary community has been slow to address the concept of IAH and associated comorbidities, recent companion and large animal case series and experimental studies suggest IAH may also be common in veterinary species and correlates well with risk factors and grading systems already described in the human literature.

Ideal alveolar gas defined by modal gas exchange in ventilation-perfusion distributions.

Philip J Peyton

J Appl Physiol (1985) 2021 12 21;131(6):1831-1838. Epub 2021 Oct 21.

Professorial Fellow, Department of Critical Care, Melbourne Medical School, Faculty of Medicine Dentistry and Health Sciences, University of Melbourne, Melbourne, Victoria, Australia.

Under the three-compartment model of ventilation-perfusion ([Formula: see text]) scatter, Bohr-Enghoff calculation of alveolar deadspace fraction (VDA/VA) uses arterial CO partial pressure measurement as an approximation of "ideal" alveolar CO ( [Formula: see text]). However, this simplistic model suffers from several inconsistencies. Modeling of realistic physiological distributions of [Formula: see text] and [Formula: see text] instead suggests an alternative concept of "ideal" alveolar gas at the [Formula: see text] ratio where uptake or elimination rate of a gas is maximal.

Non-Invasive Intra-Abdominal Pressure Measurement by Means of Transient Radar Method: In Vitro Validation of a Novel Radar-Based Sensor.

Sensors (Basel) 2021 Sep 7;21(18). Epub 2021 Sep 7.

Department of Electronics and Informatics, Vrije Universiteit Brussel, 1050 Brussels, Belgium.

Intra-abdominal hypertension, defined as an intra-abdominal pressure (IAP) equal to or above 12 mmHg is one of the major risk-factors for increased morbidity (organ failure) and mortality in critically ill patients. Therefore, IAP monitoring is highly recommended in intensive care unit (ICU) patients to predict development of abdominal compartment syndrome and to provide a better care for patients hospitalized in the ICU. The IAP measurement through the bladder is the actual reference standard advocated by the abdominal compartment society; however, this measurement technique is cumbersome, non-continuous, and carries a potential risk for urinary tract infections and urethral injury.
