Continuous intra-gastral monitoring of intra-abdominal pressure in critically ill children: a validation study.

Intensive Care Med Exp 2021 May 24;9(1):24. Epub 2021 May 24.

Department of Paediatric Cardiology and Intensive Care Medicine, Hannover Medical School, Hannover, Germany.

Background: In critically ill children, detection of intra-abdominal hypertension (IAH > 10 mmHg) and abdominal compartment syndrome (ACS = IAH + organ dysfunction) is paramount and usually monitored through intra-vesical pressures (IVP) as current standard. IVP, however, carries important disadvantages, being time-consuming, discontinuous, with infection risk through observer-dependent manipulation, and ill-defined for catheter sizes. Therefore, we sought to validate air-capsule-based measurement of intra-gastric pressure (ACM-IGP). Read More

Bedside monitoring of lung volume available for gas exchange.

Intensive Care Med Exp 2021 Jan 11;9(1). Epub 2021 Jan 11.

Nuffield Division of Anaesthetics, University of Oxford, Oxford, UK.

Background: Bedside measurement of lung volume may provide guidance in the personalised setting of respiratory support, especially in patients with the acute respiratory distress syndrome at risk of ventilator-induced lung injury. We propose here a novel operator-independent technique, enabled by a fibre optic oxygen sensor, to quantify the lung volume available for gas exchange. We hypothesised that the continuous measurement of arterial partial pressure of oxygen (PaO) decline during a breath-holding manoeuvre could be used to estimate lung volume in a single-compartment physiological model of the respiratory system.

The Role of Magnetic Resonance in the Diagnosis of Chronic Exertional Compartment Syndrome.

Rev Bras Ortop (Sao Paulo) 2020 Dec 2;55(6):673-680. Epub 2020 Apr 2.

Serviço de Radiologia do sistema Musculoesquelético, Fleury Medicina & Saúde, São Paulo, SP, Brasil.

Chronic compartment syndrome is a common and often underdiagnosed exercise-induced condition, accounting on average for a quarter of cases of chronic exertional pain in the leg, second only to the fracture/tibial stress syndrome spectrum. It traditionally occurs in young runner athletes, although more recent studies have demonstrated a considerable prevalence in low-performance practitioners of physical activity, even in middle-aged or elderly patients. The list of differential diagnoses is extensive, and sometimes it is difficult to distinguish them only by the clinical data, and subsidiary examinations are required. Read More
