CicatrisationMots-clés : Mesure transcutanée des gaz du sang Résumé : Loxymétrie cutanée ou TcPO2 correspond à la mesure de la pression transcutanée en oxygène. Elle est généralement évaluée selon la méthode polarographique de Clark reposant sur lapplication dune électrode au contact dune solution hydro-électrolytique appliquée sur la peau. La TcPO2 est le reflet indirect de la perfusion cutanée. Son évaluation représente un examen non invasif dont la réalisation pratique impose une grande rigueur, de nombreux paramètres indépendants ou non de la perfusion elle-même pouvant modifier la mesure. Ces paramètres doivent être connus pour évaluer la pertinence de lexamen et disposer de chiffres interprétables. Elle doit être réalisée par un personnel formé et qualifié. Elle est prescrite en pratique médico-chirurgicale vasculaire pour lévaluation des possibilités de cicatrisation des troubles trophiques chez les patients souffrant dune artériopathie oblitérante athéromateuse ou non, dans le cadre de lévaluation des patients au stade de lischémie de repos ou en ischémie critique, lors du bilan pré-opératoire avant amputation pour évaluer les possibilités de cicatrisation en fonction du niveau damputation et enfin pour évaluer la réserve vasculaire avant prescription dun éventuel traitement vasodilatateur par prostacycline.

To determine the utility of home-based, unsupervised transcutaneous partial pressure of carbon dioxide (tc-Pco2) monitoring/oxygen saturation by pulse oximetry (Spo2) for detecting nocturnal hypoventilation (NH) in individuals with neuromuscular disorders.
Design
Retrospective case series analyzed consecutively.
Setting
Multidisciplinary neuromuscular respiratory failure (NMRF) clinic at an academic institution.
Participants
Subjects (N=35, 68.6% men; mean age, 46.9y) with spinal cord injury (45.7%) or other neuromuscular disorders underwent overnight tests with tc-Pco2/Spo2 monitoring. Fifteen (42.9%) were using nocturnal ventilatory support, either bilevel positive airway pressure (BiPAP) or tracheostomy ventilation (TV).
Interventions
A respiratory therapist brought a calibrated tc-Pco2/Spo2 monitor to the patients home and provided instructions for data collection during the subjects normal sleep period. Forced vital capacity (FVC), body mass index (BMI), and exhaled end-tidal Pco2 (ET-Pco2) were recorded at a clinic visit before monitoring.
Main Outcome Measures
Detection of NH (tc-Pco2 ≥50mmHg for ≥5% of monitoring time). Data were also analyzed to determine whether nocturnal oxygen desaturation (Spo2 ≤88% for ≥5% of monitoring time), FVC, BMI, or daytime ET-Pco2 could predict the presence of NH.
Results
NH was detected in 18 subjects (51.4%), including 53.3% of those using BiPAP or TV. NH was detected in 43.8% of ventilator-independent subjects with normal daytime ET-Pco2 (present for 49.4%+31.5% [mean + SD] of the study period), and in 75% of subjects with an elevated daytime ET-Pco2 (present for 92.3%+8.7% of the study period). Oxygen desaturation, BMI, and FVC were poor predictors of NH. Only 3 attempted monitoring studies failed to produce acceptable results.
Conclusions
Home-based, unsupervised monitoring with tc-Pco2/Spo2 is a useful method for diagnosing NH in NMRF."Disponible en ligne : Oui En ligne : https://login.ezproxy.vinci.be/login?url=https://www.sciencedirect.com/journal/a [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=117356

Rééducation et réadaptationMots-clés : Amputation stumps Moignons d'amputation Blood Gas Monitoring Transcutaneous Mesure transcutanée des gaz du sang Spectroscopy near-infrared Spectroscopie proche infrarouge Résumé : Objective
To examine metrologic properties of near-infrared spectroscopy (NIRS) versus transcutaneous oxygen tension (TcPO2) for microcirculatory assessment of vascular transtibial stumps at the stabilized period of prosthesis fitting, as a preliminary step before exploring its ability to predict stump healing, considering the previously identified limits of TcPO2 (borderline area between 15 and 35mmHg).
Design
Prospective single-center observational study.
Setting
University-based rehabilitation center.
Participants
Individuals with unilateral transtibial amputation for peripheral artery disease, at the definitive stage of prosthesis fitting, able to perform a 2-minute walk test (N=30).
Interventions
Not applicable.
Main Outcome Measures
Test-retest, with the stump being evaluated in supine and inclined positions, first by NIRS (tissue saturation index [TSI], oxyhemoglobin, deoxyhemoglobin, and total hemoglobin) and second by TcPO2. Subjects carried out a 2-minute walk test and visual analog scales (wound healing and pain).
Results
Feasibility and tolerance of NIRS were satisfactory. The reliability of NIRS and TcPO2 values was good (intraclass correlation coefficient >0.7; P<.05 no significant relation was found between nirs and tcpo2. responsiveness vs supine reported>.05). A significant relation between TSI and the 2-minute walk test (r>.49, P<.05 was found.> Conclusions
NIRS is painless, complication-free, and feasible, with good reliability. NIRS evaluates others domain than TcPO2 that are more linked to metabolic adaptation. Its capacity to predict stump healing and tolerance to early prosthesis fitting is therefore interesting to estimate in future studies.Disponible en ligne : Oui En ligne : https://login.ezproxy.vinci.be/login?url=https://www.sciencedirect.com/science/a [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=117867
