Hyperspectral evaluation of skin blood oxygen saturation at baseline and during arterial occlusion

2018

Skin capillary blood oxygen saturation is a clinically important diagnostic parameter, which provides valuable information for timely treatment of pathological conditions e.g. sepsis, hypoxemia or decompression illness. Hyperspectral imaging is non-invasive optical techniques with high clinical potential, however its use for skin blood oxygen saturation detection is still challenging, therefore in the present study, a method for in-vivo manipulation of skin oxygen saturation was developed, and reliability of the method evaluated by means of hyperspectral imaging in detection of oxygen saturation. In order to produce alterations of skin capillary blood parameters and oxygen saturation, the p…

Anestesisykepleieres metoder for å kontrollere cufftrykk – en observasjonsstudie

2021

Bakgrunn: Forskning viser at pasienter i generell anestesi som har fått sine luftveier sikret med en larynxmaske eller en endotrakealtube opplever postoperative pharyngolaryngeale komplikasjoner. Et kontrollert cufftrykk har vist reduksjon i komplikasjoner.
 Hensikt: Hensikten med studien var å undersøke hvilke metoder anestesisykepleiere bruker for å kontrollere cufftrykk, og hvilke begrunnelser de har for å bruke cufftrykkmanometer.
 Metode: Totalt 45 anestesisykepleiere ble observert når de kontrollerte cufftrykket i en endotrakealtube og en larynxmaske. Anestesisykepleierne ble i tillegg spurt om hvilke begrunnelser de hadde for å bruke eller ikke bruke cufftrykkmanometer.&#x0…

Association of Arthroscopically-Assisted Latissimus Dorsi Tendon Transfer with Implantation of a Subacromial Balloon Spacer for Patients with Irrepar…

2022

Purpose. Massive irreparable posterosuperior rotator cuff tears in an active population, resulting in a pseudo-paralytic shoulder, pose a challenge for the orthopaedic surgeon. In an effort to avoid or delay arthroplasty surgery, other surgical strategies such as arthroscopically-assisted latissimus dorsi transfer (aLDT) or the implantation of a subacromial spacer (SAS) can be considered. The aim of the present study is to associate, for the first time, these two surgical procedures in order to demonstrate the surgical feasibility and the effectiveness of their synergistic biomechanical effect. Methods. The study group consisted of patients who underwent aLDT for a massive irreparable poste…

Ultrasound-guided musculoskeletal interventional procedures around the shoulder

2021

Ultrasound is a fast, accessible, reliable, and radiation-free imaging modality routinely used to assess the soft tissues around the shoulder. It enables to identify a wide range of pathological conditions. Furthermore, most ultrasound-guided musculoskeletal interventional procedures around the shoulder produce better results in terms of accuracy and clinical efficacy than those performed in a blinded fashion. Indeed, intra-articular and peri-articular interventional procedures can be easily performed under continuous ultrasound monitoring to ensure the correct position of the needle and to deliver the medication to a specific target. Several technical approaches and medications can be used…

Niederfeld MR-Arthrographie der Schulter: Erste Ergebnisse mit einem offenen 0,2 T MR-System

1998

PURPOSE To assess the practicability and image quality of doing MR arthrography of the shoulder using a 0.2T system. PATIENTS AND METHOD 60 patients (24 with chronic instability, 36 with impingement syndrome) were examined in an open 0.2T MR apparatus (Magnetom Open, Siemens). After the intra-articular injections of 15-20 ml of a 2 mmol Gd-DTPA solution, coronary STIR, T1-weighted, sagittal and axial T2*-weighted FLASH 2D sequences were performed. 21 patients subsequently underwent surgery. RESULTS Image quality of the T1- and T2*-weighted FLASH 2D sequences was regarded as good or adequate and movement artifacts were minor or moderate. STIR sequences were statistically significantly worse …

Correlation of skeletal muscle blood oxygenation level-dependent MRI and skin laser doppler flowmetry in patients with systemic sclerosis

2013

Purpose To investigate the origin of skeletal muscle BOLD MRI alterations in patients with systemic sclerosis (SSc) by correlating BOLD MRI T2* signal of calf muscles with microcirculatory blood flow of calf skin measured by laser Doppler flowmetry (LDF). Materials and Methods BOLD MRI (3T) and LDF measurements were performed in 12 consecutive SSc patients (6 women, 6 men; mean age 54.0 ± 10.0 years) and 12 healthy volunteers (4 men, 8 women; mean age 44.7 ± 13.1 years). For both modalities, the same cuff compression paradigm at mid-thigh level was used. LDF datasets were acquired using a PeriScan PIM II Imager (Perimed AB, Stockholm, Sweden) at the upper calf corresponding to the level of …

Reliability of isokinetic assessment of shoulder-rotator strength: a systematic review of the effect of position.

2011

Context:Isokinetic assessment of shoulder internal- (IR) and external-rotator (ER) strength is commonly used with many different postures (sitting, standing, or supine) and shoulder positions (frontal or scapular plane with 45° or 90° of abduction).Objective:To conduct a systematic review to determine the influence of position on the intersession reliability of the assessment of IR and ER isokinetic strength, to identify the most reliable position, and to determine which isokinetic variable appears to be most stable in intersession reliability.Evidence Acquisition:A systematic literature search through MEDLINE and Pascal Biomed databases was performed in October 2009. Criteria for inclusion…

Internal Fixation of Proximal Humeral Fractures: Current Concepts

2003

Fractures of the proximal humerus are an increasingly common type of injury. Mainly elderly patients with osteoporotic bone are affected. Whereas non-displaced and stable fractures are managed successfully with conservative treatment, there is no general agreement on the surgical strategy for displaced and unstable two- to four-part fractures. The clinical outcome is influenced by the fracture type and concomitant injury to the rotator cuff. Extensive surgical manipulation of the soft tissues, non-anatomic and/or unstable fixation as well as technical errors are important contributing factors to poor clinical results. Goals of surgical treatment are to restore anatomy, to achieve fixation t…
