Filter by:Randomized clinical trial to compare the patient's experience after peripheral venipuncture catheterization using the conventional technique (vein visualization and palpation) versus ultrasound-guided venous puncture. Patients with indication of peripheral venous puncture, admitted to the clinical inpatient units on the hospital where the study will be conducted (Hospital de Clinicas de Porto Alegre - HCPA) will be enrolled in this single-center trial and will be randomized to conventional peripheral venipuncture performed by a registered nurse; or ultrasound-guided peripheral venipuncture performed by a registered nurse with expertise in vascular access.
Randomized clinical trial to test the assertiveness on the peripheral vein puncture attempt by comparing two methods: peripheral venipuncture catheterization using the conventional technique (vein visualization and palpation) versus ultrasound-guided venous puncture. Patients with indication of peripheral venous puncture, admitted to the clinical inpatient units on the hospital where the study will be conducted (Hospital de Clinicas de Porto Alegre - HCPA) will be enrolled in this single-center trial and will be randomized to conventional peripheral venipuncture performed by a registered nurse; or ultrasound-guided peripheral venipuncture performed by a registered nurse with expertise in vascular access.
The insertion of central venous catheters (CVCs) has become an integral part of management of a critically ill patient. Access to the central vein may be required for the administration of hyper osmotic or vasoactive compounds, parenteral nutrition, and rapid infusion of large volumes of fluid or for the continuous or intermittent monitoring of biochemical or physiological parameters. Central venous catheter insertion is also indicated when the insertion of a peripheral line is not possible. Traditionally, CVC insertions have been performed using the landmark technique. Considering the number of CVCs being inserted every day, this can amount to a large number of complications. Efforts to minimize and prevent the occurrence of complications should be a routine component of quality improvement programs. There is an increasing body of evidence supporting the use of ultrasound guidance for CVC placement. This makes the strong rationale to conduct this research thus the aim of this study is to evaluate the real benefits i.e outcome of Long versus Short Axis ultrasound guided approach for internal jugular vein cannulation in the patient for elective cardiac surgery as central venous cannulation (CVC).
Quadriceps femoris (QF) atrophy is seen in rheumatoid arthritis and knee osteoarthritis (OA) patients. Exercise therapy is mile stone in knee OA patients also it can help thicken QF muscle of RA patients. We primarily aimed to demonstrate the influence of 4 weeks of knee isometric home-based training on QF muscle parts thickness and pennation angle measurements of RA patients with ultrasonography (USG). This study included 12 patients with RA, 12 patients with knee OA as positive control group and 13 volunteers as healthy control group. All participants were given 4 weeks of quadriceps-hamstring isometric home-based training. At baseline and at the end of the program, WOMAC and Lequesne algofunctional index scores of knee OA patients and DAS28-CRP scores of RA patients were recorded. Dominant knee thickness and pennation angle measurements of QF muscle parts were evaluated by ultrasonography.
Pulmonary aspiration is one of the most serious risks of general anesthesia and has been reported to occur in as many as 1 in 4000 cases of general anesthesia. Gastric ultrasound is an emerging point-of-care tool that provides bedside information on gastric content and volume. There have been a few factors which are thought to increase gastric size. Delayed gastric emptying such as caused by gastroparesis in Diabetes Mellitus is an example. Certain surgeries also cause gastroparesis. Other preoperative factors including pain, preoperative anxiety, and blood levels of estradiol or progesterone are less well studied.
Obesity is an important public health problem all over the world, and its prevalence is increasing every year. In obesity, significant changes occur in the mechanical properties of the lungs and chest wall due to fat deposits in the mediastinum and abdominal cavities. Upper abdominal surgical procedures usually cause impairment of respiratory functions by affecting respiratory volume and capacity. The risk of postoperative pulmonary complications increases with the decrease in restrictive capacities, hypoxemia, and increased respiratory work. It may also be due to causes such as diaphragm dysfunction, postoperative pain, and surgical incision.Ultrasonography (USG) is a method accepted for evaluating the normal and pathological conditions of the diaphragm. M-mode is used to evaluate the anatomical and functional disorders of the diaphragm. The diaphragm evaluation is performed with the anterior approach in the supine position and with different respiratory maneuvers (sniffing, deep inspiration, normal inspiration). The aim of the study was to evaluate the diaphragm function by using USG and spirometry methods in patients who underwent bariatric surgery and to investigate the effect of postoperative pain score on diaphragm function.
Using color Doppler ultrasound to screen people with breast masses. For the patients who show only a single mass on either side of the breast in color Doppler ultrasound, computer tomography photoacoustic breast imaging will be performed. By comparing the two modalities, the blood vessel imaging performance of the computer tomography photoacoustic breast imaging system developed by Union Photoacoustic technologies Co., Ltd is evaluated. The evaluation index of this experiment is the percentage of blood vessel pixels in the same region of interest (Region Of Interest, ROI) to the total area of the ROI.
Context: Thoracic spine is a common area of focus in osteopathic manipulative medicine (OMM) for a variety of conditions. Thoracic spine somatic dysfunction diagnosis is achieved by palpating for asymmetry at the tips of the transverse processes. Previous studies reveal that, instead of following the rule of threes, the transverse processes of a given thoracic vertebra generally align with the spinous process of the vertebra above. Ultrasonography has been widely used as a diagnostic tool to monitor musculoskeletal conditions. Ultrasound has the advantage of absence of radiation, and has shown comparable results to gold standard modalities like MRI in some areas of the spine. In the case of thoracic somatic dysfunction, ultrasound can be used to determine the location of each vertebral transverse process and its relationship with the spinous process. Previous studies have investigated the correlation between osteopathic manipulative medicine and ultrasonography of the cervical, lumbar, and sacral regions. However, no study has yet compared osteopathic structural examination with ultrasonographic examination of the thoracic vertebral region. Objective: To determine whether there is a dependable correlation of osteopathic palpatory findings of the thoracic transverse processes with the measurements of ultrasonography. Methods: Subjects were student volunteers recruited from the Midwestern University - Glendale campus. A non-toxic, non-permanent marker was used to mark bony landmarks on the skin to be used by the osteopathic examiners. Two osteopathic physicians (OMM1, OMM2) separately performed structural exams by palpating T2-T5 transverse processes to determine vertebral rotation. Two trained sonographers (US1, US2) separately scanned and measured the distance from the tip of the spinous process to the adjacent transverse processes of the vertebral segment below. Demographic variables were summarized with mean and standard deviation. Interexaminer reliability was assessed with percent agreement, Cohen's Kappa, and Fleiss' Kappa. Recruitment and protocols were approved by the MWU Institutional Review Board.
Determination of fetal head position during labour is highly subjective and depends on clinician's experience in vaginal digital examination. Monitoring the progress of labour with intrapartum ultrasound (IU) exhibits higher accuracy rates. However, the dynamic process of labour needs very frequent sonographic examination and that may decrease the feasibility. Consultation to IU at certain time points can positively limit the need for ultrasound, increase the effectiveness of IU and allow for safer labour in consistency with traditional labour management. This study aims to investigate the use of IU in cases with suspected and diagnosed labour arrest in both the first and second stage of labour.
The carpal tunnel syndrome (CTS) is a common entrapment neuropathy caused by compression of the median nerve at the wrist.Clinically electroneuphysiological assessment is not accessible to all clinicians. In this way ultrasounds (US) is a more accessible and economical tool and many studies have reported that US has high sensitivity and specificity in the diagnosis of CTS.Diacutaneous Fibrolysis (DF) is a physiotherapeutic technique derived from Cyriax deep friction massage principles.DF technique could assist in improving changes in the connective tissues adjacent to the median nerve, especially the thickness of TCL and this could be reflected in a decreasing of TCL. Moreover, the neurophysiological and mechanical effect described by this technique may improve the nerve compression decreasing the CSA of the median nerve. The purpose of this study is to quantify changes in the cross-sectional area of the median nerve in the carpal tunnel and the thickness of transversal carpal ligament measured by US and the changes in the intensity of the numbness and the subjective assessment of clinical change after DF treatment in forearm, wrist and hand area compared to placebo.
