Usono, a company based in The Netherlands, has created a new kind of ultrasound accessory that is an important diagnostic tool as well as a way to improve reproducibility of ultrasound images. ProbeFix is a fixation system for transthoracic ultrasound probes that allows doctors to effortlessly image patients’ hearts without having to strain to hold the probe in place during exams. At World of Health Care 2017 held in Holland earlier this year, visitors voted Usono the winner of the Smart Solutions Award. ProbeFix looks like a harness and is put on the patient before a cardiac ultrasound exam begins. Thanks to the des...

A LONG-AXIS (LAX) view of the trachea and larynx in a 3-yr-old girl after intubation with a cuffed endotracheal tube (4.0-mm internal diameter) (fig. A), and a short-axis (SAX) view of the trachea with a transverse tracheal width of 7.0  mm before intubation (fig. B), were obtained using an ultrasound apparatus with an L12-2 MHz probe. The cricothyroid membrane was palpated around 25  mm from the suprasternal notch etch. Hyperechoic shadows mostly indicated anterior membranes of the cricoid or tracheal cartilage. The saline-inflated cuff position was confirmed below the cricoid cartilage in the trachea. The s...

AbstractPurpose of ReviewAdequate oxygen delivery is essential for life, with hypoxia resulting in dysfunction, and ultimately death, of the cells, organs and organism. Blood flow delivers the oxygen bound in the blood, while haemodynamics is the science of blood flow. Stroke volume (SV) is the fundamental unit of blood flow, and reflects the interdependent performance of the heart, the vessels and the autonomic nervous system. However, haemodynamic management remains generally poor and predominantly guided by simple blood pressure observations alone.Recent FindingsDoppler ultrasound measures SV with unequalled clinical pr...

Authors: Kim HT, Kim SY, Byun GJ, Shin BC, Lee JY, Choi EJ, Choi JB, Hong JH, Choi SW, Kim YD Abstract Background: Recently, the use of ultrasound (US) techniques in regional anesthesia and pain medicine has increased significantly. However, the current extent of training in the use of US-guided pain management procedures in Korea remains unknown. The purpose of the present study was to assess the current state of US training provided during Korean Pain Society (KPS) pain fellowship programs through the comparative analysis between training hospitals. Methods: We conducted an anonymous survey of 51 pain physici...

Abstract BACKGROUND: Radial arterial cannulation is most commonly done using palpation, but the use of ultrasound has increased the cannulation success rate. This improvement, albeit significant, has not led to a very high success rate especially in trainees. A modified ultrasound technique for vascular cannulation (dynamic needle tip positioning) has been described for peripheral venous cannulation. We therefore assessed the success rate of this technique compared to the palpation technique for radial artery cannulation in adult surgical patients. METHODS: We enrolled patients who were having nonemergent ope...

r AR Abstract BACKGROUND: Landmark and ultrasound-guided transversus abdominis plane blocks have demonstrated an opioid-sparing effect postoperatively after cesarean delivery. The more posterior quadratus lumborum (QL) might provide superior local anesthetic spread to the thoracolumbar fascia and paravertebral space. The aim of our study was to evaluate the efficacy of the QL block after cesarean delivery. METHODS: A randomized, double-blind, controlled trial was performed. Forty parturients undergoing cesarean delivery received bilateral ultrasound-guided QL blocks with either 2 mg/mL ropivacaine or saline p...

CONCLUSION: Compared with the intravenous route, perineural dexamethasone prolongs the mean interscalene block duration by a small amount that may or may not be clinically significant, regardless of dose. However, the difference in mean block durations between 8 mg and 4 mg of dexamethasone is highly unlikely to be clinically important, regardless of the administration route.

In this study, a strategy of fractionated (multiple) treatments was tested for efficacy.MethodsDahl SS rats were anesthetized and prepared for treatment with a focused ultrasound transducer in a warm water bath. Aiming at the anterior left ventricular wall was facilitated by imaging with a 10  MHz phased array (10S, GE Vivid 7, GE Vingmed Ultrasound, Horten, Norway). MCET was accomplished at 1.5 MHz by pulse bursts of 4 MPa peak rarefactional pressure amplitude, which were intermittently triggered 1:8 from the ECG during infusion of a microbubble suspension for cavitation nucleation. Test groups were sham, a...
