The America Society of Anesthesiology guidelines recommend multimodal analgesia that combines regional anesthetic techniques with pharmacotherapy to improve peri-procedural pain management and reduce opioid related complications. Commonly performed emergency procedures of the upper extremity such as fracture and dislocation reduction, wound debridement, and abscess incision and drainage are ideal candidates for ultrasound-guided (USG) regional anesthesia of the brachial plexus. However, adoption of regional anesthesia by emergency practitioners has been limited by concerns for potential complications and perceived technical difficulty...

A protocol based on ultrafast ultrasound imaging was applied to study the in situ motion of the liver while the abdomen was subjected to compressive loading at 3 m/s by a hemispherical impactor or a seatbelt. The loading was applied to various locations between the lower abdomen and the mid thorax while feature points inside the liver were followed on the ultrasound movie (2000 frames per second). Based on tests performed on five post mortem human surrogates (including four tested in the current study), trends were found between the loading location and feature point trajectory parameters such as the initial angle of motion or the peak displacement in the direction of impact...

PURPOSE: To investigate the relationship between the thorax diameter and defect diameter of giant omphaloceles as a predictor for fetal outcome. METHODS: In a retrospective study, 17 fetuses with isolated giant omphaloceles were included for evaluation. The anterior-posterior thorax diameter and the defect diameter were measured from ultrasound images. For analysis, the thorax-to-head ratio (T/HC), the defect diameter-to-head ratio (DD/HC), and the quotient of the defect diameter and the thorax diameter (DD/T) were calculated...

Endobronchial ultrasound (EBUS) is a technique for the detection of mediastinal abnormalities. A total of 548 EBUS procedures were performed for various indications, and in four cases (0.7%), filling defects in central pulmonary arteries were demonstrated fortuitously during the procedure. Subsequently, all patients underwent contrast-enhanced CT of the thorax to confirm the diagnosis of pulmonary thromboembolism (PTE). In three of the four cases, there was a concomitant lung cancer. PTE can be incidentally detected during EBUS; therefore, pulmonary arteries should be examined carefully during EBUS in all patients, particularly in patients with suspected or proven malignancy...

Ultrasound is increasingly being used in examination of the thorax. The sonographic features of normal aerated lung, abnormal lung, pneumothorax, and intrapleural fluid have been published. The sonographic features of uncommon intrathoracic syndromes are less known. Hydropneumothorax is an uncommon process in which the thoracic cavity contains both intrapleural air and water. Few published examples of the sonographic findings in hydropneumothorax exist. We present 3 illustrative cases of the sonographic features of hydropneumothorax with comparative imaging and a literature review of the topic...

STUDY OBJECTIVE: Historically, the placement of internal jugular central venous lines has been accomplished by using external landmarks to help identify target-rich locations in order to steer clear of dangerous structures. This paradigm is largely being displaced, as ultrasound has become routine practice, raising new considerations regarding target locations and risk mitigation. Most human anatomy texts depict the internal jugular vein as a straight columnar structure that exits the cranial vault the same size that it enters the thoracic cavity...

BACKGROUND: Acute deterioration in respiratory status commonly occurs in patients who cannot be transported for imaging studies, particularly during surgical procedures and in critical care settings. Transthoracic lung ultrasonography has been developed to allow rapid diagnosis of respiratory conditions at the bedside. Nevertheless, the thorax is not always accessible, especially in the perioperative setting. Transesophageal lung ultrasonography (TELU) can be used to circumvent this problem...

OBJECTIVE: Ultrasound (US) has been shown to be effective at identifying a pneumothorax (PTX); however, the additional value of adding multiple views has not been studied. Single- and four-view protocols have both been described in the literature. The objective of this study was to compare the diagnostic accuracy of single-view versus four-view lung US to detect clinically significant PTX in trauma patients. METHODS: This was a randomized, prospective trial on trauma patients...

Renal cell carcinomas (RCCs) have a strong tendency to metastasize, and the most common sites are the lungs, bones and liver. Late recurrence is another feature of the RCC, with lesions appearing ≥10 years after surgical treatment. However, fibrosis has rarely been associated with the disease. The present study reports a case of recurrent RCC that manifested as a fibrotic mass within the thorax. A 48-year-old man presented with dyspnea that had persisted for 3 days. The patient had undergone a right radical nephrectomy for stage II clear cell carcinoma of the kidney 6 years previously...

PURPOSE: A fetus with skeletal disorder poses diagnostic challenges in a resource-poor setting with limited management options. The objective of the study was to develop a step-by-step approach for the diagnosis of skeletal dysplasia in light of the limited resources available. METHODS: An algorithmic approach was used. The assessment for lethality was the first step, followed by the evaluation for fractures. In cases without evidence of fracture, severe constriction of thorax or associated polydactyly were searched for...

INTRODUCTION: Pneumothorax is a most rare intraoperative event but jeopardise safety. Risk factors for its occurrence should be acknowledged and it should be considered in cases of unexpected deterioration of oxygenation that not respond to standard management to improve oxygenation. PRESENTATION OF CASE: We describe a patient with mild obesity and recent shoulder trauma scheduled for elective arthroscopy under combined interscalene block and general anaesthesia in the beach chair position...
