Objective: An optical imaging system is proposed for quantitatively assessing jugular venous response to altered central pressure. Methods: The assesses sub-surface absorption changes from waveforms with a spatial calibration procedure normalize incident tissue illumination. Widefield frames of the right lateral neck were captured and calibrated using novel flexible surface method. A hemodynami...

OBJECTIVE To investigate the effectiveness and safety of controlled venous pressure in liver surgery and further to compare the clinical outcomes of low central venous pressure by infrahepatic inferior vena cava clamping (IVCC) and intraoperative anesthetic control (IAC). METHODS Online databases including PubMed, Embase, Cochrane Library, Clinical trials.gov, and China biology medicine datab...

Traditional recommendations suggest placement of a subclavian central venous catheter (CVC) ipsilateral to a known pneumothorax to minimize risk of bilateral pneumothorax. We present the case of a 65-year-old male with a right hemopneumothorax who was found to have intrathoracic placement of his right subclavian CVC at thoracotomy despite successful aspiration of blood and transduction of centr...
