Effects of Medications on Post-Endoscopic Retrograde Cholangiopancreatography Pancreatitis

“…It has been widely used during endoscopic procedures on patients of all ages due to its rapid onset of sedation and recovery from sedation. Over the past decade, a number of cases were reported about the causational relationship of propofol use with acute pancreatitis [2,3,4]. In one case, propofol appeared to be the only identified cause of acute pancreatitis in a young child after short-term use of the drug without other risk factors [3].…”

“…Over the past decade, a number of cases were reported about the causational relationship of propofol use with acute pancreatitis [2,3,4]. In one case, propofol appeared to be the only identified cause of acute pancreatitis in a young child after short-term use of the drug without other risk factors [3]. Another case was reported of pancreatitis on a propofol drip and recurred following an inadvertent re-challenge with propofol [4].…”

“…Propofol therefore has become a favorable sedative drug for many gastrointestinal procedures. In recent years, several articles have reported the possible association between propofol and acute pancreatitis [2,3,4]. Since the risk of developing post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis is up to 15.1% [5], reports of propofol-related pancreatitis raise additional concern for physicians attempting to minimize risk to their patients.…”

Short‐time fabrication of well‐mixed high‐density polyethylene/ultrahigh‐molecular‐weight polyethylene blends under elongational flow: morphology, mechanical properties and mechanism

“…The raised T o and T m might be attributed to the increase in molecular weight. 27,[44][45][46] The decrease of c might be attributed to that UHMWPE crystallizes to a much smaller extent than HDPE, and the UHMWPE long chains are more difficult to move than HDPE short chains, 12 indicating the existence of UHMWPE long molecular chains in crystals corresponding to the increase in molecular weight. 43,47,48 Meanwhile, there is no shoulder peak in the initial crystallization process shown within the dashed circle line in Fig.…”

“…There were also some small grapelike swellings in the fibrils, some of which may be ascribed to the point of fracture. 46,58 Importantly, the flat area, paraboloid structure and elongated fibril zone arranged in turn along the fracture direction, implying the tendency to increasing difficulty of fracture.…”
