A clinical comparison of continuous interscalene brachial plexus block with different basal infusion rates of 0.2% ropivacaine for shoulder surgery
Hypotensive and bradycardic episodes in the sitting position during shoulder arthroscopy using interscalene block: can those be alerted?
Ischiorectal Block with Bupivacaine for Post Hemorrhoidectomy Pain
Background: Hemorrhoid is one of the most common surgical diseases occurring in the anorectal region. In this study, we evaluated the effect of ischiorectal fossa block on alleviating post hemorrhoidectomy pain. Methods: In this study, 90 patients suffering from hemorrhoids were evaluated. They were randomly divided into 3 groups. The first group had no block, the second group an ischiorectal block with placebo (normal saline), and the third group a preemptive ischiorectal block with bupivacaine. Postoperative variables such as pain intensity, pethidine consumption, nausea, and vomiting were compared between the groups. Results: The postoperative pain score in group 1 was 8.5 ± 1.3 and 8.1 ± 0.9 (P = NS) in group 2. The post operative analgesic demand was 3.1 ± 1.5 and 3.3 ± 1.8 hours in groups 1 and 2, respectively (P = NS). The post operative pain score and analgesic demand were 4.2 ± 2.1 and 9.3 ± 2.7 hours, respectively, in group 3 (P < 0.0001). Conclusions: Preemptive ischiorectal block reduces the posthemorrhoidectomy pain and opioid demand. © The Korean Pain Society, 2012
Reduction of the incidence of development of venous thromboembolism by ultrasound-guided femoral nerve block in total knee arthroplasty
Le blocage peropératoire “3 en 1” du nerf fémoral par une dose unique de ropivacaïne à 0,25 % ou à 0,5 % ou de bupivacaïne à 0,25 % produit une analgésie de 48 h comparable après la mise en place d’une prothèse totale de genou
Effect of continuous psoas compartment block and intravenous patient controlled analgesia on postoperative pain control after total knee arthroplasty
Extracellular matrix hydrogels from decellularized tissues: structure and function
Extracellular matrix (ECM) bioscaffolds prepared from decellularized tissues have been used to facilitate constructive and functional tissue remodeling in a variety of clinical applications. The discovery that these ECM materials could be solubilized and subsequently manipulated to form hydrogels expanded their potential in vitro and in vivo utility; i.e. as culture substrates comparable to collagen or Matrigel, and as injectable materials that fill irregularly-shaped defects. The mechanisms by which ECM hydrogels direct cell behavior and influence remodeling outcomes are only partially understood, but likely include structural and biological signals retained from the native source tissue. The present review describes the utility, formation, and physical and biological characterization of ECM hydrogels. Two examples of clinical application are presented to demonstrate in vivo utility of ECM hydrogels in different organ systems. Finally, new research directions and clinical translation of ECM hydrogels are discusse
