Filter by:This study has been designed to assess the possible advantages of using ultrasound imaging to block the brachial plexus (i.e., nerves of the upper limb) in patients undergoing shoulder surgery. The ultrasound technique will be compared with the current gold standard, electrical nerve stimulation. The aim of this study is to define which technique is better in terms of time to onset of anesthesia.
To determine whether a single dose of intravenous lornoxicam is superior to intravenous placebo for management of post-operative pain in patients who have surgical removal of a bunion on the lower extremity. One-fourth of patients in this study will receive a single dose of intravenous ketorolac for management of pain and one-fourth of patients in this study will receive a single dose of an intravenous placebo.
The purpose of this study is to determine whether epoetin alfa will enable self-donation of at least 4 units of blood during the 2-week period before surgery (which is a shorter period of time than the conventional 3-week blood donation period before surgery) in patients who are not anemic and who will be undergoing orthopedic or heart and blood vessel surgery. Epoetin alfa is a genetically engineered protein that stimulates red blood cell production.
The purpose of this study is to determine the safety and effectiveness of epoetin alfa and whether epoetin alfa will enable self-donation of blood during an 11-day period before surgery (which is shorter than the conventional 3-week blood donation period before surgery) in patients who are not anemic and who will be undergoing orthopedic, heart and blood vessel, or breast reduction surgery. Epoetin alfa is a genetically engineered protein that stimulates red blood cell production. Normovolemic hemodilution (NVHD, withdrawal of a patient's blood immediately before surgery, immediate replacement of blood with an equal volume of fluid, and return of the withdrawn blood after completion of surgery; a procedure which reduces the loss of blood during surgery) will also be performed.
The purpose of this study was to evaluate the changes in heart function during onset of spinal anesthesia using a new and less invasive method, the LidcoTMplus.
