Filter by:Obesity is associated with poor surgical outcome and complications. The literature does not provide a comprehensive view on the effect of body mass index (BMI) on perioperative outcomes in orthopedic surgeries. Therefore, we aim to determine the effect of BMI on 30-day perioperative outcomes in patients undergoing the first 25 most commonly performed orthopedic surgeries using a retrospective cohort study design. The knowledge of the effect of BMI on orthopedic surgeries will improve the knowledge of surgeons about the expected morbidities.
The objective of this study is to compare the incidence of postoperative urinary retention related to spinal anesthesia with morphine and spinal anesthesia associated with peripheral blockade in orthopedic procedures of lower limbs. Secondary objectives are assessing the incidence of nausea and vomiting; postoperative pain and opioid consumption at 24 hours after surgery with each of the techniques. A total of 52 patients submitted to a lower limb orthopedic procedure were randomized to the intervention groups: spinal anesthesia with morphine versus spinal anesthesia without opioid associated with peripheral nerve block. After surgery, bladder ultrasound will be performed in post-anesthesia care unit to identify urinary retention and patients will be followed for 24 hours to assess outcomes.
using a biased-coin design up-down sequential method, different concentration of lidocaine will be used for popliteal block After 45 successful block (positive response), the data will be used to calculate the minimum lidocaine concentration that can result in successful popliteal block in 90% of patients
Patients undergoing semi-elective lower extremity major amputation from complications associated with atherosclerotic limb ischemia will received intra-muscular injections of allogeneic Mesenchymal Stromal Cells in the leg above and below the point of amputation to prevent ischemic wound complications after surgery and decrease the incidence of revision and further amputation. Cohort Groups 1-4 will serve as controls.
The investigators anticipate that utilization of retapamulin preoperatively will eliminate MRSA colonization among patients who are colonized in their nares.
The purpose of this small study was to investigate the safety and effectiveness of OROS hydromorphone HCI for the treatment of short-term, moderate to severe postoperative pain following total knee replacement surgery.
The purpose of this study is to evaluate the safety and effectiveness of epoetin alfa at doses of 150, 300, or 600 units per kilogram of body weight versus placebo in facilitating presurgical collection of blood for self-donation during surgery of the knee, hip or spine. Epoetin alfa is a genetically engineered protein that stimulates red blood cell production.
The purpose of this study is to evaluate the safety and effectiveness of epoetin alfa and to determine whether epoetin alfa will facilitate self-donation of blood before surgery in patients who have anemia, (as indicated by low hematocrit levels, the percent of red blood cells in whole blood) and who will be undergoing orthopedic surgery. Epoetin alfa is a genetically engineered protein that stimulates red blood cell production.
The purpose of this study is to evaluate the safety of epoetin alfa and to determine whether epoetin alfa will reduce the need for blood transfusions during the period of time around major orthopedic surgery. Epoetin alfa is a genetically engineered protein that stimulates red blood cell production.
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.
