Filter by:A randomised controlled trial to assess the impact of femoral artery block on the incidence of tourniquet hypertension in patients receiving cruciate ligament surgery with > 30 minutes of tourniquet under combined anaesthesia (balanced general anaesthesia and femoral nerve blocks).
Various strategies have been proposed to prevent or mitigate the effects of ischemia-reperfusion injury following the use of tourniquets in orthopedic surgery cases. One of them is applying "remote ischemic preconditioning." This randomized controlled trial is planned to evaluate the effectiveness of remote ischemic preconditioning in preventing tourniquet-induced ischemia-reperfusion injury in total knee arthroscopy with dynamic thiol-disulfide homeostasis.
This study analize the incidence of acute renal failure after performing total knee arthroplasty with or without use of tourniquet limb cuff (half of patients for each group) in a randomized clinical trial
This is a randomized controlled trial designed to research the effects of different tourniquet applications on postoperative pain in patients undergoing total knee arthroplasty, and to guide early postoperative recovery.
Tourniquet is widely used in orthopedic surgery. However, prolonged tourniquet inflation may cause a gradual rise in blood pressure, which named as tourniquet-associated hypertension. Thus, to effectively prevent the tourniquet related hemodynamic responses is important for patients receiving limb surgery. Tracleer is an endothelin receptor antagonist indicated for the treatment of pulmonary arterial hypertension. Tracleer can also be used to treat retistant hypertension. At present trial, the investigators are going to investigate the effect of Tracleer on tourniquet-associated hypertension during total knee arthroplasty.
This proposed novel randomized control trial (RCT) seeks to address this gap in TKA protocol by gaining a better understanding of the relationship between tourniquet pressure and time, and intraoperative performance and post-operative outcomes. This study does not seek to answer the question of "tourniquet vs no tourniquet", but to seek a tourniquet usage that would maximize the intraoperative benefits for the surgeon and minimize the negative consequences for patient outcomes. Specific Aim #1: enroll around 146 primary TKA patients. Specific Aim #2: evaluate different tourniquet cuff pressures (TCP) and tourniquet times in relation to intraoperative performance. Specific Aim #3: evaluate different TCP and tourniquet times in relation to post-operative pain and complications of short-term, intermediate, and long-term followup. Specific Aim #4: evaluate different TCP and tourniquet times in relation to post-operative function of short-term, intermediate, and long-term followup.
There is obviously a lack of evidence regarding the risk-benefit ratio of a thigh tourniquet in unicondylar knee arthroplasty (UKA). This refers to many possible outcome criteria like operating time, blood loss, quality of prosthesis fixation in the bone, adverse events, radiographic result, clinical score outcome, easy of rehabilitation etc. It is not appropriate to rely on findings from the field of total knee arthroplasty. It is the aim of the current study, to clarify the role of a thigh tourniquet during UKA with regard to component fixation quality, component positioning and sizing, clinical outcome and rehabilitation process. Patients scheduled for routine UKA implantation due to osteoarthritis or osteonecrosis in the medial compartment will be considered for participation. Patients are then randomized for surgery with or without tourniquet. After an anteromedial Quad-Sparing approach the UKA procedure itself is then carried out, as suggested by the manufacturer. For both groups puls lavage and meticulous drying is applied before cementing. The following outcome parameters are assessed: 1)radiographic cement mantle thickness, 2)component position & sizing, 3)diolucencies, 4)score outcome and 5)parameters of early Rehab.
