NCT ID: NCT01622647 Completed - Clinical trials for Knee Replacement Surgery

The Effect of Nasal Continuous Positive Airway Pressure (N-CPAP) on Arterial pCO2 During Spinal Anesthesia

Start date: July 2012
Phase: N/A
Study type: Interventional

The proposed study intends to investigate several aspects of the respiratory effects of intravenous sedation of patients undergoing spinal anesthesia for knee replacement surgery. The study will include assessment of PaCO2 during the intraoperative period. PaCO2 is expected to be elevated as a result of intravenous sedation and postural factors. Further, the study will investigate how application of Nasal Continuous Positive Airway Pressure (N-CPAP) may impact PaCO2.

NCT ID: NCT01410240 Completed - Osteoarthritis Clinical Trials

Efficacy and Safety of FLOSEAL for Hemostasis in Total Knee Arthroplasty

Start date: September 2011
Phase: Phase 4
Study type: Interventional

The purpose of this study is to compare the efficacy and safety of FLOSEAL to standard of care for hemostasis in subjects undergoing total knee arthroplasty.

NCT ID: NCT01375231 Completed - Clinical trials for Knee Replacement Surgery

Anatomic Reconstruction of the Patellofemoral Joint

Start date: June 2011
Phase: Phase 4
Study type: Interventional

The investigators posit that it would be advantageous to reproduce the height of the entire patellofemoral joint in order to maintain the lever arm of the quadriceps mechanism at its preoperative level. Failure to do this may cause the quadriceps mechanism to be inefficient. For example the quadriceps mechanism would have to work harder if the total patellofemoral (PF) height is diminished. Alternatively, diminished motion or increased patellar strain may occur if the overall PF height is increased. The investigators theorize that either of these sizing errors could lead to anterior knee pain. The purpose of this study is to compare the clinical outcomes between two surgical techniques: 1) a technique of reproducing the total PF joint on both sides of the articulation (Group 1) and 2) the traditional technique of reproducing only the patellar thickness on one side of the joint (Group 2).

NCT ID: NCT01213602 Completed - Clinical trials for Knee Replacement Surgery

Bilateral Bispectral Index (BIS)-Monitoring in Trauma Surgery

Start date: February 2010
Phase: N/A
Study type: Observational

The principal objective is to notice the relevance of timing performance of femoral block for knee replacement surgery during general anesthesia and analyze the relationship with bilateral bispectral index (BIS) monitoring during induction and maintenance of anesthesia. Otherwise the investigators try to investigate if the timing of performance of this block influence in postoperative variables as pain or blood loss.
