Brief Summary

Total joint arthroplasty is one of the best treatment options for end-stage osteoarthritis. Cemented hip arthroplasty is mainly indicated for elderly patients with poor bone quality and multiple comorbidities. Bone cement implantation syndrome is associated with cemented hip arthroplasty and it has been shown to increase cardiovascular and renal complication and brain damage postoperatively. The aim of this project is to elucidate whether remote-ischemic preconditioning (RIPC) has multi-organ protective effect in cemented hip arthroplasty patients.

Detailed Description

Total joint arthroplasty is one of the best treatment options for end-stage osteoarthritis. Cemented hip arthroplasty is mainly indicated for elderly patients with poor bone quality and multiple comorbidities. Cemented hip arthroplasty is strongly associated with bone cement implantation syndrome (BCIS). It is characterized by hypoxia, hypotension and/or unexpected loss of consciousness occurring around the time of cementation, prosthesis insertion or reduction of the joint. It has been shown to increase cardiovascular and renal complication and brain damage postoperatively. Remote-ischemic preconditioning has shown kidney, myocardial and brain injury protective effect on non-cardiac surgery patients. The aim of this project is to elucidate whether remote-ischemic preconditioning (RIPC) has multi-organ protective effect in cemented hip arthroplasty patients.

GroupInterventionDescription
Control groupSHAMSHAM procedure is done one hour before cemented hip arthroplasty and comprises of 4 cycles of 5min sham procedure. Everything apart from the pressure in the cuff is similar to the RIPC procedure.
Remote Ischemic preconditioning groupRemote Ischemic PreconditioningRIPC procedure is done one hour before cemented hip arthroplasty and comprises of 4 ischemia (using brachial cuff with suprasystolic blood pressure for 5 min) and reperfusion (5 min) cycles.
