[Heart arrest in cemented hip arthroplasty].

Hip arthroplasty is a common surgical intervention in our hospital practice, involving high perioperative risk related to patients age and multiple concomitant diseases. Hemodynamic complications described vary from slight hypotension during surgery to heart failure and sudden death, particularly if the operation involves a cemented femoral component. Because of the type of patients undergoing such operations (elderly patients, with osteoporosis and scarce cardiopulmonary reserve), the unclear origin of complications and the lack of consensus on what constitutes adequate monitoring during surgery, hip arthroplasty is problematic for the specialists involved. We report on five deaths during cemented hip arthroplasty; after reviewing the case history and autopsy report of one, we believe the events leading to death were triggered by massive pulmonary embolism.

[After your heart arrest, would you like to test a medicinal elixir?].

So far, cardiac arrest is still associated with high mortality or severe neurological disability in survivors. At the tissue level, cardiac arrest results into an acute condition of generalized hypoxia. A better understanding of the pathophysiology of ischemia-reperfusion and of the inflammatory response that develops after cardiac arrest could help to design novel therapeutic strategies in the future. It seems unlikely that a single drug, acting as a < >, might be able to improve survival or neurological prognosis. Lessons learned from pathophysiological mechanisms rather indicate that combined therapies, involving thrombolysis, neuroprotective agents, antioxidants and anti-inflammatory molecules, together with temperature cooling, might represent helpful strategies to improve patient's outcome after cardiac arrest.
