You can look at the operative risks as occurring: per-operatively (before the surgery) intra-operatively (during the surgery) post-operatively (after the surgery) The highest risk to the patient is thought to be intra-operatively, or during the procedure, although there are activities before and after the operation that must be considered very risky as well. Some of these things on this list become trade-offs such as surgical drains- although they increase risk, a higher risk would be taken if there was a need for a drain it was not place. Placement of a foreignobject is part of the procedure for valve replacement of hip replacement. However there are some withing this list that are risk factors that we can mitigate or eliminate.
