Thrombocytopenic purpura would complicate surgery most likely by causing what?

Thrombocytopenic purpura is characterized by a low platelet count, which significantly increases the risk of bleeding during surgical procedures. The condition leads to a reduced ability of the blood to clot effectively, which is crucial in managing any incisions made or traumatic injuries sustained during surgery. Therefore, the primary complication that arises during surgery in patients with thrombocytopenic purpura is hemorrhage. This can manifest as excessive bleeding either at the surgical site or more generally throughout the body, potentially leading to serious complications such as shock or the need for blood transfusions.

The other options, while they may be concerns in different contexts, do not directly relate to the primary complication associated with thrombocytopenic purpura. Oedema relates more to fluid retention or inflammation but does not directly stem from a low platelet count. Acute infection is a risk associated with any surgery but not specifically linked to thrombocytopenic purpura. Nerve damage could occur in surgical contexts, but again, it is not a direct effect of having thrombocytopenic purpura.
