本題題幹為大腸癌手術為<避免併發手術部位感染>，靜脈注射抗生素使用時機為何?
主要是題意並沒有說清楚是要問預防性抗生素使用時機易誤導考生，即使是問預防性，若
是手術時間延長，
根據Sabiston Textbook of Surgery 17th(電子版) Chap.12 Surgical Infections and
Choice of Antibiotics p262
For most patients with elective surgery, the first dose of prophylactic
antibiotics should be given intravenously at the time anesthesia is induced.
It is unnecessary and may be detrimental to start them more than 1 hour
preoperatively, and it is unnecessary to give them after the patient leaves
the OR. A
single dose, depending on the drug used and length of operation, is often
sufficient. For operations that are prolonged, the prophylactic agent chosens
hould be given in repeated doses at intervals of one to two half-lives for
the drug being used.
那就必須要再給予抗生素補強；或是術中弄破腸道或腸內容物滲漏，也是可能要繼續給抗
生素。所以公佈答案(D)術前三十分鐘為預防性抗生素使用時機,但由此題看來(B)術前三十分鐘至術後三天也不算錯。

剪不斷
理還亂
是離愁 是鄉愁 是愛恨情仇
寂寞裡清秋
深夜獨上西樓
