Final answer:
The common side effects of methohexital include respiratory depression, potential allergic reactions, and postoperative nausea and vomiting. Epinephrine is used to counteract anaphylactic shock, which can be a severe allergic reaction. Prolonged emergence is not commonly associated with methohexital.
Step-by-step explanation:
Common side effects of methohexital, which is a general anesthetic, include a range of adverse effects. Some of these are respiratory depression, which is a common concern with many anesthetics due to their effect on the central nervous system, leading to impaired respiratory function. Allergic reactions, though less common, can occur and may present as anaphylaxis, which is a severe and potentially life-threatening reaction. However, one of the drugs used to counteract the effects of anaphylactic shock is epinephrine. Another side effect can be postoperative nausea and vomiting (PONV), which is often reported by patients following surgery and anesthesia. Prolonged emergence is not typically cited as a common side effect of methohexital but can occur with any anesthetic. It's important to monitor and manage these side effects to ensure patient safety and comfort.
