Does fasting become invalidated by receiving an anesthetic via injection for two non-surgical procedures during Ramadan?

Intramuscular and intravenous injections do not invalidate the fast of a fasting person unless they are nutritive. If they are nutritive, then they fall under the ruling of eating and drinking. It is preferable to take them at night if possible. Likewise, local or general anesthesia does not invalidate the fast. If a person who lost consciousness regains it, even for a moment during the day, their fast is valid as long as they had intended to fast from the night.
