Our anesthesia consent form (PP in OK) has sections for general, neuraxial, peripheral regional, MAC, and IV regional (we do a lot of Bier blocks). Each section has subsections for expected result, technique and possible complications.
In residency (in OH) we had no paper anesthesia consent - we only used the checkbox for "sedation" on the surgical consent. This left a lot to be desired, particularly for more complex techniques (e.g., block + GA)
