Are doctors pro or against general anesthesia in small routine surgery?

Depends : If you are relatively healthy then yes getting anesthesia will not be a problem. If you have multiple medical problems complication rate rises then it is advisable to do with least amount of anesthetic and use local or nerve block.

Not necessary: I typically don't request general anesthesia for small procedures, because in my opinion it's overkill. However, several factors come into play when making that decision, including input from surgeon, anesthesiologist and patient.

It depends on : Many factors, including the type of surgery, the preference of the patient, patient co-morbidities, surgeon preference and anesthesiologist preference. Each case should be decided on its own merits.

See below: General=asleep, regional=numb, local=skin. Once a patient has decided upon a surgery there is not usually a great choice for the anesthetic. In the or a patient may get a regional for knee surgery, but also gets enough anesthesia to put them asleep for the operation. There only preference is how the combinations are bound together to provide the best care for the patient..
