What to anesthesiologists do?

Answer 1

In general, an anesthesiologist is a medical Doctor Who cares for a patient before, during and immediately following a surgical or medical procedure by administering appropriate anesthesia and monitoring the patient for reactions and complications, and to ensure comfort and manage pain. An anesthesiologist meets with the patient prior to the procedure to evaluate the patient's condition and review their medical history. The anesthesiologist also explains the process so the patient knows what to expect. During the procedure, the anesthesiologist carefully monitors the patient's vital signs and comfort and makes the appropriate adjustments in anesthesia. Following the procedure, the anesthesiologist continues to monitor the patient's vitals and may be involved in management of pain.

so basically they just put people to sleep or put a needle to the patien or put a mask so they cannot feel the PAIN
