Anesthesia complications can occur during or after a medical procedure when anesthesia is used to block pain. Common issues include allergic reactions, breathing difficulties, and changes in blood pressure. These complications can arise from the type of anesthesia used, the patient's medical history, or the nature of the surgery. In rare cases, more severe complications may happen, such as nerve damage or awareness during surgery. Anesthesiologists monitor patients closely to minimize risks and ensure safety. Understanding these potential complications helps patients make informed decisions about their care and prepares them for what to expect during their procedure.
