General anesthesia in the 70s has no sequelae in most cases, but a small number of patients can experience dizziness, nausea and other symptoms.
With the gradual progress of anesthesia technology, related monitoring technology, general anesthesia technology is relatively mature, most patients will not have sequelae after experiencing general anesthesia. While some of the elderly, cardiopulmonary function is relatively poor, anesthesia risk is greater, may wake up with dizziness, headache, nausea and other symptoms, usually in a few hours after the gradual disappearance.
Before general anesthesia patients should improve the preoperative examination, including cardiopulmonary function, CT, magnetic resonance imaging examination, in order to assess the risk of anesthesia. Patients who are older, with poor cardiopulmonary function and poor tolerance to anesthetics need to have their vital signs closely monitored after surgery.
Patients are advised to choose regular hospitals for general anesthesia operation to reduce possible risks.
