Can a little sputum be used for general anesthesia? This question is rather general, because the anesthesiologist will do a comprehensive assessment of the patient’s respiratory system function based on the patient’s condition, judged by the patient’s relevant examination and auscultation, and consider whether the patient can tolerate general anesthesia in combination with whether the patient’s surgery is an emergency or elective surgery. If only a little bit of sputum can be done for general anesthesia, but sometimes a comprehensive assessment of the patient, such as doing ASA assessment, the patient is a 3-4 level patient, sputum may cause intraoperative complications of lung infection, postoperative lung infection, so at this time it is best to treat the patient’s lung condition, and then come to the patient on the anesthesia will be safer. If a patient with ASA score 1-2 has a little bit of sputum, just a little bit of sputum, you can still go on general anesthesia. If a child has a cold and just a little sputum, it is also recommended to postpone general anesthesia and surgery for a few days, because there is a possibility of severe high airway reaction during surgery, resulting in bronchospasm, asphyxia and hypoxia in children.
