Precautions for intraoperative anesthesia for pituitary tumor include maintaining hemodynamic stability, avoiding folding of tracheal tube, maintaining muscle relaxation and eye care. 1. Maintaining hemodynamic stability: patients need to maintain hemodynamic stability during anesthesia for pituitary tumor surgery, and at this time, it is necessary to pay attention to monitoring the patient’s blood pressure, heart rate, respiration and so on, so as to adjust the depth of anesthesia in time. 2. Avoid the folding of tracheal tube: patients with pituitary tumor should avoid the bending and folding of tracheal tube because of surgical operation or change of body position during the operation. 3. Maintaining muscle relaxation: it is also necessary to maintain good muscle relaxation during the operation of pituitary tumor, therefore, it is necessary to follow the doctor’s instruction to use muscle relaxants, such as vecuronium bromide, pancuronium bromide and so on, in time during the operation. 4. Eye care: due to the interaction between general anesthesia and muscle relaxants, the patients will have incomplete eyelid closure during the operation, coupled with the unavoidable penetration of disinfectant into the eyes during the disinfection process, and the spreading of towels or dressings may also rub the eyes, which may lead to tingling in both eyes, photophobia, and tearing in both eyes after the operation. Medical adhesive tape is needed to paste the eyelids during the operation, and eye ointment or eye gel is used for protection. Pituitary tumor intraoperative anesthesia also need to pay attention to the patient’s condition changes, according to the patient’s condition to adjust the dose of anesthesia. It is recommended that patients choose regular hospitals for pituitary tumor surgery, and under the guidance of doctors.
