The invention discloses a method for relieving
neurosurgery postoperative agitation under a
sevoflurane general
anesthesia condition. The method comprises steps as follows:
intramuscular injection of 0.06 mg*kg<-1> of
midazolam and 0.3 mg of
scopolamine is performed on a patient 30 min before an operation, and the
venous access is open after entrance;
anesthesia induction: intravenous injection of 0.03 mg*kg<-1> of etomidate, 5 mu g*kg<-1> of
fentanyl and 1 mg*kg<-1> of atracurium is performed on the patient;
anesthesia maintenance: 3%-5% of
sevoflurane is inhaled, the
oxygen flow is 1.5 L / min, the concentration of
sevoflurane is monitored by an anesthesia gas monitor, the MAC (minimum alveolar concentration) value is controlled within 1.3-1.5, continuous intravenous infusion of 2 mg*kg-1*h<-1> of
propofol is performed, the
blood pressure is controlled to be 20%-25% of the basic
blood pressure, and discontinuous intravenous injection of atracurium is performed for maintaining muscular relaxation. During the operation, a Datex
ECG monitor is adopted to perform routine monitoring of
respiration and circulation functions,
arterial blood gas analysis and
electrolyte check are performed, and the
homeostasis is maintained.
Inhalation of sevoflurane is stopped 10 min before the operation is ended, and
phlegm suction extubation is performed when autonomous
respiration tidal volume is larger than 8 ml*kg-1, the blood
oxygen saturation is larger than 95% and
swallowing reflex recovers.
