Summary
Gastrointestinal tumor is one of the highest incidence of malignant tumors in our country,
with the incidence increasing year by year. Laparoscopic gastrointestinal surgery ,due to
having less bleeding ,small trauma ,Rapid recovery ,has become the main means for the
treatment of gastrointestinal surgery. Under general anesthesia, mechanical ventilation can
lead to repeated mechanical dilation of alveoli, which can lead to mechanical injury of
alveolar epithelium, reduce lung compliance, affect lung function, and increase postoperative
complications and hospital stay of patients. Glycopyrrolate acts selectively on M1 and M3
receptors, and is 3-5 times more selective to M3 and M1 receptors than M2 receptors.
Therefore, as preoperative medication for elderly patients, it has less effect on the
cardiovascular system and can stabilize the heart rate,compared with atropine.However, its
influence on the respiratory system in the field of anesthesia is only limited to the study
of inhibiting glandular secretion at present, and there are no clear reports on the study of
respiratory mechanics .The purpose of this study was to investigate the effects of
glycopyrrolate on lung function and respiratory mechanics in elderly patients after general
anesthesia, in order to guide clinical medication.
