Abstract: ［Abstract］ Objective To explore the value of simple lung function test in elderly patients undergoing painless enteroscopic multiple polypectomy. Methods According to preoperative pulmonary function test results， one hundred and eighty elderly patients were selected and divided into normal pulmonary function （A group， n=108）， mild?moderate abnormal pulmonary function （B group， n=47） and severe abnormal pulmonary function （C group， n=25）. The heart rate （HR）， respiratory rate （RR）， mean arterial pressure （MAP）， blood oxygen saturation （SpO2） were compared with different time point， pre?dose （T1）， colonoscopy （T2）， treatment start 10 min （T3）， retrospective （T4）， leaving the operating room （T5）. The operating time， recovery time， and residence time of the postoperative recovery room （PACU） were recorded. Intraoperative ephedrine， atropine and propofol dosage and adverse reactions， including respiratory depression and hypotension， were recorded. Results Compared T2 with T1 time point， MAP， MAP， and SpO2 decreased in group A and group B|however， in group C， all indexes， including MAP， SpO2， HR and RR， decreased in group C （P<0.05）. Compared with group A and group B， the recovery time and the residence time of PACU was longer in group C （P<0.01）. Compared with group A and B， the incidence of adverse reactions and the use of vasoactive drugs in group C was higher， and the use of atropine and ephedrine increased （P<0.01）. Conclusion Patients with pulmonary insufficiency have an increased adverse reaction to polypectomy under painless colonoscopy. Simple lung function tests are important for the assessment of elderly painless intestinal polypectomy.
