Objective To discuss the application and effect of sufentanil combined with propofol on painless gastroscopy anesthesia.Methods In the fourth people's hospital of Zhejiang in April 2014-June 2016,94 cases treated with painless gastroscopy I were randomly divided into two equal groups.Anesthesia group A were anaesthetized with fentanyl and propofol,sufentanil and propofol for anesthesia group B.The anesthetic effect,the time of consciousness disappearance,eye opening time,recovery time of orientation,the dosage of propofol in the two groups were compared.The mean arterial pressure,heart rate and adverse reaction rate in the two groups were compared.Results The anesthetic effect in the anesthesia groupB is significant better than that in the anesthesia group A(P<0.05).Compared with the anesthesia groupA,the time of consciousness disappearance,eye opening and orientation recovery is shorter in the anesthesia groupB(P<0.05),The difference of the mean arterial drug Pressure and heart rate is not significant in the two groups before medication.After medication and wake up,compared with the anesthesia group A,the mean arterial pressure,heart rate fluctuation is smaller,and the adverse reaction rate is lower in the anesthesia group B,(P<0.05).Conclusion It is effective which sufentanil combined with propofol used in anesthesia in painless gastroscopy,It can stable vital signs of patients during operation,,work quickly,restore consciousness rapidly,and contribute to reduce complications,and is worthy of promotion.

Objective To investigate the clinical effect of direct extra-articular endoscopic excision of popliteal cyst using double posteromedial portals.Methods For 92 patients in our department who suffered from symptoms such as pain and discomfort in the popliteal fossa,limited knee flexion,swelling after activity,and were diagnosed with popliteal cyst based on imaging examinations from March 2017 to January 2023,we performed direct extra-articular endoscopic excision of popliteal cyst using double posteromedial portals.The recurrence of cysts was evaluated by MRI at last follow-up.The Rauschning and Lindgren classification was used to evaluate clinical outcomes.Results A total of 92 patients were included in the study.Arthroscopic examination revealed intra-articular lesions in 80 patients(86.96％),including degenerative cartilage lesion in 52 patients(56.52％),medial meniscus tear in 48 patients(52.17％),lateral meniscus tear in 28 patients(30.43％),anterior cruciate ligament injury in 17 patients(18.48％),chondromalacia patellae in 3 patients(3.26％),intra-articular loose body in 2 patients(2.17％),tibial intercondylar eminence fracture in 1 patient(1.09％),gouty arthritis in 1 patient(1.09％),synovitis in 3 patients(3.26％)and septic arthritis in 1 patient(1.09％).The average duration of symptoms was 11.71 months(0.03 to 120 months).All patients were followed up postoperatively,with an average follow-up period of 12.8 months(6 to 23 months).There were no serious complications such as deep vein thrombosis,neurovascular injury or infection.Two patients were found to have residual cysts by MRI at last follow-up.According to the Rauschning and Lindgren classification:pre-operation:13 cases of grade Ⅰ,53 cases of grade Ⅱ and 26 cases of grade Ⅲ;post-operation:74 cases of grade 0 and 18 cases of grade Ⅰ.Conclusion Direct extra-articular endoscopic excision of popliteal cyst using double posteromedial portals has several advantages,such as mini-invasion,fast recovery,short surgical time and low recurrence rate.
