Effects Of No Background Dose Patient-controlled Analgesia Based On Micro-video Guidance On Postoperative Rehabilitation Of Patients With Day-surgery Cholecystectomy

Objective:The purpose of this study was to investigate the effect of patient-controlled intravenous analgesia without background dose based on based on micro-video guidance on the postoperative rehabilitation of patients undergoing daytime laparoscopic cholecystectomy.Methods:A total of 105 cases of patients undergoing day-surgery laparoscopic cholecystectomy were randomly divided into three groups:control group(N group),microvideo assisted fixed background dose PCIA group(VB group)and microvideo assisted no background dose PCIA group(VP group).The analgesic pump drug formulations were sufentanil 1.5μg/kg,tropisetron 5mg,diluted to 70ml with 0.9%sodium chloride injection.The VAS scores of 2 hours(T1),6 hours(T2),12 hours(T3)and 24 hours(T4)after operation,and the dosage of sufentanil in the analgesia pump at T1,T2,T3 and T4 were recorded.At the same time,the incidence of postoperative adverse reactions,the use of postoperative remedial analgesia measures,the score of QoR-15 scale,the overall satisfaction of patients and the time of first anal exhaust were observed.Results:Compared with group N,the consumption of sufentanil,the incidence of PONV,the score of QoR-15 and the overall satisfaction of patients in group VB and VP were significantly lower than those in group N,and the use rate of additional salvage analgesics in group VP was significantly lower than that in group VB.The first anal exsufflation time in group VP was significantly earlier than that in group VB(P<0.05).There was no significant difference in VAS score,incidence of adverse reactions such as drowsiness,skin pruritus and respiratory depression among the three groups(P>0.05).Conclusion:The purpose of this study is to explore the application of patient-controlled analgesia without background dose based on microvideo in daytime cholecystectomy,which can effectively reduce the dosage of opioids,reduce the pain of patients,reduce the occurrence of complications,and improve the quality of rehabilitation of patients.it is beneficial to the rehabilitation of patients after operation.
