Objective:To explore and optimize the management process of bladder irrigation for patients after greenlight photoselective vaporization (PVP) , reduce the occurrence of postoperative complications, and improve the satisfaction of patients and nurses for bladder irrigation.Methods:Totally 315 patients undergoing PVP in the Department of Urinary Surgery, the Second Hospital of Hebei Medical University from May 2017 to April 2019 were selected using purposive sampling. A total of 153 patients admitted from May 2017 to April 2018 were divided into the control group, who received routine bladder irrigation management, while 162 patients admitted from May 2018 to April 2019 were divided into the observation group, who received bladder irrigation management by the failure mode and effect analysis. The incidence of complications such as bladder spasm and urinary tract obstruction, the duration of continuous bladder irrigation, and patient satisfaction were compared between the two groups, and the nurse satisfaction before and after the process optimization was compared.Results:After the process optimization, the incidence of bladder spasm decreased from 17.0% (26/153) to 8.0% (13/162) , the incidence of urinary tract obstruction decreased from 11.8% (18/153) to 3.7% (6/162) , and the differences were statistically significant (χ 2=5.835, 7.264; P<0.05) . The duration of bladder irrigation was shortened from (25.311±2.295) h to (22.422±1.481) h, and the difference was statistically significant ( t=13.348, P<0.05) . After optimizing the bladder irrigation management process, the nurse satisfaction score was (34.221±5.124) , and the patient satisfaction score was (37.113±6.108) , both higher than those before the optimization, and the differences were statistically significant ( t=19.817, 14.546; P<0.05) . Conclusions:Optimizing the bladder irrigation management process for patients after PVP using the failure mode and effect analysis can reduce the incidence of postoperative bladder irrigation complications, shorten the duration of bladder irrigation, and improve patient and nurse satisfaction.
