Objective To explore the effect of propagating and educating (planning, doing, checking, and acting) circulation combined with neuronavigation system on improving surgical coordination at perioperative nursing in patients with pituitary tumors. Methods One hundred and sixteen patients with pituitary tumors, admitted to and accepted neuronavigation assisted microsurgery in our hospitals from August 2016 to August 2018, were chosen in our study; these patients were randomly divided into experimental group and control group (n=58). Patients from the control group accepted traditional perioperative propagating and educating circulation, while patients from the experimental group accepted perioperative propagating and educating (planning, doing, checking, and acting [PDCA]) circulation. Awareness rate of surgical preparation knowledge, self-rating anxiety scale (SAS) scores, degrees of operation coordination, length of hospital stays, hospitalization cost and postoperative complications were compared between the two groups. Results As compared with patients in the control group, patients in the experimental group had significantly higher knowledge of surgical preparation, statistically lower SAS scores and statistically lower proportion of patients with poor surgical coordination (P<0.05). As compared with those in the control group, the hospitalization cost, length of hospital stays and incidence of surgical complications (5.1％ vs. 12.1％) in the experimental group were statistically decreased (P<0.05). Conclusions PDCA circulation combined with neuronavigation system can be used as a kind of brand-new education mode for patients with pituitary adenomas. As compared with traditional perioperative mode, the new mode can significantly improve the awareness rate of surgical preparation knowledge, relieve anxiety level, improve cooperation degree, and reduce the postoperative complications, length of hospital stays, and hospital expenses, which means great clinical significance.
