Objective To investigate the influence of experience teaching used in clinical nursing on the comfort feeling of bedridden patients .Methods Totals of 46 nurses from four wards of cardiology were applied the experiential education .Totals of 228 cardiovascular patients met the inclusion criteria were recruited from February to December 2011.Totals of 115 patients, from July to December 2011, were in the intervention group, while 113 patients, from February to June 2011, were in the control group.General information questionnaire and the comfortable status scale were used .Results In the control group , the scores of each dimension of physical comfort , psychological comfort , social comfort , comfortable environment and the total score were (13.04 ±2.512), (20.27 ±5.184), (19.92 ±2.991), (18.58 ±3.017) and (71.81 ±9.570), respectively.Those scores in the intervention group were (15.76 ±2.258), (29.87 ±3.582), (23.21 ± 1.935), (20.37 ±1.903) and (89.21 ±7.283),respectively.There were significant differences between the two groups (t=8.577, 16.298, 9.872, 5.367, 15.461, respectively;P<0.05).Conclusions It is feasible and effective for the hospital to apply experience teaching .

Objective To compare the effect of posterior cruciate ligament retaining(CR)and posterior cruciate substituting(PS)prosthesis in knee arthroplasty.Methods 64 patients with knee osteoarthritis were admitted to our department from June 2021 to June 2022 and whom met the selection criteria were randomly selected and divided into observation group and control group(n = 32).CR prosthesis was used in the observation group,and PS prosthesis was used in the control group.Operation time,postoperative drainage volume,difference of hemoglobin(HGB)before and after operation,postoperative hospital stay,postoperative range of motion at 7 d,14 d,45 d,3 months and 1 year were recorded.ROM,visual analog pain Scale(VAS),Hospital for special surgery(HSS)score,and maximum forward and backward displacement of knee joint and the regular radiographs were also recorded,too.Results The two groups were similar in terms of operation time,postoperative hospital stay,postoperative VAS score and maximum anterior and posterior displacement of knee joint,with P values greater than 0.05,which had no statistical significance.The postoperative drainage volume in the observation group was significantly less than that in the control group,with statistical significance(P＜0.05).The HGB difference of observation group was significantly lower than that of control group,with statistical significance(P＜0.05).There was no statistically significant differ-ence in ROM and HSS scores between the two groups before surgery;the ROM and HSS scores of the control group at 7,14 and 45 days after surgery was better than that of the observation group,with statistical significance(P＜0.05);the ROM and HSS scores of the two groups at 3 months after surgery was not statistically significant.The ROM and HSS scores in the observation group was better than that in the control group at 6 months and 1 year after operation,and the difference was statistically significant(P＜0.05).Conclusions CR prosthesis is superior to PS prosthesis in terms of intraoperative blood loss and post-operative drainage volume,which can reduce surgical risk.Both kinds of prosthesis can achieve good knee stability after surgery,while PS prosthesis has better early clinical effect,while CR prosthesis has better long-term clinical effect.
