Objective To investigate the current status of uncertainty in illness in cardiac valvular surgery patients with cardiopulmonary bypass and analyze its influential factor,and provide reference for effective intervention.Methods A total of 208 cardiac valvular surgery patients with cardiopulmonary bypass were recruited from 4 cardiovascular surgery in Guangdong and were investigated with the self-designed questionnaire,Mishel Uncertainty in Illness Scale (MUIS),Connor-Davidson Resilience Scale (CD-RISC),Medical Coping Modes Questionnaire (MCMQ),in the preoperative day and the day before discharge.The data were analyzed by single-factor and multiple-factor analysis.Results The average score of uncertainty in illness in cardiac valvular surgery patients with cardiopulmonary bypass was 99.09±11.41,and 92.3％ of patients got a moderate uncertainty in illness level in the preoperative day.The average score of uncertainty in illness in the patients was 90.33± 10.32,and 91.8％ of patients got a moderate uncertainty in illness level in the day before discharge.Multiple linear regression indicated that,age,cardiac valvular disease types,number of cardiac valvular surgery,optimism and yield were the protective factors of uncertainty in illness level.Average monthly household income,self-improvement,scores of resilience and confront coping were the risk factors of uncertainty in illness level.Conclusion The level of uncertainty in illness in cardiac valvular surgery patients with cardiopulmonary bypass is moderate.Age,average monthly household income,cardiac valvular disease types,number of cardiac valvular surgery,resilience and coping style are factors influencing uncertainty in illness level of patients.

Objective To explore the relationship between resilience and coping style of cardiac valvular postoperative patients with cardiopulmonary bypass.Methods A total of 208 cardiac valvular postoperative patients with cardiopulmonary bypass were recruited from 4 cardiovascular surgery in Guangdong and were investigated with the self-designed questionnaire,Connor-Davidson Resilience Scale (CD-RISC),Medical Coping Modes Questionnaire (MCMQ).Results The average score of resilience in cardiac valvular postoperative patients with cardiopulmonary bypass was (55.38±10.63)points.The average score of tenacity,strength and optimism were (28.21 ±5.87)points,(18.21 ±4.02)and (8.96± 1.85)points respectively.The average score of coping style of confrontation,avoidance and acceptance-resignation were(18.13±3.38),(16.95±1.75)and (9.24±2.47)points respectively.All the sub-scores of the resilience were positively correlated with confrontation,and all the sub-scores of the resilience were negatively correlated with avoidance and acceptance-resignation.Conclusions There is a certain degree of correlation between resilience and copping style of cardiac valvular postoperative patients with cardiopulmonary bypass.Nurses should enhance resilience of the patients,guide the patients to adopt effective coping styles,to promote disease rehabilitation and improve the quality of life.
