目的 观察对重症急性胰腺炎（SAP）患者应用预防性护理后，对其病情康复及预后效果产生的影响。方法 选取医院收治的SAP患者共84例，按入院顺序分为对照组（42例）与观察组（42例），分别应用常规护理、预防性护理。对两组患者的病情康复及预后效果进行对比、评价。结果 ①观察组经过护理之后，腹胀和腹痛缓解时间、肛门排气、排便时间、住院时间都明显相对对照组更短，差异有统计学意义（P＜0.05）。②观察组经预防性护理以后的满意度比对照组的常规护理更高（97.62%vs.80.95%），差异有统计学意义（P＜0.05“,”Objective To observe the effect of preventive nursing on the recovery and prognosis of patients with severe acute pancreatitis(SAP).Methods A total of 84 patients with SAP in our hospital were selected and divided into control group(42 cases)and observation group(42 cases)according to the order of admission.The rehabilitation and prognosis of the two groups were compared and evaluated.Results(1)After nursing，the abdominal distension and abdominal pain relief time，anal flatus，defecation time，and hospital stay in the observation group were significantly shorter than those in the control group，and the difference was statistically significant(P＜0.05).(2)The observation group After preventive care，the satisfaction rate was higher than that of routine care in the control group(97.62% vs.80.95%)，and the difference was statistically significant(P＜0.05).(3)After preventive care，complications occurred in the observation group.The probability of the two groups of patients was significantly lower than that of the control group(4.76% vs.19.05%)，and the difference was statistically significant(P＜0.05).(4)Before nursing，there was no significant difference in pain，anxiety，depression and sleep quality in the two groups of patients.After nursing，the pain，anxiety and depression，and sleep quality of the patients in the two groups were improved，but the improvement effect of the observation group was more ideal than that of the control group，and the difference was statistically significant(P＜0.05).(5)Before nursing，there was no significant difference in the quality of life between the two groups，and both groups were improved after nursing，but the improvement in the observation group was more significant，and the difference was statistically significant(P＜0.05).(6)Before nursing There was no significant difference in the levels of serum prealbumin，serum albumin and C-reactive protein between the two groups(P＞0.05).After nursing，the patients in the two groups were improved，but the improvement in the observation group was more significant，and the difference was statistically significant(P＜0.05).Conclusion Predictive nursing can effectively shorten the symptom relief time of SAP patients，reduce the occurrence of complications，improve the overall satisfaction，reduce the pain of the patient\'s body，improve the psychological negative emotions and sleep quality，and can greatly improve the quality of life.It has been improved to optimize the patient\'s serum albumin，prealbumin，C-reactive protein and other levels.
