Abstract:〔Abstract〕 Objective To analyze and evaluate the clinical effect of predictive nursing during the nursing of postoperative hydrocephalus in patients with aneurysmal subarachnoid hemorrhage. MethodsA total of 80 patients with aneurysmal subarachnoid hemorrhage admitted to the First People's Hospital of Shangqiu from January 2020 to June 2022 were selected and divided into two groups by random number table method, with 40 cases in each group. The control group was given routine nursing, and the observation group was given predictive nursing based on routine nursing. The nursing effects of the two groups were compared. Results After nursing, the cognitive function and prognosis scores of the observation group were higher than those of the control group, and the brain dysfunction and neurological deficit scores were lower than those of the control group, and the differences were statistically significant (P < 0.05). The incidence of complications in the observation group was 2.50 %, which was lower than 17.50 % in the control group, and the difference was statistically significant (P < 0.05). Conclusion The application of predictive nursing during the nursing of postoperative hydrocephalus in patients with aneurysmal subarachnoid hemorrhage has a positive significance for improving the prognosis of patients. It can prevent complications while promoting the recovery of cognitive function and neurological function, which is conducive to improving brain dysfunction.
