Application of survival analysis model in predicting constipation relief in patients with thoracolumbar fractures after surgery / 中国实用护理杂志

ABSTRACT

Objective To investigate the incidence of postoperation constipation in patients who experienced thoracolumbar fractures screw fixation surgery.Methods A prospective cohort study was performed by investigating 99 cases who experienced thoracolumbar fractures screw fixation surgery.The patients were followed up for 1 month.The postoperative constipation relief situation was observed.Kaplan-Meier method was used to draw a plot of survival,Cox proportional hazards regression model analysis was adopted for single factor and multiple factors analysis and the prediction model of constipation relief after surgery was established.Results The trend of postoperative constipation relief of patients showed a trend of first increased and then decreased,the number of cases reached high peak on the second week,the constipation relief median time was (14.00±0.76) days.Cox multiple factors regression analysis showed that prediction function model of postoperative constipation relief was h(t)=[h0(t)]e(-0.826X1+0.353X2+0.381X3-1.404X4).Conclusions There was a high incidence of constipation in patients with thora-columbar fractures after surgery and it is difficult to relieve,clinical nurses should pay more attention to the influencing factors of postoperative constipation relief and help patients reestablish normal bowel movement as soon as possible.
