Study on the trauma and stress level of the pelvic fracture treated by 3D printing combined with lateral rectus abdominis approach surgery

摘要

Objective: To study the trauma and stress level of the pelvic fracture treated by 3D printingcombined with lateral rectus abdominis approach surgery. Methods: A total of 50 patientswith pelvic fractures who were treated in the hospital between July 2015 and Jun 2017 werecollected anddivided into control group (n=25) and observation group (n=25) by randomnumber table method. Control group underwent lateral rectus abdominis approach surgery,and the observation group received 3D printingcombined with lateral rectus abdominisapproach surgery. The differences in perioperative inflammatory response, coagulationfunction and stress degree were compared between the two groups. Results: 24 h beforesurgery, the differences in inflammatory response, coagulation function and stress degree werenot statistically significant between the two groups. 24 h after surgery, serum IL-1, TNF-α,CRP, FIB, D-D, Cor, AngⅡ and NE levels of both groups of patients were higher than those24h before surgery, and serum IL-1, TNF-α, CRP, FIB, D-D, Cor, AngⅡ and NE levels ofobservation group were lower than those of control group. Conclusion: 3D printing combinedwith lateral rectus abdominis approach surgery can effectively reduce the degree of surgicaltrauma and reduce the systemic stress response in patients with pelvic fracture.
