The clinical efficacy and prognosis of hemisphere skull bone flap decompression and mild hypothermia treatment for severe craniocerebral trauma

Abstract

In this study, 1626 patients with severe craniocerebral trauma were assessed by Glasgow Coma Scale (GCS, 886 patients of 3-5 score and 740 of 6-8 score). Patients were divided into 2 groups. Ninety hundred and eleven patients (496 of 3-5 score and 415 of 6-8 score) underwent hemisphere calvarial bone flap decompression with auxiliary mild hypothermia (experiment group), and 715 patients (390 of 3-5 score and 325 of 6-8 score) underwent traditional frontal, temporal, parietal large traumatic craniotomy (control group). After operation the treatment of 2 groups was basically the same. Compared with control group, the intracranial pressure of experiment group on the 1st, 3rd, 5th and 7th days after surgery decreased significantly (P < 0.05, for all); the consciousness recovery time was significantly shorter (P < 0.05, for all); the prognosis after 3 months was better (P < 0.05, for all). Hemisphere calvarial bone flap decompression with auxiliary mild hypothermia treatment could significantly reduce the morbidity and mortality, and improve the quality of life and prognosis of patients with severe craniocerebral trauma.
