Comparison of time efficiency of new-type homemade 16-slice mobile CT and conventional CT in the neurosurgery intensive care unit

Abstract

Objective To investigate the time efficiency of new-type homemade 16-slice mobile CT in head scan in the neurosurgery intensive care unit. Methods From 20 August 2019 to 30 August 2019, 60 patients from Department of Neurosurgery Intensive Care Unit of Sichuan Provincial People’s Hospital, performed head CT scan according to the needs of the disease. They were divided into a mobile CT group and a conventional CT group, according to the random digital table method, 30 patients in each group. The data, including 16-slice mobile CT and large-scale CT scanning time, frequency of propofol usage, total non-reactive scale score (FOUR), manpower required for scanning, and CDTIvol, was recorded and compared. Results Two groups of patients have little heterogeneity including sex composition, age and FOUR scores(P<0.05). Compared with the scan results of conventional CT, the head CT scan in mobile CT group showed that the imaging quality is stable, clearly showing brain contusion, intracranial hematoma, cerebral infarction, skull fractures and other lesions, and it can meet the daily diagnostic requirements of the intensive care unit. Time consuming of mobile CT[(15.53±4.72) min] was significant shorter than ones of the conventional CT group [(34.30±6.48) min] and the workload is significantly less, and the difference was statistically significant (P<0.05). There was more frequency of propofol use in mobile CT group, and the difference was statistically significant (P<0.05). Conclusion The 16-slice mobile CT has the advantages of being safe, convenient, reliable in performance and excellent in imaging quality in the intensive care unit.
