新型国产16排移动CT和常规CT在神经重症监护室临床应用的时效性比较

目的探讨国产16排移动CT在神经外科监护室进行头颅CT扫描诊断的时效性。 方法选取四川省人民医院神经外科重症监护室自2019年8月20日至30日收治的60例患者，根据病情需要进行头颅CT扫描，按照随机数字表法分为移动CT组和大型CT组，每组30例。分析对比16排移动CT与大型CT扫描时间、丙泊酚使用频次、全面无反应性量表评分（FOUR评分）、扫描所需人力、容积CT剂量指数（CDTIvol）。 结果2组患者性别组成、年龄及FOUR评分差异无统计学意义（P<0.05）。移动CT与大型CT头颅CT扫描结果相比，成像质量均稳定，清晰显示脑挫裂伤、颅内血肿、脑梗死、颅骨骨折等病灶，满足重症监护室日常诊断需求。移动CT每次扫描所需的时间[（15.53±4.72）min]、人力[（3.47±0.57）人/次]也明显少于大型CT组[（34.30±6.48）min，（5.90±0.71）人/次]，差异具有统计学意义（P<0.05），通过线性回归明确CT类型不同是扫描时间差异的主要原因。移动CT组丙泊酚使用频次多于大型CT，差异具有统计学意义（P<0.05）。移动CT与大型CT对比CDTIvol更小。 结论16排移动CT在监护室病房使用具有安全便捷、性能可靠、成像质量优良的优势。

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

ObjectiveTo investigate the time efficiency of new-type homemade 16-slice mobile CT in head scan in the neurosurgery intensive care unit. MethodsFrom 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. ResultsTwo 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). ConclusionThe 16-slice mobile CT has the advantages of being safe, convenient, reliable in performance and excellent in imaging quality in the intensive care unit.
