胃肠减压在颅脑损伤患者头颅CT检查中的应用效果

目的 探讨胃肠减压在颅脑损伤患者头颅CT检查中的应用效果.方法 2015年5月至2016年4月,便利抽样法选取在解放军第464医院放射科需行头颅CT检查的急性重型颅脑损伤患者82例为研究对象.按随机数字表法将其分为对照组和观察组,每组41例患者.对照组患者行常规检查,不予胃肠减压;观察组患者以及CT检查前行持续胃肠减压.记录两组患者呕吐和干呕的发生情况、整个过程所用时间(留置胃管时间和CT检查时间)以及CT检查的一次成功率.结果 两组患者中均有2例患者发生干呕,差异无统计学意义(P＞0.05);观察组中无1例患者发生呕吐,而对照组中有7例患者发生呕吐,差异有统计学意义(P＜0.05).观察组患者整个过程用时为(28.5±5.96)min,对照组为(25.1士10.02)min,差异无统计学意义(P＞0.05).进一步分析显示,观察组患者CT检查所用时间为(19.3士4.40)min,明显少于对照组的[(25.1±10.02)min],差异有统计学意义(P＜0.05).观察组患者CT检查一次成功率为100％;对照组为85.4％,差异有统计学意义(P＜0.05).结论 持续胃肠减压能够明显减少急性重型颅脑损伤患者头颅CT检查时间,提高检查成功率,并减少CT检查时的呕吐发生,值得推广.

Application Effects of Gastrointestinal Decompression on the CT Examination for Patients with Craniocerebral Injury

Objective To discuss the application effects of gastrointestinal decompression on CT examination for patients with craniocerebral injury.Methods By convenience sampling,82 patients with serious brain trauma in our hospital were randomly selected and divided into control and observation groups,with 41 cases in each group.The observation group was given gastrointestinal decompression before the CT examination,while the control group received routine examination.The vomiting and vomiturition situation in patients and the time spent on gastrointestinal decompression operation and one time success CT examination were recorded.Results Two cases had vomiturition in both groups (P＞0.05).One case had vomiting in observation group,but there were 7 cases in control group with vomiting (P＜0.05).The time spent on the whole process was (28.5 ± 5.96)min,while the control group was (25.1 ± 10.02)min (P＞0.05).The further analysis showed that the CT examination in observation group was (19.3±4.40) min,and significantly less than control group of (25.1±10.02)min (P＜0.05).The one time CT examination rate in observation group was 100 ％,and the success rate was 85.4％ in control group (P ＜0.05).Conclusion Continue Gastrointestinal decompression can significantly reduce the incidence of vomiting in patients with acute severe craniocerebral injury during CT examination,and it can prevent patients from aspiration,which is worth for clinical promotion.
