目的：探讨砂袋压迫止血时间长短对颈动脉内膜剥脱术后出血及患者舒适的影响。方法将2014年1月至2015年9月在我院行颈动脉内膜剥脱术患者112例按入院顺序分为对照组36例、试验1组36例和试验2组40例。术后对照组砂袋压迫24 h，试验1组压迫12 h，试验2组压迫6h。观察各组患者术后皮下血肿、切口渗血发生率。采用焦虑自评量表评估患者焦虑状态，采用数字疼痛评分法评估患者肩颈僵硬及疼痛状况。结果3组患者伤口出血即血肿、渗血发生率无明显差异（P>0.05）；术后24 h试验2组患者焦虑和肩颈酸痛评分分别为（51.43±8.18）、（1.28±1.06）分，明显优于对照组的（56.64±7.08）、（2.31±1.17）分，2组比较差异有统计学意义（t=2.96、4.03， P<0.05）；术后24 h试验1组患者焦虑和肩颈酸痛评分与对照组比较差异无统计学意义（P>0.05）。结论颈动脉内膜剥脱术后砂袋压迫6 h能有效止血，同时改善患者的焦虑及肩颈僵硬疼痛等不适状态。

Objective To explore the efficacy of oppression hemostsis time on hemorrhage and patient comfort after carotid endarterectomy. Methods Patients with carotid artery stenosis from January 2014 to September 2015 were enrolled.The patients were divided into three groups according to oppression hemostasis time:control group for 24 hours,experimental group one for 12 hours,experimental group two for 6 hours.The outcomes were the incidence of hematoma,errhvsis,anxiety,and neck pain. Results No significant differences were observed in hematoma and errhysis among these three groups.The total scores of anxiety and neck pain of experimental group two were (51.43±8.18) points,(1.28±1.06) points,obviously surpassed the comparison group (56.64 ± 7.08) points,(2.31 ± 1.17) points,showed a significant decrease in two groups (t=2.96, 4.03, P<0.05). The total scores of anxiety and neck pain of experimental group one were (54.14±8.99) points,(1.97±0.97)points,showed no significant in compared with comparison groups(t=1.31, 1.32, P>0.05). Conclusions The preferred option for oppression hemostasis time is 6 hours that has an effective hemostasis with a favorable patient comfort.
