智能负压吸引技术与中心负压吸引技术在骶尾部压力性溃疡治疗中的疗效观察

Therapeutic effect of intelligent vacuum technique and central negative pressure technique in the treatment of pressure ulcer in sacrococcygeal region

目的:观察智能负压吸引技术和中心负压吸引技术在骶尾部压力性溃疡中的临床效果。方法:选取我科2017年1月至2019年6月骶尾部压力性溃疡患者50例,随机分为观察组、对照组,每组25例,其中观察组在彻底清创后使用智能负压,对照组清创后使用中心负压。观察两组术区的出血、贴膜漏气、术区疼痛情况。结果:在出血方面,观察组出血1例,出血率4%,对照组出血6例,出血率24%,两组比较,差异有统计学意义(P<0.05)。在膜漏气方面,观察组漏气2例,漏气率4%,对照组漏气8例,漏气率32%,两组比较,差异有统计学意义(P<0.05)。在疼痛评分上,术后第2天观察组(3.44±0.92)分,对照组(5.28±1.40)分,两组比较,差异有统计学意义(P<0.05);术后第4天观察组(2.56±1.29)分,对照组(4.24±1.33)分,两组比较,差异有统计学意义(P<0.05);术后第6天,观察组(1.72±1.06)分,对照组(1.76±1.36)分,两组比较,差异无统计学意义(P>0.05)。结论:智能负压技术较中心负压技术能明显降低术区出血、贴膜漏气的发生,同时在负压安装早期能减轻患者疼痛,晚期两组无差别。在骶尾部压力性溃疡治疗上智能负压技术优于中心负压技术。

Objective:To observe the clinical effect of intelligent vacuum technique and central negative pressure technique in the treatment of pressure ulcer in sacrococcygeal region.Methods:50 patients with pressure ulcer in sacrococcygeal region of our hospital were selected from January 2017 to June 2019.They were randomly divided into observation group and control group.Each group included 25 patients,the observation group was used intelligent vacuum technique after thorough debridement,and the control group used central negative pressure technique after debridement.The bleeding,membrane leakage,and pain in the operation area of the two groups were observed.Results:In the aspect of bleeding,observation group had 1 case,the bleeding rate was 4%;and the control group had 6 cases,the bleeding rate was24%.There was significant difference(P<0.05)between the observation group and the control group.In terms of membrane leakage,the observation group leaked 2 cases and the air leakage rate was 4%.In the control group,8 patients had air leaks and the air leakage rate was 32%.The observation group was statistically significant(P<0.05)compared with the control group.On the patient’s pain score,the observation group(3.44±0.92)and the control group(5.28±1.40)were statistically significant(P<0.05)at the 2nd day after surgery.Similarly,the observation group(2.56±1.29)and the control group(4.24±1.33)were statistically significant(P<0.05)at the 4th day.However,there was no statistical significance(P>0.05)between the observation group(1.72±1.06)and the control group(1.76±1.36)at 6th day.Conclusion:Compared with the central negative pressure technique,the intelligent vacuum technique can significantly reduce the occurrence of hemorrhage and membrane leakage in the operation area.At the same time,it can also alleviate the pain in the early stage of negative pressure installation.But there is no difference in the late stage.Therefore,intelligent vacuum technique is superior to central negative pressure technique in the treatment of pressure ulcer in sacrococcygeal region.
