目的探讨消化道肿瘤患者手术后强化落实超声药物渗透治疗的护理干预对患者术后快速康复的影响,为消化道肿瘤患者术后快速康复干预方案的制订提供参考。方法采用随机对照试验方法,于2021年4—7月,选择大连医科大学附属第二医院收治的消化道肿瘤术后患者120例为研究对象,按照随机数字表法分为对照组、分散治疗组以及集中治疗组,每组40例。对照组主要采用常规加速康复外科护理,并辅以早期康复训练;分散治疗组在对照组的基础上接受了超声药物渗透治疗的护理干预,每天上午和下午各进行1次,每次持续30 min;集中治疗组在对照组的基础上采取了一次性60 min的超声药物渗透治疗的护理干预。采用单因素方差分析、LSD-t.验和χ^(2)检验比较各组患者的胃肠道反应、肠道功能恢复情况、住院情况、术后并发症及护理满意度。结果对照组男27例,女13例,年龄(61.85±16.85)岁;分散治疗组男23例,女17例,年龄(60.90±16.88)岁;集中治疗组男23例,女17例,年龄(59.80±13.58)岁。分散治疗组和集中治疗组患者术后恶心、呕吐及腹胀症状持续时间、肠鸣音恢复时间、排气恢复时间及首次进食时间分别为(38.58±2.74)、(17.45±1.92)、(38.76±3.34)、(50.04±2.57)h和(36.79±2.58)、(16.48±1.85)、(36.98±2.28)、(48.25±3.07)h,均低于对照组的(43.13±3.56)、(21.24±2.50)、(42.65±3.78)、(52.21±3.15)h,差异均有统计学意义(t.为3.38~9.68,均Pt.为2.31~3.01,均Ph、(9.90±2.12)d和(7.35±2.13)h、(8.30±1.42)d,对照组分别为(4.39±1.53)h、(14.93±2.56)d,分散治疗组和集中治疗组患者下床活动时间、住院时间优于对照组,集中治疗组患者下床活动时间、住院时间优于分散治疗组,差异均有统计学意义(t.为-7.14~14.34,均P<0.05)。对照组术后肠梗阻的发生率为15.0%(6/40),而分散治疗组为5.0%(2/40),集中治疗组为0,差异有统计学意义(χ^(2)=7.50,P<0.05)。集中治疗组患者护理满意度达到了100.00%(40/40),分散治疗组和对照组分别为92.5%(37/40)和85.0%(34/40),差异有统计学意义(χ^(2)=6.49,P<0.05)。结论经过超声药物渗透治疗的护理干预,尤其是集中治疗方式的护理干预,可以显著改善消化道肿瘤患者术后肠道功能,减轻术后胃肠道反应,缩短住院时间,减少术后并发症的发生,加快患者康复,为临床提供有效的护理干预方案,值得推广应用。

为探究寒区砂岩在冻融循环作用下的孔隙结构损伤特性,对经历不同冻融循环次数的红砂岩试样进行了核磁共振试验,并结合多重分形理论,探讨了冻融循环作用对红砂岩不同尺度下孔隙结构的演化规律。结果表明:冻融作用促进了红砂岩孔隙结构发育,未经冻融作用的红砂岩t.2谱曲线呈3峰分布,经历冻融作用的红砂岩t.2谱分布曲线出现了4个峰,反映了冻融过程中红砂岩的孔隙结构演化复杂;单重分形不能表征红砂岩微小孔隙结构特征,但红砂岩微小孔和中大孔均具有良好的多重分形特征;分形参量与孔隙度高度线性相关。微小孔中总体非均质性参数D(0)-D(1)和低概率参数D(-10)-D(0)与孔隙度负相关,赫斯特指数h与孔隙度正相关;中大孔单重分形维数D 2与孔隙度负相关,D(0)-D(1)、D(-10)-D(0)、h均与孔隙度正相关;利用多重分形分析了冻融红砂岩孔隙结构演化规律,为深入研究冻融红砂岩损伤破坏机理提供了理论依据。
