未经证实:超声引导(US)外周静脉导管(PIVC)的故障率很高,许多在治疗完成之前就失败了。与导管失效相关的危险因素描述不充分。本研究旨在评估与导管失效相关的风险因素,包括患者,procedure,导管,和静脉特征,以进一步阐明哪些变量可能影响导管寿命。
UNASSIGNED:这是使用现有试验数据集的二次分析,主要比较了两种导管的存活率:标准长(SL)和超长(UL)USPIVC。研究参与者是三级护理郊区学术中心静脉进入困难的成年急诊室患者。采用Kaplan-Meier估计中位导管生存时间。Cox回归单变量和多变量分析用于评估导管生存的主要结果。
未经评估:在257个科目中,63%的PIVC存活直到治疗完成。在多变量Cox回归模型中,静脉导管长度>2.75cm(校正风险比[aHR]0.58,95%置信区间[CI]0.37-0.90,p=0.01)与生存率提高相关.首次穿刺成功降低了导管失败的风险(aHR0.68,95%CI0.44-1.06,p=0.09),但无统计学意义。与导管失败风险增加相关的因素包括:静脉深度>1.2cm(aHR1.68,95%CI1.06-2.66,p=0.03)和右肢PIVC放置(aHR1.64,95%CI1.07-2.51,p=0.02)。
UASSIGNED:本研究表明,静脉内导管长度(>2.75cm)与USPIVC生存率的提高相关,强调了在USPIVC生存率中导管长度较长的价值。在深度较浅的非优势肢体中选择目标(1.2cm)也可能会增加导管存活率。
UNASSIGNED: Ultrasound-guided (US) peripheral intravenous catheters (PIVC) have a high failure rate with many failing prior to completion of therapy. Risk factors associated with catheter failure are poorly delineated. This
study aimed to assess risk factors related to catheter failure including patient, procedure, catheter, and vein characteristics to further elucidate which variables may impact catheter longevity.
UNASSIGNED: This was a secondary analysis using an existing
trial dataset that primarily compared survival of two catheters: a standard long (SL) and an ultra-long (UL) US PIVC. Adult emergency room patients with difficult intravenous access at a tertiary care suburban academic center were
study participants. Kaplan-Meier was employed to estimate the median catheter survival time. Cox regression univariable and multivariable analyses were used to evaluate the primary outcome of catheter survival.
UNASSIGNED: Among 257 subjects, 63% of PIVCs survived until completion of therapy. In a multivariable Cox regression model, length of catheter in vein >2.75 cm (adjusted hazard ratio [aHR] 0.58, 95% confidence interval [CI] 0.37-0.90, p = 0.01) was associated with improved survival. First stick success decreased the risk of catheter failure (aHR 0.68, 95% CI 0.44-1.06, p = 0.09) but was not statistically significant. Factors associated with the increased risk of catheter failure included: depth of vein >1.2 cm (aHR 1.68, 95% CI 1.06-2.66, p = 0.03) and PIVC placement in right extremity (aHR 1.64, 95% CI 1.07-2.51, p = 0.02).
UNASSIGNED: This
study demonstrated that catheter length in vein (>2.75 cm) was associated with improved US PIVC survival highlighting the value of longer catheters in US PIVC survival. Choosing targets in the non-dominant extremity with shallower depths (⩽1.2 cm) may also increase catheter survival.
