چکیده

Arterial catheterization is a frequent proceeding in critically ill to obtain repetitively blood sampling and continuous monitoring of systemic arterial pressure arterial. The incidence of accidental catheter removal (ACR) in arterial catheters has been scarcely studied, and we did not find studies comparing the ACR incidence between femoral, cubital, dorsalis pedis and brachial arterial sites. The importance of ACR lies in that could cause severe complications, such as severe external haemorrhage and vascular damage, and some could be potentially life-threatening. Thus, due to the scarce published data and the possibility of severe complications in relation to ARC of arterial catheters we proposed this study. The objective of this study was to compare the incidence of ACR in femoral, cubital, dorsalis pedis and brachial arterial sites. We performed a retrospective study over seven years of all patients who were undergoing to femoral, cubital, dorsalis pedis or brachial arterial catheterization during their stay in the polyvalent Intensive Care Unit of the Hospital Universitario de Canarias, Tenerife, Spain. The study was approved by the institutional review board. The following data were collected: age, sex, diabetes mellitus, APACHE-II, diagnosis group, catheter access, catheter insertion and removal dates, and cause of catheter removal (planned or accidental). We considered accidental catheter removal as the presence of an unplanned removal produced by the patient or the staff. The ACR can be performed by the patient, either by taking hold of it with their hands or by making voluntary movements that led directly the removal. The ACR can be performed by the staff as consequence of inadequate handling. The catheters removed due to obstruction of the catheter were not considered as ACR. Statistical analyses were performed with SPSS 12.0.1 (SPSS Inc., Chicago, IL), LogXact 4.1 (Cytel Co., Cambridge, MA) and StatXact 5.0.3 (Cytel Co., Cambridge, MA). Continuous variables are reported as medians and percentiles 25th--75th, and were compared using Mann--Whitney test. Categorical variables are reported as frequencies and percentages, and were compared using Chi-square test. The incidence of ACR between groups was compared using Cox regression. The magnitude of the effects is expressed as Hazard Ratio (HR) and 95% confidence interval (CI). A p-value less than 0.05 was considered statistically significant. Were included a total of 2199 arterial catheters and remain in situ during 13,237 days. We detected 116 ACR, thus the 5.3% arterial catheters were accidentally removed and we had 0.88 ACR per 100 days of arterial catheterization. We found 49 events of ACR in 1250 (3.9%) arterial femoral catheters during 7524 days of catheterization (0.65 events of ACR per 100 days of catheterization), 39 events of ACR in 583 (6.7%) arterial cubital catheters during 3513 days of catheterization (1.11 events of ACR per 100 days of catheterization), 15 events of ACR in 198 (7.6%) arterial dorsalis pedis catheters during 1187 days of catheterization (1.26 events of ACR per 100 days of catheterization) and 13 events of ACR in 168 (7.7%) arterial brachial catheters during 1013 days of catheterization (1.28 events of ACR per 100 days of catheterization), As shown in Table 1, there were no significant differences between femoral, cubital, dorsalis pedis and brachial arterial catheters in age, sex, diabetes mellitus, APACHE-II, diagnosis group and duration of the catheter. However, there were found statistically significant differences in the percentage of catheters with ACR (p = 0.01) and in the ACR incidence per 100 days of catheterization (p = 0.02) between the different arterial sites. Cox regression analysis showed a lower ACR incidence in femoral than in cubital (Hazard Ratio = 0.608; 95% CI = 0.399--0.926; p = 0.02), dorsalis pedis (Hazard Ratio = 0.534; 95% CI = 0.299--0.952; p = 0.03) and brachial (Hazard Ratio = 0.500; 95% CI = 0.271--0.922; p = 0.03) arterial catheters (Table 2). To our knowledge, this is the first study comparing ACR incidence between femoral, cubital, dorsalis pedis and brachial arterial sites. The most relevant finding of our study is that femoral arterial catheter showed a lower ACR incidence that cubital, dorsalis pedis and brachial arterial catheters. In our study, we found that the 5.3% of arterial catheters were accidentally removed and an ACR rate of 0.88 events per 100 days of arterial catheterization. Our ACR rate is

Arterial catheter-related infection of 2,949 catheters

INTRODUCTION Which particular arterial catheter site is associated with a higher risk of infection remains controversial. The Centers for Disease Control and Prevention guidelines of 1996 and the latest guidelines of 2002 make no recommendation about which site or sites minimize the risk of catheter-related infection. The objective of the present study was to analyze the incidence of catheter-r...

Lesser incidence of accidental catheter removal with femoral versus radial arterial access.

BACKGROUND Arterial catheterization is a frequent procedure in Intensive Care Units (ICUs). Accidental catheter removal (ACR) can cause severe and potentially life-threatening complications such as severe bleeding and vascular damage. Few data are available on accidental arterial catheter removal, and no studies have been found comparing the incidence of ACR between different arterial catheter ...

Quantitative ultrasonographic studies of lower extremity flow velocities in health and disease.

Quantitative Doppler ultrasonographic flow velocity determinations are reported from 39 normal control subjects and 80 patients with angiographically documented peripheral arterial disease, in whom femoral, posterior tibial and dorsalis pedis arteries were studied. The mean control values of the most useful parameters were: femoral artery: peak forward velocity (PFV) cm/sec: 40.7 +/- 10.9, dece...
