Using umbilical artery catheters with the hole in the side instead of end leads to serious complications. The umbilical artery catheters (tubes) (UACs) commonly used in neonatal intensive care to monitor babies can sometimes cause them problems. They can be used with different accompanying doses of the drug heparin, and in different positions. The design of catheters can vary. The review found that catheters with a hole in the side instead of at the end resulted in one in three babies experiencing aortic thrombosis (a clot in the heart's major artery).
อ่านบทคัดย่อฉบับเต็ม
Umbilical arterial catheters (UACs) are among the most commonly used monitoring methodologies in neonatal intensive care. Immediately after insertion of a UAC, local vascular compromise is frequently evident, usually in the form of blue or white toes, but occasionally with more severe and extensive ischemic manifestations. Aortic thrombi and renal ischemia have also been described. Some epidemiologic and case control studies have shown that the use of umbilical artery catheterisation is statistically associated with the later development of necrotizing enterocolitis.
วัตถุประสงค์
To determine whether the design of an umbilical arterial catheter influences the frequency of ischemic events, aortic thrombosis, intraventricular hemorrhage, mortality or necrotising enterocolitis in newborn infants.
วิธีการสืบค้น
Randomized and quasi-randomized controlled trials of umbilical catheterization use were obtained using the search methods of the Cochrane Neonatal Review Group. The Cochrane Library, MEDLINE (search via PubMed), CINAHL and EMBASE were searched from 1999 to 2009.
เกณฑ์การคัดเลือก
Randomized trials in newborn infants of any birthweight or gestation.
Comparison of end hole catheters with side hole catheters.
Clinically important end points such as ischemic events or aortic thrombosis.
การรวบรวมและวิเคราะห์ข้อมูล
There appears to be only a single trial which has addressed this issue (Wesstrom 1979).
ผลการวิจัย
End hole catheters are associated with a much decreased risk of aortic thrombosis compared to side hole catheters. RR = 0.27 (95% CI 0.11, 0.67)
ข้อสรุปของผู้วิจัย
Side hole catheters should be avoided for umbilical arterial catheterisation in the newborn.
