Trauma at the time of insertion of an UA catheter caused by endothelial injury is postulated to be the cause of aortic thrombus formation, with clot embolization to the kidneys, causing localized areas of infarction and increased renin release. Tne brachial artery should not be cannulated (inadequate collateral circulation), and the femoral artery should be used only as a last resort. Emergent need for vascular access (i.e., resuscitation), Frequent blood sampling in unstable patient without other access. Air might be introduced inadvertently into the intrahepatic portal venous system at the time of umbilical venous catheter insertion. Both systemic vasodilators and topical vasodilators have been described as having some efficacy in this situation, but definitive evidence for efficacy is lacking.43,44 When a significant clot is identified, thrombolysis with tissue plasminogen activator, infused either directly into the affected vessel or systemically, has been attempted.45,46 The potential advantages of thrombolytic therapy must be weighed against the risks of such therapy, particularly in the infant with a preexisting intracranial hemorrhage that could potentially extend. Umbilical venous catheterisation (UVC) insertion documentation is to be completed by the individual inserting the device in CVAD insertion/removal record in eMR and/or in patient’s progress notes.

An umbilical artery catheter is most often used if: The baby needs breathing help. Cleanse the umbilical insertion site with an antiseptic before catheter insertion. By, Grasping the catheter with a forceps or between the thumb and forefinger, the catheter can be inserted into the lumen of the dilated artery. Initial treatment includes anticoagulation with heparin and fluid resuscitation. Prime both lumens where appropriate. Peer Review Status: Internally Peer Reviewed. Commonly used methods are … Associated signs may include acute kidney injury (AKI) in patients with bilateral involvement, hematuria, and loss of femoral pulses and blood flow to the lower extremities in patients with extensive aortic thrombosis. This trial compared removal of an umbilical venous catheter within 10 days after insertion (and replacement with a peripheral cannula or a percutaneously inserted central catheter as required) versus expectant management (UVC in place up to 28 days). Unfortunately, there is little literature available regarding the optimal approach to infants with severe vascular obstruction. Catheterize vessel after cutdown technique, using 3.5 F (<1500 g) or 5 F catheter. A major risk factor for renal arterial obstruction is. An x-ray will be taken to make sure the catheter is in the right place. Duplex Doppler renal ultrasound is an appropriate initial study to provide a noninvasive and accurate diagnosis. Yacov Rabi MD, FRCPC, ... Namasivayam Ambalavanan MBBS, MD, in Assisted Ventilation of the Neonate (Sixth Edition), 2017, Although umbilical artery catheterization is safe and well tolerated in most patients, it is important to remember that it is not without risks. Avoid infusion or injection of hypertonic solutions (e.g., sodium bicarbonate) unles catheter tip is above diaphragm. High—Tip should be above diaphragm and below right atrium in the vena cava for indwelling use. If the radial artery is to be cannulated, an Allen test should be performed to ensure ulnar artery patency. Umbilical catheter placement is a routine neonatal emergency procedure that has large variability in technical methods. Among adolescents, blunt or deceleration injury with stretching and dissections of the renal artery is a common cause of an acute occlusion. Use low tonicity fluid (i.e., 0.45% sodium chloride). Although the majority of patients with dusky toes have adequate perfusion and suffer no ill effects, one must always be aware of the risk that this represents potential significant vascular compromise. This must include the catheter type, size and tip location and other relevant fields listed. The needle is then withdrawn. Suggested order of preference for vessels to cannulate: Median antebrachial, accessory, or cephalic veins of forearm, Basilic or cubital veins of antecubital fossa, Small saphenous or great saphenous veins of ankle, Supratrochlear, superficial temporal, or posterior auricular veins of scalp. Using a scalpel, the cord is cut cleanly 1.0 cm from the skin. Cardinal Health’s Argyle™ Umbilical Catheter Insertion Trays feature single and dual lumen options in 3.5 or 5.0 Fr sizes. It is considered the standard of care for arterial access in neonates. An umbilical catheter with a single end hole may be used for the catheterization of either umbilical artery or vein. HTN may develop either while the catheter is in place or long after its removal and may be associated with a history of renal insufficiency or gross hematuria. The catheter is withdrawn until its tip reenters the vessel lumen and a brisk blood return is obtained, at which point it is threaded into the vessel. Failure to recognize worsening perfusion may result in necrosis and loss of a portion of the foot. Although several studies that have examined the duration of line placement and line position (“low” vs “high”) as factors involved in thrombus formation, the data have not been conclusive. This placement is traditionally preferred. Failure to recognize worsening perfusion may result in necrosis and loss of a portion of the foot. It passes through the umbilicus, umbilical vein, left portal vein, ductus venosus, middle or left hepatic vein, and into the inferior vena cava.

Infants with umbilical artery catheters in place will occasionally develop dusky or purple discoloration of their toes, presumably from microemboli or vasospasm. On most occasions, it is advantageous to place a double lumen UVC. Many centers prefer use of low-dose heparin (0.5 to 1.0 units/mL) to decrease risk of clotting. Apply tourniquet if placing in extremity. The infant's abdomen and cord are cleaned with alcohol. Vygons’ umbilical catheters are expertly designed for use with small neonates who need venous or arterial catherisation after birth. Look for blanching of skin over vessel when fluid is infused, suggesting arterial spasm. If a "blue leg" develops (presumably from vasospasm), the catheter should be removed or carefully observed for a short period of time to allow for resolution of the impaired circulation. Trainees inserting catheters must have undergone competency based assessment for insertion of umbilical lines and for taking blood samples from arterial catheters (DOPS) or they must be supervised by a middle grade or senior colleague who is skilled in these procedures. Acute thrombosis of an otherwise nondiseased renal artery resulting in interruption of blood flow for more than 90 minutes invariably results in an irreversible loss of renal function. A concern of umbilical artery catheters is the effect of blood sampling on cerebral blood flow. Because blanching represents severely compromised arterial blood flow, the catheter should be immediately removed. Sterile drapes are placed. Sterile technique must be observed; the use of goggles (or eyeglasses) is recommended. The cord is elevated vertically using the toothed forceps. The catheter will be passed into place. For babies less than 500 grams, 3.5 Fr double lumen catheters are available. Watch for pulsations to stop. Embolization of formed clot with vigorous flushing. There is a recent trend in increased longer-term use in ELBW infants. There is little published data on which to base decisions about how long an umbilical artery catheter can remain safely in place. Remove stylet and advance needle into vessel. Lower placement avoids the complication, but causes a higher incidence of ischemia to the legs. The catheter will be stitched into place. Prime both lumens where appropriate. In some cases, warming of the contralateral leg may cause reflex vasodilation and increased perfusion in the compromised extremity. NeoMed Umbilical Vein Catheters, Artery Catheters, & Umbilical Vessel Catheters for sale online. If perfusion to the limb does not immediately improve with withdrawal of the catheter, the infant should be evaluated for possible severe thrombotic complications. 17-6). Finally, a neonate with HTN as a result of an aneurysm of the abdominal aorta has been reported (Kim et al., 2001); this fortunately rare condition may present with intractable congestive heart failure. Umbilical artery cannulation Before beginning the procedure, determine the insertion depth of the catheter as outlined previously (see Technical Considerations). Never leave the catheter open to atmospheric pressure. Infiltration may cause: Sloughing of deep layers of skin that may require skin grafting, Subcutaneous tissue calcification due to infiltration of calcium-containing IV solutions, Marc A. Raslich MD, in Pediatric Clinical Advisor (Second Edition), 2007, Neonatal history (especially umbilical artery catheterization), Medical history: renal disease (e.g., glomerulonephritis, polycystic kidneys, Henoch‐Schönlein purpura), systemic lupus erythematosus, urinary tract infections, renal trauma, diabetes mellitus, cardiac surgery, Family history: hypertension, atherosclerosis, preeclampsia, toxemia, renal disease, tumors (i.e., risk for essential hypertension and inherited renal or endocrine diseases), Review of systems: abdominal pain, dysuria, hematuria, frequency, nocturia, enuresis (may suggest underlying renal disease or infection); joint pains or swelling, facial or peripheral edema (nephrosis or nephritis); weight loss, failure to gain weight, flushing, sweating, fevers, palpitations (e.g., pheochromocytoma); muscle cramps, weakness, constipation (e.g., hypokalemia, hyperaldosteronism); age of menarche, sexual development (e.g., hydroxylase deficiency); ingestion of prescription, over‐the‐counter, or illicit drugs, Gerald M. Fenichel, in Neonatal Neurology (Fourth Edition), 2007. The placement of a catheter tip was defined as high when it was located in the descending aorta above the diaphragm and low when it was placed in the descending aorta above the bifurcation but below the renal arteries. Do not allow topical antiseptic to pool under the infant, allow to dry for 3 minutes and then drape the Studies using ultrasound report an incidence of umbilical artery–related thromboembolism from 14% to 35%, whereas studies using angiography document incidences up to 64%. A sterilized umbilical catheterization tray with the necessary instruments and drapes is available in the nursery. Autopsy studies have shown an incidence of UA-related thromboembolism between 9% and 28%, although major clinical symptoms of UA-related thromboembolism occur in 1%–3% of infants (Andrew et al., 2001). Supporting the stump is usually necessary. Catheterization of Umbilical Vein The umbilical cord stump and the surrounding abdomen are sterilized with a bactericidal solution. By continuing you agree to the use of cookies. Delayed presentations are common even weeks after an umbilical catheter. After insertion ascertain from NS-ANP/Medical staff which catheter is a UAC and UVC and label clearly. Studies indicate that umbilical artery catheters in the first 5 days are not associated with a high risk of thrombosis, although animal evidence suggests that even short-term umbilical arterial catheter use is associated with histological evidence of aortic thrombi and neointimal proliferation of the vascular wall that may not be clinically evident.40,41. Avoid sites beyond hairline. One of the most concerning side effects of umbilical artery catheters is the effect of blood sampling on cerebral blood flow. Acute and sometimes irreversible paraplegia may occur in newborns after umbilical artery catheterization. It allows vascular access for drug administration, exchange transfusion, or total parenteral feeding, especially in premature and low‐birth‐weight neonates. Before the procedure is begun, the correct depth of the umbilical artery catheter insertion should be estimated (see #6 below). Accurate prediction of the insertion length of the catheter is therefore paramount, as well as the confirmation of the position after insertion by chest X-ray or with ultrasound [9, 10]. The catheter and needle are advanced at an angle of approximately 30 degrees until the vessel is entered and a pulsatile blood return is encountered. The arteries are usually constricted, so that the lumens appear pin-point in size. In rare instances, an infant with an umbilical catheter will develop blanching of the foot or part of the leg. The umbilical artery begins to constrict after birth but may be cannulated up to the first few days of life. Objective Incorrectly positioned umbilical venous and arterial catheters (UVC and UAC) are associated with increased rates of complications in newborns. An echocardiographic study found intracardiac thrombi in 5% of infants with umbilical catheters.9 A more recent small study suggests that umbilical artery catheters in the first 5 days are not associated with a high risk of thrombosis.10. High umbilical artery catheters, placed at the T6 to T10 vertebral level, have been associated with a decreased incidence of clinical vascular complications without a statistically significant increase in any adverse effects (Barrington, 2000b). Other iodine-containing products (e.g., povidone iodine) can be used [146– 150]. The preferred location of the tip of the umbilical venous catheter is typically in the cephalad portion of the inferior vena cava or at the inferior vena caval–right atrial junction. Check for blood return, pulse waveform, and adequacy of distal circulation. Steven M. Donn, Barbara S. Steffes, in Manual of Neonatal Respiratory Care (Second Edition), 2006, Need for invasive blood pressure monitoring. Umbili-Cath™ is an umbilical vessel catheter (UVC) specially designed for ease of insertion, patient safety, and comfort during neonatal vascular access. Confirm position. A Cochrane review suggests that there is inadequate data to recommend either for or against routine antibiotic use in infants with umbilical catheters in place.15, Some centers avoid feeding infants with an umbilical artery catheter in place because of a theoretical concern that the catheter may interfere with mesenteric blood flow. The umbilical artery can be used for arterial access during the first 5-7 days of life [rarely beyond 7-10 days.] This is important to prevent clinical burns, especially in very small infants. Low—Insert 4 to 6 cm to achieve blood return if using for resuscitation or exchange transfusion. A recent study evaluating practice in United States intensive care nurseries (US NICUs) revealed that 79% of respondents prescribe small-volume enteral feeds in infants with umbilical catheters, and that over 50% prescribe larger enteral feedings.16 There are studies evaluating blood flow with umbilical arterial catheters in place, including a recent study specifically measuring superior mesenteric artery flow, showing no impact on either mesenteric flow or blood flow velocity when feeding with an umbilical catheter in place.17,18. Ben O’Neill Donovan, ... Bradley P. Kropp, in Pediatric Urology, 2010. However, as with all central catheters, meticulous care must be taken to maintain sterility during catheter insertion, and during subsequent withdrawal of blood from the catheter. An umbilical catheter with a single end hole may be used for the catheterization of either umbilical artery or vein. With proper care, the catheter need not be changed for the duration of its use. The reviewers concluded that high catheter position causes fewer clinically obvious ischemic complications. Studies using ultrasound report an incidence of UA-related thromboembolism ranging from 14% to 35%, whereas studies using angiography document incidences up to 64%. Halima Saadia Janjua, Donald L. Batisky, in Avery's Diseases of the Newborn (Ninth Edition), 2012. Prior to cannulation, the insertion site should be cleaned with an iodine or chlorhexidine solution. Procedure of Insertion of Umbilical Vein Catheter An umbilical venous catheter generally passes directly superiorly and remains relatively anterior in the abdomen. Tie a piece of umbilical tape around the base of the umbilical cord tightly enough to minimize blood loss but loosely enough so that the catheter can be passed easily through the vessel. Complications related to umbilical arterial catheters include vascular compromise, complications related to malposition, infection, bleeding, and catheter-related accidents (accidental disconnection, rupture, etc.). When noninvasive blood pressure monitoring is adequate. Trauma at the time of insertion of umbilical artery catheter by endothelial injury is postulated to be the cause of aortic thrombus formation which then leads to thrombosis of one or both renal arteries (Box 88-1). Surgical therapy in the chronic setting and in cases of subtotal occlusions may require an aortorenal bypass. It analyzed 11 randomized clinical trials and one study using alternate assignments to compare the incidence of morbidity and mortality for high versus low catheter tip placement. If only one umbilical catheter is to be removed, a nurse may remove the catheter if they have been stitched in separately. The single, large, thin walled oval vein can readily be distinguished from the two smaller, thick-walled round arteries (see diagram). Note color of blood obtained from vessel. Although this is a common practice, a study in normal infants without vasospasm showed that local warming has no effect on peripheral blood flow to the contralateral heel.11 Regardless of whether there is any value in warming the contralateral foot, the compromised leg should not be warmed because of the risk that this might increase the metabolic rate of the warmed tissues, leading to increased hypoxic tissue injury. Once the catheter is in place, it should be taped securely and connected to an infusion of heparinized saline with a T-connector and a three-way stopcock. The catheter will be inserted into the artery or vein of the stump. This resistance can usually be overcome by application of. In general, umbilical venous catheters are 5 Fr. The catheters are inserted by the pediatrician without imaging guidance, and given the small size of infants (especially those requiring umbilical catheters), a small variation in length of catheter can result in significant malpositioning (too long). The radial artery is usually most easily cannulated at the point of maximal pulsation over the distal portion of the radius, proximal to the superficial palmar branch of the artery. To provide partial or total fluids and/or nutrition when gastrointestinal nutrition is not possible. University of Iowa Stead Family Children’s Hospital is part of University of Iowa Hospitals & Clinics. If the umbilical venous catheter is advanced too far along its intended course, the tip may end up in a number of locatio… A rule-of-thumb is shoulder-to-umbilicus distance + 2 … Inadequate line clearing prior to sampling may result in spurious laboratory results. Estimating umbilical catheter insertion depth in newborns using weight or body measurement: a randomised trial. The incidence of infection associated with umbilical artery catheters appears to be lower than the incidence of infections associated with central venous catheters. Sterile gowns and gloves should be worn, as well as a head cover and a mask. Catheter insertion depth is often estimated using body surface measurement. Visualize, palpate, and/or use transillumination to select vessel for cannulation. Flank pain, hematuria, and hypertension are frequent manifestations of acute renal artery occlusions with evolving renal infarction in these children. A major risk factor for renal arterial obstruction is umbilical artery catheterization. It may be required for sampling and monitoring. The needle is held stationary and the catheter is threaded into the artery. Arch Dis Child Fetal Neonatal Ed . If the entire hand flushes and fills with blood, then it is safe to proceed with cannulation. Remember that samples obtained from the UAC are postductal. We have found that in some cases where there is blood return but the catheter cannot be advanced, insertion of a small guidewire through the catheter into the vessel lumen will help guide the catheter into the vessel. The cause of the paraplegia is infarction of the spinal cord secondary to embolism in the artery of Adamkiewicz. Cerebral infarction has been reported following superficial temporal artery cannulation, and thus this vessel should not be used. Up-to-date information and resources regarding COVID-19 preparation and response, Abbreviations commonly used in the nursery, Percutaneous placement of central venous catheters, Technique for insertion of a pericardial tube, Technique for insertion of an endotracheal (ET) tube, Iowa Neonatology Handbook: Authors and contributing authors, Translations of the Iowa Neonatology Handbook. A catheter is a long, soft, hollow tube. This may cause hepatic necrosis. The cord is then cut horizontally 1 cm above the skin with a scalpel blade. Nevertheless, an attempted operative repair is justified, especially when treating a vascular injury to a solitary kidney or bilateral injuries.56 Endovascular interventions offer a less invasive means of treating select patients in this setting.10. Use umbilical catheter (5.0 F (preterm); 8.0 F (term) for exchange transfusion in term infant); do not use feeding tube except as last resort. Revised John Dagle MD, PhD To sample blood from an umbilical catheter, withdraw 1 ml of blood into a sterile syringe, keeping the syringe perpendicular to the infant. The reported incidence of umbilical artery–related thromboembolism reflects, in large part, the diagnostic test chosen. It is important to avoid a tangential slice. Secure with tape bridge and (optional) sutures. As with all therapies, the potential risks of umbilical artery catheterization must be balanced against the potential advantages for each infant. Keep patency by infusing continuously but slowly. Iowa Neonatology Fellows Other significant risk factors are shock, coagulopathy, and congestive heart failure. Apply pressure to both the radial and ulnar arteries, then remove pressure from the hand and the artery that will not be cannulated. We recommend minimizing line “breaks” to reduce the risk of central line infection. Congenital vascular anomalies responsible for neonatal renovascular HTN include stenosis or hypoplasia of the renal artery and segmental intimal hyperplasia. A low-lying arterial catheter should have the tip at the third to fourth lumbar vertebra calculated at 2/3 the infant's umbilical-to-shoulder length. Similarly, if the dusky discoloration involves more of the foot or leg, the catheter should be removed. Observe both legs for evidence of blanching, cyanosis or mottling. Never infuse pressor agents through a UAC. In a high setting, the arterial catheter tip (UAC) should be positioned between the sixth and tenth thoracic vertebrae on chest x-ray. Tips if you meet resistance: Angle stump toward feet so catheter is directed toward the head; Try loosening the umbilical … When attempting scalp vein cannulation, shave area of head where IV needle is to be placed. For the purpose of an exchange transfusion, the catheter should be advanced only until there is a free flow of blood, but never more the 8 cm in the full term infant. 5-Fr catheters are used for arterial placement in larger infants. One should avoid cannulating the temporal artery because cerebral emboli have been reported in patients with temporal artery catheters.32,33. However, as with all central catheters, meticulous care must be taken to maintain sterility during catheter insertion and during subsequent withdrawal of blood from the catheter. Umbilical artery catheter insertion is a common procedure used in intensive care of neonates. Assess the depth that the catheter needs to be inserted from one of the following two methods: a) ({3 x baby’s weight in kg} + 9)/2 and add on cord stump length, (cm)17 Sterilise the cord and area around the cord with aqueous chlorhexidine. Galactosialidosis may result in intimal infiltration by sialyloligosaccharides and lead to hyperreninemic HTN (Nordborg et al., 1997). The catheter will be inserted into the artery or vein of the stump. At least two studies have suggested that the routine blood sampling alters cerebral hemodynamics and oxygenation.19,20 This effect seems to be less with lower-position catheters than with high-position catheters. As with all therapies, the potential risks of umbilical artery catheterization must be balanced against the potential advantages for each infant. Acute renal artery dissections and thromboses are most often a result of UAC in the neonate or iatrogenic events accompanying diagnostic or therapeutic catheterizations in older children. Evaluation in this case usually includes some combination of ultrasound or Doppler assessment, or even angiography. Umbilical artery catherisation is used to provide direct arterial access in the neonate. James C. Stanley, Jonathan L. Eliason, in Pediatric Surgery (Seventh Edition), 2012. Unfortunately, there is little literature available regarding the optimal approach to infants with severe vascular obstruction. We use cookies to help provide and enhance our service and tailor content and ads. The tape securing the catheter must allow for unobstructed view of all five digits because hypoperfusion, potentially leading to ischemic necrosis, is the major complication of peripheral arterial catheters. Infants with a birth weight of less than 1.5 kg will usually require a 3.5-Fr catheter for arterial catheterization. If the toes remain dusky, with poor capillary filling, the catheter should be removed. Although percutaneous cannulation of a peripheral artery is technically challenging, especially in infants weighing less than 1 kg, cannulation of the radial, ulnar, dorsalis pedis, or posterior tibial artery usually is possible. NEC (may be related to procedures such as exchange transfusion rather than to the catheter itself), When no longer needed or when other central venous access is achieved. If the toes remain dusky, with poor capillary filling, the catheter should be removed. Nephrectomy is undertaken when recovery of renal function is impossible. In some cases, warming of the contralateral leg may cause reflex vasodilation and increased perfusion in the compromised extremity.
