Outcome of Vascular Complications After Arterial Punctures

Outcome of vascular Complications After Arterial PuncturesIntroduction -Arterial catheterizations argon used routinely for continuous haemodynamic observe in the operating room and also in critically ill patients (1). It provides easy and appropriate access for several(prenominal) blood samplings and blood gas analysis (2) and has frequently been found to be a safe procedure, with a few severe complications (3,4). Percutaneous arterial crowd outnulation is used widely in the clinical anxiety of critically ill adults second in frequency to intravenous cannulation(5). Common sites of percutaneous needle pierce include the radiate tire, femoral, brachial, dorsalispedis, or axillary arteria. There is no evidence that any site is superior to the former(a)s. However, the radial-ply tire arterial blood vessel is used most frequently due to its easy palpability, low complication rates, location and patients comfortability than the other sites. Patients undergoing radial or dorsalispe dis arterial blood vessel puncture should have the collateral flow to those vessels evaluated prior to puncture, to avoid the gamble of ischemic complications (6, 7). Each arterial catheterization site is associated with a unique set of potential complications. Radial artery interjection is associated with peripheral neuropathy, femoral artery insertion with retroperitoneal haematoma, axillary artery insertion with brachial plexopathy, and brachial artery insertion with injury to the median nerve(8). Although many sites sh atomic number 18 the same possible complications (eg, bleeding), the frequency of these complications varies among the unalike insertion sites. The most common complications associated with radial artery catheterization are occlusion (2 to 35 percent) and hematoma (up to 15 percent) (9). Permanent injury usually results from either complication. Frequent temporary occlusion of artery has been identified as one of the main complications of radial arterial cannu lation(10, 11).Arterial complications have serious ischemic damage to the hand after radial artery cannulation which lead to necrosis and amputation of fingers or the whole hand. (12). Femoral artery is the some other commonest site of arterial cannulation in intensive care units (13).The femoral artery is usually pet than the radial artery because the it is usually palpable even in hypotensive shock patients and is the only procurable route for haemodynamic monitoring(14). The incidence of related complications in the femoral artery is much lower than that in the radial artery and can be recognized easily because of the larger vessel diameter (15). Chances of sepsis is more in femoral artery cannulation because of the proximality of perianal region(16). The most common complication associated with femoral artery catheterization is hematoma (6%), which can be larger and difficult to detect if extends to the retroperitoneum(17). The third most dangerous site of arterial cannulatio n is axillary artery and it is preferred to be uncannulated because of its close proximity to carotid artery and whitethorn compromise cerebral circulation (18). Axillary artery cannulation is technically difficult, although pulsation and pressure are hold even with peripheral vascular collapse where as femoral artery cannulation is less difficult, can be cannulated, even during profound hypotension (24). Arterial catheter infectionsof 10 -20% are complicated by local (eg, insertion site) infection, and 5 % by bacteremia or sepsis (11).It is generally known that arterial puncture related complications are common in ICU. The purpose of this prospective analysis was to evaluate the nature and outcome of vascular complications by-line arterial punctures in intensive care units of King Abdulaziz Medical City.Wendt M, Hachenberg Th, Lawin P, Vietor G.
