Which of the following complication is least likely during a 3-day period of monitoring with an arterial catheter?
|C||Infection at the catheter site|
a. Arterial monitoring is useful in the management of a severely ill or injured patient.
b. Continuous monitoring of cardiac output and stroke volume are needed but it is impractical to place a pulmonary artery catheter.
c. The radial artery is the most common site for arterial cannulation,
d. The most common complication is temporary occlusion of the artery.
e. Other serious complications are pseudoaneurysm, Pseudoaneurysm poses a risk for infection, sepsis, rupture and formation of an extracorporeal pseudoaneurysm .
f. Thrombosis is frequent with catheterization of the radial artery or other vessels of similar size.
g. Continuous heparin flow reduces this problem but increases the risk of wound hematoma.
h. Haemorrhage may occur if the catheter become disconnected.
i. When the femoral artery is used, haemorrhage into the pelvis may be significant, and it may escape detection.
j. Wound infection is unusual when careful wound care is maintained. Septicemia is rarely a problem unless the catheter is maintained for longer than 4 days.
