Какого размера должна быть канюля?
Peripheral devices are available in a range of gauge sizes and lengths. Many incorporate safety features for sharps injury prevention, and the use of a safety cannula is recommended (RCN, 2005). The smallest gauge and shortest length of cannula should be selected for the prescribed therapy (RCN, 2005). Emergency situations, such as trauma or haemorrhage, require short, large-bore cannulae, e.g. 14 g for rapid administration of fluids and blood (Scales 2008); hydration fluids and antibiotics can be delivered through much smaller cannulae, e.g. 20 g or 22 g. Smaller cannulae are less likely to cause mechanical phlebitis (irritation of the vein wall by the cannula) and are less likely to obstruct blood flow within the vein (Tagalakis et al, 2002). - Intravenous therapy: a guide to good practice

The review found no difference in catheter‐related bloodstream infection or phlebitis rates whether peripheral intravenous catheters are changed routinely every 72 to 96 hours or when clinically indicated. The consistency in these results, which now include a very large multi‐site study, indicate that healthcare organisations should adopt a clinically‐indicated replacement policy. This would provide significant cost savings and would also be welcomed by patients, who would be spared the unnecessary pain of routine re‐sites in the absence of clinical indications. Busy clinical staff would also reduce time spent on this intervention. To minimise peripheral catheter‐related complications, the insertion site should be inspected at each shift change and the catheter removed if signs of inflammation, infiltration, or blockage are present. - Clinically‐indicated replacement versus routine replacement of peripheral venous catheters.
