“…Phlebitis is characterized by inflammation of the vein wall and can be accompanied by symptoms such as edema, pain, and erythema near the catheter insertion site or along the affected vein, sometimes progressing to palpable venous cord, intense redness, tenderness, and fever [7]. Factors affecting the incidence of phlebitis can be classified into individual factors, such as sex [8], age [9], underlying health conditions such as infectious or hypertensive disease and surgery [8], and caregiver residence [10]; chemical factors, such as the osmolality of the injected drug [11], number of medications [12], type of antibiotics [13], and rate and method of drug injection [14]; mechanical factors, such as catheter dwell time, which can cause friction due to intravascular movement of the catheter [15], catheter insertion site [15,16], and catheter size [12]; and infectious factors, such as hand hygiene of health professionals [17] and nurse’s skill in administering intravenous injection [18].…”
