Routine Offered Protocol is not reliable for Thrombophlebitis Prevention

Abstract

<strong>Background:</strong> Intravenous catheterization is a routine technique in medical centers which can cause diverse problems such as thrombophlebitis. <br /><strong>Objective:</strong> This study aimed to resolve replacement scheduling and proper cannula diameter and position issues for intravenous catheters. <br /><strong>Methods:</strong> In this 2015 experimental cohort study, 232 hospitalized patients receiving medication intravenously were assessed for the occurrence of thrombophlebitis (TF). Involved TF factors such as age, gender, cannula size, site of cannula in hand veins, duration of usage, and underlying disease were evaluated in patient and healthy control groups. <br /><strong>Results: </strong>TF developed in 55 of 232 patients. The percentages of incidence were similar in men and women (30%). The patient mean age was lower than that of the control, but the difference was not significant. Average weight was significantly higher in the patient group than in the control group. The average duration of cannula in situ was significantly lower in patients than in the control group. The highest rate of TF occurred in the narrowest cannula usage and dorsal hand vein positions. The mean time of developing TF was lower than that indicated in CDC guidelines. Furthermore, 24 patients with TF (34%) had diabetes mellitus. <br /><strong>Conclusion:</strong> In the current study, the percentage of TF occurrence was higher in patients with weight increase, use of narrower cannulae, dorsal hand vein positions, and a history of diabetes. Furthermore, TF can develop within 72 hours. It was concluded that some patients may be more susceptible to TF and require more care. Accordingly, the CDC guidelines' offered scheduling for intravenous catheter replacement is not trustworthy.
