Observation on the effect of power PICC with two different external lengths in catheterization of patients with hematologic diseases / 中国实用护理杂志

ABSTRACT

Objective:To investigate the effect of power PICC with two different external lengths in patients with hematologic diseases.Methods:From August 2020 to August 2021, a retrospective analysis was conducted on 233 cases of hematologic diseases who received power PICC catheterization in Department of Hematology, the Nanfang Hospital of Southern Medical University, the patients were divided into 0-1 cm group (132 cases) and 2-4 cm group (101 cases) according to the external lengths after catheter insertion. The incidence of related complications and patient comfort at 24 hours, 72 hours, 7 days and 14 days after catheterization were compared between the two groups.Results:At 24 hours and 72 hours after catheterization, the incidence of bleeding at puncture point in 0-1 cm group was 14.39%(19/132) and 9.85%(13/132), in 2-4 cm group was 30.69%(31/101) and 32.67%(33/101), the difference was statistically significant ( χ2=9.02, 14.16, both P<0.05). The rate of redness and swelling of punture point at 7 days after catheterization was 9.09%(12/132) and 40.59%(41/101) in the two groups, with statistical significance ( χ2=32.32, P<0.05). The rates of slightly prolapse at 7 and 14 days after catheterization were 18.18% (24/132) and 18.94%(25/132) in 0-1 cm group, 59.41% (60/101) and 67.33%(68/101) in 2-4 cm group, the difference between the two groups was statistically significant ( χ2=42.18, 55.86, both P<0.05). In the observation of comfort at 14 days after catheterization, the comfort score of patients in the 0-1 cm group was significantly higher than that in the 2-4 cm group, and the difference between the two groups was statistically significant ( χ2=7.34, P<0.05). Conclusions:Patients with hematologic diseases can reduce the risk of bleeding and slightly prolapse, and improve the comfort of patients when the external lengths is 0-1 cm of power PICC, which is worthy of clinical application and promotion. The catheterizer should adopt accurate in appropriate measurement method to determine the best lengths of the catheters.
