Effects of local heat application before intravenous catheter insertion in chemotherapy patients

Aims and objectives To characterise the effects of local heat application on the ease of subsequent intravenous catheter insertion. Background Intravenous catheter insertion is a challenging procedure for both nurses and chemotherapy patients. The local application of heat to the area before intravenous catheter insertion may decrease these difficulties by increasing venous distension and visibility. Design This study was an open label experimental study involving intervention and control groups. Methods Patients receiving chemotherapy were divided into intervention (n = 40) and control (n = 40) groups. For patients in the intervention group, a digital moist heating pad was applied to the arm prepared for catheter insertion for 10 minutes in addition to routine care. No additional preparation procedure beyond routine care was performed for control patients. Data were collected using a data collection form and evaluated using chi square, Fisher's exact chi square, Student's t, Mann–Whitney U, Wilcoxon and Pearson correlation tests. Results Local application of heat decreased patients' pain (p = 0·011), increased the rate of successful catheter placement at first attempt (p = 0·004), decreased the catheterisation procedure time (p = 0·001) and decreased nurse‐perceived difficulty during catheter placement (p = 0·001). Conclusions Local application of heat before the catheterisation procedure is suggested for patients receiving chemotherapy, particularly in cases where visibility of the veins is poor and intravenous catheter insertion is difficult. Relevance to clinical practice Local application of heat results in vasodilation, and thus intravenous catheter insertion becomes easier. Our findings have important implications for nurses who care for chemotherapy patients. The inclusion of local heat application before catheterisation as a preparation step is suitable to be implemented by nurses in other hospitals and clinics where chemotherapy is provided.
