Background: Peripheral intravenous access is a commonly performed technical
nursing procedure in hospital and is vital for patients with chemotherapy. Obtaining venous
access is the first step in patient care, it may be difficult and cause patient discomfort, and
pain that may cause delay in patient management. Design: To achieve the aim of the study, a
quasi-experimental research design was utilized. Purpose of the study: to determine the
effect of moist heat on vein's integrity and pain among patients receiving peripheral
intravenous chemotherapy. Setting: The Oncology Department of Menoufia University
Hospital. Subjects: A convenient sample of 100 adult patients of both sexes with
chemotherapy treatment were selected and divided alternatively into two equal groups: 50
patients for each group (study - control). Tools: Three tools were used for data collection:
Structural interview questionnaire, Vein Assessment Scale, and Pain Assessment Scale.
Results: There was a highly statistical significant improvement in vein assessment score
(visibility and palpability) (p < 0.000) and VAS score (p < 0.000) in study group compared to
control group after intervention Conclusions: moist heat were effective in improving vein
visualization and alleviating pain during cannulation in studied patients.
