Background: The ideal treatment for patients who suffer from sacrococcygeal pilonidal sinus
disease (SPSD) should lead to a cure with a rapid recovery period allowing a return to normal daily
activities, with a low level of associated morbidity. Aim: To evaluate the effect of educational
guidelines on surgical nurses' knowledge and practice regarding phenolisation dressing technique for
patients with sacrococcygeal pilonidal sinus disease. Design: Quasi-experimental research design
was used in this study. Setting: The current study was conducted at the General Surgery
Departments at Mansoura University Hospital. Subjects: A convenient sample technique of a total
of 50 nursing staff working in the General Surgery Departments was recruited in the study. Three
tools were used for data collection; Tool (1): Nurses' demographic characteristics; Tool (2): Nurses'
knowledge about phenolisation dressing technique (pre/post), Tool (3): Nurses' practice about
phenolisation dressing technique (pre/post). Results: The study result revealed that more than half
of the studied nurses were between 20 to less than 30 years old and more than three fifths of the
studied nurses were female. More than two-fifths of the studied nurses have a diploma from
secondary nursing school. There was a highly statistically significant difference between the pre
educational guidelines and post-educational guidelines regarding nurses' knowledge and practices
about phenolisation dressing technique. There was a statistically significant positive correlation
between the total knowledge and total practice scores of the studied nurses regarding phenolisation
dressing technique for patients with sacrococcygeal pilonidal sinus disease. Conclusion:
Educational guidelines had a positive effect on improving surgical nurses' knowledge and practice
regarding phenolisation dressing technique for patients with sacrococcygeal pilonidal sinus disease.
Recommendations: Educational programs about the importance of phenolisation dressing technique
should be provided to nurses working in surgical units.
