Prolonged use of personal protective equipment can cause pressure injuries on the skin. The current study was conducted with the aim of investigating the effect of ChitoHeal gel on the nasal site on the prevention of N 95 masks that caused pressure injuries in nurses working in intensive care units. This is a randomised controlled clinical trial that was conducted in 2022. The study sample consisted of 92 nurses working in the intensive care units. A randomised block method was used to allocate the nurses to two equal groups of intervention and control. However, in the intervention group, ChitoHeal gel was applied on nurses' nose bridge. To perform this, the researcher referred to the department during the morning and evening shifts and applied the gel on nurses' nose bridge at the beginning of each shift. Then, the N95 mask was installed on the face by the nurse. Before and at the end of each work shift, the skin in both groups was assessed for any signs of pressure injuries. No significant differences were observed between the two intervention and control groups in terms of demographic variables. The frequency distribution of mask-caused pressure injuries on nurses' nose bridge in the two groups was analysed using the Chi-square test (Fisher's exact test). The results showed that after the intervention, it was 0 in the intervention group. However, 4 nurses (8.6%) in the control group developed pressure injuries, and this difference between the two groups was statistically significant (P > .05). The result of the current study showed that the use of ChitoHeal gel is effective in preventing N95 mask-related pressure injuries. Considering the cheapness and rational global availability of this gel, it seems that its use is an effective strategy in order to prevent N95 mask-related pressure injuries. Given the lack of studies in this regard, similar studies are strongly recommended to be conducted.
