Application effect of an improved hydro-colloid dressing sticking method in attenuates facial pressure injuries / 中国实用护理杂志

ABSTRACT

Objective:To investigate the effect of an improved hydro-colloid dressing sticking method on preventing protective equipment induced facial pressure injuries among medical staff through a prospective, single-arm trial.Methods:According to the size of the edge of N95 mask, four pieces of hydro-colloid dressing with a size of 2 cm×5 cm were cut, and the edges of the mask were tension-free stuck. This improved sticking method was applied to the nurses working in the isolation ward. The follow-up was continued for two weeks, skin condition was reported daily, and the occurrence of pressure ulcers was analyzed after two weeks of follow-up.Results:Twenty percent (4/20) of subjects experienced increase grades of nasal and twenty five percent (5/20) in cheek pressure ulcers during a two-week follow-up. The incidence of the increased stage of cheek pressure ulcer in normal/dry skin was higher than in oily skin. Stage 2 pressure ulcers occurred in only five percent (1/20) of subjects, and no subjects had stage 3 or higher stage pressure ulcers. The incidence of increased cheek pressure ulcer grade in patients with neutral / dry skin was (5/11), higher than 0 in patients with oily skin ( χ2 value was 5.378, P = 0.02). The stage of nasal pressure ulcer was positively correlated with the disappearance time of the indentation of protective equipment ( r value was 0.615, P=0.004). The rate of increase in nasal pressure sore grade was higher in subjects who required more than 120 minutes of indentation recovery time (2/8) than in subjects who required 30 to 60 minutes 1/5 ( χ2 value was 4.382, P<0.05) and 60-120 minutes 1/5 ( χ2 value was 6.472, P<0.05). Conclusions:This improved hydro-colloid dressing sticking method can effectively prevent pressure injuries related to wearing N95 masks for a long time. However, skin evaluation of medical staff should be done properly, moisture protection for normal/dry skin should be emphasized, and skin blood flow recovery after compression should be strengthened. This method can reduce the risk of infection of medical staff, and it is worthy of clinical application.
