Abstract

Wound cleansing is an essential procedure to decrease the likelihood of wound infection. This quasi-experimental research aimed to examine the effects of wound irrigation using a pressure-controlled technique on wound infection and satisfaction towards wound cleansing among persons with laceration wounds. The participants included 58 persons with laceration wounds receiving care at an emergency room. There were 29 participants each in the control group and the experimental group. The participants in both groups were matched by wound cause, wound size, wound location, age, history of diabetes mellitus, history of cancer, smoking, and receiving of antibiotics. The research instrument was the pressure-controlled wound irrigation equipment developed by Bussa et al. (2017). The data collection instruments were the Lacerated Wound Infection Evaluation Form developed by Bussa et al. (2017) and the Satisfaction Towards Wound Cleansing Evaluation Form developed by the researcher. The Satisfaction Towards Wound Cleansing Evaluation Form was evaluated for validity by five experts yielding an index of item-objective congruence between 0.80-1.00. It was checked for its test-retested reliability, yielding a Pearson’s correlation coefficient of 0.82. Data were analyzed using descriptive statistics, the Mann-Whitney U test, and the Fisher Exact Probability test. The results revealed that: 1. The wound infections among the experimental group were statistically significantly lower than those of the control group (p <.05). None of the participants in the control group had wound infection, while six participants in the experimental group (20.69%) had wound infection. 2. The satisfactions towards wound cleansing among the experimental group (mean = 4.97, S.D. = 0.19) were statistically significantly her than those of the control group (mean = 4.72, S.D.= 0.53) (p <.05). The results of this study reveal that wound irrigation using pressure-controlled technique can reduce wound infection and increase satisfaction towards wound cleansing among persons with a laceration wound.
