Background:Intubated patients in Intensive Care Unit (ICU) are not able to take care of their mouth health, so they are at risk of bacterial colonization and dental plaques formation that can lead to systemic diseases such as pneumonia and gingivitis.Aims:In randomized, double-blind clinical study, the efficacy of natural herbal mouthwash containing Salvadora persica ethanol extract and Aloe vera gel was compared with chlorhexidine on gingival index (GI) of intubated patients in ICU.Materials and Methods:Seventy-six intubated patients (18–64 years old with mean age 40.35 ± 13.2) in ICU were admitted to this study. The patients were randomly divided into two groups: (1) Herbal mouthwash and (2) chlorhexidine solution. Before the intervention, the GIs was measured by modified GI device into two groups. The mouth was rinsed by mouthwashes every 2–3 h for 4 days. 2 h after the last intervention, GIs were determined.Results:Along with mechanical methods, herbal mouthwash in reducing GI was statistically significant than that of chlorhexidine (P < 0.05).Conclusion:The results of this study introduce a new botanical extract mouthwash with dominant healing effects on GI (1.5 ± 0.6) higher than that of synthetic mouthwash, chlorhexidine (2.31 ± 0.73).

Background:Patients in the intensive care unit (ICU) have impaired ocular protective mechanisms that lead to an increased risk of ocular surface diseases including exposure keratopathy (EK). This study was designed to evaluate the effect of normal saline (NS) on the incidence and severity of EK in critically ill patients.Materials and Methods:This single-blind randomized controlled trial was conducted on 50 patients admitted to ICUs. The participants were selected through purposive sampling. One eye of each patient, randomly was allocated to intervention group (standard care with NS) and the other eye to control group (standard care). In each patient, one eye (control group) randomly received standard care and the other eye (intervention group) received NS every 6 h in addition to standard care. The presence and severity of keratopathy was assessed daily until day 7 of hospitalization using fluorescein and an ophthalmoscope with cobalt blue filter. Chi-square test was used for statistical analysis in SPSS software.Results:Before the study ( first day) there were no statistically significant differences in the incidence and severity of EK between groups. Although, the incidence and severity of EK after the study (7th day) was higher in the intervention group compared to the control group, their differences were not statistically significant. Although, the incidence and severity of EK, from the 1st day until the 7th, increased within both groups, this increase was statistically significant only in the intervention (NS) group.Conclusions:The use of NS as eye care in patients hospitalized in ICUs can increase the incidence and severity of EK and is not recommended.
