“…In general, there was variability observed in nursing practices related to oral healthcare. Five studies reported that nurses often used oral care solutions (saline, chlorhexidine, hydrogen peroxide solution, sodium bicarbonate solution, and distilled water/tap water) for mouthwash [4,44,57,65,70]. Various studies reported the use of foam swabs/swabbing (61-91.9%) [44,61], moisturizers (53-98.9%) [44,55], cotton/gauze swabs (69.9-93,5%) [55,61], saline (20-82.7%) [61,70], chlorhexidine (12.2-97.8%) [54,57,61,70], hydrogen peroxide solution (31.8%) [61], sodium bicarbonate solution (20.8-75.6%) [61,70], distilled water/tap water (4.3-17.9%) [55,61,70], mouthwash (57.8-88.2%) [55,70], toothbrushes (17.8-70%) [44,70], suction toothbrushes (93.5%) [55], and manual toothbrushes (49.5%) [55] for oral care.…”
