Description
Summary:To evaluate the effects of single-dose chlorhexidine oral care on bacterial colonisation and halitosis in patients undergoing elective surgery. We conducted a two-arm parallel, single-blinded, randomised controlled trial. The intervention group (n = 102) received preoperative oral care with 0.12% chlorhexidine gluconate, and the control group (n = 105) received standard care. The data of the microbiological cultures between the groups were compared at the time of tracheal intubation, at extubation and 30 min after surgery. The presence of halitosis was measured using a survey questionnaire administered to the anaesthesia nurses assigned to the patients. At baseline, no significant differences were found between the intervention and control groups for bacterial colonisation or halitosis. After the intervention, there was no significant difference in microbiological culture, including gram-positive, gram-negative bacilli and cocci results, between the two groups (p > 0.05). The presence of halitosis in the intervention group was significantly lower than in the control group during intubation (p
