Further, it drives the healthcare systems under a severe financial burden. Preventing postoperative pneumonia is an incredibly challenging issue for clinicians. Since immunosuppression therapy, the patients who had kidney transplants are more vulnerable to postoperative infections. There is no data in the scientific literature focusing on the effects of preoperative oral care with chlorhexidine antiseptic solutions on postoperative pneumonia in kidney transplantation surgery cases. In the present research, we studied this topic. Methods: A prospective, randomized clinical trial was conducted at our institution between August 2020 and August 2022. Group A: Received 0.12 % chlorhexidine oral rinse preoperatively; Group B: Not received 0.12 % chlorhexidine oral rinse preoperatively. We analyzed the differences between the two trial groups using a chi-square or t-test. The Mann-Whitney U test was used for the categorical data. Results: Nine patients (17.6 %) were diagnosed with postoperative pneumonia in Group A and fourteen (25.9 %) in Group B (p < 0.05). Hospitalization time of Group B was prolonged (p < 0.05). In multivariate analysis, significant risk factors associated with postoperative pneumonia were advanced age, diabetes mellitus, smoking, delayed graft function and not gargling with 0.12 % chlorhexidine (p < 0.05). Conclusions: To reduce postoperative pneumonia risk in patients undergoing kidney transplantation surgery, an oral health protocol including 0.12 % chlorhexidine mouth rinse seems beneficial. © 2024 Royal College of Surgeons of Edinburgh (Scottish charity number SC005317) and Royal College of Surgeons in Irelandeninfo:eu-repo/semantics/closedAccess[No Keyword Available]ArticleQ1
