La douche préopératoire chez les patients obèses : ce qu'en disent les patients et les soignants.

Introduction : At least one preoperative shower is recommended to avoid surgical site infection. Caregivers must explain the showering technique, help the patient if necessary, and assess skin cleanliness after showering.Context : Showering may be more difficult for obese patients because of inadequate equipment and difficulties moving, as well as insufficient explanation regarding the showering technique and an insufficient skin cleanliness assessment from caregivers.Objective : to assess whether patients and/or caregivers report difficulties in the preoperative shower process that could be linked to patient obesity. Methods : pilot qualitative survey with semi-structured interviews conducted with 9 obese surgery patients and 11 surgery caregivers.Results : Patients did not report feelings of discrimination. They described no problem with equipment, but declared having received little explanation on the showering technique and no visual skin cleanliness assessment. Caregivers reported equipment as inadequate, they stated having delivered detailed information, but found the skin cleanliness assessment difficult.Discussion : The lack of skin cleanliness assessment by caregivers after preoperative showering is new information. Limits : preliminary study with a small number of interviews and no non-obese patients.Conclusion : the subject warrants additional work with both quantitative and qualitative surveys to better understand the difficulties with preoperative showering.

Is the Risk of Wound Infection Related to Bilateral Internal Thoracic Artery Graft Potentiated by Age?

BACKGROUND: Older age and the use of bilateral internal thoracic artery (ITA) grafting are both considered risk factors for surgical wound infection (SWI) after coronary artery bypass grafting (CABG). The 2014 European Guidelines recommend that bilateral ITA grafting should be considered in patients aged younger than 70 years. Our aim was to investigate interaction between age and the number of ITA grafts. METHODS: All patients aged 18 years and older who had undergone CABG with at least 1 ITA at Rouen University Hospital between 2001 and 2012 were selected. Data regarding surgical procedure (single/bilateral ITA grafting) were extracted from the medical information system. SWI was identified from prospective surveillance of patients according to Centers for Disease Control and Prevention criteria. Independent factors associated with SWI were assessed by logistic regression, and an interaction test between age (≤69 or ≥70 years) and the number of ITA grafts was performed. RESULTS: SWI occurred in 71 of 2,726 patients (2.6%). Bilateral ITA grafting was associated with SWI (adjusted odds ratio [aOR], 2.55; 95% confidence interval, 1.51 to 4.30). After fitting an interaction term between age and number of ITA grafts, the aORs for SWI after bilateral ITA grafting substantially differed between patients aged 69 years and younger (aOR, 1.88; 95% confidence interval, 0.94 to 3.75) and 70 years and older (aOR, 3.52; 95% confidence interval, 1.69 to 7.33). However, this interaction failed to reach statistical significance (p = 0.2213), possibly because of insufficient statistical power (23.5%) despite the large sample size. CONCLUSIONS: Age 70 years and older compared with age 69 years and younger was associated with higher occurrence of SWI after bilateral ITA grafting, but this interaction was not statistically significant. Larger studies are needed to test this interaction.
