- W1511264712 abstract "Tracheostomy is a commonly used technique in intensive care units, but there are no uniform criteria governing the periodicity with which tracheal cannulas should be changed. The objective of our study was to evaluate if different cannula-change schedules modified microbiological contamination and reduced the pain and bleeding related with cannula changes. In a comparative study of two groups, a control group in which the cannula was change every 48 hours and an experimental group in which the cannula was changed every 5 days were studied. Demographic differences, tracheostomy technique, microbiological study of the cannula, bronchial aspirate and stoma, clinical signs of stomal infection and secretions, and chest radiography were compared in the two groups. With each cannula change, we evaluated bleeding, pain, type of ventilation, hemodynamic disturbances, airway obstruction, opening of a false airway, oxygen saturation before and after cannula change, and recovery time. The study included 29 patients and 97 cannulas. In a homogeneous sample, the patients in the experimental group had a normal chest radiograph for a significantly longer time (p = 0.005). The stomas of the experimental group produced significantly less seepage (p = 0.04) and pain (p = 0.004). When the tracheostomy technique was correlated with the stoma, surgical tracheostomy performed in the unit showed significantly more reddening (p < 0.004) and seeping (p < 0.001). We conclude that prolonging cannula changes to every 5 days did not increase the incidence of contamination and reduced the pain of tracheostomized patients." @default.
