RESUMEN
OBJECTIVE: To describe the general characteristics of the patient and device use. To know retention balloon pressure (RBP) and related factors. To identify rate of leakage incidence, relocation and perineal damage due to the device (PSD) and related risk factors. MATERIAL AND METHODS: An analytical observational, cross-sectional study conducted in a polyvalent ICU from June-December 2010 was performed. The sample included Flexi-Seal(®) carriers. Variables evaluated were patient and device use characteristics, RBP, leakage and quantity, relocation and reason, PSD, sedoanalgesia infusion, neuromuscular block, patient position, Flexi-Seal type catheter, ventilatory mode (VM), intra-abdominal pressure (IAP), mean intrathoracic pressure (MITP), PEEP, Glasgow, color-aspect, fecal consistency and volume. Significance P<.05. RESULTS: Twenty-one patients were included, 52% male, aged 54±17 with 30 insertion episodes, Flexi-Seal-Signal(®) 33%, 10±8 days permanency, main indication 33% «diarrhea and injured skin¼," 30% device removal «intolerance and/or spontaneous expulsion¼. Median (Me) PGR =40; RI (61-19) cmH2O. Factors associated to higher PGR: SCI absence, prone-decubitus position, leakage, relocation, conventional Flexi-Seal(®), MV, lower PEEP and IMP, Color-aspect, higher MITP. Leakage, relocation and PSD incidence density 43, 30 and 2 cases/100 days of catheter, respectively. Leakage and relocation risk factors: higher PGR, Glasgow and fecal volume, lower MITP, MV, assisted-spontaneous mode OR 2.5 CI (1.6-3.8) and OR 1.7(1.1-2.7), absence SCI OR 3.3 (2.2-5.1) and OR 2.4(1.5-3.8), absence neuromuscular block OR 2.4 (1.4-3.9) and OR 1.8 (1.1-3.1), Flexi-Seal(®) conventional OR 2.7(1.7-4.1) and OR 2 (1.2-3.3), respectively. Leakage risk factors: color-aspect, supine position, lower IMP and PEEP. CONCLUSIONS: Monitoring RBP may alert us about leakage presence and relocation need. Knowing associated risk factors to RBP, leakage and relocation would help to develop strategies to reduce their high incidence rate such as decreasing RBP by reducing inflated volume.
