Randomized Controlled Trial Observational StudyAcute and long-term dysphagia in critically ill patients with severe sepsis: results of a prospective controlled observational study.
Dysphagia is a major risk factor for morbidity and mortality in critically ill patients treated in intensive care units (ICUs). Structured otorhinolaryngological data on dysphagia in ICU survivors with severe sepsis are missing. In a prospective study, 30 ICU patients with severe sepsis and thirty without sepsis as control group were examined using bedside fiberoptic endoscopic evaluation of swallowing after 14 days in the ICU (T1) and 4 months after onset of critical illness (T2). ⋯ Multivariate analysis revealed tracheostomy at T1 as independent risk factor for severe dysphagia at T2 (p = 0.030). Severe sepsis appears to be a relevant risk factor for long-term dysphagia. An otorhinolaryngological evaluation of dysphagia at ICU discharge is mandatory for survivors of severe critical illness to plan specific swallowing rehabilitation programs.

Effects of the depth of anesthesia on distortion product otoacoustic emissions.
To analyze the effects of the depth of anesthesia on inner ear function measured with distortion product otoacoustic emissions (DPOAEs) at 2f 1 - f 2. Thirty patients who underwent tonsillectomy under general anesthesia (GA) were included. Patients were assigned randomly to one of two groups: group 1 (n = 15) received propofol, group 2 (n = 15) sevoflurane as anesthetic agent. ⋯ While overall there were different courses between these two groups in the 2 kHz DPOAE level, in the post hoc analysis only a tendency in the change from baseline to T 4 could be observed (p = 0.082). These results indicate that while the amplitudes of certain DPOAEs were influenced by GA, the depth of anesthesia had no effect on this measure of cochlear function in clinical routine. Therefore, DPOAE measurements in sedation and during GA are useful but the effect of anesthetic agents on DPOAE levels needs to be taken into account when analyzing the test.
