RESUMO
OBJECTIVE: To determine the results of the implementation of a protocol in an intensive care unit (ICU) referred to critically ill patients requiring a prolonged artificial airway. DESIGN: A prospective, observational cohort study was carried out. INTERVENTION: Management strategies were established on the airway by endotracheal intubation (ETI) or tracheostomy, and guidelines were developed for action in the decannulation process. SETTING: A polyvalent ICU. PATIENTS: We studied 169 patients subjected to mechanical ventilation (MV), 67 with ETI ≥ 10 days of MV and 102 with percutaneous (PT) or surgical tracheostomy (TQ). VARIABLES OF INTEREST: ICU and hospital stays, days of ETI and MV, mortality, tracheostomy, anatomical risk factors, surgical complications, and postoperative decannulation period. RESULTS: ETI versus tracheotomy involved fewer days of MV (17 vs. 30 days, p<0.001), a shorter ICU stay (20 vs. 35 days, p<0.001), and a shorter hospital stay (34 vs. 51 days, p<0.001).There were more TQ procedures in patients with risk factors (47% TP vs. 89% TQ, p<0.001). Intraoperative minor bleeding was the most common complication, being associated with TQ (31% vs. 11%, p = 0.03). TP was associated with a shorter cannulationperiod (25 days vs. 34 days, p<0.04). CONCLUSIONS: The protocol variants showed no differences in terms of complications and mortality, when orienting application to patients with similar characteristics.

INTRODUCTION: Wide studies and substantial controversies build on utilization of actual mobile phones and appearance of systemic disorders or even tumours, but there is no knowledge about an eventual involvement on early hearing loss. PATIENTS AND METHODS: In a group of three hundred and twenty-three healthy and normoacoustic volunteers who were usual costumers of mobile phones an audiometric evaluation was made at the beginnig of its use and three years later, inquiring about the periods of time per day and year employed on direct contacts with phone. A healthy and normoacoustic control group of non users was studied too. RESULTS: Cases carried out 24.3 +/- 8.2 active contacts, reaching 50.4 +/- 27.8 days of mobile phone employment in three years. Audiometric curve was similar in cases and controls at the beginning of the study. After this follow-up, cases showed an increase on hearing threshold between 1 and 5 dB HL more than controls in speech tones (p<0.001). Moreover, there was a trend to correlate time of phone use to hearing impairment, but this finding did not result statistically significative. CONCLUSIONS: Frequent management of mobile phones in a middle period of time allows to detect a mild hearing loss, but the cause of this disorder keeps unclear.
