Our objective was to identify factors associated with the duration of mechanical ventilation (MV) postoperative to cardiac surgery and assess the association between duration of endotracheal intubation, length of stay in the Intensive Care Unit (ICU) and hospital. Longitudinal, retrospective study of medical records of 116 adults undergoing cardiac surgery from March 2012 to May 2013. ⋯ Associated with longer MV was the age (r = 0.5, p < 0.001), comorbidities (r = 0.344, p < 0.001), cardiopulmonary bypass time (r = 0.244, p = 0.008), duration of continuous sedation (r = 0.607, p < 0.001), sedative doses (r = 0.4, p < 0.001), time of vasoconstrictors and vasodilators (r = 0.711, p < 0.001, r = 0.368, p < 0.001), drainage of the 1st time (r = 0.201, p < 0.031), presence of drains (r = 0.445, p < 0.001), postoperative complications (r=0.524, p< 0.001) and hospital stay. Our data confirms that both preoperative, transoperative and postoperative variables prolong the VM and therefore the hospital stay.

Observational Study
[Stimulus-response time to invasive blood pressure alarms: implications for the safety of critical-care patients].
Observational, descriptive, exploratory, case study with the objective of measuring the stimulus-response time of the team to alarms monitoring invasive blood pressure (IBP) and analyzing the implications of this time for the safety of the patient From January to March 2013, 60 hours of structured observation were conducted with registration of the alarms activated by IBP monitors in an adult ICU at a military hospital in the city of Rio de Janeiro. 76 IBP alarms were recorded (1.26 alarms/hour), 21 of which (28%) were attended to and 55 (72%) considered as fatigued. The average response time to the alarms was 2 min. 45 sec. The deficit in human resource and physical layout were factors determining the delay in response to the alarms. ⋯ Fatigue. Patient safety. Intensive care.
