Introduction: Endotracheal suctioning is a procedure that exposes the patient to critical changes in vital signs. New AARC guidelines have emphasized both the importance of correct identification when to perform the procedure, and the routine use of closed system.
Objective: To implement the new guidelines AARC using a sound detector for identifying the presence of secretions (TBA care ©) , closed suctioning circuit and analyze the performance of vital signs in a population of cardiac patients.
Methods: The study is observational. Were investigated 15 patients undergoing CABG, cardiac surgery ICU. Were continuously recorded the following vital signs HR, SBP, SBP * HR, ST various leads, SpO2, PEEP, RRV, TVC in four time windows, 5 minutes before the suctioning maneuver at the time of operation (time 0), 5 minutes from the same and 10 minutes later.
Results: Vital signs remain stable in the four steps investigated, with minor variations (percent change from baseline during the maneuver: HR +2.93% 5.66% PAS +, SpO2 - 0.13%). There were no ST segment changes. There is an increase in the cardiac work, but within 5 minutes from the execution of the maneuver. There were no arterial desaturation.
Conclusions: The observed changes in vital signs, albeit small, suggest to keep the maximum hemodynamic and respiratory monitoring. The use of technologies for the diagnosis associated with the closed system of broncoaspiration has prevented the onset of complications related to the maneuver.
