The effect of open suctioning of artificial airway based on the comprehensive criteria for suctioning on the patients pulmonary volumes and capacities hospitalized in the intensive care units

Background: The problem of airway suction of patients in special sectors is routine of this procedure. Therefore, the aim of this study was to investigate the effect of artificial airway open air suction on the basis of comprehensive criteria for the need for suction on the pulmonary volumes and capacities of patients in intensive care units. Methods: A randomized clinical trial with pre and post-test design with control group was performed in patients with artificial airway and mechanical ventilation. Sixty patients were selected through simple sampling and randomly assigned to two groups. In the patient group, the patient was evaluated according to the comprehensive criteria of suction and suctioned by standard method. In the control group, standard suction was performed with routine criteria. Before and after suction, the pulmonary volumes and capacities of the samples were determined and pre and post-test data were analyzed by SPSS software. ( IRCT Code: IRCT2015061012257N2).Results: The difference in pulmonary parameters between the two groups after suction in 2 minutes was significant in Resistance, Compliance and MV, and was not significant in P mean, TV and RR. Furthermore, the difference between two groups was significant after 5 minutes. The difference in the parameters of the two groups in the three times before, 2 and 5 minutes after suction in TV, MV, and between 2 and 5 minutes after the intervention. Compliance was not significant. Differences in compilation were significant in comparison with the prior and the 2nd and 5th minutes, but not significant between 2 and 5 minutes later. Conclusion: Standard criteria for preventing airway suction complications and the stability of pulmonary volumes and capacities in ventilator patients are effective and important.
