ABSTRACT

Introduction: Endotracheal suctioning (ES) is the most frequently performed invasive procedure in a cardiac surgical ICU. It is performed for aspiration of bronchial secretions from the airways of an intubated patient thereby maintaining airway patency and adequate ventilation and oxygenation. Two methods of ES are currently in practice - Open Endotracheal Suctioning technique (OES) and Closed Endotracheal Suctioning technique (CES). Aim: Aim of the research was to study the effect of Open and Closed endotracheal suctioning on the selected ABG values and Cardiorespiratory parameters. Methods & Materials: The design adopted for this study was experimental pretest post-test control group design. 30 samples who met the inclusion criteria were randomly allocated to experiment (CES) and control group (OES) using Sequentially Numbered Opaque Sealed Envelopes (SNOSE). ES was performed two hours after receiving the patient from operation theatre. The ABG values and cardiorespiratory parameters were recorded in the observation sheet immediately before the procedure and post procedure at 1 minute, 5 minutes and 15 minutes. Results: Subjects of both the study groups were homogenous with respect to the selected sample characteristics. Heart rate increased above baseline in both the groups, however the increase was statistically highly significant (p=0.002) in the OES. SBP significantly increased (p=0.03) post procedure in the OES group. SaO2 displayed significant difference with p=0.02 at 5 minutes after procedure in the CES. Conclusion: The findings of the study highlight that ABG variations and cardiorespiratory disturbances in the CES technique were less than those of the open technique.Therefore, to eliminate the unwanted effects of endotracheal suctioning on the ABG and cardiorespiratory parameters and to enhance the quality of nursing care and optimise patient outcome, the CES technique is recommended.
