The Effect of Closed System Suction on Pain

Endotracheal intubation and mechanical ventilation are life-saving practices in patients with respiratory failure, and aspiration of secretions is often required to maintain airway patency. Although tracheal aspiration is an unavoidable requirement to maintain airway patency, it can bring many undesirable conditions. In the presence of complications, the duration of hospital stay is also prolonged. In the literature, endotracheal aspiration is defined as a painful and uncomfortable method for patients. However, pain is an undesirable sensation that cannot be adapted. The most reliable source for pain assessment is the patient himself. However, verbal communication with patients in the ICU is quite difficult due to reasons such as the presence of endotracheal tube and tracheostomy, confusion, mechanical ventilation, and sedative drug use. Therefore, intensive care patients may not be able to express their pain verbally. In this case, patient behavior becomes important in pain assessment. Scales were developed for pain assessment of patients who could not express their pain. The "Behavioral Pain Scale" (DAS) was developed by Payen et al. For this purpose and made available to intensive care patients.

Patients who meet the inclusion criteria and agree to participate in the study when aspirating is required (Seeing pulmonary secretions in the endotracheal tube, tachypnea, tachycardia, hypertension, worsening of oxygen saturation and / or arterial blood gas, sawtooth pattern in the flow volume loop of the ventilator monitor and / or trachea Hearing of coarse breathing sounds, Ppeak inspiratory pressure increase in mechanical ventilator in volume-controlled mode, or tidal volume decrease in pressure-controlled mode, etc.) by a volunteer nurse, whether there is pain before, during and after aspiration, the severity and localization of the pain will be recorded by VAS and VAS. . The patient will be aspirated with the same aspiration technique in all patients by using a closed system aspiration catheter by the other volunteer nurse. Aspiration procedure will be applied to each patient according to the American association for respiratory care (AARC) aspiration guideline. The nurse evaluating the pain will record whether the patients have pain with DAS and VAS, the severity and localization of the pain

Endotracheal intubation and mechanical ventilation are life-saving practices in patients with respiratory failure, and aspiration of secretions is often required to maintain airway patency. Although tracheal aspiration is an unavoidable requirement to maintain airway patency, it can bring many undesirable conditions. In the presence of complications, the duration of hospital stay is also prolonged. In the literature, endotracheal aspiration is defined as a painful and uncomfortable method for patients. However, pain is an undesirable sensation that cannot be adapted.

It is thought that performing aspiration in accordance with the AARC guideline and listening to music during the procedure reduce the pain in edotracheal aspiration. The most reliable source for pain assessment is the patient himself. However, verbal communication with patients in the ICU is quite difficult due to reasons such as the presence of endotracheal tube and tracheostomy, confusion, mechanical ventilation, and sedative drug use. Therefore, intensive care patients may not be able to express their pain verbally. In this case, patient behavior becomes important in pain assessment. Scales were developed for pain assessment of patients who could not express their pain. The "Behavioral Pain Scale" (DAS) was developed by Payen et al. For this purpose and made available to intensive care patients. DAS consists of three parts, including facial expression, upper extremity movements, and compliance with mechanical ventilation, and a total of 12 items. Each section is given a score between 1 and 4. The lowest pain score obtained from the scale is 3 and the highest pain score is 12. (Appendix 1) Patients with an unconscious communication can be established with a sign or writing method instead of verbal communication with patients with tracheostomy or tracheal tube. These patients can describe their pain without words. Visual pain scales can be used for this purpose. Visual Pain Scale (VAS) is one of these scales. VAS was first used in the 1970s. The scale was defined by Selby et al. To evaluate the quality of life in patients with cancer in the 1980s. VAS has been used in many studies evaluating different parameters after the 1990s and has recently been used in the measurement of special conditions such as pain. The test has proven itself for a long time and is a accepted test in the world literature. Safe, easy to apply Is DAS an accurate pain descriptor for every application in intensive care unit?;. This question guides the study. This study was planned with the thought that the result may be misleading in applications such as eye care and aspiration that will trigger reflex movements in intensive care.

6-Research protocol, materials and methods: METHOD In this study, when alpha 0.05, = 0.10, 1-B 0.90 was taken, 32 patients were included in the study and the power of the test was found to be P = 0.9657.

Time of Research: Research 01.07. It will be applied in the Anesthesia and Reanimation Intensive Care Unit (EIB) of a university hospital between 2020 - 31.12.2020.

The Type and Purpose of the Study: This study was planned as a prospective observational study in order to examine whether conscious patients connected to mechanical ventilator in the Anesthesia Intensive Care Unit experience pain during the closed system aspiration procedure, and if pain is experienced, whether NAC is reliable in evaluating the pain occurring in endotracheal aspiration.

The Population and Sample of the Study: The population of the study was the sample of all patients who were treated in the Anesthesia and Reanimation Intensive Care unit of a university hospital between the research dates, and the patients who were connected to the ventilator who agreed to participate in the study and underwent endotracheal aspiration.

Research Application Patients who meet the inclusion criteria and agree to participate in the study when aspirating is required (Seeing pulmonary secretions in the endotracheal tube, tachypnea, tachycardia, hypertension, worsening of oxygen saturation and / or arterial blood gas, sawtooth pattern in the flow volume loop of the ventilator monitor and / or trachea Hearing of coarse breathing sounds, Ppeak inspiratory pressure increase in mechanical ventilator in volume-controlled mode, or tidal volume decrease in pressure-controlled mode, etc.) by a volunteer nurse, whether there is pain before, during and after aspiration, the severity and localization of the pain will be recorded by VAS and VAS. . The patient will be aspirated with the same aspiration technique in all patients by using a closed system aspiration catheter by the other volunteer nurse. Aspiration procedure will be applied to each patient according to the American association for respiratory care (AARC) aspiration guideline. The nurse evaluating the pain will record whether the patients have pain with DAS and VAS, the severity and localization of the pain.

Evaluation of the Data: The data obtained from the study are SPSS v.22 (Statistical Package for Social Sciences) package program will be used. When parametric test assumptions are fulfilled, repeated measures variance analysis will be used in the analysis of more than two measurements from a group, and Friedman test will be used when parametric test assumptions are not fulfilled. The level of error will be considered as 0.05.
