Closed Aspiration on Hemodynamic Changes and Pain

Study Overview
=================
Brief Summary
-----------------
The study was planned to determine the effects of closed aspiration on arterial blood pressure, heart rate, respiratory rate, oxygen saturation level and pain in intensive care patients connected to mechanical ventilators. IThe effects of the closed aspiration system on hemodynamic parameters and pain will be determined and the results will be important in terms of the usability of the closed system in the clinical environment and raising awareness in nursing practices in order to create minimum complications for the patient.

Detailed Description
-----------------
The research iss carried out in a single group pretest posttest quasi-experimental design in order to determine the effects of closed aspiration on arterial blood pressure, heart rate, respiratory rate, oxygen saturation level and pain in intensive care unit patients with mechanical ventilation. The research is carried out in Anesthesiology and Reanimation Intensive Care Unit. The sample of the study is patients who was intubated, not sedated, systolic arterial blood pressure 110-140 mmHg, diastolic arterial blood pressure between 60-90 mmHg, heart rate between 60-100/min, respiratory rate between 12-20/min, oxygen with saturation level (SpO2) >86%. Data is collected from the hospital's electronic patient record system and observationally before and after the aspiration. Patient Description Form, Hemodynamic Status and Pain Monitoring Form, Behavioral Pain Scale is used to collect research data.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Closed aspiration group<br>Closed system aspiration is performed according to standard guidelines for patients. | Other: Closed system aspiration<br>* Aspiration catheter; it is part of the ventilator and the ventilator circuit. The catheter is stored in a protective sheath. Therefore, the catheter can be used repeatedly during the day.<br>|

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Hemodynamic status form 1 | This form was used to record the arterial blood pressure of the patients. | 1 minute after aspiration. | 
| Hemodynamic status form 1 | This form was used to record the respiratory rate of the patients. | 1 minute after aspiration. | 
| Hemodynamic status form 1 | This form was used to record the oxygen saturation of the patients. | 1 minute after aspiration. | 
| Hemodynamic status form 1 | This form was used to record the heart rate of the patients. | 1 minute after aspiration. | 
| Hemodynamic status form 2 | This form was used to record the arterial blood pressure of the patients | 5 minute after aspiration. | 
| Hemodynamic status form 2 | This form was used to record the heart rate of the patients. | 5 minute after aspiration. | 
| Hemodynamic status form 2 | This form was used to record the respiratory rate of the patients. | 5 minute after aspiration. | 
| Hemodynamic status form 2 | This form was used to record the oxygen saturation of the patients. | 5 minute after aspiration. | 
| Hemodynamic status form 3 | This form was used to record the hemodynamic parameters arterial blood pressure of the patients. | 30 minutes after aspiration. | 
| Hemodynamic status form 3 | This form was used to record the hemodynamic parameters heart rate of the patients. | 30 minutes after aspiration. | 
| Hemodynamic status form 3 | This form was used to record the hemodynamic parameters the respiratory rate of the patients. | 30 minutes after aspiration. | 
| Hemodynamic status form 3 | This form was used to record the hemodynamic parameters oxygen saturation of the patients. | 30 minutes after aspiration. | 
| Behavioral pain scale 1 | It consists of three items: facial expression, upper extremities, and compliance with the ventilator. For each item, there are four variables that include behavioral responses to pain. Each section is given a score between 1-4. The score obtained from the scale is between 3-12. Higher scores indicate increased pain intensity. | 1st after aspiration. | 
| Behavioral pain scale 2 | It consists of three items: facial expression, upper extremities, and compliance with the ventilator. For each item, there are four variables that include behavioral responses to pain. Each section is given a score between 1-4. The score obtained from the scale is between 3-12. Higher scores indicate increased pain intensity. | 5th minutes after aspiration. | 
| Behavioral pain scale 3 | It consists of three items: facial expression, upper extremities, and compliance with the ventilator. For each item, there are four variables that include behavioral responses to pain. Each section is given a score between 1-4. The score obtained from the scale is between 3-12. Higher scores indicate increased pain intensity. | 30th minutes after aspiration. |
