Brief Summary

Physiotherapy is one of the most frequently used supportive treatments in intensive care units due to its positive effects on critically ill patients. Chest physiotherapy (GF), which constitutes the most effective part of the physiotherapy programs applied to intensive care patients under mechanical ventilation (MV) support, consists of a series of techniques aimed at clearing airway secretions, facilitating appropriate lung ventilation by increasing lung volume and respiratory muscle strength, and improving the respiratory system and gas exchange. . Of these techniques, manually applied percussion vibration and expiratory rib cage compression (EGCC) are some of the most commonly applied GF techniques in patients on MV support. This study was conducted to evaluate the effect of chest physiotherapy techniques applied before aspiration on vital signs, blood gas values and amount of secretion in patients on mechanical ventilation support.

Detailed Description

This study was carried out to determine the effect of chest physiotherapy techniques applied before aspiration on the vital signs, blood gas values and amount of secretion in patients on mechanical ventilation support.This randomized, controlled and experimental study was conducted between May 2021 and October 2022 in Tunceli State Hospital intensive care units with patients on mechanical ventilation support. The study was completed with a total of 78 patients, including the percussion vibration group (n=26), the expiratory rib cage compression group (n=26), and the control group (n=26). Data were collected with the "Patient Identification Form", "Vital Signs Recording Form", "Blood Gas Values Recording Form" and "Secretion Amount Recording Form". Two aspirations were performed in each of the three groups with an interval of three hours. Three hours after the first aspiration, chest physiotherapy techniques were applied to the two experimental groups, but not to the control group. A second aspiration was then performed. Vital signs and blood gases were measured before and after both aspiration procedures, and the amount of secretion collected during the two aspiration procedures was weighed.In the comparison between groups according to time; Statistically significant changes were found in heart rate during the first aspiration period, and diastolic blood pressure and respiratory rate during the second aspiration period (p<0.05). In the independent comparison between groups; statistically significant difference was found in diastolic blood pressure, respiratory rate and peripheral SpO2 values (p<0.05). In group comparisons; while the averages of secretion weight and amount did not show a significant change in all three groups (p>0.05), it was found that it tended to increase in the percussion-vibration and expiratory rib cage compression groups, while it tended to decrease in the control group.In this study, it was concluded that chest physiotherapy techniques had a beneficial effect on some vital signs in patients on mechanical ventilation support, did not make any difference in other parameters. Further studies are needed to determine the positive effects of these techniques on vital signs, blood gases and secretion.

Study Groups

expiratory rib cage compression group

Expiratory rib cage compression procedure phase; Three hours after the first aspiration data were obtained, before the second aspiration, expiratory rib cage compression was applied for 5 minutes in the right lateral and left lateral positions, applying to both lungs, with the most affected lung area first. Before and after the procedure, vital signs, blood gas parameters were measured and the amount of secretion collected during the aspiration process was weighed.

Group Type: EXPERIMENTAL

expiratory rib cage compression

Intervention Type: OTHER

Expiratory rib cage compression: The hands are placed on the lower third of the rib cage. During expiration, the end and sides of the patients' rib cage are gradually compressed with the hands.At the end of expiration, compression is released from the thorax to allow patients to take a free inspiration. After each compression, the patient is allowed to perform 3 breathing cycles.Expiratory rib cage compression is applied for 5 minutes.

percussion vibration group

Percussion, vibration process stage; Three hours after the first aspiration data were obtained, before the second aspiration, percussion and vibration were applied 3-5 times to each area, starting from the right and left lower lobes, in the right lateral and left lateral positions, with the most affected lung area being applied to both lungs first. Vital signs, blood gas parameters were measured before and after the procedure, and the amount of secretion collected during the aspiration process was weighed.

Group Type: EXPERIMENTAL

percussion vibration

Intervention Type: OTHER

Percussion :Percussion is performed 3-5 times on each area from a height of approximately 10 cm with the domed hand. . It starts from the right and left lower lobes and goes up.Vibration:The hand is firmly/strongly placed on the application area. The arm and shoulder are stretched and the fingers are gently vibrated or shaken gently. While the patient is exhaling, vibration is performed 3-5 times in each area, starting from the right and left lower lobes.

control group

Control group phase; In this group, vital signs, blood gases, and secretion amount were recorded at the same time as the experimental groups, without any intervention.

Group Type: NO_INTERVENTION

No interventions assigned to this group
