Interventions

  • Respiratory Physiotherapy — OTHER
    Respiratory physiotherapy includes breathing exercises, postural drainage, percussion, and vibration techniques aimed at improving pulmonary function, facilitating secretion clearance, and enhancing oxygenation in postoperative cardiac surgery patients.
  • Progressive Muscle Relaxation — OTHER
    Progressive muscle relaxation is a systematic technique involving sequential contraction and relaxation of muscle groups combined with controlled breathing, aimed at reducing anxiety, improving psychological well-being, and promoting physiological relaxation.
  • Routine Care — OTHER
    Standard postoperative care and routine cardiac rehabilitation without additional respiratory physiotherapy or progressive muscle relaxation exercises.

Study Details

This study aims to evaluate the effects of respiratory physiotherapy combined with progressive muscle relaxation exercises on dyspnea, anxiety, hemodynamic status, and delirium symptoms in patients after cardiac surgery. This randomized controlled trial will include 116 patients who will be randomly assigned to an intervention group or a control group. The intervention group will receive respiratory physiotherapy and progressive muscle relaxation exercises in addition to routine postoperative care for 30 minutes per day over three consecutive days, while the control group will receive routine care only. Outcome measures will include dyspnea assessed by the Modified Borg Scale, anxiety assessed by the State-Trait Anxiety Inventory, hemodynamic parameters obtained from vital signs, and delirium symptoms assessed using the Nursing Delirium Screening Scale. It is hypothesized that the combined intervention will reduce dyspnea and anxiety levels, improve hemodynamic stability, and decrease delirium symptoms. The findings are expected to contribute to improved postoperative recovery and reduced complication risks following cardiac surgery.

Arms

  • Active Comparator: Routine Care
    Participants in this group will receive routine postoperative care and standard cardiac rehabilitation without additional respiratory physiotherapy or progressive muscle relaxation exercises.
  • Experimental: Respiratory Physiotherapy + PMR
    Participants in this group will receive respiratory physiotherapy techniques, including breathing exercises, postural drainage, percussion, and vibration, combined with progressive muscle relaxation exercises in addition to routine postoperative care. The intervention will be applied for 30 minutes per day over three consecutive days following cardiac surgery.

Primary Outcome Measure

Dyspnea (Modified Borg Scale) [ Time Frame: Within the first 24 hours after cardiac surgery (pre-intervention) and immediately after the intervention (post-intervention, same day) ]
