This randomized controlled trial aims to evaluate the effects of pranayama and pursed-lip breathing exercises on postoperative pain, anxiety, and vital signs in patients undergoing breast surgery. Postoperative pain and anxiety are common problems that can negatively affect recovery, physiological stability, and overall well-being. Non-pharmacological interventions such as breathing exercises may help reduce these adverse outcomes and support recovery. Participants will be randomly assigned to one of three groups: a pranayama breathing exercise group, a pursed-lip breathing exercise group, or a control group receiving routine postoperative care. Breathing exercises will be performed three times daily for five minutes. Outcomes including pain, anxiety, and vital signs will be measured at baseline (pretest), postoperative day 1, and postoperative day 2. The findings of this study are expected to provide evidence on the effectiveness of breathing exercises as supportive nursing interventions in the postoperative care of breast surgery patients.

This study is a randomized, controlled, pretest-posttest experimental trial designed to evaluate the effects of pranayama and pursed-lip breathing exercises on postoperative pain, anxiety, and vital signs in patients undergoing breast surgery. Breast surgery patients frequently experience postoperative pain, anxiety, and alterations in physiological parameters such as blood pressure, heart rate, respiratory rate, and oxygen saturation. Although pharmacological management is commonly used, non-pharmacological complementary interventions may enhance recovery and improve patient comfort. Breathing exercises are low-cost, non-invasive interventions that may activate the parasympathetic nervous system, reduce stress responses, and improve oxygenation. Participants will be recruited from the General Surgery Department of a tertiary hospital. Eligible patients aged 18 years and older who undergo elective radical mastectomy, modified radical mastectomy, or simple mastectomy will be included. After providing informed consent, participants will be randomly assigned using block randomization into one of three groups: Pranayama Breathing Group (Nadi Shodhana technique) Pursed-Lip Breathing Group Control Group (routine postoperative care) Intervention groups will receive breathing exercises starting at the 4th postoperative hour. Exercises will be performed three times daily for two consecutive days, each session lasting approximately five minutes. The pranayama group will perform alternate nostril breathing (Nadi Shodhana), while the pursed-lip group will perform controlled inhalation through the nose followed by prolonged exhalation through pursed lips. The control group will receive standard postoperative care without breathing exercises. Primary and secondary outcomes will be assessed at baseline and after interventions. Pain intensity will be measured using the Visual Analog Scale (VAS). Anxiety levels will be evaluated using the State Anxiety Inventory (STAI-S). Vital signs including systolic and diastolic blood pressure, heart rate, respiratory rate, and oxygen saturation (SpO₂) will be recorded using standard clinical monitoring devices. Data will be analyzed using appropriate statistical tests depending on distribution characteristics, including repeated measures ANOVA or non-parametric equivalents. The study aims to determine whether pranayama and pursed-lip breathing exercises significantly reduce postoperative pain and anxiety and improve physiological stability compared to routine care. This trial is expected to contribute evidence regarding the effectiveness of structured breathing exercises as supportive nursing interventions in postoperative breast surgery care.
