The Effect of Breathing Exercises and the Valsalva Maneuver on Pain Reduction During Peripheral Intravenous Catheterization: A Randomized Controlled Trial

One of the non-pharmacological methods used for pain reduction is breathing exercises. As a distraction technique, breathing exercises have been increasingly utilized to alleviate invasive pain experienced during blood collection and cannulation procedures. By enhancing lung ventilation, deep breathing maximizes oxygen intake, leading to relaxation in the patient. This state of relaxation contributes to a sense of comfort and reduces the perception of pain.

A review of the literature revealed only one study specifically evaluating the effectiveness of breathing exercises in reducing pain during PIVC insertion. Existing research has reported that breathing exercises have a positive impact on pain experienced during PIVC placement. In these studies, individuals were first positioned comfortably. They were then instructed to take a slow, deep breath through the nose, hold it briefly, and exhale slowly through the mouth. During inhalation, participants were guided to expand their abdomen and push the diaphragm downward, while during exhalation, they were asked to contract the abdominal muscles, draw the abdomen inward, and push the diaphragm upward. Additionally, individuals were instructed to silently count to four while inhaling, holding their breath, and exhaling. The breathing exercise began one minute before the procedure and continued throughout its duration.

Another non-pharmacological method used for pain reduction is the Valsalva maneuver, a well-known breathing technique. The Valsalva maneuver involves a forceful exhalation against a closed airway, stimulating the vagus nerve and causing physiological changes, particularly in heart rate and blood pressure. These physiological effects make the Valsalva maneuver a valuable diagnostic and therapeutic tool for terminating supraventricular tachycardia, assessing cardiac murmurs and left ventricular function, managing neuropathy, and controlling pain.

A review of the literature identified a few studies evaluating the effects of the Valsalva maneuver on pain, anxiety, and vital signs during PIVC insertion. The findings of these studies indicate that the Valsalva maneuver has a positive effect in reducing pain experienced during the procedure.
