Comparing The Effectiveness of Tracing Image and Coloring for Kids-Book With Two Active Distractions on Pain and Fear in Children During Venipuncture: A Randomized Controlled Trial

Venipuncture, a frequently performed needle-related procedure, is one of the foremost frightening experiences, and a typical source of moderate to severe pain for pediatric patients. Approximately 83% of young children aged 2.5-6 years, 51% of youngsters aged 7-12 years, and 28% of adolescents (aged more than 12 years) who underwent venipuncture stated high levels of distress during the painful procedure. However, < 10% of venipuncture performing are given pain management.

To relieve pain, fear, and anxiety in children undergoing venipuncture or venous cannulation, both pharmacological and non-pharmacological approaches are used to help control pediatric patients' discomfort. Pain management includes pharmacologic and non-pharmacologic approaches. The most commonly used pharmacological approach to decrease medical procedure-related pain is the application of topical anesthetic creams. Non-pharmacological methods include distraction actions like blowing bubbles, reading, or playing a game.

Balloon inflation causes a reduction in venous return with increased intrathoracic pressure. It has been speculated that this increase in pressure induces baroreceptor activation with contraction of the pulmonary vessels and that the activation of cardiopulmonary and sinoaortic baroreceptor reflex arcs has an antinociceptive effect, resulting in pain relief.

Coughing increases intrathoracic pressure and stimulation to the autonomic nervous system, causing an increase in heart rate and blood pressure, a higher level of pressure in the subarachnoid space, and baroreceptor activation. The increase in pressure in the subarachnoid space activates the segmental pain inhibiting pathways; thus, the increase in blood pressure and baroreceptor activation appears to be efficacious in reducing the perception of pain.
