Effect of Oral Melatonin Versus Oral Midazolam as a Premedication in Children Undergoing Tonsillectomy

Preoperative anxiety is a common and significant concern in pediatric patients undergoing surgery. Anxiety is defined as a feeling of apprehension, fear, or uneasiness about an anticipated event, and in the surgical setting, it arises primarily from the fear of separation from parents, unfamiliar environments, painful stimuli, and the unknown nature of the procedure itself (Kain et al., 2006). Studies estimate that up to 60-70% of children experience substantial preoperative anxiety, with younger children, those with shy temperaments, and those undergoing repeated surgeries being at higher risk (Chow et al., 2016).

Causes and Contributing Factors Several factors contribute to heightened anxiety in children before surgery. These include developmental stage, previous hospitalizations, parental anxiety levels, lack of adequate preparation or information, and the presence of unfamiliar medical personnel (Fortier et al., 2010). Children aged between 1 and 5 years are especially vulnerable due to their limited coping mechanisms and fear of separation. A child's temperament, such as shyness or behavioral inhibition, also influences anxiety levels (Davidson et al., 2006).

Clinical Implications of Preoperative Anxiety Unmanaged preoperative anxiety has both immediate and long-term consequences. It can lead to increased distress during induction of anesthesia, higher requirements for anesthetic agents, postoperative pain, emergence delirium, and delayed recovery (Kain et al., 2004). Moreover, there is a correlation between preoperative anxiety and the development of postoperative maladaptive behaviors such as nightmares, bedwetting, aggression, and eating disturbances (Yuki and Daaboul, 2011) Assessment of Preoperative Anxiety Quantifying anxiety in children is essential for guiding intervention. Several validated tools are available, including the Modified Yale Preoperative Anxiety Scale (m-YPAS), which evaluates behaviors like activity level, vocalization, emotional expressivity, and use of parents. This scale is reliable in assessing anxiety levels during the preoperative period (Ramkisson, 2019).

Management Strategies Preoperative anxiety in children is a multifaceted problem that significantly affects surgical outcomes. Early identification and appropriate interventions, both behavioral and pharmacological, can reduce anxiety levels, improve compliance, and contribute to better perioperative experiences (Matthias and Samarasekera, 2012).

Management of preoperative anxiety in children includes both pharmacological and non-pharmacological methods. Non-drug approaches include parental presence during induction, behavioral interventions (e.g., distraction, play therapy, video games), and preoperative education. Pharmacological agents such as midazolam and melatonin are also widely used for anxiolysis. A multimodal approach is often the most effective (Agbayani et al., 2020).
