Sedation is essential for mechanically ventilated pediatric patients to ensure comfort, ventilator synchrony, and prevention of self-extubation. However, excessive sedation may prolong mechanical ventilation and ICU stay, while inadequate sedation may cause agitation and physiological distress. Continuous Sedation Infusion (CSI) and Daily Sedation Interruption (DSI) are two commonly used strategies. Limited data exist comparing their impact on comfort levels in pediatric patients.

This randomized controlled trial aims to compare comfort scores between continuous Midazolam infusion and daily sedation interruption in mechanically ventilated children aged 5-10 years diagnosed with pneumonia. Comfort will be assessed using the COMFORT-B Scale and Richmond Agitation-Sedation Scale (RASS) every 6 hours for 72 hours.

The study intends to determine which strategy better maintains optimal sedation and comfort in pediatric intensive care settings.

Inclusion Criteria:

Diagnosed with pneumonia

Requiring mechanical ventilation for at least 48 hours

Written informed consent obtained from parent or legal guardian

Exclusion Criteria:

Pre-existing neurological impairment (e.g., traumatic brain injury, stroke, cerebral palsy) that may interfere with comfort assessment

Presence of central nervous system symptoms affecting sedation evaluation

Contraindication to Midazolam (e.g., hypersensitivity, severe hypotension, significant hepatic dysfunction)

Receiving multiple sedative agents in addition to Midazolam

Refusal of parental or guardian consent
