Abstract Background Sedation is an integral part in the management of critical patients in the pediatric intensive care unit (PICU). Optimum sedation is when the child is asleep but easily arousable. The patient should be able to breathe synergistically with the ventilator and should tolerate or be compliant with other therapeutic procedures. Undersedation can make the children hypertensive, tachycardic, and agitated. Conversely, oversedation can cause increased tolerance and prolonged ventilation. Both undersedation and oversedation have negative impacts on patient outcomes such as prolonged mechanical ventilation and ICU stay and increased risk of contracting ventilator-associated pneumonia, thus contributing to significant morbidity and mortality. This study aims to assess sedation levels in ventilated children using RASS in the first 48hrs of ventilation and study their correlation with patient outcomes. Results Of the 111 children enrolled in the study, 2 were excluded because the sedation was discontinued before 48 h, and 9 were excluded because they were ventilated for more than 7 days. Majority of the children receiving ventilation in PICU were oversedated (40%). Adequately sedated children were observed to have significantly lesser duration of mechanical ventilation (p-value: 0.022) and PICU stay (p-value: 0.01). Undersedated children were noted to have significantly higher incidence of self extubation (p-value: < 0.001), reintubation (p-value: < 0.001), and higher requirement of restraints (p-value: < 0.001). Oversedated had a higher incidence of VAP and mortality (p-value: < 0.001). Conclusion The findings of this study highlight the importance of achieving adequate sedation in PICU which is associated with better outcomes with respect to duration of ventilation, PICU stay, hospital stay, and mortality. This study also reflects the impact of absence of sedation protocols and emphasizes the need for monitoring of sedation and having protocols to guide clinical practice in order to improve patient outcome.
