Procedural moderate sedation with ketamine in pediatric critical care unit

Establishing the first ever pediatric procedural sedation clinic in a low-income country: Assessment of the safety and efficacy

BACKGROUND

Pediatric sedation clinics are rare in low-income countries. Our aim is to describe the establishment of the first-ever pediatric sedation clinic in Ethiopia and provide an assessment of its safety and efficacy over the 5 years since its establishment.

METHODS

A multi-phase approach was undertaken. In the first phase, we analyzed barriers to procedural pain management through repeated focus group discussions with stakeholders. Subsequently, we conducted a modified sedation provider course from the Society for Pediatric Sedation (SPS) with pre and post-training testing to document course effectiveness. Finally, we developed a procedural sedation clinic at Tikur Anbessa Specialized Hospital. In the second phase, we prospectively collected outcome data over a 5-year period from patients receiving procedural sedation at the clinic. This included assessing the efficacy of sedation and documenting any adverse events that occurred during the procedures.

RESULT

One hundred three providers completed the procedural sedation course. There was a 13.4% improvement in knowledge between baseline and post-course testing. A total of 2,820 patients underwent procedural sedation over the 5-year period from 2016 through 2021, and data selected from 475 (16.8%) patients were analyzed. The most common procedure performed was bone marrow aspiration/biopsy in 384 subjects (80.8%). The most common procedural sedation used was the combination of ketamine and propofol in 60.6%. The mean pain score during the procedure was 0.28/10, which was significantly lower than the pre-procedural pain score (p-value < 0.001). A total of 9 (1.9%) patients had adverse events and there was no mortality.

CONCLUSION

Based on our experience, development of a safe and effective sedation clinic is possible in resource-limited settings as evidenced by low procedural pain scores, and low adverse events rates. Provider training based on a modification of the SPS course improved overall procedural sedation knowledge.

Sedative and Analgesic Drug Rotation Protocol in Critically Ill Children With Prolonged Sedation: Evaluation of Implementation and Efficacy to Reduce Withdrawal Syndrome

OBJECTIVES

The first aim of this study was to assess the implementation of a sedative and analgesic drug rotation protocol in a PICU. The second aim was to analyze the incidence of withdrawal syndrome, drug doses, and time of sedative or analgesic drug infusion in children after the implementation of the new protocol.

DESIGN

Prospective observational study.

SETTING

PICU of a tertiary care hospital between June 2012 and June 2016.

PATIENTS

All patients between 1 month and 16 years old admitted to the PICU who received continuous IV infusion of sedative or analgesic drugs for more than 4 days were included in the study.

INTERVENTIONS

A sedative and analgesic drug rotation protocol was designed. The level of sedation, analgesia, and withdrawal syndrome were monitored with validated scales. The relationship between compliance with the protocol and the incidence of withdrawal syndrome was studied.

MEASUREMENTS AND MAIN RESULTS

One-hundred pediatric patients were included in the study. The protocol was followed properly in 35% of patients. Sixty-seven percent of the overall cohort presented with withdrawal syndrome. There was a lower incidence rate of withdrawal syndrome (34.3% vs 84.6%; p < 0.001), shorter PICU length of stay (median 16 vs 25 d; p = 0.003), less time of opioid infusion (median 5 vs 7 d for fentanyl; p = 0.004), benzodiazepines (median 5 vs 9 d; p = 0.001), and propofol (median 4 vs 8 d; p = 0.001) in the cohort of children in which the protocol was followed correctly.

CONCLUSIONS

Our results show that compliance with the drug rotation protocol in critically ill children requiring prolonged sedation may reduce the appearance of withdrawal syndrome without increasing the risk of adverse effects. Furthermore, it may reduce the time of continuous IV infusions for most sedative and analgesic drugs and the length of stay in PICU.
