Validity and reliability of the Niño Jesús Hospital procedural sedation scale under deep sedation-analgesia

Abstract Introduction The Nino Jesus Hospital procedural sedation scale (Madrid) (NJHPSS) has not been validated. Patients and methods A prospective analytical study was conducted in 2 hospitals on patients ≥6 months undergoing invasive procedures using sedation-analgesia with propofol or midazolam and fentanyl. All were monitored using the bispectral index (BIS). Videos were made of each procedure, which were then edited and randomised. A total of 150 videos were rated by four observers using the NJHPSS, the University of Michigan sedation scale (UMSS), and the Ramsay Scale (RS). These observers were blinded to the BIS, and at the time of drug administration. To assess test-retest reliability, 50 of the initial 150 randomly selected videos were re-assessed. Results The study included a total of 65 patients. Construct validity was demonstrated by changes in scores after administering sedatives (p  Conclusions The NJHPSS is valid, reliable and applicable for sedation monitoring in invasive procedures under deep sedation-analgesia in paediatric patients. The NJHPSS has worse properties than the UMSS and the SR.
