Pediatric anesthesia & critical care

Monitoring anesthesia depth with patient state index during pediatric surgery

Paediatr AnaesthPublished Prospective observational study

Authors' conclusion

NonpEEG-guided anesthesia in children led to median patient state index levels at the low range of recommended unconsciousness values with frequent episodes of burst suppression. Patient state index levels were generally higher in children below 2 years.

Study context

Population
Children aged 1–18 years undergoing surgery longer than 60 min under GA conducted according to indirect evaluation of depthenrolled
Participants
111 children
Outcome
Median patient state index (PSI) and spectral edge frequency 95% (SEF95) values
Methodological detailsSedLine monitor with pediatric sensors; PSI recorded at predefined time points until discharge to ward
  • SedLine monitor with pediatric sensors; PSI recorded at predefined time points until discharge to ward

Right/left SEF95 at end of induction (Hz)
10 (6-14)/9 (5-14)
SEF95 in maintenance phase, both hemispheres (Hz)
