Palliative Care in the Pediatric Intensive Care Unit.

The purposes of this review are to describe differences between palliative care for adult patients and palliative care for pediatric patients, both generally and in the intensive care unit; to highlight ethical considerations for pediatric intensive care unit patients by using illustrative cases; and to examine the impact of these ethical considerations on decision-making for children and their families.

iciHHV-6 in a Patient With Multisystem Inflammatory Syndrome in Children.

Multisystem inflammatory syndrome in children (MIS-C) is a serious, sometimes life-threatening late complication of coronavirus disease 2019 (COVID-19) with multiorgan involvement and evidence of immune activation. The pathogenesis of MIS-C is not known, nor is the pathogenesis of the severe organ damage that is the hallmark of MIS-C. Human herpesvirus 6 (HHV-6), the virus responsible for roseola, is a ubiquitous herpesvirus that causes close to universal infection by the age of 3 years. HHV-6 remains latent for life and can be activated during inflammatory states, by other viruses, and by host cell apoptosis. HHV-6 has been associated with end-organ diseases, including hepatitis, carditis, and encephalitis. In addition, ∼1% of people have inherited chromosomally integrated human herpesvirus 6 (iciHHV-6), which is HHV-6 that has been integrated into chromosomal telomeric regions and is transmitted through the germ line. iciHHV-6 can be reactivated and has been associated with altered immune responses. We report here a case of MIS-C in which an initial high HHV-6 DNA polymerase chain reaction viral load assay prompted testing for iciHHV-6, which yielded a positive result. Additional research may be warranted to determine if iciHHV-6 is commonly observed in patients with MIS-C and, if so, whether it may play a part in MIS-C pathogenesis.

Assessing sedation in the pediatric intensive care unit by using BIS and the COMFORT scale.

OBJECTIVE: To evaluate bispectral index technology in critically ill children and compare its performance to standard clinical assessment of sedation level. DESIGN: Prospective convenience sample. SETTING: Multidisciplinary 16-bed pediatric intensive care unit at a large, urban, university-affiliated children's hospital. PATIENTS: Thirty-one pediatric intensive care unit patients requiring mechanical ventilation and sedation. MEASUREMENTS AND MAIN RESULTS: Intubated, sedated, pediatric intensive care unit patients were evaluated for their level of sedation by using bispectral index (BIS) and the COMFORT scale twice daily for up to 5 days. The lowest and highest BIS measurements and their corresponding COMFORT scale measurements were selected from each subject. The mean BIS and COMFORT scale measurements were 62.4 +/- 2.6 and 18 +/- 0.6, respectively; however the individual measurements were only moderately correlated. The BIS values were categorized into very deep (<40), deep (41-60), moderate (61-80), and light (>80) levels of sedation. The corresponding COMFORT scale mean measurements in each category were 15.8 +/- 0.6, 16.2 +/- 0.6, 18.1 +/- 1.3, and 22.3 +/- 1.4 (R(2) =.89). CONCLUSIONS: BIS measurements evaluated in clinically relevant ranges compare favorably with a standard assessment of the level of sedation. However, comparisons of BIS and COMFORT scale measurements at isolated moments during a prolonged pediatric intensive care unit course of sedation were less correlated. BIS may be best used to identify and prevent oversedation of patients in the pediatric intensive care unit.
