Introducing high-flow nasal cannula oxygen therapy at the intermediate care unit: expanding the range of supportive pulmonary care.

BACKGROUND: Non-invasive respiratory support is a frequent indication for intermediate care unit (IMCU) admission. Extending the possibilities of respiratory support at the IMCU with high-flow nasal cannula oxygen therapy (HFNC) may prevent intensive care unit (ICU) transfer and invasive ventilation. However, the safety and limitations of HFNC administration in the stand-alone IMCU setting are not yet studied. This study therefore aims to investigate to what extent and in which patients HFNC can safely be administered at a stand-alone mixed surgical IMCU. METHODS: A case series, using retrospectively collected data, was performed after the first year of introducing HFNC at a stand-alone IMCU. The following variables were collected: indication to start HFNC, vital parameters and arterial blood gas measurements. Primary outcome was 30-day mortality. Secondary outcome was transfer to the ICU. RESULTS: A total of 96 admissions were included. The indications to start HFNC at the IMCU were predominantly pathologies of pulmonary origin (n=67, 69.8%). Less frequent indications were prolonged support postweaning (n=15), non-pulmonary sepsis (n=7) and post-trauma resuscitation (n=6). The average PaO2/FiO2ratio at start of HFNC was 152 (95% CI 139 to 165). 30-day mortality was 7, of which 5 were admitted with treatment restrictions (no ICU policy) and 2 deaths were unrelated to HFNC. Transfer to the ICU occurred in 18 (18.8%) admissions, of which 12 received invasive mechanical ventilation. Reason for ICU transfer was mainly PaO2/FiO2 ratio<100 under maximum non-invasive treatment (n=12, 66.7%). Application of HFNC at the IMCU prevented 162 days of ICU admission. DISCUSSION: Administration of HFNC at a stand-alone surgical IMCU may be safe as it expands the range of supportive possibilities and thereby reduces the need for ICU admissions. Pulmonary indications to start HFNC increase the risk of ICU transfer and mechanical ventilation. LEVEL OF EVIDENCE: Level VI.

Echocardiography in extracorporeal life support: A key player in procedural guidance, tailoring and monitoring.

Extracorporeal life support (ECLS) is a mainstay of current practice in severe respiratory, circulatory or cardiac failure refractory to conventional management. The inherent complexity of different ECLS modes and their influence on the native pulmonary and cardiovascular system require patient-specific tailoring to optimize outcome. Echocardiography plays a key role throughout the ECLS care, including patient selection, adequate placement of cannulas, monitoring, weaning and follow-up after decannulation. For this purpose, echocardiographers require specific ECLS-related knowledge and skills, which are outlined here.

Outcome in pediatric hydrocephalus: a comparison between previously used outcome measures and the hydrocephalus outcome questionnaire.

OBJECT: The objectives of this study were to assess, in a cohort of children with recently treated hydrocephalus, the correlation between scores on the Hydrocephalus Outcome Questionnaire (HOQ) and the children's type of schooling and motor functioning, and to assess the overall outcome of the children. METHODS: The health status of 142 pediatric patients (85 boys) with previous hydrocephalus, born between 1995 and 1999, was assessed. Outcomes were determined using the HOQ, type of schooling, and motor functioning. Data were obtained from parental interviews and patient medical records. RESULTS. Twelve patients died (8.5%). Responses to the HOQ were obtained from 107 patients (65 boys). The mean age of the patients was 7 years and 9 months +/- 1.42 years (range 6-10 years). The Physical Health score of the HOQ correlated well with the motor functioning score (r = 0.652) as did the Cognitive Health score with the type of schooling (r = 0.672). Fifty-nine percent of the patients were able to attend a school for students with normal intelligence. Disabling motor functioning was found in only 30% of patients. Epilepsy was present in 14%. CONCLUSIONS: The results show a good correlation between the type of schooling and the Cognitive HOQ score and between the Physical HOQ score and the motor functioning score. The HOQ is a simple and very useful measurement for determining outcome in pediatric hydrocephalus.
