Transition of prolonged mechanical ventilation in children from PICU to family and humanistic care / 中国小儿急救医学

With the improvement of pediatric treatment level, the number of children with prolonged mechanical ventilation has increased rapidly.The transition of children from PICU to home mechanical ventilation is a very complex and arduous process that requires multi-faceted support and management.Long-term mechanically ventilated children and their families bear a huge social and psychological burden, and they need psychological support and humanistic care from the society.

The concept and research progress of long-term mechanical ventilation in children / 中国小儿急救医学

In recent years, the number of children with prolonged mechanical ventilation has increased rapidly, and they have been in intensive care units for a long time, resulting in a heavy disease burden and high mortality.Families and society are also paying more and more attention to this special group.The United States and Canada have issued a management consensus on mechanical ventilation for children at home, but the allocation of medical resources in China and other countries is very different, and the domestic family-centered management plan is still difficult at this stage.This review summarized the current status of long-term mechanical ventilation in children in China and other countries, and hoped to learn from foreign experience to help domestic children with long-term mechanical ventilation better.

Pediatric Home Mechanical Ventilation in Korea: the Present Situation and Future Strategy

BACKGROUND: The number of children using home mechanical ventilation (HMV) has increased markedly in Europe and North America, but little is known about the situation in Korea. We described the clinical characteristics of children using HMV and investigated the current situation of HMV utilization in children. METHODS: Data on HMV prescriptions in year 2016 for children under the age of 19 was retrieved from the National Health Insurance Service for nationwide information. For more detailed information, data from year 2016 to 2018 was also retrieved from a tertiary center, Severance Children's Hospital. RESULTS: Nationwide, 416 children were prescribed with HMV in 2016, with an estimated prevalence of 4.4 per 100,000 children, of which 64.2% were male and mean age was 6-year-old. The estimated number of patients using invasive ventilators via tracheostomy was 202 (49%). Neuromuscular diseases were the most frequent cause (217; 52%), followed by central nervous system diseases (142; 34%), and cardiopulmonary diseases (57; 14%). In the tertiary center, a total of 62 children were prescribed with HMV (19 [31%] with non-invasive ventilation; 43 [69%] with invasive ventilation]. The number of children with HMV increased from 11 in 2016 to 29 in 2018. The mean age for initiation of HMV was 3.1 years and male patients comprised 65%. The most frequent diagnostic reason for HMV was central nervous system diseases (68%), followed by cardiopulmonary diseases (19%) and neuromuscular diseases (13%). Five patients died during the study period and five patients weaned from HMV. CONCLUSION: This study provides insights on the present situation of HMV utilization in Korean children.

El modelo de atención podría ser determinante de deficiencias en el control de calidad de este tratamiento. Material y métodos: Con la finalidad de monitorear el cumplimiento de la ventilación mecánica domiciliaria y optimizar su eficacia, propusimos un programa mediante hospital de día conducido por médicos neumonólogos y kinesiólogos respiratorios. Se diseñó un estudio descriptivo sobre una base de datos de recolección sistemática. Participaron pacientes consecutivos con ventilación no invasiva o asistencia respiratoria mecánica invasiva asistidos en el Servicio de Neumonología entre julio de 2014 y diciembre de 2016. Resultados: Participaron 94 pacientes; 52 hombres (55%), edad 64.4 ± 15.9 años; el 50% presentaban obesidad o sobrepeso (índice de masa corporal 28.6 ± 8.46 kg/m²). Recibían ventilación mecánica domiciliaria 80 pacientes (84%); no invasiva en 77 casos e invasiva en tres (4%). Se admitieron para evaluar la indicación de ventilación mecánica domiciliaria 14 pacientes (14.8%). Los modos de ventilación no invasiva utilizados fueron; bilevel S/T: 59 (62.7%), presión de soporte con volumen promedio asegurado (AVAPS average volume-assured pressure support ventilation); 4 (4.2%), presión positiva continua en la vía aérea (CPAP (continuous positive airway pressure): 6 (6.4%), servo-ventilación: 1 (1%). Tres pacientes recibían ventilación volumétrica. La media de cumplimiento fue de 8.1 horas. Cuatro pacientes no utilizaban el dispositivo. Permanecieron hipercápnicos el 42.5%. Se cambió la programación en 37 pacientes (46.2%), modo ventilatorio en 2 (2.5%) y se suspendió la ventilación en dos (2.5%). En pacientes individuales los ajustes fueron clínicamente significativos. Conclusión: El programa permitió mejorar el entrenamiento e identificar un alto porcentaje de ventilación mecánica domiciliaria ineficaz, permitiendo ajustes en la modalidad de tratamiento.

Introduction: Home mechanical ventilation (HMV) represents a standard of care for chronic ventilatory pump failure. The care model could be determinant in deficiencies in the control of quality of HMV. Material and methods: In order to monitoring compliance during home mechanical ventilation and optimize its effectiveness, we proposed a program through a day hospital conducted by pulmonology doctors and respiratory physiotherapist. A descriptive study was designed on a systematic collection database. Participants were consecutive patients with NIV or mechanical invasive ventilation (MIV) assisted in the Pulmonology Service between July 2014 and December 2016. Results: During 30 months we included 94 patients; 52 men (55%), age 64.4 ± 15.9 years and BMI of 28.6 ± 8.46 kg / m². Fifty percent were obese or overweight. 80 were found with HMV (84%) noninvasive (NIV) in 77 cases and invasive in three (4%). 15 patients (16%) were admitted to evaluate indication of VMD. The NIV modes used were; Bilevel S / T: 59 (62.7%), AVAPS; 4 (4.2%), CPAP: 6 (6.4%), servo-ventilation: 1 (1%). Three patients received volumetric ventilation. The mean compliance objectively measured was 8.1 hours. Four patients did not use the device. Remained with hypercapnia 42.5%. The setting was changed in 37 patients (46.2%), ventilatory mode in 2 (2.5%) and HMV was suspended in two (2.5%). In individual patients adjustments were clinically significant. Conclusion: This program allowed to improve the training and to identify a high percentage of patients with ineffective HMV, allowing adjustments in the modality of treatment.

Ventilação mecânica domiciliar: uma realidade cada vez mais frequente / Mechanical ventilation home: an increasingly frequent reality

Desde que a ventilação mecânica foi difundida após a epidemia de poliomielite até os dias atuais com o avanço das estratégias diagnósticas e terapêuticas, houve significativo aumento na sobrevida dos pacientes criticamente enfermos. Este subgrupo de sobreviventes encontra-se em um estado cronicamente crítico e dentre outras disfunções e terapias de suporte, caracteriza-se pela necessidade de ventilação mecânica prolongada. Paralelo a este fato, o envelhecimento populacional eleva a chance de internações hospitalares com necessidade de assistência ventilatória invasiva. Nos dias de hoje, a ventilação mecânica domiciliar é uma realidade e tornou-se uma opção viável para pacientes com insuficiência respiratória crônica, também estimulada pelo crescimento da utilização de ventilação não invasiva com pressão positiva, o reconhecimento de diferentes tipos de pacientes que podem se beneficiar desta técnica e redução dos custos hospitalares através da desospitalização.Atualmente possuímos diversos tipos e modelos de ventiladores exclusivos para ventilação mecânica domiciliar, assim como interfaces e a escolha do dispositivo ideal para cada paciente pode ser uma tarefa árdua. Porém não pode ser esquecido que o objetivo principal da utilização da ventilação domiciliar deve ser o controle dos sintomas decorrentes da doença do paciente e consequente melhora da qualidade de vida...

Since mechanical ventilation was widespread after the polio epidemic to the present day with the advancement of diagnostic and therapeutic strategies, a significant increase in survival of critically ill patients. This subgroup of survivors is in a critical state and chronically various etiologies and therapies support, characterized by the need for prolonged mechanical ventilation. Parallel to this fact, population aging increases the chance of hospitalizations requiring invasive mechanical ventilation. Today, home mechanical ventilation is a reality and has become a viable option for patients with chronic respiratory insufficiency, also encouraged by the increasing use of noninvasive positive pressure ventilation, recognition of different types of patients who may benefit from this technique and reduced hospital costs through deinstitutionalization.We currently have various types and models of home mechanical ventilatiors, as well as interfaces and choosing the right device for each patient can be a chore. But it can not be forgotten that the main purpose of using home ventilation is to control the symptoms of the patient’s illness and consequent improvement in quality of life...

Home Mechanical Ventilation in South Korea

PURPOSE: To survey the use of invasive and noninvasive home mechanical ventilation (HMV) methods in South Korea from the perspective of physical medicine and rehabilitation (PM&R). MATERIALS AND METHODS: For 413 users of HMV, retrospective reviews of PM&R interventions and survey of HMV methods employed from Mar 2000 to Dec 2009. RESULTS: Of the 413 users, the majority of whom with progressive neuromuscular disorders (NMDs) (n=358), 284 patients initially used noninvasive mechanical ventilation (NIV), while 63 others who were using tracheostomy mechanical ventilation switched to NIV as part of their rehabilitation. The NMD patients began HMV at an earlier age (34.9+/-20.3 yrs), and used for longer (14.7+/-7.5) hours than patients with non-neuromuscular causes of respiratory impairment. CONCLUSION: Noninvasive management was preferred over invasive ones, and transition to the former was a result of PM&R interventions.

Recommendations for hygiene of masks and circuits in mechanically home ventilated patients

Home mechanical ventilation requires equipment, consisting of a generator of pressure, a tubing and an interface to deliver air to the patient. Instructions for equipment maintenance are generally not based on scientific evidence. Studies however have reported that tubing and masks used at home are the most commonly found as very dirty and contaminated. Dirtiness and contamination of equipment potentially expose patients to a higher risk of airway colonization, which, in turn, should cause respiratory infections. For this reason, published hygiene instructions include the use of disinfectant solution. Nevertheless, they generally fail to explain how basic maintenance may be achieved by simple cleaning with soap and water. The instructions for post-cleaning disinfection will depend upon the relative sensitivity of patients to respiratory tract infections and the related risks for bacterial colonization of the airways. Restrictive and obstructive disease patients are not equally sensitive to infections and, as a consequence, should not require similarly elaborate disinfection level. According with the restrictive or obstructive origin of respiratory insufficiency, the current educational review suggests simple and adequate rules for hygiene of tubing and masks in the home setting. Written instructions on how to clean the equipment for home ventilation are useful and sufficient in restrictive patients. In obstructive patients, cleaning always precedes disinfection. After cleaning, rinsing and drying are important. An effective weekly 20-minute disinfection may be achieved by using an hypochlorite solution of soaking in a concentration of 0.5 percent.

Clinical Study of Children Using Home Mechanical Ventilation / 소아과

PURPOSE: The use of mechanically-assisted ventilators at home reduces morbidity and improves the quality of life in children with chronic respiratory failure. But in Korea there is no clinical data of children with home mechanical ventilation. We investigated ventilator types, duration, the causes of failure or death, and the cost needed for care. METHODS: We retrospectively analyzed the medical records of 21 children who were admitted and who applied for home mechanical ventilation at the Pediatric Intensive Care Unit in Asan Medical Center. Phone interviews took place after discharge. and interviewed by phone after discharge. RESULTS: The median age was 31 months; the median duration with ventilator was 25 months. Underlying diseases were 16 neuromuscular diseases, one metabolic disease and four chronic respiratory diseases. The types of ventilator were pressure and volume type(16 and five patients, respectively). The frequency of ventilation failure was once per 19 months. Weaning could be performed in three cases. Frequencies of admission after receiving ventilators were 1.7 times per year; the most common cause was pneumonia. Nine patients(43%) died; four of them died because of endotracheal tube obstruction. The costs for medical care were about 1,110,000 won per month. CONCLUSION: There is an increment in the numbers of individuals who need mechanical ventilation support. The most common cause of death was endotracheal tube obstruction. The most important problem for the patients was medical cost. There needs to be more interest in patients with ventilator and social welfare systems to support their families need to be prepared.
