Design of a Clinical Practice Guideline in Nurse-Led Ventilator-Weaning for Nursing Training.

Cardiothoracic intensive care unit (CICU) nurses have shared the role and responsibility for ventilator-weaning to expedite decision-making in patient care. However, the actions taken are based on individual's unstructured training experience as there is no clinical practice guideline (CPG) for nurses in Malaysia. Hence, this study aims to design a CPG for the process of weaning from mechanical ventilation (MV) for a structured nursing training in a CICU at the National Heart Institute (Institut Jantung Negara, IJN) Malaysia. The Fuzzy Delphi Method (FDM) was employed to seek consensus among a panel of 30 experts in cardiac clinical practice on the guidelines. First, five experts were interviewed and their responses were transcribed and analyzed to develop the items for a FDM questionnaire. The questionnaire, comprising of 73 items, was distributed to the panel and their responses were analyzed for consensus on the design of the CPG. The findings suggested that the requirements expected for the nurses include: (a) the ability to interpret arterial blood gases, (b) knowledge and skills on the basics of mechanical ventilation, and (c) having a minimum 1-year working experience in the ICU. On the other hand, the CPG should mainly focus on developing an ability to identify criteria of patient eligible for weaning from MV. The learning content should focus on: (a) developing the understanding and reasoning for weaning and extubating and (b) technique/algorithm for extubating and weaning. Also, the experts agreed that the log book/competency book should be used for evaluation of the program. The CPG for structured nursing training at IJN in the context of the study is important for developing the professionalism of CICU nurses in IJN and could be used for training nurses in other CICUs, so that decision for ventilator-weaning from postcardiac surgery could be expedited.

Compassionate Removal of Heated High-Flow Nasal Cannula for End of Life: Case Series and Protocol Development.

Patients often receive burdensome care at the end of life in the form of interventions that may need to be removed. Heated high-flow oxygen delivered through a nasal cannula (HHFNC) is one such intervention that can be delivered in the hospital yet is rarely available outside of this setting. During the COVID-19 (coronavirus disease 2019) pandemic, health care systems continue to face the possibility of rationing critical life-sustaining equipment that may include HHFNC. We present a clinical protocol designed for weaning HHFNC to allow a natural death and ensuring adequate symptom management throughout the process. This was a retrospective chart review of 8 patients seen by an inpatient palliative care service of an academic tertiary referral hospital who underwent terminal weaning of HHFNC using a structured protocol to manage dyspnea. Eight patients with diverse medical diagnoses, including COVID-19 pneumonia, underwent terminal weaning of HHFNC according to the clinical protocol with 4 down-titrations of approximately 25% for both fraction of inspired oxygen and liter flow with preemptive boluses of opioid and benzodiazepine. Clinical documentation supported good symptom control throughout the weaning process. This case series provides preliminary evidence that the clinical protocol proposed has the ability to ensure comfort through terminal weaning of HHFNC.
