Weaning Analgosedation in Patients Requiring Prolonged Mechanical Ventilation. 2022

Although research supports the minimization of sedation in mechanically ventilated patients, many patients with severe acute respiratory distress syndrome (ARDS) receive prolonged opioid and sedative infusions. ICU teams face the challenge of weaning these medications, balancing the risks of sedation with the potential to precipitate withdrawal symptoms. In this article, we use a clinical case to discuss our approach to weaning analgosedation in patients recovering from long-term mechanical ventilation. We believe that a protocolized, multimodal weaning strategy implemented by a multidisciplinary care team is required to reduce potential harm from both under- and over-sedation. At present, there is no strong randomized clinical trial evidence to support a particular weaning strategy in adult ICU patients, but appraisal of the existing literature in adults and children can guide decision-making to enhance the recovery of these patients.

D012121 Respiration, Artificial Any method of artificial breathing that employs mechanical or non-mechanical means to force the air into and out of the lungs. Artificial respiration or ventilation is used in individuals who have stopped breathing or have RESPIRATORY INSUFFICIENCY to increase their intake of oxygen (O2) and excretion of carbon dioxide (CO2).

D015300 Ventilator Weaning Techniques for effecting the transition of the respiratory-failure patient from mechanical ventilation to spontaneous ventilation, while meeting the criteria that tidal volume be above a given threshold (greater than 5 ml/kg), respiratory frequency be below a given count (less than 30 breaths/min), and oxygen partial pressure be above a given threshold (PaO2 greater than 50mm Hg). Weaning studies focus on finding methods to monitor and predict the outcome of mechanical ventilator weaning as well as finding ventilatory support techniques which will facilitate successful weaning. Present methods include intermittent mandatory ventilation, intermittent positive pressure ventilation, and mandatory minute volume ventilation.
