Weaning A Critical Element - 1791 Words

Weaning Weaning is a critical element in the care of intubated patients that deals with the entire technique of liberating the patient from mechanical ventilatory support as well as from the endotracheal tube. It is the transition of ventilatory support to spontaneous breathing (30). Although it can be achieved easily in many patients, it may prove to be difficult in up to 25% of critically ill patients who have been on ventilation for a prolonged period of time (31–33). Shorter the time in MV, lesser would be the complications associated with it by as much as 50%, with decrease in number of re-intubation as well (34). Study by Esteban et al. suggested that mortality rate is related to increased duration of mechanical ventilation wherein weaning period accounted for 40% of the ventilatory time (2). Similarly study by Coplin further shows the relevance of timely extubation by relating the delayed extubation with increased mortality rate of 27% against the rate of 12% in timely ex tubated patients (3). Although some researchers assessed that around 80% of intubated patients could discontinue ventilatory support in a matter of hours (2,9,35), weaning could be complicated by abnormal lung function or the presence of underlying disease (35). Other issues such as critical illness, neuromyopathy, prolonged use of sedatives, overloading or underloading of respiratory muscles and physician’s hesitancy to identify weaning and extubation readiness may also delay the weaningShow MoreRelatedThe Role Of Uk Weaning Guidelines And The Sources Of Weaning Advice Used By Uk First Time Mothers1637 Words   |  7 PagesIn another mixed method study to explore the knowledge of the UK weaning guidelines and the sources of weaning advice used by UK first-time mothers (Moore et al, 2012), findings were quite similar to the first study.

The choice of Analgesia and Sedation can be assessed properly using the Richmond Agitation-Sedation Scale (RASS) and can decrease the chances of a patient becoming over sedated. Choosing between analgesia and sedation can affect the weaning process, length a patient is ventilated, and how long a patient is in the ICU and potentially developing deliriumRead MoreThe Analysis : Lactation And Breastfeeding1343 Words   |  6 Pagesincreasing numbers of women working outside the home.
