Meta AnalysisKetamine sedation in mechanically ventilated patients: A systematic review and meta-analysis.
Ketamine use as a sedative agent in mechanically ventilated patients is increasing. This systematic review and meta-analysis collates existing literature and quantifies the impact of ketamine in mechanically ventilated patients. ⋯ The data regarding ketamine use in mechanically ventilated patients is limited in terms of quantity, methodological quality, and demonstrated clinical benefit. Ketamine may play a role as a sedative-sparing agent, but may be associated with harm. High-quality studies are needed before widespread adoption of ketamine earlier in the sedation pathway.

Multicenter Study Clinical Trial Observational Study
Predictors of Extubation Failure Related to Aspiration and/or Excessive Upper Airway Secretions.
Extubation failure may have several causes, including swallowing dysfunction, aspiration, and excessive upper airway secretions. We hypothesized that a bedside global swallowing pattern assessment including 9 criteria (volume of pharyngeal secretions, 5 swallowing motor items, swallowing reflex, and 2 gag reflexes) performed prior to extubation could identify patients at risk of extubation failure. ⋯ In subjects with prolonged ventilation, the presence of one or both gag reflexes could predict a reduction in extubation failure related to aspiration or excessive upper airway secretions. (Clinical trials.gov registration NCT00780078.).

Observational StudyEffects of intraoperative tidal volume on incidence of acute kidney injury after cardiovascular surgery: A retrospective cohort study.
We performed a retrospective cohort study to evaluate whether intraoperative low tidal volume ventilation reduces the incidence of acute kidney injury (AKI) after cardiovascular surgery. ⋯ This study suggests that intraoperative low tidal volume ventilation during cardiovascular surgery is associated with a decreased incidence of postoperative AKI. Lowering tidal volume might be a simple strategy for reducing AKI incidence after cardiovascular surgery.

Arterial oxygen tensions in mechanically ventilated ICU patients and mortality: a retrospective, multicentre, observational cohort study.
Supplemental oxygen therapy is commonly required for respiratory failure requiring mechanical ventilation in the ICU. However, hyperoxaemia may be injurious and may increase mortality. We evaluated the relationship amongst the degree of hyperoxaemia and changes in fraction of inspired oxygen (Fio2) in response to hyperoxaemia, as well as associations with mortality in mechanically ventilated ICU patients. ⋯ In mechanically ventilated ICU patients, hyperoxaemia was common. Although oxygen supplementation was often reduced when hyperoxaemia was observed, several patients remained hyperoxaemic. Hyperoxaemia was associated with increased ICU mortality in these patients.

Multicenter Study
Critical care nurses' perception of care coordination competency for management of mechanically ventilated patients.
To evaluate nurses' care coordination competency for mechanically ventilated patients in intensive care units (ICUs) of Saudi Arabia (SA). ⋯ The results provide information on the status and gaps in ICU nurses' care coordination competencies to address the needs of mechanically ventilated critically ill patients. The NCCCS can be utilised as an educational tool for nurses who are new to the ICU work environment.
