Abstract:

Objective To evaluate the relevant evidence of bedside sitting in ICU awake patients with mechanical ventilation，so as to provide a reference for clinical medical staff to implement their practice of bedside sitting. Methods Based on PIPOST，evidence-based questions were identified，search strategies were developed，and all guidelines，evidence summaries，best practice information books，recommended practices，systematic reviews and original studies on bedside sitting of mechanically ventilated awake patients in ICU were searched by computer in professional guide networks，association networks and databases at home and abroad. The quality evaluation，evidence extraction and evidence summary of the included literatures were carried out by the evidence-based team. Results 14 literatures were included，including three guidelines，a systematic review，an evidence summary and nine original studies. 25 pieces of evidence were summarized into 11 dimensions，including the establishment of multidisciplinary team，bedside sitting education，bedside sitting assessment，bedside sitting start time，bedside sitting preparation，bedside sitting mode，bedside sitting frequency，ventilator mode selection，patient placement，bedside sitting monitoring management，and termination standards. Conclusion Bedside sitting in awake patients with mechanical ventilation in ICU has important practical significance. Medical staff should scientifically manage bedside sitting according to the heterogeneity of bedside sitting，strengthen the quality control of bedside sitting，and ensure the safety of patients.
