Abstract:
Objective To evaluate the effects of different bedside elevation angles on ventilator-associated pneumonia and pressure sores in critically ill patients with mechanical ventilation.Methods The randomized controlled trials of raising the angle of the bed at the Cochrane Library,JBI,PubMed,Embase, Ovid,CMB,VIP,CNKI and Wanfang database on ventilator-associated pneumonia and pressure sores in critically ill patients with mechanical ventilation were retrieved. Meta-analysis was performed on the included literatures after including literature review,evaluation and extraction by 3 researchers.Results A total of 6 literatures were included involving 518 patients. The overall quality of the included literature was medium The results of meta-analysis showed that the incidence rate of VAP in patients with bedside elevation angles >30° was significantly lower than that in patients with bedside elevation angles ≤30° (OR=0.42,P=0.02). There was no significant difference in the risk of pressure sore (OR=0.85,P=0.55). There was no significant difference in the increase of death outcome (OR=0.86,P=0.52).Conclusions In the clinic,it is appropriate to raise the head of a bed more than 30°without any contraindication,but further attention should be paid to the durability of raising the head of a bed more than 30°and the medical staffs' compliance.
