Objective To explore the practicability and clinical significance of gastric tube insertion by left recumbent position for patients with exanimation. Methods We divided 100 patients with exanimation who needed gastric tube insertion into the routien group and the left-recumbent-position group with 50 cases in each group randomly and adopted routine insertion method and insertion by left recumbent position.The success rate of tube insertion and incidence of complications were observed in the two groups.Results The one-time success rate of insertion was higher while the incidence of complication was lower in the left-recumbent-position group compared with the control group (P<0.05). Conclusion Gastric tube insertion by left recumbent position proved to be a desirable method in that it could increase the onetime success rate of insertion and decrease the complications.So it worth widely applying.

Objective To investigate the effect of intensive control of residual amount in stomach on prevention of ventilator associated pneumonia(VAP)during the process of enteral nutrition. Methods 96 patients with mechanical ventilation(MV) more than 48 hours were randomly divided into the case group and the control group, they were treated with intensive control and common control of residual amount in stomach respectively. The incidence rate of VAP, mortality rate, time of ventilation and hospitalization time were compared between the two groups. Results The incidence rate of VAP was 20.83% in the case group and mortality rate was 18.75%,the time of MV was(15.21±2.36)days, the hospitalization time was(22.38±12.34)days. The incidence rate of VAP wag 39.58%.mortality rate was 39.58%,the time of MV wag(19.85±4.58)days, the hospitalization time was(29.46±15.24)days in the control group. Conclusions Intensive control of residual amount in stomach could be helpful to decrease the incidence of VAP and mortality rate of patients with mechanical ventilation using nasal feeding, also shorten the time of MV and the hospitalization time.
