Objective  To explore the preventive effect of root cause nursing on acute pressure sore in patients undergoing long time lateral position operation.

  Methods  A total of 310 patients with long-term lateral position operation from September to December 2018 were selected as control group, given routine nursing. A total of 325 patients with long-term lateral position operation from January to April 2019 were selected as observation group, and the root causes of acute pressure sore were analyzed and targeted nursing was adopted. Skin flush, dampness and pressure sore after 24 hours of the operation of two groups were compared. Results There was no significant difference between the two groups in posture position time(P>0.05). At 24 hours after operation, the skin flushing score of the observation group was lower, the temperature at time point of surgery conclusion was higher, and the incidence of intraoperative hypothermia was lower than that of the control group, the differences were statistically significant (P < 0.05). The incidence of operation pressure sore in the observation group was lower than that in the control group, and the area of pressure sore was smaller than that in the control group, the differences were statistically significant (P < 0.05).

  Conclusion  The root cause nursing can prevent the occurrence of acute pressure sore and improve the safety of operation.
