To explore feasibility and safety of a novel perioperative fasting plan in aged patients who underwent hip fracture surgeries by reducing fasting time both before & after surgeries under the concept of Enhanced Recovery After Surgery (ERAS).

We retrospectively studied all aged (>80y) patients who underwent hip fracture surgeries in our hospital from December 2018 to December 2019 (n=150). All the patients received nutrition risk screening with NRS2002 at admission. Those who may need nutrition supports (NRS2002 ≥3) (n=130) were randomly asigned into control group (n=65) and intervention group (n=65). The control group followed traditional perioperative fasting management while the intervention group followed a novel perioperative fasting plan. Actual perioperative fasting time, perioperative thirst & hunger score, incidences of deliration & PTSD 24hrs post-surgery, incidences of ADRs like aspiration or post-surgery nausea& abdominal distension were compared between the two groups.

There were no significant differences between the two groups in aspiration rates or post-surgery nausea & abdominal distension rates. The intervention group had a significant lower fasting period, perioperative thirst & hunger scores and also lower deliration & PTSD rates 24 h post-surgery. The intervention group had a significant lower hospital stay、accelerated off-bed activities and better degrees of satisfaction.

The novel perioperative fasting plan in aged patients who underwent hip fracture surgeries under the concept of ERAS was proved feasible and safe, which significantly reduced post-surgery ADRs and hospital stay and increased satisfaction degrees.
