Background:
Several studies have investigated the efficacy of enhanced recovery programs in patients undergoing gastrectomy. The role of prehabilitation in these programs has not been evaluated in this subset of patients. This study incorporated incentive spirometry as a type of respiratory prehabilitation in the Enhanced Recovery After Surgery (ERAS) protocol for gastrectomy.
Methods:
In this single-center, prospective, open-labeled randomized controlled trial, 58 patients were randomized into two groups - a conventional perioperative care group and an ERAS group. The patients in the ERAS group received a supervised regimen of preoperative volume-oriented incentive spirometry as respiratory prehabilitation in addition to other ERAS care elements. The length of hospitalization (LOH) was assessed as the primary outcome, while the postoperative peak expiratory flow rate (PEFR) and the incidence of surgical and pulmonary complications were the secondary outcomes.
Results:
The patients in the ERAS group had a shorter median LOH compared to the conventional group (11 days vs 13 days, p = 0.003). The patients in the ERAS group also had smaller fall in postoperative PEFR from baseline, which was significant on the second postoperative day (p = 0.011). None of the patients were found to have anastomotic leaks. The incidence of surgical complications was comparable between the groups (p = 0.137).
Conclusion:
ERAS protocol reduced the duration of hospitalization without increasing the complications compared to conventional perioperative protocol. Respiratory prehabilitation in the form of a supervised schedule of incentive spirometry helped in the preservation of lung functions in the postoperative period.
