Perioperative nutritional support or perioperative fasting? A narrative review
Abstract:
Traditionally, overnight fasting before elective surgery has been Romathe routine in medical practice for risk reduction of pulmonary aspiration of gastric contents. Several original study and international societies recommend a 2h preoperative fast for clear fluids and a 6h fast for solids in most elective patients. We conducted a narrative review of the literature, searching electronic databases (Medline and CINAHL). We used PICO approach. The results of our review suggest that nutrition support in the perioperative period is very important to reduce length of hospital stay and reduced postoperative complication.
