Brief summary

The purpose of this study is to find out if giving a medicine called furosemide, which is a diuretic or water pill, after colon surgery will safely shorten the patient's length of hospital stay.

Detailed description

This study will assess if administration of a loop diuretic, specifically furosemide, to achieve euvolemia can safely reduce length of stay following colorectal surgery.

Interventions

DRUGFurosemide
DRUGCelecoxib

Celecoxib is a nonsteroidal anti-inflammatory drug (NSAID) used to treat pain or inflammation.

DRUGGabapentin

Gabapentin is a oral drug used to treat seizures, postherpetic neuralgia, and restless legs syndrome.

MeasureTime frameDescription
Length of Hospital StayUp to 7 daysParticipants will be followed for the duration of hospital stay, an expected average of 2-7 days.

Secondary

MeasureTime frameDescription
Number of Participants Readmitted to Mayo Clinic Within 30-daysWithin 30 days of release from hospital
Number of Participants Requiring Nasogastric Tube PlacementUp to 7 days
Time to Stool OutputUp to 4 days
Number of Participants With Acute Kidney InjuryUp to 7 daysAcute kidney injury (AKI) refers to an abrupt decrease in kidney function, resulting in the retention of urea and other nitrogenous waste products and in the dysregulation of extracellular volume and electrolytes. The term AKI has largely replaced acute renal failure (ARF), reflecting the recognition that smaller decrements in kidney function that do not result in overt organ failure are of substantial clinical relevance and are associated with increased morbidity and mortality. The AKI experienced by these patients was not considered an adverse event.
Number of Participants With HypokalemiaUp to 7 daysHypokalemia is generally defined as a serum potassium level of less than 3.5 mmol/L.

Recruitment details

Subjects were enrolled at Mayo Clinic in Rochester, Minnesota between February 2015 and April 2016.

Participants by arm

ArmCount
Furosemide + Enhanced Recovery After Surgery (ERAS)
Furosemide 10 mg IV on post-operative day #1 and/or 2, plus ERAS, as described in other arm.
62
Enhanced Recovery After Surgery (ERAS)
ERAS included administration of celecoxib and gabapentin in the pre-operative setting, single-injection intrathecal analgesic administration immediately prior to induction of general anesthesia, post-operative administration of scheduled acetaminophen and nonsteroidal anti-inflammatory drug (NSAID) or tramadol, and discontinuation of IV fluids by 0800 on postoperative day (POD) 1. Intraoperative fluid administration was dependent on the individual anesthesia provider with no unified commitment to either zero balance or goal-directed fluid therapy. Fluid status was determined based on patient weight. Patients were weighed preoperatively and daily post-operatively using either a bed scale or a unit-based scale.
