Enrollment: 121 participants; Allocation: RANDOMIZED; Intervention model: PARALLEL

Brief summary:
The purpose of this study is to evaluate the effect of low dose versus high dose steroids vital signs of patients currently on steroids or recently treated with steroids undergoing major colorectal surgery. The investigators hypothesize that there will be no statistically significant difference in orthostatic hypotension (blood pressure measured on lying, sitting, and standing), blood pressure, temperature or heart rate in the standard and low dose groups.

Detailed description:
Our primary aim is to study the perioperative hemodynamic profile of patients on chronic steroids undergoing colon and rectal surgery. We will do this by measuring heart rate, temperature and blood pressure in the operating room and during their postoperative hospitalization. Patients will be identified in their preoperative visit. They will be randomized to high dose and low dose steroid study groups. The standard dose steroid patients will receive hydrocortisone 100 mg IV preoperatively and 100 mg IV every 8 hrs with standard taper. The low dose steroid study group will receive the IV equivalent of their preoperative steroid dose in the postoperative period. The patients blood pressure, temperature and heart rate will be monitored in the operating room and the ward postoperatively. Outcomes will be compared between the two groups. We hypothesize that there will be no statistically significant difference in blood pressure, temperature or heart rate in the high dose and low dose groups.

The secondary aim of this study will be monitoring of any differences in surgical outcomes, including postoperative length of stay, between the two patient groups.

Arms: arm 1: Intervention: Patients receive Hydrocortisone 100 mg at surgical incision followed by 100mg IV every 8 hours for the first 24 hours, followed by 75 mg IV every 8 hours for 24 hours, followed by 50 mg IV every 8 hours for 24 hours, followed by 50 mg IV every 12 hours, followed by Prednisone 20 mg orally when oral diet is resumed arm 2: Intervention: 1/3 Intravenous equivalent dose (IVED) at surgical incision, followed by 1/3 IVED for 24 hours, Patients subsequently treated with 1/4 IVED every 8 hours starting Postoperative day (POD) 1, followed by 1/6 IVED every 8 hours on POD 2 and every 12 hours starting POD 3. On POD 4 or when the patient was tolerating a regular diet, oral prednisone equal to the most recent IV hydrocortisone dose resumed
