This study was a retrospective database review of 2447 non-diabetic postoperative colorectal surgical patients in which 16,407 glucose measurements were obtained over a 2 year period. Nondiabetic patients were identified as those without a preoperative diagnosis of diabetes and/or based on HbA1C levels. The association between any elevated postoperative random glucose value (hyperglycemia: >125 mg/dL) and level of elevation (>125 mg/dL or >200 mg/dL) within 72 hours of surgery and 30-day mortality and infectious and noninfectious complications was assessed. Significant associations were found between postoperative hyperglycemia
and the length of operation, extent of blood loss, and transfusion requirements. Hyperglycemia (mild or severe) was associated with increased rates of infectious complications (superficial
and deep SSI, urinary tract infections), sepsis, acute renal failure, reintubation and a greater LOS. The risk for complications increased with an increasing level of postoperative glycemia. Reoperations were twice as frequent for patients with severe hyperglycemia
when compared with those with normoglycemia (7.3% vs 3.1%, P = 0.006). Although rare, postoperative mortality was significantly associated with postoperative glycemia, with only 1 (0.12%) patient with normoglycemia having died during the first 30 postoperative days as
compared with 4 (1.2%) of the patients who had 1 or more values of severe postoperative hyperglycemia.
1. Hyperglycemia in this article was defined as a glucose level greater than 125 mg/dl
a. During the entire postoperative stay
b. Within 24 hours of surgery
c. Within the first 48 hours post surgery
d. Level obtained prior to infection.
2. True OR False
Steroid use was associated with a greater risk of reoperation and length of stay in these non-diabetic colorectal surgical patients.
3. True or False
A single postoperative episode of elevated glucose in this study was associated with a greater risk of morbidity and mortality.
4. Tight glycemic control
a. Was associated with a decrease in surgical site infections
b. Decreased mortality
c. a & b
d. None of the above
