Validity of fasting blood sugar on the day of surgery compared with the preinduction blood glucose level in type II diabetic patients

ABSTRACT

It is necessary that the diabetic patients who are scheduled for elective surgery, be operated as the first cases, but usually it is not possible due to large number of surgeries. The aim of this study was to compare the fasting blood sugar [FBS] on the morning of operation day with pre-operative blood glucose level. Prospective, hospital based study conducted during September 2004-July 2005. Nikookary Hospital, Tabriz Medical Science University, Iran. One hundred patients scheduled for ophthalmic surgery, were enrolled in this study. The levels of fasting and preoperative blood sugar [by lab and glucometery] were measured and compared with the FBS and with each other, as well. There was a significant difference between FBS and pre-operative Blood Sugar glucometery and the laboratory [P< 0.001 and P=0.001, respectively], and also between the mean preoperative BS by the glucometery and the laboratory procedures [P<0.001]. It is not possible to use FBS on the morning of operation day instead of the pre-operative BS level in diabetic patients
