Introduction: All patients posted for surgery are subjected to a series of tests. Recent studies have shown that many of these tests may not be necessary as they do not alter the anaesthetic technique. There are many international guidelines for ordering preoperative investigations. Aim: To determine the proportion of patients who underwent compliant testing and to identify the most common investigations which were not compliant with National Institute for Health and Care Excellence (NICE) guidelines. Materials and Methods: The study was a prospective observational study conducted on all patients undergoing elective surgery at Sri Devaraj Urs Medical College and RL Jalappa hospital, Kolar, Karnataka, India, from May 2022 to July 2022. The grade of surgery and the American Society of Anaesthesiologists (ASA) Physical Status of the patients was noted. The compliance of the tests with NICE guidelines was noted. Results: The preoperative investigations were done in 60 adult patients undergoing elective surgery. Renal function tests were the tests which were the most non compliant (60%) as per NICE guidelines. ECHO, Thyroid function tests and ECG were compliant in 78.3%, 91.7% and 60% of the patients, respectively. Conclusion: The tests which were most non compliant were coagulation profile and renal function tests. Further studies have to be done to check compliance with our Indian guidelines.

BackgroundThis study aimed to compare intraoperative blood sugar level fluctuations between a group of patients receiving Ringer's lactate (RL) fluid as maintenance fluid and another group receiving 0.45% dextrose normal saline with 20 mmol/liter potassium. Materials and methodsThis randomized double-blind study was conducted on 68 nondiabetic patients undergoing elective major surgeries at R. Laxminarayanappa Jalappa Hospital, Sri Devaraj Urs Medical College, Kolar, during the academic year from Jan 2021 to May 2022. Informed consent was obtained from these patients concerning their participation in this study. There were two groups of patients: Ringer lactate (RL) was administered to group A, and 0.45% dextrose normal saline and 20 mmol/L potassium chloride (KCl) were administered to group B. The vitals and blood glucose levels were measured among the patients. A p-value of 0.05 was considered statistically important. ResultsThe mean age of the patients was found to be 43.60 ± 15 years, with comparable age and gender distribution between the groups. On comparison of the mean blood glucose levels immediately after induction was not important between the groups. The mean levels were comparable between the groups (p>0.05). After completion of the surgery, the mean blood glucose level significantly increased in group B patients when compared to those in group A (p<0.05). ConclusionThe study found a substantial increase in intraoperative blood glucose levels among patients receiving 0.45% dextrose normal saline with 20 mmol/liter potassium instead of RL solution as maintenance fluid.
