Method: In this study 20 patients undergoing maxillofacial surgery were randomized into four groups i.e. e group I patients with standard 08 h fasting before anesthesia, group-II patients were given 400 ml and 200 ml of water 08 h and 2 h respectively before anesthesia, group III patients were given 400 ml water with 50 gms of glucose and 40 gm of glutamine 08 h before anesthesia and 200 ml water with 25 gms of glucose and 10 gm of glutamine 2 h before anesthesia, group IV patients were given 400 ml water with 50 gms of glucose 08 h before anesthesia and 200 ml water with 25 gms of glucose 2 h before anesthesia. Blood samples were collected pre-operatively and post-operatively. Discussion: This study shows that shortening of pre-operative fasting time for clear fluids until 2-h prior to anesthesia may induce a favorable environment for the post-operative course. In conclusion, Glutamine with carbohydrate drink can be used safely in surgical patients.

Aim of the Study The present study evaluated the cardiovascular changes related to anxiety of the patient undergoing local anesthesia injection for extraction in Indian population. Methodology In total, 100 Indian male patients were enrolled in the prospective study. Anxiety was measured at 15 min before local anesthetic delivery using Corah's Dental Anxiety Scale (DAS). Cardiovascular response data including blood pressure, heart rate, oxygen saturation and electrocardiographic changes were measured at five time points from 5 min before to 15 min after the administration of anesthetic. Results The mean anxiety scale score before administration of anesthetic was 8.24 (± 3.55) with a range from 4 to 20. Younger age was associated with a higher anxiety scale score. Severe preoperative anxiety (DAS [ 12) was associated with significantly increased heart rate and blood pressure during administration of anesthetic. Significant ECG change was present at the time and 5 min after local anesthesia administration. Pain on injection was also associated with increased heart rate and blood pressure during anesthetic administration. Conclusion The present study shows that significant cardiovascular changes do occur due to dental anxiety at the time of local anesthesia administration for tooth extraction in Indian population.

Khoshnevisan et al. (2007) proposed a general family of estimators for population mean using known value of some population parameters in simple random sampling. The objective of this paper is to propose a family of combined-type estimators in stratified random sampling adapting the family of estimators proposed by Khoshnevisan et al. (2007) under non-response. The properties of proposed family have been discussed. We have also obtained the expressions for optimum sample sizes of the strata in respect to cost of the survey. Results are also supported by numerical analysis.
