Effects of Single Dose of Dexamethasone on Perioperative Blood Glucose Levels in Patients Undergoing Surgery for Supratentorial Tumors - An Observational Study.

Introduction: Dexamethasone is commonly administered in intracranial tumors to reduce the cerebral edema. Its administration may be associated with hyperglycemia. The primary objective of this study was to study the magnitude of rise in blood sugar levels following the administration of a single 10 mg dose of dexamethasone.

A Randomized Study Comparing the Sniffing Position with Simple Head Extension for Glottis Visualization and Difficulty in Intubation during Direct Laryngoscopy.

Background: Proper positioning of the head and neck is important for an optimal laryngeal visualization. Traditionally, sniffing position (SP) is recommended to provide a superior glottic visualization, during direct laryngoscopy, enhancing the ease of intubation. Various studies in the last decade of this belief have challenged the need for sniffing position during intubation.

Blood transfusion practices in neuroanaesthesia.

Neuroanaesthesia practice is associated with risk of significant blood loss resulting in anaemia in the intraoperative and postoperative period. The transfusion triggers in a neurologically injured brain are not clearly defined. Both a low haematocrit and a high haematocrit have not shown any improvement in the outcome.
