The glucocorticoid dexamethasone in a bolus dose of 8-10 mg followed by quarterly dose of 4 mg is commonly used during intracranial surgery so as to reduce oedema and vascular permeability. However, the detrimental hyperglycaemic effects of dexamethasone may override its potentially beneficial effects. The present prospective, randomised study aimed at comparing the degree and magnitude of hyperglycaemia induced by prophylactic administration of dexamethasone in patients undergoing elective craniotomy. ⋯ Peri-operative administration of dexamethasone during neurosurgical procedures can cause significant increase in BG concentration especially in patients who receive dexamethasone intra-operatively only.

External ventricular drains (EVD) are commonly utilized for temporary diversion of cerebrospinal fluid (CSF). Many neurosurgeons prefer long-tunneled EVDs in their routine practice. However, it is still unclear whether this extended tunneling helps in reducing CSF infection. Keeping this in mind, we decided to compare infection rates in long-tunneled versus short-tunneled EVDs in the setting of a developing country. ⋯ Long-tunneled EVDs appear to only delay potential infections without having any effect on the actual risk of infection. Long-tunneled EVD in a resource-limited setting is technically challenging and may not yield additional benefits to the patient. However, larger and prospective studies are needed to establish the rate of infections and other complications.
