Through evolving research, recent years have witnessed remarkable achievements in neuromonitoring and neuroanesthetic techniques, with a huge body of literature consisting of excellent studies in neuroanaesthesiology. However, little of this work appears to be directly important to clinical practice. Many controversies still exist in care of patients with neurologic injury. ⋯ Till date, nimodipine is the only drug with proven efficacy in preventing cerebral vasospasm. In neurocritically ill patients, intensive insulin therapy results in substantial increase in hypoglycemic episodes and mortality rate, with current emphasis on minimizing glucose variability. Results of ongoing multicentric trials are likely to further improvise our practice.

Ineffective face mask seal is the most common cause for suboptimal pre-oxygenation. Room air entrainment can be more with vital capacity (VC) breaths when the mask is not a tight fit. ⋯ TV breathing for 5 min provides better pre-oxygenation in patients with ineffective mask seal with fresh gas flow of 10 L/min delivered through a circle system.

Different additives have been used to prolong brachial plexus block. We performed a prospective, randomised, double-blind study to evaluate the effect of dexamethasone added to lidocaine on the onset and duration of supraclavicular brachial plexus block as this is the most common type of brachial block performed in our institute. ⋯ Addition of dexamethasone to 1.5% lidocaine with adrenaline in supraclavicular brachial plexus block speeds the onset and prolongs the duration of sensory and motor blockade.

Literature suggests glottic view is better with straight blades while tracheal intubation is easier with curved blades. ⋯ We found that in patients with normal airway glottis was best visualised with Miller blade and Trueview(®) laryngoscope however, the trachea was more easily intubated with McCoy and Macintosh blades and Trueview(®) laryngoscope.
