The aim of our study was to compare intracuff 2% alkalinized lignocaine with 1% alkalinized lignocaine and saline in reducing endotracheal tube induced emergence phenomena and haemodynamic changes at extubation in neurosurgical patients. <b>Materials and Methods</b>  In this randomized controlled study, 90 adult patients of either sex, scheduled to undergo neurosurgical procedures were randomly divided into three groups of 30 each to receive either 1% alkalinized lignocaine (AL1), 2% alkalinized lignocaine (AL2), or saline as cuff inflation media. Intracuff pressures and haemodynamic variables were noted intraoperatively and during emergence. The presence of postextubation cough, sore throat, dysphonia, and dysphagia were monitored until 24 hours postoperatively. Data were analyzed using Chi-square test and ANOVA. A <i>p</i> -value of less than 0.05 was considered significant. <b>Results</b>  The intracuff pressures were significantly less with alkalinized lignocaine as compared to saline, after 3 hours of induction. Post extubation, hemodynamic parameters and incidence of coughing and bucking at extubation were significantly less in Groups AL1 ( <i>p</i>  = 0.024) and AL2 ( <i>p</i>  = 0.02) as compared to saline. On assessment of laryngotracheal morbidity, the incidence of coughing was found to be significantly less with 2% alkalinized lignocaine as compared to saline ( <i>p</i>  = 0.021) at 1 hour after extubation. Sore throat was significantly less in Groups AL1 and AL2 as compared with saline at 1 hour ( <i>p</i>  = 0.008, 0.002 respectively) and 8 hours ( <i>p</i>  = 0.01 in both groups), and in Group AL2 versus saline at 24 hours ( <i>p</i>  = 0.044) after extubation. The incidence of dysphonia was significantly less in Groups AL1 and AL2 as compared with saline at 1 hour ( <i>p</i>  = 0.016, <i>p</i>  = 0.002) and 24 hours ( <i>p</i>  = 0.012 in both groups) and in Group AL2 versus saline at 8 hours <i>(p</i>  = 0.03) postoperatively.

We evaluate the efficacy and safety of this technique for the distal transsylvian approach.

Acetazolamide reduces CSF production by 48%. The actual role of acetazolamide in the amelioration of traumatic CSF rhinorrhea and otorrhea is not clear as, till date, very few formal studies have been conducted. Aim of the study was to determine the role of acetazolamide in traumatic cerebrospinal fluid rhinorrhea and otorrhea. <b>Materials and Methods</b>  A randomized controlled trial was conducted among 134 patients with head injuries presenting to the neurosurgery department of a tertiary care center in North India, with complaints of CSF rhinorrhea and otorrhea within 72 hours of traumatic injury. One-hundred thirty-four patients were randomized into intervention and control group. Comparative analysis was not possible in 58 patients as in due course they were either operated for head injury or lumbar drain was put due to excessive CSF leak; hence, forth comparative analysis was done in 76 patients. Out of these 76 patients, 44 patients belonged to the intervention group (Acetazolamide given) and 32 belong to the control group (Acetazolamide not given).

The complication associated with CSF leak was meningitis.

The nomenclature has also advocated the routine use of immunohistochemistry in describing the pituitary transcription factors that plays a fundamental role in distinguishing the cell lineage of these tumors.
