Randomized Controlled Trial Comparative StudyA comparative study between the effects of 4% endotracheal tube cuff lignocaine and 1.5 mg/kg intravenous lignocaine on coughing and hemodynamics during extubation in neurosurgical patients: a randomized controlled double-blind trial.
A prospective, randomized double-blind trial was performed to compare the effects of 4% endotracheal tube cuff lignocaine and 1.5 mg/kg intravenous (IV) lignocaine on coughing and hemodynamics during extubation in patients undergoing elective craniotomies in supine position. Forty-one patients received 4% lignocaine into the endotracheal tube cuff after intubation (ETT group) and 41 patients received IV lignocaine at 1.5 mg/kg before extubation (IV group). ⋯ Results showed that there was no significant difference between the groups in terms of coughing or the hemodynamic response to tracheal extubation. In conclusion, 4% endotracheal tube cuff lignocaine was not superior to 1.5 mg/kg IV lignocaine in attenuating coughing and hemodynamic changes during extubation.

Description and first clinical application of AirWay Scope for tracheal intubation.
We have developed a novel airway apparatus, AirWay Scope, which we have used in the orotracheal intubation of 10 consecutive patients requiring general anesthesia before neurosurgical procedures. The characteristic shape of the introducer (INTLOCK), the tube guiding function and the sighting device of the AirWay Scope has possibility to facilitate tracheal intubation. Here, we report the first clinical application of this system and describe potential advantages of the apparatus.

Assessing risk factors for postoperative nausea and vomiting: a retrospective study in patients undergoing retromastoid craniectomy with microvascular decompression of cranial nerves.
We have observed that patients, after retromastoid craniectomy (RMC) with microvascular decompression (MVD) of cranial nerves, frequently experienced postoperative nausea and vomiting (PONV). The authors conducted this study to track the incidence of PONV and to identify potential factors for PONV after RMC with MVD. Medical records from 185 adults, who underwent elective RMC with MVD, were identified and reviewed from January 2000 to December 2004. ⋯ Prophylactic transdermal scopolamine patch administered preoperatively was associated with less PONV (OR=0.3, P=0.001). We concluded that PONV occurs frequently in adults recovering from RMC with MVD. The results of this study suggest that it may be necessary to administer a combination of antiemetics to decrease the incidence of PONV after RMC.
