Intubating Laryngeal Mask Airway (ILMA) is a relatively new device designed to have better intubating characteristics than the standard Laryngeal Mask Airway. This study was designed to compare Intubating Laryngeal Mask with standard Direct Laryngoscopy (DLS), taking into account ease of intubation, time taken for intubation, success rate of intubation, hemodynamic responses and upper airway morbidity. ⋯ DLS is comparatively a faster method to secure tracheal intubation than Intubating Laryngeal Mask. ILMA offers no advantage in attenuating the hemodynamic responses compared to direct laryngoscope. The success rate of intubation through Intubating Laryngeal Mask is comparable with that of DLS. The upper airway morbidity and mean oxygen saturation are comparable in both the groups.

Hemodynamic responses of laryngoscopy, intubation, and pain are powerful noxious stimulus which should be attenuated by the appropriate premedication, smooth induction, and rapid intubation. ⋯ Oral pregabalin premedication effectively leads to sedation and analgesia with successful attenuation of the adverse and deleterious hemodynamic pressor response.

A comparative study was carried out to evaluate the analgesic efficacy and side effects of addition of fentanyl to local anesthetic undergoing surgeries on forearm and elbow. All patients were hemodynamically stable, and there were no serious side effects in any of the patients in both the groups. The difference in the mean duration of analgesia between the groups was statistically significant (P<0.01). So we can conclude- Addition of Fentanyl to local anaesthetic in brachial plexus block increases duration of analgesia. ⋯ This study has shown that the mean duration of analgesia is extended if fentanyl is added to local anesthetics, without increasing the side effects.

Global warming refers to an average increase in the earth's temperature, which in turn causes changes in climate. A warmer earth may lead to changes in rainfall patterns, a rise in sea level, and a wide range of impacts on plants, wildlife, and humans. Greenhouse gases make the earth warmer by trapping energy inside the atmosphere. ⋯ The global warming potential (GWP) of a halogenated anesthetic is up to 2,000 times greater than CO2. Global warming potentials are used to compare the strength of different GHGs to trap heat in the atmosphere relative to that of CO2. Here we discuss about the GWP of anesthetic gases, preventive measures to decrease the global warming effects of anesthetic gases and Xenon, a newer anesthetic gas for the future of anesthesia.

Ensuring adequate preoperative sedation and anxiolysis is essential, especially in pediatric surgery. Various drugs and routes of administration have been evaluated to determine the optimal method of sedation. ⋯ We conclude that either drug may be used with ease in preschool children undergoing elective surgery.
