This study was to identify the safety and efficacy of adding epidural N-methyl-D-aspartate receptor antagonists (ketamine) to oral gabapentin for the treatment of post spinal cord injury-related chronic pain. ⋯ Epidurally administrated ketamine seems to be a safe adjunct to gabapentin in post spinal cord injury-related chronic pain. However, its analgesic efficacy was limited to 30 days after injection.

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.

Ketamine-induced hemodynamic pressor response and psychomimetic effects should be attenuated by appropriate premedication. The present study was designed to evaluate the clinical efficacy and safety of dexmedetomidine premedication for balancing the ketamine-induced hemodynamic pressor response and psychomimetic effects. ⋯ The dexmedetomidine premedication effectively attenuated the ketamine induced hemodynamic pressor response and post-anesthetic delirium effects.
