Use of Dexmedetomidine versus Nitroglycerine to Provide Hypotensive Anesthesia in ENT Surgeries (Functional Endoscopic Sinus Surgery).

The article presents multiple clinical studies focused on anesthesia, sepsis biomarkers, and patient awareness of drug interactions. One study compares intrathecal nalbuphine and fentanyl as adjuvants to bupivacaine for postoperative analgesia after cesarean section, finding nalbuphine provides longer analgesia with fewer side effects. Another study evaluates procalcitonin (PCT) and red cell distribution width (RDW) as early diagnostic and prognostic biomarkers in sepsis and septic shock, identifying specific cutoff values associated with mortality risk. A third study compares dexmedetomidine and nitroglycerin for induced hypotensive anesthesia during functional endoscopic sinus surgery (FESS), concluding both are effective but dexmedetomidine offers better hemodynamic stability and fewer postoperative complications. Additionally, a cross-sectional study reveals poor awareness among oncology patients receiving capecitabine about food and supplement interactions, highlighting the need for improved patient education.
