[Propofol-ketamine versus dexmedetomidine-ketamine for sedation during upper gastrointestinal endoscopy in pediatric patients: a randomized clinical trial].
Authors: Amer AM, Youssef AM, El-Ozairy HS, El-Hennawy AM Abstract BACKGROUND AND OBJECTIVES: Day-case pediatric sedation is challenging. Dexmedetomidine is a sedative analgesic that does not induce respiratory depression. We compared dexmedetomidine to propofol when it was added to ketamine for sedation during pediatric endoscopy, regarding recovery time and hemodynamic changes. METHODS: We enrolled 120 patients (2-7 years in age) and randomly assigned them into two groups. Each patient received intravenous (IV) ketamine at a dose of 1 mg.kg-1 in addition to either propofol (1 mg.kg-1) or dexmedetomidine (0.5 ...

[A comparison of ramping position and sniffing position during endotracheal intubation: a systematic review and meta-analysis].
CONCLUSION: Our meta-analysis demonstrated that the ramping position may benefit surgical patients undergoing ETI by improving laryngeal exposure. Large-scale well-designed multicentre RCTs should be carried out to further elucidate the benefits of the ramping position in the surgical and intensive care unit patients.

CONCLUSION: The diagnosis of anaphylaxis in patients under sedation or general anesthesia may be difficult due to particularities of the perioperative context. According to the published literature, the presentation of the reaction is similar in most cases and a heightened clinical sense is key to address the situation appropriately. Finding the agent responsible for the allergic reaction is of paramount importance to prevent future episodes.

It is a disease of great significance to the anesthesiologist because it affects the neuromuscular junction. Robotic thymectomy has come up in recent times due to the minimally invasive nature and its advantages. This presents a new set of challenges for the anesthesia team, and here we present the various anesthesia considerations and perioperative management in a series of 20 patients who underwent robotic thymectomy.
