Background: Dexmedetomidine, an alpha-2 agonist, has been used for attenuation of hemodynamic response to laryngoscopy but not through the nebulized route. We evaluated the effects of preoperative dexmedetomidine nebulization on the hemodynamic response to laryngoscopy and intubation and examined the intraoperative anesthetic-analgesic requirements and recovery outcomes. Methods: Overall, 120 ASA I & II adult patients (of either gender) undergoing elective surgeries and requiring tracheal intubation, were randomized to receive nebulized dexmedetomidine (1 µg/kg in 3–4 ml of 0.9% saline) or 0.9% saline (3–4 ml), 30 min before anesthesia induction. Heart rate and non-invasive systolic blood pressure were monitored for 10 min following laryngoscopy. Results: After laryngoscopy, linear mixed effect modelling showed significantly lower trend of increase in heart rate in the dexmedetomidine group versus saline (P = 0.012); however, there was no difference in the systolic blood pressure changes between the two groups (P= 0.904). Induction dose of propofol (P < 0.001), intraoperative fentanyl consumption (P = 0.007), and isoflurane requirements (P = 0.013) were significantly lower in the dexmedetomidine group. There was no difference in the 2-h incidence of postoperative nausea and vomiting (PONV) (P = 0.612) or sore-throat (P = 0.741).Conclusions: Nebulized dexmedetomidine at 1 µg/kg attenuated the increase in heart rate but not systolic blood pressure following laryngoscopy and reduced the intraoperative anesthetic and analgesic consumption. There was no effect on early PONV, sore-throat, or increase in incidence of adverse effects. Nebulized dexmedetomidine may represent a favorable alternative to the intravenous route in short duration surgeries.

Background: Subanesthetic intravenous (IV) ketamine acts as an analgesic and has opioid-sparing effects, particularly for acute postoperative pain; however, its effectiveness in children is understudied. The primary aim of this study was to evaluate the non-inferiority of subanesthetic IV ketamine vs. caudal bupivacaine for postoperative analgesia in children undergoing infraumbilical surgery.Methods: Children aged < 6 years were enrolled in this single-blind study and randomized to receive either subanesthetic IV ketamine (0.3 mg/kg) or caudal 0.125% bupivacaine (1 ml/kg) along with general anesthesia. Postoperative pain was assessed using the FLACC scale at 30 minutes and 1, 2, 3, and 6 h post-operation. Intra- and postoperative opioid consumption, time to extubation, postoperative vomiting, agitation, sedation, and inflammatory markers were also assessed.Results: Altogether, 141 children completed the study (ketamine group: n = 71, caudal group: n = 70) The cumulative proportion of children without significant postoperative pain (FLACC score < 4) in the first 6 h post-surgery was 45.1% in the ketamine group vs. 72.9% in the caudal group (P < 0.001). More children in the ketamine group required an additional dose of intraoperative fentanyl (33.8% vs. 5.7%, P < 0.001) and postoperative tramadol (54.9% vs. 27.1%, P < 0.001). However, postoperative agitation, sedation, and other secondary outcomes were similar between the groups.Conclusions: Subanesthetic ketamine is inferior to caudal bupivacaine for postoperative analgesia in children aged < 6 years undergoing infra-umbilical surgeries; however, other postoperative outcomes are similar.
