Introduction: Sedative premedication is the mainstay of pharmacological therapy in children undergoing surgeries. This study compares preoperative melatonin, clonidine, and dexmedetomidine on sedation, ease of anesthesia induction, emergence delirium, and analgesia.
Materials And Methods: One hundred and five children, 3-8 years, either sex, ASA I/II, posted for infraumbilical surgery, randomized to receive clonidine 5 mcg/kg (Group C), dexmedetomidine 3 mcg/kg (Group D), and melatonin 0.2 mg/kg (Group M) 45 minutes before surgery. Preoperative Sedation/Anxiety and Child-Parent Separation Score (CPSS) were assessed. Identical anesthesia technique was utilized. Emergence delirium (Watcha score) and postoperative pain (Objective Pain Scale score) were monitored postoperatively.
Results: Patients were demographically comparable. Sedation score >Grade 3 was absent. Grades 1/2/3 were present in 10/19/6 (Group C), 2/26/7 (Group D), and 7/26/2 (Group M). Grade 1 CPSS was present in 42.6% (Group C), 37.1% (Group D), and 28.6% (Group M). Pediatric Anesthesia Behavior Score (PABS) was comparable between Groups C and D (p = 0.224; 95% CI -0.090 to 0.604) and Groups C and M (p = 0.144; 95% CI -0.633 to 0.061) while PABS was better in Group D compared to Group M (p = 0.0007; 95% CI -0.890 to -0.195). Watcha scores were 33/2/0/0 (Group C), 34/1/0/0 (Group D), and 32/2/1/0 (Group M) immediately after extubation. Scores were 31/4/0/0 (Group C), 33/2/0/0 (Group D), and 31/4/0/0 (Group M) at 30 minutes and 28/7/0/0 (Group C), 29/6/0/0 (Group D), and 24/11/0/0 (Group M) at 1 hour. The scores were comparable (p > 0.05). Objective Pain Scale scores were comparable between Groups C and D and Groups C and M (p > 0.05). Lower scores were present in Group D compared to M (p = 0.023).
Conclusion: Melatonin, clonidine, and dexmedetomidine are efficacious for producing preoperative sedation, reducing anxiety, postoperative pain, and emergence delirium.

Effect of Capromorelin on Appetite and Weight Gain of Domestic Pigeons ().

Weight loss and decreased appetite are commonly encountered sequela of disease and stress in avian patients. However, there is currently minimal information in the veterinary literature regarding appetite stimulation in birds. Capromorelin is a potent agonist of the growth hormone secretagogue receptor and increases food consumption via direct stimulation of the hunger centers of the hypothalamus.

Background: The results of ablation of sustained monomorphic ventricular tachycardia (SMVT) are suboptimal. For many patients with implantable cardioverter-defibrillators (ICDs), ICD electrograms (ICD-EGs) provide the only available information on SMVT. ICD-EGs have the ability to distinguish morphologically distinct SMVT and can be used for pace mapping.

Background: Prospective data on the clinical course of the ascending thoracic aorta are lacking.
Objectives: This study sought to estimate growth rates of the ascending aorta and to evaluate occurrences of adverse aortic events (AAEs)-that is, thoracic aortic ruptures, type A aortic dissections, and thoracic aortic-related deaths.
Methods: In this prospective cohort study from the population-based, multicenter, randomized DANCAVAS (Danish Cardiovascular Screening trials) I and II, participants underwent cardiovascular risk assessments including electrocardiogram-gated, noncontrast computed tomography (CT) scans.
