Background The operating room can be a frightening environment for paediatric patients. This study investigated whether music medicine can mitigate preoperative anxiety in children. Materials and methods One hundred and fifty children undergoing general anaesthesia were randomised to listen to music of the child’s choice, lullaby music or no music before induction. Heart rates were measured in the waiting room, upon first entry into the operating room and just prior to induction. Results There was no significant difference in average heart rate change from the waiting room to induction in the patient choice, lullaby and control groups. Older age was associated with higher heart rate changes between baseline and entering the operating room. Pharmacologic sedation showed a significant beneficial effect on heart rate change at induction. Conclusion Use of music medicine in the operating room does not show efficacy to reduce anxiety in children based on heart rate changes.

Abstract Background The prognostic impact of heart rate (HR) in acute heart failure (AHF) patients is not well known especially in atrial fibrillation (AF) patients. Purpose The aim of the study was to evaluate the impact of admission HR, discharge HR, HR difference (HRD) (admission- discharge) in AHF patients with sinus rhythm (SR) or AF on long- term outcomes. Methods We included 1398 patients consecutively admitted with AHF between October 2013 and December 2014 from a national multicentric, prospective registry. Logistic regression models were used to estimate the association between admission HR, discharge HR and HR difference and one- year all-cause mortality and HF readmission. Results The mean age of the study population was 72±12 years. Of these, 594 (42.4%) were female, 655 (77.8%) were hypertensive and 655 (46.8%) had diabetes. Among all included patients, 745 (53.2%) had sinus rhythm and 653 (46.7%) had atrial fibrillation. Only discharge HR was associated with one-year all-cause mortality (Relative risk (RR)= 1.182, confidence interval (CI) 95% 1.024–1.366, p=0.022) in SR. In AF patients discharge HR was associated with one-year all-cause mortality (RR= 1.276, CI 95% 1.115–1.459, p≤0.001). We did not observe a prognostic effect of admission HR or HRD on long-term outcomes in both groups. This relationship is not dependent on left ventricular ejection fraction (Figure 1) Effect of post-discharge heart rate Conclusions In AHF patients lower discharge HR, neither the admission nor the difference, is associated with better long-term outcomes especially in AF patients Acknowledgement/Funding Heart Failure Program of the Red de Investigaciόn Cardiovascular del Instituto de Salud Carlos III, Madrid, Spain (RD12/0042) and the Fondo Europeo de

Mean Heart Rate

Four dogs were given discriminative conditioning using 3 CSs. One CS (CS + C) was always reinforced with shock, another (CS−) was never reinforced while a third (CS + U) was reinforced 75% of the trials with reinforcement occurring either immediately, 2 or 4 sec. after the termination of CS. Heart-rate change was greater for CS + C than for CS + U or CS there was no significant difference between the latter. The termination of the CS + U appeared to be informative; mean heart rate during the post-CS period on unreinforced trials of CS + U was not significantly different from that during CS + C. Flexion latencies were longer to CS + U. The cardiac UR was less for CS + U than for CS + C, suggesting that temporal uncertainty inhibits the UR.
