Heart Rate Variability in Surgical Patients Experiencing Live Bedside Music; An Explorative Study.

It's known that surgery elicits a stress response involving the autonomic nervous system (ANS) which is important in general recovery but can also have detrimental effects in older patients. Music seems to positively effect postoperative recovery, although the mechanism requires further unravelling. Our objective was to explore the response of the ANS to live bedside music in older surgical patients, by using heart rate variability (HRV) as a proxy. This explorative prospective non-randomized controlled cohort study included 101 older non-cardiac surgical patients, with a median age of 70 (range 60-88 years). HRV was measured in a cohort receiving live bedside music provided by professional musicians and in a control group that did not receive music. HRV was measured pre-intervention, during the intervention, 30 min after the intervention, and again after three hours. Mixed linear modelling was used to assess the effect of the intervention compared to the control group over time. A significant change in both the low and high frequency bands (p = 0.041) and (p = 0.041) respectively, was found over time in the music group compared to the control group indicating relaxation and increased parasympathetic activity in the music group. Other measures revealed a trend but no significant effect was shown. These results provide a first glance and contribute to a better understanding of the effect of music on the recovery of older surgical patients.

Live bedside music in daily clinical practice of a surgical hospital ward among older patients: A controlled study design of an innovative practice.

OBJECTIVE: There is an increasing interest in the role of the arts, particularly music, in healthcare. Music seems an attractive non-pharmacological intervention for older patients to improve postoperative outcomes. Although live music elicits more meaningful responses from an audience than recorded music, the use of live music is still rare on hospital wards. In view of the positive effects of recorded music on older surgical patients, we designed, in collaboration with a conservatoire, an innovative practice named Meaningful Music in Health Care (MiMiC). The aim is to determine whether live bedside music implements into daily practice and allows improves patient outcomes. METHOD: This manuscript provides an overview of a trial evaluating if live bedside music can improve postoperative outcomes in older patients. The MiMiC initiative is a non randomized controlled trial study among older surgical patients on three hospital wards. Live bedside music is performed by professional musicians, once a day for six or seven consecutive days. The primary outcome is experienced pain; secondary outcomes are anxiety, relaxation and physical parameters (heart rate, heart rate variability, blood pressure, respiratory rate and oxygenation). Measurements of these variables are collected before the intervention, 30 min afterwards and again after three hours. Daily evaluations determine whether this innovative practice can be implemented in daily practice. CONCLUSION: This manuscript describes a new practice, live bedside music by professional musicians, on surgical hospital wards aiming to improve patient outcomes. It offers a new field of interprofessional collaboration for the benefit of patients. Further research must be conducted focussing on patient outcomes, including cost-effectiveness and the experiences of patients and healthcare professionals.

The effect of music on postoperative recovery in older patients: A systematic review.

OBJECTIVE: Surgery is an important part of the treatment modalities offered to older patients with cancer. Natural ageing processes lead to deterioration of organ function, making older patients more vulnerable and at risk for experiencing less-favourable outcomes and complications after surgery. Non-pharmaceutical interventions, such as music, may be preferable to medical interventions in older people, who are at risk for adverse effects and drug interactions due to altered physiology and drug metabolism. We aimed to assess the effect of music on postoperative recovery in older patients and to determine the underpinning theoretical models MATERIALS AND METHODS: This systematic review used the databases PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsychINFO, and Répertoire International de Littérature Musicale (RILM). Clinical studies published, until 2015, investigating music as a single intervention for hospitalised patients postoperative, population mean age 60 years or older were selected. All types of postoperative music interventions, consisting of single or more sessions, which take place at a hospital ward. All patient outcomes were included. The search and screening was performed twice, independently, and seventeen articles were finally selected. RESULTS: Four theoretical models were detected underpinning the effect of music on postoperative recovery. The way the music interventions were shaped, varied strongly. Therefore it remained unclear what is the most effective way of performing the music in the postoperative period. Although evidence is still limited, results do show that music has a positive effect on the recovery of older patients after surgery. Pain and anxiety are reduced, and relaxation, cognitive functioning, and patient satisfaction increase during postoperative recovery. No negative side effects of music as an intervention were found and therefore seems a non-harming and non-invasive intervention. CONCLUSION: It seems worthwhile to further explore live music making in music interventions with older hospitalised surgical patients.

Pre-clinical patient contacts and the application of biomedical and clinical knowledge.

CONTEXT: Real-patient contacts in problem-based undergraduate medical education are promoted as a good way to introduce biomedical and (in)formal clinical knowledge early in the curriculum and thereby to foster the development of coherent and integrated knowledge networks. There are concerns, however, that such contacts may cause students to focus on clinical knowledge to the neglect of biomedical knowledge, and that group discussions may be dominated by teachers. We examined these concerns by addressing the following questions in the context of group sessions in which students prepare for and report on real-patient contacts. To what extent are biomedical and (in)formal clinical knowledge addressed? To what extent are these knowledge types addressed by students or tutors? Are connections made between biomedical and clinical knowledge? METHODS: We videotaped and transcribed six preparation and six reporting group sessions (two preparation and two reporting phases for each of three groups) held with students in Year 3 of the problem-based curriculum at Maastricht University. During this year, real patients rather than paper patients are used. Qualitative analysis software was used to code propositions in the transcriptions in order to identify different kinds of knowledge and different functions of biomedical knowledge. RESULTS: Formal clinical knowledge was the subject of 40.7% and 34.8% of propositions during the preparation and reporting phases, respectively. The corresponding percentages for biomedical knowledge were 15.0% and 28.0%. Tutors accounted for 63.4% of propositions during the preparation phase, and students for 80.1% during the reporting phase. Nearly all biomedical knowledge was related to clinical knowledge. CONCLUSIONS: It appears that pre-clinical patient encounters can stimulate students to pay attention to both clinical and biomedical knowledge and to how they are connected. Tutor dominance was evident only during the preparation phase. Further research is needed to investigate whether pre-clinical patient contacts promote the development of coherent and integrated knowledge networks.

Protection against early intestinal compromise by lipid-rich enteral nutrition through cholecystokinin receptors.

OBJECTIVE: Early gut wall integrity loss and local intestinal inflammation are associated with the development of inflammatory complications in surgical and trauma patients. Prevention of these intestinal events is a potential target for therapies aimed to control systemic inflammation. Previously, we demonstrated in a rodent shock model that lipid-rich enteral nutrition attenuated systemic inflammation and prevented organ damage through a cholecystokinin receptor-dependent vagal pathway. The influence of lipid-rich nutrition on very early intestinal compromise as seen after shock is investigated. Next, the involvement of cholecystokinin receptors on the nutritional modulation of immediate gut integrity loss and intestinal inflammation is studied. DESIGN: Randomized controlled in vivo study. SETTING: University research unit. SUBJECTS: Male Sprague-Dawley rats. INTERVENTIONS: Liquid lipid-rich nutrition or control low-lipid feeding was administered per gavage before hemorrhagic shock. Cholecystokinin receptor antagonists were used to investigate involvement of the vagal antiinflammatory pathway. MEASUREMENTS AND MAIN RESULTS: Gut permeability to horseradish peroxidase increased as soon as 30 mins postshock and was prevented by lipid-rich nutrition compared with low-lipid (p<.01) and fasted controls (p<.001). Furthermore, lipid-rich nutrition reduced plasma levels of enterocyte damage marker ileal lipid binding protein at 60 mins (p<.05). Early gut barrier dysfunction correlated with rat mast cell protease plasma concentrations at 30 mins (rs=0.67; p<.001) and intestinal myeloperoxidase levels at 60 mins (rs=0.58; p<.05). Lipid-rich nutrition significantly reduced plasma rat mast cell protease (p<.01) and myeloperoxidase (p<.05) before systemic inflammation was detectable. Protective effects of lipid-rich nutrition were abrogated by cholecystokinin receptor antagonists (horseradish peroxidase; p<.05 and rat mast cell protease; p<.05). CONCLUSIONS: Lipid-rich enteral nutrition prevents early gut barrier loss, enterocyte damage, and local intestinal inflammation before systemic inflammation develops in a cholecystokinin receptor-dependent manner. This study identifies activation of the vagal antiinflammatory pathway with lipid-rich nutrition as a potential therapy in patients prone to develop a compromised gut.

Effect of dietary inulin supplementation on inflammation of pouch mucosa in patients with an ileal pouch-anal anastomosis.

PURPOSE: Inflammation is a constant finding in the ileal reservoir of patients with an ileal pouch-anal anastomosis and is associated with decreased fecal concentrations of the short chain fatty acid butyrate, increased fecal pH, changes in fecal flora, and increased concentrations of secondary bile acids. In healthy subjects, inulin, a dietary fiber, is fermented to short chain fatty acids and leads to a lower pH and potentially beneficial changes in fecal flora. The aim of the present study was to investigate the effect of enteral supplementation of inulin on inflammation of the ileal reservoir. METHODS: Twenty patients received 24 g of inulin or placebo daily during three weeks in a randomized, double-blind, crossover design. Stools were analyzed after each test period for pH, short chain fatty acids, microflora, and bile acids. Inflammation was assessed endoscopically, histologically, and clinically. RESULTS: Compared with placebo, three weeks of dietary supplementation with 24 g of inulin increased butyrate concentrations, lowered pH, decreased numbers of Bacteroides fragilis, and diminished concentrations of secondary bile acids in feces. This was endoscopically and histologically accompanied by a reduction of inflammation of the mucosa of the ileal reservoir. CONCLUSION: Enteral inulin supplementation leads to a decrease of inflammation-associated factors and to a reduction of inflammation of pouch mucosa.
