Frequent Response

Background: Increased blood pressure and heart rate are the most frequent response to laryngoscopy which sometimes causes serious complications. Laryngoscopy technique and tools modification lessen the nociceptive stimulation, thus preventing hemodynamic response. BURP maneuver is used to lower Cormack-Lehane level, but it can cause additional pain stimulation during laryngoscopy. The aim of this study was to compare the cardiovascular response and the need of BURP maneuver during laryngoscopy between CMAC® and conventional Macintosh.Methods: A randomized, single blinded, control trial was performed to 139 subjects who underwent general anesthesia with endotracheal tube. Subjects were randomised into a control group (conventional Macintosh) and an intervention group (CMAC®). The cardiovascular parameters (systolic, dyastolic, mean arterial pressure, and heart rate) were measured prior to induction (T1). Midazolam 0.05 mg/kg and Fentanyl 2 micrograms/kg were given 2 minutes before the induction. Moreover, they were given propofol 1 mg/kg followed by propofol infusion of 10 mg/kg/hour and Atracurium 0.8–1 mg/kg. After TOF-0 cardiovascular parameters (T2) were remeasured, it was proceeded to laryngoscopy. When Cormack-Lehane 1–2 was reached (with or without BURP maneuver), cardiovascular parameters were measured again (T3).Results: Unpaired T-test showed that cardiovascular response during laryngoscopy were significantly lower in the intervention group compared to the control group (p<0.05). The need of BURP maneuver was significantly lower in the CMAC® group compared to the Convensional Macintosh group (13.9% vs 40.3%; p<0.05).Conclusion: Cardiovascular response and BURP maneuver during laryngoscopy with CMAC® were significantly lower compared to conventional Macintosh.

Abstract Background Cardiac power has been suggested as the most power predictor of mortality in heart failure (HF) patients. In those patients aorta elastic properties and compensation is lost, systolic (and pulse) pressure are therefore reduced and associated with a decrease in ejection duration and pump efficiency. Cardiac rehabilitation programs have showed enhancement in cardiac performance and quality of life in HF patients. Aim Aim of this work was to evaluate the effect of high-intensity interval exercise (i.e., 30 sec at 100% of max workload, followed by 30 sec at rest, on a day-by-day 30 minutes working-out schedule for 12 weeks), on cardiac power, diastolic function indices, right ventricle performance and cardiorespiratory parameters among chronic HF patients. Methods 72 consecutive HF patients (NYHA class II-IV, ejection fraction <50%) who completed the study (exercise training group, n=33, 63±9 years, 88% men, and control group, n=39, 56±11 years, 82% men), underwent cardiopulmonary stress test, non-invasive high-fidelity tonometry of the radial artery, pulse wave velocity measurement using a SphygmoCor device, and echocardiography before and after completion of the training program. Cardiac power output (CPO) (W) was calculated as mean arterial pressure × CO/451, where mean arterial pressure = [(systolic blood pressure − diastolic blood pressure)/3] + diastolic blood pressure. Results Both groups reported similar medical characteristics and physical activity status. General mixed effects models revealed that the intervention group increased 6MWT (by 13%, p<0.05); increased cycle ergometry WRpeak (by 25%, p<0.01), showed higher O2max by 31% (p<0.001) and lower VE/VCO2 (p=0.05), whereas patients in the control group showed nosignificant changes in the aforementioned indices. Also, in the intervention group Emv/Vp was decreased by 14% (p=0.06); E to A ratio by 24% (p=0.004) and E to Emv ratio by 8% (p=0.05); while Stv increased by 25% (p=0.01). Most importantly, the intervention group reduced pulse wave velocity by 9% (p=0.05) and increased augmentation index by 26%; and VTI by 4% (p=0.05); Those parameters were not significantly changed on control group (all p>0.05). Conclusion Hight intensity exercise rehabilitation program revealed beneficial effect on left ventricular diastolic indices and right ventricle performance. As, in those patients compensation of the aorta is also lost and the LV cannot generate the extra force necessary to completely overcome the late systolic augmented pressure, the increase in the augmented pressure (AIa) observed in the intervention group reflects the benefit in aorto-ventricular coupling and cardiac power that boosts systolic pressure and restores a positive influence in pressure, like in early stages of HF.

Previous research suggests individuals with intellectual disabilities (ID) may experience autonomic dysfunction, however this has not been thoroughly investigated. PURPOSE: To compare the autonomic response to standing up (active orthostasis) and head up tilt (passive orthostasis) in individuals with ID to a control group without ID. METHODS: Eighteen individuals with and 18 individuals without ID were instrumented with an ECG-lead and finger-photoplethysmography for continuous heart rate and blood pressure recordings. The active and passive orthostasis protocol consisted of 10 minutes supine rest, 10 minutes standing, 10 minutes supine recovery, 5 minutes head-up tilt at 70 degrees, followed by 10 minutes supine recovery. The last five minutes of each position was used to calculate hemodynamic and autonomic function (time- and frequency-domain heart rate and blood pressure variability measures and baroreflex sensitivity). RESULTS Individuals with ID had higher heart rate during baseline and recovery (p<0.05), and an attenuated hemodynamic (stroke volume, heart rate) and heart rate variability response to active and passive orthostasis (interaction effect p<0.05) compared to individuals without ID. Mean arterial pressure (MAP) was higher in individuals with ID at all timepoints. CONCLUSION Individuals with ID demonstrated altered hemodynamic and autonomic regulation compared to a sex- and age-matched control group, evidenced by a higher mean arterial pressure and a reduced response in parasympathetic modulation to active and passive orthostasis.

Background There is little known whether music of different styles can directly alter blood pressure (BP) and heart rate (HR) in humans. We studied the potential effects of Bach’s orchestral Suite No. 3 in comparison to silence (S [“controls CO]) on BP and HR.Objective To analyse the effect of different music styles (intervention group) on BP, HR and C compared to S (control group).Methods 120 volunteers aged 25-75 years were randomly assigned in the intervention group (n=60) or to a control group (n=60). Interventional music styles were the different parts of Bach’s Suite No. 3, BWV 1068 [Ouverture, Air, Gavotte, Bourrée, Gigue]). Sixty healthy volunteers served as “control group” (CO): they underwent an identical study protocol but without music application.Results In studied volunteers, systolic, diastolic BP (mm Hg) and HR (min-1) decreased when Bach was played compared to CO (p<0.001). Prior to the study BPsyst was 128.3+11.3 mm Hg, BPdiast was 81.9+7.9 Hg and HR was 75.3+12.0 bpm. After sound exposure or in CO the following results were observed (table). *p<0.001, ap=0.01, bp=0.08                        BPsyst (mm Hg)                  BPdiast (mm Hg)                 HR (min-1)Ouverture        120.9+12.4*               76.9+8.8*                   69.8+11.2*Air                  121.1+12.4*               77.1+7.9*                   68.4+9.4*Gavotte           120.9+12.6*               77.0+8.9*                   68.5+9.8*Bourrée           120.6+13.7*               76.5+9.4*                   66.4+8.4*Gigue              120.4+15.2*               78.5+11.1*                 68.1+9.2*Controls          120.6+8.7a                  75.4+5.5b                    78.8+11.9*Conclusions The results provide clear evidence for the potential of Bach’ music styles to influence cardiovascular parameters. All parts of the Suite No. 3 lead to decreased values of BP and HR. In the control group we could not observe similar findings.Trial registration German Clinical Trials Register (DRKS00009835)Funding: None

Introduction Music has been proposed as a safe, inexpensive, nonpharmacological antistress intervention. The purpose of this study was to determine whether patients undergoing cataract surgery while listening to meditation music experience lower levels of blood pressure and heart rate. Methods Two hundred individuals undergoing cataract surgery participated in the study. Hundred individuals listened to meditation music, through headphones, before and during the operation (intervention group) and 100 individuals received standard care (control group). Patients stress coping skills were measured by the Sense of Coherence Scale (SOC Scale). Systolic and diastolic blood pressure and heart rate were defined as outcome measures. Results According to the SOC Scale, both groups had similar stress coping skills (mean score: 127.6 for the intervention group and 127.3 for the control group). Before entering the operating room (OR) as well as during surgery the rise in systolic and diastolic pressures was significantly lower in the intervention group ( P < 0.001). Among patients receiving antihypertensive therapy, those in the intervention group presented a lower increase only in systolic pressure ( P < 0.001) at both time recordings. For those patients in the intervention group who did not receive antihypertensive treatment, lower systolic blood pressure at both time recordings was recorded ( P < 0.001) while lower diastolic pressure was observed only during entry to the OR ( P = 0.021). Heart rate was not altered between the two groups in any of the recordings. Conclusions Meditation music influenced patients' preoperative stress with regard to systolic blood pressure. This kind of music can be used as an alternative or complementary method for blood pressure stabilizing in patients undergoing cataract surgery.

Introduction. Dysfunction of the autonomic nervous system is an important factor in the development of chronic pain. Fourth ventricle compression (CV-4) has been shown to influence autonomic activity. Nevertheless, the physiological mechanisms behind these effects remain unclear.Objectives. This study is aimed at evaluating the effects of fourth ventricle compression on the autonomic nervous system.Methods. Forty healthy adults were randomly assigned to an intervention group, on whom CV-4 was performed, or to a control group, who received a placebo intervention (nontherapeutic touch on the occipital bone). In both groups, plasmatic catecholamine levels, blood pressure, and heart rate were measured before and immediately after the intervention.Results. No effects related to the intervention were found. Although a reduction of norepinephrine, systolic blood pressure, and heart rate was found after the intervention, it was not exclusive to the intervention group. In fact, only the control group showed an increment of dopamine levels after intervention.Conclusion. Fourth ventricle compression seems not to have any effect in plasmatic catecholamine levels, blood pressure, or heart rate. Further studies are needed to clarify the CV-4 physiologic mechanisms and clinical efficacy in autonomic regulation and pain treatment.

Background: Conclusions/Importance.Indicators of hypertension can be seen through the blood pressure (BP) and heart rate (HR). Several attempts continue to be made to control BP and HR, such as progressive muscle relaxation (PMR) and slow deep breathing(SDB). Objectives:The purpose of this study was to analyze the effect of PMR and SDB to control BP and HR on the hypertension clients. Methods: The research utilized a quasi-experimental design with pre-post test nonequivalent control group. Sample of 91 respondents were selected during May-July 2016 through convenience sampling techniques. The researcher used parametric statistical regression multiple linear regression to analyze the effect of PMR, SDB, and combination of PMR and SDB on BP and HR. Results: In the intervention group, PMR, SDB, and combined PMR-SDB are given twice a day for four days. The results showed the influence of PMR,SDB,combinedPMR-SDBtechniquestoBPandHR(p<0.05).PMRandcombined techniques (PMR-SDB) simultaneously and partially have a significant influence on BP and HR (p<0.05). SDB simultaneously only have a significant influence on diastolic BP and HR (p<0.05), but partially have a significant influence on BP and HR (p<0.05). Conclusions: The research concluded that there is significant influence of PMR, SDB, and combined PMR and SDB on BP and HR. PMR and SDB programs need to be developed as independent nursing interventions on the nursing care of patients with hypertension.

The Impact

Contemplative practices promote well-being, work engagement and resilience among health care providers. We examined the impact of The Pause, a brief contemplative intervention, on health care providers’ physiological stress response. Participants were randomly assigned to either The Pause or the control group. They participated in a high-fidelity, stressful medical simulation. Following the simulation, intervention group practiced The Pause. Outcome measures were heart rate variability, heart rate, and blood pressure. We adjusted for baseline physiological variables, sociodemographic variables, self-care practices, and perceived stress. Participants in the intervention group had a standard deviation of the normal-to-normal RR intervals (heart rate variability indicator) that was 13.8 (95% CI 4.0, 23.5; p < .01) points higher than those in the control group. There were no significant effects of The Pause on heart rate or blood pressure. The Pause may reduce stress reactivity, increase heart rate variability, and enhance resilience in health care providers.

Background: Brain injuries are a major cause of mortality and disability. Sensory stimulation can reduce the complications of brain injuries in the patients. Objectives: To compare the effect of foot reflexology with tactile stimulation of the hand on level of consciousness and physiological indicators in traumatic brain injury (TBI) patients Materials & Methods: 60 TBI patients hospitalized in the ICU of selected hospitals in Qazvin, Iran assigned to three intervention groups and one control group using block randomization. The patients were matched using the glasgow coma scale (GCS) (score of 8) and the Richmond agitation and sedation scale (RASS) (scores -2 to +2). The first intervention group received tactile stimulation of the hand from the wrist downwards, the second intervention group received foot reflexology, and the third both tactile stimulation and foot reflexology, while the controls received routine care. The Data collected were analyzed in SPSS V. 21. P<0.05 was set as the level of statistical significance. Results: The Mean±SD level of consciousness was the highest in the foot reflexology group(9.38±3.3) compared to that in the group of tactile stimulation of the hand (9.03±2.18), the group receiving both treatments (7.96±1.8) and the control group (6.92±3.3) (P<0.001). The findings also revealed reductions in the heart rate, respiratory rate and systolic blood pressure and increases in peripheral capillary oxygen saturation (O2 sat) and level of consciousness in the TBI of the foot reflexology group. Conclusion: Foot reflexology can decrease the heart rate, respiratory rate and systolic blood pressure, and increase O2 sat in TBI patients and increase the level of consciousness.

BackgroundGiven the anxiety patients experience during angiography, evidence supporting the efficacy of music therapy during these angiographic procedures is potentially of clinical value.ObjectiveTo analyze the existing literature forthe use of music therapy during cerebral, coronary, and peripheral angiography to determine whether it improves patient anxiety levels, heart rate, and blood pressure during the procedure.MethodsPubMed, Embase, and Scopus were searched to identify studies of interest. Inclusion criteria included studies reporting using music therapy in either cerebral, coronary, or peripheral angiography. Studies focused on a pediatric population; animal studies and case reports were excluded. Participant demographics, interventions, and outcomes were collected by two study authors. Bias and study quality of randomized controlled trials (RCTs) were assessed using the Cochrane Risk of Bias Tool. Separate meta-analyses of the RCTs were performed to compare State Trait Anxiety Inventory (STAI), heart rate (HR), and systolic and diastolic blood pressure (SBP and DBP) in the music intervention group versus control group. Heterogeneity was determined by calculating I2 values, and a random-effects model was used when heterogeneity exceeded 50%.ResultsThe preprocedure to postprocedure improvement in STAI was significantly greater in the experimental group than the control group (p=0.004), while the decrease in HR, SBP, and DBP was not significant.ConclusionsRecorded music and/or music therapy in angiography significantly decreases patients’ anxiety levels, while it has little to no effect on HR and BP. This meta-analysis is limited by the relatively few RCTs published on this subject.PROSPERO registration numberCRD42018099103
