  • Maximal Expiratory Pressure and valsalva manoeuvre do not produce similar cardiovascular responses in healthy men
    Experimental Physiology, 2016

    Abstract:

    New Findings What is the central question of this study? This is the first study to evaluate and describe the cardiovascular responses during Maximal Expiratory Pressure compared with the Valsalva manoeuvre, and whether those responses are similar. What is the main finding and its importance? This study showed that the duration of the manoeuvres appears to be responsible for the different physiological mechanisms involved in the cardiovascular responses to each manoeuvre and that the intensity of Expiratory effort was related to the response in Maximal Expiratory Pressure. These results are important to identify the risks to which subjects are exposed when performing these manoeuvres. The main purpose of this study was to compare the cardiovascular responses between the Valsalva manoeuvre (VM) and Maximal Expiratory Pressure (MEP) and to evaluate the effect of age on these responses. Twenty-eight healthy men were evaluated and divided into two groups, younger (n = 15, 25 ± 5 years) and middle aged (n = 13, 50 ± 5 years), and they performed the VM and MEP measurement. The VM consisted of an Expiratory effort (40 mmHg) against a manometer for 15 s, and the MEP was performed according to American Thoracic Society guidelines. The cardiovascular responses were analysed at rest, isotime (3 s), peak, nadir and recovery, and the cardiovascular variations (Δ) were calculated as peak or isotime minus resting values. For the statistical analysis, we used two-way ANOVA (P   0.05), but MEP presents higher values for mean arterial Pressure (MAPPeak, MAPIsotime, ΔMAP and ΔMAPIsotime) than those observed in the VM (P < 0.05). The execution time of the manoeuvres (VM ∼15 s and MEP ∼5 s) appears to be largely responsible for the activation of different physiological mechanisms involved in the cardiovascular control for each manoeuvre, and the intensity of Expiratory effort is related to the higher response of MAP and peripheral vascular resistance (PVRIsotime and ΔPVRIsotime) during MEP (P < 0.05). Moreover, it appears that age affects only the heart rate and PVR responses (P < 0.05), which were higher in the young and middle-aged group, respectively. Based on these findings, we can conclude that MEP and the VM do not generate similar cardiovascular responses, except for cardiac output.

  • Cardiovascular responses to Maximal Expiratory Pressure and valsalva maneuver in healthy men
    European Respiratory Journal, 2012
    Co-Authors: Vinicius Minatel, Audrey Borghi-silva, Marlus Karsten, Amanda Tiemi Shimojo, Isabella Gracindo Pissinato, Aparecida Maria Catai
    Abstract:

    Background/Aim: The respiratory assessment, mainly the measure of Maximal Expiratory Pressure (MEP), has some contraindications because of similarity with the Valsalva maneuver (VM). The objective of this study was evaluated the cardiovascular responses during MEP and identify if this measure reproduces the responses obtained in VM. Methods: 19 healthy men participated in this study, 11 young (23±3 years) and 8 middle-age (45±3 years), divided in two groups – G1 and G2, respectively. They performed the VM (3x) with 40mmHg of oral Pressure during 15s, at the sitting position using different mouthpieces (one with a leak of 2mm and another without). The MEP (5x) was performed from total lung capacity, according ATS/ERS in the same conditions of VM. We analyzed during VM and MEP: the heart rate variation (ΔHR) and systolic and diastolic blood Pressure variation (ΔSBP, ΔDBP), and the MEP and Valsalva index (MEPI, VI).

ANOVA three-way with Holm-Sidak post-hoc test (p<0.05) was employed to analyses de effect of maneuvers, groups and mouthpiece. Results: We observed that VM have values of ΔSBP (VM: 11±8 mmHg; MEP: 6±6 mmHg), ΔHR (VM: 40±11 bpm; MEP: 22±6 bpm) and indexes (IV: 2.0±0.4; IMEP: 1.5±0.2) were bigger than MEP (p<0.05), independent of the group or the mouthpiece. When we analyzed the groups influence we observed that G2 have higher values of ΔSBP and ΔDBP than G1 (p<0.05), but not to VI and MEPI (p=0.001). The mouthpiece effect was observed only in ΔDBP (p=0.006) and the piece without leak had the biggest values. Conclusion: At the studied condition the MEP does not reproduce the cardiovascular responses observed in VM in healthy men. Financial support: CNPq, FAPESP.

    Abstract:

    s / Autonomic Neuroscience: Basic and Clinical 163 (2011) 1–133 46 per day to achieve the goal BP. The repeat estimation of BRS was performed in 6 months of treatment. Results: At baseline spontaneous BRS in RHTN was significantly lower compared to controls (5.61±0.08 vs 6.60±0.10 ms/mm Hg; P<0.05). Inhypertensive patients baseline spontaneousBRSnegatively correlated with the mean 24 hour SBP (r=−0.48; P=0.02) and mean 24 hour DBP (r=−0.44; P=0.04) BP at baseline. Hypertensive patients were subdivided on two groups: who took spironolactone 25 mg per day (group 1, n=26) andwho took spironolactone 50 mg per day (group 2, n=8). SpontaneousBRSatbaselinewas similar inbothgroups. In “high” spironolactone dose patients final 24 hour SBP and 24 hour DBP were lower than similar values in “low” dose spironolactone patients (126± 3/83±2 vs 134±4/89±1 mm Hg; P<0.01). In patients of group 2 the final BRS was higher compared with patients of group 1 (6.30±0.07 vs 5.80±0.08 ms/mm Hg; P<0.05). The negative correlations of BRS delta with SBP delta (r=−0.53; P=0.02) and DBP delta (r=−0.44; P<0.05) were observed only in patients of group 2. Conclusion: In patients with RHTN, spontaneous BRS is decreased and is negatively associated with the level of BP. Combinative antihypertensive treatment with spironolactone improves spontaneous BRS in patients with RHTN.

  • Isokinetic muscle strength after thoracotomy: standard vs. muscle-sparing posterolateral thoracotomy.
    The Thoracic and Cardiovascular Surgeon, 2010
    Co-Authors: Sedat Ziyade, A. Baskent, Serhan Tanju, Alper Toker, Sukru Dilege
    Abstract:

    The aim of the study was to compare the effects of conventional posterolateral thoracotomy and muscle-sparing posterolateral thoracotomy on pulmonary and muscle strength. From January 2003 to December 2004, 50 randomized patients with a diagnosis of primary lung cancer underwent pulmonary resection. The patients were divided into two groups: Group I (n=25) underwent conventional posterolateral thoracotomy, while Group II (n=25) had muscle-sparing thoracotomy. The groups were compared in terms of shoulder abduction/adduction isokinetic muscle strength and respiratory muscle strength. A comparison of Maximal Expiratory Pressure and Maximal inspiratory Pressure preoperatively and postoperatively and of Maximal Expiratory Pressure and Maximal inspiratory Pressure preoperatively and at 3 months postoperatively showed statistically significant differences (P<0.05). For the preservation of muscle strength, especially in patients whose jobs involved manual work, muscle-sparing posterolateral thoracotomy should be the first choice rather than conventional thoracotomy. Moreover, if necessary, the latissimus dorsi muscle can be used more extensively as a flap after muscle-sparing posterolateral thoracotomy procedures.

    Abstract:

    Background: This study aims to investigate the acute effects of manual therapy on pain perception and respiratory parameters in patients with thoracic outlet syndrome. Methods: The study included 10 patients with thoracic outlet syndrome (1 male, 9 females; mean age 31.3±9.0 years; range, 20 to 43 years). Patients were accepted in a single session of manual therapy involving the cervical spine and thorax. Stretching of scalene, upper trapezius, sternocleidomastoid, rectus abdominis, hip flexor muscles; and mobilization of first rib, cervical and thoracic spine, sacroiliac joints and thorax were applied as manual therapy program. Pain perceptions of upper arm and neck were assessed with visual analog scale. Measurements were performed before and immediately after of a 30-minute session of manual therapy. Pulmonary function testing was performed with a spirometer. Respiratory muscle strength (inspiratory and Expiratory muscle strength, Maximal inspiratory Pressure and Maximal Expiratory Pressure, respectively) was measured. Respiratory muscle endurance was recorded using sustained threshold loading of 35% Maximal inspiratory Pressure. Results: There were no significant changes in any pulmonary function parameters or Maximal Expiratory Pressure following manual therapy intervention (p>0.05). However, Maximal inspiratory Pressure and respiratory muscle endurance improved (p
