“…16,18 In our study neither systolic nor diastolic pressure were significantly different between the three groups in response to exercise, with or without NMES treatment. However, in the comparison between exercise phases, significant differences for systolic and diastolic pressures were found.…”

“…However, the group of patients with spinal cord injury above the T6 level presented an increased risk of comorbidity and morbidity. 16 Manogue et al, 17 in a recent review have noted that both acute and chronic SCIs are often followed by cardiac abnormalities, characterized by impairment of the Sympathetic Nervous System, with dominance of the Parasympathetic counterpart. Episodes of bradycardia, sinus arrest or total heart block are observed in the acute phase.…”

“…It is known that individuals with acute or chronic SCI exhibit cardiac impairment due to the lack of harmonization within the autonomic nervous system, especially when patients with a neurological level above T6 are considered, 14,16,18 suggesting the presence of a compensated sympathetic impairment. 16,18 In our study neither systolic nor diastolic pressure were significantly different between the three groups in response to exercise, with or without NMES treatment.…”

OBJECTIVE:To identify changes in blood pressure and heart rate in individuals with chronic paraplegia undergone neuromuscular electrical stimulation treatment. METHOD: Design: Observational prospective. Participants: Twenty individuals with chronic paraplegia (neurological level above T6) belonging to two different groups (G1 and G2) were submitted to an upper limb exercise test. G1 patients (n=13) had been treated with neuromuscular electrical stimulation (25Hz, pulses of 300μs, 100V) for 2 years or more, at least once a week; G2 patients (n=7) did not receive neuromuscular electrical stimulation treatment; G3 individuals (n=6) were healthy volunteers. Procedures: Arterial blood pressure and heart rate were measured during four phases of the exercise test: at initial rest, during warmup, during the exercise itself, and at rest after the exercise. RESULTS: Systolic and diastolic blood pressures showed no statistical difference between groups. In the comparison between exercise phases, regardless of the group, systolic pressure was significantly higher and diastolic pressure significantly lower at the end of the exercise itself, when compared to all other phases. Resting heart rate was significantly lower in healthy controls vs. G1 and G2, which were not significantly different between themselves. Exercise increased heart rate in all groups. CONCLUSION: This study showed that the groups are normotensive and homogeneous in their results; heart rate was higher in both paraplegic groups compared to healthy controls, but no difference was found between treated vs. untreated groups. Thus, neuromuscular electrical stimulation is a safe and effective way to treat individuals with chronic paraplegia.

“…The blood pressure reflex control is disrupted because of sympathetic hypoactivity and hypotension develops. Other factors in the etiology are changes in baroreceptor sensitivity, loss of pumping functions in skeletal muscles, decondition in the cardiovascular system, hyponatremia and low plasma volume, a fall in plasma catecholmine level, over-response in the peripheral alpha adrenergic receptors, morphological changes in sympathetic neurons, and renin-angiotensin-aldosterone activity [21][22][23][24]. While orthostatic hypotension may be clinically asymptomatic, symptoms such as dizziness, feeling faint, fatigue, clouded vision, and syncope may be seen.…”

ÖzetOmurilik yaralanmaları etkilenen omurilik düzeyine bağlı olarak bireyde fiziksel kısıtlılığa yol açan ve birçok sistemi etkileyen bir sağlık problemidir. Etkilenen omurilik seviyesi ve bunun sonucunda gelişen disfonksiyonun derecesine bağlı olarak erken ve geç dönemde tedavinin yoğun bakım şartların-da sürdürülmesi gerekebilir. Bu hastalarda erken ve uygun tedavi ile sağ kalım artmaktadır. Yine hasta tedavi altındayken oluşabilecek komplikasyonlar açısından dikkatli olunmalı ve hasta konforu açısından bu komplikasyonlarla mücadele edilmelidir. Bizde yoğun bakımımızda servikal fraktürü olan ve kardiyovasküler ve solunumsal problemler ile karşılaştığımız iki vakayı sunmak istedik. Anahtar KelimelerSpinal Kord Yaralanmaları; Pulmoner Komplikasyonlar; Kardiyovasküler Komplikasyonlar AbstractSpinal cord injuries are a health problem that affects many systems and leads to physical restrictions associated with the level at which the spinal cord is affected. It may be necessary to maintain early and late-stage treatment under intensive care conditions according to the degree of dysfunction that develops as a result of the level affected in the spinal cord. With the appropriate early treatment, survival increases in these patients. However, care must be taken with respect to complications that may develop while the patient is undergoing treatment and intervention must be made for these complications to provide patient comfort. In this paper, we present two cases of patients with cervical fractures who developed cardiovascular and respiratory problems while in the intensive care unit.

Cardiovascular autonomic control in paraplegic and quadriplegic

Abstract: The SCIG (above T6) showed greater cardiovascular autonomic impairment compared to SCIG (below T6) and CG. The SCIG (below T6) also presented some degree of autonomic dysfunction. All parameters, linear or nonlinear, are suitable to demonstrate the differences between the SCIG and CG.
