“…Так, в групі з використанням блокади, ЧСС на етапі підтримання анестезії становила в середньому 60 уд/хв, на відміну від групи загальної анестезії, де ці показники рідко знижувалися до 70 уд/хв. ЧСС є важливим показником під час анестезії як для оцінки ноцицептивної відповіді організму на хірургічну травму [9] так і показником важкості крововтрати [10] чи глибини стресової реакції на операцію [11]. Важливо забезпечити не тільки інтраопераційну нормосистолію, але й утримувати ЧСС на рівні 50 -60 уд/хв, оскільки серцевий м'яз кровопостачається в діастолу.…”

Background. Spine surgery is a complex and traumatic surgical intervention that require sufficient anaesthesia supplementation. Erector spine plane block (ESPB) is an effective method of reducing pain intensity, but there is insufficient data on its effect on hemodynamic parameters, blood loss and possible complications. Aim. Compare the impact of ESPB as a component of combined anaesthesia with general anaesthesia without regional component on amount of opiates, blood loss and infusion therapy intraoperatively, intensity of pain postoperatively, to study the consequence of the two methods of anaesthesia on hemodynamic parameters, the time of weaning from artificial ventilation and the duration of hospitalization. Materials and methods. 151 patients underwent spine surgery. Depending on the method of analgesia, patients were divided into two groups: group 1 – general anaesthesia with ESPB, group 2 – general anaesthesia alone. Primary outcomes: intensity of pain at rest and during movements after surgery 6, 12, 24, 36, 48 hours after surgery, duration of hospitalization, time of weaning from the ventilator. Secondary outcomes: amount of fentanyl used intraoperatively and morphine postoperatively, mean arterial pressure (MAP), heart rate (HR), blood loss, diuresis, and infusion therapy during surgery. Results. The intensity of pain at rest and during movement after surgery was significantly lower in group 1. The duration of hospitalization and ventilation was longer in group 2. The amount of opiates intra- and postoperatively was lower in group 1. HR, MBP, blood loss and infusion therapy were higher in group 2. Diuresis did not differ in both groups. Conclusion. ESPB as a component of combined anaesthesia reduces the intensity of pain at all stages of observation after surgery, decrease amount of opiates, duration of artificial ventilation and hospitalization. ESPB diminish HR and SBP, minimize blood loss and infusion therapy without affecting diuresis.

“…Long-term exposure to weightlessness is also known to cause hypovolemia [ 190 , 191 ]. The dominant compensatory mechanism in hypovolemia is a reduction in carotid sinus baroreceptor inhibition [ 192 ] and changes in the sympathovagal balance [ 193 ]. Hypovolemia can be detected by its effect on the respiratory variability of the cardiac stroke volume [ 194 ] and on HRV, which, as described in Section 3.3 and Section 5.2 , can both be computed by BCG and SCG.…”

Ballistocardiography (BCG) and seismocardiography (SCG) are non-invasive techniques used to record the micromovements induced by cardiovascular activity at the body’s center of mass and on the chest, respectively. Since their inception, their potential for evaluating cardiovascular health has been studied. However, both BCG and SCG are impacted by respiration, leading to a periodic modulation of these signals. As a result, data processing algorithms have been developed to exclude the respiratory signals, or recording protocols have been designed to limit the respiratory bias. Reviewing the present status of the literature reveals an increasing interest in applying these techniques to extract respiratory information, as well as cardiac information. The possibility of simultaneous monitoring of respiratory and cardiovascular signals via BCG or SCG enables the monitoring of vital signs during activities that require considerable mental concentration, in extreme environments, or during sleep, where data acquisition must occur without introducing recording bias due to irritating monitoring equipment. This work aims to provide a theoretical and practical overview of cardiopulmonary interaction based on BCG and SCG signals. It covers the recent improvements in extracting respiratory signals, computing markers of the cardiorespiratory interaction with practical applications, and investigating sleep breathing disorders, as well as a comparison of different sensors used for these applications. According to the results of this review, recent studies have mainly concentrated on a few domains, especially sleep studies and heart rate variability computation. Even in those instances, the study population is not always large or diversified. Furthermore, BCG and SCG are prone to movement artifacts and are relatively subject dependent. However, the growing tendency toward artificial intelligence may help achieve a more accurate and efficient diagnosis. These encouraging results bring hope that, in the near future, such compact, lightweight BCG and SCG devices will offer a good proxy for the gold standard methods for assessing cardiorespiratory function, with the added benefit of being able to perform measurements in real-world situations, outside of the clinic, and thus decrease costs and time.
