Integrative Monitoring

Objective. To elaborate the intensive therapy tactic in patients, suffering ischemic cerebral insult (ICI) depending on changes in the systemic hemodynamics indices and the oxygen-transportation status.Маterials and methods. In 42 patients, suffering the ICI of middle severity, ageing 45 - 88 years old, the integrative monitoring of the neurological state severity, systemic hemodynamics indices and the oxygen-transportation status on background of targeted intensive therapy was conducted. Results. In the patients, suffering initial hypoxemia, a hypokinetic heart index (HI) - (2,0±0,1) l×min-1×m-2 and the lowered systemic delivery of oxygen (DO2) - (356±21) ml×min-1×m-2were revealed. Prophylactic oxygenation is needed if the value of the oxygen content in arterial blood (SаO2) exceeds 95% and DO2 is lesser than 520 ml×min-1×m-2. Aiming the achievement of eukinetic values of the HI, correction of vascular spasm and antihypertensive therapy was conducted, using alpha-adrenoblocking agent (urapydil) up to stabilization of the DO2 indices on the level of 520-600 ml×min-1×m-2. In hyperoxidal state a hyperkinetic HI - (3.6±0.1) l×min-1×m-2 and a raised DO2 - (699±14) ml×min-1×m-2 were revealed. Prophylactic oxygenation is not indicated if the value of the SаO2 index exceeds 95% and DO2 exceeds 600 ml×min-1×m-2. Aiming to achieve eukinetic values of HI it is mandatory to conduct antihypertensive therapy, using therapy with аlpha-beta-аdrenoblocking agent (labetalol). Conclusion. Targeted intensive therapy, oriented towards balance with general oxygenation of the organism tissues, normalizes the oxygen-transport homeostasis in shortest terms, what impacts the results of treatment in patients, suffering ICI, immediately.

Objective. To determine the tactics of infusion therapy in patients with ischemic stroke (IS) depending on the severity of the violation of energy-structural status (ESST). Materials and methods. A study of 32 patients with severe IS on the National Institutes of Health Stroke Scale (16,7±1,5), who were in the department of anesthesiology with intensive therapy units of the Municipal Non-Profit Enterprise «City Hospital № 9» Zaporizhzhia City Council. Of these, 11 were men (34,4 %; the average age – 68,2±2,5 years), 21 were women (65,6 %; average age – 72,1±1,6). Results and discussion. In patients with IS, disorders ESST were defined as hyperergic damage at values of cardiac index (CI) of 4,45-5,09 L×min-1×m-2 and oxygen consumption index (IVO2) 186-210 ml×min-1×m-2, and at values of CI ≥5,10 L×min-1×m-2 and IVO2 ≥211 ml×min-1×m-2 – as hyperergic insufficiency. While hypoergic damage ESST occurred at values of CI 2,33-1,82 L×min-1×m-2 and IVO2 104-85 ml×min-1×m-2, and at CI ≤1,81 L×min-1×m-2 and IVO2 ≤84 ml×min-1×m-2 hypoergic insufficiency of ESST was observed. The daily fluid requirement of a patient with IS was calculated according to the formula 4+2+1: for the first 10 kg of weight – 4 ml×kg-1×h-1; from 11 to 20 kg – 2 ml×kg-1×h-1; from 21 kg – on 1 ml×kg-1×h-1 (Park G.R., Roe P.G., 2005; Netyazhenko V.Z., Halushko O.A., 2012). Infusion therapy in patients with IS and hyperergic damage ESST was performed with 0,9 % sodium chloride solution according to the formula 4+2+1 on the background of the use of esmolol intravenously bolus 250 mg and subsequent administration of 50 mсg×kg-1×min-1, and in hyperergic insufficiency 500 mg of esmolol intravenously bolus and subsequent administration of 100 mсg×kg-1×min-1. While in hypoergic damage ESST on the background of infusion therapy used dopamine or dobutamine 1-5 mсg×kg-1×min-1, and in hypoergic insufficiency, the dose of dopamine or dobutamine was increased to achieve the desired effect. Conclusions. The personification of infusion therapy depending on the severity of the violation of ESST can improve the results of treatment of patients with IS in the most acute period.

Hypercapnic Acute Respiratory Failure

The aim of this study is to assessment of the rapid effects of t-He/O2 in comparison with the effective level of high-flow oxygen therapy (HPO) on the main indicators of oxygen transport, central and pulmonary hemodynamics in patients with chronic obstructive pulmonary disease (COPD) with hypercapnic acute respiratory failure.Methods. A total of 33 (29 male, 4 female) patients were included in a randomized, comparative study with exacerbation of COPD and acute respiratory failure, admitted to the department of anesthesiology and intensive care of D.D.Pletnev City Teaching Hospital, Moscow Healthcare Department, between March and May 2017. Patients were divided into two groups: the 1st group – 18 patients (15 male, 3 female) receiving t-He/O2 (He – 70%, O2 – 30% at a temperature of 70 °C; the 2nd group – 15 patients (14 male, 1 female) receiving high-flow oxygen therapy with FiO2 – 30% through a Venturi mask for the treatment of ODN against the background of basic therapy of the underlying disease, according to the recommendations of GOLD 2016. Assessment of oxygen transport, central and pulmonary hemodynamics was carried out through the definition of indicators: saturation of hemoglobin of arterial blood with oxygen (SaO2), saturation of venous blood hemoglobin with oxygen (SvO2), partial pressure of arterial blood oxygen (РaO2), partial pressure of arterial blood carbon dioxide (РaCO2), partial pressure of mixed venous blood oxygen (РvO2), partial pressure of mixed venous blood carbon dioxide (РvCO2),mean pulmonary artery pressure (MPAP), cardiac output (SV), heart index (CI), pulmonary vascular resistance (RVRI), impact volume index (SVI), pulmonary vascular resistance index (RVRI), left ventricular shock index (LVSW), right ventricular shock index (RVSW), system speed of oxygen delivery (DO2), the coeffiCIent of extraction of oxygen (ExO2), shunt fractions (venous mixing) (Qs / Qt)).Results. Short-term inhalation with a thermal helium-oxygen mixture in patients with COPD with hypercapnic acute respiratory failure is accompanied by an increase in SaO2 94,1 (92,8; 97,5) initially 86,1 (85,9; 88,1), РаО2 (78,1 (74,8; 80,1) initially 55,2 (52,5; 65,3)), decline РаСО2 (57,4 (54,2; 66.4) initially 65,4 (58,1; 67,2)). Thermal helium-oxygen mixture leads to stabilization of hemodynamics, improving the work of the right and left heart: decline MPAP 28,2 (24,3; 32,8) initially 43,3 (40,1; 49,5), RVRI (285,3 (258,4; 362,7) initially 592,1 (498,2; 623,5)), RVSW (16,2 (14,1; 21,4) initially 25,8 (21,8; 32)), HR 91,1 (86,4; 98,7) initially 115 ((105; 118) to increase LVSW (58,2 (49,8; 62,4) initially 35,5 (28,9; 42,1)), SVI 36,2 (31,8; 42,1) initially 31,5 (28,4; 36,2). Elimination of arterial hypoxemia and a positive effect on hemodynamics ensures adequate oxygen transport to tissues, which is expressed in the normalization of DO2 values DO2 (980,4 (858,45; 1208) initially 280,3 (270,34; 387,4)) и ExO2 (27,8 (25,6; 34,5) initially 32,1 (30,7; 39,8) and decline Qs/Qt. (28,7 (18,6; 35,4) initially 42,8 (39,2; 49,1).Conclusion. Short-term therapy of patients with COPD with hypercapnic acute respiratory failure using the t-He/O2 method, in comparison with high-flow oxygen therapy, improves blood oxygenation and hemodynamics. Elimination of arterial hypoxemia and a positive effect on hemodynamics made it possible to ensure adequate oxygen transport to tissues, which was expressed in the normalization of transport values, oxygen delivery, and a decrease in the shunt fraction.

Background Most patients with congestive heart failure (CHF) develop pulmonary venous hypertension, but right ventricular afterload is frequently further elevated by increased pulmonary vascular resistance. To investigate whether inhalation of a vasodilatory phosphodiesterase-3 inhibitor may reverse this potentially detrimental process, the authors studied the effects of inhaled or intravenous milrinone on pulmonary and systemic hemodynamics in a rat model of CHF. Methods In male Sprague-Dawley rats, CHF was induced by supracoronary aortic banding, whereas sham-operated rats served as controls. Milrinone was administered as an intravenous infusion (0.2-1 microg.kg body weight.min) or by inhalation (0.2-5 mg/ml), and effects on pulmonary and systemic hemodynamics and lung water content were measured. Results In CHF rats, intravenous infusion of milrinone reduced both pulmonary and systemic arterial blood pressure. In contrast, inhalation of milrinone predominantly dilated pulmonary blood vessels, resulting in a reduced pulmonary-to-systemic vascular resistance ratio. Repeated milrinone inhalations in 20-min intervals caused a stable reduction of pulmonary artery pressure. No hemodynamic effects were detected when 0.9% NaCl was administered instead of milrinone or when milrinone was inhaled in sham-operated rats. No indications of potentially adverse effects of milrinone inhalation in CHF, such as left ventricular volume overload, were detected. Moreover, lung edema was significantly reduced by repeated milrinone inhalation. Conclusion If these results can be confirmed in humans, inhalation of nebulized milrinone may present a novel, effective, safe, and pulmonary selective strategy for the treatment of pulmonary venous hypertension in CHF.

Objective. To raise the efficacy of treatment of arterial hypertension in patients, suffering ischemic cerebral stroke of the middle grade of severity on background of determination of hemodynamic variant of arterial hypertension. Materials and methods. Prospective nonrandomized investigation concerning 42 patients, suffering ischemic cerebral stroke of middle severity in accordance to the insult severity scale of National Institute of Health (National Institutes of Health Stroke Scale - NIHSS), was conducted. The patients’ middle age have constituted (69.4 ± 1.4) yrs. There were the central hemodynamic indices measured, the arterial hypertension hemodynamic variant determined, the oxygen and hemodynamic status estimated, and in accordance to the results obtained - the differentiated antihypertensive therapy was administered. All the patients were divided into three groups, depending on hemodynamical variant of arterial hypertension: the first group – patients with eukinetic variant, the second group – patients with hypokinetic variant, the third group – patients with hyperkinetic variant. Hemodynamical variant of arterial hypertension was determined in accordance to the referent level of cardiac index. The groups were representative in accordance to age, height, the body mass, the main and concurrent pathology and the cerebral affection degree. Results. In the patients, suffering initial eukinetic hemodynamical variant of arterial hypertension, the cardiac index have fluctuated from 2.88 to 4.67 l × min-1 × m-2, general peripheral vascular resistance have rested in the norm borders, the oxygen saturation level of arterial blood did not demand the oxygen therapy, index of the oxygen delivery have exceeded the appropriate values and fluctuated in borders from 541 to 903 l × min-1 × m-2. In complex of differentiated antihypertensive therapy there was applied a constant intravenous injection of magnesium sulfate in a daily dose 2500 - 5000 mg. For patients with initial hypokinetic hemodynamic variant of arterial hypertension following signs are characteristic: low cardiac index - from 1.65 to 2.08 l × min-1 × m-2, the enhanced general peripheral vascular resistance - 2813 (from 2393 to 3403) dyne × s-1 × cm-5 and the lowered index of the oxygen delivery - from 306 to 412 l × min-1 × m-2. Differentiated antihypertensive therapy was conducted, using urapidyl: intravenous boluses 1.25 – 2.5 mg with further infusion 5 - 40 mg × h-1. For hyperkinetic hemodynamic variant of arterial hypertension the raised cardiac index is characteristic – 3.75 l × min-1 × m-2 (fluctuated in borders from 3.62 to 4.10 l × min-1 × m-2), as well as normal general peripheral vascular resistance - 1189 (from 1055 to 1449) dyne × s-1 × cm-5 and raised index of the oxygen delivery - 762 (from 725 to 828) l × min-1 × m-2. Differentiated antihypertensive therapy was conducted, using labetalol: intravenous infusion with velocity 2 - 8 mg × min-1. Conclusion. In the patients with ischemic cerebral stroke of the middle grade of severity the conduction of differentiated antihypertensive therapy, taking into account hemodynamic type of arterial hypertension and the oxygen-hemodynamic stabilization of the blood circulation system, improved the results of treatment and accelerated the rehabilitation duration.

Aim of the study to improve the results of treatment of children with intracranial hypertension in the acute period of severe mechanical trauma by virtue of the use of the “Protocol of step-by-step therapy” Material and methods. The article is devoted to the problem of intracranial hypertension in children with severe mechanical trauma. An analysis of 148 case histories of children with severe mechanical trauma, including brain trauma hospitalized in an intensive care unit. 27 patients out of 148 were excluded from the inclusion criteria: 6 patients (22.2%) due to the “late” admission (more than 72 hours from the time of injury); 21 patients - (77,8%) due to the persistent condition of atonic coma from the moment of trauma. 121 patients, according to indications, monitored intracranial pressure and intensive therapy of intracranial hypertension. All patients were divided into two groups: one group (the main one - 84 patients), in which the treatment was carried out according to the “Protocol of step-by-step therapy of intracranial hypertension” and approved in the Scientific Research Institute of Emergency Children’s Surgery and Traumatology, characterized by a strict sequence of treatment measures (“steps”), with clear indications for prescribing each subsequent “step” and the time frame for the duration of the “steps” taken; 2 group (control group - 37 patients), in which the treatment was carried out according to existing international guidelines for the management of patients with severe head injury. Conclusion. Comparative evaluation of treatment results showed outcomes of trauma in the main group to be better, including a statistically significantly less mortality rate (p = 0.0002, p < 0.05).
