The method relates to the field of medicine, namely surgery, can find application in the diagnosis of postoperative wound complications in patients with postoperative hernias. The method can be used in everyday practice abdominal surgery to assess the degree of tension of regulatory systems, prediction of postoperative complications.

There are indirect assessment of the risk of postoperative wound complications: comorbidity, the ratio of re-operations and on the analysis of background conditions (Powergen AV Failures grignetti with plastic polypropylene mesh / AV, Powergen, V.L. Halzov // Herniology. - 2007. No. 2. - S-24.; S.A. Langer Prognosis factors in incisional hernia surgery: 25 years of experience. / C.A. Langer, A. Schaper. T. Liersh [et al.] // Hernia. - 2005. - No. 9 - P.16-21).

Selection of methods of prevention as a rule is carried out empirically, on the basis of averaged data on the quantity and quality complications in some diseases (Timoshin A.D. the Results of surgical treatment of postoperative ventral hernias / A.D. Timoshin, A.L. Shestakov, E.A. Galata // Herniology. - 2007. No. 2. - Pp.33-36).

Approximately also formed recommendations on methods of antibiotic prophylaxis and antimicrobial therapy of complications, without a thorough individual assessment of the health status of the patient and evaluation of adaptation the x capabilities of the regulatory systems of the body (Abdominal surgical infection: clinic, diagnosis, antimicrobial therapy: a Practical guide / edited by V.S. Savelyeva, BYR Gelfand. - M.: Littera, 2006. - 168 C.).

There is a need for reliable mathematically calibrated scale is able to predict the risk of postoperative complications on the basis of preoperative health status of the patient and identifying subclinical flowing pathological processes. Method to assess the adaptive capacity of the organism, there is a long, cardiointervalography was developed in the 60-ies of the last century by a group of Soviet scientists working on space medicine under the supervision of Professor R.M. Baevsky (R.M. Baevsky Problem assessment and prediction of functional organism and its development in space medicine / R.M. Baevsky // Advances in physiological Sciences. - 2006. - V.37. No. 3. - P.42-57).

For half a century of existence, the method has gained worldwide recognition and has been successfully applied in various fields of medicine, it is based on the analysis of HRV. (Wayne A.M. Vegetative disorders. / A. M. Wayne): MIA - 2003. - 400 C.).

The proposed method is developed with the use of a known method of learning rate variability (HRV) (V.M. Mikhailov. "Heart rate variability: the experience of practical application of the method", 2002, p.4. http://www.neurosoft.ru/rus/product/book/hrv-2/chapter4.aspx).

Meth is on HRV is the registration parameters sinus cardiac rhythm of the patient, in particular, before and after the performance of various functional tests, such as orthostatic, test with deep controlled breathing, isometric load test, sample the exercise (Bicycle ergometry) and other Sinus node of the heart, as a special unit of the regulation of physiological processes with the universal form of constant response in normal operation makes sure that the particular situation of the values of the heart rhythm. The concept of "the value of rhythm" includes not only the heart rate, the duration of the intervals R-R, but their sequence (R.M. Baevsky Problem assessment and prediction of functional organism and its development in space medicine / R.M. Baevsky // Advances in physiological Sciences. - 2006. - V.37. No. 3. - P.42-57).

Heart rate is an indicator of deviations arising in the regulatory systems of the body, so the study of HRV has important diagnostic value. Since there is practically no such functional States or diseases that would not participated mechanisms of autonomic regulation, the scope of application of the method of HRV analysis is very high. This is due to the fact that the method is relatively simple, relatively cheap, affordable, non-invasive method for assessment of autonomic regulation.

Method HRV is used in the diagnosis when blood hyperten the AI, ischemic heart disease, diabetic autonomic neuropathy (Analysis of heart rate variability using different electrocardiographic systems / R.M. Baevsky, Ivanov I.I., Characin L.V., Havrilesky A.P., dovgalevskii PA, Kukushkin Y.A., Mironov TF, Prilutsky D.A., Semenov A.V., Fedorov V.F., Fleishman A.N., Medvedev M. //Bulletin of Arrhythmology, No. 24, 02.03.2002, p.65; V.M. Mikhailov "heart rate Variability: the experience of practical application of the method", 2002).

But still this method is not practically found its application in surgery (Piksin I.N. Neural network prediction of early postoperative complications in abdominal surgery. / I.N. Piksin, A.A. Solomakha. Bulletin of the Mordovian state University. N.P. Ogarev. - 1997. No. 2-3. - S.112-115.).

The purpose of the proposed method is preoperative diagnosis of occurrence of postoperative complications in patients after protesilaus hernioplasty about incisional hernias by measuring the activity of regulatory systems vegetation.

The objective is achieved by recording the cardiointervalography in the supine position (background sample) and in standing position (orthostatic test) for 300 sec, estimated the rate of activity of regulatory systems (PARS) in points from 1 to 10, increase the top is the number corresponds to the deterioration of the adaptive capabilities of the organism, and when you get the value of PASR 3-10 points predict getting wound complications in the postoperative period.

If indicated PARS corresponding to greater than or equal to 3-10 points apply individualised tactics of patients (the choice of antibiotic prophylaxis leukocyte implant, the choice of alloplasty, drainage of the abdominal wall).

The day before the operation record electrical potentials of the heart rate at rest (lying on the back for 300 seconds), and in translation in a vertical position (orthostatic test standing within 300). Next, a hardware way to analyze the duration of RR-intervals from a prior electrocardiogram both samples. Then create serial number of one hundred and digital Kodo is, the corresponding values of the measured durations of RR-intervals, and subjected to his mathematical analysis, including statistical, pictographically, correlation and spectral processing. Based on the results of the mathematical analysis form codes in the points corresponding to five indicators: the total effect of regulation, functions, automatic, autonomic homeostasis, stability, regulation and activity of subcortical nerve centers. For General characteristics of the activity index of regulatory systems (PARS), combining the scores of these indicators form a code corresponding to the integral indicator of the activity of regulatory systems, the value of which is determined in conventional points from 1 to 10.

PARS allows to differentiate various degrees of tension of regulatory systems and to assess the adaptive capacity of the organism (R.M. Baevsky, 1979, 1984).

Criteria taken into account when calculating PARS:

A. the Cumulative effect of regulation on indices of heart rate (PE).

B. the Total activity of regulatory mechanisms at the average quadratic deviation - SD (or total power of the spectrum - TR).

C. Autonomic balance using a range of indicators: In, RMSSD, HF, IC.

Was the activity of the vasomotor center regulates vascular tone, the power spectrum of the slow waves 1 to adca (LF).

D. the Activity of the cardio-vascular subcortical nervous centre or newsegments levels of regulation of the power spectrum of the slow waves of the 2nd order (VLF).

Values PARS are expressed in points from 1 to 10. Based on the analysis of values PARS can be diagnosed following functional state:

Norm (PARS=1-2)Sostoyanie optimal (working) tension of regulatory systems necessary to maintain an active balance of the organism with the environment.

The state of tension of regulatory systems (PARS=3-4), when for adaptation to environmental conditions, the body requires additional functional reserves. Such conditions arise in the process of adaptation to work, emotional stress or exposure to adverse environmental factors.

State overvoltage (PARS=5-6). regulatory systems, which is associated with the active mobilization of protective mechanisms, including increased activity of the sympathetic-adrenal system and the pituitary-adrenal axis.

State depletion (PARS=7-8) or overvoltage regulatory systems, for which characterize failure 'protective-adaptive mechanisms, their inability to provide adequate reaction of the organism to the influence of environmental factors. Here excessive activation of regulatory item already not supported by functional reserves, there are characteristic signs of pathology. Specific changes clearly prevail over non-specific.

Adaptation failure (PARS=9-10). or the state of Paloma" adaptive mechanisms, when dominated by specificheskie pathological deviations and the ability of adaptive mechanisms for self-regulation partially or completely broken.

Prospective surveyed 200 patients, aged 35-55 years (87 men, 113 women), without severe concomitant pathology and diseases of the nervous system received in the surgical Department routinely operated on for median postoperative hernias MW3-4R0-2 SWR classification (Chevrel I.P., Rath A.M. Classification ofincisional hernias of the abdominal-wall // Ibid. 2000. - Vol.4. Nol. - P.1-7) method of implantation of polypropylene mesh prosthesis.

Using a computer apparatus for the study of heart rate variability ("Neurosoft", Russia) to conduct all transactions account in the supine position (background sample) and standing (orthostatic test) within 300 C. Analysis was performed using the standard program "Polyspectra" (LLC "Neurosoft", Russia). Hardware method was evaluated indicators of activity of regulatory systems (PARS) method R.M. Baevsky. The results of this indicator were grouped (table 1).

<> The state standards or satisfactory adaptation was observed in 49 patients, which is 24.5%) of all examined patients. Complications were observed in 2 patients - gray subcutaneous tissue, which is only 4.1%. When the functional state of tension, which met in 31.5% of cases (63 patients), complications were detected in 7.9% of patients. The overvoltage condition or state is unsatisfactory adaptation (5-6 points) in 46 patients (23% of cases) found 21,7% wound complications in this group. The state of depletion of regulatory systems (7-8 points) in 25 patients (12,5%) led to the identification in this group, 48% of complications. In 17 patients (8.5 percent) from the breakdown of adaptation (9-10 points) wound complications got in 76.5% of the group. The marked increase in the total number of complications is directly proportional to the deterioration PARS.

The largest number of patients (112 patients 56%) before surgery were in the normal or subnormal (voltage) condition adaptive capabilities of the organism. For this category of patients accounted for only 3.5% of cases of wound complications.

The remaining 96.5% of cases, complications occurred in the patients with established dysfunction of varying severity - stress, exhaustion, adaptation failure.

Revealed a clear increase in the total number of complications is directly proportional to the deterioration of hell the operating capabilities of the regulatory systems of the organism of the patient according to PARS. According to a number of complications in a particular group, the difference between the group with normal values PARS (4.1%) and the breakdown of adaptation (76,5%) is to 72.4%.

When apparent homogeneity and integrity of the health status of patients based on the standard scheme pre-operative examination (General blood and urine tests, standard General clinical research), using kardiointervalografii can not be detected clinically differentiable different state of the adaptive abilities of the patient, giving a clear correlation with the frequency of potential wound complications in the postoperative period. The resulting study the adaptive capacities of the regulatory systems of the organism data allow to predict the occurrence of postoperative complications and accordingly to determine individualized tactics of the patient to choose the tactics of preoperative preparation, tactics operations (antibiotic prophylaxis, the choice of plastic, drainage etc) and treatment in the early postoperative period.

Thus, on the basis of obtained data we can conclude about the influence of pre-operative condition of the autonomic nervous system of the patient at risk of developing postoperative complications. The study data PARS before surgery allows siragetdinova the incidence is complicated by the rd after the operation.

Medico-physiological interpretation of HRV indices

Assessment ramagrama and type of regulation sinus rhythm

Rhythmogram of HRV corresponds to the 3rd class. This option ramagrama and structure of heart rate variability indicate pathological stabilization modulation of heart rhythm with the transition of its regulation with reflex, autonomic management level at lower - humoral - metabolic, who are not able to quickly provide homeostasis.

Evaluation of the spectrogram and indicators spectral analysis

Total spectral power neurohumoral modulation drastically reduced.

The state of neurohumoral regulation is characterized by a low level of vagal, sympathetic and humoral-metabolic (cerebr is selected ergotropic) effects in the modulation of heart rate. The balance of the nervous system characterized by the predominance of the activity of the sympathetic division of the autonomic nervous system. Cardiorespiratory synchronization is maintained. The current functional state drastically reduced (-10). Adaptation reserves of regulatory systems 9 points.

Conclusion: the likelihood of wound complications 75%. It is necessary to conduct antibiotic prophylaxis, preoperative preparation. Intraoperatively, you must use a deep ways protesilaus hernioplasty ("sublay" or "underlay"). Without drainage maintenance operative wound. Dynamic observation of the wound after the operation.

Way functional preoperative diagnosis postoperative complications in patients after protesilaus hernioplasty about incisional hernias, including registration cardiotocogram and the measurement of heart rate variability, characterized in that the recording kardiointervalogrammy in the supine position - background sample - and standing - orthostatic test - for 300 s, estimated the rate of activity of regulatory systems (PARS) in points from 1 to 10, increase this number corresponds to the deterioration of adaptive capacity and receiving values PARS 3-10 points predict receipt of wound complications in the postoperative period.

Parameters of cardiorhythmogram (CRG) are registered in lying position: at rest - heart rate, SDNN index; tension index (TI); total spectrum power - Total; value of power in range VLF; value of power in range LF; value of power in range HF. After that in standing position reactivity of sympathetic nervous system is determined by Lf/HF index. In five minutes in lying position recovery of initial heart rate, total spectrum power - Total, increase or reduction of initial power in range of waves: VLF, LF, HF are determined. On the basis of CRG indices, it is estimated which type of cardiac rhythm regulation level prevails: reflex or humoral-metabolic; vegetative balance of sympathetic and parasympathetic impact on cardiac rhythm; reactivity of sympathetic nervous system to functional load: adequate or inadequate. Favourable adaptation is predicted if reflex type of cardiac rhythm regulation prevails over humoral-metabolic, at rest balance of sympathetic and parasympathetic impact on cardiac rhythm is determined, under functional load adequate reactivity of sympathetic nervous system is observed. Unfavourable prediction of adaptation is made if reflex type of cardiac rhythm regulation prevails, but at rest sympathetic or parasympathetic impact on cardiac rhythm is observed, under functional load adequate or increased reactivity of sympathetic nervous system is observed. Unfavourable prediction is made if humoral-metabolic type of level of cardiac rhythm regulation prevails, at rest sympathetic impact on cardiac rhythm prevails and under functional load - inadequate: increased or reduced reactivity of sympathetic nervous system is observed.

EFFECT: method makes it possible to increase reliability of prediction of children's adaptation school.

SUBSTANCE: invention refers to medicine, pulmonology and perinatology. A pregnant woman suffering bronchial asthma of slight severity, in an attack-free period is examined for the functional state of the vegetative nervous system by cardiorhythmography. Detecting a prevailing effect of the sympathetic nervous system by regional lung rheography technique is used to determine a degree of involvement (%) of a medium region of a left lung in air fill (DOmrll%) and a pulse wave propagation time between the heart and the medium region of the left lung (gamrll). It is followed by a discriminant equation: D=-0.054×DOmrll%-11.781×gamrll. If the value D is equal to or more than -2.55, a baby in a in satisfactory condition is expected to be born, while D being less than -2.55, a baby in asphyxia is predicted.

EFFECT: method provides higher prediction reliability.

SUBSTANCE: method involves estimating vegetative tonus using cardiointervalography approach and its medication adjustment under cardiointervalography control. The cardiointervalography examination is carried out before applying treatment, in the course of and after the treatment. Each time vegetative tonus increment is estimated on the basis of voltage index. When applying medication adjustment, nootrop group preparations are used that are selected before applying treatment with initial vegetative tonus disorder distinguished by vagotonia or sympathicotonia being taken into account. Preparation or combination of preparations or their doses and application duration is adjusted on basis of vegetative status direction changes obtained from cardiointervalography examination data. The treatment is continued until vegetative status direction change stops towards normotonia.

EFFECT: enhanced effectiveness in selecting individual treatment course.

SUBSTANCE: the method deals with monitoring the difference in signals obtained from N pickup units, where N ≥ 2, ECG, pulse, temperature and analysis of the range and variability of their rhythms, nonlinear chaotic fluctuations during the period of registration. During analysis one should detect the values for fractal dimensions of Hirst's index and informational Fischer's index standardized, correspondingly, by the average value during either nocturnal or diurnal period. One should conclude upon improved body state by the normalization of signals' difference of peridiurnal rhythm, increased fractal dimensions, Hirst's index, decreased standardized informational Fischer's index, and one should conclude upon worse physiological or pathophysiological processes according to the opposite alterations. The method enables to widen functional possibilities during diagnostics.

SUBSTANCE: the present innovation deals with measuring parameters of electrocardiosignal (ECS) ST-segment and their analysis to detect deviations against the norm. At every step of quantization one should form the readings of first-order differences and modules of first-order differences. One should memorize N of readings for the modules of first-order differences coming after ECS readings that correspond to the onset of cardiocycle. Then it is necessary to sum up memorized values of modules and at every step of quantization one should compare the obtained current sum value with previous one. It is necessary to memorize the greater of them and according to maximal value one should form threshold level to compare current value of modules sum. Time moments when sum value is at first greater and then lower against threshold level one should consider to be, correspondingly the onset and the end of ST-segment. Time segment between the onset and the end of ST-segment should be considered as duration of ECS ST-signal. Device to isolate ECS ST-signal on-line contains a block for forming ECS, a block for primary ECS processing, a quantization block, a block for isolating the point of cardiocycle onset and measurement of its duration, a block to form first-order differences, a block to form modules of first-order differences, a block to memorize readings for the modules of first-order differences, a block to detect the number of summarized readings for the modules of first-order differences, a summarizing block, a block to form a threshold level, a block for comparison and a key device. The innovation enables to isolate ST-segment more reliably for wider class of electrocardiograms at different modifications of QRS-complex form.
