COMPLEX THERAPY OF GENERAL PURULENT INFECTION WITH USE OF HBO.

Practical recommendations in surgery.

For recent ten years the actuality of problem of treating general purulent infection (GP) steadily improves. This is because the reduction of sensitivity of pathiogenic microbes to antibiotics; lessening of the reactivity of sicks and long-termed period of neglecting of antiseptics contrary to improving of application of antibiotics.

As sepsis isn't a disease itself, but one of degrees of GP, and, besides, sepsis and septic state can't be exactly divided from each other, the following gradation of sepsis is proposed.

1) Purulent-resorbtive fever. Vast purulent foci; wave type development of pathology; intermittence of fever for more than 7 days after disclosing of focus. The inlocations are sterile.

2) Septicemia. These are sicks with sharp purulent infection, hard general state, strong fever, positive inlocations of blood; nevertheless metastatic purulent foci are absent.

3) Septicopiemia. All as for septicemia and presence of metastatic purulent foci.

4) Chronic sepsis. Purulent foci are present; but they are not too active.  The inlocations are not sterile. Periodical sharpening of disease with improvement of temperature.

{septicopiemia}----------------->

chronic sepsis {death }

 

The transitions of these graduations of sepsis can be represented as in Table above (B.Kostuchenok et al.,1977).

Sepsis also can be gradated on the length of time of process:

1) immediate (1 - 2 days)

2) sharp (5 - 7 days)

3) pre-sharp (7 - 14 days)

 

Gradation of sepsis only by clinical forms can't be the foundation

for development of concrete form of therapy; besides the display of disease depends on the time, spent from the beginning of disease. We have gradated the period of the disease at three stages. This is certainly an abstract scheme; each concrete case has its own particularity. Nevertheless this gradation has a practical application, for it signs the essence of metabolical and pathophysiological processes, helping in the selection of identification and treating.

Three periods can be signed in phase of sharp sepsis:

1) tensed phase (1 - 3-d days);

2) catabolic phase (4 - 9-th days);

3) anabolic phase (10 - 30-th days).

The main systematic transgressions, attending sepsis.

1) nervo-psychical transgressions as a sequence of toxic encephalopathia and neirotoxicosis display themselves as apathy or excitation; diphoria; coma.

2) cardiovascular violations - tahicardia; arterial hypotension and vascular dystonia; rhythm violations; trophic violations and myocard ishemia, violations of micro circulation.

3) respiratoric transgressions - tachypnea; improvement of VPM; lowering of coefficient of oxygen utilization; hypohemia; respiratoric alkalos; roenthological displays of lung parenchyma violations.

4) violation of functioning of parenchymathous organs: jaundicity of skin; hyperbilirubinemia; hyperasothermia; isohypostenuria; pathalogy of biochemical indexes.

5) Metabolic transgressions: coagulopathies; changes of water-electrolytic balance; disproteinemia; sharp violations of acid-alkaline balance.

For their determination a complex investigation is required.

Clinical display and treating of sepsis in stage of tension.

In case of insufficient local reaction (inflammation) other systems are included to supply the security of body. Development of hypatalamo-hypophysal system causes the tension of all supplying systems. Disproportion between reducing endogen stock and improving loading cause the decay of energetic stock and hard metabolic violations.

Septic shock with sharp hemodynamic violations and toxic phenomena is dominating in clinical display. Flaccidity; apathy; adynamia (something like after injection of morphine) are being developed as well as foci (abscesses or hematomes) or diffusion (meningitis; encephalopathies; encephalitis). Hemodynamic violations mean disbalance between abilities of vascularity and volume of blood being supported by reduction of pressure or its unstability are developed. Independently of the therapy taxicardia reaches 120 - 140 per min. with slight, tender pulse. Reographic index is only 50 - 60% of normal.

Cardiac violations are released through deafness of sound, systolic noise and rhythm transgressions. Electrocardiogram can determine hypoxic violations on myocard, blockades of conductivity, hard metabolic transgressions. Central venous pressure improves. Violations of micro circulation cause the change of color of face and body. Inter vascular coagulopathia deepens cyanosis and petexial bleedings. Circulation's violations together with hypoxemia caused by lung and oxidation-reduction cycle, produces hard metabolic shifts. Tissue respiration is only 40% of normal. Sharp tachypnea (40) and improvement of VPM in 2 - 2,5 times. Hyperthermia (39 - 40 C) and hectic fever; primary and metastasic purulence improve the violations.

Bacteriologic hemolisines, with the destruction the erythrocytes (1,5 - 2,5 million), cause anemia, violate cerebral circulation. Amount of leukocytes is improving; amount of lymphocytes can reduce even to zero. Strong septic diarrhea vomity, intestine paresis and septic glossites appear.

In treating of sepsis its complete and urgent sanation is required. Further treating includes compensation of sharp cardiac insufficiency; diminishing of toxemia and bacteriemia. Application of antibacterial therapy causes limitation of size of focus; reduction of pain.

Antibacterial therapy. The beginning can't be delayed for 3-4 days to receive data of analyses; active antibiotics would be used against staphylococci (oleandimysine; eritromycine; neomycine; monomycine, ceporine); antibacterial antibiotics are also needed. Synthetic ones are more advantageous: they are more resistant against enzymes, less toxic and don't cause avitaminose.

The best identification is a visual microscopic one. The schedule of medicines for treating is represented.

Usually the applied therapy isn't enough to treat sepsis. Combination is desirable:

a) inhibitors of cellar membrane (penicillines, cephalosorines);

b) detergents (polymixines, antifungous medicines);

c) synthesis suppressers (levomecitine, tetracycline, streptomycin,

macrolides: oleandimicine, erythromycine);

d) managing of the nucleic acid synthesis (actinomicine, rubomicine,

lincomicine).

To improve the concentration of antibiotic in purulent foci the intervascular injections are preferable.

The application of antibiotics by no means reject application of antiseptics: local (furaciline, rocal, dioxydine, etc.) and general ones (1% blue metilen, chlorophillipt solution).

 

The sulphanilamines, especially prolonged ones, are also of use. They strengthen the activity of antibiotics and lessen their toxicity; they are of peroral utilization: sulphodemisine -4-6g on four receptions per day; sulphodemitoxine -1g a day; sulphacamphocain -10% solution 2ml, 4-6 times a day, injections. The displays of efficiency of therapy are reductions of inflammations; intoxication; fever; the purulent focus would compulsory become opened.

2. Specifications of catabolic phase of sepsis and their treating.

The peculiarity of that phase is improvement of protein, lard and carbohydrate catabolism, utilization of enzymes, reduction of functional abilities of organs and systems. De compensation of water-electrolyte and acid-alkaline balances as well as inactivation of enzymes take place. The zone of inflammation and destruction enlarges. Secondary infections are usual. Purulent activity improves reduction of proteins. Purulent activity is supported by endogen toxins (appearing as the result of catabolic processes and decay of necrotic tissue). All these determines the specification of therapy: treating of focus first of all by means of local antibioticotherapy and streaming aspiration method. As the control lessening of fever and local inflammations can be taken.

Local application of proteolitic enzymes (tripsin or chymopsin,10-20 mg per 30-50 ml of solution lessens the resistance of microbes and inflammation. But on the other hand it can improve sepsis. A severe control of proteolytic activity of blood is needed. The application of antibioticotherapy would be based on antibioticogram: the mistakes in selection of medicine can cause antibioticoresistance, toxic activity and disbacteriosis; allergic and toxic reactions.

Besides controlling of these complications the sensitivity analysis

to an exact antibiotic is required. Deintoxication therapy besides the resorbtion in wound (drainage, aspiration) deletes toxins from vessels (diariesis; hemodialysis, peritoneal dialysis).

Enforced diariesis begins from 2-3hours of water loading by isotonic solutions of electrolytes and glucose, controlled by hemocritis and OCK with following by injection of mannitol (1g/kg). Water loading goes on with solution of 2,5-4g KCl, 6g NaCl and 10g of glucose per 10l of solution. The speed of injection would be equal to speed of diuresis and can be estimated from:

speed of injection (drop/min.) = volume for injection (ml)/time of treating (hours)

This cycle can be repeated, if required. The contraindications are: collapse after cardiovascular deficiency and transgressions of kidney activity (with azotemia,oliguria). During that procedure the level of electrolytes would be as represented in Table 6.

Correction of hemodynamic violations is done simultaneously with detoxification. Improvement of protein losses cause the requirement of improvement of dose of injecting protein. Anabolics are also desirable here: retabolil injections in tissue (1ml once a week); nerobol (0,05 twice a day). Reception of adjuvants would be interrupted. Injection of antistaphylococci plasma would be held on the 14-th day after the beginning of disease. Anatoxin is injected under skin, 0,5ml. Injection of vaccine done from dead micro flora is permitted - first injection - 0,05ml; later - dose would be doubled each time; 10-12 injections on the whole. Microbial polysaccharides, purines and pyridines.

3. Clinical pathology and treating of sepsis in anabolic stage.

Recreation includes a special period when anabolic processes are dominating and the structural proteins are restored. It usually goes moderately; but sometimes has a sharp character - so called "vagal cryse", lasts for several hours with following healing. During anabolic period endocrine-vegetative mechanisms are developed with stimulation of protein and carbohydrate synthesis (hypertension of parasympatical vegetative system and hyper secretion of anabolics). Steady graduate recreation takes place. Estimates, based on utilization of nitrogen in body, represent the development of 120g of tissue every day. The task is to supply that process with energy and plastic materials. Good diet, proteins, vitamins are required. The antibiotic therapy would be interrupted if the recreation goes on; otherwise the schedule of used antibiotics would be changed according to antibioticogram and therapy would go on.

4. HBO in case of GP.

Difficulties in treating of GP force to develop new methods of doing that. The task is: supplying with conditions of the best recreation of organs and systems of body; activation of reserves and compensatory systems in new conditions of aggression; stimulation of regeneration and reduction of treating period. As far as oxygental shortages are usually developed at the end of sepsis, in Yaroslavl Medical Institute HBO was proposed to be included in recreation therapy.

4.1. Indications for the application of HBO.

a) hard metabolic transgressions, caused by toxic-inflammation process and hyperpirexia;

b) respiratory violations of various degrees;

c) cardiovascular deficiency resulting from septic activity (myocardit; endocardit; pancardit; etc.);

d) hemolysis and violation of blood recreation system by microbes and toxins;

e) sharp violations of parenchimatous organs.

4.2. Patophysiological proposals for application of HBO in treating sepsis.

Excitators of purulent infection acting on blood and cells, can combine high active symptomatic compounds. Hyper production of catecholamines cause hemodynamic violations. Activity of toxins in tissue results in gystamino- and seratino-like complexes which cause vasodilation and stasis, sharpening circulatory violations. Transgressions in micro circulatory cause supply of tissue with oxygen. Ishemiac anoxia together with damaging cardiac muscle cause congestion. Adding coagulopatic violations deepen the violation of oxygental supply.

As the result the syndrome of "shock lung" is formed with sharp respiratory deficiency. Compensatory tachypnea, improvement of VPM, taxicardia cannot compensate the shortage of oxygental supply of arterial blood.

Violations at the first step of oxygental circulation cause the improvement of anaerobe phase of metabolism with improvement of synthesis of organic acids. Acidation of pH embarrasses the termination of oxygen to hemoglobin. Anemia and hemoglobinopatia cause hemic hypoxia.

In these conditions cellar membranes can't protect from external aggression and tissue hypoxia is developed. All kinds of hypoxia in mix combine complex hypoxia.

Described mechanism of development of hypoxia in conditions of GP is the first reason for application of HBO.

Generalized surgeonal infection is caused by microbes; the improved pressure of oxygen directly influences on them with inhibition. This is the second reason for application of HBO in complex treating of sepsis.

GP significantly weakens the protective system; normalization of oxygental balance on contrary improves immune system and its response on aggression. This is the third reason for application of HBO in complex treating of sepsis.

4.3. General recommendations on application of HBO.

Permanent control of state of patient is compulsory during the procedure.

For prophylaxis of otorhinolaryngologic transgressions dropping of 3% solution of ephedrine or 1% solution of adrenaline are used.

All kinds of oil and would be removed from the skin before the procedure.

Maximal aeration of wound is required - it accelerates the necrosis and releasing of wound with later recreation.

The first procedure is additionally important for it permits to discover individual sensitivity to oxygen. Selection of time, working pressure of oxygen, amount of procedures depends on the age, additional diseases, hardness of sepsis transgressions and other individual specifications.

Scheme of application of HBO dependently of hardness of process (table of amount of procedures per day during HBO therapy.

If the maximal pressure of chamber is less than 3AT, the isopression period would be prolonged to preserve the multiplication of tine and pressure of procedure unchanged.

4.4. Specifications and results of application of HBO at different stages of GP.

In tension phase HBO prevents from hypoxic damaging of tissue. The pressure is 3AT; saturation (isopression period) - 60 - 80 min.; break between the procedures - 4-6 hours. As usual already after 3-4 procedures the toxic-infectional displays are lessening; temperature falls; arterial pressure, respiration and pulse are normalized; improves auresis; lessens azotemia; betters acid-alkaline balance. Oxygenation of arterial blood comes also to normalized. Purulent processes, inflation and hypermia around the wound are lessening. >From 6 to 8 procedures would be held in that period.

In catabolic phase HBO improves reparation. One procedure a day is proposed in that period with 2AT pressure and saturation for 40 min. That regime excludes oxygental intoxication with prolongation of influence of HBO.

Indications for finishing of HBO are: recreation of patient; diminishing of violations to be healed; active reparation in wound.

Following the recommendations of application of HBO maximally lessens the risk of complications; nevertheless permanent control of patient is necessary to prevent barotraumata or oxygental intoxication.

4.5. Complications and risk of HBO.

The displays of oxygental intoxication are: paleness; trembling of mouth; sweatiness; dizziness; vomity. Pulse is improving. Interruption of injection of oxygen and extra decompression are required. Repetitive procedures can be tried only with reduced pressure (less 2AT) and saturation time.

 

Conditional contraindications for HBO are:

a) epilepsy;

b) caverns in lung;

c) violations of respiratoric conductivity;

d) claustrophobia;

e) improved sensitivity to oxygen.

 

Complex therapy including HBO of 140 patients with GP pathology in Yaroslavl Medical Institute permitted to reduce the lethality to 27%.
