[The problem of acute pain in postoperative period].

The problem of postoperative pain remains actual despite the existence of a variety of pharmaceutical and nonpharmaceutical methods of anesthesia. Acute postoperative pain is an essential component of the surgical stress syndrome. Opioid analgetics (Buprenorfin, Nubain, Tramal, Promedol, Morphine) take the leading position among other types of analgetics. Present-day individual approach to administration of analgetics is still imperfect. The use of a standard dose of analgetics appears to be inadequate in a number of patients. The increase of opioids dose may lead to adverse reactions. In view of this it is valid to use nonsteroid antinflammatory medicines (Ketorolac). The choice of a proper dose of an analgetic is critically important in achieving adequate anesthesia. Patient-controlled analgesia (PCA) or "analgesia on demand" is an alternative to administration of analgetics. The major advantage of PCA is the opportunity to achieve the rate of analgesia, according to individual demand of a patient. Besides, PCA allows to reach the desired effect much faster and to maintain the stable plasma level of an analgetic. 2-year experience of the PCA use in more than 200 patients of the National Research Centre for Surgery ICU has been analysed. The authors advocate use of PCA in clinical practice.

[The problem of adequate analgesia in the postoperative period].

Despite numerous methods of drug and non-drug analgesia, acute pain relief remains a pressing problem, particularly for the postoperative period. Individual protocols of analgesia are still to be developed. Standard doses of analgesics, administered in some intensive care wards, may be inadequate in some patients. An increase of an opioid dose may lead to untoward reactions. Therefore, we consider therapy with nonsteroid antiinflammatory drugs (ketorolac) justified. An important trend in improvement of the efficacy of drug analgesia is evaluation of a sufficient analgesic dose. Patient-controlled analgesia (PCA), administered in accordance with the patient's request, is an alternative to the traditional analgesia administered according to indications (planned analgesia). The main advantage of PCS in comparison with traditional administration of analgesics are effective analgesia meeting the individual requirements of a patient, rapid desired effect, a shorter period without analgesia, stable concentration of the analgesic in the plasma, time saving for the staff, and a lower incidence of side effects. PCA has been used in 227 patients in intensive care wards of Research Center of Surgery. The majority of patients appreciate this method high, which results in adequate analgesia in 82-95% cases.

[Use of lornoxicam for analgesia in the early postoperative period].

Lornoxicam was used for analgesia in 64 patients on days 1-2 after extensive interventions. The drug efficiency and safety were evaluated depending on the dose and route of administration. Intravenous infusion of lornoxicam in a daily dose of 24 mg (basic therapy) did not involve the use of opioids in 35% patients and its analgesic effect was higher than that of promedol monotherapy. Combined therapy with lornoxicam and promedol allows reduction of promedol dose by 25-50% and the incidence of untoward effects by 27-44%.

[Study of analgesic efficacy of propacetamol in the postoperative period using a double blind placebo controlled method].

The efficiency and safety of postoperative use of propacetamol was estimated in 30 patients by means of double blind placebo controlled method. The first group consisted of 15 patients to whom propacetamol was introduced intravenously in single dose of 2 g along with patient controlled anesthesia with promedol. Placebo in combination with patient control anesthesia were used in 15 patients from the 2nd group. Intravenous introducing of propacetamol in dose of 2 g in 15 minutes provides relief of pain intensity in postoperative period. So it permits to consider propacetamol as basic non-opioid analgesic. In early postoperative period combination of propacetamol and opioid analgesic (promedol) reduces demands in the latter by 44%.

[Clinical aspects of the use of nubain, tramal and moradol in patients in the early postoperative period].

Opioid analgesics were used in 282 patients on the first-third day after heart, lung and abdominal surgery. The main indication for their use was pain syndrome. Adequate analgesia with tramal, nubain and moradol was noted in 73, 76 and 81% of cases. In marked pain syndrome after thoracotomy the most effective agents were moradol and morphine. Computer monitoring of the respiratory function in tramal analgesia has shown a decrease in lung ventilation, esophageal pressure, inhalation volume, O2 production. Tramal, nubain and moradol in analgesic doses did not inhibit respiration. In adequate analgesia there was a decrease in lung ventilation which was not accompanied by shifts in acid-base balance of the arterial blood. The above analgesics had no considerable effect on systemic hemodynamics, though the use of tramal decreased systemic blood pressure and the use of moradol decreased systemic blood pressure and total peripheral vascular resistance. Tramal was most effective for synchronization of spontaneous respiration with a lung ventilation device in prolonged ventilation, as well as for the arrest of muscular tremor in the postoperative period. Tramal was effective in 95% of patients in the early post-anesthesia and postoperative period.

[Clinical aspects of using patient-controlled analgesia with nonsteroidal anti-inflammatory agents in postoperative period].

We used lornoxicam (n = 16) and ketorolac (n = 20) to study the possibilities of applying the non-steroid anti-inflammatory drugs within the postoperative patient-controllable analgesia (PCA). With respect to a used analgetic, the frequency rate of good PCA anesthetic results was found, on day 1, to be 60-77%. The good anesthetic results were registered in 25% of patients when the routine scheme was in use. Non-steroid anti-inflammatory agents (lornoxicam, ketorolac) can be prescribed within the early postoperative PCA as basic analgetics, which essentially reduces the need in promedol without worsening the analgesia efficiency.

[Immunocorrectors in the complex treatment of postoperative suppurative-inflammatory complications in surgical patients and monitoring of immunological parameters].

The results of monitoring of immune parameters in different categories of surgical patients with postoperative purulent-inflammatory complications are described in the paper. The combined type of secondary immunodeficiency and degree second immunodeficiency according to A.M. Zemskov were detected in all patients. Immunocorrecting drugs, like polyoxidonium, imunofan and likopid, were added to the complex treatment of patients with the above complications. Their administration normalized the dynamic clinical course of the purulent-inflammatory processes and restored the immunological parameters.

[The immune status and its correction in patients after reconstructive surgeries for cicatricial stenosis of trachea].

The immune status was analyzed in 28 patients with cicatricial stenosis of the trachea for the purpose of determining the type and nature of affection as well as for the purpose of evaluating the clinical efficiency of galavit immunomodulator. Combined impairments were diagnosed in the patients. Moderately decreased CD4+, CD8+, CD16+, significantly decreased CD25+, HLA-DR, CD71+ and increased CD4+/CD8+ were detected at the cell level. An essentially lower CD20+, a higher content of IgG and a reduced FAN were observed in the humoral chain. Therefore, galavit, when used preoperative and immediately after surgery in patients with cicatricial stenosis of the trachea, had a positive effect on the immune status; it reliably increased the count of T-helpers (CD4+) and of natural killers (CD16+) and it induced the phagocyte activity of neutrophils.

[Experimental rationale for possible clinical use of biodialysis].

At biodialysis, the bloods of a patient and a donor simultaneously pass through the individual mass exchangers. The cavities of the dialyzing fluid of both mass exchangers hydraulically interconnected with recurculating transport medium. The metabolites accumulating in the patient's blood pass through the membrane to the transport medium and then the second membrane to the donor's blood and they are eliminated via his/her liver and kidney. At the same time, regression occurs: the substances required for normal vital activity move from the donor's body to the patient's one. Experiments on pigs in one of which both kidneys were removed yielded clearances of major toxic metabolites by approximately 2 times less than that at routine dialysis. Daily sessions of biodialysis ensured a satisfactory state and stable levels of metabolites. At biodialysis, the state did not deteriorate. In the other series of experiments, choledochus was ligated in one of the pigs and sessions of biodialysis were initiated following 24 hours. Daily sessions could achieve stabilization of the level of bilirubin within 135 micromol/l. In the donor pig, the level of bilirubin slightly increased. Its condition remained to be satisfactory.

[Clinical use of tramal in patients in the early postoperative period].

Tramal was given to 204 patients who were operated on the lung, heart, abdomen. During pain therapy, good and satisfactory results were on average obtained in 75% patients operated on the lung, in 77%, on the heart, in 89%, on the abdomen, in 70%, on the great vessels. The absence of the inhibitory effect of the drug on the respiratory center and its slightly marked sedative effect allow one to recommend the agent for application in the early period following the surgery when narcotic analgesics still retain their effect and a real risk of their overdosage exists. During prolonged artificial pulmonary ventilation in the early postoperative period and in impaired adaptation of the patients to a respirator, tramal aids normalization of lung mechanics and hemodynamic parameters without eliminating and suppressing the patients' consciousness and results in cessation of muscular shivering. Adverse effects of tramal are of no decisive clinical significance and occur mainly when the drug is rapidly injected into the vein.

[Clinical use of ketorolac (ketrodole) for analgesia in the early postoperative period].

Ketrodole was administered to 30 patients operated on the abdominal organs, heart and major vessels, lungs and bronchi. The drug was used in a single dose of 30 mg, the maximal daily dose being 90 mg for 16 young patients and 60 mg for 14 elderly patients. Adequate analgesia depending on the time of ketrodole use was attained in 74 to 95% of patients. In 60% of patients with medium intensive pain ketrodole may replace potent opioid analgesics or reduce their daily dose two- or threefold. Ketrodole in the doses used is a relatively safe analgesic.
