Comparative Study Clinical Trial Controlled Clinical Trial[Prevention of postoperative pain: pathogenetic bases and clinical aspects].
The trial aimed at development of pathogenetically sound complex of therapeutic measures to prevent postoperative pain or relieve it significantly included 1912 patients after elective surgical interventions on the lower part of the body. It is shown that basic factors in postoperative pain prevention are the following: a) adequate relief of preoperative pain syndrome; b) use of spinal or spinal-epidural anesthesia as the leading anesthesia method; c) preoperative epidural administration of opioid analgetic drugs; d) pre-, intra- and postoperative administrations of drugs affecting N-methyl-D-aspartate-receptors (ketamine, magnesium sulphate) as well as inhibitors of kininogenesis and prostaglandinogenesis. The success lies in a multimodality approach to prevention of postoperative pain syndrome, i.e. maximal eradication of all the factors promoting onset of pain during pre-, intra- and postoperative period with a simultaneous impact on peripheral and central mechanisms of acute pain. Such an approach resulted in a complete prevention of postoperative pain in 46.2% patients while the rest patients had much less intensive pain.

Comparative Study[Functional state of the right and left heart at different stages of anesthesia in patients with ischemic heart disease during myocardial revascularization surgery].
57 ischemic heart disease (IHD) patients entered the study of right and left heart function at different stages of anesthesia and operation to reveal possible reasons of myocardial dysfunction and to propose effective prevention of this dysfunction. All the patients were operated on under multicomponent balanced anesthesia (relanium, fentanyl, arduan, nitric oxide with oxygen 1:1). Left ventricular function was assessed at Doppler echocardiography, right ventricular function--at catheterization of the lung artery with a Swan-Ganz catheter with low time constant. ⋯ Diastolic and systolic right ventricular dysfunctions were observed at all stages and three stages of the operation, respectively. Diastolic and systolic left ventricular dysfunction was observed at four and one stages, respectively. Basic causes of the above systolic and diastolic disorders in the preperfusion period may be tachycardia, arterial hypertension, reduction of the preloading and increased postloading (for the right ventricle) in artificial lung ventilation.

Comparative Study[Results of the treatment of cardiac surgery patients with postoperative acute respiratory distress syndrome by prone-position pulmonary ventilation].
Prone position ventilation (PPV) became an effective method of management of ARDS since 1974. Its positive effects on arterial oxygenation have been amply described, but its impact on the results of treatment and hospital mortality remains a disputable point. We observed 2 groups of patients, 36 pts. each, with ARDS after cardiovascular surgery. ⋯ Clinical outcomes were better in the PPV group than in the controls: a lower frequency of threatening arrhythmia, better results of MOSF treatment, and lower mortality (69 and 33.4%, respectively). Prone position is an effective measure improving arterial oxygenation in patients with ARDS after cardiovascular surgery. The main results of PPV are decrease in complications induced by hypoxia and higher survival rate.

Comparative Study[Clinical experience with low- and minimal-flow isoflurane in extensive resections of the liver and liver transplantation].
A comparative study was performed of general balanced anesthesia on the basis of neuroleptic analgesia (NLA) and inhalation low- and minimal-flow anesthesia with isoflurane in anesthesiological management of extensive operations on the liver. A total of 75 anesthesias were conducted. ⋯ Low-flow isoflurane significantly lowers pharmacological load with opiates, myorelaxants which is essential in patients with hepatic diseases. This leads to more rapid recovery of adequate spontaneous respiration and activation of the patient in low risk of postoperative iatrogenic complications.
