Some problems of the regional anesthesia are discussed in the first part of the paper: the kind and the length of the needles, the anesthetic substances used, the retrobulbar and parabulbar technique, the complications. In the second part of the paper the effects of the drugs used in general anesthesia on the intraocular pressure and the possibilities of preventing and treating the oculocardiac reflex are show.

Effects of regional anesthesia on perioperative outcome.
To provide an overview of current knowledge, this article reviews experimental and clinical data from investigations examining effects of regional anesthesia on perioperative morbidity in specific physiologic systems. The issues of morbidity and mortality following general and regional anesthesia are addressed, as are the development of perioperative thromboembolism and blood loss, which are known to be increased during general anesthesia. Finally, the effects of regional anesthesia on the vascular system, the perioperative stress response, and the pulmonary function are discussed.

General anesthesia is a state of reversible, descending depression of the central nervous system that is induced by inhalational or intravenous drugs. Components of general anesthesia include hypnosis, analgesia, amnesia, and muscle relaxation. Recognized anesthesia providers include CRNAs and anesthesiologists. Improvements in pharmacologic agents, technology, and education of providers have sharply reduced morbidity and mortality associated with anesthesia.

Review[Mucociliary clearance function and medicamentous modification].
Mucociliary clearance represents a complex self-cleaning mechanism of the lung and is based on the functional unity of ciliated columnar cells and the special viscoelastic properties of the secretion produced in the tracheobronchial system. It has been known for a long time that intubation and mechanical ventilation can impair mucous transport and lead to morphological damage to the tracheobronchial mucosa. Recent studies made it clear, however, that mechanical ventilation during anaesthesia using an appropriate anaesthesiological technique has no deleterious effect on mucus transport in patients with healthy lungs. ⋯ In these patients a number of factors combine to form a formidable potential insult to the mucociliary transport mechanism. Numerous drugs can affect mucociliary transport. Beta-mimetics and theophylline, in particular, have a favourable effect on mucociliary transport, whereas the effect of mucolytic agents is controversial.

To evaluate the perioperative risk to nonparturients with Eisenmenger's physiology for noncardiac surgical procedures. ⋯ A variety of anesthetic techniques and drugs may be used successfully in nonparturients with Eisenmenger's physiology undergoing noncardiac surgery. Although the study group is small, the perioperative mortality risk is lower than that for parturients undergoing either labor and delivery or cesarean section and is probably in the range of approximately 10%.
