LOCAL ANESTHESIA IN OPHTHALMIC SURGERY

Electrical skin resistance on Accumulation points in twelve meridians was measured during operation of cataract under local anesthesia. Electrical skin resistance increased an average of 15 percent in bladder, kidney, liver, stomach, gall bladder meridians, and decreased an average 18 percent in lung, small intestine, heart, spleen-pancreas, heart constrictor, triple heater, large intestine meridians. When comparing the skin resistance values with those under acupuncture anesthesia during ophthalmic surgery, the skin resistance value under acupuncture anesthesia exhibited a marked decrease in all meridians (average 23 percent decrease) except the kidney meridian. On the other hand, the skin resistance under local anesthesia was only a 7.4 percent decrease in all meridians except the kidney meridian. It was speculated as one of the reasons for less changes of skin resistance under local anesthesia that sympathetic nervous activity did not occur so much because of pain relief due to local anesthesia.

BACKGROUND: To date, surgical interventions continue to be accompanied by a high proportion of complications and even death. In half of the cases, mortality and serious postoperative complications could have been prevented. After a comprehensive study of the factors affecting the prolongation of hospitalization and rehabilitation (Kehlet H., 1997; Kehlet H., Wilmore D., 2002), surgical stress response was identified as the most significant inducer of dysfunction among various organs and systems. General anesthesia, in its classical sense, is not able to provide patients with complete protection against surgical trauma. Comprehensive protection can be obtained through a combination of general and local anesthesia and stress-protective drugs. OBJECTIVE: The aim of this study was to evaluate the efficacy and safety of the proposed scheme of stress-limiting anesthesia in ophthalmic surgery patients with corneal transplantation. MATERIALS AND METHODS: This study provides a comparative characterization of the severity of the stress response and pain syndrome in patients operated under the conditions of classical general anesthesia (group K) and those who received the scheme of stress-limiting anesthesia (group DB). Multicomponent anesthesia was administered in both groups. Sibazone was used for sedation in group K, whereas dexmedetomidine was used in group DB. The patients in group DB underwent local anesthesia before surgery. The main criteria for assessing the results were as follows: hemodynamic stability, blood glucose, level of venous blood leukocytes, and severity of pain according to the VAS in the postoperative period. RESULTS: Both schemes helped avoid pronounced fluctuations in hemodynamic and gas exchange parameters at all stages of the study. The analysis of blood glucose and leukocyte counts showed that patients in group K had a more significant deviation for both indicators from the preoperative level than those in group DB. In the study of pain syndrome, group K showed higher levels of pain according to the VAS than group DB. CONCLUSION: The scheme of stress-limiting anesthesia enables the control of postoperative pain without the additional use of narcotic analgesics and blockades in the postoperative period.

In ophthalmic surgery, the choice of the method of anesthesia presents certain difficulties for both the anesthesiologist and the ophthalmologist. According to world statistics, the most frequently performed ophthalmic operations are performed in patients of the older age group who have concomitant chronic somatic diseases (diabetes mellitus, hypertension, atherosclerosis, etc.). It is advisable to use local anesthesia in the elderly, as well as in patients with severe co-morbidities or contraindications to general anesthesia. The review presents the characteristics of local anesthetics and the types of local anesthesia used in ophthalmic surgery (vesicular blockade, facial nerve blockade, retrobulbar anesthesia, peribulbar anesthesia, instillation or topical anesthesia). Also in the article, possible complications of these methods of regional anesthesia, their prevention and the principles of emergency care in case of their occurrence are described. Particular attention in the review is given to the toxicity of local anesthetics.
