[Word recognition test after general anesthesia: the influence of previous anesthesia]. / Test prepoznavanja rijeci nakon opce anestezije: utjecaj prijasnje anestezije.

Among other higher brain functions such as consciousness and learning, general anesthesia also affects memory. A number of information retrieval tests are performed to determine the effects of drugs on explicit memory. In this study, we investigated the recognition of words before and after general anesthesia in subjects having and not having received anesthesia on one or more occasions before the present one. The study included 51 patients, ASA physical status I or II, median age 50, at least high-school graduates, without head trauma, known psychiatric or memory disorder, and taking no psychoactive medication. A standardized anesthesia technique, a single surgical procedure and a defined study-test interval were used. We designed our own test as a combination of story recall test and brief word learning test, both widely used in psychological and psychiatric examination. There was no significant difference in word recognition before and after general anesthesia in either patient group. Many studies indicate that anesthesia and surgery are associated with cognitive impairment lasting for 33 months in 10%-14% of elderly patients. We hypothesized that general anesthetics can cause prolonged cognitive alterations. Study results showed that previous anesthesia in addition to the current one had no significant influence on the word recognition test.

[Trauma of the brachial plexus and associated vascular injury--a case report]. / Traumatska ozljeda brahijalnog pleksusa s ozljedom krvnih zila--prikaz bolesnika.

Acute vascular trauma in the axillary region is usually associated with brachial plexus injury and presents a great challenge to surgeon and formidable obstacle to restore a useful limb function. Interdisciplinary operative and postoperative approach is mandatory providing an optimal care of these severe patients. Here we present a case of neurovascular trauma that affected axillary artery and vein, complete transection associated with complete transection of the brachial plexus. Immediately after admission emergency surgery was performed and in postoperative follow up, after several operations and rehabilitation that continued for 24 months, entire functional recovery was achieved without any disabling consequences.
