Observational Study
Spinal or general anaesthesia for surgical repair of hip fracture and subsequent risk of mortality and morbidity: a database analysis using propensity score-matching.
Around 76,000 people fracture their hip annually in the UK at a considerable personal, social and financial cost. Despite longstanding debate, the optimal mode of anaesthesia (general or spinal) remains unclear. Our aim was to assess whether there is a significant difference in mortality and morbidity between patients undergoing spinal anaesthesia compared with general anaesthesia during hip fracture surgery. ⋯ There was no difference in 30- or 90-day mortality in patients who had spinal rather than general anaesthesia (OR [95%CI] 0.97 [0.8-1.15]; p = 0.764 and 0.93 [0.82-1.05]; p = 0.247 respectively). Patients who had a spinal anaesthetic had a lower-risk of blood transfusion (OR [95%CI] 0.84 [0.75-0.94]; p = 0.003) and urinary tract infection (OR [95%CI] 0.72 [0.61-0.84]; p < 0.001), but were more likely to develop a chest infection (OR [95%CI] 1.23 [1.07-1.42]; p = 0.004), deep vein thrombosis (OR [95%CI] 2.18 [1.07-4.45]; p = 0.032) or pulmonary embolism (OR [95%CI] 2.23 [1.16-4.29]; p = 0.016). The mode of anaesthesia for hip fracture surgery resulted in no significant difference in mortality, but there was a significant difference in several measures of postoperative morbidity.

A 42-year-old female patient suffered an infranuclear hypoglossal nerve paresis with right-sided swelling and weakness of the tongue following a short duration mask anesthesia for a follicle puncture. This resulted in dysarthria and dysphagia persisting for more than 3 months. A return to work was initially impossible. ⋯ Conclusion for clinical practice: In order to protect against lesions of the hypoglossal nerve, the pre-anaesthesiological examination should ask specifically about cervical problems as an indication of individual sensitivity to reclination. In such cases, special attention should be paid to careful patient positioning. Even shorter periods of reclination or compression of the soft tissues of the neck can result in lesions, therefore tolls such as a Wendl or Guedel tube should be used accordingly.

Recent studies point to a fundamental distinction between population-based and individual-based anaesthetic pharmacology. At the population level, anaesthetic potency is defined as the relationship between drug concentration and the likelihood of response to a stimulus. At the individual level, even when the anaesthetic concentration is held constant, fluctuations between the responsive and unresponsive states are observed. Notably, these spontaneous fluctuations exhibit resistance to state transitions Rst. Therefore, the response probability in each individual depends not just upon the drug concentration, but also upon responses to previous stimuli. Here, we hypothesise that Rst is distinct from drug potency and is differentially modulated by different anaesthetics. ⋯ Whilst equipotent doses of distinct anaesthetics produce comparable population response probabilities, they engage dramatically different dynamics in each individual animal. This manifests as a differential aggregate propensity to exhibit state transitions. Thus, resistance to state transitions is a fundamentally distinct, novel measure of individualised anaesthetic pharmacology.

Use of Dexmedetomidine and Opioids as the Primary Anesthetic in Infants and Young Children: A Retrospective Cohort Study.
Anesthetic regimens using dexmedetomidine and short-acting opioids have been suggested as potential alternatives to sevoflurane-based anesthesia in children. The primary aim of this study is to compare demographics, intraoperative characteristics, and complications of general anesthetics in which dexmedetomidine and opioids were used without sevoflurane, or in combination with a low sevoflurane concentration, in children 36 months old and younger. The secondary aim is to evaluate intraoperative bispectral index (BIS) values when available in these patients. ⋯ Dexmedetomidine and opioids can effectively be used in young children as an alternative total intravenous anesthesia technique with or without <1 minimum alveolar concentration of sevoflurane. Bispectral index monitoring reveals a likely sufficient depth of hypnosis.

ReviewEIGHTY YEARS OF ELECTROCONVULSIVE THERAPY IN CROATIA AND IN SESTRE MILOSRDNICE UNIVERSITY HOSPITAL CENTRE.
In 1937, Ugo Cerletti and Lucio Bini performed electroconvulsive treatment (ECT) in Rome for the first time. That was the time when different types of 'shock therapy' were performed; beside ECT, insulin therapies, cardiazol shock therapy, etc. were also performed. ⋯ As early as 1940, just two years after the results of the ECT had been published, it was also introduced in Croatia, at Sestre milosrdnice Hospital, for the first time in our hospital and in the then state of Yugoslavia. Since 1960, again the first in Croatia and the state, we performed ECT in general anesthesia and continued it down to the present, with a single time brake.
