[PERIOPERATIVE MANAGEMENT OF PATIENTS WITH DIABETES MELLITUS.]

The article is devoted to the existence of the problem of intraoperative provide patients with concomitant diabetes mellitus: a disease is not diagnosed in time, it increases the probability of death in the performance of surgery by 50%, where as the timely prevention and preparation reduces the chance of developing specific complications to the level of patients with the general population. The paper discusses the recommendations developed by the British Association ofEndocrinologists 2011 and Russia in 2015, as well as the Association ofAnaesthetists of Great Britain and Ireland (2015), provides practical recommendations for the preoperative preparation, anesthetic and resuscitation provide patients with concomitant diabetes mellitus.

[INDUCTION OF ANESTHESIA ON THE BASIS OF DESFLURANE AND FENTANYL--DANGER IN THE AMBULATORY SURGERY].

PURPOSE: To study the possibility of desflurane use for induction of anesthesia. MATERIALS AND METHODS: We analysed the intra- and immediate postoperative periods in 125 patients. Depending on the intended anesthesia method patients were randomised (the method of the envelopes) and included in one of two study groups: 1--volatile desflurane-based anesthesia (n = 62); 2--volatile sevoflurane-based anesthesia (n = 63). RESULTS: Desflurane based anesthesia led to apnea until the installation of laryngeal mask in 94.5% of patients (of 54), for whom a completion of inhalation induction was possible, whereas sevoflurane based anesthesia.led to apnea occurred only in one patient (1.6%). CONCLUSIONS: "Step up" desflurane-based inhalational induction and sevoflurane-based maximum concentration inhalational induction "without primaryfilling of the circuit" showed no significant in time necessary for achieving an anesthetic concentration essential for LMA installation. In both groups it was 3-5 min. desflurane-based volatile induction with addition of fentanyl led to apnea in 97% of patients and associates with a higher risk of bronchospasm.

Measurement of the τ-lepton lifetime at Belle.

The lifetime of the τ lepton is measured using the process e+ e- → τ+ τ- , where both τ leptons decay to 3πν(τ). The result for the mean lifetime, based on 711 fb(-1) of data collected with the Belle detector at the ϒ(4S) resonance and 60 MeV below, is τ=(290.17±0.53(stat)±0.33(syst))×10(-15) s. The first measurement of the lifetime difference between τ+ and τ- is performed. The upper limit on the relative lifetime difference between positive and negative τ leptons is |Δτ|/τ<7.0×10(-3) at 90% C.L.

Observation of anomalous upsilon(1S)pi+pi(-) and upsilon(2S)pi+pi(-) production near the upsilon(5S) resonance.

We report the first observation of e;{+}e;{-}-->Upsilon(1S)pi;{+}pi;{-}, Upsilon(2S)pi;{+}pi;{-}, and first evidence for e;{+}e;{-}-->Upsilon(3S)pi;{+}pi;{-}, Upsilon(1S)K+K-, near the peak of the Upsilon(5S) resonance at sqrt[s] approximately 10.87 GeV. The results are based on a data sample of 21.7 fb;{-1} collected with the Belle detector at the KEKB e;{+}e;{-} collider. Attributing the signals to the Upsilon(5S) resonance, the partial widths Gamma(Upsilon(5S)-->Upsilon(1S)pi;{+}pi;{-})=0.59+/-0.04(stat)+/-0.09(syst) MeV and Gamma(Upsilon(5S)-->Upsilon(2S)pi;{+}pi;{-})=0.85+/-0.07(stat)+/-0.16(syst) MeV are obtained from the observed cross sections. These values exceed by more than 2 orders of magnitude the previously measured partial widths for dipion transitions between lower Upsilon resonances.

Measurement of the tau lepton mass and an upper limit on the mass difference between tau+ and tau-.

The mass of the tau lepton has been measured in the decay mode tau-->3pinutau using a pseudomass technique. The result obtained from 414 fb-1 of data collected with the Belle detector is Mtau=[1776.61+/-0.13(stat)+/-0.35(sys)] MeV/c2. The upper limit on the relative mass difference between positive and negative tau leptons is |Mtau+-Mtau-|/Mtau<2.8 x 10-4 at 90% confidence level.
