“…This may reflect a deliberate choice from the anaesthetist to achieve hypothermia in some cases, but this information was not recorded. Hypothermia has been shown to decrease oxygen consumption and minimise organ dysfunction in the event of low circulation or circulatory arrest, as what may happen during occlusion of the venous inflow (Brodeur et al, 2017). However, it may also affect the canine coagulation system and promote hypocoagulation, by inhibiting the enzymatic coagulation cascade, sequestration of platelets in the spleen and the liver and decreased platelet aggregation (Clark-Price, 2015;Sessler, 2016;Brodeur et al, 2017).…”

In humans, hypothermia has also directly been associated with an increase of 16% in blood losses for each degree below the normal temperature (Rajagopalan et al, 2008).…”

Little information is available about the management of adrenalectomies in veterinary anaesthesia. The aim of this study was to describe the anaesthetic techniques, the complication rate and outcome of these cases. Data were collected retrospectively from patients' records. Descriptive statistics were performed with Student's t-tests and Chi-square tests where appropriate. Forty-one cases were included. The mean age was 124.7 ± 29.4 months and the median body weight was 23.1 kg (5.3–69 kg). Carcinoma was the most common diagnosis (34.1%). Premedication was most commonly achieved with methadone alone (70.7%) IV. Propofol was the most common induction agent (39%). An infusion of opioids (80.4%) and an epidural injection of morphine (70.7%) were the most common analgesic techniques. Hypotension was the most common complication observed (51.2%). The mortality rate was 14.6%. The lowest recorded oesophageal temperature was statistically associated with the incidence of haemorrhage (P = 0.025). The invasion of the vena cava (P = 0.001) was significantly associated with haemorrhagic complications. The survival rate was better when patients received hydrocortisone intra-operatively (P = 0.026). This study highlights some possible association between the anaesthetic management and the outcome of the procedure.

“…First, verify the models from different sources in the interest group. It is assumed here that the models used are all logistic regression models [51]. In this way, you can abandon the model that is defective in the interest group during aggregation.…”

Based on deep learning technology, this paper proposes a two-stage colorectal image feature mining and fast recognition model to achieve fully automatic medical image pathology discrimination. Drawing on the ideas of multi-factor Meta-regression analysis widely used in the medical field and the model aggregation framework based on Bayesian prior probability theory, a prognostic model of colorectal tumors suitable for various situations and scenarios is constructed. And using a combination of public data sets and real data sets, design two sets of experiments to verify these models from different angles. The algorithm was used to select one, four, and five related features from three sequences to construct three sets of prediction models. The application of the six algorithms failed to obtain a better predictive model (AUC value range 0.439 ~ 0.640). The algorithm (AUC value 0.750±0.137) and the algorithm (AUC value 0.764±0.128) can be used to obtain models with better predictive performance, and the four models are less effective (AUC value<0.7). In the joint model, the algorithm (AUC value 0.742± 0.101) and the algorithm (AUC value 0.718±0.069) can also be used to obtain a model with better prediction performance. Imagebased imaging histology tags can be used as a non-invasive auxiliary tool for preoperative evaluation of histological grading of CRAC, and are expected to be applied in clinical practice to assist in the development of individualized treatment plans.

“…Zum Zeitpunkt der Prämedikation betrug die mittlere Körpertemperatur der Hunde der Gruppe A 38,5° C (37,9-39,1° C), die der Gruppe AM 38,6 (38,0-39,0° C). Zwischen Prämedikation und Narkoseeinleitung wurde bei einigen Hunden ein Temperaturanstieg beobachtet (6 Hunde der Gruppe A, durchschnittlich + 0,4° C, 4 Hunde der Gruppe AM, durchschnittlich + 0,6° C Zur Definition einer Temperaturgrenze für Hypothermie gibt es in der human-und veterinärmedizinischen Literatur diverse Angaben [5][6] [22]. Für die vorliegende Studie wurde eine untere Körpertemperatur von 34° C als Grenze gewählt, die in der Literatur vielfach als milde Hypothermie eingestuft wurde [6].…”

Zusammenfassung Gegenstand und Ziel Untersuchung des perioperativen Temperaturverlaufs bei gleichzeitiger Anwendung von Acepromazin und Metamizol (AM) im Vergleich zur Anwendung von Acepromazin alleine (A). Material und Methoden In dieser prospektiven, quasi-randomisierten, kontrollierten Studie wurden 20 Hunde, bei denen eine standardisierte Tibial Plateau Leveling Osteotomy erfolgte, hinsichtlich der Prämedikation alternierend 2 Gruppen (A und AM) zugeordnet (je n = 10). Der Verlauf der Rektaltemperaturen wurde ab der Prämedikation bis zum Wiedererreichen einer physiologischen Körpertemperatur nach der Narkose überwacht. Ergebnisse Der Abfall der Temperatur während der Narkose war bei beiden Gruppen vergleichbar (p = 0,12). Postoperativ differierten die Temperaturverläufe der beiden Gruppen signifikant (p = 0,0455). Bei 6 Hunden, die Metamizol erhalten hatten, fiel die Temperatur nach Extubation weiter ab, bevor sie wieder auf physiologische Werte anstieg. Schlussfolgerung Unabhängig von der Studiengruppe entwickelten alle Probanden intraoperativ eine Hypothermie. Postoperativ stabilisierte sich die Körpertemperatur in Gruppe A schneller als in Gruppe AM.
