RESUMO
The objectives of this prospective, randomized, blinded, crossover, experimental study were to detect the potential anaesthetic- and analgesic-sparing effects of classical music provided to dogs undergoing skin surgery, and to investigate the role of substance P as an intraoperative pain indicator. Twenty dogs were included, each subjected to three different treatments: Chopin music, Mozart music and no music. They were premedicated with acepromazine, butorphanol and meloxicam and anaesthetized with propofol and isoflurane. Fentanyl was used as rescue analgesia. The anaesthetic depth was monitored by using the bispectral index along with standard anaesthetic monitoring, and autonomic nervous system responses were used to monitor the adequacy of analgesia. Furthermore, measurements of substance P serum concentration were carried out. Dogs exposed to music required less isoflurane and fentanyl. Furthermore, a statistically significant effect of time on substance P concentration was observed regardless of exposure to music, and there was a significant interaction effect between different timepoints and the type of acoustic stimulus. Classical music seems to have an isoflurane and fentanyl sparing effect on dogs undergoing minor surgery. Following surgical stimulation, the serum substance P concentration increases rapidly, and thus appears to be a potentially useful pain indicator.

PURPOSE: To evaluate the effect of post-surgical photobiomodulation therapy in dogs. METHODS: Twenty dogs were selected for elective gastropexy and randomly divided into a control (CG, n = 10) and a PBMT group (PBMTG, n = 10). Premedication consisted of medetomidine and butorphanol. Meloxicam was administered before the procedure. Induction was performed with propofol and maintained with sevoflurane. Local blocks with lidocaine were used. Incisional gastropexy was performed in all animals. PBMTG received PBMT immediately after surgery. The need for postoperative rescue analgesia, if the animal had eaten by the evaluation momen, and pain scores were collected using the Glasgow Composite Measure Pain Scale - Short Form (CMPSSF) at 1, 2, 4, 6, 8, 12, 16, 20, and 24 h postendotracheal extubation. CMPSSF scores were compared with the Mann-Whitney Test and proportions of animals that required rescue analgesia and had eaten with a χ2 test. P was set at < 0.05. RESULTS: No rescue analgesia was needed for any animal. Still, significant differences were observed in CMPS-SF scores between CG and PBMTG between 1 and 4 h post-extubation. PBMTG had a significantly higher proportion of animals eating up to the 8 h post-extubation evaluation moment. CONCLUSION: Adding post-surgical photobiomodulation to a standard anesthesia and analgesia protocol reduced CMPS-SF scores and increased the proportion of animals that resumed eating compared to the standard protocol alone.

We evaluated whether a hospital-based anesthesia department can validly use automated intensive care unit (ICU) admission data after elective ambulatory procedures to assess the quality of anesthetic care. Among 13,656 patients, 25 (0.2%) had an unplanned hospital length of stay >1 night and ICU admission. On review, only 1 of the 25 cases (0.007%) had an anesthesia-related complication. The false-positive incidence of anesthetic complications was ≥96% for scheduled ambulatory cases with ICU admission. Therefore, fully automated computerized identification of all unexpected ICU admissions after ambulatory procedures without manual review is an unsuitable (invalid) metric of individual anesthesiologists' clinical performance.

Hutchinson-Gilford Progeria Syndrome (HGPS) is an ultrarare disorder of segmental premature aging that is associated with the development of advanced atherosclerosis and significant cardiovascular and cerebrovascular disease. Treatment with lonafarnib has improved survival in patients with HGPS; however, in extended longitudinal follow-up, there has been an increase in the prevalence of rapidly progressive calcific aortic stenosis. The evolving course of HGPS has prompted reconsideration of conservative management and led to the development of strategies for anatomic treatment. In this case report, we describe the anesthetic management of patients with HGPS undergoing surgical management of aortic stenosis with cardiopulmonary bypass.

OBJECTIVE: To survey anaesthetic practices and attitudes towards veterinary patient safety in Australia. STUDY DESIGN: This was a cross-sectional sample population from Australian veterinary practices, including first opinion small animal, mixed animal and referral small animal practices. The survey included practices' anaesthetic management, monitoring equipment and topics regarding patient safety. RESULTS: Responses were obtained from 310/1700 (18%) veterinary practices, with 208 respondents from small animal practices (67%), 71 mixed animal practices (23%) and 31 referral small animal centres (10%). Overall, 61% of respondents reported always having a dedicated staff member monitoring the anaesthetic, who was most commonly a certified veterinary nurse (89%). In 22% of the practices, some of the staff monitoring an anaesthetic did not have any qualification. Completion of anaesthetic plans for each animal prior to an anaesthetic was reported by 24.5% of respondents and labelling of syringes was completed in 80% of practices. Pulse oximetry (98%) and temperature (88%) were the most common clinical variables monitored. The use of capnography (46%) or an electrocardiogram (48%) was also reported by the respondents. Emergency drugs, airway and ventilation equipment are available in 96%, 88% and 59% of practices, respectively. A defibrillator was available in 11% of practices with only 54% respondents being confident in using it. Of the respondents 60% were aware of anaesthesia safety interventions and clinical guidelines regarding patient safety during anaesthesia. CONCLUSIONS AND CLINICAL RELEVANCE: Despite practices showing a relative improvement over the years in the standard of anaesthesia care, most of them are still not meeting international guidelines. Areas where changes could lead to improved safety practices could include: a trained person dedicated to monitor anaesthesia, pain scoring evaluation in patients recovering from anaesthesia, an increased use of standardised handover checklists, record keeping and an increase in open discussion of adverse events by the veterinary team.

Objective: To estimate the impacts of different anesthetic protocols on the speed and quality of postoperative resuscitation in patients undergoing painless gastroscopy. Methods: This was a prospectively designed randomized control study that included 150 patients who underwent painless gastroscopy in Hainan Cancer Hospital affiliated to Hainan Medical College between April and December of 2023. All the patients, classified as American Society of Aneshesiologists (ASA) Grade â or â ¡, were randomly divided into three groups with different anesthetic protocols, including propofol group (group P), remimazolam group (group R) and remimazolam with flumazenil group (group RF). There were eventually 50 patients in each group. The three groups of patients were compared for their resuscitation time and the time that they stayed in the resuscitation room (addressed as"room time"below). At 10 min and 20 min after resuscitation, each patient was tested for recognition ability (orientation score), walking ability and fine motor skill (including reaction speed, quick-click ability and visual memory), respectively, with possible adverse reactions recorded spontaneously, such as hypotension, dizziness, nausea and vomitus. Results: There were 29 males and 21 females in group P with an average age of (34±6) years, 27 males and 23 females in group R with an average age of (36±8) years, and 26 males and 24 females in group RF with an average age of (33±7) years, respectively. All examinations for each patient were successfully completed with no interruptions. The resuscitation time and room time of group RF were (47±15) s and (26±5) min,respectively, which were both shorter than those in either group R [(489±92) s and (35±6) min] or group P [(196±61) s and (31±7) min] (all P<0.05). The orientation score of patients in group RF at 10 min after resuscitation was (79.0±10.5), which was significantly higher than that in group R (70.0±11.7) (P<0.05). The patients' walking ability score of group RF at 10 min and 20 min after resuscitation were [(23.6±10.8), (48.0±4.5)], which were better than those in group R[(15.4±11.1), (47.6±4.8)] (both P<0.05). The patients' reaction speed and quick-click scores of group RF were [(851.0±150.9), (547.0±114.0) ms] and [(758.0±73.2), (629.0±128.9) ms], which were better than those in either group R [(1 151.0±206.0), (732.0±135.1) ms], [(893.0±110.9), (765.8±125.8) ms] or group P [(985.0±225.3), (613.0±123.2) ms], [(831.0±87.7), (691.0±115.8) ms] (all P<0.05). The incidence rate of hypotension in group P was 18% (9/50), higher than that in either Group R [4% (2/50)] or group RF [2% (1/50)] (all P<0.05). The incidence rates of dizziness, nausea and vomitus were comparable among all the three groups with no statistical differences (all P>0.05). Conclusion: In patients undergoing anesthesia with remazolam, the use of flumazenil can not only shorten the resuscitation time and the time that the patients need to stay in the resuscitation room, but also speed up the recovery of the patients' recognition, walking and fine motor skill abilities.

Coffin-Lowry Syndrome (CLS) is a rare X-linked genetic disorder characterized by growth delays, facial dysmorphisms, and intellectual disabilities. Currently, there are limited published case reports regarding the anesthetic management of patients with CLS. Managing anesthesia for CLS patients can be complex due to difficult airway management. In this case report, we present a patient with CLS who underwent surgical intervention, highlighting the anesthetic considerations encountered throughout the perioperative period. We aim to summarize the difficulties involved in anesthetic management of rare conditions like CLS to improve clinical outcomes for affected individuals.

Scale-free statistics of coordinated neuronal activity, suggesting a universal operating mechanism across spatio-temporal scales, have been proposed as a necessary condition of healthy resting-state brain activity. Recent studies have focused on anesthetic agents to induce distinct neural states in which consciousness is altered to understand the importance of critical dynamics. However, variation in experimental techniques, species, and anesthetics, have made comparisons across studies difficult. Here we conduct a survey of several common anesthetics (isoflurane, pentobarbital, ketamine) at multiple dosages, using calcium wide-field optical imaging of the mouse cortex. We show that while low-dose anesthesia largely preserves scale-free statistics, surgical plane anesthesia induces multiple dynamical modes, most of which do not maintain critical avalanche dynamics. Our findings indicate multiple pathways away from default critical dynamics associated with quiet wakefulness, not only reflecting differences between these common anesthetics but also showing significant variations in individual responses. This is suggestive of a non-trivial relationship between criticality and the underlying state of the subject.

The use of anesthetic agents in the management of fish in fish farming or ornamental fish breeding aims to minimize stress and promote animal welfare. Therefore, this study aims to investigate behavioral, electrocardiographic, and ventilatory characteristics of tambaquis exposed to anesthetic baths with etomidate. The study was conducted with juvenile tambaquis (27.38 ± 3.5g) n = 99, at etomidate concentrations of 2-4 mg.L -1, analyzing induction and anesthetic recovery behavior (experiment I), electrocardiogram (experiment II), and opercular movement (experiment III). Fish exposed to high concentrations of etomidate reached the stage of general anesthesia faster, however, the recovery time was longer, characterizing a dose-dependent relationship. Cardiorespiratory analyzes demonstrated a reduction in heart rate (69.19%) and respiratory rate (40.70%) depending on the concentration of etomidate used during anesthetic induction. During the recovery period, there was cardiorespiratory reversibility to normality. Therefore, etomidate proved to be safe as an anesthetic agent for this species at concentrations of 2 to 3 mg.L -1 for short-term anesthesia, but at higher doses the animals showed slow reversibility of anesthesia in a gradual manner and without excitability. The hemodynamic effect due to the rapid decrease in heart rate includes a negative factor of using higher concentrations of etomidate for Colossome macropomum anesthesia.

The reporting of incidents has a long association with safety in healthcare and anaesthesia, yet many incident reporting systems substantially under-report critical events. Better understanding the underlying reasons for low levels of critical incident reporting can allow such factors to be addressed systematically to arrive at a better reporting culture. However, new forms of automation in anaesthesia also provide powerful new approaches to be adopted in the future.

BACKGROUND: Drug administration errors (DAEs) in anaesthesia are common, the aetiology multifactorial and though mostly inconsequential, some lead to substantial harm. The extend of DAEs remain poorly quantified and effective implementation of prevention strategies sparse. METHOD: A cross-sectional descriptive study was conducted using a peer-reviewed survey questionnaire, circulated to 2217 anaesthetists via a national communication platform. The aim was to determine the self-reported frequency, nature, contributing factors and reporting patterns of DAEs among anaesthesia providers in South Africa. RESULTS: Our cohort had a response rate was 18.9%, with 420 individuals populating the questionnaire. 92.5% of surveyed participants have made a DAE and 89.2% a near-miss. Incorrect route of administration, potentially resulting in serious harm, accounted for 8.2% (n = 23/N = 279) of these errors. DAEs mostly reported in cases involving adult patients (80.5%, n = 243/N = 302), receiving a general anaesthetic (71.8%, n = 216/N = 301), where the drug-administrator prepared the drugs themselves (78.7%, n = 218/N = 277), during normal daytime hours (69.9%, n = 202/N = 289) with good lightning conditions (93.0%, n = 265/N = 285). 26% (n = 80/N = 305) of DAEs involved ampoule misidentification, whilst syringe identification error reported in 51.6% (n = 150/N = 291) of cases. DAEs are often not reported (40.3%, n = 114/N = 283), with knowledge of correct reporting procedures lacking. 70.5% (n = 198/N = 281) of DAEs were never discussed with the patient. CONCLUSIONS: DAEs in anaesthesia remain prevalent. Known error traps continue to drive these incidents. Implementation of system based preventative strategies are paramount to guard against human error. Efforts should be made to encourage scrupulous reporting and training of anaesthesia providers, with the aim of rendering them proficient and resilient to handle these events.

Objective: To explore the feasibility of using ultrasonic convex array probe compressing abdominal wall to increase success rate of external cephalic version (ECV) without anesthesia in full-term and near-term pregnancy. Methods: Totally 190 singleton and non-cephalic presentation pregnant women in 36-39+4 weeks of gestation performed ECV from April 2019 to August 2023 in the First Affiliated Hospital of Nanjing Medical University were analyzed. According to whether use the ultrasound probe compressing fetal breech or not, the pregnant women were divided into two groups: 81 cases in the probe-compressing group (including primipara 61 cases and multipara 20 cases) and 109 cases in the non-probe-compressing group(including primipara 72 cases and multipara 37 cases). Clinical data, ECV related factors and complications were analyzed and compared between the two groups. Results: (1) The overall success rate of ECV was 64.2% (122/190). There was no significant difference in the success rate of ECV between probe-compressing group and non-probe-compressing group [69.1% (56/81) vs 60.6% (66/109), χ2=1.490, P=0.222]. The total vaginal delivery rate after successful ECV was 81.1% (99/122), while 71.1% (54/76) in primipara and 97.8% (45/46) in multipara, respectively. (2) Compare to the non-probe-compressing group, the success rate of ECV in primipara was significantly higher in the probe-compressing group [45.8% (33/72) vs 70.5% (43/61)], but the gestational age was shorter and the height was higher in the probe-compressing group (all P<0.05). The success rate of ECV of multipara in the probe-compressing group (65.0%, 13/20) was lower than that in the non-probe-compressing group (89.2%, 33/37), but there was no significant difference between the two groups (P>0.05). (3) Multivariate logistic regression analysis showed that abdominal wall compressed by ultrasound probe (OR=2.601, 95%CI: 1.113-6.075; P=0.027) and amniotic fluid index (AFI; OR=1.010, 95%CI: 1.001-1.020; P=0.028) were positive factors for the successful rate of ECV in primipara pregnant women. (4) The main complication of ECV was transient fetal heart rate reduction (8.9%,17/190), the incidence in the probe-compressing group was significantly higher than that in the non-probe-compressing group [14.8% (12/81) vs 4.6% (5/109); χ2=5.967, P=0.015]. No statistical differences were found in rates of complications between the ECV successful and unsuccessful pregnant women, and between probe-compressing and non-probe-compressing groups (all P>0.05). No adverse maternal and neonatal outcomes related to ECV were observed. Conclusions: The ultrasonic convex array probe compressing could significantly improve the success rate of ECV in primipara without increasing the incidence of adverse maternal and fetal outcomes. The success rate of ECV in primipara is influenced by AFI and operation mode.

To explore the application efficacy and significance of deep learning in anesthesia management for gastrointestinal tumors (GITs) surgery, 80 elderly patients with GITs who underwent surgical intervention at our institution between January and September 2021 were enrolled. According to the preoperative anesthesia management methodology, patients were rolled into a control (Ctrl) group (using 10 mg dexamethasone 1-2 hours before surgery) and an experimental (Exp) group (using a deep learning-based anesthesia monitoring system on the basis of the Ctrl group), with 40 cases in each group. A comprehensive comparative analysis was performed between the two cohorts, encompassing postoperative cognitive evaluations, Montreal Cognitive Assessment (MoCA) scores, gastrointestinal functionality, serum biomarkers (including interleukin (IL)-6, C-reactive protein (CRP), and cortisol levels), length of hospitalization, incidence of complications, and other pertinent metrics. The findings demonstrated that anesthesia monitoring facilitated by deep learning algorithms effectively assessed the anesthesia state of patients. Compared to the Ctrl group, patients in the Exp group showed significant differences in cognitive assessments (word recall, number connection, number coding) (P<0.05). Additionally, the Exp group exhibited a notably increased MoCA score (25.3±2.4), significantly shorter time to first flatus postoperatively (35.8±13.7 hours), markedly reduced postoperative pain scores, significantly shortened time to tolerate a liquid diet postoperatively (19.6±5.2 hours), accelerated recovery of serum-related indicators, and a significantly decreased mean length of hospital stay (11.4±3.2 days) compared to the Ctrl group. In summary, administering dexamethasone under the anesthesia management of GITs surgery based on gradient boosting decision tree (GBDT) and pharmacokinetics pharmacodynamics (PKPD) models can promote patient recovery, reduce the incidence of postoperative cognitive impairment (POCD), and improve patient prognosis.

OBJECTIVES: Currently, there remains debate regarding the optimal anesthesia approach for patients undergoing intra-arterial therapy for acute ischemic stroke. Therefore, we conducted a comparative analysis to assess the effects of general anesthesia versus non general anesthesia on patient outcomes. METHODS: The research methodology entailed comprehensive searches of prominent databases such as the Cochrane Library, PubMed, Scopus, and Web of Science, covering the period from January 1, 2010, to March 1, 2024. Data synthesis employed techniques like risk ratio or standardized mean difference, along with 95% confidence intervals. The study protocol was prospectively registered with PROSPERO (CRD42024523079). RESULTS: A total of 27 trials and 12,875 patients were included in this study. The findings indicated that opting for non-general anesthesia significantly decreased the risk of in-hospital mortality (RR, 1.98; 95% CI: 1.50 to 2.61; p<0.00001; I2 = 20%), as well as mortality within three months post-procedure (RR, 1.24; 95% CI: 1.15 to 1.34; p<0.00001; I2 = 26%), while also leading to a shorter hospitalization duration (SMD, 0.24; 95% CI: 0.15 to 0.33; p<0.00001; I2 = 44%). CONCLUSION: Ischemic stroke patients who undergo intra-arterial treatment without general anesthesia have a lower risk of postoperative adverse events and less short-term neurological damage. In routine and non-emergency situations, non-general anesthetic options may be more suitable for intra-arterial treatment, offering greater benefits to patients. In addition to this, the neuroprotective effects of anesthetic drugs should be considered more preoperatively and postoperatively.

Total endovascular aortic arch repair is nowadays a promising alternative for selected patients with aortic arch disease. These endovascular procedures are technically challenging and require a diligent planning among all members of a multidisciplinary "Aorta Team" integrating cardiovascular anesthesiologists. In fact, endovascular aortic arch repair is a major challenge for anesthesiologists because of the risk of hemodynamic instability, cerebral events and acute kidney injury. In order to achieve the success, it is fundamental to discuss each patient in an individual basis, including perioperative management and care, and to be aware of surgical steps and their potential complications. Considering our previous experience with endovascular thoracoabdominal aortic surgery, we herein summarize our experience with anesthetic management of patients who underwent total endovascular aortic arch repair and its principal outcomes.

BACKGROUND: Patient safety is essential in small animal anaesthesia. This study aimed to assess anaesthesia-related deaths in cats worldwide, identify risk and protective factors and provide insights for clinical practice. METHODS: A prospective multicentre cohort study of 14,962 cats from 198 veterinary centres across different countries was conducted. Data on anaesthesia-related deaths, from premedication up to 48 hours postextubation, were collected. Logistic regression was used to analyse patient demographics, American Society of Anesthesiologists (ASA) classification, procedure type and anaesthetic drugs. RESULTS: The anaesthesia-related mortality was 0.63%, with 74.5% of deaths occurring postoperatively. Cats with cachexia, a higher ASA status or who underwent abdominal, orthopaedic/neurosurgical or thoracic procedures exhibited elevated mortality. Mechanical ventilation use was associated with increased mortality. Mortality odds were reduced by the use of alpha2-agonist sedatives, pure opioids in premedication and locoregional techniques. LIMITATIONS: Limitations include non-randomised sampling, potential biases, unquantified response rates, subjective death cause classification and limited variable analysis. CONCLUSIONS: Anaesthetic mortality in cats is significant, predominantly postoperative. Risk factors include cachexia, higher ASA status, specific procedures and mechanical ventilation. Protective factors include alpha2-agonist sedatives, pure opioids and locoregional techniques. These findings can help improve anaesthesia safety and outcomes. However, further research is required to improve protocols, enhance data quality and minimise risks.
