UNASSIGNED: Ischemic cerebrovascular disease (ICVD) is a serious health problem in which brain tissue suffers from hypoxic damage due to obstruction in cerebral vessels. Mechanical thrombectomy is a commonly used method in the treatment of these patients. However, the effects of local anesthesia (LA) and conscious sedation (CS) during thrombectomy are still unclear. We evaluated whether there was a relationship between the two anesthesia regimens in terms of 90-day modified Rankin Scale (mRS) scores.
UNASSIGNED: In this study, a retrospective observational study was conducted to evaluate the effects of LA and CS used during mechanical thrombectomy in four comprehensive stroke centers among ICVD patients. Patients were divided into the LA group and the CS group. Statistical analysis was performed before and after 1:1 matching under propensity score matching (PSM) analysis. The primary outcome measure was an mRS score of 0-2 at 90 days. Secondary outcomes were procedure times, recanalization rates, symptomatic and asymptomatic hemorrhage rates, and procedural complications.
UNASSIGNED: A total of 193 patients (118 patients with LA and 75 patients with CS) were included in the final analysis before PSM. After 1:1 PSM, 98 patients-49 patients from each group-were included in the study. There was no difference in clinical outcomes between the LA- and CS-applied groups (p = 0.543). When blood pressure (BP) values at follow-up after endovascular treatment (EVT) were compared, the lowest systolic and lowest diastolic BP were found to be lower in the CS group (p = 0.001 and p = 0.009). There was no significant difference between the two groups in terms of recanalization rates, symptomatic intracranial hemorrhage (sICH) rates, 90-day mRS, and procedure-related complication rates (p = 0.617, p = 0.274, p = 0.543, and p = 1.000).
UNASSIGNED: This study did not reveal the superiority of CS applied during EVT on 90-day mRS, sICH, recanalization rates, or procedural complications. However, the risk of developing hypotension during the CS application was found to be high.

Purpose: To compare the degree of acceptance of behavior guidance techniques (BGT) in pediatric dentistry between American and Colombian parents. Methods: American parents (n=150) and Colombian parents (n=150) of children between three and 12 years of age undergoing pediatric dental treatment participated in this multicenter cross-sectional study. Parents viewed a video depicting 10 BGTs approved by the American Academy of Pediatric Dentistry and rated their acceptance on a visual analog scale. Differences in the degree of acceptance were analyzed using quantile regression analysis. The level of significance was set at five percent. Results: American parents generally demonstrated higher median acceptance scores across various BGTs compared to Colombian parents (P<0.05). American parents exhibited higher acceptance levels of tell-show-do, voice control, non-verbal communication, positive reinforcement, distraction, presence/absence of parents and nitrous oxide, with statistically significant differences noted. American parents also displayed higher acceptance scores for advanced techniques such as protective stabilization, conscious sedation and general anesthesia. Conclusion: American parents consistently exhibited higher acceptance BGTs, suggesting variations in cultural attitudes toward pediatric dental care between the two groups.

UNASSIGNED: The effectiveness of daily sedation interruption (DSI, defined as temporary interruption of sedation) has yet to be demonstrated in critically ill pediatric patients.
UNASSIGNED: To compare the clinical outcomes of DSI vs continuous intravenous (IV) sedation in patients receiving invasive mechanical ventilation (MV) support in the pediatric intensive care unit (PICU).
UNASSIGNED: A systematic search for studies was conducted using predefined keywords and Medical Subject Headings in 5 major databases (PubMed, Embase, Web of Science, CINAHL [Cumulated Index to Nursing and Allied Health Literature], and Cochrane Central Register of Controlled Trials) from database inception to October 31, 2023.
UNASSIGNED: Retrospective and prospective observational studies, randomized clinical trials (RCTs), and systematic reviews were assessed for inclusion. Studies were eligible if they compared DSI to continuous IV sedation in patients aged 18 years or younger requiring MV in the PICU.
UNASSIGNED: Study characteristics, including the types of sedation, sedation protocols, and clinical outcomes, were extracted. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting guideline was followed. A random-effects model was used to pool results from articles for the meta-analysis.
UNASSIGNED: The primary outcomes of interest were duration of MV and length of PICU stay. Secondary outcomes included total sedative dose requirement, adverse events (eg, complications associated with MV, withdrawal, and delirium), and mortality.
UNASSIGNED: A total of 6 RCTs with 2810 pediatric patients (1569 males [55.8%]; mean age, 26.5 [95% CI, 15.0-37.9] months) were included in the final analysis; patients had a mean PRISM (Pediatric Risk of Mortality) score of 13.68 (95% CI, 10.75-16.61). Compared with continuous IV sedation, DSI was associated with a reduction in length of PICU stay (5 studies, n = 2770; mean difference [MD], -1.45 [95% CI, -2.75 to -0.15] days; P = .03]. There was no difference in MV duration (5 studies, n = 2750; MD, -0.93 [95% CI, -1.89 to 0.04] days; P = .06), total doses of midazolam (3 studies, n = 191; MD, -1.66 [95% CI, -3.95 to 0.63] mg/kg) and morphine used (2 studies, n = 189; MD, -2.63 [95% CI, -7.01 to 1.75] mg/kg), or adverse events (risk ratio [RR], 1.03 [95% CI, 0.74-1.42]; P = .88). There was no difference in mortality between patients exposed vs not exposed to DSI (RR, 0.89 [95% CI, 0.55-1.46]; P = .65).
UNASSIGNED: This systematic review and meta-analysis found that use of DSI in pediatric patients was associated with reduced length of PICU stay with no increase in adverse events. Further research is needed to ascertain whether this strategy is associated with improved neurodevelopmental outcomes in PICU survivors.

OBJECTIVE: Catheter ablation (CA) is a well-established treatment option for atrial fibrillation (AF), where sedation and analgesia are pivotal for patient comfort and lesion formation. The impact of anaesthesia type on AF recurrence rates remains uncertain. This study aimed to examine AF recurrence rates depending on conscious sedation (CS) versus general anaesthesia (GA) during CA.
METHODS: Utilizing nationwide data from The Danish healthcare registries, we conducted this cohort study involving adults (≥18 years) undergoing first-time CA for AF between 2010 and 2018. Patients were categorized by anaesthesia type (CS or GA), with the primary endpoint being AF recurrence, defined by a composite endpoint of either antiarrhythmic drugs (AAD) prescriptions, AF-related hospital admissions, electrical cardioversions, or AF re-ablation. The impact of anaesthesia type was evaluated using multivariable Cox proportional hazards analysis.
RESULTS: The study cohort comprised 7,957 (6,421 CS and 1,536 GA) patients. Persistent AF, hypertension, and heart failure, as well as use of AAD were more prevalent in the GA group. Cumulative incidences of recurrent AF were higher in the CS group at one year (46% vs 37%) and at five years (68 % vs 63%). Multivariate analysis revealed CS as significantly associated with increased risk of AF recurrence at five-year follow-up (HR 1.26 (95% CI: 1.15-1.38)), consistent across paroxysmal and persistent AF subtypes.
CONCLUSIONS: This nationwide cohort study suggests a higher risk of AF recurrence with CS during CA compared to GA. These results advocate for considering GA as the preferred anaesthesia type for improved CA outcomes.

Procedural sedation and analgesia is an essential activity in the emergency department for managing pain and anxiety during a variety of medical procedures. Various pharmacotherapy options, including opioid analgesics, antiemetics, anticholinergics, sedatives, and ketamine have been utilized, all with their unique efficacy and safety profiles. This review highlights the challenges associated with using certain agents and discusses emerging trends such as the use of newer synthetic opioids and the expanding use of dexmedetomidine. Overall, the selection of the optimal agents for procedural sedation and analgesia should be guided based on the unique characteristics of each agent tailored to the needs of the specific procedure, along with consideration for individual patient characteristics.

Gastroenterology nurses working across a variety of clinical settings are responsible for periprocedural monitoring during moderate to deep procedural sedation and analgesia (PSA) to identify signs of respiratory compromise and intervene to prevent cardiorespiratory events. Pulse oximetry is the standard of care for respiratory monitoring, but it may delay or fail to detect abnormal ventilation during PSA. Continuous capnography, which measures end-tidal CO2 as a marker of alveolar ventilation, has been endorsed by a number of clinical guidelines. Large clinical trials have demonstrated that the addition of continuous capnography to pulse oximetry during PSA for various gastroenterological procedures reduces the incidence of hypoxemia, severe hypoxemia, and apnea. Studies have shown that the cost of adding continuous capnography is offset by the reduction in adverse events and hospital length of stay. In the postanesthesia care unit, continuous capnography is being evaluated for monitoring opioid-induced respiratory depression and to guide artificial airway removal. Studies are also examining the utility of continuous capnography to predict the risk of opioid-induced respiratory depression among patients receiving opioids for primary analgesia. Continuous capnography monitoring has become an essential tool to detect early signs of respiratory compromise in patients receiving PSA during gastroenterological procedures. When combined with pulse oximetry, it can help reduce cardiorespiratory adverse events, improve patient outcomes and safety, and reduce health care costs.

On July 1, 2021, cannabis became legal in Virginia for adults 21 years of age and older. Cannabis consumption may have significant implications for outcomes related to medical care, including procedural sedation. The purpose of this study was to determine whether self-reported cannabis consumption has any relationship to sedation medication requirements during endoscopic procedures. A retrospective analysis was conducted to examine two groups of surgical patients (self-reported cannabis use versus self-reported non-cannabis use) at a community hospital in the mid-Atlantic region. Results demonstrate that there were no significant differences between groups for either Time to Aldrete ≥8 (p = .486) or Time to Meet Phase II Criteria (p = .762). Equivalent recovery times for both groups may be an indicator that comparable sedation levels were maintained, despite the increased propofol requirements of the cannabis group. Open conversations to establish patient use of cannabis products prior to procedural sedation is important for determining appropriate plans of care related to risk factors and medication dosage requirements during endoscopic evaluations.

BACKGROUND: Routine outpatient endoscopy is performed across a variety of outpatient settings. A known risk of performing endoscopy under moderate sedation is the potential for over-sedation, requiring the use of reversal agents. More needs to be reported on rates of reversal across different outpatient settings. Our academic tertiary care center utilizes a triage tool that directs higher-risk patients to the in-hospital ambulatory procedure center (APC) for their procedure. Here, we report data on outpatient sedation reversal rates for endoscopy performed at an in-hospital APC vs at a free-standing ambulatory endoscopy digestive health center (AEC-DHC) following risk stratification with a triage tool.
OBJECTIVE: To observe the effect of risk stratification using a triage tool on patient outcomes, primarily sedation reversal events.
METHODS: We observed all outpatient endoscopy procedures performed at AEC-DHC and APC from April 2013 to September 2019. Procedures were stratified to their respective sites using a triage tool. We evaluated each procedure for which sedation reversal with flumazenil and naloxone was recorded. Demographics and characteristics recorded include patient age, gender, body mass index (BMI), American Society of Anesthesiologists (ASA) classification, procedure type, and reason for sedation reversal.
RESULTS: There were 97366 endoscopic procedures performed at AEC-DHC and 22494 at the APC during the study period. Of these, 17 patients at AEC-DHC and 9 at the APC underwent sedation reversals (0.017% vs 0.04%; P = 0.06). Demographics recorded for those requiring reversal at AEC-DHC vs APC included mean age (53.5 ± 21 vs 60.4 ± 17.42 years; P = 0.23), ASA class (1.66 ± 0.48 vs 2.22 ± 0.83; P = 0.20), BMI (27.7 ± 6.7 kg/m2 vs 23.7 ± 4.03 kg/m2; P = 0.06), and female gender (64.7% vs 22%; P = 0.04). The mean doses of sedative agents and reversal drugs used at AEC-DHC vs APC were midazolam (5.9 ± 1.7 mg vs 8.9 ± 3.5 mg; P = 0.01), fentanyl (147.1 ± 49.9 μg vs 188.9 ± 74.1 μg; P = 0.10), flumazenil (0.3 ± 0.18 μg vs 0.17 ± 0.17 μg; P = 0.13) and naloxone (0.32 ± 0.10 mg vs 0.28 ± 0.12 mg; P = 0.35). Procedures at AEC-DHC requiring sedation reversal included colonoscopies (n = 6), esophagogastroduodenoscopy (EGD) (n = 9) and EGD/colonoscopies (n = 2), whereas APC procedures included EGDs (n = 2), EGD with gastrostomy tube placement (n = 1), endoscopic retrograde cholangiopancreatography (n = 2) and endoscopic ultrasound\'s (n = 4). The indications for sedation reversal at AEC-DHC included hypoxia (n = 13; 76%), excessive somnolence (n = 3; 18%), and hypotension (n = 1; 6%), whereas, at APC, these included hypoxia (n = 7; 78%) and hypotension (n = 2; 22%). No sedation-related deaths or long-term post-sedation reversal adverse outcomes occurred at either site.
CONCLUSIONS: Our study highlights the effectiveness of a triage tool used at our tertiary care hospital for risk stratification in minimizing sedation reversal events during outpatient endoscopy procedures. Using a triage tool for risk stratification, low rates of sedation reversal can be achieved in the ambulatory settings for EGD and colonoscopy.

Climate change represents an urgent global threat. Without action, rising temperatures resulting from human activity will increasingly affect our health and wellbeing through changing patterns of disease, extreme weather events and availability of resources. Expedient decarbonisation of the UK economy is an ambitious goal to which we must all contribute.The NHS aims to be the world\'s first net-zero health service and reach carbon-neutral status by 2040. Dental services are particularly resource-intensive. Some dental anxiety management techniques have a disproportionately high impact on the environment relative to their usage. Inhalation sedation with nitrous oxide is one such example.Nitrous oxide is a greenhouse gas almost 300 times more potent than carbon dioxide, but its utility to facilitate dental treatment for anxious and vulnerable patients is well-documented. This paper balances the health utility with environmental and social harm of continuing to use nitrous oxide and suggests evidence-based methods we can apply to limit the environmental impact of sedation services.
