Background: This study aimed to determine the 50% effective dose of remimazolam co-administered with remifentanil for loss of consciousness in men and women as well as to investigate whether there are between-sex differences. Methods: Using a modified Dixon's up-and-down allocation approach, we sequentially enrolled male and female patients aged 19–60 years with American Society of Anesthesiologists class I or II who were scheduled for robotic surgery. For both sexes, the starting remimazolam dose was 0.15 mg/kg, with a step size of 0.05 mg/kg. After achievement of a target effect-site concentration 2.0 ng/ml of remifentanil, and administration of a bolus dose of remimazolam, we assessed whether adequate loss of consciousness (defined as a Modified Observer's Assessment of Alertness/Sedation scale score < 2 within 2 min) was achieved. Results: We included 22 male and 22 female patients. Based on Dixon's up-and-down method, the 50% effective dose of remimazolam (mean ± standard error) was 0.13 ± 0.01 mg/kg and 0.17 ± 0.01 mg/kg in the male and female groups, respectively (P = 0.34). Isotonic regression analysis revealed that the 95% effective dose (95% confidence interval) was 0.19 (0.18–0.20) mg/kg in the male group and 0.29 (0.29–0.30) mg/kg in the female group. Conclusions: There was no between-sex difference in the 50% effective dose of remimazolam for loss of consciousness; however, the 95% effective dose was significantly higher in female patients than in male patients. Trial registration: This study protocol was registered at Clinical Research Information Service (CRIS No. KCT0007951, 02/12/2022). [ABSTRACT FROM AUTHOR]

Introduction: Percutaneous ultrasound-guided radiofrequency ablation (RFA) is a well-studied treatment option for locally non-advanced hepatocellular carcinoma (HCC) and colorectal liver metastases (CRLMs). Sedation is of crucial interest as it enables safe and pain-free procedures. Whether the type of sedation has an impact on procedural outcome is still not well investigated. Methods: We retrospectively collected data on patients undergoing liver RFA for various oncological conditions. Procedures were conducted in a non-operating room anesthesia (NORA) setting. Procedural-related complications and short-term oncological outcomes were analyzed. Results: Thirty-five patients (mean age 71.5 y, 80% male) were treated for HCC (26), CRLM (6) and gastric cancer metastases (3). Mean lesion size was 21 mm (SD ± 10.1 mm), and the most common tumor localization was the right hepatic lobe. RFA was performed in a step-up sedation approach, with subcutaneous lidocaine injection prior to needle placement and subsequent deep sedation during ablation. No anesthesia-related early or late complications occurred. One patient presented with pleural effusion due to a large ablation zone and was treated conservatively. Local tumor-free survival after 1 and 6 months was 100% in all cases where a curative RFA approach was intended. Conclusions: NORA for liver RFA comes with high patient acceptance and tolerance, and optimal postoperative outcomes and oncologic results. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Over the past 4 years, aesthetic surgery, notably liposuction, has substantially increased. Tumescent liposuction, a popular technique, has two variants—true tumescent liposuction (TTL) and semi-tumescent liposuction. While TTL reduces risks, it has limitations. There is no literature reported on semi-tumescent liposuction under deep sedation using the propofol–ketamine protocol, which is proposed as a potentially safe alternative. Methods: The retrospective analysis covered 8 years and included 3094 patients performed for tumescent liposuction under deep sedation, utilizing the propofol–ketamine protocol. The evaluation of patient safety involved an examination of potential adverse events with a specific focus on respiratory issues related to sedation, including instances of mask ventilation. Results: Among the 3094 cases, no fatalities were recorded. Noteworthy events included 43 mask ventilation instances, primarily occurring in the initial 10 min. Twelve cases experienced surgery cancellation due to various factors, including respiratory issues. Three patients were transferred to upper-level hospitals, while another three required blood transfusions. Vigilant management prevented significant complications, and other adverse events like venous thromboembolism (VTE), fat embolism, severe lidocaine toxicity, and so on were not observed. Conclusions: The analysis of 3094 tumescent liposuction cases highlighted the overall safety profile of the propofol–ketamine protocol under deep sedation. The scarcity of severe complications underscores its viability. The study emphasizes the significance of thorough preoperative assessments, careful patient selection, and awareness of potential complications. Prompt interventions, particularly in addressing sedation-related respiratory issues, further contribute to positive outcomes for patients.

Objective To analyze the risk factors for prolonged sedation recovery time in epileptic children. Methods A cross-sectional trial was conducted on the epileptic children who underwent electroencephalography (EEG) with oral administration of chloral hydrate and nasal dexmedetomidine for sedation in our hospital from November 2019 to December 2022. Their general information and sedation and medication data were collected. Prolonged sedation recovery time was defined as beyond the 75th percentile of awaking time, and then the children were divided into recovery time ≤1 h group and >1 h group. Univariate and multivariable logistic regression analyses were used to identify the risk factors for recovery time in these children. Results A total of 1 346 children were enrolled, including 805 males and 541 females, with a median age of 6.03 (4.42, 8.56) years. There were 986 children assigned into recovery time ≤1 h group and 360 ones into recovery time >1 h group. Univariate analysis showed that significant differences were observed in the proportions of age < 1 year (0.8% vs 2.2%, P=0.046), sedation more than 3 times (35.8% vs 42.2%, P=0.031), and treated with multiple antiepileptic drugs (AEDs) (25.5% vs 36.9%, P < 0.001) between the 2 groups. Multivariable logistic regression analysis indicated that age < 1 year (OR=2.943, 95%CI: 1.063~8.142, P=0.034), sedation times ≥3 (OR=1.287, 95%CI: 1.003~1.649, P=0.047) and multiple use of AEDs (OR=1.718, 95%CI: 1.325~2.223, P < 0.001) were risk factors for prolonged recovery time. Conclusion Age < 1 year, sedation times ≥3 and multiple use of AEDs are risk factors for prolonged sedation recovery time in epileptic children undergoing EEG after oral chloral hydrate and nasal dexmedetomidine.

Abstract Background The practice of continuous palliative sedation until death is the subject of much medical and ethical debate, which is reflected in the inconsistency that persists in the literature regarding the definition and indications of palliative sedation. Aim This study aims to gain a better understanding of palliative care clinicians’ experiences with continuous palliative sedation. Design We conducted a qualitative study based on focus group discussions. Setting/participants We conducted six focus groups with a total of 28 palliative care clinicians (i.e., 15 nurses, 12 physicians, and 1 end-of-life doula) from diverse care settings across Canada, where assisted dying has recently been legalized. Results An interpretative phenomenological analysis was used to consolidate the data into six key themes: responding to suffering; grappling with uncertainty; adapting care to ensure ongoing quality; grounding clinical practice in ethics; combining medical expertise, relational tact, and reflexivity; and offering an alternative to assisted death. Conclusions Interaction with the patient’s family, uncertainty about the patient’s prognosis, the concurrent practice of assisted dying, and the treatment of existential suffering influence the quality of sedation and indicate a lack of clear palliative care guidelines. Nevertheless, clinicians exhibit a reflective and adaptive capacity that can facilitate good practice.

Abstract Background Proper sedation of patients, particularly elderly individuals, who are more susceptible to sedation-related complications, is of significant importance in endoscopic retrograde cholangiopancreatography (ERCP). This study aims to assess the safety and efficacy of a low-dose combination of midazolam, alfentanil, and propofol for deep sedation in elderly patients undergoing ERCP, compared to a group of middle-aged patients. Methods The medical records of 610 patients with common bile duct stones who underwent elective ERCP under deep sedation with a three-drug regimen, including midazolam, alfentanil, and propofol at Shandong Provincial Third Hospital from January 2023 to September 2023 were retrospectively reviewed in this study. Patients were categorized into three groups: middle-aged (50–64 years, n = 202), elderly (65–79 years, n = 216), and very elderly (≥ 80 years, n = 192). Intraoperative vital signs and complications were compared among these groups. Results The three groups showed no significant difference in terms of intraoperative variation of systolic blood pressure (P = 0.291), diastolic blood pressure (P = 0.737), heart rate (P = 0.107), peripheral oxygen saturation (P = 0.188), bispectral index (P = 0.158), and the occurrence of sedation-related adverse events including hypotension (P = 0.170) and hypoxemia (P = 0.423). Conclusion The results suggest that a low-dose three-drug regimen consisting of midazolam, alfentanil, and propofol seems safe and effective for deep sedation of elderly and very elderly patients undergoing ERCP procedures. However, further studies are required to verify these findings and clarify the benefits and risks of this method.

OBJECTIVE The Society of Critical Care Medicine released the first guideline for the prevention and management of pain, agitation, neuromuscular blockade, and delirium in critically ill pediatric patients but offered conditional recommendations for sedation practices and monitoring during neuromuscular blockade. This study aimed to characterize sedation practices, patient awareness, and depth of blockade with neuromuscular blocking agent (NMBA) infusion administration in a single pediatric and cardiac intensive care unit. METHODS This retrospective chart review of critically ill pediatric patients queried orders for continuous infusion NMBA. Analgosedation agent(s), dose, and dose changes were assessed, along with depth of blockade monitoring via Train of Four (TOF) and awareness via Richmond Agitation and Sedation Scale (RASS). RESULTS Thirty-one patients were included, of which 27 (87%) had a documented sedation agent infusing at time of NMBA initiation and 17 patients (54%) were receiving analgesia. The most common agents used were rocuronium (n = 28), dexmedetomidine (n = 23), and morphine (n = 14). RASS scores were captured in all patients; however, 9 patients (29%) had recorded positive scores and 1 patient (3%) never achieved negative scores. TOF was only captured for 11 patients (35%), with majority of the scores being 0 or 4. CONCLUSIONS Majority of the study population did not receive recommended depth of blockade monitoring via TOF. Similarly, RASS scores were not consistent with deep sedation in half of the patients. The common use of dexmedetomidine as a single sedation agent calls into question the appropriateness of current sedation practices during NMBA continuous infusions. [ABSTRACT FROM AUTHOR]

Aim: Knowledge of risk factors may provide strategies to reduce the high burden of delirium in intensive care unit (ICU) patients. We aimed to compare the risk of delirium after deep sedation with propofol versus midazolam in ICU patients. Methods: In this prospective cohort study, ICU patients who were in an unarousable state for ≥24 h due to continuous sedation with propofol and/or midazolam were included. Patients admitted ≤24 h, those with an acute neurological disorder and those receiving palliative sedation were excluded. ICU patients were assessed daily for delirium during the 7 days following an unarousable state due to continuous sedation. Results: Among 950 included patients, 605 (64%) subjects were delirious during the 7 days after awaking. The proportion of subsequent delirium was higher after midazolam sedation (152/207 [73%] patients) and after both propofol and midazolam sedation (257/377 [68%] patients), compared to propofol sedation only (196/366 [54%] patients). Midazolam sedation (adjusted cause‐specific hazard ratio [adj. cause‐specific HR] 1.32, 95% confidence interval [CI] 1.05‐1.66) and propofol and midazolam sedation (adj. cause‐specific HR 1.29, 95% CI 1.06‐1.56) were associated with a higher risk of subsequent delirium compared to propofol sedation only. Conclusion: This study among sedated ICU patients suggests that, compared to propofol sedation, midazolam sedation is associated with a higher risk of subsequent delirium. This risk seems more apparent in patients with high cumulative midazolam intravenous doses. Our findings underpin the recommendations of the Society of Critical Care Medicine Pain, Agitation/sedation, Delirium, Immobility (rehabilitation/mobilization), and Sleep (disruption) guidelines to use propofol over benzodiazepines for sedation in ICU patients.

Purpose: We aim to assess the impact of the exposure to deep versus light sedation by a critical care transport agency during prehospital and interhospital transport on hospital sedation levels, medication exposure, and outcomes of mechanically ventilated patients. Materials and Methods: Retrospective cohort review of mechanically ventilated adult critical care transport patients from January 1, 2019, to March 11, 2020, who arrived at an academic medical center. The primary outcome was the correlation of deep sedation during transport with deep sedation within the first 48 h of hospitalization (defined as Richmond Agitation Sedation Scale [RASS] −3 to −5). The secondary outcomes were duration of mechanical ventilation, hospital length of stay, intensive care unit (ICU) length of stay, inpatient mortality, delirium within 48 h, and coma within 48 h. Results: One hundred and ninety-eight patients were included, of whom 183 (92.4%) were deeply sedated during transport which persisted through the first 48 h of hospital care. Deep sedation during transport was not correlated with deep sedation in the hospital within the first 48 h (OR 2.41; 95% CI, 0.48-12.02). There was no correlation with hospital length of stay, ICU length of stay, duration of mechanical ventilation, or hospital mortality. Deep sedation during transport was not correlated with delirium or coma within the first 48 h of hospitalization. There was a negligible correlation between final transport RASS and initial hospital RASS which did not differ based on the lapsed time from handoff (<1 h corr. coeff. 0.23; ≥1 h corr. coeff. 0.25). Conclusions: Deep sedation was observed during critical care transport in this cohort and was not correlated with deep sedation during the first 48 h of hospitalization. The transition of care between the transport team and the hospital team may be an opportunity to disrupt therapeutic momentum and re-evaluate sedation decisions. [ABSTRACT FROM AUTHOR]

This study aimed to categorize contrast media images associated with epidural, subdural, and combined epidural–subdural anesthesia in patients who had undergone fluoroscopy-guided epidural anesthesia using contrast media combined with monitored anesthesia care (MAC) targeted at deep sedation, incorporating capnography over 5 years. Additionally, a correlation was established between the anesthetic effects and radiographic findings according to the categorized imaging appearances. This study included 628 patients who underwent endoscopic, open, or fusion surgery under epidural anesthesia at Nanoori Hospital in Gangnam between March 2018 and September 2023. Fluoroscopy-guided epidural anesthesia using contrast media combined with MAC and capnography was used. The dataset included detailed radiographic imaging, nursing, and anesthesia records. Distinct patterns of anesthesia administration were observed, with 49%, 19.6%, and 31% of patients receiving epidural, subdural, and combined epidural–subdural anesthesia, respectively. The incidence and duration of motor block were significantly different among the three groups. Additionally, subdural anesthesia displayed a higher incidence of motor block and a prolonged motor deficit duration than epidural anesthesia. Fluoroscopic guidance using a contrast medium for epidural and subdural anesthesia ensures precise space identification and prevents serious anesthetic complications. Our findings suggest the potential to achieve stable anesthesia, particularly using subdural and combined epidural–subdural anesthesia. [ABSTRACT FROM AUTHOR]

Background: Terminological problems concerning sedation in palliative care and consequences for research and clinical decision making have been reported frequently. Objectives: To gather data on the application of definitions of sedation practices in palliative care to clinical cases and to analyze implications for high-quality definitions. Design: We conducted an online survey with a convenience sample of international experts involved in the development of guidelines on sedation in palliative care and members of the European Association for Palliative Care (EAPC). Participants were asked to apply four published definitions to four case vignettes. Data were analyzed using descriptive statistics. Results: A total of 32 experts and 271 EAPC members completed the survey. The definitions were applied correctly in n = 2200/4848 cases (45.4%). The mean number of correct applications of the definitions (4 points max.) was 2.2 ± 1.14 for the definition of the SedPall study group, 1.8 ± 1.03 for the EAPC definition, 1.7 ± 0.98 for the definition of the Norwegian Medical Association, and 1.6 ± 1.01 for the definition of the Japanese Society of Palliative Medicine. The rate of correct applications for the 16 vignette-definition pairs varied between 70/303 (23.1%) and 227/303 (74.9%). The content of definitions and vignettes together with free-text comments explains participants' decisions and misunderstandings. Conclusions: Definitions of sedation in palliative care are frequently incorrectly applied to clinical case scenarios under simplified conditions. This suggests that clinical communication and research might be negatively influenced by misunderstandings and inconsistent labeling or reporting of data.

Purpose: The optimal agent for deep sedation in patients undergoing continuous infusion (CI) neuromuscular blocking agent (NMBA) use for acute respiratory distress syndrome (ARDS) is unknown. The purpose of this study is to compare the efficacy and safety of propofol and midazolam in ARDS patients requiring CI NMBA. Methods: A multi-center, retrospective study was performed in mechanically ventilated (MV) adult patients requiring CI NMBA for management of ARDS. The primary outcome was to compare the time to liberation from MV in patients sedated with propofol vs midazolam. Results: In the 109 patients included, there was no difference in time to MV liberation with propofol as compared to midazolam (121 hr [Interquartile range (IQR) 67 195] vs 98 hr [IQR 48, 292], P =.72). Median time to sedation emergence after NMBA discontinuation was shorter in patients receiving propofol (12.9 hr [IQR 19.8, 72.5] vs 31.5 hr [IQR 6.4, 34.6], P <.01). There were no significant differences in time to therapeutic sedation, ICU stay, mortality, and adverse events. Conclusion: Propofol may be an effective and safe alternative to midazolam for patients undergoing CI NMBA for ARDS. Additionally, patients receiving propofol may have a quicker return to light sedation after NMBA discontinuation. [ABSTRACT FROM AUTHOR]

Oropharyngeal airways (OPA) or nasopharyngeal airways (NPA) sometimes require chin-lift or jaw-thrust (CLJT) maneuvers to relieve airway obstruction which creates the burden of continuous hands-on care by the anesthesia provider. A new distal pharyngeal airway device (DPA) was used on 63 successive ambulatory surgery patients to assess the frequency of patients requiring manual CLJT maneuvers to prevent airway obstruction. Results were then compared with a contemporaneous group of patients who had used OPA or NPA devices for similar procedures. Patients using the DPA had a 38.5% lower rate of CLJT maneuvers compared with the combined OPA/NPA groups (22.2% of 63 vs. 60.7% of 163, P ≤ .001). Moreover, the results for the DPA group were close to those of the natural airway group (22.2% of 62 vs. 24.8% of 233, P = .66) Results were similar for a sub-set of the above groups who required deep sedation or deep extubation. CLJT maneuvers were common in this ambulatory surgery setting. The new DPA device was associated with a reduced need for such manual maneuvers when compared with similar patients who received OPA or NPA devices and is comparable with the rate for natural airways.

Existential suffering is among the main symptoms refractory to treatment in people at the end of life. There is evidence in the literature on the use of palliative sedation, the controlled administration of sedative medication with the purpose of inducing a state of reduced consciousness or unconsciousness to relieve unbearable suffering experienced by people with terminal illnesses, to control existential suffering. This article presents the protocol for an integrative review which aims to analyze the evidence available in the literature on the use of palliative sedation to manage existential suffering in people with serious end-of-life illnesses. This is an integrative review protocol based on the steps described by Whittemore and Knalf, and reported in line with the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P). A comprehensive search strategy including carefully selected terms corresponding to the domains of interest (palliative sedation and existential suffering) will be used to search for the relevant literature in the PubMed, Scopus, Web of Science, CINAHL, Cochrane Library, and EMBASE databases. The Endnote and Rayyan softwares will be used for data management. This integrative review aims to identify existing gaps and contribute to the presentation of information that may contribute to settling the controversy regarding the use of palliative sedation to manage refractory existential suffering at the end of life.

Background: General anesthesia is preferred when prolonged and multiple dental procedures are required in the pediatric population. In children for whom neuromuscular blockers (NMBs) are contraindicated, dental treatments can be performed under deep sedation, but there is an increased risk of respiratory complications such as hypoxia and foreign body aspiration. Case Report: In this case report, due to a rocuronium allergy detected during the preoperative evaluation process, the application of nasal positive pressure ventilation support allowing prolonged deep sedation with complete immobilization was presented. Conclusion: Prolonged deep sedation using a nasal continuous positive airway pressure (CPAP) mask can be used as an alternative to general anesthesia during dental procedures, especially in patients with contraindications to NMBs. This approach can reduce the risk of hypoxia and hypercarbia with ventilatory support while providing total immobility with deep sedation. [ABSTRACT FROM AUTHOR]

Abstract Purpose Hypoxia is one of the most frequent adverse events under deep sedation in the semiprone position. We hypothesized that supraglottic jet oxygenation and ventilation (SJOV) via Wei nasal jet tube (WNJ) can reduce the incidence of hypoxia in patients under deep sedation during endoscopic retrograde cholangiopancreatography (ERCP). Methods A total of 171 patients were divided into three groups: N group, supplementary oxygen via a nasopharyngeal airway (4–6 L/min); W group, supplementary oxygen via WNJ (4–6 L/min); WS group, SJOV via WNJ. The primary outcome was the incidence of adverse events, including sedation-related adverse events [SRAEs, hypoxemia (SpO2 = 75–89% lasted less than 60 s); severe hypoxemia (SpO2

Background: Although gastrointestinal endoscopy with sedation is increasingly performed in older patients, the optimal level of sedation remains open to debate. In this study, our objective was to compare the effects of moderate sedation (MS) and deep sedation (DS) on recovery following outpatient gastroscopy in elderly patients. Methods: In this randomized, partially blinded, controlled trial, we randomly divided 270 patients older than 60 years who were scheduled for elective outpatient gastroscopy into the MS or DS group based on the Modified Observer's Assessment of Alertness/Sedation (MOAA/S) scale. The primary outcome was the duration of stay in the post-anesthesia care unit (PACU). Secondary outcomes included the duration of the total hospital stay, frequency of retching, bucking, and body movements during the examination, endoscopist and patient satisfaction, and sedation-associated adverse events during the procedure. Results: A total of 264 patients completed the study, of whom 131 received MS and 133 received DS. MS was associated with a shorter PACU stay [16.15 ± 9.01 min vs. 20.02 ± 11.13 min, P < 0.01] and total hospital stay [27.32 ± 9.86 min vs. 30.82 ± 12.37 min, P < 0.05], lesser hypoxemia [2.3% (3/131) vs. 12.8% (17/133), P < 0.01], use of fewer vasoactive drugs (P < 0.001), and more retching (P < 0.001). There was no difference in the incidence of bucking and body movements or endoscopist and patient satisfaction between the two groups. Conclusion: Compared to deep sedation, moderate sedation may be a preferable choice for American Society of Anesthesiologists (ASA) Grade I–III elderly patients undergoing outpatient gastroscopies, as demonstrated by shorter PACU stays and total hospital stays, lower sedation-associated adverse events, and similar levels of endoscopist and patient satisfaction.

Background: The European Association for Palliative Care (EAPC) acknowledges palliative sedation as an important, broadly accepted intervention for patients with life-limiting disease experiencing refractory symptoms. The EAPC therefore developed 2009 a framework on palliative sedation. A revision was needed due to new evidence from literature, ongoing debate and criticism of methodology, terminology and applicability. Aim: To provide evidence- and consensus-based guidance on palliative sedation for healthcare professionals involved in end-of-life care, for medical associations and health policy decision-makers. Design: Revision between June 2020 and September 2022 of the 2009 framework using a literature update and a Delphi procedure. Setting: European. Participants: International experts on palliative sedation (identified through literature search and nomination by national palliative care associations) and a European patient organisation. Results: A framework with 42 statements for which high or very high level of consensus was reached. Terminology is defined more precisely with the terms suffering used to encompass distressing physical and psychological symptoms as well as existential suffering and refractory to describe the untreatable (healthcare professionals) and intolerable (patient) nature of the suffering. The principle of proportionality is introduced in the definition of palliative sedation. No specific period of remaining life expectancy is defined, based on the principles of refractoriness of suffering, proportionality and independent decision-making for hydration. Patient autonomy is emphasised. A stepwise pharmacological approach and a guidance on hydration decision-making are provided. Conclusions: This is the first framework on palliative sedation using a strict consensus methodology. It should serve as comprehensive and soundly developed information for healthcare professionals.

Background: Although brimonidine is currently used in the clinical treatment of glaucoma and rosacea, research of the deep sedative effect on animals after systemic administration is reported firstly and has shown promising results. Methods: The median effective dose (ED50), the median lethal dose (LD50), and the therapeutic index of brimonidine for deep sedation and formalin stimulation assay were determined by various animal experiments. The effect of synergistic anesthesia in rabbits with brimonidine and chloral hydrate was preliminarily evaluated. Results: The ED50 of brimonidine for highly effective sedation by intraperitoneal injection in rats was calculated to be 2.05 mg kg−1 with a 95% confidence interval (CI) of 1.87 to 2.25 mg kg−1. The ED50 of brimonidine for deep sedation by intravenous and intrarectal injection in rabbits was calculated to be 0.087 mg kg−1 with a 95% CI of 0.084 to 0.091 mg kg−1 and 1.65 mg kg−1 with a 95% CI of 1.43 to 1.91 mg kg−1, respectively. The LD50 of intraperitoneal brimonidine injection in rats was calculated to be 468 mg kg−1 with a 95% CI of 441 to 497 mg kg−1 and a therapeutic index of 228. Brimonidine has a certain analgesic and heart rate lowering effects. Conclusion: The results confirmed that brimonidine has deep sedation and analgesic effects after systemic administration and has high safety. It can be used in combination with other types of sedative drugs to achieve better effects. [ABSTRACT FROM AUTHOR]

Purpose: Hypoxia is one of the most frequent adverse events under deep sedation in the semiprone position. We hypothesized that supraglottic jet oxygenation and ventilation (SJOV) via Wei nasal jet tube (WNJ) can reduce the incidence of hypoxia in patients under deep sedation during endoscopic retrograde cholangiopancreatography (ERCP). Methods: A total of 171 patients were divided into three groups: N group, supplementary oxygen via a nasopharyngeal airway (4–6 L/min); W group, supplementary oxygen via WNJ (4–6 L/min); WS group, SJOV via WNJ. The primary outcome was the incidence of adverse events, including sedation-related adverse events [SRAEs, hypoxemia (SpO2 = 75–89% lasted less than 60 s); severe hypoxemia (SpO2 < 75% at any time or SpO2 < 90% lasted more than 60 s] and subclinical respiratory depression (SpO2 = 90–95%). Other intraoperative and post-operative adverse events were also recorded as secondary outcomes. Results: Compared with the N group, the incidence of hypoxemia and subclinical respiratory depression in the WS group was significantly lower (21% vs. 4%, P = 0.005; 27% vs. 6%, P = 0.002). Compared with Group W, the incidence of hypoxemia and subclinical respiratory depression in Group WS was also significantly less frequent (20% vs. 4%, P = 0.009; 21% vs. 6%, P = 0.014). No severe hypoxia occurred in the group WS, while four and one instances were observed in the group N and group W respectively. There were no significant differences in other adverse events among the three groups. Conclusion: SJOV can effectively improve oxygenation during ERCP in deeply sedated semiprone patients.

Background and Objectives: Special Needs Patients (SNPs) and young non-collaborative children are more predisposed to develop oral pathologies due to poor collaboration and scarce access to dental treatment. The aim of this retrospective study was to analyze a sample of SNPs who received dental treatments either under general anesthesia (GA) or deep sedation (DS) over a period of 6 years. The number and type of procedure were analyzed. Materials and Methods: In total, 131 patients were included and mostly (>90%) treated under GA. Patients were either uncooperative and phobic (Group 1) or affected by mental, behavioral, and neurological disorders (Group 2), diseases of the nervous system (Group 3), or developmental anomalies (Group 4). Results: Patients in Group 2 required more invasive dental treatments than those in the other groups. Therapies were mainly preventive and restorative, except in Groups 3 and 4, where extractions were more frequent. The type of dental treatment significantly varied according to age and systemic condition. Only 5.3% of the patients needed a second intervention, despite only 17.6% of patients respecting the scheduled follow-up. Conclusions: Treatment under GA is effective, but the poor adherence to follow-ups and the risk of reintervention should be contrasted by improving the perception by parents/guardians of the importance of oral hygiene and periodic visits.

Introduction: Severe traumatic brain injury affects ∼4500 per year across the UK. Most patients undergo a period of sedation to prevent secondary brain injury, however the optimal sedation target is unclear. This study aimed to assess the relationship between the electroencephalogram (EEG)-based Bispectral Index™ (BIS™) value and the clinical sedation score, along with other clinical outcomes. Methods: Patients with severe traumatic brain injury in four UK ICUs were recruited to have blinded BIS data collected for a 24-h period while sedated on the ICU. Drug, physiological, and outcome data were recorded from the ICU record. Sedation management was at the discretion of the ICU clinical team. Results: Twenty-six participants were recruited to the study. The mean BIS was 38 (inter-quartile range 29–44) and there was poor correlation between BIS and sedation score as a group (correlation coefficient 0.17, 95% confidence interval 0.08–0.26), however the spread in BIS values increased with decreasing sedation score. There was no statistically significant relationship between BIS and intracranial pressure, vasopressor use, osmotherapy use, or need for an additional sedative. Conclusion: This study supports previous work showing that BIS decreases with decreasing sedation score. However, the variation in BIS values increased with deeper levels of clinical sedation. Patients may not be benefiting from the full potential of sedation in traumatic brain injury and further studies of sedation titrated to an EEG-based parameter are needed. Clinical trial registration: NCT03575169.

Background: Our objective was to compare the safety and efficacy of Target-Controlled Infusion (TCI) versus intermittent bolus of propofol for colonoscopy sedation. Methods: We conducted a randomized (1:1), single-blind, parallel-group superiority trial with fifty ASA I or II patients, both sexes, aged 18 to 65 years, Body Mass Index ≤ 30 kg.m−2, undergoing colonoscopy, allocated to receive propofol by TCI (effect-site, 2 μg.mL−1 plus 0.5 μg.mL−1 until unconsciousness and as necessary for agitation) or intermittent bolus (1 mg.kg−1 plus 0.5 mg.kg−1 every 5 minutes or as above). The primary safety outcome was the need for airway maneuvers and the primary efficacy outcome was the need for interventions to adjust the level of sedation. Secondary outcomes included incidence of agitation, propofol dose, and time to recovery. Results: The median (IQR) number of airway maneuvers and interventions needed to adjust sedation was 0 (0‒0) vs. 0 (0‒0) (p = 0.239) and 1 (0‒1) vs. 3 (1‒4) (p < 0.001) in the TCI and control groups, respectively. Agitation was more common in the intermittent bolus group ‒ 2 (0‒2) vs. 1 (0‒1), p < 0.001. The mean ± SD time to recovery was 4.9 ± 1.4 minutes in the TCI group vs. 2.3 ± 1.6 minutes in the control group (p < 0.001). The total propofol dose was higher in the TCI group (234 ± 46 µg.kg−1.min−1 vs. 195 ± 44 µg.kg−1.min−1 (p = 0.040)). Conclusions: During colonoscopy, TCI is as safe as intermittent bolus of propofol while reducing the incidence of agitation and the need for dose adjustments. However, intermittent bolus administration was associated with lower total propofol dose and earlier recovery.

Background Endobronchial ultrasound (EBUS) is widely used to diagnose lung cancer. Monitored anesthesia care (MAC) can enhance patient comfort and procedural conditions during EBUS. EBUS under MAC is usually safe but can lead to various complications. Case A 34-year-old male who had increased sputum for two months showed an enlarged paratracheal lymph node and planned for lymph node biopsy by EBUS. During EBUS under MAC, an unexpected oxygen saturation decline required intervention. After intubation, copious frothy fluid was suctioned from the bronchi, and oxygenation was recovered. A narrowed trachea and the EBUS bronchoscope might have resulted in upper airway obstruction, and suction performed under these conditions might have caused pulmonary edema. The patient received non-invasive ventilation and high-flow nasal cannula and recovered without complications. Conclusions When there is an expected risk of upper airway obstruction during EBUS, careful preoperative evaluation and preparation are essential to prevent negative pressure pulmonary edema.

Abstract Background Continuous deep sedation (CDS) can be used for patients at the end of life who suffer intolerably from severe symptoms that cannot be relieved otherwise. In the Netherlands, the use of CDS is guided by an national guideline since 2005. The percentage of patients for whom CDS is used increased from 8% of all patients who died in 2005 to 18% in 2015. The aim of this study is to explore potential causes of the rise in the use of CDS in the Netherlands according to health care providers who have been participating in this practice. Methods Semi-structured interviews were conducted and thematically analysed. Participants were Dutch health care providers (HCPs), working at patients’ homes, hospices, elderly care facilities and in hospitals and experienced in providing CDS, who were recruited via purposeful sampling. Results 41 Health care providers participated in an interview. For these HCPs the reason to start CDS is often a combination of symptoms resulting in a refractory state. HCPs indicated that symptoms of non-physical origin are increasingly important in the decision to start CDS. Most HCPs felt that suffering at the end of life is less tolerated by patients, their relatives, and sometimes by HCPs; they report more requests to relieve suffering by using CDS. Some HCPs in our study have experienced increasing pressure to perform CDS. Some HCPs stated that they more often used intermittent sedation, sometimes resulting in CDS. Conclusions This study provides insight into how participating HCPs perceive that their practice of CDS changed over time. The combination of a broader interpretation of refractory suffering by HCPs and a decreased tolerance of suffering at the end of life by patients, their relatives and HCPs, may have led to a lower threshold to start CDS. Trial registration The Research Ethics Committee of University Medical Center Utrecht assessed that the study was exempt from ethical review according to Dutch law (Protocol number 19–435/C).

Introduction: Percutaneous ultrasound-guided radiofrequency ablation (RFA) is a well-studied treatment option for locally non-advanced hepatocellular carcinoma (HCC) and colorectal liver metastases (CRLMs). Sedation is of crucial interest as it enables safe and pain-free procedures. Whether the type of sedation has an impact on procedural outcome is still not well investigated. Methods: We retrospectively collected data on patients undergoing liver RFA for various oncological conditions. Procedures were conducted in a non-operating room anesthesia (NORA) setting. Procedural-related complications and short-term oncological outcomes were analyzed. Results: Thirty-five patients (mean age 71.5 y, 80% male) were treated for HCC (26), CRLM (6) and gastric cancer metastases (3). Mean lesion size was 21 mm (SD ± 10.1 mm), and the most common tumor localization was the right hepatic lobe. RFA was performed in a step-up sedation approach, with subcutaneous lidocaine injection prior to needle placement and subsequent deep sedation during ablation. No anesthesia-related early or late complications occurred. One patient presented with pleural effusion due to a large ablation zone and was treated conservatively. Local tumor-free survival after 1 and 6 months was 100% in all cases where a curative RFA approach was intended. Conclusions: NORA for liver RFA comes with high patient acceptance and tolerance, and optimal postoperative outcomes and oncologic results.

General anesthesia is critical for various procedures and surgeries. Despite the widespread use of anesthetics, their precise mechanisms remain poorly understood. Anesthetics inevitably act on the brain, primarily through the modulation of target receptors. Even if the action is specific to an individual neuron, however, long-range effects can occur due to the tremendous interconnectedness of neuronal activity. The strength of this connectivity can be understood using mathematical models that allow for the study of neuronal connectivity dynamics. These models also allow researchers to develop hypotheses on the candidate mechanisms of action of different types of anesthesia. This review highlights the theoretical background associated with the study of the mechanisms of action of anesthetics. We propose a candidate framework that describes how anesthetics act on the brain and consciousness in general.

- Abstract
To study the anesthesia effect and safety analysis of endoscopic diagnosis and treatment of esophageal and gastric varices under conscious sedation and deep sedation. 94 patients with esophageal and gastric varices admitted to our hospital from May 2020 to September 2021 were selected and randomly divided into a control group and an observation group using a random number table method, with 47 patients in each group. The control group received conscious sedation(midazolam+fentanyl), while the observation group received deep sedation with propofol added to the control group. Observe the changes in basic vital signs of patients during surgical treatment, as well as the anesthesia effect and safety after surgical treatment in the control group and observation group. Compare the total effective rate of two groups of patients after treatment. The total effective rate of the observation group was significantly higher than that of the control group, and the difference was statistically significant (P<0.05). The discharge time, anesthesia compliance time, and postoperative extubation time of the observation group were significantly shorter than those of the control group, with statistical significance (P<0.05). There was no significant difference in HR between the experimental groups at different time points (P>0.05). At T2, T3, and T4, the MAP and HR of the experimental group patients were significantly reduced compared to the control group (P<0.05). There was no statistically significant difference in Ramsay scores during surgery and postoperative satisfaction between the two groups of patients. The incidence of adverse reactions in the control group and the observation group was 12.75% and 8.49%, respectively, with no statistically significant difference between the two groups(P>0.05). Deep sedation has a significant and safe therapeutic effect on endoscopic diagnosis and treatment of esophageal and gastric varicose veins, with a short course of treatment, fast response, fast recovery, high patient acceptance, and improved treatment success rate. It is worth promoting. [ABSTRACT FROM AUTHOR]

Background: Endoscopic submucosal dissection (ESD) of rectal tumors involving the dentate line (RT-DL) is challenging because of the anatomical features of the anal canal. This study aimed to identify optimal techniques and sedation and to determine the clinical outcomes of ESD for RT-DL. Methods: We retrospectively collected medical records and endoscopic results of patients who underwent ESD for rectal tumors between January 2012 and April 2021. Patients were divided into RT-DL and rectal tumors not involving the dentate line (RT-NDL) groups, as per involvement of the dentate line. The treatment results and clinical outcomes of the two groups were evaluated and analyzed. Additionally, subgroup analysis was performed in the RT-DL group for the sedation method involved. Results: In total, 225 patients were enrolled and 22 were assigned to the RT-DL group. The complete resection rate (90.9% vs. 95.6%, P =0.336), delayed bleeding (13.6% vs. 5.9%, P =0.084), perforation (0% vs. 3.9%, P = 0.343), hospital stays (4.55 vs. 4.48 days, P = 0.869), and recurrence (0% vs. 0.5%) showed no significant group differences. However, in RT-DL group, the procedure time (78.32 vs. 51.10 min, P = 0.002) was longer and there was more perianal pain (22.7% vs. 0%, P = 0.001). The subgroup analysis revealed that deep sedation using propofol reduced perianal pain during the procedure (0/14 vs. 5/8, P = 0.002). Conclusions: ESD of RT-DL is a safe and effective treatment despite the challenges of requiring a high level of technique and longer procedure time. In particular, ESD under deep sedation should be considered in patients with RT-DL to control perianal pain. [ABSTRACT FROM AUTHOR]

Purpose: The purposes of this retrospective study were to investigate the incidence of cardiac and respiratory complications in pediatric patients undergoing dental procedures with deep propofol sedation and examine the factors that may lead to the development of these complications. Methods: This study was carried out using the records of 421 pediatric patients who received dental treatment with deep sedation. Previously recorded cardiac/respiratory complications were noted. In addition, factors such as age, gender, body mass index (BMI), propofol induction/infusion/total dose, operation duration, and the presence of comorbidities, which were investigated whether they affect these complications, were also noted. Data were analyzed with Mann-Whitney U, chi-square, and Fisher exact tests using univariable and multivariable logistic regression analyses. A level of five percent was considered to indicate statistical significance. Results: There were no significant differences between the cases with and without complications in terms of gender, age, BMI, total propofol dose, and operation time (P=0.887, P=0.827, P=0.213, P=0.581, and P=0.081, respectively). According to the multivariable logistic regression analysis, trisomy 21, heart disease, and asthma were found to be significant risk factors for the development of these complications (odds ratios equal 9.776, 3.257, and 14.646, respectively, 95 percent confidence interval; 3.807-25.100, 1.095-9.690, 4.110-52.188, respectively). Conclusion: Considering the limitations of this study, to minimize cardiorespiratory complications it is recommended that patients with comorbidities should not be managed with deep sedation and an open airway.
