SEDATION ASSESSMENT IN MECHANICAL VENTILATED PATIENTS: THE LEVEL OF KNOWLEDGE ASSESSMENT AMONG CRITICAL NURSES IN A PUBLIC TERTIARY CARE HOSPITAL LAHORE

By appropriately evaluating and controlling sedation in patients on mechanical ventilation, nursing problems can be prevented. However, critical care nurses in public tertiary care hospitals with limited training and resources continue to lack certain expertise. Critical care nurses need to assess and manage sedation. Patients are at significant risk from both over and insufficient sedation. Critical care nurses must possess adequate expertise in sedation assessment and management. Objective: The study's objective is to evaluate critical care nurses' knowledge in sedation management for patients on mechanical ventilation at Pakistan's public tertiary care hospitals. Method: A cross-sectional study with a descriptive design was carried out at the public tertiary care hospital in Lahore. Convenience sampling techniques were used to recruit study participants from the critical care unit. Knowledge levels were divided into three categories: poor, fair and good. Data was collected through questionnaires, which were evaluated using descriptive statistical analysis. Results: The result showed that 36% had fair knowledge, just 16% of the nurses had a strong understanding of sedation management, and 48% of the nurses had low knowledge. Conclusion: The study highlighted a significant lack of sedation management knowledge among critical care nurses in public tertiary care hospitals. Addressing these gaps through targeted training and standardized sedation protocols is essential for improving patient safety in critical settings.

Evaluation of gabapentin administration on neurologic examination in 2 different age groups of healthy cats.

Gabapentin is often administered PO for preappointment or in-hospital anxiolysis in cats. A previous study reported mild changes on the neurologic examination after administration. Investigate the effects of gabapentin on anxiety, sedation, compliance, and neurologic examination in 2 age groups of cats. Thirty-one young cats and 12 geriatric cats perceived by their owners to be healthy and neurologically normal. Prospective double-blinded clinical crossover study. Assessment of baseline sedation and anxiety was performed before initial neurologic examinations and after gabapentin administration (100 mg/cat). Assessments were repeated 90 to 120 minutes after administration. Ease of handling pregabapentin and postgabapentin was assessed in the younger cats. All examinations were performed by a board-certified veterinary neurologist and scoring of examinations was performed by a different, masked board-certified neurologist. Sixteen cats (50%) in the younger cohort and 6 cats (50%) in the geriatric cohort exhibited an increase in their overall neurologic examination score postgabapentin administration, mainly through new or progressive postural reaction deficits and gait changes. Anxiety and sedation scores were significantly changed in the geriatric population (P < .01, P = .004, respectively); however, only sedation scores were significantly increased in the younger cats after gabapentin administration (P = .004). All study participants showed mild neurologic changes after gabapentin administration, most markedly noted in the geriatric population. Dose reduction of gabapentin for preappointment anxiolysis and neurologic examination in geriatric patients should be considered.

Efficacy and Safety of Ciprofol Versus Propofol as Anesthetic for Patients Undergoing Painless Colonoscopy.

Ciprofol is a novel propofol analogue with a characteristic of hemodynamic stability. At present, there is a lack of research comparing the hemodynamic stability of ciprofol and propofol during painless colonoscopy. In this study, we aim to test the hypothesis that ciprofol is superior to propofol in terms of hemodynamic stability for sedation anesthesia in patients undergoing colonoscopy. A total of 222 patients were randomized into two groups. Patients in group P (n=112) and group C (n=110) received propofol and ciprofol sedation, respectively. Noninvasive blood pressure were monitored starting from induction (T0) to the end of the procedure, at 2-min intervals (T1 to T10). Heart rate variability (HRV), pain injection, Modified Observer's Assessment of Alertness and Sedation(MOAA/S) score, body movement, doses of norepinephrine, modified Aldrete score, drug-related adverse reactions, and patient satisfaction and endoscopist satisfaction were recorded. In group C, fewer patients experienced a decrease in blood pressure with a higher HRV after induction sedation, the incidence of pain injection was reduced, the amount of norepinephrine dose was decreased, patient satisfaction was increased compared with group P (all P<0.05). There were no significant differences in induction time, modified Aldrete score, alertness time, drug-related adverse reactions, and endoscopist satisfaction. Our study indicated intravenous induction with ciprofol was superior, with regard to hemodynamic stability and reduced injection pain, than induction with propofol for anesthesia in patients undergoing painless colonoscopy.

Pediatric Sedation Assessment and Management System (PSAMS) for Pediatric Sedation in China: Development and Implementation Report.

Recently, the growing demand for pediatric sedation services outside the operating room has imposed a heavy burden on pediatric centers in China. There is an urgent need to develop a novel system for improved sedation services. This study aimed to develop and implement a computerized system, the Pediatric Sedation Assessment and Management System (PSAMS), to streamline pediatric sedation services at a major children's hospital in Southwest China. PSAMS was designed to reflect the actual workflow of pediatric sedation. It consists of 3 main components: server-hosted software; client applications on tablets and computers; and specialized devices like gun-type scanners, desktop label printers, and pulse oximeters. With the participation of a multidisciplinary team, PSAMS was developed and refined during its application in the sedation process. This study analyzed data from the first 2 years after the system's deployment. From January 2020 to December 2021, a total of 127,325 sedations were performed on 85,281 patients using the PSAMS database. Besides basic variables imported from Hospital Information Systems (HIS), the PSAMS database currently contains 33 additional variables that capture comprehensive information from presedation assessment to postprocedural recovery. The recorded data from PSAMS indicates a one-time sedation success rate of 97.1% (50,752/52,282) in 2020 and 97.5% (73,184/75,043) in 2021. The observed adverse events rate was 3.5% (95% CI 3.4%-3.7%) in 2020 and 2.8% (95% CI 2.7%-2.9%) in 2021. PSAMS streamlined the entire sedation workflow, reduced the burden of data collection, and laid a foundation for future cooperation of multiple pediatric health care centers.

Sedation Experiences of Pediatric Intensive Care Nurses: Exploring PICU Nurse Perspectives on Sedative Management and Communication.

Objective: This study's purpose is to better understand pediatric intensive care nursing perspectives on sedative management as a precursor to improving aspects of sedation assessment, titration, and communication. Methods/Design: We queried nurses in the pediatric intensive care unit at a 40+ bed quaternary care using an electronic survey about their experiences with sedation management. Data was collected using REDCap and statistical analyses were performed to assess for differences between experience levels in areas. Results: Seventy nurses responded with 42% response rate. More than 95% were comfortable calculating sedation and delirium scores. Those with less than 5 years' experience were significantly more likely to consider sedation scores helpful (P = .04) and also significant more likely to agree that delirium scores are used effectively (P = .01). Eighty-eight percent of respondents were comfortable raising concerns about sedation to the multidisciplinary team, but those with less than 5 years' experience were significantly less likely to express concerns to attending (P = .001). Conclusion: Newer nurses are more inclined to support use of standardized scoring systems for sedation and delirium, but less comfortable approaching attending clinicians with their concerns. Intensive care teams should pay careful attention to team dynamics, particularly as they apply to sedative management and work to improve communication, collaboration, and educational interventions to improve patient care. Further work understanding nursing perspectives and further attempts to improve interprofessional communication seems a wise investment and could obviate barriers that may exist.

Bispectral Index monitoring of palliative sedation for home withdrawal of tracheostomy ventilation: A case report.

Tracheostomy ventilation in motor neurone disease is an uncommon life-sustaining treatment. Best practice is having a plan for ventilation withdrawal, but the literature to guide practice is limited. Case reports have documented standard doses of opioids and benzodiazepines used for sedation in such cases. A 49-year-old man was diagnosed with motor neurone disease in 2016. He commenced tracheostomy ventilation in 2018. In 2022 and 2023, planning was undertaken, at the patient's request, for withdrawal of tracheostomy ventilation at home, when he was no longer able to communicate with technology. Planning included Bispectral Index monitoring prior to cessation of ventilation, ensuring this only occurred when deep sedation was achieved. After ventilation withdrawal in 2023, a retrospective review of medications given and his level of sedation on monitoring was undertaken, with family consent. Ventilation withdrawal was initiated after deep sedation was achieved, 6 h after commencing subcutaneous infusions of morphine, midazolam, clonazepam and phenobarbital. Doses required to achieve acceptable sedation exceeded literature reports. Achieving deep sedation was a longer than expected process. More research using an objective measure of sedation is required, as clinical assessment of sedation in this context is compromised.

Comparing Patient Comfort During Bronchoscopy Under Conscious Sedation and Monitored Anesthesia Care: A Prospective, Observational, Controlled Study.

Flexible bronchoscopy (FB) often involves sedation, with the choice left to the bronchoscopist's discretion. Prior research on sedation in gastroscopic endoscopies yields conflicting information regarding the preferred method for FB. This study compares patient comfort levels during bronchoscopy with mindful sedation using fentanyl, nalbuphine, and midazolamversus monitored anesthesia care (MAC) using propofol, midazolam, and ketamine. This prospective observational study assessed 83 patients undergoing bronchoscopy under either conscious sedation (CS) (n=40) or MAC (n=43). Patient comfort, sedation levels, emotional state, recovery time, safety, and the impact of smoking history and comorbidities were evaluated. Data collection included direct patient questioning and observation using the Modified Observed Assessment of Alertness and Sedation (MOAA/S) form. Comfort levels were similar between groups, with mean scores of 3.6±0.89 for CS and 3.3±0.54 for MAC. MAC induced deeper sedation (mean scores: 4.37±0.66 vs. 3.8±0.98). Recovery time and complications were comparable. Emotional states and medical history did not significantly differ between groups. CS is not inferior to MAC for bronchoscopy, providing comparable comfort and safety with less intense sedation and lower cost. These findings support the use of CS for bronchoscopy procedures, offering a cost-effective alternative without compromising patient comfort or safety.

Evaluation of the effects of pregabalin and dexamethasone coadministration on preemptive multimodal analgesia and anxiety in third molar surgeries: a triple-blind randomized clinical trial.

To evaluate the efficacy of pregabalin and dexamethasone coadministration in preemptive analgesia and anxiety control in lower third molar surgery. A triple-blind, split-mouth clinical trial conducted with patients divided into two groups: control group, receiving placebo and dexamethasone, and test group, receiving pregabalin and dexamethasone preoperatively. The evaluated variables were pain, measured by the Visual Analog Scale (VAS), anxiety assessed through the State-Trait Anxiety Inventory (STAI) questionnaires, hemodynamic parameters [Blood Pressure (BP), Heart Rate (HR), Oxygen Saturation (SpO2)], and sedation assessed by the Ramsay scale. A total of 31 patients were included. The test group exhibited a significant reduction in pain at 2,4,6,8,12,16,24, and 48h after surgery and in the consumption of rescue analgesics. Anxiety, evaluated by STAI and VAS, showed a significant decrease in the test group (p < 0.001). Additionally, there was a significant decrease in BP at most of the assessed time points (p < 0.05) and a significant reduction in HR at two different time intervals (p = 0.003 and p = 0.009), indicating a positive effect in the test group. There was no significant difference in SpO2 between the groups. Sedation assessment revealed a significant difference at all time points favoring the test group (p < 0.05). There were no significant postoperative adverse effects. Pregabalin coadministered with dexamethasone demonstrated significant efficacy in controlling postoperative pain and anxiety, as well as a sedative effect. The coadministration of pregabalin with dexamethasone may presents potential advantages in both pain modulation and psychological well-being of individuals undergoing third molar surgeries.

Ketamine for Primary Analgosedation in Critically Ill Surgery and Trauma Patients Requiring Mechanical Ventilation.

Evaluate effectiveness and safety outcomes associated with the use of ketamine for primary analgosedation in the surgical/trauma ICU setting. Retrospective cohort study. Academic medical center in Minnesota. Patients admitted to the surgical ICU between 2015 and 2019 requiring mechanical ventilation and meeting one of three definitions for ketamine primary analgosedation were included: 1) no concomitant opioid infusion, 2) ketamine monotherapy for greater than or equal to 6 hours with subsequent opioid infusion, or 3) ketamine initiated concomitantly or within 4 hours of opioid and total opioid duration less than 4 hours. None. Use of ketamine, analgesics, and sedatives were evaluated. Pain, sedation, and delirium assessments immediately before and during ketamine infusion were collected and compared with reported goals. Concomitant analgesics, sedatives, and psychotropics were recorded. Reported failures due to ineffectiveness and toxicity were collected. Of 164 included patients, 88% never received a concomitant opioid infusion (primary analgosedation definition 1), 12% met alternative criteria for primary analgosedation (definitions 2 and 3). A majority, 68%, were surgical admissions and mean Acute Physiology and Chronic Health Evaluation III score was 90 (± 30). Median mechanical ventilation duration was 2.5 days (1.1-4.5) and ICU length of stay of 4.9 days (3-8). The median ketamine infusion dose and duration were 0.18 mg/kg/hr (0.1-0.3) and 30 hours (15.1-51.8). Concomitant infusions of propofol and dexmedetomidine were administered in 49% and 29% of patients, respectively. During ketamine infusion, the median percent of total pain scores at goal was 62% (33-96%), while 64% (37-91%) of Richmond Agitation Sedation Scale scores were at goal, and 47% of patients were Confusion Assessment Method-ICU positive during the ketamine infusion. Hallucinations were documented in 14% of patients and ketamine failure occurred in 11% of patients. Ketamine may be an effective primary analgosedation option in intubated surgical ICU patients, but prospective randomized studies are needed to evaluate this strategy.

Improving Outcomes in Mechanically Ventilated Adult ICU Patients Following Implementation of the ICU Liberation (ABCDEF) Bundle Across a Large Healthcare System.

To measure how the ICU Liberation Bundle (aka ABCDEF Bundle or the Bundle) affected clinical outcomes in mechanically ventilated (MV) adult ICU patients, as well as bundle sustainability and spread across a healthcare system. We conducted a multicenter, prospective, cohort observational study to measure bundle performance versus patient outcomes and sustainability in 11 adult ICUs at six community hospitals. We then prospectively measured bundle spread and performance across the other 28 hospitals of the healthcare system. A large community-based healthcare system. In 11 study ICUs, we enrolled 1,914 MV patients (baseline n = 925, bundle performance/outcomes n = 989), 3,019 non-MV patients (baseline n = 1,323, bundle performance/outcomes n = 1,696), and 2,332 MV patients (bundle sustainability). We enrolled 9,717 MV ICU patients in the other 28 hospitals to assess bundle spread. We used evidence-based strategies to implement the bundle in all 34 hospitals. We compared outcomes for the 12-month baseline and bundle performance periods. Bundle implementation reduced ICU length of stay (LOS) by 0.5 days (p = 0.02), MV duration by 0.6 days (p = 0.01), and ICU LOS greater than or equal to 7 days by 18.1% (p < 0.01). Performance period bundle compliance was compared with the preceding 3-month baseline compliance period. Compliance with pain management and spontaneous awakening trial (SAT) and spontaneous breathing trial (SBT) remained high, and reintubation rates remained low. Sedation assessments increased (p < 0.01) and benzodiazepine sedation use decreased (p < 0.01). Delirium assessments increased (p = 0.02) and delirium prevalence decreased (p = 0.02). Patient mobilization and ICU family engagement did not significantly improve. Bundle element sustainability varied. SAT/SBT compliance dropped by nearly half, benzodiazepine use remained low, sedation and delirium monitoring and management remained high, and patient mobility and family engagement remained low. Bundle compliance in ICUs across the healthcare system exceeded that of study ICUs. The ICU Liberation Bundle improves outcomes in MV adult ICU patients. Evidence-based implementation strategies improve bundle performance, spread, and sustainability across large healthcare systems.

Propofol Versus Dexmedetomidine for Conscious Sedation During Vaginal Hysterectomy With Pre-emptive Local Anesthesia: A Prospective Cohort Study.

Hysterectomy is the most frequent gynecological surgery. Vaginal hysterectomy (VH) seems to be related to favorable perioperative outcomes compared to abdominal or laparoscopic approaches. As the population ages, anesthesia that is safer for the elderly, such as local anesthesia (LA) with conscious sedation, is gaining popularity and is related to favorable outcomes in patients' recovery compared to general or regional anesthesia. We aimed to evaluate the efficacy of dexmedetomidine versus propofol for women undergoing VH for uterine prolapse under LA and conscious sedation. A prospective study on 40 women with uterine prolapse stage ≥3 who had VH under LA with conscious sedation under either dexmedetomidine (n=20) or propofol (n=20) was performed. A standardized surgical approach with continuous hemodynamic monitoring and sedation assessment using the Ramsay Sedation Scale (RSS) was conducted. The primary endpoint of the study was to determine the percentage of patients receiving intraoperative fentanyl. Analysis of outcomes demonstrated a significant reduction in the proportion of patients requiring intraoperative rescue fentanyl (35% vs. 5%, respectively, p=0.04) and in postoperative pain scores, with more patients achieving an optimal RSS score of 3 in the dexmedetomidine group. Based on the findings of the present study, dexmedetomidine offered superior analgesia and patient comfort compared to propofol, suggesting a favorable anesthetic profile for VH under LA.

Sedation and Delirium Management in the Intensive Care Unit: A Comprehensive Review

In Intensive Care Units (ICUs), managing pain, sedation, and delirium is critical for patient comfort and outcomes. Historically, deep sedation was common, but advances in ventilator technology and shorteracting sedatives have led to a shift towards lighter sedation strategies. Delirium, often linked to oversedation, is associated with increased mortality and negative long-term outcomes, emphasizing the need for balanced approaches. Current guidelines recommend an "analgesia-first" approach, promoting lighter sedation to minimize ventilation duration and facilitate early mobilization. Preferred sedatives include propofol and dexmedetomidine, with benzodiazepines generally avoided due to their association with delirium. Research suggests that early light sedation in the ICU improves clinical outcomes, including reduced mortality, shorter ventilation, and ICU stays. However, the timing of initiating light sedation, sedation assessment tools, and the combination of sedative agents present challenges in practical implementation. Multimodal sedation approaches involving various agents at lower doses aim to enhance patient comfort while minimizing side effects. Delirium-prevention strategies, including nonpharmacological interventions, are also crucial. Frameworks like the ICU Liberation Bundle and the eCASH approach emphasize patient-centered care, early assessment and intervention, and family involvement to optimize outcomes. In conclusion, achieving optimal sedation outcomes in ICU patients requires a comprehensive strategy that combines analgesia-first principles, light sedation, multimodal approaches, and delirium prevention measures.

Sedation Research in Critically Ill Pediatric Patients: Proposals for Future Study Design From the Sedation Consortium on Endpoints and Procedures for Treatment, Education, and Research IV Workshop.

Sedation and analgesia for infants and children requiring mechanical ventilation in the PICU is uniquely challenging due to the wide spectrum of ages, developmental stages, and pathophysiological processes encountered. Studies evaluating the safety and efficacy of sedative and analgesic management in pediatric patients have used heterogeneous methodologies. The Sedation Consortium on Endpoints and Procedures for Treatment, Education, and Research (SCEPTER) IV hosted a series of multidisciplinary meetings to establish consensus statements for future clinical study design and implementation as a guide for investigators studying PICU sedation and analgesia. Twenty-five key elements framed as consensus statements were developed in five domains: study design, enrollment, protocol, outcomes and measurement instruments, and future directions. A virtual meeting was held on March 2-3, 2022, followed by an in-person meeting in Washington, DC, on June 15-16, 2022. Subsequent iterative online meetings were held to achieve consensus. Fifty-one multidisciplinary, international participants from academia, industry, the U.S. Food and Drug Administration, and family members of PICU patients attended the virtual and in-person meetings. Participants were invited based on their background and experience. None. Common themes throughout the SCEPTER IV consensus statements included using coordinated multidisciplinary and interprofessional teams to ensure culturally appropriate study design and diverse patient enrollment, obtaining input from PICU survivors and their families, engaging community members, and using developmentally appropriate and validated instruments for assessments of sedation, pain, iatrogenic withdrawal, and ICU delirium. These SCEPTER IV consensus statements are comprehensive and may assist investigators in the design, enrollment, implementation, and dissemination of studies involving sedation and analgesia of PICU patients requiring mechanical ventilation. Implementation may strengthen the rigor and reproducibility of research studies on PICU sedation and analgesia and facilitate the synthesis of evidence across studies to improve the safety and quality of care for PICU patients.

Analgosedation Management in the Intensive Care Unit: A Narrative Systematic Review

Background: Intensive care unit (ICU) patients' pain and sedation management is a significant nursing challenge. Sedatives and muscle relaxants administration has been long used for improving patients' comfort and tolerance to mechanical ventilation. This practice led to an increase in adverse ICU outcomes in terms of health status, hospitalization stay, infections, and mortality. The use of appropriate ICU pain and sedation assessment tools is limited. Methods: We conducted a narrative literature systematic review (from 2010 to 2022) whose primary aims were to analyze the analgosedation definition and identify ICU patients’ pain, agitation, and sedation assessment tools; secondary aims were to explore analgesia and sedation pharmacological and non-pharmacological treatments and nurses’ perceptions and attitudes regarding analgosedation issues. Results: We retrieved 45 eligible articles. Analgosedation foresees early pain management - using pharmacological and non-pharmacological approaches and then, if necessary, implementing adequate sedation. Recommended assessment tools are the Behavioral Pain Scale (BPS) and the Critical Care Observational Tool (CPOT) for pain assessment, the Richmond Agitation Sedation Scale (RASS), and the Sedation Agitation Scale (SAS) for sedation assessment. Guidelines and specific protocols recommend both pharmacological and non-pharmacological approaches. Health professionals report mainly barriers (lack of adherence to guidelines and protocols, workload, reduced awareness, and own perceptions) to analgosedation correct application. The implementation of ICU analgosedation strategies requires continuous health professionals’ commitment and collaboration and valid assessment tools use. Conclusion: ICU analgosedation management (pain control first, and then sedation if necessary) is limited due to health professionals' knowledge gaps, inappropriate use of assessment tools, guidelines, and specific protocols. Recommended assessment tools are the BPS and CPOT for pain assessment and the RASS and SAS for sedation assessment. Interventions to improve ICU analgosedation awareness and practice include training events, the use and consultation of literature guidelines, and the use of validated assessment tools.

Comparison of different weight-based scalars of remimazolam tosylate for anesthesia induction in obese patients: study protocol for a prospective, controlled trial

BackgroundThe physiologic and anthropometric characteristics changes associated with obesity may result in the alternation of pharmacologic management. Remimazolam tosylate is a new type of ultra-short-acting benzodiazepine with stable context-sensitive half-time (CSHT) and no lipid accumulation after long-time infusion. Although remimazolam tosylate has potential advantages for the induction and maintenance of anesthesia in obese patients, the appropriate induction dosing scalars among obese patients are unknown. Therefore, we aim to compare the different weight-based scalars for dosing remimazolam tosylate of anesthesia induction among obese patients.Methods/designThe study will be performed as a prospective, single-center, double-blind, controlled clinical trial. The study design is a comparison of remimazolam tosylate requirements based on total body weight (TBW) or lean body weight (LBW) to reach a Modified Observer’s Assessment of Alertness and Sedation (MOAA/S) score of 0 among obese subjects (BMI ≥ 35 kg/m2). Another twenty normal-weight subjects (18.5 kg/m2 ≤ BMI < 25 kg/m2) will be enrolled as a control group, whose induction dose is scaled based on TBW. The infusion rate of remimazolam tosylate during induction is 12 mg/kg/h in all groups.DiscussionResults of the present study will provide evidence of dose scalar of remimazolam tosylate to guide the clinical practice of anesthesia induction in obese patients.Trial registrationChinese Clinical Trial Registry ChiCTR220005664.

Bispectral Index Monitoring: Ability to Detect Deep Sedation during Endoscopy

Background: Clinical practice guidelines recommend monitoring the depth of anesthesia during endoscopic examination of the gastrointestinal tract using sedation scales, despite their subjective nature, while the use of the bispectral index, an objective measure, during sedation, remains controversial. The main objective of this study was to assess the ability of bispectral index monitoring to characterize the depth of anesthesia during endoscopy. Methods: We conducted a cross-sectional study to assess the performance of the bispectral index using data from a multicentre clinical trial with 180 patients undergoing scheduled colonoscopies. Sedation was monitored using the bispectral index and Ramsay Sedation Scale. Data on sedation were recorded at five-time points (t1 to t5) during the colonoscopy. Results: Bispectral values were significantly associated with Ramsay scores (rho, -0.73; p &lt; 0.0001). In regression analysis, each unit increase in bispectral value was associated with a reduction in the risk of a high Ramsay score (&gt; 3) at all points (OR 0.922; 95% CI: 0.865–0.979; p &lt; 0.0001 at t1). Receiver operating characteristic curve analysis found areas under the curve of 0.8272 for a bispectral index cut-off for deep sedation of 69.76 (sensitivity, 95.35%; negative predictive value, 97.53%) when reaching the colic flexure (t2) and 0.8399 for a cut-off of 69.29 (sensitivity, 96.15%; negative predictive value, 98.81%) at the end of the colonoscopy (t5). Conclusion: Bispectral index monitoring enables objective real-time reliable assessment of sedation. It enables easy continuous monitoring with a very good performance for detecting deep sedation and correlates with a clinical scale routinely used in endoscopic procedures.

An overview of patient knowledge of anesthesia procedures through informed consent in the Jatiwinangun Purwokerto Surgical Specialty Hospital's central surgical installation

Background: The submission of informed consent aims to obtain evidence of consent that can document legal and ethical liability. Anesthesia procedures include pre-anesthesia, intra-anesthesia and post-anesthesia. Pre-anesthesia is a pre-anesthesia and sedation assessment, informed consent for anesthesia and sedation, giving premedication drugs if necessary, and instructing fasting before surgery. Purpose: This study was to determine the level of patient knowledge about anesthesia procedures through informed consent at the Central Surgical Installation of Jatiwinangun Purwokerto Special Surgical Hospital. Methods: This study used a quantitative descriptive design with a cross sectional approach. The sampling technique used consecutive sampling of 108 respondents. The measuring instrument used was a questionnaire sheet. Analysis test using univariate test. Results: The analysis showed that the most dominant age of respondents was in the range of 36-45 years (23.4%), with the last education having a high school background (35%) and male (59.3%). Conclusion: An overview of the patient's knowledge level about anesthesia procedures through informed consent in the central surgical installation of Jatiwinangun Purwokerto Special Surgical Hospital, the majority have a sufficient level of knowledge.

Enhancing European Management of Analgesia, Sedation, and Delirium: A Multinational, Prospective, Interventional Before-After Trial

BackgroundThe objective of this study was to analyze the impact of a structured educational intervention on the implementation of guideline-recommended pain, agitation, and delirium (PAD) assessment.MethodsThis was a prospective, multinational, interventional before-after trial conducted at 12 intensive care units from 10 centers in Germany, Austria, Switzerland, and the UK. Intensive care units underwent a 6-week structured educational program, comprising online lectures, instructional videos, educational handouts, and bedside teaching. Patient-level PAD assessment data were collected in three 1-day point-prevalence assessments before (T1), 6 weeks after (T2), and 1 year after (T3) the educational program.ResultsA total of 430 patients were included. The rate of patients who received all three PAD assessments changed from 55% (107/195) at T1 to 53% (68/129) at T2, but increased to 73% (77/106) at T3 (p = 0.003). The delirium screening rate increased from 64% (124/195) at T1 to 65% (84/129) at T2 and 77% (82/106) at T3 (p = 0.041). The pain assessment rate increased from 87% (170/195) at T1 to 92% (119/129) at T2 and 98% (104/106) at T3 (p = 0.005). The rate of sedation assessment showed no signficiant change. The proportion of patients who received nonpharmacological delirium prevention measures increased from 58% (114/195) at T1 to 80% (103/129) at T2 and 91% (96/106) at T3 (p < 0.001). Multivariable regression revealed that at T3, patients were more likely to receive a delirium assessment (odds ratio [OR] 2.138, 95% confidence interval [CI] 1.206–3.790; p = 0.009), sedation assessment (OR 4.131, 95% CI 1.372–12.438; p = 0.012), or all three PAD assessments (OR 2.295, 95% CI 1.349–3.903; p = 0.002) compared with T1.ConclusionsIn routine care, many patients were not assessed for PAD. Assessment rates increased significantly 1 year after the intervention.Clinical trial registration ClinicalTrials.gov: NCT03553719.

Comparative analysis of the effect of electromyogram to bispectral index and 95% spectral edge frequency under remimazolam and propofol anesthesia: a prospective, randomized, controlled clinical trial.

Bispectral index (BIS), an index used to monitor the depth of anesthesia, can be interfered with by the electromyogram (EMG) signal. The 95% spectral edge frequency (SEF95) also can reflect the sedation depth. Remimazolam in monitored anesthesia care results in higher BIS values than propofol, though in the same sedation level assessed by Modified Observers Assessment of Alertness and Sedation (MOAA/S). Our study aims to illustrate whether EMG is involved in remimazolam causing higher BIS value than propofol preliminarily and to explore the correlations among BIS, EMG, and SEF95 under propofol and remimazolam anesthesia. Twenty-eight patients were randomly divided into propofol (P) and remimazolam (RM) groups. Patients in the two groups received alfentanil 10 μg/kg, followed by propofol 2 mg/kg and remimazolam 0.15 mg/kg. Blood pressure (BP), heart rate (HR), and oxygen saturation (SpO2) were routinely monitored. The BIS, EMG, and SEF95 were obtained through BIS VISTATM. The primary outcomes were BIS, EMG, and the correlation between BIS and EMG in both groups. Other outcomes were SEF95, the correlation between BIS and SEF95, and the correlation between EMG and SEF95. And all the statistical and comparative analysis between these signals was conducted with SPSS 26.0 and GraphPad Prism 8. BIS values, EMG, and SEF95 were significantly higher in the RM group than in the P group (all p < 0.001). There was a strong positive correlation between BIS and EMG in the RM group (r = 0.416). Nevertheless, the BIS in the P group showed a weak negative correlation with EMG (r = -0.219). Both P (r = 0.787) and RM group (r = 0.559) had a reasonably significant correlation coefficient between BIS and SEF95. SEF95 almost did not correlate with EMG in the RM group (r = 0.101). Bispectral index can be interfered with high EMG intensity under remimazolam anesthesia. However, EMG can hardly affect the accuracy of BIS under propofol anesthesia due to low EMG intensity and a weak negative correlation between EMG and BIS. Moreover, SEF95 may have a great application prospect in predicting the sedation condition of remimazolam.
