P0332 Optimization and assessment of colonoscopy preparation in Inflammatory Bowel Disease: a comprehensive single-center analysis with focus on disease-specific factors

Abstract Background Colonoscopy remains a cornerstone in inflammatory bowel disease (IBD) management, yet comprehensive data on preparation quality and tolerability in this specific population remains limited. We aimed to evaluate bowel preparation efficacy, tolerability, and colonoscopy outcomes in IBD patients while analyzing disease-specific influencing factors. Methods We conducted a prospective single-center study of 78 IBD patients (45 ulcerative colitis [UC] and 33 Crohn’s disease [CD]) undergoing routine colonoscopy surveillance. All patients received a split-dose 4L polyethylene glycol preparation. We collected comprehensive data including clinical parameters, Boston Bowel Preparation Scale (BBPS) scores, sedation requirements, and procedure tolerability using Visual Analogue Scale (VAS, 0-100mm). Disease activity was assessed using standardized endoscopic scores. Results Mean age was 47.2 ± 14.5 years for UC and 43.8 ± 13.9 years for CD patients. Adequate bowel preparation (BBPS ≥6) was achieved in 85.7% (67/78) of patients, with a mean total BBPS score of 6.3 ± 1.4. Female patients showed slightly higher preparation quality scores compared to males (BBPS 6.5 ± 1.3 vs 6.1 ± 1.4, p=0.12), though this difference was not statistically significant. Complete colonoscopy was successfully performed in 93.6% (73/78) of cases. No significant differences in BBPS scores were observed between UC and CD patients (6.4 ± 1.5 vs 6.2 ± 1.3, p=0.62), or between patients with active disease versus those in remission (6.3 ± 1.4 vs 6.2 ± 1.5, p=0.85). Preparation tolerability was rated as good or excellent (VAS ≥70) in 76.9% (60/78) of patients, with similar ratings between genders (females: 77.8%, males: 75.9%, p=0.83). Notably, 32.1% (25/78) of IBD patients required increased sedation compared to standard doses, with a higher proportion in CD patients (42.4%, 14/33) compared to UC patients (24.4%, 11/45, p=0.047), and in female patients (37.2%, 16/43) compared to males (25.7%, 9/35, p=0.038). Disease-related factors including disease duration, location, and previous surgery did not significantly impact preparation quality. Conclusion Our study demonstrates that high-quality bowel preparation can be achieved in IBD patients regardless of gender and disease characteristics, with good tolerability rates. However, increased sedation requirements, particularly in CD patients and females, should be anticipated. These findings support the implementation of standardized preparation protocols in IBD patients while emphasizing the need for personalized sedation strategies based on both disease and demographic factors.

Tracheostomy Practice in the Italian Intensive Care Units: A Point-Prevalence Survey.

Background and Objectives: A tracheostomy is a frequently performed surgical intervention in intensive care units (ICUs) for patients requiring prolonged mechanical ventilation. This procedure can offer significant benefits, including reduced sedation requirements, improved patient comfort, and enhanced airway management. However, it is also associated with various risks, and the absence of standardized clinical guidelines complicates its implementation. This study aimed to determine the prevalence of tracheostomy among ICU patients, while also evaluating patient characteristics, complication rates, and overall outcomes related to the procedure. Materials and Methods: We conducted an observational, cross-sectional, point-prevalence survey across eight ICUs in Italy. Data were collected over two 24 h periods in March and April 2024, with a focus on ICU characteristics, patient demographics, the details of tracheostomy procedures, and associated complications. Results: Among the 92 patients surveyed in the ICUs, 31 (33.7%) had undergone tracheostomy. The overall prevalence of tracheostomy was found to be 9.1%, translating to a rate of 1.8 per 1000 admission days. The mean age of patients with a tracheostomy was 59.5 years (SD = 13.8), with a notable predominance of male patients (67.7%). Neurological conditions were identified as the most common reason for ICU admission, accounting for 48.4% of cases. Tracheostomy procedures were typically performed after a mean duration of 12.9 days of mechanical ventilation, primarily due to difficulties related to prolonged weaning (64.5%). Both early and late complications were observed, and 19.35% of tracheostomized patients did not survive beyond one month following the procedure. The average length of stay in the ICU for these patients was significantly extended, averaging 43.0 days (SD = 34.3). Conclusions: These findings highlight the critical role of tracheostomy in the management of critically ill patients within Italian ICUs. The high prevalence and notable complication rates emphasize the urgent need for standardized clinical protocols aimed at optimizing patient outcomes and minimizing adverse events. Further research is essential to refine current practices and develop comprehensive guidelines for the management of tracheostomy in critically ill patients.

Intraoperative virtual reality for older patients undergoing total knee arthroplasty: study protocol for a randomized clinical trial

BackgroundIn an aging surgical patient population, preventing complications such as oversedation has taken increasing priority in perioperative care. Intraoperative use of virtual reality (VR) may decrease sedative requirements. We hypothesize that the use of immersive VR during total knee arthroplasty (TKA) will lead to decreased propofol requirements, improved patient-reported satisfaction, and reduced postoperative opioid requirements compared to active and usual care controls.MethodsThis is a single-center, randomized clinical trial of older (age > 60) patients undergoing TKA. Participants will be randomized into three groups (2:2:1): VR immersion, music, and sham VR plus usual care. All patients will receive a regional block and spinal anesthesia. Patients in the immersive VR and music groups will use patient-controlled sedation (PCS) with propofol, while those in the sham VR group will act as the standard of care control group and will receive monitored anesthesia care (MAC) with propofol infusion.Statistical analysisAnalyses will be conducted using IBM SPSS Statistics Version 25, considering a two-sided p-value < 0.05 to be statistically significant. The primary outcome is the intraoperative dose of propofol (mg kg−1 min−1). Secondary outcomes include patient satisfaction, post-anesthesia care unit (PACU) length of stay, postoperative pain scores and analgesic requirements, functional outcomes, postoperative delirium, and postoperative neurocognition.DiscussionVR used as a non-pharmacological adjunct to regional and spinal anesthesia during TKA may reduce sedative requirements while maintaining patient satisfaction. If true, this approach to minimizing sedation may impact clinical outcomes including perioperative complications and length of stay for older patients, while maintaining a high degree of patient satisfaction.Trial registrationThis trial was registered on ClinicalTrials.gov on January 29, 2021. The registration number is NCT04748549.

Structured pre-delivery huddles enhance confidence in managing newborns with critical congenital heart disease in the delivery room.

Newborns with critical congenital heart disease (CCHD) require specialized delivery room management, but varying experience and knowledge can reduce confidence and impact care. A pre-delivery, structured huddle checklist was introduced, addressing team roles, expected physiology, and management plans. PDSA cycles incorporated guidelines and simulation-based education to improve confidence in specialized resuscitation strategies. Surveys were conducted at baseline and 6 months. Baseline, all-respondent confidence in managing "all types of CCHD" was somewhat confident (median 3/5; IQR 2-4) increasing to moderately confident (4/5; IQR 2-4) at 6 months (p = 0.59). Respondents with 0-3 years' experience showed increased confidence over 6 months in identifying unstable infants (frombaseline24%to 67% moderately/very confident, p = 0.005), prostaglandin E1 needs (from24%to 62%, p = 0.013) and sedation requirements (from5% to 33%, p = 0.045). Structured huddles improved confidence among less experienced team members, emphasizing the importance of shared mental models before CCHD deliveries.

Plasma exchange using peripheral arterial and venous access in the pediatric intensive care unit.

Therapeutic plasma exchange (TPE) is a vital therapeutic modality in pediatric intensive care units (PICU) for various indications. Traditionally, pediatric TPE is performed via a large bore, double lumen catheter, whose insertion necessitates deep sedation, and poses risk of hemorrhagic and thrombotic complications. Building on our previous success utilizing percutaneous radial artery catheters (ALs) for apheresis procedures, we present our experience with ALs for TPE procedures in the PICU. A retrospective cohort study, conducted in the PICU of a tertiary, university affiliated pediatric hospital, including all children aged 19 years and younger, who underwent TPE using an AL for vascular access, between 2018 and 2023. TPE procedures were evaluated for utility (the procedure was performed as planned) and safety. A total of 72 procedures were performed on 20 children, using ALs for inlet access and peripheral intra-venous catheters for blood return. Procedure success rate was 94%, with AL malfunction causing transient delays in 6%. All were successfully completed following AL replacement. ALs were mostly 20 and 22 gauge, predominantly located in the radial artery. AL gauge did not significantly affect flow rate or procedure duration. Our findings support AL use for vascular access, as a viable alternative to the traditional large bore, double lumen catheters most often used for TPE in children. Benefits of AL use may include a decrease in sedation requirements and a lower risk of vascular complications. Further investigation is warranted, for consideration as routine practice in PICUs.

Effect of Music Therapy on Anxiety, Stress and Sedative Requirements in Patients Undergoing Lower Limb Orthopedic Surgery Under Spinal Anesthesia: A Randomized Controlled Study.

Background Music therapy is a safe, non-pharmacological way to help reduce anxiety, especially before surgery. It helps to calm the nervous system, promotes relaxation, and offers comfort by blocking outside noise and distracting from pain. This can be helpful in managing preoperative anxiety and symptoms like hypertension and tachycardia. While the benefits of music therapy for stress and sedation are well known, its specific effects on patients receiving spinal anesthesia haven't been studied yet. Understanding this could improve care for these patients. Overall, music therapy could be a valuable tool in the surgical process. Objectives Primary objective: The study aimed to compare sedative requirements between two patient groups. Secondary objectives: To compare anxiety levels between two patient groupsusing the State-Trait Anxiety Inventory. It also assessed hemodynamic changes and measured stress levels by analyzing serum cortisol and immunoglobulin A levels in both groups. Materials and methods Ninety-two American Society of Anesthesiologists physical status class I and II patients, aged 18-65 years, with a body mass index of 18-25 kg/m2 undergoing lower limb orthopedic surgery under spinal anesthesia were selected for the study. After spinal anesthesia, the group M (n=46)patients received the music of their choice from headphones connected to mobile phones and patients in group NM (n=46)were attached headphones without any music therapy. After the attachment of headphones, propofol was administered in both the groups for sedation in a bolus dose of 1-2mg/kg iv followed by an infusion dose of 5-50 μg/kg/min. The propofol infusion was titrated based on Bispectral Index (BIS) values kept between 70 and 80 for moderate sedation. Preoperatively, blood samples were collected to measure baseline serum cortisol and IgA levels. Intraoperatively, hemodynamic parameters were measured, and anxiety level was assessed using the State-Trait Anxiety Inventory (STAI) Scale 30 minutes prior to the administration of spinal anesthesia. Postoperatively, anxiety was re-evaluated, and additional blood samples for the assessment of cortisol and IgA were taken at 30 minutes and 12 hours after the administration of spinal anesthesia. Results The mean serum cortisol was lower in Group M as compared to Group NM (15.1±1.2 vs. 17.1±1; p = 0.0001). Mean serum IgA was significantly lower in Group M as compared to Group NM (269.3±54.5 vs. 294.2±49.9; p = 0.024) during the intraoperative period. The mean STAI Score was lower in Group Mcompared to Group NM (34.87±4.53 vs. 34.61±5.06; p = 0.008). The mean propofol requirement (mg) was lower in Group M as compared to Group NM (147.8±11.3 vs. 193±16; p = 0.0001). The hemodynamic parameters were comparable between the groups (p>0.05). Conclusion Patients in the music therapy group experienced lower anxiety, stress, and serum cortisol levels during surgery, with reduced serum IgA levels and decreased propofol requirement for sedation. Overall, music therapy was effective in reducing anxiety, stress, and sedative requirements during surgery under regional anesthesia.

Evaluation of an Australian community‐based model of care for adults with intellectual and developmental disabilities undergoing procedures under sedation

AbstractBackgroundAdults with intellectual and developmental disabilities (IDDs) have higher healthcare needs, but experience difficulties accessing preventative healthcare. Despite this inequity, models of care that address barriers and provide customized treatment are limited, exacerbating vulnerabilities and poorer health outcomes. This study describes the development of a procedural model of care (PMOC) for adults with intellectual and developmental disabilities, and evaluates the sedation tier, exploring procedure and sedation outcomes.MethodsDevelopment of the PMOC was informed by current evidence and themes identified in stakeholder consultation and literature. A retrospective cohort study evaluated the sedation option within the model, conducted at a community‐based disability service in Melbourne, Australia. All records over a 14‐month period were included. Descriptive statistics and univariate logistic regression analysis were used to analyze data.ResultsThe PMOC includes assessment, intervention, and evaluation tiers. Intervention options range from least to most invasive, culminating in the sedation level (mild; oral psychoactive, moderate; midazolam and nitrous oxide, high; general anesthetic). A total of 127 adults with IDDs received procedures under sedation; median age was 26 years, 61% lived with family, and 81% had multiple disabilities. A total of 197 procedures were referred to CDDH, including immunization (61%) and oral health reviews (23%), and resulted in 98% completion rate. Mild (n = 36) and moderate (n = 95) sedation were used for 67% of procedures. The PMOC correctly predicted 91% of sedation requirements. Living with family (OR 2.211, 95% CI 1.001–4.885, p = 0.05); immunization (OR 7.935, 95% CI 4.025–15.644, p &lt;0.001); and multiple disabilities (OR 3.064, 95% CI 1.123–8.362, p = 0.029) were associated with mild, moderate and high sedation options, respectively.ConclusionsModels of care offering individualized interventions can support adults with IDDs to receive preventative procedures. Demographic variables may be able to predict sedation requirements. Wider application of this model may reduce health inequity within this vulnerable population.

Comparative Study between Dexmedetomidine and Fentanyl as Adjuvants to Bupivacaine for Prevention of Post Spinal Shivering in Caesarean Sections

Abstract Background Shivering is a common complication in regional anesthesia during cesarean sections. It can impair monitoring and increase oxygen demand, CO2 production, and wound pain, healing, and discharge. Spinal anesthesia can increase vulnerability to hypothermia, leading to shivering. Dexmedetomidine and fentanyl have been shown to prevent post-spinal shivering. Aim of the Work This study aimed to compare the efficacy and safety of fentanyl and dexmedetomidine in preventing perioperative shivering and their effects on block intensity, hemodynamics, sedation, postoperative pain, and analgesic requirement. Patients and Methods 150 obstetric patients were included and randomized into three equal groups: control, fentanyl, and dexmedetomidine group. Each group received 12.5 mg hyperbaric bupivacaine 0.5% intrathecally with different adjuvants. Results Both fentanyl and dexmedetomidine groups showed a decreased incidence and intensity of shivering compared to the control group. There was no statistically significant difference between the two groups in this regard (p-value &amp;gt;0.05). The onset and duration of sensory and motor block were faster and prolonged in both fentanyl and dexmedetomidine groups compared to the control group, but dexmedetomidine showed faster onset and more prolonged duration than fentanyl. Dexmedetomidine also showed a statistically significant difference regarding hypotension (p-value &amp;lt;0.05) but non-significant regarding bradycardia (p-value &amp;gt;0.05) compared to other groups. There were no statistically significant differences in sedation intensity between the groups (p-value &amp;gt;0.05). Fentanyl showed a higher incidence of nausea, vomiting, and pruritis compared to other study groups. Conclusion Both fentanyl and dexmedetomidine are safe to use with bupivacaine for prevention of perioperative shivering in cesarean sections. Both drugs decreased the incidence and intensity of shivering, and dexmedetomidine was more effective in terms of prolongation of sensory and motor block duration and reducing opioid requirements. Dexmedetomidine showed fewer side effects during the intra and postoperative period compared to fentanyl.

“Comparison between high-flow nasal cannula (HFNC) therapy and noninvasive ventilation (NIV) in children with acute respiratory failure by bronchiolitis: a randomized controlled trial”

BackgroundThe objective of this study was to compare HFNC therapy to noninvasive ventilation (NIV/BiPAP) in children with bronchiolitis who developed respiratory failure. We hypothesized that HFNC therapy would not be inferior to NIV.MethodsThis was a noninferiority open-label randomized single-center clinical trial conducted at a tertiary Brazilian hospital. Children under 2 years of age with no chronic conditions admitted for bronchiolitis that progressed to mild to moderate respiratory distress (Wood-Downes-Férres score < 8) were randomized to either the HFNC group or NIV (BiPAP) group through sealed envelopes. Vital signs, FiO2, Wood-Downes-Férres score and HFNC/NIV parameters were recorded up to 96 h after therapy initiation. Children who developed respiratory failure despite receiving initial therapy were intubated. Crossover was not allowed. The primary outcome analyzed was invasive mechanical ventilation requirement. The secondary outcomes were sedation usage, invasive mechanical ventilation duration, the PICU LOS, the hospital LOS, and mortality rate.ResultsA total of 126 patients were allocated to the NIV group (132 randomized and 6 excluded), and 126 were allocated to the HFNC group (136 randomized and 10 excluded). The median age was 2.5 (1–6) months in the NIV group and 3 (2–7) months in the HFNC group (p = 0,07). RSV was the most common virus isolated in both groups (72% vs. 71.4%, NIV and HFNC, respectively). Thirty-seven patients were intubated in the NIV group and 29 were intubated in the HFNC group (29% vs. 23%, p = 0.25). According to the Farrington-Manning test, with a noninferiority margin of 15%, the difference was 6.3% in favor of HFNC therapy (95% confidence interval: -4.5 to 17.1%, p < 0.0001). There was no significant difference in the PICU LOS or sedation duration. Sedation requirement, hospital LOS and invasive mechanical ventilation duration were lower in the HFNC group.ConclusionHFNC therapy is noninferior to NIV in infants admitted with mild to moderate respiratory distress caused by bronchiolitis that progresses to respiratory failure.Trial registration numbersU1111-1262-1740; RBR-104z966s.

Comparison of Hemodynamic and Recovery Profile Between Segmental Thoracic Spinal and General Anesthesia in Upper Abdominal and Breast Surgeries: A Systematic Review and Meta-Analysis.

Segmental thoracic spinal anesthesia (STSA) has been described primarily as case reports for performing upper abdominal and thoracic surgeries in significant respiratory comorbid patients. A few comparative studies have recently evaluated the technique as an advantageous alternative to general anesthesia (GA). However, there is no systematic evaluation and comparison of the techniques. The present systematic review evaluated the hemodynamic, comfort, and satisfaction of patients undergoing abdominal and thoracic surgeries under STSA and GA. PubMed, CENTRAL, Google Scholar Advanced, and citation tracking were performed to find suitable articles that compared STSA and GA. The primary objective-related data were hypotension and bradycardia. The secondary objective-related data in the context of postoperative nausea vomiting (PONV), pain, rescue analgesics, sedation requirement, satisfaction, and comfort were assessed. Meta-analysis was performed for dichotomous data on hypotension, bradycardia, and PONV; odds ratio (OR) and 95% confidence interval (CI) were reported. Data of 394 patients from six studies were evaluated. Patients undergoing upper abdominal and breast surgeries under STSA had significantly higher odds of hypotension (Fixed-Effect Model OR 12.23, 95% CI 2.81-53.28; I2 =0%, and the Random Effects Model OR 12.01, 95% CI 2.75-52.52; I2 =0%) and bradycardia (Fixed-Effect Model OR 10.95, 95% CI 2.94-40.74, I2 =0%, and the Random Effects Model OR 9.97, 95% CI 2.61-38.08; I2 =0%) but lower odds of PONV (Fixed-Effect Model OR 0.24, 95% CI 0.13-0.43; I2 =0%, and the Random Effects Model OR 0.24, 95% CI 0.13-0.45; I2 =0%). Most of the patients undergoing STSA were given intravenous sedation to overcome anxiety and discomfort. Overall, patient satisfaction was on par with GA. However, few surgeons were unenthusiastic about the technique while performing axillary clearances due to bothering twitches from cautery. STSA led to early post-anesthesia care unit (PACU) discharge and provided better pain control, lowering the need for rescue analgesics and opioid consumption in the first 24-hour postoperative period. STSA is associated with very high odds of hypotension and bradycardia as compared to GA. On the other hand, STSA demonstrated superior pain control, reduced opioid requirements, shorter PACU stays, and significantly reduced risk of PONV. Nevertheless, STSA patients mostly require sedation to make the patient comfortable.

The Effectiveness of Virtual and Augmented Reality in Surgical Pain Management: A Systematic Review of Randomized Controlled Trials.

Satisfactory management of postoperative pain remains challenging. Nonpharmacological modalities such as virtual and augmented reality (VR/AR) offer potential benefits and are becoming increasingly popular. This systematic review evaluates the effectiveness and safety of VR/AR interventions on postoperative pain and recovery. MEDLINE, Embase, CINAHL, Web of Science, and CENTRAL databases were searched from inception to July 27, 2023, for randomized controlled trials (RCTs), published in English, evaluating the use of VR/AR interventions for surgical pain relief. Study selection and data extraction were performed by pairs of reviewers independently and in duplicate, and potential risk of bias was determined using the Risk of Bias-version 2 (RoB 2) tool. Our outcomes included pain relief, reduction of anxiety, satisfaction, and adverse effects. Due to substantial heterogeneity, a narrative synthesis without meta-analysis was performed. We included 35 trials among 2257 citations, categorized as surgery (n = 12), minor procedures (n = 15), and postoperative physiotherapy (n = 8). Surgical group included various surgeries, with 11 using immersive VR predominantly in the postoperative period, and most reporting no differences in pain, but potential for reduced anxiety and sedation requirements. In the minor procedures group, most studies reported decreased pain and anxiety during the procedural performance. Two studies reported increased heart rate, while 2 others reported better hemodynamic stability. Home-based AR physiotherapy achieved (n = 6) similar pain and functional outcomes after knee replacement, with 1 large study (n = 306) reporting reduction of mean costs by $2745 for provision of 12 weeks physiotherapy. There were some concerns around potential bias for most studies, as the nature of interventions make it challenging to blind assessors and participants. No important adverse effects were noted using VR/AR technology. Evidence from RCTs indicates that the use of immersive VR during minor procedures may reduce procedural pain, decrease anxiety, and improve satisfaction. However, small studies, inconsistent effect, and variation in the application of interventions are important limitations. Evidence to support the application of AR/VR for major surgeries is limited and needs to be further investigated. Use of home-based physiotherapy with AR likely has economic advantages, and facilitates virtual care for appropriate patients who can access and use the technology safely.

The Feasibility, Safety and Outcome of Very High-Power Short Duration Radiofrequency Ablation in Pulmonary Vein Isolation: A Real-World Observation Study.

Pulmonary vein isolation (PVI) ablation is the established gold standard therapy for patients with symptomatic drug refractory atrial fibrillation (AF). Advancements in radiofrequency (RF) ablation, have led to the development of the novel contact force-sensing temperature-controlled very high-power short-duration (vHPSD) RF ablation. This setting delivers 90 W for up to 4 seconds with a constant irrigation flow rate of 8 mL/min. The aim of this study was to compare procedural outcomes and safety with conventional radiofrequency ablation. An observational study was conducted with patients who underwent first time PVI ablation between August 2020 and January 2022. The cohort was divided into: (1) vHPSD ablation; (2) High-power short duration (HPSD) ablation; (3) THERMOCOOL SMARTTOUCH™ SF (STSF). The vHPSD ablation group was prospectively recruited while the HPSD and STSF group were retrospectively collected. Primary outcomes were procedural success, PVI duration, ablation duration and incidence of perioperative adverse events. Secondary outcomes were intraprocedural morphine and midazolam requirement. A total of 175 patients were included in the study with 100, 30 and 45 patients in the vHPSD, HPSD and STSF group, respectively. PVI was successfully attained in all vHPSD patients. vHPSD demonstrated significantly reduced time required for PVI and total energy application in comparison to the HPSD and STSF groups (67.7 29.7 vs. 92.9 25.7 vs. 93.6 29.1 min, p 0.0001; 9.87 4.16 vs. 33.9 7.49 vs. 36.0 10.5 min, p 0.0001, respectively). Intravenous morphine and midazolam requirement was lower in the vHPSD group compared to the HPSD and STSF groups (10.2 3.43 vs. 16.1 4.58 vs. 15.3 3.94 mg, p 0.0001; 4.04 3.24 vs. 8.63 5.22 vs. 8.58 4.72 mg, p 0.0001). One cardiac tamponade was observed in both the vHPSD and HPSD groups while the STSF group exhibited an embolic stoke and two pericardial effusions that did not require drainage. In this study, vHPSD demonstrated a comparable safety profile to the other treatment arms. Procedural duration and energy application time was substantially reduced along with sedation requirement notwithstanding the limitations of observational study design, these preliminary findings are promising with respect to periprocedural outcomes and safety of vHPSD however longitudinal outcomes will be essential to assessing the overall efficacy of this novel technology.

Effects of Cannabis Use on Sedation Requirements for Endoscopic Procedures: A Replication Study.

On July 1, 2021, cannabis became legal in Virginia for adults 21years 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.

A Retrospective Cohort Analysis of Analgosedation Requirements in COVID-19 Compared to Non-COVID-19 Extracorporeal Membrane Oxygenation Patients.

Reports have described increased sedation requirements in patients with acute respiratory distress syndrome (ARDS) while on extracorporeal membrane oxygenation (ECMO) and for intubated COVID-19 patients. Thus, the objective of this study was to assess the analgosedation requirements of COVID-19 patients receiving ECMO compared to non-COVID-19 ECMO patients. This retrospective, observational cohort study included adult patients with ARDS requiring venovenous or venopulmonary arterial ECMO admitted to a single intensive care unit from January 2017 to December 2021. Patients were categorized as COVID-19 ECMO or non-COVID-19 ECMO. The primary outcome was median daily dosing of parenteral analgosedative medications. Pertinent secondary outcomes included incidence of extubation or tracheostomy and change in sedation following tracheostomy or addition of oral agents. A total of 109 patients were evaluated; 63 COVID-19 ECMO patients and 46 non-COVID ECMO patients. The primary outcome was statistically higher in the COVID-19 compared to non-COVID-19 patients for propofol (4131.0 mg vs 2704.8 mg, P < .001), dexmedetomidine (1581.4 mcg vs 1081.3 mcg, P = .016), and parenteral morphine equivalents ([PME], 209.3 mg vs 154.1 mg, P = .027), but only propofol remained significant after adjustment for weight (31.1 mcg/kg/day vs 37.7 mcg/kg/day, P = .014). COVID-19 was significantly associated with increased propofol and PME requirements after adjustment for confounders on linear regression analysis. COVID-19 patients had more days with non-zero dose for propofol (8 days vs 7 days), dexmedetomidine (13 days vs 8.5 days), and PME (17 days vs 8.5 days). The only interventions that were associated with reductions in propofol dose were tracheostomy and antipsychotics. COVID-19 patients on ECMO had significantly longer durations and higher doses of propofol, dexmedetomidine, and parenteral opioids over the first 28 days of cannulation. The only interventions that were associated with statistical reductions in propofol were antipsychotics and tracheostomy.

The Effects of Music Therapy on Patients Undergoing Colonoscopy in a Tertiary Care Hospital at Karachi, Pakistan: A Comparative Study

A colonoscopy is a procedure commonly used for the diagnosis of colorectal diseases but may be associated with high levels of anxiety and discomfort, which can lead to complications during sedation and decreased patient comfort and cooperation. This study was conducted at a tertiary care hospital in Karachi to assess the effectiveness of music therapy on pre-procedural anxiety, sedation requirements, pain, and procedure duration among patients undergoing colonoscopies. This comparative study included 110 outpatients. The intervention arm received non-lyrical soft music through earphones before and during the colonoscopy procedure, while the control group did not receive any music. In the intervention arm, significant reductions were seen in pre-procedural anxiety scores (p < 0.001), physiological measures (p < 0.001), sedation doses (p < 0.001), and procedure durations (p < 0.05). Control arm showed an increase in heart rate and systolic blood pressure (p < 0.001). Pain scores were similar for both groups. Music therapy is an effective tool to reduce patient anxiety pre- procedure. It is a simple, safe, and noninvasive relaxing intervention that could be used as an adjunct to sedative medications before and during the colonoscopy procedure.

Comparison of dexmedetomidine versus propofol sedation on microcirculation and organ injuries in critically ill surgical patients: A randomized controlled pilot study

BACKGROUND: Recent studies have shown that dexmedetomidine may improve microcirculation and prevent organ failure. However, most evidence was obtained from experimental animals and patients receiving cardiac surgery with cardiopulmonary bypass. This study aimed to investigate the effect of dexmedetomidine on microcirculation and organ injuries in critically ill general surgical patients. METHODS: In this prospective randomized trial, patients admitted to the surgical intensive care unit after general surgery were enrolled and randomly allocated to the dexmedetomidine or propofol groups. Patients received continuous dexmedetomidine or propofol infusions to meet their requirement of sedation according to their grouping. At each time point, sublingual microcirculation images were obtained using the incident dark field video microscope. RESULTS: Overall, 60 patients finished the trial and were analyzed. Microcirculation parameters did not differ significantly between two groups. Heart rate at 4 h after ICU admission and mean arterial pressures at 12 h and 24 h after ICU admission were lower in the dexmedetomidine group than in the propofol group. At 24 h, serum aspartate aminotransferase (41 (25–118) vs 86 (34–129) U/L, p = 0.035) and alanine aminotransferase (50 (26–160) vs 68 (35–172) U/L, p = 0.019) levels were significantly lower in the dexmedetomidine group than in the propofol group. CONCLUSION: Microcirculation parameters did not differ significantly between the dexmedetomidine and propofol groups. At 24 h after ICU admission, serum liver enzyme levels were lower in patients receiving dexmedetomidine as compared to propofol.

Tracheostomy Timing in Unselected Critically Ill Patients with Prolonged Intubation: A Prospective Cohort Study.

Background: Tracheostomy procedures are performed in the intensive care unit (ICU) for prolonged intubation, unsuccessful weaning and infection prevention through either percutaneous or surgical techniques. This study aimed to outline the impact of tracheostomy timing in the ICU on mortality, need for mechanical ventilation, and complications. Methods: Patients were included in the study on the day of tracheostomy. Demographic information, tracheostomy timing, technique, complications, sedation requirement and need for mechanical ventilation at discharge were recorded by an anesthesiologist, including the pre-tracheostomy period. Results: Tracheostomy was performed on 33 patients during the first 14 days of intubation and on 54 patients on the 15th day and beyond. There was no significant difference between the tracheostomy timing and mortality, sedation requirement, or weaning from the ventilator. We observed that patients who underwent tracheostomy with the surgical technique experienced more complications, but there was no significant difference. Tracheostomy performed after the 14th day was shown to be associated with prolonged hospital stay. Conclusions: Early tracheostomy does not have any influence on the need for mechanical ventilation, sedation and mortality. The optimal timing for tracheostomy is still controversial. We are of the opinion that randomized controlled trials involving patient groups with similar survival expectations are needed.

Randomised trial of ‘hybrid’ water-assisted colonoscopy (modified water immersion) versus water exchange colonoscopy: WAVE study

Background and aimsColonoscopy practice has evolved with a trend towards water-assisted insertion. A recent national survey suggests a hybrid approach to colonic distension during insertion, with water used predominately to...

Safety of remimazolam in comparison with midazolam for colonoscopy: A systematic review and meta-analysis

Background Remimazolam is an ester-based ultra-short-acting benzodiazepine that efficiently achieves sedation within a short period and is now being assessed as a suitable alternative to midazolam. This meta-analysis aims to pool the available data assessing and focusing on the safety aspect of remimazolam compared with midazolam. Methods A multi-center randomized control trial for patients undergoing endoscopic procedures like colonoscopy was conducted, comparing remimazolam to placebo for the midazolam group as the intervention group. The safety of remimazolam was the primary endpoint of this meta-analysis. Results A total of 3 studies were included. The total study population was 697, including the placebo, remimazolam, and midazolam groups. The types of studies included are i. randomized, double-blind, parallel-group, active-controlled clinical trial ii. prospective, randomized, parallel-group study comparing remimazolam to placebo (blindly), RCT, and iii. prospective, double-blind, randomized, parallel-group study RCT.; Treatment-emergent adverse effects included vascular disorders (P=0.42), cardiac disorders (p=0.06), respiratory, thoracic, and mediastinal disorders (p=0.26), infections and infestations (0.88), hematologic abnormalities such as anemia (p=0.63), and derangements in Blood pressure (systolic p=0.47 and diastolic p=0.68 and respiratory parameters (p=0.34). Analysis of the reported data suggests that the remimazolam group had a significantly higher incidence of treatment-emergent adverse effects compared to the midazolam group (RR: 0.84; 95% CI [0.78, 0.91]; P &lt;0.00001; I2 = 5%). Conclusions In conclusion, this meta-analysis of three randomized controlled trials showed outcomes favoring both remimazolam and midazolam as successful sedatives, yet the higher requirement of top-up dosage and rescue sedatives in the midazolam group indicates that remimazolam can be used as its replacement, especially in colonoscopy procedures.
