Abstract
Remimazolam, a novel intravenous anesthetic, has been proven to be safe and efficacious in the gastroscopy setting among the elderly. However, reports comparing the effectiveness and safety of using equivalent doses of remimazolam with propofol have not been seen. The aim of this study was to compare the sedation efficacy and safety of the 95% effective doses (ED95) of remimazolam versus propofol combined with sufentanil in the gastroscopy setting among the elderly. In the first step of this two-step study, a modified up-and-down method was used to calculate the ED95 of remimazolam and propofol when combined with 0.1 µg/kg sufentanil in inhibiting body movement of elderly patients undergoing gastroscopy. In the second step, ED95 of both agents calculated in the first step were administered, endpoints of efficacy, safety, and incidence of adverse events were compared. A total of 46 individuals completed the first step. The ED95 of remimazolam was 0.163 mg/kg (95% CI 0.160-0.170 mg/kg), and that of propofol was 1.042 mg/kg (95% CI 1.007-1.112 mg/kg). In the second step, 240 patients completed the trial. The anesthetic effective rates of the remimazolam group and the propofol group were 78% and 83%, respectively, with no statistical difference (P = 0.312). Patients in the remimazolam group had more stable circulatory functions (P < 0.0001) and a lower incidence of pain on injection (3.3% vs. 19.5%, P < 0.0001). The incidence of hypotension was low in the remimazolam versus propofol group (15.6% vs. 39.0%, P < 0.0001). Overall adverse event was low in the remimazolam versus propofol group (21.3% vs. 62.7%, P < 0.0001).In this study, we found that when anesthesia was administered to elderly gastroscopy patients based on 95% effective doses of remimazolam and propofol, remimazolam was as effective as propofol, but was safer with a lower incidence of adverse events.Study registration: Chinese Clinical Trial Registry, ChiCTR2000034234.

A randomized, controlled clinical trial comparing remimazolam to propofol when combined with alfentanil for sedation during ERCP procedures. J Clin Anesth 2023; 86:111077. [PMID: 36764022 DOI: 10.1016/j.jclinane.2023.111077] [Citation(s) in RCA: 16] [Impact Index Per Article: 16.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2022] [Revised: 01/09/2023] [Accepted: 02/03/2023] [Indexed: 02/11/2023]
Abstract
STUDY OBJECTIVE In many countries, the combination of propofol and opioid is used as the preferred sedative regime during ERCP. However, the most serious risks of propofol sedation are oxygen deficiency and hypotension. Compared to midazolam, remimazolam has a faster onset and offset of hypnotic effect, as well as cardiorespiratory stability, and to achieve widespread acceptance for procedural sedation, remimazolam must replace propofol which is the most commonly used for procedural sedation. The objective of this study was to compare the safety and efficacy profiles of the remimazolam and propofol when combined with alfentanil for sedation during ERCP procedures. DESIGN A randomized, controlled, single-center trial. SETTING The Endoscopic Centre of Tianjin Nankai Hospital, China. PATIENTS 518 patients undergoing elective ERCP under deep sedation. INTERVENTIONS Patients scheduled for ERCP were randomly assigned to be sedated with either a combination of remimazolam-alfentanil or propofol-alfentanil. MEASUREMENTS The primary outcome was the prevalence of hypoxia, which was defined as SpO2 < 90% for >10 s. Other outcomes were the need for airway maneuver, procedure, and sedation-related outcomes and side effects (e.g., nausea, vomiting, and cardiovascular adverse events). MAIN RESULTS A total of 518 patients underwent randomization. Of these, 250 were assigned to the remimazolam group and 255 to the propofol group. During ERCP, 9.6% of patients in the remimazolam group showed hypoxia, while in the propofol group, 15.7% showed hypoxia (p = 0.04). The need for airway maneuvering due to hypoxia was significantly greater in the propofol group (p = 0.04). Furthermore, patients sedated with remimazolam had a lower percentage of hypotension than patients sedated with propofol (p < 0.001). Patients receiving remimazolam sedation expressed higher satisfaction scores and were recommended the same sedation for the next ERCP. The procedure time in the remimazolam group was much longer than in the propofol group due to the complexity of the patient's disease, which resulted in a longer sedation time. CONCLUSION During elective ERCP, patients administered with remimazolam showed fewer respiratory depression events under deep sedation with hemodynamic advantages over propofol when administered in combination with alfentanil.

Abstract
Objective. To compare the effects of propofol-dexmedetomidine versus propofol-remifentanil for endoscopic ultrasonography (EUS). Design, Setting, and Participants. A single-center, randomized trial from August 20, 2020 to August 20, 2021, in patients undergoing EUS. Interventions. Propofol-dexmedetomidine (PD) versus propofol-remifentanil (PR). Outcome Measures. The primary outcome was the endoscopist satisfaction level. The secondary outcomes included patient satisfaction, the incidence of adverse events, induction time, and time to achieve postanesthesia discharge score (PADS) ≥9. Methods. Total of 200 patients were enrolled and randomized into PD and PR groups. A bolus dose of 0.5 μg/kg dexmedetomidine was injected intravenously for 5 min. Subsequently, a continuous infusion of 0.5 μg/kg/h for the PD group. Remifentanil was continuously infused at 1.5 μg/kg/h for the PR group. A bolus dose of 1 mg/kg propofol was administered to both groups and then continuously infused. Results. The endoscopist satisfaction level was higher in the PR group than in the PD group (
). Patient satisfaction was not significantly different between the groups (
). No patients required mask ventilation or tracheal intubation in both groups. All patients were relatively hemodynamically stable. The incidence of body movements during the procedure in the PD group was higher than in the PR group (
). The induction time and time taken to achieve PADS ≥9 in the PD group were longer than in the PR group (
). Conclusions. PR sedation can increase the satisfaction level of the endoscopist by providing faster induction time and lower body movement and that of the patient by achieving faster PADS than PD sedation. Trial registration number: http://www.chictr.org.cn (ChiCTR2000034987).

Abstract
PURPOSE OF REVIEW Nonoperating room anesthesia for digestive tract endoscopy has its own specificities and requires practical training. Monitoring devices, anesthetic drugs, understanding of procedures and management of complications are critical aspects. RECENT FINDINGS New data are available regarding risk factors for intra- and postoperative complications (based on anesthesia registries), airway management, new anesthetic drugs, techniques of administration and management of advances in interventional endoscopy procedures. SUMMARY Digestive tract endoscopy is a common procedure that takes place outside the operating room most of the time and has become more and more complex due to advanced invasive procedures. Prior evaluation of the patient's comorbidities and a good understanding of the objectives and constraints of the endoscopic procedures are required. Assessing the risk of gastric content aspiration is critical for determining appropriate anesthetic protocols. The availability of adequate monitoring (capnographs adapted to spontaneous ventilation, bispectral index), devices for administration of anesthetic/sedative agents (target-controlled infusion) and oxygenation (high flow nasal oxygenation) guarantees the quality of sedation and patient' safety during endoscopic procedures. Knowledge of the specificities of each interventional endoscopic procedure (endoscopic retrograde cholangiopancreatography, submucosal dissection) allows preventing complications during anesthesia.

Flexible Bronchoscope versus Video Laryngoscope for Orotracheal Intubation During Upper Gastrointestinal Endoscopic Surgery in Left Lateral Position: A Randomized Controlled Trial. Int J Gen Med 2022; 15:6097-6104. [PMID: 35837133 PMCID: PMC9275488 DOI: 10.2147/ijgm.s366020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2022] [Accepted: 06/28/2022] [Indexed: 11/23/2022] Open
Abstract
Purpose Endoscopic submucosal dissection (ESD) has become the primary treatment for early upper gastrointestinal tract lesions. During endoscopic surgery, endotracheal intubation is generally performed in the patients’ supine position, and patients are shifted to the left lateral position for endoscopic surgery. This study compared the efficacy of flexible bronchoscope-guided intubation with that of video laryngoscope-guided intubation in the left lateral position. Patients and Methods Forty-eight patients receiving ESD were randomly divided into the flexible bronchoscope group (group F) or the video laryngoscope group (group V). Tracheal intubation was performed by a trained anesthetist with a flexible bronchoscope (group F) or unchanneled video laryngoscope (group V) in the left lateral position. Primary outcomes included the intubation duration and success rate. Secondary outcomes included the ease of intubation technique and the occurrence of complications. Results Twenty-four (100%) patients in group F and twenty-three (95.8%) in group V were successfully intubated (P = 1.000). The median intubation time in group F was 37s (interquartile range, 33.0, 44.5), which was significantly shorter compared to group V (53s [45.5, 66.5]; P < 0.001). The flexible bronchoscope was significantly easier to manage than the video laryngoscope, as reflected by the users scoring system (9 [9, 10] vs 8 [7, 8]; P < 0.001). The presence of perioperative adverse events and complications were comparable between the two groups. Conclusion Both flexible bronchoscope- and video laryngoscope-guided intubation in patients’ left lateral position achieved high success rates and comparable complication rates. However, intubation with the flexible bronchoscope was completed more quickly.

Abstract
PURPOSE Percutaneous endoscopic gastrostomy (PEG) tube placements are commonly performed pediatric endoscopic procedures. Because of underlying disease, these patients are at increased risk for airway-related complications. This study compares patient characteristics and complications following initial PEG insertion with general endotracheal anesthesia (GETA) vs. anesthesia-directed deep sedation with a natural airway (ADDS). METHODS All patients 6 months to 18 years undergoing initial PEG insertion within the endoscopy suite were considered for inclusion in this retrospective cohort study. Selection of GETA vs. ADDS was made by the anesthesia attending after discussion with the gastroenterologist. RESULTS This study included 168 patients (GETA n=38, ADDS n=130). Cohorts had similar characteristics with respect to sex, race, and weight. Compared to ADDS, GETA patients were younger (1.5 years vs. 2.9 years, p=0.04), had higher rates of severe American Society of Anesthesiologists (ASA) disease severity scores (ASA 4-5) (21% vs. 3%, p<0.001), and higher rates of cardiac comorbidities (39.5% vs. 18.5%, p=0.02). Significant associations were not observed between GETA/ADDS status and airway support, 30-day readmission, fever, or pain medication in unadjusted or adjusted models. GETA patients had significantly increased length of stay (eβ=1.55, 95% confidence interval [CI]=1.11-2.18) after adjusting for ASA class, room time, anesthesia time, fever, and cardiac diagnosis. GETA patients also had increased room time (eβ=1.20, 95% CI=1.08-1.33) and anesthesia time (eβ=1.50, 95% CI=1.30-1.74) in adjusted models. CONCLUSION Study results indicate that younger and higher risk patients are more likely to undergo GETA. Children selected for GETA experienced longer room times, anesthesia times, and hospital length of stay.

Abstract
PURPOSE OF REVIEW Capnography is an excellent tool for early detection of hypoxemia and apnea in patients undergoing sedation for gastrointestinal endoscopy. The current American Society of Anesthesiology (ASA) guidelines recommend the use of capnography in any patient undergoing moderate sedation. The purpose of this review was to compile the most recent data available on capnography use in gastrointestinal endoscopy with the focus primarily on the use of capnography in moderate sedation cases. RECENT FINDINGS Recent high-quality studies have evaluated the utility of capnography in low risk patients undergoing moderate sedation and have found no benefit with addition of capnography. SUMMARY Capnography is beneficial when used for patients who are at a higher risk for sedation-related complications. There is no benefit when capnography is used in low risk patients undergoing routine upper endoscopy and colonoscopy under moderate sedation but there is benefit when used in advanced endoscopic procedures that require deeper sedation and have longer procedure times.
