Brohan M, Brohan J, Goudra B. Remimazolam and Its Place in the Current Landscape of Procedural Sedation and General Anesthesia. J Clin Med 2024; 13:4362. [PMID: 39124629 PMCID: PMC11312559 DOI: 10.3390/jcm13154362] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2024] [Revised: 07/19/2024] [Accepted: 07/24/2024] [Indexed: 08/12/2024] Open
Abstract
Remimazolam was derived from its parent compound by adding an ester linkage into its structure so that the drug becomes a substrate for ester metabolism. As a result, it undergoes organ-independent ester hydrolysis, although the clinical benefits in terms of shorter recovery are not uniformly observed in clinical practice. Remimazolam is mainly tested in procedural sedation. In comparison to propofol, the current gold standard for procedural sedation, its proposed attractiveness is shorter wake-up times and a clear-headed recovery. Its clear advantages over propofol are better hemodynamic stability, lack of pain on injection and availability of a reversal agent in the form of flumazenil. Data on patient and proceduralist satisfaction are lacking. Remimazolam is also used for induction and maintenance of general anesthesia in Japan (where it is approved for this purpose). In this scenario, it is not clear if it can achieve the same degree of lack of recall as propofol. The use of remimazolam in obstetrics, pediatrics and high-risk populations is an emerging area.

Safety and efficacy of physician-administered balanced-sedation for the endoscopic mucosal resection of large non-pedunculated colorectal polyps. Endosc Int Open 2024; 12:E1-E10.

Abstract
Background and study aims Because of concerns about peri-procedural adverse events (AEs), guidelines recommend anesthetist-managed sedation (AMS) for long and complex endoscopic procedures. The safety and efficacy of physician-administered balanced sedation (PA-BS) for endoscopic mucosal resection (EMR) of large non-pedunculated colorectal polyps (LNPCPs) ≥20 mm is unknown. Patients and methods We compared PA-BS with AMS in a retrospective study of prospectively collected data from consecutive patients referred for management of LNPCPs (NCT01368289; NCT02000141). A per-patient propensity analysis was performed following a 1:2 nearest-neighbor (Greedy-type) match, based on age, gender, Charlson comorbidity index, and lesion size. The primary outcome was any peri-procedural AE, which included hypotension, hypertension, tachycardia, bradycardia, hypoxia, and new arrhythmia. Secondary outcomes were unplanned admissions, 28-day re-presentation, technical success, and recurrence. Results Between January 2016 and June 2020, 700 patients underwent EMR for LNPCPs, of whom 638 received PA-BS. Among them, the median age was 70 years (interquartile range [IQR] 62-76 years), size 35 mm (IQR 25-45 mm), and duration 35 minutes (IQR 25-60 minutes). Peri-procedural AEs occurred in 149 (23.4%), most commonly bradycardia (116; 18.2%). Only five (0.8%) required an unplanned sedation-related admission due to AEs (2 hypotension, 1 arrhythmia, 1 bradycardia, 1 hypoxia), with a median inpatient stay of 1 day (IQR 1-3 days). After propensity-score matching, there were no differences between PA-BS and AMS in peri-procedural AEs, unplanned admissions, 28-day re-presentation rates, technical success or recurrence. Conclusions Physician-administered balanced sedation for the EMR of LNPCPs is safe. Peri-procedural AEs are infrequent, transient, rarely require admission (<1%), and are experienced in similar frequencies to those receiving anesthetist-managed sedation.

Abstract
INTRODUCTION Worldwide, gastrointestinal endoscopies are predominantly performed under sedation. National and international guidelines and recommendations contain very different specifications for the use of sedation in gastrointestinal endoscopy. These differences come from specific requirements for staffing during endoscopy. AIM The aim of the study is to evaluate whether endoscopist-guided sedation without additional sedation assistance is not inferior to endoscopist-guided sedation with additional sedation assistance with respect to the rate of sedation-associated complications in a defined low-risk population (low-risk procedure and low-risk patient). METHODS Prospective, multicenter, randomized study. RESULTS 27 German study centers participated in the study. A total of 30 569 endoscopies were recorded during the study period from 1.8.2015 to 10.3.2020. The final data analysis included 28 673 examinations (64.1 % esophagosgastroduodenoscopies and 35.9 % colonoscopies). In 307 (1.1 %) examinations, 322 sedation-associated complications occurred. Of these, 321 (1.1 %) were minor complications and one (0.003 %) was a major complication. There was no statistically significant difference in the frequency of sedation-associated complications between endoscopist-guided sedation with versus without additional sedation assistance. Within the legal framework, a "shadow" sedation assistant was present in the study group without sedation assistance. This assistant intervened because of sedation-associated complications in 101 (0.7 %) of the endoscopies. CONCLUSION The study documents the safety of propofol-based endoscopist-guided sedation in a low-risk population. In 98.9 % of all endoscopies, no sedation-associated complication occurred or it was so minimal that no intervention (e. g., increase of oxygen supply) was necessary. The study cannot answer to what extent a serious complication was avoided by the active intervention of the "shadow" sedation assistance in the group without sedation assistance.The study proves in a randomized, prospective design that sedation in low-risk endoscopy (low-risk patient, low-risk procedure) can be performed as endoscopist-guided sedation without additional sedation assistance, without demonstrably accepting a reduction in safety.

Bilevel positive airway pressure for gastroscopy with sedation in patients at risk of hypoxemia: A prospective randomized controlled study. J Clin Anesth 2023; 85:111042. [PMID: 36549036 DOI: 10.1016/j.jclinane.2022.111042] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Revised: 12/03/2022] [Accepted: 12/15/2022] [Indexed: 12/24/2022]
Abstract
STUDY OBJECTIVE Hypoxemia is one of the most frequent adverse events during sedated gastroscopy, and there is still no effective means to prevent and cure it. Therefore, we conducted this randomized trial to confirm our hypothesis that, compared with the nasal cannula group, bilevel positive airway pressure (BPAP) would decrease the incidence of hypoxemia in patients with obstructive sleep apnea (OSA) or overweight status undergoing gastroscopy. DESIGN In a single-center, prospective, randomized controlled clinical trial, 80 patients aged 18-65 years and with OSA or overweight status who underwent gastroscopy with sedation were randomly assigned to two groups: the nasal cannula and BPAP groups. The primary outcome was the incidence of hypoxemia (75% < peripheral oxygen saturation [SpO2] < 90% for >5 sand <60 s). MAIN RESULTS Compared to the nasal cannula group, BPAP therapy significantly decreased the incidence of hypoxemia from 40.0% to 2.5% (absolute risk difference [ARD], 37.5% [95% confidence interval (CI), 21.6 to 53.4], p < 0.001), decreased subclinical respiratory depression from 52.5% to 22.5% (ARD, 30.0% [95% CI, 9.8 to 50.2], p = 0.006), and decreased severe hypoxemia from 17.5% to 0% (ARD, 17.5% [95% CI, 5.7 to 29.3], p = 0.006). The BPAP intervention also decreased the total propofol dosage and operation time and improved anesthesiologist's satisfaction. CONCLUSION BPAP therapy significantly decreased the incidence of hypoxemia in patients with OSA or overweight status who underwent gastroscopy.

Indian J Gastroenterol 2022; 41:583-590. [PMID: 36576697 DOI: 10.1007/s12664-022-01291-y] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/05/2021] [Accepted: 07/31/2022] [Indexed: 12/29/2022]
Abstract
BACKGROUND Optimum procedural sedation is very essential for conducting non-operating room procedures such as endoscopic retrograde cholangiopancreatography (ERCP). The combination of ketamine and dexmedetomidine (KD) is expected to balance out the undesirable effects of either drug and provide smooth sedation. Together ketamine and propofol (KP) also provide synergistic sedation with stable hemodynamics. This prospective, single-blinded randomized study aimed to compare the effect of both the combinations during ERCP in terms of oxygen desaturation, respiratory depression, hemodynamic parameters, analgesia, recovery time, and ease with which the endoscopist could perform the endoscopy. METHODS This prospective, single-blinded randomized study (CTRI/2019/08/020625) was conducted on 84, ASA (American Society of Anesthesiologists) physical status I or II patients, of age 18-65 years presenting for ERCP in a tertiary care center. They were randomized to receive either KD (n=42) or KP (n=42) combination during ERCP. Mean SPO2 at the end of the procedure was compared between the groups. Apart from these periprocedural hemodynamic and respiratory parameters, pain scores on arrival in the recovery room (t0), 15 minutes (t15), and 30 minutes (t30), recovery time, and endoscopist's satisfaction as per a Likert's scale were recorded. RESULTS The mean SpO2 (SpO2 recorded every minute during the procedure and averaged over procedure time in minutes) in group KP (97.7 [96.1-98.6]) was significantly lower than group KD (98.5 [98.1-98.8]) (p=0.005). The post-procedure pain scores measured at t0 and t15 were higher in group KP (p<0.001 and p=0.043), and comparable at t30 in both the groups (p=0.711). The time to achieve Modified Aldrete score (MAS) ≥ 9 was significantly more in group KD (p<0.001). The lowest mean arterial pressure and heart rate in group KD were significantly lower than in group KP (p<0.001, p=0.006, respectively). The overall endoscopist satisfaction was better in group KP compared to group KD (p= 0.011). CONCLUSIONS The combination of ketamine-dexmedetomidine for procedural sedation during ERCP is a safe alternative to ketamine-propofol with a better respiratory profile.

Abstract
Propofol-based sedation provides faster recovery than midazolam-based regimens with similar safety and comfort during video flexible bronchoscope (VFB) procedures. Pulmonologist-administered propofol "balanced" analgosedation (PAP-BAS) is still debated in Italy. In this real-life study, PAP-BAS safety and comfort during VFB procedures were investigated. We analysed prospectively the subjects undergoing elective VFB procedures in the Pulmonology and RICU of Arezzo Hospital between February and July 2019. PAP-BAS combined low propofol and meperidine doses titrated to achieve an RASS score between 0 and -3. The primary end-point was the complications' rate. Secondary end-points were as follows: the relation between propofol's dose and a subject's comfort assessed with a VAS, recovery time according to a modified Aldrete score ≥9, RASS, and subjects' will of undergoing the procedure again. We collected postprocedure symptoms' intensity too. Our 158 study patients (67 years; SD ± 14; 64% males) incurred in 25% of complication, fully resolved with medical therapy. Neither recourse to ventilator support nor death was reported. Intraprocedural comfort was good (94% of VAS score ≤2). Among postprocedural symptoms, cough was the most frequently reported, in 36% of the cases. Although half of subjects remembered the procedure, 90% of them would have repeated it, if necessary. 85% of them recovered from procedures within 10 minutes. Complications, VAS, and recovery time were not correlated with propofol dose. To our knowledge, this is the first Italian study showing that PAP-BAS to perform a VFB procedure is safe, well tolerated with a quick recovery. Randomised controlled trials are warranted to confirm these preliminary results.

Abstract
With the increase in health consciousness and the prevalence of early gastrointestinal cancer screening, the number of diagnosed cases of colorectal polyps and adenomas in the Chinese general population has substantially increased. However, the overall adenoma detection rate (ADR) in China remains lower than the global standard of 30%. High quality colonoscopy is pivotal for increasing the ADR and reducing the risk of interval colon cancer. A few factors are related to the quality of colonoscopy, including preoperative evaluation of examinees, bowel preparation, techniques for intubation, use of image enhancement endoscopy, withdraw time, and prevention of adverse events.

Abstract
Background/Aims The intensities of injection pain resulting from the use of long- and medium-chain triglyceride (LCT/MCT) propofol and conventional LCT propofol during esophagogastroduodenoscopy (EGD) have yet to be compared. We aimed to determine the pain intensity caused by different formulations of propofol and to evaluate the formulation that would be preferred by patients as a sedative agent during their next procedure. Methods This study was a single-center, randomized, controlled, and double-blind trial. Pain intensity was estimated 30 seconds after propofol injection by an examiner who was blinded to the group assignment using a numeric (0-10) pain rating scale (NPRS). After 1 week, the patients were asked whether they could recall the pain and were willing to receive the same agent for their next EGD. Results One hundred twenty-nine patients were randomly assigned to LCT/MCT or LCT group. Although there was no significant difference in pain incidence between the LCT/MCT and LCT groups (52.9% vs 65.6%, p=0.156), the pain intensity was significantly lower in the LCT/MCT group (NPRS median [interquartile range]; 1 (0-2) vs 2 (0-5), p=0.005). After 1 week, fewer patients in the LCT/MCT group recalled the pain (19.1% vs 63.9%, p<0.001) and more patients in the LCT/MCT group were more willing to use the same agent for their next procedure (86.8% vs 72.1%, p=0.048) than in the LCT group. Conclusions LCT/MCT propofol significantly reduced injection pain intensity compared to LCT propofol during EGD and preferred by patients as a sedative agent during their next EGD.

Abstract
Background and study aims Efficacy and safety of NAAP for gastrointestinal endoscopy have been widely documented, although there is no information about the outcomes of colonoscopy when the endoscopist supervises the sedation. In this context, the aim of this trial was to determine the equivalence of adenoma detection rate (ADR) in colorectal cancer (CRC) screening colonoscopies performed with non-anesthesiologist-administered propofol (NAAP) and performed with monitored anesthesia care (MAC). Patients and methods This was a single-blind, non-randomized controlled equivalence trial that enrolled adults from a national CRC screening program (CRCSP). Patients were blindly assigned to undergo either colonoscopy with NAAP or MAC. The main outcome measure was the ADR in CRCSP colonoscopies performed with NAAP. Results We included 315 patients per group. The median age was 59.76 ± 5.81 years; 40.5 % of patients were women. The cecal intubation rate was 97 %, 81.8 % of patients had adequate bowel preparation, withdrawal time was > 6 minutes in 98.7 %, and the median global exploration time was 24.25 ± 8.86 minutes (range, 8-70 minutes). The ADR was 62.9 % and the complication rate (CR) was 0.6 %. Analysis by intention-to-treat showed an ADR in the NAAP group of 64.13 % compared with 61.59 % in the MAC group, a difference (δADR) of 2.54 %, 95 %CI: -0.10 to 0.05. Analysis by per-protocol showed an ADR in the NAAP group of 62.98 %, compared with 61.94 % in the MAC group, δADR: 1.04 %, 95 %CI: -0.09 to 0.07. There was no difference in CR (NAAP: 0,63 vs. MAC: 0.63); P = 1.0. Conclusions ADR in colorectal cancer screening colonoscopies performed with NAAP was equivalent to that in those performed with MAC. Similarly, there was no difference in complication rates.

Abstract
INTRODUCTION This study investigated whether transcutaneous electrical acupuncture point stimulation (TEAS) at PC6 can reduce the proportion of elderly patients experiencing a drop of ⩾4% in peripheral capillary oxygen saturation (SpO2) while undergoing colonoscopy under sedation. METHODS A total of 32 elderly patients (aged ⩾ 65 years) scheduled for colonoscopy were randomly assigned in a 1:1 ratio to receive either real or sham TEAS (treatment or control groups, respectively). Each patient received oxygen (2 L/min) delivered routinely via nasal cannula. The treatment group was given TEAS at PC6 for 20 min at 2 Hz frequency and 6 mA intensity; the control group underwent the same procedures but with zero frequency/intensity. SpO2 and other physiological parameters were measured prior to sedation and colonoscopy (baseline) and at seven other timepoints through departure from recovery. Depth of anesthesia was measured using a Narcotrend monitor. RESULTS Significantly fewer patients in the treatment group experienced a ⩾4% decrease from baseline SpO2 (2/16) than patients in the control group (10/16; p = 0.004). The two groups were comparable with regard to respiratory rate, systolic and diastolic blood pressures, mean arterial pressure, and heart rate. CONCLUSION TEAS applied at PC6 with 2 Hz frequency was feasible and may be helpful in reducing the rate of hypoxia in elderly patients during colonoscopy.Trial registration number: NCT03775122 (ClinicalTrials.gov).

Abstract
OBJECTIVE Endoscopist-directed propofol (EDP) sedation is becoming more popular, with a reported safety and efficacy similar to anesthesiologist-administered propofol (AAP). The aim of this study is to compare the efficiency of EDP and AAP in patients of low-intermediate anesthetic risk. METHODS A prospective cost-effectiveness comparison study was conducted. The costs of the endoscopic procedures in the EDP and AAP group were calculated using the full cost methodology after breaking down the endoscopic activity into relative value units to allocate costs in an equitable way. To determine the effectiveness, adverse events related to endoscopic sedation and the number of incomplete procedures were registered for the EDP group and compared with those published by anesthesiologists for AAP. RESULTS A total of 1165 and 18 919 endoscopic procedures were, respectively, included in the EDP and AAP groups. The average costs of EDP vs. AAP for gastroscopy, colonoscopy and endoscopic ultrasound were &OV0556; 182.81 vs. &OV0556; 332.93, &OV0556; 297.07 vs. &OV0556; 459.76, and &OV0556; 319.92 vs. &OV0556; 485.12, respectively. No significant differences were detected regarding the rate of overall adverse events (4.43 vs. 4.46%) or serious adverse events (0 vs. 0.17%); the rate of arterial hypotension was significantly lower in the EDP group: 0.34 vs. 1.78% [odds ratio (OR), 0.19; 95% confidence interval (CI), 0.08-0.46] and the desaturation rate was significantly lower in the AAP group: 3.26 vs. 1.29% (OR, 2.58; 95% CI, 1.85-3.60). No significant differences were found in terms of incomplete examinations (0.17 vs. 0.14%). CONCLUSION In patients with low-intermediate anesthetic risk referred for an endoscopic examination, EDP appears to be more efficient than AAP.

Abstract
Background & Aims:
Sedation and analgesia are important elements of endoscopic
examinations; sedation for colonoscopy aims to relieve patient discomfort and anxiety, improve the
outcome of the examination, diminish the patient’s memory of the event and achieve comfortable
and technically successful endoscopic procedure.
Methods:
Our prospective study was carried out on 150 patients who were referred for colonoscopy;
they were divided into two groups based on the pre-endoscopic sedation given for them: propofol
fentanyl or propofol ketamine. Detailed histories, thorough physical examinations, and routine
laboratory investigations were performed for all patients, along with monitoring of their vital signs and
oxygen saturation levels (before, during and after colonoscopy), to assess safety, efficacy, recovery
times, complications of the sedative drugs, comfort of the patients and endoscopists.
Results:
There was no statistically significant difference between the two groups in terms of age,
sex and Body Mass Indexes (BMI). With respect to their Mean Arterial Blood Pressures (MAPs)
and heart rates, there was high hemodynamic stability in the propofol ketamine group, and both the
groups were efficacious, although the propofol fentanyl group had shorter recovery times than the
propofol ketamine group (3±1.7 minutes and 4±2.8 minutes, respectively). However, nausea, vomiting
and hypoxia were common in the propofol fentanyl group, while hallucinations were common
in the propofol ketamine group. In propofol fentanyl group; there was a significant decrease in the
heart rate more common in females (with age range 39-58 years) during and after colonoscopy
[p value 0.01].
Conclusion:
Sedation with propofol ketamine during colonoscopy was found to be safe and
efficacious to achieve hemodynamic stability with fewer complications than propofol fentanyl.

Abstract
The last few decades of gastrointestinal (GI) endoscopy have seen phenomenal growth. In many aspects, GI endoscopy has led the field of nonsurgical interventional medicine. In many aspects, this growth is facilitated by advancements in sedation-both drugs and techniques. Unfortunately, the topic of GI endoscopy sedation is also mired in many controversies, mainly emanating from the cost of anesthesia providers. While no one debates their role in the majority of advanced endoscopic procedures, the practice of universal propofol sedation in the USA, delivered by anesthesia providers, needs a closer look. In this review, medical, political, and economic considerations of this important topic are discussed in a very frank and honest way. While such ubiquitous propofol use has increased satisfaction of both patients and gastroenterologists, there is little justification. More importantly, going by the evidence, there is even less justification for the mandated anesthesia providers use for such delivery. Unfortunately, the FDA could not be convinced otherwise. The new drug fospropofol met the same fate. Approval of SEDASYS®, the first computer-assisted personalized sedation system, was a step in the right direction, nevertheless an insufficient step that failed to takeoff. As a result, in spite of years of research and efforts of many august societies, the logjam of balancing cost and justification of propofol sedation has continued. We hope that recent approval of remimazolam, a novel benzodiazepine, and potential approval of oliceridine, a novel short-acting opioid, might be able to contain the cost without compromising the quality of sedation.

Abstract
Background Endoscopist-directed balanced propofol sedation (BPS) appears to be safe and effective for routine endoscopy. However, there are limited data on its use in endoscopic retrograde cholangiopancreatography (ERCP). We evaluated the safety and efficacy of endoscopist-directed BPS for ERCP, and compared patient outcomes with anesthesiologist-administered moderate sedation. Methods This was a retrospective cohort study, using prospectively collected endoscopy data from a tertiary care medical center where endoscopist-directed BPS during ERCP is routine practice. Adverse outcomes included need for bag-mask ventilation or intubation, aborted ERCP due to sedation, hospital admission post-ERCP (outpatients)/change in the level of care (inpatients), and death within 24 h. Results A total of 501 patients underwent ERCP with the use of endoscopist-directed BPS: Cohort 1 - 380 (76%) inpatients, mean age 64.1, 46% male, 24% American Society of Anesthesiologists physical status (ASA) score I, 65% ASA II, 11% ASA III. Concurrently, 24 patients received anesthesiologist-administered moderate sedation: Cohort 2 - 19 (79%) inpatients, mean age 65.0, 67% male, 12% ASA I, 25% ASA II, 38% ASA III, 25% ASA IV. In Cohort 1, none of the adverse outcomes were observed. Propofol dose was inversely correlated with age (r=-0.42, P<0.001), ASA score (r=-0.19, P<0.001), and Mallampati score (r=-0.24, P<0.001). One patient in Cohort 2 who received anesthesiologist-administered BPS required bag-mask ventilation and the ERCP was prematurely aborted because of the sedation. There were no deaths from any cause within 24 h of ERCP. Conclusion Endoscopist-directed BPS appears safe, efficacious, and feasible for ASA I-III patients undergoing inpatient or ambulatory ERCP.

Abstract
The role of endoscopic retrograde cholangiopancreatography (ERCP) has dramatically changed in the last years, mainly into that of a therapeutic procedure. The treatment of benign biliary disease, like “difficult” choledocolithiasis, with endoscopic papillary large balloon dilation combined with endoscopic sphinterotomy has proven an effective and safe technique. Moreover, safety in ERCP has improved as well, with the prevention of post-ERCP pancreatitis and patient-to-patient transmission of infections. The advent of self-expandable metal stenting has radically changed the management of biliopancreatic malignant strictures, while the role for therapy of benign strictures is still controversial. In addition, cholangioscopy (though the direct visualization of the biliopancreatic ductal system) has allowed for characterization of indeterminate biliary strictures and facilitated rescue therapy of large biliary stones deemed removable. Encouraging data from tissue ablation techniques, such as photodynamic therapy and radiofrequency ablation, need to be confirmed by large sample size clinical controlled trials. On the other hand, we have no drug-coated stents yet available to implant and evidence for the use of biodegradable stents is still weak. The competency and privileging of ERCP and endoscopic ultrasonography have been analyzed longer but the switch between the two procedures, at the same time, is becoming ordinary; as such, the endoscopist interested in this field should undergo parallel edification through training plans. Finally, the American Society for Gastrointestinal Endoscopy’s statement on non-anesthesiologist administration of propofol for gastrointestinal endoscopy is not actually endorsed by the European Society of Anaesthesiology, having many medical-legal implications in some European countries.

Abstract
OBJECTIVES propofol is a rapid acting hypnotic that is becoming the drug of choice for sedation in digestive endoscopy worldwide. There is some controversy with regard to the use of propofol by physicians who are not anesthesiologists. We present our experience of the administration of propofol by endoscopist and nursing personnel. METHODS this was a retrospective study of sedation in endoscopy. Propofol was exclusively used and administered by the endoscopist who performed the procedure and the nursing staff. All patients included were of a low and moderate surgical risk (ASA I, II and III). No complementary medication was used such as benzodiazepines or opiates. RESULTS a total of 70,696 digestive endoscopy procedures performed between 2002 and 2017 were included in the study. Propofol was administered in an induction bolus of 10 to 50 mg, continuing with intermittent boluses of 10 to 20 mg, according to the patients' response. The incidence of complications was very low, assisted ventilation with a mask was required on 78 (0.11%) occasions. Only one case required endotracheal intubation and two patients had significant hypotension that required the administration of ephedrine. The average recovery time of all neuropsychomotor functions after the procedure was 15 minutes; 98% of patients reported a good or excellent level of tolerance and clearly remembered the details of the interview one hour after the procedure. CONCLUSIONS the use of propofol as a sedative in digestive endoscopy is a safe and effective technique, provided that it is administered and controlled by the endoscopist and nursing staff in properly selected patients. This allows gastroenterologists to achieve adequate sedation.

Abstract
BACKGROUND AND AIMS Remimazolam is an ultrashort-acting benzodiazepine. METHODS We performed a randomized double-blind comparison of remimazolam to placebo for outpatient colonoscopy. This study design was a requirement of the U.S. Food and Drug Administration. An additional group was randomized to open-label midazolam administered according to its package insert instructions (the randomization ratio for remimazolam:placebo:midazolam was 30:6:10). Study medications were administered under the supervision of the endoscopist, without any involvement of an anesthesia specialist. Patients were given 50 to 75 μg of fentanyl before receiving study medications. Patients who failed to achieve adequate sedation in any arm were rescued with midazolam dosed at the investigator's discretion. The primary endpoint was a composite that required 3 criteria be met: completion of the colonoscopy, no need for rescue medication, and ≤5 doses of remimazolam or placebo in any 15-minute interval (≤3 doses of midazolam in any 12-minute interval in the open-label midazolam arm). RESULTS There were 461 randomized patients in 12 U.S. sites. The primary endpoint was met for remimazolam, placebo, and midazolam in 91.3%, 1.7%, and 25.2% of patients, respectively (P < .0001 for remimazolam vs placebo). Patients administered remimazolam received less fentanyl, had faster recovery of neuropsychiatric function, were ready for discharge earlier, and felt back to normal sooner than patients with both placebo and midazolam. Hypotension was less frequent with remimazolam, and hypoxia occurred in 1% of patients with remimazolam or midazolam. There were no treatment-emergent serious adverse events. CONCLUSION Remimazolam can be administered safely under the supervision of endoscopists for outpatient colonoscopy, and it allows faster recovery of neuropsychiatric function compared with placebo (midazolam rescue) and midazolam.

Abstract
BACKGROUND AND AIMS Etomidate is a short-acting intravenous hypnotic with a safety profile that is superior to alternative drugs such as propofol. However, there is a lack of evidence on the safety of etomidate in ERCP. The objective of this study was to compare efficacy and safety profiles of etomidate and propofol for endoscopic sedation. METHODS This single-center, randomized, double-blind, noninferiority trial included patients with American Society of Anesthesiologists (ASA) physical status I to II who had been scheduled for ERCP. All patients received .05 mg/kg midazolam intravenously as pretreatment before receiving etomidate or propofol. Either etomidate or propofol was then administered according to group allocation. The primary endpoint was an overall respiratory event. A noninferiority margin of 10% was assumed. RESULTS Sixty-three and 64 patients were enrolled in the etomidate and propofol groups, respectively. Respiratory events were identified in 10 patients (15.6%) in the etomidate group and 16 patients (25.4%) on the propofol group, with a rate difference of -9.8% (1-sided 97.5% confidence interval, -∞ to 4.2%). The overall incidence of cardiovascular events tended to be higher in the etomidate group (67.2% vs 50.8%, P = .060). In particular, tachycardia (heart rate > 100 beats/min) was more common in the etomidate group than in the propofol group (64.1% vs 34.9%, P = .001). Transient hypotension tended to be less common in the etomidate group (6.3 vs 15.9%, P = .084). CONCLUSIONS Etomidate-based sedation during ERCP was noninferior to propofol-based sedation in terms of the overall incidence of respiratory events in patients with ASA physical status I to II.

Abstract
AIM To investigated characteristics, diagnosis, bowel-cleansing preparation, sedation, and colonoscope length and diameter in Japanese pediatric patients receiving total colonoscopy.
METHODS The present study evaluated consecutive patients aged ≤ 15 years who had undergone their first colonoscopy in Kurume University between January 2007 and February 2015. Data were retrospectively analyzed. We identified 110 pediatric patients who had undergone colonoscopy that had reached the cecum, allowing the observation of the total colon.
RESULTS Hematochezia, abdominal pain, and diarrhea were the most common symptoms. For bowel-cleansing preparation, pediatric patients aged ≤ 12 years were treated with magnesium citrate, and patients aged 13-15 years were treated with polyethylene glycol 4000. For sedation, thiamylal with pentazocine, which has an analgesic effect, was used in patients aged ≤ 6 years, and midazolam with pentazocine was used in patients aged ≥ 7 years. Regarding the choice of endoscope, short and thin endoscopes were selected for younger patients, particularly patients aged ≤ 3 years. Positive diagnoses were made in 78 patients (70.9%). Inflammatory bowel disease (n = 49, 44.5%), including ulcerative colitis (n = 37, 33.6%) and Crohn’s disease (n = 12, 10.9%), was the most common diagnosis.
CONCLUSION Colonoscopy offers a high diagnostic capability for pediatric patients with gastrointestinal symptoms. The selection of appropriate management the performance of colonoscopy is important in pediatric patients.

Abstract
PURPOSE The purpose of this study was to determine differences in sedation-related adverse events according to the type of provider monitoring and delivering sedation. DESIGN AND METHODS A retrospective, cross-sectional, correlational design using secondary data from the Pediatric Sedation Research Consortium database was used for this study. RESULTS A sample of 36,352 cases (0-14 years of age) sedated and monitored for diagnostic radiology procedures by three types of providers (registered nurses [RNs] alone, physicians (MDs) alone, or registered nurse + physician [RN+MD sedation teams]) were compared. Patients sedated by RNs alone or MDs alone had lower odds of unanticipated adverse events (odds ratios 0.46 and 0.53, respectively; p<0.0001) compared with RN+MD sedation provider teams. CONCLUSIONS Team skills may be an important competency for RN+MD sedation teams in the non-interventional radiology setting. PRACTICE IMPLICATIONS This study can inform clinicians, administrators, and quality-improvement managers of the differences in adverse event outcomes of pediatric radiology procedures when RN+MD teams provide sedation compared with RNs or MDs alone.

Abstract
OBJECTIVE To evaluate the effect of capnography monitoring on sedation-related adverse events during procedural sedation and analgesia (PSA) administered for ambulatory surgery relative to visual assessment and pulse oximetry alone. DESIGN AND SETTING Systematic literature review and random effects meta-analysis of randomised controlled trials (RCTs) reporting sedation-related adverse event incidence when adding capnography to visual assessment and pulse oximetry in patients undergoing PSA during ambulatory surgery in the hospital setting. Searches for eligible studies published between 1 January 1995 and 31 December 2016 (inclusive) were conducted in PubMed, the Cochrane Library and EMBASE without any language constraints. Searches were conducted in January 2017, screening and data extraction were conducted by two independent reviewers, and study quality was assessed using a modified Jadad scale. INTERVENTIONS Capnography monitoring relative to visual assessment and pulse oximetry alone. PRIMARY AND SECONDARY OUTCOME MEASURES Predefined endpoints of interest were desaturation/hypoxaemia (the primary endpoint), apnoea, aspiration, bradycardia, hypotension, premature procedure termination, respiratory failure, use of assisted/bag-mask ventilation and death during PSA. RESULTS The literature search identified 1006 unique articles, of which 13 were ultimately included in the meta-analysis. Addition of capnography to visual assessment and pulse oximetry was associated with a significant reduction in mild (risk ratio (RR) 0.77, 95% CI 0.67 to 0.89) and severe (RR 0.59, 95% CI 0.43 to 0.81) desaturation, as well as in the use of assisted ventilation (OR 0.47, 95% CI 0.23 to 0.95). No significant differences in other endpoints were identified. CONCLUSIONS Meta-analysis of 13 RCTs published between 2006 and 2016 showed a reduction in respiratory compromise (from respiratory insufficiency to failure) during PSA with the inclusion of capnography monitoring. In particular, use of capnography was associated with less mild and severe oxygen desaturation, which may have helped to avoid the need for assisted ventilation.

Abstract
The Society for Gastroenterology Nurses and Associates (SGNA) launched a nurse fellowship program in 2011 to promote evidence-based practice. Each accepted applicant was challenged to select a relevant topic, explore the current research, and translate this information to daily practice. The author, an SGNA Fellow, selected the topic, nurse-administered propofol sedation, that has been a prevailing subject in endoscopy for many years. A significant amount of literature has been written on the drug's safety and efficacy. This article explores a brief history of the practice and the future of this controversial drug for procedural sedation. A review of current literature is explored with an emphasis on the past 5 years as well as a discussion on regulatory limitations that have been placed on the practice of non-anesthesiologist-administered propofol sedation.

Abstract
Gastrointestinal endoscopic sedation has improved procedural and patient outcomes but is associated with attendant risks of oversedation and hemodynamic compromise. Therefore, close monitoring during endoscopic procedures using sedation is critical. This monitoring begins with appropriate staff trained in visual assessment of patients and analysis of basic physiologic parameters. It also mandates an array of devices widely used in practice to evaluate hemodynamics, oxygenation, ventilation, and depth of sedation. The authors review the evidence behind monitoring practices and current society recommendations and discuss forthcoming technologies and techniques that are poised to improve noninvasive monitoring of patients under endoscopic sedation.

Abstract
Endoscopist-directed propofol (EDP) refers to delivery of propofol for endoscopic sedation under the direction of an endoscopist without any involvement of an anesthesia specialist (anesthesiologist or nurse anesthetist). EDP has been proven to be safe and is also cost-effective compared with the anesthetist delivered sedation for endoscopy. EDP has been endorsed by US gastroenterology societies as an appropriate paradigm for clinical practice. EDP has proliferated in Switzerland and Germany, but its expansion in the United States has been limited by financial disincentives, concerns about medical-legal risk for endoscopists, and regulatory obstacles.

Abstract
The term, non-operating room anesthesia, describes a location remote from the main operating suites and closer to the patient, including areas that offer specialized procedures, like endoscopy suites, cardiac catheterization laboratories, bronchoscopy suites, and invasive radiology suites. There has been an exponential growth in such procedures and they present challenges in both organizational aspects and administration of anesthesia. This article explores the requirements for the location, preoperative evaluation and patient selection, monitoring, anesthesia technique, and postoperative management at these sites. There is a need to better define the role of the anesthesia personnel at these remote sites.

Abstract
OBJECTIVE Different regimens are used for sedation during endoscopic retrograde cholangiopancreatography (ERCP). Our objectives were to compare safety, ease of treatment, recovery, and patients' experiences using patient-controlled sedation (PCS) with propofol, nurse anesthetist-controlled sedation (ACS), or the department's standard of care, midazolam given by the procedure team (control group). MATERIAL AND METHODS The study included 281 adults in 301 procedures. The PCS group (n = 101) delivered bolus doses of 5 mg of propofol according to their need for sedation. The ACS group (n = 100) had 2-8 mg/kg/h of propofol infused, with the target for sedation being level 3 of the Observer's Assessment of Alertness/Sedation (OAA/S) scale. The control group was given 2-3 mg of midazolam for induction and additional 1 mg if required. RESULTS PCS and ACS increased the ease of the procedure and reduced the number of sedation failures compared to midazolam sedation (ACS n = 0; PCS n = 4; midazolam n = 20). The ACS group had more deeply sedated patients (OAA/S level 2), desaturation, and obstructed airways than the PCS and midazolam groups. Time to full recovery (Aldrete score ≥9) was shortest following PCS. PCS resulted in the least fatigue and pain after the procedure. Patients' preference for PCS and ACS was the same. CONCLUSION PCS with propofol is superior to midazolam and comparable to ACS. PCS resulted in a rapid recovery, fewer respiratory events, and was almost as effective as ACS in ensuring a successful examination.

Abstract
Fee-for-service payments encourage high-volume services rather than high-quality care. Alternative payment models (APMs) aim to realign financing to support high-value services. The 2 main components of gastroenterologic care, procedures and chronic care management, call for a range of APMs. The first step for gastroenterologists is to identify the most important conditions and opportunities to improve care and reduce waste that do not require financial support. We describe examples of delivery reforms and emerging APMs to accomplish these care improvements. A bundled payment for an episode of care, in which a provider is given a lump sum payment to cover the cost of services provided during the defined episode, can support better care for a discrete procedure such as a colonoscopy. Improved management of chronic conditions can be supported through a per-member, per-month (PMPM) payment to offer extended services and care coordination. For complex chronic conditions such as inflammatory bowel disease, in which the gastroenterologist is the principal care coordinator, the PMPM payment could be given to a gastroenterology medical home. For conditions in which the gastroenterologist acts primarily as a consultant for primary care, such as noncomplex gastroesophageal reflux or hepatitis C, a PMPM payment can support effective care coordination in a medical neighborhood delivery model. Each APM can be supplemented with a shared savings component. Gastroenterologists must engage with and be early leaders of these redesign discussions to be prepared for a time when APMs may be more prevalent and no longer voluntary.

Abstract
BACKGROUND AND AIMS The aim of the study was to evaluate the safety of non-anesthesia provider (NAAP)-administered propofol sedation for advanced endoscopic procedures with those of anesthesia provider (AAP). METHODS PubMed, EMBASE, Cochrane Central Register of Controlled Trials, Scopus, and Web of Science databases were searched for prospective observational trials involving advanced endoscopic procedures. From a total of 519 publications, 26 were identified to meet inclusion criteria (10 AAPs and 16 NAAPs) and were analyzed. Data were analyzed for hypoxia rate, airway intervention rates, endoscopist, and patient satisfaction scores and total propofol administered. RESULTS Total number of procedures in NAAP and AAP groups was 3018 and 2374, respectively. Pooled hypoxia (oxygen saturation less than 90 %) rates were 0.133 (95 % CI 0.117-0.152) and 0.143 (95 % CI 0.128-0.159) in NAAP and AAP, respectively. Similarly, pooled airway intervention rates were 0.035 (95 % CI 0.026-0.047) and 0.133 (95 % CI 0.118-0.150), respectively. Pooled patient satisfaction rate, pooled endoscopist satisfaction rate, and mean propofol administered dose for NAAP were 7.22 (95 % CI 7.17-7.27), 6.03 (95 % CI 5.94-6.11), and 251.44 mg (95 % CI 244.39-258.49) in that order compared with 9.82 (95 % CI 9.76-9.88), 9.06 (95 % CI 8.91-9.21), and 340.32 mg (95 % CI 327.30-353.33) for AAP. CONCLUSIONS The safety of NAAP sedation compared favorably with AAP sedation in patients undergoing advanced endoscopic procedures. However, it came at the cost of decreased patient and endoscopist satisfaction.

Abstract
The use of propofol for sedation during endoscopy has been increasing, particularly given its association with superior patient satisfaction. Propofol sedation may also allow for higher quality endoscopy exams, increased efficiency of endoscopy suites and most particularly, permit better patient compliance with colonoscopy for colorectal cancer screening. However, propofol is typically provided by anesthesia specialists via monitored anesthesia care, and is associated with significant economic burden. Given the increasing use of monitored anesthesia care, which adds significant costs to endoscopy, payers are likely to react with changes in payer policies. One alternative to monitored anesthesia care is non-anesthesiologist administered propofol, which due to safety concerns and a lack of reimbursement has not been widely adopted in the US.

Abstract
BACKGROUND Although endoscopic submucosal dissection (ESD) is routinely performed under sedation, the difference in ESD performance according to sedation method is not well known. This study attempted to prospectively assess and compare the satisfaction of the endoscopists and patient stability during ESD between two sedation methods. METHODS One hundred and fifty-four adult patients scheduled for ESD were sedated by either the IMIE (intermittent midazolam/propofol injection by endoscopist) or CPIA (continuous propofol infusion by anesthesiologist) method. The primary endpoint of this study was to compare the level of satisfaction of the endoscopists between the two groups. The secondary endpoints included level of satisfaction of the patients, patient's pain scores, events interfering with the procedure, incidence of unintended deep sedation, hemodynamic and respiratory events, and ESD outcomes and complications. RESULTS Level of satisfaction of the endoscopists was significantly higher in the CPIA Group compared to the IMIE group (IMIE vs. CPIA; high satisfaction score; 63.2% vs. 87.2%, P=0.001). The incidence of unintended deep sedation was significantly higher in the IMIE Group compared to the CPIA Group (IMIE vs. CPIA; 17.1% vs. 5.1%, P=0.018) as well as the number of patients showing spontaneous movement or those requiring physical restraint (IMIE vs. CPIA; spontaneous movement; 60.5% vs. 42.3%, P=0.024, physical restraint; 27.6% vs. 10.3%, P=0.006, respectively). In contrast, level of satisfaction of the patients were found to be significantly higher in the IMIE Group (IMIE vs. CPIA; high satisfaction score; 85.5% vs. 67.9%, P=0.027). Pain scores of the patients, hemodynamic and respiratory events, and ESD outcomes and complications were not different between the two groups. CONCLUSION Continuous propofol and remifentanil infusion by an anesthesiologist during ESD can increase the satisfaction levels of the endoscopists by providing a more stable state of sedation.

Abstract
BACKGROUND Sedation practices for pediatric gastrointestinal endoscopic procedures (PGEP) vary based on infrastructure, availability of trained personnel, and local protocols. Data on prevalent sedation practices is lacking from India. This study aimed to survey the sedation practices for PGEP in India. METHODS A mailing list was constituted with the e-mail addresses of the members of the Indian Society of Pediatric Gastroenterology, Hepatology and Nutrition, Indian Academy of Pediatrics, Association of Surgeons of India, Indian Association of Pediatric Surgeons, and Indian Society of Gastroenterology. The web-based survey was sent by e-mail. RESULTS Of the 498 recipients, who responded through the survey link, 91 did not complete the survey. Among those who completed the survey, 91 performed PGEP. Among these 91, 12.1 % performed PGEP without sedation or general anesthesia. Anesthetist involvement was associated with use of propofol based-sedation. Of the respondents, 70.3 % found non-anesthetist administered propofol sedation unacceptable while 38.5 % of the centers had a policy against it. Two-thirds of the respondents were assisted by an anesthetist for most PGEP. An operating room (OR) was used for PGEPs by 23.1 %. PGEP in a non-teaching hospital, non-availability of pediatrician in the endoscopy room, use of an OR for PGEP, and the easy availability of an anesthetist were strongly associated with the involvement of an anesthetist. CONCLUSIONS The survey indicates a high frequency of involvement of anesthetists and use of OR. This survey should serve as an impetus to evaluate the cost of PGEP in India and the training accorded to non-anesthetists for procedural sedation.

Abstract
INTRODUCTION Adequate sedation is one of the cornerstones of good quality gastrointestinal endoscopy (GIE). Propofol sedation has increased significantly but there has been much debate over whether it can be administered by endoscopists. The aim of this prospective trial was to compare nonanesthesiologist-administered propofol (NAAP) and monitored anesthesia care (MAC). METHODS A total of 2000 outpatients undergoing GIE at Hospital Albert Einstein (São Paulo, Brazil), a tertiary-care private hospital, were divided into two matched groups: NAAP (n = 1000) and MAC (n = 1000). In NAAP, propofol doses were determined by the endoscopist. A second physician stayed in the room during the entire procedure, according to local regulations. In MAC, the anesthesiologist administered propofol. RESULTS In total, 1427 patients (71.3 %) were ASA (American Society of Anesthesiologists) class I and 573 were ASA class II. In NAAP, patients received more propofol + fentanyl (61.1 % vs. 50.5 %; P < 0.05) and there were fewer cases of deep sedation (44.7 % vs. 66.1 %; P < 0.05). Hypoxemia rates were similar (12.8 % for NAAP and 11.2 % for MAC; P = 0.3) but these reverted more rapidly in MAC (4.22 seconds vs. 7.26 seconds; P < 0.05). Agitation was more frequent in MAC (14.0 % vs. 5.6 %; P < 0.05). No later complications were observed. Patient satisfaction was very high and similar in both groups. CONCLUSION In this setting, NAAP was as safe and effective as MAC for healthy patients undergoing GIE. Clinical trial ref. no.: U1111-1134-4430.

Abstract
Compared to standard endoscopy, endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound (EUS) are often lengthier and more complex, thus requiring higher doses of sedatives for patient comfort and compliance. The aim of this review is to provide the reader with information regarding the use, safety profile, and merits of propofol for sedation in advanced endoscopic procedures like ERCP and EUS, based on the current literature.

Abstract
Sedation allows patients to tolerate unpleasant endoscopic procedures by relieving anxiety, discomfort, or pain. It also reduces a patient's risk of physical injury during endoscopic procedures, while providing the endoscopist with an adequate setting for a detailed examination. Sedation is therefore considered by many endoscopists to be an essential component of gastrointestinal endoscopy. Endoscopic sedation by nonanesthesiologists is a worldwide practice and has been proven effective and safe. Moderate sedation/analgesia is generally accepted as an appropriate target for sedation by nonanesthesiologists. This focused review describes the general principles of endoscopic sedation, the detailed pharmacology of sedatives and analgesics (focused on midazolam, propofol, meperidine, and fentanyl), and the multiple regimens available for use in actual practice.

Abstract
BACKGROUND AND STUDY AIMS Propofol is increasingly being used for sedation purposes during endoscopic retrograde cholangiopancreatography (ERCP). This study aimed to evaluate the safety of non-anaesthesiologist administration of propofol (NAAP) during therapeutic ERCP. PATIENTS AND METHODS Patients, who underwent ERCP at Centre for Liver and Digestive Diseases, Holy Family Hospital, Rawalpindi, were included in the study. Propofol sedation was administered by a physician who was a non-anaesthesiologist certified in basic and advanced cardiac life support. The total study duration was 6 months. The primary outcome variable was the frequency of any sedation-related complication. RESULTS A total of 156 patients (41% males and 59% females) were enrolled in the study. The mean propofol dose used during the procedure was 201±132 mg. The mean propofol dose, when adjusted to weight and duration of procedure, was 0.05±0.04 mg kg(-1)min(-1). According to the American Society of Anesthesiologists (ASA) classification, 136 (87%) patients were placed in ASA class I and II and 20 (13%) patients were of ASA class III. Only two patients developed sedation-related complication: one minor requiring bag-mask ventilation and other major requiring mechanical ventilation via endotracheal intubation. Both were managed by the trained non-anaesthesiologist and gastroenterologist at the place of procedure. No patients required cardiopulmonary resuscitation and admission to the intensive care unit. There were no sedation-related deaths. CONCLUSION NAAP sedation can be considered safe for low-risk patients (ASA class I and II) undergoing ERCP. The presence of a trained anaesthetist is advisable in high-risk patients (ASA class III and higher) with significant co-morbidities.

Abstract
BACKGROUND AND AIMS Appropriate use of propofol is necessary, and objective monitoring of sedation with propofol may be helpful. Studies on the efficacy of bispectral index (BIS) monitoring in deep sedation have been conducted, but its efficacy in colonoscopy with moderate sedation is unknown. In this study, the efficacy of BIS monitoring during colonoscopy with moderate level sedation via balanced propofol sedation was investigated. METHODS To determine the cut-off value of BIS before the test, an optimal BIS value was determined. Patients who were scheduled to undergo outpatient colonoscopy were prospectively randomized to either a BIS or control group. Finally, a total of 115 patients were selected for this study. The satisfaction level, the complication, and the dosage of the administered propofol were compared. RESULTS The BIS values and the modified observer's assessment of alertness/sedation scores (MOAA/S) were positively correlated (r=0.66 and p<0.001). The optimal cut-off value of BIS for maintaining moderate sedation was 81, and the area under the ROC curve was 0.88 (95% CI 0.82-0.93), indicating high prediction accuracy. However, there was no difference between the BIS group and the control group in levels of satisfaction of either patients or endoscopists. In addition, there was no difference in the complication and the required dose of propofol between both groups. CONCLUSIONS BIS and clinical sedation scores, MOAA/S scores, showed a high level of correlation. However, no significant efficacy was observed in the BIS group who underwent outpatient colonoscopy.

Abstract
AIM To compare deep sedation with propofol-fentanyl and midazolam-fentanyl regimens during upper gastrointestinal endoscopy. METHODS After obtaining approval of the research ethics committee and informed consent, 200 patients were evaluated and referred for upper gastrointestinal endoscopy. Patients were randomized to receive propofol-fentanyl or midazolam-fentanyl (n = 100/group). We assessed the level of sedation using the observer's assessment of alertness/sedation (OAA/S) score and bispectral index (BIS). We evaluated patient and physician satisfaction, as well as the recovery time and complication rates. The statistical analysis was performed using SPSS statistical software and included the Mann-Whitney test, χ² test, measurement of analysis of variance, and the κ statistic. RESULTS The times to induction of sedation, recovery, and discharge were shorter in the propofol-fentanyl group than the midazolam-fentanyl group. According to the OAA/S score, deep sedation events occurred in 25% of the propofol-fentanyl group and 11% of the midazolam-fentanyl group (P = 0.014). Additionally, deep sedation events occurred in 19% of the propofol-fentanyl group and 7% of the midazolam-fentanyl group according to the BIS scale (P = 0.039). There was good concordance between the OAA/S score and BIS for both groups (κ = 0.71 and κ = 0.63, respectively). Oxygen supplementation was required in 42% of the propofol-fentanyl group and 26% of the midazolam-fentanyl group (P = 0.025). The mean time to recovery was 28.82 and 44.13 min in the propofol-fentanyl and midazolam-fentanyl groups, respectively (P < 0.001). There were no severe complications in either group. Although patients were equally satisfied with both drug combinations, physicians were more satisfied with the propofol-fentanyl combination. CONCLUSION Deep sedation occurred with propofol-fentanyl and midazolam-fentanyl, but was more frequent in the former. Recovery was faster in the propofol-fentanyl group.

Abstract
OBJECTIVE Target-controlled infusion (TCI) of propofol is an effective way of delivering propofol during endoscopy. However, the ideal effect-site concentration (Ce) of propofol has not yet been defined in an Asian population. This study aimed to determine the ideal Ce of propofol in painless gastrointestinal endoscopy in a Taiwanese population. METHODS A total of 121 consecutive patients undergoing diagnostic endoscopy were recruited for this study. The endoscopic procedure was carried out within 1 h. TCI of propofol was utilized during the procedure. All patients received the same regimen to induce conscious sedation, including a bolus of midazolam (0.04 mg/kg) and fentanyl (0.5 μg/kg). The Ce of propofol was calculated using the Schneider model. Patients were randomly assigned to either the low Ce group (1.5-2.5 μg/mL) or high Ce group (3.0-4.0 μg/mL). Their cardiovascular and respiratory events were monitored during the procedure and the patients' post-procedure satisfaction was evaluated. RESULTS The mean requirement for propofol was 232.02 mg in the low Ce group and 329.56 mg in the high Ce group, respectively (P < 0.0001). No unexpected event was observed in either group. However, more episodes of hypotension were observed in the high Ce group (P = 0.026). The post-procedure satisfaction rate between the two groups was comparable. CONCLUSION A low Ce of propofol TCI (1.5-2.5 μg/mL) achieved adequate anesthesia, reduced the risk of hypotension, and attained a high satisfaction rate in a Taiwanese population undergoing diagnostic painless endoscopy.
