High efficacy with deep nurse-administered propofol sedation for advanced gastroenterologic endoscopic procedures

A plea for a unified approach to sedation in gastrointestinal endoscopy in Romania: results from a prospective multicentric trial

Background. Adequate sedation is a prerequisite for quality endoscopic examination of the digestive tract. We aimed to evaluate the current practices and safety profile of sedation for gastrointestinal endoscopy in Romania and its impact on the technical success of the procedure and procedure-related adverse events.

Methods. We conducted a prospective, multicentric, observational study including all patients undergoing digestive endoscopic procedures under various degrees of sedation. We collected data regarding the endoscopic procedure, type and degree of sedation, drug regimens, personnel in charge of sedation, and relevant patient related information. The main study outcome was the rate of sedation-related adverse events; secondary study outcomes included procedure-related adverse events and the impact of sedation on procedure success.

Results. 1,043 consecutive endoscopic procedures from eight Romanian endoscopy units were included in our study. Sedation regimens were highly variable between participating centers, with 566 (54%) of procedures being performed under sedation provided by an anaesthesiologist. Sedation-related adverse events occurred in 40 cases (3.8%), most of them were mild respiratory and cardiovascular events and all reversed spontaneously.

On multivariate analysis, male gender, procedure type (endoscopic ultrasound and endoscopic retrograde cholangiopancreatography) and deep sedation were risk factors for complications. The endoscopy unit, ASA status, age and type of sedative did not influence the complication rate.

Conclusion. In conclusion, sedation for endoscopic procedures is generally safe, despite a high variability in sedation practices between centers in Romania. Establishing a national guideline on sedation for gastrointestinal endoscopy will ensure consistent and safe practice for these procedures.

Standard reporting elements for the performance of EUS: Recommendations from the FOCUS working group

Background and Objectives

Quality indicators for the performance of EUS have been developed to monitor and improve service value and patient outcomes. To support the incorporation of these indicators and standardize EUS documentation, we propose standard EUS reporting elements for endosonographers and endoscopy units.

Methods

A comprehensive literature search and review was performed to identify EUS quality indicators and key components of high-quality standardized EUS reporting. Guidance statements regarding standard EUS reporting elements were developed and reviewed at the Forum for Canadian Endoscopic Ultrasound (FOCUS) 2019 Annual Meeting.

Results

EUS reporting elements can be divided into preprocedural, intraprocedural, and postprocedural items. Preprocedural components include the type, indication, and urgency of the procedure and patient clinical information and consent. Intraprocedural components include the adequacy and extent of examination, relevant landmarks, lesion characteristics, sampling method, specimen quality, and intraprocedural adverse events. Postprocedural components include a summary and synthesis of relevant findings as well as recommended management and follow-up.

Conclusions

Standardizing reporting elements may help improve the care of patients undergoing EUS procedures. Our review provides a practical guide and compilation of recommended reporting elements to ensure ongoing best practices and quality improvement in EUS.

Efficacy and Safety of Non-Anesthesiologist Administration of Propofol Sedation in Endoscopic Ultrasound: A Propensity Score Analysis

In spite of promising preliminary results, evidence supporting the use of non-anesthesiologist-administered propofol sedation (NAAP) in endoscopic ultrasound (EUS) procedures is still limited. The aim of this manuscript was to examine the safety and efficacy of NAAP as compared to anesthesiologist-administered propofol sedation in EUS procedures performed in a referral center. Out of 832 patients referred to our center between 2016 and 2019, after propensity score matching two groups were compared: 305 treated with NAAP and 305 controls who underwent anesthesiologist-administered propofol sedation. The primary outcome was the rate of major complications. The median age was 67 years and the proportion of patients with comorbidities was 31.8% in both groups. One patient in each group (0.3%) experienced a major complication, whereas minor complications were observed in 13 patients in the NAAP group (4.2%) and 10 patients in the control group (3.2%; p = 0.52). Overall pain during the procedure was 2.3 ± 1 in group 1 and 1.8 ± 1 in group 2 (p = 0.67), whereas pain/discomfort upon awakening was rated as 1 ± 0.5 in both groups (p = 0.72). NAAP is safe and effective even in advanced EUS procedures. Further randomized-controlled trials (RCTs) are warranted to confirm these findings.

Periprocedural Role of Nurses During Interventional Endoscopic Procedures Under Deep Sedation

Background. Most of endoscopic procedures, either diagnostic or therapeutic, are nowadays performed under sedation, used as a standard practice in most of the centers. Consequently, the number and complexity of endoscopic procedures has increased as sedation diminishes anxiety and discomfort for patients, also improving the quality of endoscopic examinations, and outcomes in therapeutic endoscopy. Compared to standard diagnostic upper or lower GI endoscopy, endoscopic ultrasound (EUS) and endoscopic retrograde cholangiopancreatography (ERCP) are often longer and more complicated procedures, thus requiring higher doses of sedatives. Sedation levels and medication types depend on a variety of factors, related both to patient characteristics (age, comorbidities, preference, etc.), and procedure types (simple diagnostic endoscopy or more complex therapeutic procedures). Propofol has become undoubtedly the induction agent of choice as it is easy to administer, enables prompt awakening, and has fewer side effects. Aim. The aim of this paper is to outline the role and efficacy of the endoscopy nurse in the peri-procedural care of patients undergoing complex therapeutic interventions (EUS-guided and/or ERCP) under propofol sedation. Methods. At our institution, the Research Centre of Gastroenterology and Hepatology Craiova, 192 patients underwent interventional endoscopic procedures between January 2014-December 2014 (130 EUS and 62 ERCP) under sedation with propofol. We included 110 patients in our study that were followed-up between 4 to 6 hours after the procedures. The GI nurse was responsible that the patients and/or their accompanying persons receive proper information in both written and spoken form regarding their procedure and potential adverse events after sedation. After the procedures the side effects related to anesthesia were marked down by the GI nurse based on a standard questionnaire. Results. The patients mean age was 53.5 years old, with 46 (41.8%) women and 64 (58.2%) men. Most of the patients, that is 90 (81.8%), presented no adverse events. The other 20 patients (18.2%) had the following side effects from sedation: drowsiness in 5 (4.5%) of the cases, nausea in 3 cases (2.8%), vomiting in one case (0.9%), 2 (1.8%) of the patients presented dizziness, 2 (1.8%) headache, 3 (2.8%) coughing, only one patient (0.9%) had an injection site reaction, one (0.9%) had shivers, and 2 patients (1.8%) presented bradycardia. Patients that had side effects were mainly of advanced age and with associated diseases which included chronic kidney disease, cardio-vascular diseases. The nurse responsible with the follow-up of patients was able to rapidly assess their complaints and intervene to the benefit of the patient, before serious adverse events could occur. Conclusions. Although propofol sedations is generally considered safe, potential side effects should be held in mind. The GI nurse has a valuable role in monitoring patients and assessing their response to sedation after the procedure, as well as in timely stepping in where necessary to prevent further complications.

How to measure quality in endoscopic ultrasound

Quality is a key focus for gastrointestinal endoscopy and main international gastroenterology societies instituted specific task forces focused on this issue. Endoscopic ultrasound (EUS) represents one of the most fascinating fields to explore in gastrointestinal endoscopy due to its relatively limited availability out of high-volume centers. This leads to a particular need to define widely accepted quality indicators (QIs) and the ways to measure them. The current manuscript reviews these indicators in light of their impact on common clinical practice.

Paradigm shift: should the elderly undergo propofol sedation for DBE? A prospective cohort study

OBJECTIVE

Evaluate the safety of propofol-assisted double balloon enteroscopy (DBE) in elderly patients against a younger cohort.

DESIGN

Prospective cohort study.

SETTING

All patients undergoing DBE over a 30-month period were recruited at our tertiary centre.

PATIENTS

215 procedures in 161 patients were performed. An age cut-off of 65 years and above was used to define those who were elderly.

INTERVENTIONS

Patients were subcategorised into four groups: elderly or young undergoing DBE with propofol or conventional sedation (with midazolam±fentanyl).

MAIN OUTCOME MEASURES

Patient demographics, comorbidities, procedural data, complications, diagnostic and therapeutic yield were compared.

RESULTS

Cardiovascular disease and a higher American Society of Anaethesiologists (ASA) status were more prevalent in elderly patients undergoing DBE with propofol (p<0.05). Common indications for DBE were occult and overt obscure gastrointestinal bleeding and suspected Crohn's disease (elderly vs young: 50.7% vs 42.3%, 17.8% vs 12% and 19.2% vs 26.1%, respectively). Diagnostic yield was higher in elderly compared with young patients (75.3% vs 58.5%, p=0.016). The most common findings in elderly and young patients were angioectasia (30.1% and. 18.3%, respectively) and ulcers (17.8% and 9.2%, respectively), while therapeutic intervention rates were comparable (42.5% vs 32.4%, p=0.18). ASA status did not affect propofol dose (p=0.55) or procedure duration (p=0.31). Tolerance scores were favourable in those receiving propofol compared with conventional sedation (p<0.05). There was no difference in complications between the four groups (p=0.17).

CONCLUSION

Compared with young patients, propofol-assisted DBE in the elderly is safe and has a high diagnostic yield.

Enhancing the current evidence on endoscopist-directed propofol-based sedation

During the last years, there is more and more scientific evidence about the safety and feasibility of non-anesthesiologist administration of propofol (NAAP) in gastrointestinal endoscopy, reducing sedation induction and recovery time as well as increasing patient and endoscopist satisfaction. Furthermore, a similar risk of adverse events compared with traditional agents or anesthesiologist administration of propofol (AAP) has been described. The present special issue of the Spanish Journal of Gastroenterology (Revista Española de Enfermedades Digestivas) focusses on NAAP in different settings, including complex endoscopic procedures.

Sedation for advanced procedures in the bronchoscopy suite: proceduralist or anesthesiologist?

PURPOSE OF REVIEW

This article focuses on the issue of sedation provided either by proceduralists or anesthesiologists for advanced bronchoscopy procedures. The relative merits of both approaches are presented. Current evidence from the literature and guideline recommendations relevant to this topic are reviewed.

RECENT FINDINGS

In general, patient and proceduralist satisfaction as well as patient safety are increased when intravenous sedation is provided for advanced bronchoscopic procedures. However, guidelines by various societies remain vague on defining the appropriate level of care required when providing sedation for these procedures. In addition, targeted depth of sedation varies considerably among practitioners. While in some settings, nonanesthesiologist-administered propofol sedation has been proven safe; nevertheless, its use is controversial, especially in the bronchoscopy suite.

SUMMARY

The role of the anesthesiologist in sedation for advanced bronchoscopy remains undefined. When deep sedation for prolonged interventional procedures is needed or when dealing with patients who have multiple comorbidities, an anesthesiologist should be involved.
