Sedation for pediatric GI endoscopy

Pediatric Endoscopy Quality Improvement Network Quality Standards and Indicators for Pediatric Endoscopic Procedures: A Joint NASPGHAN/ESPGHAN Guideline

INTRODUCTION

High-quality pediatric gastrointestinal procedures are performed when clinically indicated and defined by their successful performance by skilled providers in a safe, comfortable, child-oriented, and expeditious manner. The process of pediatric endoscopy begins when a plan to perform the procedure is first made and ends when all appropriate patient follow-up has occurred. Procedure-related standards and indicators developed to date for endoscopy in adults emphasize cancer screening and are thus unsuitable for pediatric medicine.

METHODS

With support from the North American and European Societies of Pediatric Gastroenterology Hepatology and Nutrition (NASPGHAN and ESPGHAN), an international working group of the Pediatric Endoscopy Quality Improvement Network (PEnQuIN) used the methodological strategy of the Appraisal of Guidelines for REsearch and Evaluation (AGREE) II instrument to develop standards and indicators relevant for assessing the quality of endoscopic procedures. Consensus was sought via an iterative online Delphi process and finalized at an in-person conference. The quality of evidence and strength of recommendations were rated according to the GRADE (Grading of Recommendation Assessment, Development, and Evaluation) approach.

RESULTS

The PEnQuIN working group achieved consensus on 14 standards for pediatric endoscopic procedures, as well as 30 indicators that can be used to identify high-quality procedures. These were subcategorized into three subdomains: Preprocedural (3 standards, 7 indicators), Intraprocedural (8 standards, 18 indicators), and Postprocedural (3 standards, 5 indicators). A minimum target for the key indicator, "rate of adequate bowel preparation," was set at ≥80%.

DISCUSSION

It is recommended that all facilities and individual providers performing pediatric endoscopy worldwide initiate and engage with the procedure-related standards and indicators developed by PEnQuIN to identify gaps in quality and drive improvement.

Dexamethasone Reduces Postoperative Nausea in Pediatric Upper Endoscopy With Deep Sedation: A Randomized Controlled Trial

OBJECTIVES

We aimed to evaluate the effect of a single dose of preoperative dexamethasone on postoperative nausea and vomiting (PONV), a frequent complication and a major cause of delayed recovery in pediatric upper gastrointestinal endoscopy (UGIE) under sedation.

METHODS

In this double-blind randomized controlled study, 98 children aged 2 to 14, with American Society of Anesthesiologists status I to II, and undergoing elective UGIE with deep sedation were included and randomly assigned to 2 groups. Preoperatively, after anesthesia induction with sodium thiopental and maintenance with sevoflurane, patients in the intervention (n = 49) and control (n = 49) groups, respectively received 0.1 mg/kg i.v. dexamethasone and 2 cm i.v. 0.9% saline. Postoperatively, PONV incidence was measured as the primary outcome.

RESULTS

PONV incidence was significantly less in dexamethasone group (8.2%) compared to the control group (26.5%) (difference = 18.3%, 95% confidence interval: 3.4%-33%, P = 0.016). For secondary outcomes, between-group differences were not statistically significant: incidence of bronchospasm or laryngospasm (both 4.1%, P = 1); emergence delirium assessed with Pediatric Anesthesia Emergence Delirium scale (5.9 ± 3.4 vs 5.7 ± 3.2, P = 0.751); Modified Aldrete score at 0 minutes (9.4 ± 0.8 vs 9.3 ± 0.9, P = 0.909) and at 5 minutes (9.5 ± 0.7 vs 9.4 ± 0.9, P = 0.527); and recovery time (21.1 ± 6.6 vs 23.4 ± 8.6 minutes, P = 0.130).

CONCLUSIONS

A single preoperative dose of i.v. dexamethasone reduces PONV in children undergoing elective UGIE with deep sedation, but has no significant effect on the patient recovery time or the incidence of postoperative bronchospasm or laryngospasm and emergence delirium.

The impact of Narcotrend™ EEG-guided propofol administration on the speed of recovery from pediatric procedural sedation-A randomized controlled trial

BACKGROUND

Propofol is often used for procedural sedation in children undergoing gastrointestinal endoscopy. Reliable assessment of the depth of hypnosis during the endoscopic procedure is challenging. Processed electroencephalography using the Narcotrend Index can help titrating propofol to a predefined sedation level.

AIMS

The aim of this trial was to investigate the impact of Narcotrend Index-guided titration of propofol delivery on the speed of recovery.

METHODS

Children, aged 12-17 years, undergoing gastrointestinal endoscopy under procedural sedation, had propofol delivered via target controlled infusion either based on Narcotrend Index guidance (group NI) or standard clinical parameters (group C). Sedation was augmented with remifentanil in both study groups. The primary endpoint of this study was to compare the speed of fulfilling discharge criteria from the operating room between study groups. Major secondary endpoints were propofol consumption, discharge readiness from the recovery room, hypnotic depth as measured by the Narcotrend Index, and adverse events.

RESULTS

Of the 40 children included, data were obtainable from 37. The time until discharge readiness from the operating room was shorter in group NI than in group C, with a difference between medians of 4.76 minutes [95%CI 2.6 to 7.4 minutes]. The same accounts for recovery room discharge times; difference between medians 4.03 minutes [95%CI 0.81 to 7.61 minutes]. Propofol consumption and the percentage of EEG traces indicating oversedation were higher in group C than in group NI. There were no significant adverse events in either study group.

CONCLUSION

Narcotrend Index guidance of propofol delivery for deep sedation in children aged 12-17 years, underdoing gastrointestinal endoscopy results in faster recovery, less drug consumption, and fewer episodes of oversedation than dosing propofol according to clinical surrogate parameters of depth of hypnosis. The results of this study provide additional evidence in favor of the safety profile of propofol/remifentanil for procedural sedation in adequately selected pediatric patients.

Seriously clowning: Medical clowning interaction with children undergoing invasive examinations in hospitals

This qualitative study examined the subjective experience of children undergoing an invasive examination in the hospital when accompanied by a medical clown. In-depth semi-structured interviews were conducted with nine such children and nine of their accompanying parents. The children were patients in two outpatient departments (Pediatric Gastroenterology and a Center for the Sexually Abused) in a hospital in Israel. Interviews were coded thematically using an Atlas.ti software program. Analysis of the interviews indicated that the intervention of the clown positively changed the children's perceptions of the hospital, of experiencing the examination, and of their life narrative. Medical clowns thus appear to be a central, meaningful, and therapeutic source for children undergoing invasive examinations in hospital, as well as for their parents. Therefore, it may be advisable to incorporate medical clowns as an integral part of medical teams performing invasive procedures and to include the clowns in all stages of the hospital visit.

Anesthesia and sedation outside the operating room

The volume of pediatric invasive and noninvasive procedures outside the operating room continues to increase. The acuity and complexity of patient clinical condition has resulted in the expansion of the anesthesiologist's role in remote sites. The anesthesia provider must ensure patient safety by assuring appropriate patient preparation, having available required equipment for monitoring and rescue, planning careful sedation/anesthesia management, continuing vigilance and observation into the recovery phase, and requiring strict discharge criteria. A quality improvement program for the department of anesthesiology should review anesthetic and sedation outcomes of patients both inside and outside the operating room.

Midazolam-ketamine combination for moderate sedation in upper GI endoscopy

OBJECTIVES

The aim of the study was to compare the quality of sedation with 3 different sedation regimens in upper gastrointestinal endoscopy (UGIE) in pediatric patients.

METHODS

One hundred fifty consecutive children who underwent UGIE were randomly assigned to 1 of the 3 medication regimens. Patients in group A (n = 49) received placebo. Forty-five minutes after the placebo was given, repeated intravenous (IV) doses of 0.1 mg/kg midazolam were administered titrated to achieve a level of deep sedation. Patients in group B (n = 51) received oral ketamine instead of placebo, and patients in group C (n = 50) received oral fentanyl instead of placebo with the same methodology and sedation endpoint.

RESULTS

The mean dose of midazolam administered in group B patients was remarkably lower compared with that of groups A and C. Patients in group B showed less distress in IV line placement and separation from parents, higher comfort level, more endoscopist satisfaction, and higher sedation depth compared with groups A and C. The recovery time was significantly shorter in group B. All of the 3 regimens were safe. All of the complications were managed successfully.

CONCLUSIONS

Our data suggest that synergistic sedation with oral ketamine and IV midazolam for UGIE in children is a suitable and safe sedation. The higher rate of vomiting in group B in contrast to previous studies must be caused mainly by the oral route of ketamine administration.
