Association of glucagon-like peptide receptor 1 agonist therapy with the presence of gastric contents in fasting patients undergoing endoscopy under anesthesia care: a historical cohort study.

PURPOSE: We aimed to estimate the association of glucagon-like peptide 1 (GLP-1) receptor agonist therapy with the incidence of endoscopically visible gastric contents after preprocedural fasting. METHODS: We reviewed the records of esophagogastroduodenoscopy (EGD) performed at our institution between 2019 and 2023 and determined the presence of residual gastric contents from the procedure notes and saved images. We compared patients taking GLP-1 agonists at the time of the procedure (GLP group, 90 procedures) with patients who started GLP-1 agonist therapy within 1,000 days after undergoing EGD (control, 102 procedures). We excluded emergent procedures without fasting, combined EGD/colonoscopy procedures, and patients with known gastroparesis or previous gastric surgery. We estimated the association between GLP-1 agonist therapy and residual gastric contents with a confounder-adjusted generalized linear mixed effect model. RESULTS: Compared with controls, the GLP cohort had a higher age, American Society of Anesthesiologists' Physical Status, and incidence of nausea and diabetes mellitus. Body mass index and fasting duration were comparable between groups. Visible gastric content was documented in 17 procedures in the GLP group (19%) and in five procedures in the control group (5%), with an associated confounder adjusted odds ratio of 5.8 (95% confidence interval, 1.7 to 19.3; P = 0.004). There were five instances of emergent endotracheal intubation in the GLP group vs one case in control and one case of pulmonary aspiration vs none in control. CONCLUSIONS: In fasting patients, GLP-1 agonist therapy was associated with an increased incidence of residual gastric contents, potentially posing an additional risk of periprocedural pulmonary aspiration.

RéSUMé: OBJECTIF: Notre objectif était d'estimer l'association d'un traitement par agonistes des récepteurs du peptide-1 de type glucagon (glucagon-like peptide 1, GLP-1) avec l'incidence de contenu gastrique visible par endoscopie malgré le jeûne préopératoire. MéTHODE: Nous avons examiné les dossiers des œsophagogastroduodénoscopies (OGD) réalisées dans notre établissement entre 2019 et 2023 et déterminé la présence de contenu gastrique résiduel à partir des notes d'intervention et des images enregistrées. Nous avons comparé les patient·es prenant des agonistes du GLP-1 au moment de l'intervention (groupe GLP, 90 procédures) avec les patient·es qui ont commencé un traitement par agonistes du GLP-1 dans les 1000 jours suivant l'OGD (groupe témoin, 102 procédures). Nous avons exclu les procédures d'urgence sans jeûne, les procédures combinées OGD/coloscopie et les patient·es présentant une gastroparésie connue ou une chirurgie gastrique antérieure. Nous avons estimé l'association entre le traitement par agonistes du récepteur GLP-1 et le contenu gastrique résiduel à l'aide d'un modèle linéaire généralisé à effets mixtes ajusté en fonction des facteurs de confusion. RéSULTATS: Par rapport aux témoins, la cohorte GLP était plus âgée, de statut physique selon l'American Society of Anesthesiologists plus élevé et présentait une incidence plus élevée de nausées et de diabète. L'indice de masse corporelle et la durée du jeûne étaient comparables entre les groupes. Du contenu gastrique visible a été documenté dans 17 procédures dans le groupe GLP (19 %) et dans cinq procédures dans le groupe témoin (5 %), avec un rapport de cotes ajusté associé de 5,8 (intervalle de confiance à 95 %, 1,7 à 19,3; P = 0,004). Il y a eu cinq cas d'intubation endotrachéale urgente dans le groupe GLP vs un cas dans le groupe témoin et un cas d'aspiration pulmonaire vs aucun dans le groupe témoin. CONCLUSION: Chez la patientèle à jeun, le traitement par agonistes des récepteurs du GLP-1 a été associé à une incidence accrue de contenu gastrique résiduel, ce qui pourrait entraîner un risque supplémentaire d'aspiration pulmonaire périprocédurale.

Pediatric ambulatory anesthesia.

Pediatric patients often undergo anesthesia for ambulatory procedures. This article discusses several common preoperative dilemmas, including whether to postpone anesthesia when a child has an upper respiratory infection, whether to test young women for pregnancy, which children require overnight admission for apnea monitoring, and the effectiveness of nonpharmacological techniques for reducing anxiety. Medication issues covered include the risks of anesthetic agents in children with undiagnosed weakness, the use of remifentanil for tracheal intubation, and perioperative dosing of rectal acetaminophen. The relative merits of caudal and dorsal penile nerve block for pain after circumcision are also discussed.

Challenges in pediatric ambulatory anesthesia: kids are different.

The care of the child having ambulatory surgery presents a specific set of challenges to the anesthesia provider. This review focuses on areas of clinical distinction that support the additional attention children often require, and on clinical controversies that require providers to have up-to-date information to guide practice and address parental concerns. These include perioperative risk; obstructive sleep apnea; obesity; postoperative nausea and vomiting; neurocognitive outcomes; and specific concerns regarding common ear, nose, and throat procedures.

Use of dexmedetomidine in awake craniotomy in adolescents: report of two cases.

Awake craniotomy is a key tool in resection of lesions near critical functional regions, particularly the speech area. Craniotomy with an awake portion for mapping may be performed in carefully selected adolescents and preteenaged children. A number of different regimens may be used for sedation and anesthesia in these cases. We describe two adolescent patients in whom awake craniotomy was performed using an intravenous anesthesia technique with dexmedetomidine and without need for airway instrumentation.

Herbal and homeopathic medication use in pediatric surgical patients.

BACKGROUND: Patients who present for surgery may be using herbal or homeopathic preparations; adverse effects of some of these substances include bleeding, cardiovascular changes, and liver dysfunction. Little information is available on the frequency of use in the pediatric surgical population. METHODS: With institutional approval, a survey was conducted to assess the use of vitamins, nutritional supplements, or herbal or homeopathic preparations in children presenting for surgery in five geographically diverse centers in the USA. RESULTS: A total of 894 completed surveys showed that overall, 3.5% of pediatric surgical patients had been given herbal or homeopathic medications in the 2 weeks prior to surgery. Most substances were prescribed by parents. The use of these medications did not differ between children with coexisting diseases and those without; use was also not different among ethnic groups or by residence setting (city, suburban, rural). There was a significant difference between the west coast centers in the study compared with the rest of the country (7.5% of patients in Palo Alto, CA; 5.5% of patients in Seattle, WA; 1.5% of patients in Chicago, IL; and 1.9% in Virginia and Delaware used herbal or homeopathic remedies). The most prevalent substance given to children presenting for elective surgery was Echinacea. CONCLUSIONS: Herbal and homeopathic medications are used by a small percentage of pediatric patients presenting for elective pediatric surgery patients. Use of these substances should be addressed in the preoperative history.

Pain management for pediatric ambulatory anesthesia.

PURPOSE OF REVIEW: New developments in analgesic drugs and techniques are being applied to the pediatric population. Appropriate pain management for ambulatory surgery patients helps to facilitate early discharge and minimize postoperative morbidity. RECENT FINDINGS: A variety of opioid-related drugs, as well as novel delivery routes for opioids, have been reported in the pediatric population. New pharmacokinetic information for acetaminophen has resulted in revised dosage recommendations; applications of the nonsteroidal antiinflammatory agents are also discussed. Furthermore, regional anesthesia and adjuncts are useful in the pediatric ambulatory surgery patient. SUMMARY: Recent data on techniques for pain management after pediatric ambulatory surgery will help the anesthetist develop a comprehensive plan for the postoperative period.
