Green light exposure in children with autism spectrum disorder: a pilot study.

Children with autism spectrum disorder (ASD) are frequently afflicted with sensory processing difficulties, which often impact their ability to cooperate with dental treatment. The objective of this pilot study was to determine the effects of green light exposure on behavior, pain, distress and anxiety in pediatric patients with ASD undergoing a dental prophylaxis. Twelve children diagnosed with ASD, aged 6-17 years, requiring a dental prophylaxis participated in this study. Participants completed two dental prophylaxes, three months apart, one in a standard white light-exposed dental operatory and one in a green light-exposed dental operatory. Behavioral cooperation, pain intensity, physiological stress and anxiety were assessed in all patients. The Wilcoxon matched-pairs signed rank test was used to estimate differences in measured outcomes according to the experimental condition. There was a trend towards reduced uncooperative behavior when children received a dental prophylaxis in the green light-exposed operatory (p = 0.06). Similar levels of heart rate variability (p = 0.41), salivary alpha amylase (p = 0.19), and salivary cortisol (p = 0.67) were observed at the start and end of each visit in both conditions. Green light exposure had no significant effect on pain intensity (p = 0.17) or behavioral anxiety (p = 0.31). These findings suggest a preliminary positive benefit of green light exposure on behavioral outcomes in pediatric patients with ASD and warrants a further, large-scale clinical trial.

Preoperative Multisensory Room Use in Pediatric Patients With Autism: A Randomized Clinical Trial.

Purpose: To evaluate the impact of multisensory room (MSR) use on preoperative anxiety and postoperative outcomes in children with autism spectrum disorder (ASD) undergoing dental treatment with general anesthesia. Methods: Forty children, ages six to 17 years, with ASD re- quiring general anesthesia for dental treatment, participated in this study. Participants were randomized to either the control group (standard pre- operative waiting room) or intervention group (MSR) for 20 minutes prior to general anesthesia induction. Pre- and post-intervention preoperative anxiety were measured. Following surgery, postoperative emergence delirium was assessed. Short- and long-term postoperative pain and adverse behavioral effects were evaluated six hours, 24 hours, one week, and one month post-surgery. Data analysis employed repeated measures analysis of variance with two groups and either two or four time periods. Results: The sample was predominantly male (62.5 percent) and identified as either White or Black (53 percent) and non-Hispanic (60 percent). Preoperative behavioral anxiety levels increased post-intervention in the control group (P<0.05) and decreased in the MSR group (P<0.001). Following surgery, pain intensity was greater in the control group compared to the MSR group at six hours (P<0.05) and 24 hours (P<0.01), and similar at one and four weeks. Pre- and post-intervention measures of preoperative heart rate, postoperative emergence delirium, and behavioral effects were similar between groups and over time. Conclusion: These findings suggest a novel, nonpharmacologic technique that can be utilized by various health care specialties to reduce preoperative anxiety and improve post- operative outcomes in children with autism spectrum disorder.

Auto-Brewery Syndrome and General Anesthesia: A Case Report.

Auto-brewery syndrome (ABS) is a rare condition in which ethanol is endogenously fermented by fungi in the gut following a carbohydrate-rich meal, resulting in intoxication. We present a case of a patient with ABS successfully undergoing general anesthesia for symptomatic wisdom tooth extraction. During previous anesthetics, the patient had experienced postoperative nausea and vomiting (PONV) and awareness under anesthesia. Patients with ABS can be optimized for anesthesia by assessing hepatic function, avoiding perioperative oral carbohydrates, increasing anesthetic depth, multimodal PONV prophylaxis, and avoidance of broad-spectrum antibiotics.

Practice Patterns Among Dentist Anesthesiologists for Pediatric Patients with Autism Spectrum Disorders.

PURPOSE: The purpose of this study was to evaluate practice patterns among dentist anesthesiologists for pediatric patients with autism spectrum disorders (ASD) undergoing sedation for dental procedures. METHODS: An electronic nationwide survey was delivered to all members of the American Society of Dentist Anesthesiologists. The survey assessed provider training and comfort in treating pediatric patients with ASD, perioperative procedures for children with and without ASD, and preferred educational resources for the perioperative management of pediatric patients with ASD. RESULTS: Respondents were 114 dentist anesthesiologists and residents (33.3 percent response rate). Respondents indicated a high comfort level for managing pediatric patients with ASD for sedation (mean equals 91.9±14.74 [SD] percent). The average number of patients with ASD who respondents treat per week was 3.48±2.44). Providers reported making scheduling and staffing accommodations for patients with ASD. More than half of respondents reported no difference between patient groups in medication dosing for sedation and medication regimens used intraoperatively; however, only 43.9 percent of providers indicated using equivalent preoperative medication regimens for both patient groups, and providers reported increased usage of preoperative anxiolytic techniques with patients with ASD. Importantly, 87.7 percent of respondents reported the same incidence of adverse events during the perioperative period between groups. CONCLUSIONS: Findings from this survey suggest there are both similarities and differences in how dentist anesthesiologists practice with pediatric patients with and without autism spectrum disorders. Additional research is warranted to measure the clinical benefits of modified practices for patients with ASD and identify best practices for this vulnerable population.
