Student training in administering inferior alveolar nerve block anesthesia with a simple manufactured simulation model.

OBJECTIVE: To compare the effectiveness of administering inferior alveolar nerve blocks (IANB) for the first time with or without a previous practical lesson using a simple manufactured simulator. METHODS: This was a study designed to compare students' first administration of IANB anesthesia during 2022, with or without a previous practical lesson. Students were randomized into two groups. The experimental group attended both theoretical lessons and a practical lesson with a simulator device, while the control group attended only theoretical lessons. The theoretical lesson included usual contents such as anatomy, physiology, technical maneuvers for administering anesthesia, tips, and complications, and the practical lesson consisted of the administration of anesthesia using a simple manufactured simulator. After students applied their first IANB, its efficacy, and their answers to a questionnaire on a 5-point Likert scale were recorded. Statistical analysis consisted of the Chi-square test (p < 0.05). RESULTS: The study recorded 60 anonymous surveys. The main difference observed was in instrument handing (p < 0.05), and there was a tendency in the ease of recognition of the anatomical marks used for the technique-pterygomandibular raphe and coronoid notch of the mandible (p = 0.08 and 0.11, respectively). No difference in success was observed (p > 0.05). Self-confidence and personal feelings did not differ statistically. All students agreed strongly or partially that training with the simulator model was helpful. CONCLUSION: Students who used simple manufactured simulators achieved better outcomes for instrument handling, and possibly for identification of anatomical landmarks, than those who received only theoretical lessons.

A preliminary study on the assessment of pain using figures among patients administered with dental local anesthesia for mandibular third molar extraction.

The aim of this study was to clarify or determine any possible association between pain reports with a visual analogue scale (VAS) and a figures based scale. This research was a preliminary study aimed at developing a new pain scale without any verbal description. Healthy Japanese patients aged 20 to 39 years who received anesthetic injections for mandibular third molar extraction at our department were enrolled. Regarding pain from dental local anesthetic injections, we recorded figures selected by participants (among options of a circle, triangle, square, bar, and cross), and VAS scores. Overall, 29 men and 31 women participated in the study. Pain caused by local dental anesthesia tended to remind both men and women of the triangle among the suggested figures. Furthermore, patients who chose a cross also reported higher VAS scores than those who chose other figures. Acute pain caused by local dental anesthesia was associated with triangles, and patients who selected a cross were associated with higher VAS scores. The results of this study provide clinicians with important information for dental practice, and could prove useful in developing new pain scales.

A comparative assessment of efficacy and preference between needleless device INJEX and insulin syringe for anesthetizing primary maxillary teeth in children aged 4-9 years: A split-mouth crossover randomized clinical study.

insulin syringe for anesthetizing primary maxillary teeth in children aged 4-9 years. Materials and Methods: This randomized clinical study included 46 children aged 4-9 years. The patients were digitally allotted to receive 4% articaine for extractions of primary maxillary teeth, either using needleless device INJEX or insulin syringe on each side of the maxillary arch, in two different appointments after a 1-week washout period. Pain perception was measured by the subjective (Faces Pain Scale-Revised [FPS-R]) and objective pain scores (Face, Legs, Activity, Cry, and Consolability [FLACC]) and hemodynamic parameters (heart rate and oxygen saturation) during LA administration and during extractions. After the second appointment, children were asked about their preference between needleless device INJEX and insulin syringe. Results: On evaluating subjective pain scores with FPS-R, intergroup differences between the INJEX and insulin syringe groups were found statistically insignificant, both during LA administration (P = 0.101) and extraction (P = 0.080). However, on assessing pain objectively during extraction using FLACC, the mean pain score was less with insulin syringe (2.78) as compared to INJEX (4.72) and the difference was statistically significant (P = 0.000). There was no significant difference in patient preference between the two methods. Conclusion: Pain perception was minimal during local anesthesia administration using needleless device INJEX; however, its clinical efficacy during extractions was reported to be lower than insulin syringe. Background: Managing pain in children is the most challenging task as it forms the foundation for instilling positive behavior toward dental treatment. Adequate local anesthesia (LA) is the cornerstone of pain management. However, the fear of needles, particularly in young children, can result in complete avoidance and refusal of treatment. Aim: This study aimed to evaluate and compare the efficacy and preference between needleless device INJEX and.

Evaluation of maximum dose intravenous midazolam used in dental intravenous sedation: a West of Scotland regional audit.

Background Intravenous (IV) midazolam sedation is commonly used in the delivery of dentistry for phobic patients. There is currently no guidance on a maximum dose for use specifically in dentistry. Dentists practise with the British National Formulary recommended maximum dose of 7.5 mg; however, anecdotally, this is often exceeded. We aim to evaluate prescribing and propose recommendations for a maximum dose for dentists.Method Data was collected from ten dentists across four Scottish health boards regarding their last 20 IV sedation patients, giving a total of 200. Data obtained from standard Dental Sedation Teachers Group IV logbooks included: dose of midazolam administered; justification for doses over 7.5 mg; flumazenil or supplemental oxygen usage; significant medical/social factors; and the Ramsay Sedation Score.Results Mean midazolam dose was 6.1 mg with a range of 14 mg. The recommended maximum dose of 7.5 mg was exceeded in 28% of cases. The mean sedation score was 2.7 and there were no reported adverse events or use of flumazenil.Conclusion IV midazolam is an effective way to achieve conscious sedation in dentistry. Acknowledgement of current off-label prescribing is important; however, 7.5 mg as a recommended maximum dose is too conservative as it is regularly exceeded without adverse events. Further investigation and expert opinion is required to set a maximum dose specifically for dentistry.

Comparative Assessment of Pain during Infiltration by a Two-stage Infiltration Technique: A Double-blind Clinical Trial.

AIM: The aim of this study was to assess and compare the pain during infiltration by a modified two-stage local anesthetic infiltration technique under topical anesthesia (TA). MATERIALS AND METHODS: In this cross-over double-blind study, 30 volunteers participated, where two groups were given single-stage infiltration and the other two had two-stage infiltrations. Depending upon the infiltration technique (one- or two-stage) and the use of TA, the patients were randomly divided into four groups. Local anesthesia (LA) was administered by infiltration into the mucobuccal fold of the maxillary central incisor, and the pain perceived during the infiltration in each group was recorded. The volunteers were recalled after 24 hours to assess the tenderness at the injection site. The volunteers were recalled 2 weeks after infiltration for the subsequent groups to assess the pain for this cross-over study. RESULTS: A statistically significant difference was observed in the pain perceived when TA was used and when the infiltration was done in two stages. Regarding the pain at the site of injection after 24 hours, no significant difference was observed among the volunteers. CONCLUSION: Topical anesthesia was effective in reducing the pain of injection when compared to placebo. The pain of injection is further reduced with a two-stage infiltration technique after TA application. CLINICAL SIGNIFICANCE: Topical anesthesia can be used routinely before infiltration, and LA infiltration injections are less painful if administered in two stages.

Evaluation of therapeutic effect and health economics of general anesthesia and routine outpatient dental treatment in children with severe early child caries.

OBJECTIVES: To evaluate the efficacy and health economics of the comprehensive therapy for the children with severe early child caries (S-ECC) under dental general anesthesia (DGA) and conventional outpatient treatment to provide references for dentists and parents in the choice of clinical treatment. METHODS: A retrospective cohort study was conducted on S-ECC children aged 36-71 months and who received dental treatment under general anesthesia or routine outpatient situation. The filled tooth survival rate, treatment cost, and cost-filled tooth survival time of the two groups were compared, and the curative effect and health economics was evaluated. RESULTS: The filled tooth survival rate of the DGA group was higher than that of the routine outpatient group (P<0.05). The average direct medical cost per filled tooth was significantly higher in the DGA group than in the routine outpatient group (P<0.05). The direct medical cost-filled tooth survival time ratio in the DGA group was higher than that in the routine outpatient group (P<0.05), but no significant difference was observed in the total medical cost-filled tooth survival time ratio (P>0.05). CONCLUSIONS: Compared with the conventional outpatient treatment group, the treatment outcomes of S-ECC under general anesthesia were better, and the costs were higher. However, no significant difference was observed in the total medical cost-filled tooth survival time between these two groups, and the conventional outpatient treatment did not have evident economic advantages.

Compliance of Special Health Care Needs and Healthy Pediatric Patients with Preventive Visits after Dental Treatment under General Anesthesia.

Purpose: To identify compliance of special health care needs and healthy pediatric patients with preventive dental appointments after treatment under general anesthesia (GA).
Methods: Records of special health care needs (SHCN) patients treated under GA in 2015 and 2016 were reviewed. The control group consisted of randomly selected healthy patients also treated under GA in the same time period and hospital. Patient demographics were compared, and the number of preventive visits was recorded for 24 months after GA.
Results: The sample consisted of 141 SHCN patients and 142 healthy children. The average number of preventive visits post-GA appointment was 2.74 out of a recommended nine visits over two years for the study population. There was a statistically significant difference in the level of compliance based on age and referral source, but there was no difference based on health status.
Conclusion: Compliance with preventive dental visits after treatment under GA among all pediatric patients, regardless of health status, must be improved. Caregivers must be further educated to implement change and barriers to care must be explored.

A Retrospective Comparison of Dental Treatment under General Anesthesia Provided for Uncooperative Healthy Patients and Patients with Special Health Care Needs.

Background/Objective: This retrospective comparative analysis evaluates the patterns of dental treatment undertaken on uncooperative healthy and special health care needs patients with respect to different age categories. Study design: This study reviewed the data from 342 patients (205 male and 137 female), between the ages of 1 and 12 at the time of the treatment, who had received comprehensive dental treatment under general anesthesia in the operating rooms of the Faculty of Medicine, Cukurova University from January 2016 through December 2018. Patient records were divided into two groups according to the patient's medical and mental conditions. SHCN patients (272 patients) with at least one type of mental, medical or physical disability were assigned to Group S and uncooperative healthy patients (70 patients) were assigned to Group H. Treatment modalities of restorative procedures, number of extracted teeth, pulp therapy, and other dental procedures were compared between these groups with respect to eruptional stages in the dentition (<6 years and 6-12 years) Results: There was no significant difference between groups H and S in terms of the mean duration of dental treatment among age categories in both groups. The mean number of extracted teeth was significantly greater in Group S. The mean number of teeth treated by restorative procedures in groups H and S were 4.40 and 4.40, respectively, showing no significant difference. Conclusions: Comparison of two different groups, with patients who have received comprehensive dental treatment in an operating room, revealed that the number of teeth extracted was significantly higher for the SHCN patients. On the basis of our results, it was concluded that medical and mental conditions affect dental treatment modalities. Preventive treatment strategies are particularly required for patients with SHCN and it is important to educate patients and their parents/caregivers on the importance of home dental care.

Volume and effectiveness assessment of articain 4% versus mepivacaine 2% used in third molar surgery: randomized, double-blind, split-mouth controlled clinical trial.

BACKGROUND: The different indications for extraction of the lower third molars, require resources to manage pain and discomfort, such as, for example, adequate anesthetic techniques, and the type of anesthetic used can influence the management of pain in tooth extractions. Few studies in the literature compare the anesthetics 4% articaine hydrochloride and 2% mepivacaine hydrochloride showing evidence that both allow for successful pain management. This study sought to compare the volume, efficacy and safety of these two anesthetic drugs, both associated with epinephrine at a ratio of 1:100,000, used in the extraction of lower third molars. MATERIAL AND METHODS: A controlled, clinical, split-mouth compared these both local anesthetics in a sample of 20 patients requiring bilateral extraction of teeth. Pain was the main parameter to be assessed by means of the visual analogue scale (VAS) applied during and immediately after the surgery. Hemodynamic parameters, adverse events, presence of paresthesia and satisfaction of patients and surgeon were also analysed. RESULTS: Pain management was more effective with mepivacaine up to two hours after surgery (p=0.014), whereas the surgeon was more satisfied with the use of articaine during divulsion and suture (p<0.05). However no statistically significant differences were found between both anesthetics regarding pain perception. CONCLUSIONS: It was observed that both anesthetics are efficient and safe in the management of pain for extraction of third molars, in which less amount of mepivacaine is needed. The satisfaction of patients and surgeon was the same for both anesthetics, with articaine being highlighted during divulsion and suture.

Oral Health Inequalities in 0-17-year-old Children Referred for Dental Extractions Under General Anaesthesia in Wolverhampton, 2013-2017.

OBJECTIVE: Describe the inequalities in oral health in children treated in a hospital located in a deprived urban area in the UK. RESEARCH DESIGN: Case-note review of 1911 0-17-year-olds who underwent dental extractions under a general anaesthetic (DGA). MAIN OUTCOME MEASURES: Associations between Age, Ethnicity, Year-of-Treatment and Index of Multiple Deprivation (IMD) with the number of teeth extracted. Analysis used multilevel modelling assuming a Poisson distribution. RESULTS: Mean number of teeth extracted was higher in the youngest children treated aged 0-5 years (relative risk coefficient, (RR=exp(ß)=1.39; 95% CI 1.24 to 1.56) compared to those aged 6-17 years and in 'Other Whites' (predominantly immigrants from Eastern Europe) (RR=exp(ß)=1.34; 95% CI 1.25 to 1.43), 'South Asians' (RR=exp(ß)=1.15; 95% CI 1.08 to 1.23) but fewer in the 'Black' ethnic group (RR=exp(ß)=0.85; 95% CI 0.76 to 0.95). DGA increased during the study with more teeth extracted in 2015, 2016 and 2017 (RR=exp(ß)=1.12, 95% CI 1.22, 1.25) and with a negative gradient in the rate of DGA's (per decile) in children from the most deprived to most affluent locations (RR=exp(ß)=0.98; 95% CI 0.97 to 0.99). CONCLUSIONS: Significant oral health inequalities exist in children from a deprived urban area in the UK. A preventive approach to children's oral health is needed to reduce such inequalities, including public health and healthcare agencies to informing parents of children whose first language is not English about dental caries.

Assessment of conduction anesthesia effectiveness using the angulated needle approach for the inferior alveolar nerve block.

BACKGROUND: Ambulatory painless surgery is dependent on local anesthesia effectiveness. AIM: Evaluating the anesthetic efficacy of the angulated needle approach (ANA) for the inferior alveolar nerve block (IANB). MATERIAL AND METHOD: Group I received direct IANB; group II received indirect IANB; group III received the IANB with ANA. The quality of anesthesia score (QAS), numerical pain intensity score (NRS), onset time of full anesthesia (OT), and perianesthetic complications were measured. RESULTS: Ninety patients (mean age: 37.47 ± 18.90, p = 0.027) of both sexes were split into three equal groups. Group III had the lowest QAS value with the success rate of 93.3%, compared to the statistically significantly worse QAS values of group II, with the success rate of 80% (p = 0.016). Group II had the statistically significant highest NRS values relative to group I (p = 0.002) and group III (p = 0.000001). The shortest OT occurred in group I, when compared to group II (p = 0.000484) and group III (p = 0.000498). The transient syncope and positive aspiration occurred in single cases. CONCLUSION: The ANA for the IANB could successfully serve as a "first choice", or as an "addendum technique" in the cases of multiple failed attempts for direct and indirect IANB techniques.

Pain assessment during mandibular nerve block injection with the aid of dental vibe tool in pediatric dental patients: a randomized clinical trial.

OBJECTIVE: This study aimed to evaluate the effectiveness of DentalVibe in pain reduction during local anesthetic injection compared to traditional injection in pediatric patients. METHOD AND MATERIALS: This cross-over randomized controlled clinical trial included a sample of 60 children, aged 5 to 7 years, who were selected based on the need for local anesthesia for bilateral mandibular pulpotomy treatment. They were randomly allocated into two groups. Each group received two mandibular nerve block injections, with a 2-week interval as the washing out period. At first appointment, mandibular nerve block injection was performed either with vibration using DentalVibe at the injection site or benzocaine gel 20% applied before local anesthetic injection; the alternative technique was used at the second appointment. In each visit subjective pain was evaluated using the Wong-Baker FACES Pain Rating Scale and objective pain was evaluated using the FLACC (Face, Legs, Activity, Cry, Consolability) scale. RESULTS: Assessment using the Wong-Baker FACES Pain Rating Scale showed that the mean pain levels in DentalVibe and traditional injection groups were 0.80 ± 1.34 and 2.60 ± 3.22, respectively. The mean pain levels according to the FLACC scale were 2.20 ± 2.04 and 3.13 ± 2.30 in the DentalVibe and traditional injection groups, respectively. Both scales showed statistically significant differences between the two groups in favor of DentalVibe (P < .001). A positive significant correlation between the two scales in the two interventions was recorded, where the Spearman rho was 0.41 for the DentalVibe group, and 0.52 for traditional injection group (P < .001). CONCLUSION: Compared to the traditional approach, DentalVibe reduced pain sensation during mandibular nerve block injection in pediatric patients.

Assessment of photobiomodulation therapy by an 8l0-nm diode laser on the reversal of soft tissue local anesthesia in pediatric dentistry: a preliminary randomized clinical trial.

During the injection of local anesthesia in pediatric dental procedures, from the injection time until the elimination of tissue anesthesia, inevitable problems were reported. According to the encouraging results of previous studies addressing the positive effects of laser therapy on increasing the microcirculation, we aimed to investigate the clinical effect of photobiomodulation therapy on the reversal of soft tissue anesthesia in children. Using a split-mouth design, 34 children aged 4 to 8 years old, candidate for receiving local infiltration injection at both right and left side in mandible, were enrolled in the study. The mandibular right and left quadrants were randomly assigned to groups of laser or sham laser: in laser side, patients received 810-nm laser irradiation, and in the sham laser group, the patients had the laser in off mode at 45 min after injection with an interval of 7-10 days between two sessions of each quadrant treatments. The degree of anesthesia was evaluated using the palpation technique alternately every 15 min. Data were analyzed using paired sample t test and multiple linear regression test. The mean duration of anesthesia expressed in minutes was equal to 145.15 ± 23.27 and 188.82 ± 12.31 for the laser group and sham laser group, respectively. There was a significant difference in duration of anesthesia between two groups (P < 0.001). Considering the results and limitations of the present study, photobiomodulation therapy by 810-nm diode laser can be proposed as a non-invasive method in order to reduce the duration of anesthesia in pediatric patients.

[Objective assessment of mental nerve local anesthesia]. / Ob''ektivnaia otsenka urovnia mestnogo obezbolivaniia podborodochnogo nerva.

AIM: To study the reaction of the mental nerve to selective stimulation of thin nerve fibers by thermal stimuli during conduction anesthesia. MATERIAL AND METHOD: The pilot study involved 24 healthy volunteers: 13 subjects were injected with a 4% solution of articaine-containing anesthetic with a vasoconstrictor in a ratio of 1:200 000 (pH 4.8-5.4) and 11 subjects - a 3% solution of mepivacaine-containing local anesthetic without a vasoconstrictor (pH value 5.8-6.4). The registration of evoked potentials was performed twice: before local anesthesia and 5 minutes after anesthesia. With the help of disposable carpal dental injectors, local anesthesia was performed near the mental foramen in order to anesthetize the innervation region of the mental nerve through a conductive type. The evoked potentials (VP) were recorded on a Nicolet instrument (USA) with Bravo evoked potentials software. The study of thermal EPs was performed using a Contact heat evoked potential stimulator (CHEPS) device ('Medoc Ltd, Ramat Yishai', Israel). The base and peak temperature were set at 33 and 54 °C, correspondingly. RESULTS: The evoked potentials for thermal stimulation demonstrated a significant decrease in the amplitude of all components and the elongation of the LP of the main negative-positive N2-P2 complex after anesthesia compared with the initial thermal EP. The complete disappearance of thermal responses was observed in 14 (58%) of 24 study participants, minor changes were seen in 3 (12.5%) cases only. The total response disappearance was observed in 10 (77%) of 13 participants after articaine and in 3 (27%) of 11 - after mepivacaine (p<0.05), weak changes were registered in 2 (15%) cases in the articaine group and in 1 (9%) case in the mepivacaine group. CONCLUSION: A 4% solution of articaine is somewhat more effective for pain relief of teeth and bone since it often causes deeper anesthesia, and a 3% solution of mepivacaine without a vasoconstrictor is physiologically more suitable for working with soft tissues.

Frequency, variation and cost of dental extractions for adults in secondary care in Great Britain.

Aims We have conducted a survey of administrative data, aiming to investigate the reported provision of dental extraction under general anaesthesia in the NHS for adults in secondary care in the following aspects: 1) anaesthetic data accessibility by NHS organisations; 2) the number and proportion of dental extraction episodes by anaesthetic modality and procedure type; 3) the economic cost of dental general anaesthesia (DGA) for adults; 4) variations in the anaesthetic provision between commissioning regions and organisation types. Methods We collected data from individual secondary care NHS organisations that provide dental extraction services in England, Wales and Scotland. A data collection form was devised to capture the number of episodes of dental extraction under each relevant oral surgery procedure code per anaesthetic modality per institution from October 2015 to September 2016. Results The majority (64.0%, n = 96,659) of the episodes were categorised into an anaesthetic modality; 39.2% (n = 37,902) under general anaesthesia, 18.7% (n = 18,050) under sedation, and 42.1% (n = 40,707) under local anaesthesia. The majority of sedation provision (84.9%) derived from dental hospitals. A substantial proportion (37.0%) of the episodes could not be assigned an anaesthetic modality. Variations in dental general anaesthesia activity were observed with respect to the commissioning regions and organisation types. The annual cost of adult DGA from 81 out of 150 organisations that provided DGA data was estimated to be over £19 million, based on the NHS payment by results tariff 2015-2016. Conclusion Our data suggest that the number of adult DGA episodes and the associated cost are considerable, and highlights the scope for improving the quality of data for commissioners and providers to support discussions over patient pathways.

European Society of Anaesthesiology Task Force on Nitrous Oxide: a narrative review of its role in clinical practice.

Nitrous oxide (N2O) is one of the oldest drugs still in use in medicine. Despite its superior pharmacokinetic properties, controversy remains over its continued use in clinical practice, reflecting in part significant improvements in the pharmacology of other anaesthetic agents and developing awareness of its shortcomings. This narrative review describes current knowledge regarding the clinical use of N2O based on a systematic and critical analysis of the available scientific literature. The pharmacological properties of N2O are reviewed in detail along with current evidence for the indications and contraindications of this drug in specific settings, both in perioperative care and in procedural sedation. Novel potential applications for N2O for the prevention or treatment of chronic pain and depression are also discussed. In view of the available evidence, we recommend that the supply of N2O in hospitals be maintained while encouraging its economic delivery using modern low flow delivery systems. Future research into its potential novel applications in prevention or treatment of chronic conditions should be pursued to better identify its role place in the developing era of precision medicine.

The Prevalence and Factors Associated with Sibling-Recurrent Dental Treatment Under General Anesthesia at an Academic Institution.

Purpose: The purpose of this study was to assess the prevalence of and factors that contribute to sibling-recurrent dental general anesthesia (DGA) at the Department of Pediatric Dentistry, Virginia Commonwealth University, Richmond, Va., USA. Methods: Subjects were recruited from July 25, 2017 to March 15, 2018. The guardian of patients with siblings who attended a university pediatric dental clinic were provided a questionnaire to assess the prevalence and factors associated with recurrent DGA. A provider survey was completed to ensure inclusion/exclusion criteria were met. Results: A total of 40 families with a child presenting for general anesthesia (GA) and who had at least one sibling were included in the study. Of these, 45 percent had sibling-recurrent GA treatment; 20 percent of patients had one sibling; and 25 percent had two or more sibling-recurrent DGA (P<.05). Additionally, 13 percent of the children currently presenting for GA had already been treated under GA, and 15 percent of the siblings previously treated with GA had recurrent caries after GA. Conclusions: Sibling-recurrent general anesthesia is high at Virginia Commonwealth University's Pediatric Dentistry Clinic. This increased prevalence could be due to parental acceptance and positive experiences with DGA. Dental providers should be proactive with prevention of recurrent DGA.

Preoperative Assessment of Obstructive Sleep Apnea in the Ambulatory Anesthesia Patient: A Survey of Oral and Maxillofacial Surgery Providers.

PURPOSE: Oral and maxillofacial surgeons often treat patients with both diagnosed and undiagnosed obstructive sleep apnea (OSA). Patients with OSA are at substantial risk of perioperative and postoperative complications after receiving intravenous sedation, general anesthesia, or postoperative opiate analgesia. The purpose of this study was to determine whether oral and maxillofacial surgery (OMS) providers are screening patients for perioperative and postoperative risks related to OSA before office-based ambulatory anesthesia. MATERIALS AND METHODS: SurveyMonkey software (SurveyMonkey, San Mateo, CA) was used to distribute a survey to 1,658 community- and hospital-based OMS providers in the United States. A response rate of 17.4% (n = 288) was achieved. The 27-question survey was created to obtain demographic information and to assess the preoperative anesthesia routine of the OMS providers. The questions were developed based on American Society of Anesthesiologists guidelines and the STOP-Bang questionnaire to determine the quality and rate of screening for OSA before office-based ambulatory anesthesia procedures. RESULTS: All incomplete survey responses were excluded from analysis. Demographic analysis showed that 73.61% of the 288 respondents were in private practice only, with no hospital affiliation. Of the respondents, 81.88% reported performing fewer than 50 hospital operating room procedures per year, 81.60% reported performing more than 200 office-based ambulatory anesthesia cases per year, and 96.19% reported performing their own office-based ambulatory anesthesia. In this cohort, only 34.7% of OMS providers stated that they asked patients OSA-specific screening questions, whereas 74.3% reported asking other preoperative anesthesia questions (χ2 = 91.0, df = 1, P < .0001). CONCLUSIONS: Most of the surveyed OMS providers are not screening pre-anesthesia patients for OSA with a quantifiable method such as the STOP-Bang questionnaire. These findings identify a need to investigate the rate of undiagnosed OSA syndrome in the OMS office-based ambulatory anesthesia patient population. The STOP-Bang questionnaire may be a useful tool to better assess for anesthesia risk and modify management accordingly.
