Mortality and Morbidity in Office-Based General Anesthesia for Dentistry in Ontario

Does anesthesia duration or number of cases per patient predict safety events?

BACKGROUND

The need for dental rehabilitation under general anesthesia is increasing, with varying needs between patients. Mortality has been found to be a rare event in these patients; however other perioperative events can and do occur. Previous studies have established increased incidence of perioperative events with younger, sicker children, and longer anesthetics, however, no studies to date have evaluated if the incidence of perioperative events is more closely associated with one long anesthetic or multiple anesthetics per patient.

AIMS

To evaluate the association of perioperative events related to single anesthetic duration or number of anesthetics per patient for dental rehabilitation.

METHODS

After Children's Wisconsin Human Research Protection Program determined this quality activity did not meet the definition of human subjects research, we performed an epidemiologic observational evaluation by extracting all dental related cases (dental alone or with oral surgeon vs. dental with other specialties) with an associated general anesthesia encounter from Children's Wisconsin electronic data warehouse from June 1, 2015 to December 31, 2021. These cases occurred at a free-standing children's hospital or associated pediatric-only ambulatory surgery center. The risk of perioperative safety events was analyzed for previously identified risk groups such as American Society of Anesthesiologists Physical Status (ASA-PS), patient age, anesthesia case time with the addition of number of dental cases per patient.

RESULTS

In this study, 8468 procedures were performed on 8082 patients. Of this cohort, 7765 patients underwent one procedure for dental care while 317 patients underwent a total of 703 dental-related procedures, ranging from two to five procedures per patient. Multivariable logistic regression identified increased risk of perioperative events in patients with ASA-PS 3 (n = 1459, rate 1.78%, p value .001, OR 5.7, CI 2.1-15.5) and ASA-PS 4 (n = 86, rate 5.8%, p < .001, OR 17.2, CI 4.4-67.3), anesthesia duration (p < .001, OR 1.46, CI 1.21-1.76), but no increased risk with number of anesthetics per patient (p value .54, OR 0.81, CI 0.4-1.61).

CONCLUSIONS

Limiting dental care under general anesthesia to multiple short cases may decrease the risk of perioperative events when compared to completing all treatment in one long operative session.

The impact of general medical health status, demographical, and patient-specific variables on need for dental treatment of children and adolescents under general anesthesia

OBJECTIVES

Aim of this retrospective study was to examine the influence of general medical, demographical, and other patient-specific factors on the need for dental treatment under general anesthesia in children and adolescents at Saarland University Hospital. For assessment of the clinical treatment need, a mixed dt/DT (decayed teeth) was introduced.

MATERIALS AND METHODS

A total of 340 patients under 18 years of age who received restorative-surgical dental treatment between 2011 and 2022 were anonymously enrolled. Demographic and other patient-specific data, general medical health, oral health, and treatment related data were recorded. In addition to descriptive analysis, Spearman-Rho-test, Mann-Whitney-U-test, Kruskall-Wallis-test and Chi-square-test were used.

RESULTS

More than half of the patients (52,6%) were in general health, but non-cooperative. The majority of the patients (66.8%) was between 1 and 5 years of age (p < 0,001). Mean dmft was 10.95 ± 4.118, mean DMFT was 10.09 ± 7.885, and mean dt/DT was 10.79 ± 4.273. Analysis showed that communication difficulties significantly influenced dmft (p = 0.004), DMFT (p = 0.019), and dt/DT (p < 0.001). Type of insurance significantly affected dmft (p = 0.004) and dt/DT (p = 0.001). There was no significant effect of ASA on caries experience, however on prevalence of severe gingivitis (p < 0.001), number of extractions (p = 0.002), and need for repeated treatment (p < 0.001).

CONCLUSIONS

Need for dental treatment in the present collective was high, independent of the considered variables. Non-Cooperativeness along with ECC was the main indication for dental general anesthesia. The mixed dt/DT was the most precise survey to evaluate clinical treatment needs.

CLINICAL RELEVANCE

Given the enormous demand for these rehabilitations with strict selection, it is imperative to create more treatment capacities for patients mandatorily requiring general anesthesia by avoiding it in healthy patients.

Postoperative Morbidity of Dental Paediatric Patients Treated under General Anaesthesia at a University Hospital: An Observational Study

Aims

To assess prevalence of postoperative morbidity signs and symptoms in children treated under GA, and to investigate the association between pre- and intra-operative factors with postoperative morbidity. Study design and

Methods

Prospective, observational study supported by pre-operative, intra-operative, and postoperative questionnaire conducted on paediatric patients treated for dental reasons under general anaesthesia at a university hospital.

Results

Hundred and fifty patients were included with average age 5.5 years. The majority (92%) experienced at least one postoperative morbidity sign and symptom on the day of treatment under GA and the majority of symptoms subside by the third day. Dental pain (81.3%), sleepiness (70%), and poor appetite (46.7%) were the most frequently reported. Logistic regression analysis showed that age, gender, type of treatment provided, use of LA, and duration of procedure were significantly associated with postoperative morbidity.

Conclusions

Most patients experienced one or more morbidity sign/s or symptom/s during first postoperative day and the majority subsides by the third day. Dental pain and poor appetite were the most and long lasting reported. Factors that would predict the occurrence of postoperative morbidity were gender, patient's age, and duration of procedure.

Dental decision-making under general anesthesia for patients with disabilities: A qualitative study

AIMS

This paper explores the variables which influence decision-making processes in dentists providing dental care for people with disabilities under general anesthesia (GA).

METHODS

Face-to-face semi-structured interviews were undertaken on a purposive sample. Audio recordings were transcribed and checked for accuracy. Using thematic content analysis methods open codes were developed inductively. Codes were analyzed further by three authors adopting a deductive approach, leading to final coding, sorting and themes, subtheme and framework development.

RESULTS

Three themes emerged. The first theme explored Shared Decision Making, or lack thereof, as it influenced clinical reasoning. The second (Systematic, Analytical) and third (Intuition, and heuristics) themes explored features of clinical judgment as considered under dual process theory. Dentists primarily used intuitive decision-making processes and heuristic styled processes (or cognitive mental frames) assisted in intuition to extract teeth, without engaging type 2 processes.

CONCLUSION

The dentists experience subtle modifiers to their decision-making that ultimately promote extraction of teeth under GA for people with disabilities. Bias training, simulation and post-hoc reflection are examples of recommendations which may be used to improve decision-making in this area.

Medical Diagnoses, Mode of Residence, and Dental Treatment Demand under General Anesthesia in Special Needs Adults in Innsbruck, Austria. A Retrospective Breakdown of Four and a Half Years

Regarding oral/dental care and attendance, special needs individuals depend on their caregivers' commitment. The purpose of this retrospective data analysis of adults who received dental general anesthesia (DGA) in Innsbruck, Austria, was a breakdown of demographic parameters (including the mode of accommodation/care), medical diagnoses (comprising intellectual/physical disablement (IPD) or psychiatric (anxiety) disorders (PDs)), and dental therapy performed under DGA. The sample was composed of 233 consecutive adults who underwent DGA from January 2015 to June 2019. Data were analyzed with descriptive and comparative statistics. In total, 133 (57.1%) subjects were male and 100 (42.9%) female; 176 (75.5%) had IPD and 57 (24.5%) PDs; 168 (72.1%) were living at private and 65 (27.9%) at nursing homes. Median age (IQR) was 35.6 (25.7-47.2) years. In the total sample, 5 (2-9) teeth were restored and 2 (0.5-6.5) teeth were extracted. Individuals with PDs had more teeth restored (p = 0.01) and extracted (p < 0.001) than individuals with IPD. Private home residents had more teeth restored (p < 0.001) but less teeth extracted (p = 0.003) than nursing home residents. Special needs individuals' oral health backlog should be tackled in private and institutional care modalities alike.
