Dental General Anaesthesia Research Articles

The influence of general health on the need for dental general anaesthesia in children.

To analyse the occurrence and causes of dental general anaesthesia (DGA) in healthy and medically compromised children, and to investigate if there are differences between those groups considering factors associated with DGA and DGA procedures. The data was collected from medical records of children under 7years of age treated under DGA in the years 2009 and 2010 at the Oulu University Hospital, Finland. The children were divided into two groups: 0-35-month-olds and≥36-month olds. Background information (year, age, gender, dental diagnosis, health) and the procedures performed were registered. The procedures were analysed considering the child's age and tooth types. The number of children treated under DGA increased between 2009 (58) and 2010 (82), particularly in the group of healthy children. The two main diagnoses leading to DGA were dental caries and dental fear. Dental caries as the first dental diagnosis leading to DGA was more common among the medically compromised children (61.5%) compared to the healthy children (38.6%). The procedures performed were similar among the two groups. However, they varied between the age groups and tooth types and even between upper and lower teeth. The medically compromised children had been treated more frequently under DGA in the past. The threshold for treating medically compromised children under DGA seems to be lower than for healthy children. However, the occurrence of DGA among healthy children has increased recently. To avoid unnecessary DGA, the control of caries should be carried out according to individual needs and independent of whether the child is healthy or has a chronic disease.

Follow-up of children’s oral health-related quality of life after dental general anaesthesia treatment

Objective: Our aim was to analyze longitudinally the impact of young children’s dental general anaesthesia (DGA) treatment on their OHRQoL and to determine their post-operative oral health status at the six-month follow-up together with parental ratings of their children’s oral health.Material and methods: We conducted a prospective follow-up study of OHRQoL among Lithuanian child patients treated under general anaesthesia (n = 144). The study consisted of clinical dental examinations performed by two examiners at the time of DGA and at the six-month recall, along with OHRQoL surveys and data collected from the patients’ files. The dmft index and Silness–Löe plaque index served as clinical measures. The survey tool for assessing the children’s OHRQoL was the previously tested Lithuanian version of the ECOHIS. The Wilcoxon signed-rank test served for the statistical analysis (p < 0.05).Results: The ECOHIS scores clearly decreased post-operatively, indicating a significant (p < 0.001) improvement in the children’s OHRQoL after the DGA treatment. The ECOHIS scores were lower immediately after the DGA treatment and remained low at the six-month recall. Parents rated their child’s oral health as higher after the DGA treatment (p < 0.001). The majority (75%) of the patients had poor or satisfactory oral hygiene at follow-up.Conclusions: This longitudinal study showed a sustained improvement in the children’s OHRQoL six months after their DGA treatment. Post-operative parental ratings of their child’s oral health were higher after the DGA treatment, but the children exhibited insufficient oral hygiene and new caries lesions. An appropriate follow-up system for children receiving DGA treatment with special focus on preventive care is needed.

Development of a decision aid for children faced with the decision to undergo dental treatment with sedation or general anaesthesia.

Decision aids are tools used to help individuals faced with difficult healthcare decisions. They help patients further understand the treatment options available and encourage the sharing of information between patients and clinicians. To develop a decision aid for young patients faced with the decision to undergo dental treatment with inhalation sedation, intravenous sedation, or general anaesthesia (GA). Qualitative interviews with dental patients (aged 10-16 years), and their parents/guardians were used to inform the content of a draft decision aid. Following further revisions, a pilot evaluation of the decision aid was conducted. Patients referred for dental treatment with sedation or GA were recruited from a UK dental hospital. Patients (n = 15) and parents/guardians (n = 13) assigned to the intervention group received the decision aid and routine clinical counselling, whereas patients (n = 17) and parents/guardians (n = 13) in the control group only received routine clinical counselling. Participants completed measures of knowledge, decisional conflict, and dental anxiety. Knowledge scores were significantly higher for participants who received the decision aid when compared to standard care. There were no other significant differences between groups. A decision aid was successfully developed, and initial findings suggest such tools could be beneficial to dental sedation or GA patients and their parents/guardians. Further research is required on the use of such tools in primary care settings, with particular attention to the impact of the decision aid on attendance and completion rates of treatment.

Preventive and invasive treatment in special needs patients: a German retrospective study.

Data on dental treatment of children with special healthcare needs (CSHCN) are sparse. Hence, this study provides information about the changes in the dental condition in a cohort of CSHCN treated in a university dental department in Germany. Patient records of CSHCN treated from January 2004 to December 2012 were screened retrospectively for medical diagnoses (ICD-10) and the type of treatment performed with outpatient dental care (ODC) or general anesthesia (GA). Follow-up data of patients adhering to the recommended recall were recorded, including time and further treatments. A total of 795 CSHCN with a mean age of 6.8years were included. In 41.6% (331/795) of cases, treatment was performed under ODC, and 58.4% (464/795) received GA. Caries experience in CSHCN treated under GA was significantly higher (7.9 d3/4mft/0.9 D3/4MFT) than in ODC (2.5 d3/4mft /0.9 D3/4MFT). Over time, patient flow shifted from invasive (IC) to preventive-based care (PC). Caries-related treatments were most frequent under GA and ODC, though initial caries experience was higher in GA patients. The choice of GA or ODC was statistically independent from the medical condition. This study provides characteristics of a large population of CSHCN treated with and without GA for dental care.

Characteristics of children undergoing dental extractions under general anaesthesia in Wolverhampton: 2007-2012.

Studying characteristics of children requiring extractions under dental general anaesthesia (DGA) can help identify trends, which can be used to facilitate future planning of healthcare services. To report on the profile of children who underwent extractions under DGA between 2007 and 2012 at the New Cross Hospital in Wolverhampton, England.Methods Retrospective analyses of hospital records. Of the 2692 patients seen between 2007 and 2012, 49.6% were boys and 50.4% were girls. The mean age was 7.1 and 7 to 12 years was the largest age group (43%). The majority of the sample was White British (67%). Of the 8,286 teeth extracted, 85% were primary teeth and 15% permanent. More teeth were extracted in boys than girls (P = 0.002) and 'Other' ethnicities had a higher mean number of extractions compared to White British (P <0.001) and South Asians (P = 0.046). The mean age of the patients has decreased over the years (P = 0.001) and the mean number of primary teeth extracted has increased (P = 0.001). A clear dental public health issue has been reinforced through the relatively high level of DGA activity reported. Though rigorous caries prevention remains the ultimate goal, a better assessment and discharge process may help reduce the need for first time DGAs as well as repeats.

Different Aspects of General Anesthesia in Pediatric Dentistry: A Review.

ContextMost child population is able to undergo dental treatment in the conventional setting. However, some children fail to cope with in-office conscious state and cannot respond to usual management modalities. This review aims to discuss the topic further.Evidence AcquisitionA computerized search in databases PubMed, MEDLINE, EMBASE, Google Scholar and Google were performed using dental general anesthesia related keywords. Original and review English-written articles that were limited to child population were retrieved without any limitation of publication date. The suitable papers were selected and carefully studied. A data form designed by author was used to write relevant findings.ResultsPreoperative oral examination and comprehensive evaluation of treatment needs is only possible after clinical and radiographic oral examination. Effective collaboration in dental GA team should be made to minimize psychological trauma of children who undergo dental GA. Before conducting comprehensive dental treatment under GA, the general health of the child and the success rate of procedures provided needs to be accurately evaluated. It is noteworthy that determination of the optimal timing for GA dental operation is of great importance. Providing safety with pediatric dental rehabilitation under GA is critical.ConclusionsBesides criteria for case selection of dental GA, some degree of dental practitioner’s judgment is required to make decision. Pre- and post-operative instructions to parents or caregiver decrease the risk of complications. However, trained resuscitation providers, careful monitoring and advanced equipment minimize adverse outcomes.

Sedation versus general anaesthesia for provision of dental treatment to patients younger than 18 years.

A significant proportion of children have caries requiring restorations or extractions, and some of these children will not accept this treatment under local anaesthetic. Historically this has been managed by the use of a general anaesthetic in children; however, use of sedation may lead to reduced morbidity and cost. The aim of this review was to compare the efficiency of sedation versus general anaesthesia (GA) for provision of dental treatment to children and adolescents younger than 18 years. This review was originally published in 2009 and was updated in 2012 and again in 2015. We will evaluate morbidity and effectiveness of sedation versus GA for provision of dental treatment to patients younger than 18 years. If data become available, we will analyse the cost-effectiveness of different interventions. If data are not available, we will obtain crude estimates of cost.Morbidity can be defined as 'an undesired result or complication'. For the purposes of this review, 'postoperative morbidity' refers to undesired results or complications such as nausea following a procedure, once the patient had been restored to consciousness and could breathe unaided. 'Intraoperative morbidity' refers to any complications that occur during the procedure that may necessitate action by the anaesthetist or the sedationist, such as respiratory arrest. In this updated review, we searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2015, Issue 7); MEDLINE Ovid SP (1950 to July 2015); EMBASE Ovid SP (1974 to July 2015); System for Information on Grey Literature in Europe (SIGLE) (1980 to October July 2012); Latin American & Caribbean Health Sciences Literature (LILACS) (1982 to July 2015); and Institute for Scientific Information (ISI) Web of Science (1945 to July 2015).We also carried out handsearching of relevant journals to July 2015. We imposed no language restriction. We planned to include randomized controlled clinical trials that compared sedative agents versus general anaesthesia in children and adolescents up to 18 years of age undergoing dental treatment. We excluded complex surgical procedures and pseudo-randomized trials. Two review authors assessed titles and abstracts for inclusion in the review. We recorded information relevant to objectives and outcome measures by using a specially designed 'data extraction form'. We will employ the Grades of Recommendation, Assessment, Development and Evaluation Working Group (GRADE) approach to interpret findings. In our original review, we identified 16 studies for potential inclusion after searching available databases and screening titles and abstracts. After retrieving full-text studies, we found none to be eligible. We identified no additional studies in the updated search of July 2012. We identified two studies for possible inclusion in the updated search of July 2015; again we found these to be ineligible. Randomized controlled studies comparing use of dental general anaesthesia versus sedation are needed to quantify differences such as morbidity and cost.

Mothers' perceptions about pediatric dental sedation as an alternative to dental general anesthesia

OBJECTIVE: Moderate sedation has limits in managing children's behavior. Existing literature lacks insight into parental perceptions about the topic. This study aimed to understand mothers' perceptions concerning sedation after their children undergone dental treatment under sedation. METHODS: Twelve mothers and one godmother of 1.3-8.4 year-old children with definitely negative behavior in the dental chair, who had dental treatment under oral sedation, were in depth interviewed according to a semi-structured guide. Responses were analysed using a thematic content method and deductive approach. Two general themes were addressed: "good facet" and "poor facet" of pediatric dental sedation. RESULTS: Analysis of interview transcripts indicated that participants perceived pediatric dental sedation according to two main analytical categories: the "good facet" and the "poor facet". The good facet included advantages of the procedure (e.g. safety, effective behavior management), rapport and completion of the treatment that was initially planned. The poor facet related to limitations of moderate sedation (when child kept struggling) and their own anxiety during the procedure. CONCLUSION: Despite their own stress, mothers were satisfied with this pharmacological method of behavior management.

A Care Pathway for Children Unable to Accept Dental Care Within the General Dental Services Involving the Use of Inhalation Sedation and General Anaesthesia.

Dental treatment is the commonest reason for a child to be in hospital in the UK. This is a shocking statistic for a preventable disease. How can we reduce the high numbers of dental general anaesthetics? It is essential that dental treatment under general anaesthesia (GA) is fully justifiable, ensuring that the right patients receive the right treatment. Guidance for general dental practitioners on when to refer a child for a dental GA is discussed. Treatment planning for this dentally high-risk group of children requires a holistic approach. It is complex and requires an experienced and competent clinical team, including dental care professionals with additional postgraduate qualifications. Often, alternative treatments are successful and a GA can be avoided. An audit of 85 patients referred for GA with Oldham Community Dental Service demonstrated 35% of patients accepted treatment with local anaesthesia only, 25% required inhalation sedation and only 25% were actually referred on for GA. Treatment for this group of patients must include the availability and provision of appropriate alternative treatment modalities, with the right staff and facilities, including those for dental general anaesthetic sessions. Ongoing follow-up within the general dental services is essential for this group of patients.

A study of the provision of hospital based dental General Anaesthetic services for children in the North West of England: Part 2--the views and experience of families and dentists regarding service needs, treatment and prevention.

BackgroundPatterns of service delivery and the organisation of Dental General Anaesthesia (DGA) have been found to differ across hospitals. This paper reports on qualitative research aimed to understand the impact of such variation by exploring views and experiences of families receiving care in different hospital sites, as well as dentists involved in referral and delivery of care.MethodQualitative semi-structured interviews were conducted with 26 people comprising parents (n = 15), dentists working in primary care (n = 6) and operating dentists (n = 5) in relation to DGA. Participants were recruited from areas across the North West of England to ensure a variety referral and treatment experiences were captured. Field notes were made during visits to all settings included in the study and explored alongside interview transcripts to elicit key themes.ResultsA variety of positive and negative impacts on children and parents throughout the referral process and operation day were apparent. Key themes established were clustered around three key topics:Organisational and professional concerns regarding referrals, delivery of treatment and prevention.The role of hospital environment and routine on the emotional experiences of children.The influence of the wider social context on dental health.ConclusionThese findings suggest the need and perceived value of: tailored services for children (such as play specialists) and improved information, such as clear guidance regarding wait times and what is to be expected on the day of the procedure. These features were viewed to be helpful in alleviating the stress and anxiety often associated with DGA. While some elements will always be restricted in part to the hospital setting in which they occur, there are several aspects where best practice could be shared amongst hospitals and, where issues such as wait times have been acknowledged, alternative pathways can be explored in order to address areas which can impact negatively on children.Electronic supplementary materialThe online version of this article (doi:10.1186/s12903-015-0029-3) contains supplementary material, which is available to authorized users.

Issues arising following a referral and subsequent wait for extraction under general anaesthetic: impact on children.

BackgroundUntreated caries in young children can result in a referral for extraction in hospital under general anaesthetic (GA). This study aims to explore the impact of caries during the ensuing wait for GA on children resident in the North West of England.MethodsThe study involved 456 respondents referred to six hospitals in the Northwest of England. Over a two-month period each of these children/ families completed a questionnaire and gave permission to access their referral and consultation notes.ResultsChildren (6.78 years old: 1.50 to 16.42) had on average five teeth extracted (ranging from one to a full clearance, with all teeth removed). Sixty seven per cent of parents reported their child had been in pain, 26% reported schools days being missed and 38% having sleepless nights. The average time from referral to operation was 137 days. Results indicated that children could be in discomfort during their wait, as pain was experienced, on average, 14 days before the operation. Wait time significantly predicated the number of sleepless nights b = .004, t(340) = 2.276, p = .023.ConclusionsIt is clear that pain, sleepless nights and missed school are a feature during a wait for dental GA and can be exacerbated by an extended wait. These data support the need for not only effective prevention of caries within primary care to reduce wait times and experience of GA but also effective management of pain and infection during a prolonged wait for treatment.

Audit of Gross Decay Treatment in Young Children under General Anaesthetic

In Australia, dental caries is one of the most prevalent diseases effecting children. For more severe cases a dental general anaesthetic (GA) is required. A retrospective analysis of clinical records for all patients aged up to 10 years who attended Barwon Health (Geelong, Victoria, Australia) for a dental GA from 2010-2012 was performed. There were 236 separate events in 234 children, with 223 new cases and 11 that had already received a dental GA prior to the study period. The average age of patients at their dental GA procedure was 6.3 ? 2.0 years. Prior to the GA, the average dmft/DMFT was 8 (6-12) (median, interquartile range). The length of time from referral to GA increased significantly from 166.4 days (SD 108.1), 164.3 days (SD 98.9) to225.4 days (SD 129.5) in 2010, 2011 and 2012, respectively. Follow up review appointments after GA appointment was attended by 10.8%, 37.3% and 36.0% of patients, respectively across the same years. Following the findings of long waiting times for GA procedures for children with severe dental caries,and the low rate of attendance for post-GA reviews, a change in dental process is urgently needed.

Tourette syndrome and procedures related to dental treatment: a systematic review.

Dental treatment of patients with Tourette syndrome (TS) may present special challenges to the dentist. The aim was to systematically review the literature regarding perioperative procedures including sedation and general anaesthesia (GA) of patients with TS. Literature searches were performed in PubMed and Embase to identify papers concerning TS in combination with dental treatment, sedation, and/or GA in order to study outcomes regarding co-morbidity, perioperative complications, and drug interactions. The literature search identified six publications (case reports or series) which addressed the topic. No unexpected adverse effects or drug interactions in relation to sedation or GA in TS patients and no perioperative complications were reported. The literature on TS is scarce and the evidence level is low. Therefore, guidelines regarding the dental treatment of patients with TS cannot be formulated at the present time.

Comparison of the children's oral health habits and oral-health-related quality of life following treatment under dental general anesthesia and passive restraint

To compare the children's oral health habits and oral-health-related quality of life following treatment under dental general anesthesia (DGA) and passive restraint (PR). In the Department of Pediatric Dentistry, Peking University School and Hospital of Stomatology, twenty eight 2 to 4-year-old patients treated under DGA and thirty five treated under PR were collected in this non-randomized controlled trial. The general information including age and decayed, missed and filled teeth(dmft), dental plaque index was recorded preoperatively. Two questionnaires, questionnaire of oral health habits and early childhood oral health impact scale (ECOHIS) were completed by parents before and 6 months after treatment (including restoration, root canal treatment, stainless steel crown, tooth extraction, etc.). Six months after treatment, dental plaque index and restoration were reexamined. The patients were significantly elder in DGA group [(3.1 ± 0.6) years old, P < 0.05], and the mean dmft was significantly higher (13.1 ± 4.1, P < 0.001) in DGA group. The postoperative dietary habits and brushing habits significantly improved in PR group, but not in the DGA group. However, according to the results of ECOHIS, the occurrence of pain, the impacts of patients on daily life, psychology and family due to the oral diseases significantly decreased in DGA group (P < 0.05), while in PR group, only the occurrence of pain reduced (P < 0.05). No statistical difference was found between the two groups in new caries or recurrent caries (PR group: 37.1%, DGA group: 39.3%), secondary caries (PR group: 4.1%, DGA group: 2.3%), and failure of the restoration (PR group:1.5%, DGA group: 2.7%). Each behavior management technique has advantages and drawbacks, and no statistical differences were found in the treatment results between the two techniques.

Oral health-related quality of life after dental general anaesthesia treatment among children: a follow-up study.

BackgroundMany young paediatric patients with severe dental caries receive dental treatment under general anaesthesia. Oral health-related quality of life (OHRQoL) can be evaluated to assess the outcome of dental general anaesthesia (DGA) treatment. The aim of our study was to examine the OHRQoL of young Lithuanian children in need of DGA treatment and analyse the impact of DGA treatment on children’s OHRQoL.MethodsWe carried out a prospective clinical follow-up study on OHRQoL among all young Lithuanian child patients who received DGA treatment at the Lithuanian University of Health Sciences Hospital during 2010–2012. The study consisted of clinical dental examinations of patients younger than six years, data collected from their patient files, and an OHRQoL survey completed by their parents prior to the child’s dental treatment. We conducted a follow-up OHRQoL survey one month after the DGA treatment. The Early Childhood Oral Health Impact Scale (ECOHIS) and its effect size (ES) served to evaluate children’s OHRQoL, and the Wilcoxon signed-rank test served for statistical analyses.ResultsWe obtained complete baseline and follow-up data for 140 and 122 participants, respectively (84.7% follow-up rate). Pain and eating problems among children and parents feeling upset and guilty were the most frequently reported impacts at baseline. The parents reported greater impacts on boys than on girls. The ECOHIS score decreased significantly (69.5%, p < 0.001) after DGA treatment, revealing a large ES for the child (1.6) and family (2.4) sections of the ECOHIS.ConclusionsThe OHRQoL of young Lithuanian children requiring DGA treatment is seriously impaired. Dental general anaesthesia treatment results in significant improvement of the children’s OHRQoL. The children’s parents also greatly appreciate this treatment modality for its positive impact on the family’s quality of life.

Improving access to preparatory information for children undergoing general anaesthesia for tooth extraction and their families: study protocol for a Phase III randomized controlled trial

BackgroundChildren can find anaesthesia induction especially distressing and postoperative psychological and physical morbidity are common. Preparation programmes for general anaesthesia (GA) are highly effective in reducing this distress. A Phase II study has already verified the effectiveness of a prototype preoperative GA-coping computer game to help children cope with induction in a dental GA setting. The biggest patient users of pediatric GA services in the UK are children who need to have teeth removed (estimated to be 100,000 yearly). Tooth decay is the most common disease in children worldwide. This study is a Phase III randomized controlled trial (RCT) and will evaluate the effectiveness of the new internet version of this game.Methods/designThe Phase III RCT will use a double-blind three-armed design. The clinical trial will recruit up to 210 children and will compare the web-based game against standard care and another non-medical game. At least 53 patients in each group will be required for 90% statistical power. Distress will be assessed through an evaluation of the child’s behaviour during the visit and later parental reports of physical and psychological morbidity. The satisfaction of parents and children will be measured; the mode of usage of the web-based game will be automatically recorded and the impact on the service (for example, recovery time and throughput) will be reported.The Phase III study primary outcome will measure: (1) patient experience: acceptance of anaesthetic induction, child cooperation and distress, reduction of peri- and postoperative morbidity, child and family satisfaction, and (2) service improvement: anaesthetic time and improvement in throughput. Measures will be administered at baseline, at the time of the GA treatment visit, and at 48 hours and one week postoperatively.DiscussionThis study aims to determine the effectiveness of an online GA-coping game for children and families undergoing tooth extraction under GA.Trial registrationISRCTN18265148 (registered 24 November 2013).

'I felt weird and wobbly.' Child-reported impacts associated with a dental general anaesthetic

This qualitative study sought to obtain children's accounts of having dental extractions under general anaesthesia (GA). The aim was to gain greater understanding of the physical and psychological impacts from a child's perspective. Ten children, aged 6-11 years, maintained a video diary to document their feelings and experiences before, and following their hospital admission. Two semi-structured home interviews supplemented the video diary data and analysis was guided by narrative approaches. This research revealed new insights into children's experiences of having teeth removed under GA. Several of the post-operative impacts correlated with those previously reported by parents/carers. These were notably nausea, bleeding and tiredness, although children used different terminology. However, additional physical and psychological outcomes, both positive and negative, emerged from the children's narratives. Negative aspects included hunger, disturbed eating, being scared/worried and experiencing discomfort from the IV cannula. Interestingly, pain was not a strong theme. Positive outcomes were also reported, such as satisfaction with the resolution of their dental problem and receipt of rewards and attention from family members. These accounts have implications for improving patient experiences and outcomes throughout the dental GA care pathway. A review of pre-operative fasting protocols should be a priority.
