The Effect of Patient-Specific Variables on the Need for Dental Treatment Under General Anesthesia in Children: A Retrospective Study

Aim: For pediatric dentists, meeting the dental treatment needs of young children is often a challenge. Behavioral management techniques may be ineffective in underage children or children with special needs. Therefore, general anesthesia (GA) is required for dental rehabilitation of uncooperative children. The aim of this study was to examine the patient population treated under General Anesthesia (GA) in terms of age, gender, ASA Score (American Society of Anesthesiologists Physical Status Classification System), duration of anesthesia, duration of operation and the presence of systemic diseases of the patients. Material and Methods: In this study, 238 patients aged 2-15 years who underwent dental treatment in the General Anesthesia Operating Room of Selçuk University Faculty of Dentistry were included. Patients were divided into 2 groups according to indications for general anesthesia. Medical health status and ASA scores were analysed. Patients were also evaluated according to age, gender, duration of anesthesia and duration of dental treatment. Results: According to results, the mean age (years) and weight (kg) of the patients were 5,4 and 19,7, respectively. The gender distribution of the patients was 125 female (52,55%) and 113 male (47,5%). The number of ASA I patients was 213 (89,6%) and ASA II patients was 25 (10,5%). In terms of duration of anesthesia, 24 patients were treated in less than 60 minutes (min), 132 patients in 60-120 min and 82 patients in 120-180 min. Conclusion: Dental treatment operating rooms with inpatient services can serve more different patient groups.

Comparison of Total Intravenous Anesthesia with Inhaler Anesthesia in Children Intubated with Remifentanil without Muscle Relaxant

Objective: The effects of remifentanil and muscle relaxant-free intubation as well as total intravenous anesthesia and inhaled anesthesia for tonsillectomy and/or adenoidectomy in children were compared. Materials and Methods: The study was conducted on 80 patients who were to undergo tonsillectomy and/or adenoidectomy between December 2014 and June 2015. Patients were randomized and divided into two groups. In the total intravenous anaesthesia group, 2.5 mg/kg propofol and 2 mcg/kg remifentanil were administered as induction within 90 seconds. In this group, 3 mg/kg/h propofol and 0.5 mcg/kg/min remifentanil were used for maintenance of anesthesia. In the sevoflurane group, 8% sevoflurane and 2 mcg/kg remifentanil were administered as induction within 90 seconds. In this group, 2.5% sevoflurane, 50% nitrogen protoxide and 50% oxygen were used at 6 l/min for maintenance of anesthesia. Results: Peak heart rate and systolic arterial pressure were significantly higher in Group I. Diastolic arterial pressure was significantly higher in Group T at 1 and 2 minutes after intubation and in Group 2 at 10 minutes postoperatively. Mean arterial pressure was higher in Group T at 2 minutes after intubation. In addition, Wong-Baker pain scale and agitation score were significantly higher in Group I. Spontaneous respiration and extubation time were significantly shorter in Group I. There was no difference between the groups in terms of side effects. Conclusion: Group total intravenous anaesthesia was thought to be a better choice in children because it had less impact on postoperative pain, agitation and recovery.

Effectiveness of Local Anesthesia in Children's Pain Perception and Sedation During Dental Procedures Under General Anesthesia—A Randomized Clinical Study

3-Dimensional Virtual Reality Versus 2-Dimensional Video for Distraction During the Induction of Anesthesia in Children to Reduce Anxiety: A Randomized Controlled Trial.

Preoperative anxiety is common in children. It can contribute to negative experiences with anesthetic induction and may cause adverse physiological and psychological effects. Virtual reality (VR) and electronic tablet devices are 2 audiovisual distraction tools that may help to reduce anxiety and enhance the preoperative experience. This study aimed to compare the use of an immersive 3-dimensional (3D) VR to 2-dimensional (2D) video on anxiety in children during induction of general anesthesia. Two hundred children (4-13 years) undergoing elective or emergency surgery under general anesthesia were enrolled in this randomized, controlled trial. Participants were randomized to use either the 3D VR goggles (intervention) or 2D video tablet (control) during anesthetic induction. Anxiety, the primary outcome, was measured using the modified Yale Preoperative Anxiety Scale Short Form (mYPAS-SF) at 2 time points: in the preoperative holding area before randomization (T1) and during induction of general anesthesia (T2). The primary outcome was analyzed using a linear regression model, including demographic and other covariates, to investigate any differences in anxiety scores. Secondary outcomes included evaluating compliance during the anesthetic induction (Induction Compliance Checklist), emergence of delirium (Cornell Assessment of Pediatric Delirium), perceived usefulness of the device, and child satisfaction. Participant characteristics were similar between the 3D VR (n = 98) and 2D video (n = 90) groups, with a mean (±standard deviation) age 8. 8 ± 2.8 years. The median (lower quartile, upper quartile) mYPAS-SF scores for the 3D VR group at the preoperative holding area were 22.9 (22.9, 35.4), then 29.2 (24.0, 41.7) during induction. For the 2D Video group, the scores were 27.1 (22.9, 35.4) and then 30.2 (22.9, 41.1). No significant difference was observed in the increase in mYPAS-SF scores between groups (P = .672). Children in the 3D VR group were less likely to be rated as having a perfect induction (P = .039). There was no evidence of a difference between the groups in emergence delirium. Both devices were rated highly for usefulness and patient satisfaction. Children preferred VR, while anesthesiologists and parents felt the 2D was more useful. This randomized controlled trial demonstrated that preoperative anxiety was equally low and induction compliance high with both 3D VR and 2D video distraction in children with parental presence during anesthetic induction.

Assessing Residual Gastric Fluid Volume after Administering Diluted Oral Contrast until One Hour Prior to Anesthesia in Children: An Observational Cohort Study.

Background: Gastric fluid volume has been used as a surrogate marker for pulmonary aspiration risk in studies evaluating fasting protocol safety. This study measured residual gastric fluid volume in children using a protocol in which diluted oral contrast medium was administered up until one hour before anesthesia. Methods: This was a single-center prospective observational cohort trial of 70 children for elective abdominal/pelvic computed tomography (CT). Imaging was performed after diluted enteral contrast medium administration, beginning two hours before and ending at least one hour before induction. For each patient, gastric fluid volume was calculated using an image region of interest. The primary outcome measure was gastric fluid volume measured using the computed tomography image. Results: The median time from the end of contrast administration to imaging was 1.5 h (range: 1.1 to 2.2 h). Residual gastric volume, measured using CT was <0.4 mL/Kg in 33%; ≥0.4 mL/Kg in 67%; and ≥1.5 mL/Kg in 44% of patients. Residual gastric volumes measured using CT and aspiration were moderately correlated (Spearman's correlation coefficient = 0.41, p = 0.0003). However, the median residual gastric volume measured using CT (1.17, IQR: 0.22 to 2.38 mL/Kg) was higher than that of aspiration (0.51, IQR: 0 to 1.58 mL/Kg, p = 0.0008 on differences in paired measures). Three cases of vomiting were reported. No evidence of pulmonary aspiration was identified. Conclusions: Children who receive large quantities of clear fluid up to one hour before anesthesia can have a significant gastric residual volume.

Comparative analysis of the effects of bronchial intubation and bronchial blocker on the outcomes of thoracoscopic surgery in infants and small children

Objective: To compare the effects of bronchial intubation and blocker on the outcomes of thoracoscopic surgery in infants and small children. Methods: A total of 387 children, including 210 males and 177 females, aged (17.5±8.3) months, who underwent elective thoracoscopic surgery under general anesthesia in Children's Hospital Affiliated to Capital Institute of Pediatrics from January 2019 to August 2023 were retrospectively analyzed. The children were divided into bronchial intubation group and bronchial blocker group according to the intraoperative single-lung ventilation mode. After matching the age factor using the propensity score matching with nearest neighbor matching method, 258 cases were finally included in the bronchial intubation group, and 129 cases were included in the bronchial blocker group. The primary outcome was the incidence of postoperative pulmonary complications in two groups. The secondary outcomes included the incidence of intraoperative hypoxemia, postoperative oxygenation index, postoperative extubation time, the length of postoperative hospitalization and the total medical expenses during hospitalization between the two groups. Results: The incidence of postoperative pulmonary complications in the bronchial intubation group and bronchial blocker group was 15.5% (40/258) and 12.4% (16/129), the incidence of intraoperative hypoxemia was 20.2% (52/258) and 16.3% (21/129), the postoperative oxygen indexes were 306 (269, 323) and 311 (274, 336) mmHg (1 mmHg=0.133 kPa), the extubation time was (9.2±4.5) and (8.9±4.2) min, the length of postoperative hospitalization was (5.5±0.6) and (5.5±0.5) days and the total medical expenses were (34±6) and (35±6) thousand yuan, with no statistically significant differences between the two groups (all P>0.05). Conclusion: Both bronchial intubation and blocker can be used for one lung ventilation in thoracoscopic surgery for infants and small children, without affecting the postoperative outcomes.

Pre-school children single inhalation anesthetic exposure and neuro-psychological development: a prospective study and Mendelian randomization analysis.

For children who are unable to cooperate due to severe dental anxiety (DA), dental treatment of childhood caries under Dental General Anesthesia (DGA) is a safe and high-quality treatment method. This study aims to evaluate the impact on neurocognitive functions and the growth and development of children 2 years after dental procedure based on previous research, and further establish a causal relationship between general anesthesia (GA) and changes in children's neurocognitive functions by incorporating Mendelian Randomization (MR) analysis. Data were collected and analyzed from 340 cases of S-ECC procedures of preschool children conducted in 2019. This involved comparing the neurocognitive outcomes 2 years post-operation of preschool children receiving dental procedures under general anesthesia or local anesthesia. Physical development indicators such as height, weight, and body mass index (BMI) of children were also compared at baseline, half a year post-operation, and 2 years post-operation. We performed a Mendelian randomization analysis on the causal relationship between children's cognitive development and general anesthesia, drawing on a large-scale meta-analysis of GWAS for anesthesia, including multiple general anesthesia datasets. Outcome data were obtained for 111 children in the general anesthesia group and 121 children in the local anesthesia group. The mean FSIQ score for the general anesthesia group was 106.77 (SD 6.96), while the mean score for the local anesthesia group was 106.36 (SD 5.88). FSIQ scores were equivalent between the two groups. The incidence of malnutrition in children in the general anesthesia group was 27.93% (p < 0.001) before surgery and decreased to 15.32% (p > 0.05) after 2 years, which was not different from the general population. The IVW method suggested that the causal estimate (p = 0.99 > 0.05, OR = 1.04, 95% CI = 5.98 × 10-4-1.82 × 103) was not statistically significant for disease prevalence. This indicates no genetic cause-and-effect relationship between anesthesia and childhood intelligence. There were no adverse outcomes in neurocognitive development in 2 years after severe early childhood caries (S-ECC) procedure under total sevoflurane-inhalation in preschool children. The malnutrition condition in children can be improved after S-ECC procedure under general anesthesia. Limited MR evidence does not support a correlation between genetic susceptibility to anesthesia and an increased risk for intelligence in children.

Postoperative Morbidity after Dental Treatment under General Anesthesia in Children with and without Disabilities.

Background and Objectives: General anesthesia induces reversible unconsciousness, eliminating sensation and enabling painless medical procedures. Vital for dental care, it addresses patients with medical conditions, those needing extensive procedures, and those unable to cooperate due to fear. Dental care for patients with disabilities is a significant unmet need, with studies showing increased oral disease prevalence. This research aims to analyze postoperative morbidity both in healthy and disabled children undergoing dental procedures under general anesthesia. Materials and Methods: This study involved 96 children aged 3 to 15 with dental caries. Two groups were formed: the control group (CTL) (52.94%) included healthy patients requiring general anesthesia due to unsatisfactory cooperation, and the other group included children with physical or intellectual disabilities (CD) (47.96%). Postoperative complications were monitored 1 h after the procedure and 1, 3, 7, and 14 days after the procedure by contacting parents/caregivers by phone. The intensity of postoperative pain was assessed using the Wong-Baker faces pain rating scale. General anesthesia was conducted following a standardized protocol for dental procedures. Results: CTL patients complained more often about postoperative pain 1 h after the procedure (p = 0.03). One day after the procedure, oral bleeding (p = 0.04), fever (p = 0.009), and diarrhea (p = 0.037) occurred more often in CD. In the same period, sore throat appeared more often in CTL (p = 0.036). Three days after the dental treatment, there were statistically significant increases in the occurrence of agitation (p = 0.043) and constipation (p = 0.043) in CD. Seven days later, CD demonstrated a higher occurrence of agitation (p = 0.037). According to the Wong-Baker faces pain rating scale, CTL experienced more frequent and intense pain. Conclusions: CD more frequently reported complications like oral bleeding, fever, and diarrhea. In contrast, the CTL group more often reported pain-related symptoms. The conclusion underscores the need for a pain control protocol for CD and emphasizes the importance of frequent monitoring to prevent unwanted consequences during tooth restoration under general anesthesia.

Organization and Implementation of Patient-Centered Anesthesia in Children in Terms of the Surgical Department in the Multidisciplinary Hospital

Providing medical care based on a patient-centered medicine model supposes close collaboration with patients and their families based on partnership. The development of action plan aimed on implementation of comfortable conditions for the child during surgery and anesthesia, considering his needs and age characteristics, is a topical issue in pediatrics. This article provides an organizational model for anesthesia in child-friendly environment and covers all the main stages of the patient's stay in the hospital.

Evaluation of Postoperative Discomfort After Strabismus Surgery Under General Anesthesia in Children: A Prospective Observational Study.

Strabismus surgery is most commonly performed on children under general anesthesia. However, few studies have focused on the postoperative discomfort in children after strabismus surgery. This study aimed to evaluate postoperative discomfort and the associated risk factors in children who underwent strabismus surgery under general anesthesia. A single-center prospective observational study including 300 children who underwent strabismus surgery after general anesthesia was conducted. Patients' characteristics, preoperative anxiety, surgical and anesthesia data, discomfort within 24 hours after postanesthesia care unit were recorded. The primary outcome was the incidence of postoperative discomfort. Approximately 51.33% of the children complained of at least one of the following types of postoperative discomfort: postoperative nausea and vomiting (PONV) (23.00%), headache (4.33%), dizziness (20.33%) and emergence agitation (EA) (5.33%). Multivariate analysis indicated that history of motion sickness (P<0.001, odds ratio [OR]=3.72), and surgery in the dominant eye (P=0.010, OR=2.00) were independent predictors of postoperative discomfort; age was an independent predictor of EA (P<0.001, OR=0.36); prism diopter≥40 was an independent predictor of headache (P=0.005, OR=5.53); age (P=0.020, OR=1.12) and history of motion sickness (P=0.001, OR=2.80) were independent predictors of dizziness; history of motion sickness (P=0.001, OR=2.63) and surgery of inferior oblique anterior transposition (IOAT) (P=0.004, OR=3.10) were independent predictors of PONV. The most frequent postoperative symptoms in children after undergoing strabismus surgery under general anesthesia are PONV, dizziness, EA, and headache. Younger age, larger angle of strabismus, history of motion sickness, surgery on the dominant eye, and surgery of IOAT may be additional risk factors for postoperative discomfort.

Children's Anaesthesia and perioperative care challenges, and innovations

The 2015 Sustainable Development Goals emphasise good health to all with reduced inequalities, and surgical and anaesthesia care is essential to achieve these. https://sdgs.un.org/goals. However, it has been estimated that 1.7 billion children do not have access to safe anaesthesia and surgery when needed and this disproportionately affects children in low- and middle-income countries (1). It is alarming that 1 in 10 individuals in LMICs do not have access to safe surgical care. Both safe surgery and anaesthesia are essential for ensuring that individuals receive proper medical attention. Economically viable public health initiatives that can avert many disability-adjusted years are needed. (2–4)Morbidity and mortality from surgical disease and anaesthesia care remain high in low-income countries, unlike in high-income countries. The incidence of severe anaesthesia-related critical events and perioperative cardiac arrest is between three and ten times more in LMICs than in HICs (5–7) A baseline POMR that is 100 times higher in LMICs compared to HICs is reported. (8) This perioperative morbidity and mortality gap is more evident in neonates and younger age groups, especially in children with congenital abnormalities. The challenges facing providers of anaesthesia and perioperative care are multifactorial and include but are not limited to the inadequate workforce, inadequate and inappropriate infrastructure, lack of adequate and appropriately sized equipment, including monitors, and safe monitoring capacity, supply chain challenges for medicines and reusable consumables, unreliable supply of oxygen and blood products, lack of data and research for policy formulation, inadequate resource allocation from governments and lack of safety culture among other things. In paediatrics, this is further multiplied by the variability in the sizes of the patients, from neonates to older children (9).1.Improved perioperative care must include anaesthesia and nursing to improve perioperative outcomes for children.2.Perioperative care for children in LMICs is predominantly by non-physician anaesthesia providers or non-specialty-trained anaesthesiologists.3.There is a need to train physician anaesthesia leaders to direct and oversee the care of children undergoing anaesthesia4.Infrastructure and equipment for the safe provision of paediatric anaesthesia/perioperative care are usually wanting/often times inadequate and inappropriate.5.The GICS OReCS document provides a valuable guide for the bare minimum requirements for the provision of safe paediatric anaesthetic and surgical care services, starting at the district hospital.6.Equipment donations should be conscientious, in consultation with local leads. Considerations will include biomedical support for maintenance, availability of spare parts, and electrical compatibility, among others.7.Context-specific innovations have been shown to work in LMICs and include paediatric anaesthesia courses for all providers and simulation-based training using low technology.8.Any worthwhile programs aimed at improving anaesthetic and surgical care for children need to ultimately fit into national healthcare systems.

Reversal of Rocuronium-Induced Neuromuscular Blockade by Sugammadex Under Sevoflurane and Desflurane Anesthesia in Children.

In children, neuromuscular blockers may have different effects with various inhalation agents and incomplete reversal of the blockade continues to be a problem. The aim of the study is to observe the effects of sugammadex on reversing the blockade by a single dose of rocuronium, the peak inspiratory pressure, hemodynamic parameters in children under sevoflurane and desflurane anesthesia. One hundred forty-eight children aged 2-10 years old, to be operated under shortterm general anesthesia, were enrolled in this prospective randomized controlled trial. After induction, the patients were intubated at the end of TOF (Train-of-four) ratio of 1.0-0. The time taken until TOF reached 0.25 was recorded, and 2 mg/kg sugammadex was administered to the patients. The period until the TOF was at least 0.9 and in the first 10 minutes after sugammadex injection, peak inspiratory pressure, the systolic-diastolic arterial pressure, and the heart rate were monitored and possible side effects were observed in the recovery room. Following the injection of sugammadex, the time taken for TOF of 0.25 to reach >0.9 was significantly shorter in the 2-4-year-old age group under sevoflurane anesthesia. After sugammadex injection, a small but statistically significant increase in peak inspiratory pressure values was observed in Group D at the 2nd, 5th, and 10th minutes. Rapid and complete recovery was achieved from the block induced by a single dose of 0.6 mg/ kg rocuronium by the use of sugammadex which did not give rise to any side effects.

The eXpectations of Parents regarding Anesthesiology Study (XPAS) from a parental perspective: a two-phase observational cross-sectional cohort study.

Uncertainty concerning anesthetic procedures and risks in children requiring anesthesia may cause concerns in parents and caregivers. To explore parental expectations and experiences regarding their child's anesthesia using questionnaires designed with parental input. This observational cross-sectional cohort study included parents (including caregivers) of children undergoing anesthesia in a tertiary pediatric referral university hospital. The study consisted of two phases. In Phase 1, we developed three questionnaires with parental involvement through a focus group discussion and individual interviews. The questionnaires focused on parental satisfaction, knowledge, concerns, and need for preparation regarding their child's anesthesia. In Phase 2, independent samples of parents completed the questionnaires at three time points: before the preanesthesia assessment (T1), 2 days after the preanesthesia assessment (T2), and 4 days after the anesthetic procedure (T3). In Phase 1, 22 parents were involved in the development of the questionnaires. The three questionnaires contained 43 questions in total, of which 10 had been proposed by parents. In Phase 2, 78% (474 out of 934) parents participated at T1, 36% (610 out of 1705), at T2 and 34% (546 out of 1622) at T3. Parental satisfaction scores were rated on a visual analogue scale for the preanesthesia assessment with a median of 87/100, and with a median of 90/100 for the anesthetic procedure (0: not satisfied and 100: satisfied). Parental concerns were rated with a median of 50/100 (0: no concerns and 100: extremely concerned). Parental answers from the questionnaire at T2 revealed significant knowledge deficits, with only 73% reporting that the anesthesiologist was a physician. Parents preferred to receive more information about the procedure, especially regarding the intended effects and side effects of anesthesia. Overall, parental satisfaction scores regarding the pediatric anesthesiology procedure were high, with a minority expressing concerns. Parents indicated a preference for their child's anesthesiologist to visit them both before and after the anesthetic procedure. Parental expectations regarding anesthesia did not completely correspond with the information provided; more information from the clinician about the intended effects and side effects of anesthesia was desired.

The Effect of Low Dose Nalbuphine or Ketamine in the Prevention of Emergence Agitation after Sevoflurane Anesthesia in Children Undergoing Tonsillectomy with or without Adenoidectomy

Abstract Background Emergence agitation (EA) in children is increased after sevoflurane anesthesia. Nalbuphine and midazolam have been used for prophylactic treatment with controversial results. Patients and Methods Totally, 90 children between 4 and 10 years of age and of American Society of Anesthesiologists I-II undergoing adenotonsillectomy under sevoflurane-based anesthesia were enrolled in the study. Children were randomly allocated to one of the three groups: group N received nalbuphine 0.1 mg/kg, group K received ketamine 0.25 mg /kg and group S received the equivalent volume saline. The study medications will be given after discontinuation of sevoflurane by the end of surgery. In the post anesthesia care unit EA was assessed with emergence agitation scale upon admission (T0), after 5 min (T5), 10 min (T10), 15 min (T15), 20 min (T20), 25 min (T25) and 30 min (T30). Results In the PACU, the incidence of EA (emergence agitation scale) were significantly lower in the N Group (6.6%) and K Group (16.6%) compared to S group (33%) with (p = 0.044), the duration in PACU was significantly prolonged in S group compared to K group and N group (p- value 0.011), more patients experienced postoperative pain (mCHEOPS) in S group compared to N group and K group ( p-value 0.001). Conclusion Nalbuphine 0.1 mg/kg or ketamine 0.25 mg/kg are effective in preventing emergence agitation following sevoflurane-anesthetized adenotonsillectomy paediatric patients.

General Anesthesia in Children with Dental Diseases from Parents’ Perspective: A Cross-sectional Observational Study

Risk Factors of Hypoxemia in the Postanesthesia Care Unit After General Anesthesia in Children

PurposeTo investigate the incidence and risk factors of hypoxemia in the postanesthesia care unit (PACU) after general anesthesia in children. DesignA retrospective observational study. MethodsElective surgical patients (N = 3,840 patients) treated in a pediatric hospital were divided into a hypoxemia group and a nonhypoxemia group according to the presence of hypoxemia following transport to the PACU. The clinical data of the 3,840 patients were compared between these two groups to evaluate factors that were linked to the development of postoperative hypoxemia. Factors that showed a statistically significant difference (P < .05) in single-factor tests were then examined in multivariate regression analyses to identify hypoxemia risk factors. FindingsIn our study group of 3,840 patients, 167 (4.35%) patients developed hypoxemia, with an incidence of 4.35%. Univariate analysis indicated that age, weight, anesthesia method, and operation type were significantly associated with hypoxemia. Logistic regression analysis indicated that operation type was associated with hypoxemia. ConclusionsSurgery type is a primary risk factor for pediatric hypoxemia in the PACU following general anesthesia. Patients undergoing oral surgery are more prone to hypoxemia and should be more intensively monitored to ensure timely treatment if required.

Remimazolam as an Adjunct to General Anesthesia in Children: Adverse Events and Outcomes in a Large Cohort of 418 Cases.

Remimazolam was first approved in 2020 as a general anesthetic for adults and still does not have pediatric labeling. Our study will be the first pilot program that administers remimazolam as an adjunct to a general endotracheal anesthetic in children. Between August 2020 and December 2022, electronic medical records were collected for all children who received remimazolam during anesthesia. The remimazolam dosing regimen was extrapolated from the adult package insert, with intravenous induction doses of 12 mg/kg/h administered until the desired effect was achieved. Subsequent infusions were given at a rate of 1-2 mg/kg/h, accompanied by intermittent boluses of 0.2 mg/kg, with all dosing adjustments made according to the anesthesiologist's clinical discretion. A total of 418 children (mean 4.6 yrs, 68.7% ASA 1 and 2) underwent surgeries which averaged 81.2 min. A total of 75.2% of patients had greater than a 20% change (increase or decrease) in MAP (lowest or highest) from baseline, and 203 (49.3%) patients had greater than a 30% change (increase or decrease) in MAP (lowest or highest) from baseline. A total of 5% received ephedrine to treat unanticipated hemodynamic variability. Discharge criteria were met within an average of 13.8 min after arrival at the post-anesthesia care unit. Remimazolam may offer the benefits of rapid recovery following general endotracheal anesthesia. The risk of hemodynamic variability which necessitates and responds to ephedrine should be anticipated.

Multiple General Anesthesia in Children: A Systematic Review of Its Effect on Neurodevelopment.

The effect of multiple general anesthesia (mGA) procedures administered in early life is a critical theme and has led the Food and Drug Administration (FDA) to issue an alert. This systematic review seeks to explore the potential effects on neurodevelopment of mGA on patients under 4 years. The Medline, Embase and Web of Science databases were searched for publications up to 31 March 2021. The databases were searched for publications regarding "children multiple general anesthesia OR pediatric multiple general anesthesia". Case reports, animal studies and expert opinions were excluded. Systematic reviews were not included, but they were screened to identify any possible additional information. A total of 3156 studies were identified. After removing the duplicates, screening the remaining records and analyzing the systematic reviews' bibliography, 10 studies were considered suitable for inclusion. Comprehensively, a total cohort of 264.759 unexposed children and 11.027 exposed children were assessed for neurodevelopmental outcomes. Only one paper did not find any statistically significant difference between exposed and unexposed children in terms of neurodevelopmental alterations. Controlled studies on mGA administered before 4 years of age support that there might be a greater risk of neurodevelopmental delay in children receiving mGA, warranting the need for careful risk/benefit considerations.

Effects of Pharmacological Intervention on Recovery After Sevoflurane Anesthesia in Children: a Network Meta-analysis of Randomized Controlled Trials.

Sevoflurane, commonly administered to children as anesthesia, often leads to emergence delirium (ED). Currently, a consensus is lacking among clinicians regarding pharmacological interventions to improve recovery. To determine an effective approach, we compared the effects of several drugs in lowering the incidence of ED after sevoflurane anesthesia in children.We searched online databases for relevant randomized controlled trials (59 studies selected; 5199 NMA-eligible participants) and performed a frequentist network meta-analysis (NMA). This study was registered on PROSPERO (number CRD: 42022329939).All included studies had a low to moderate risk of overall bias. The incidence of ED after sevoflurane anesthesia in children differed according to other drugs administered, and were ranked from high to low according to the surface under the cumulative ranking curve (SUCRA).Sufentanil (91.2%) and dexmedetomidine (77.6%) were more likely to reduce the incidence (SUCRA value) of ED, whereas the placebo (6.5%), ramelteon (11.1%), and magnesium (18%) were less likely to reduce the incidence of ED. Remifentanil (89.3%) ranked first in shortening emergence time, followed by placebo (82.4%) and ketamine (69.7%). Placebo shortened extubation time, followed by remifentanil (66.5%) and alfentanil (61.4%).Sufentanil and remifentanil lowered sevoflurane-induced ED incidences among children and shortened the emergence time more effectively than other drugs. Most adjuvant drugs that are combined with sevoflurane either do not change or may even prolong extubation time. Further research and clinical trials are required to support and update these conclusions.

Trends of Dental Treatment under General Anesthesia and Patterns of Repeated General Anesthesia in Children and Adolescents with Severe Disabilities

The aim of this retrospective study was to evaluate the demographic characteristics of pediatric dental patients who underwent dental treatment under general anesthesia (DTGA) at the Seoul National University Dental Hospital from January 2011 through December 2020 and compare the patterns of repeated DTGA between dental patients with severe disabilities (DSD) and non-DSD (healthy or medically compromised patients without DSD). There were 1,857 DTGAs among 1,719 patients (mean age = 5.1 years; males = 59.3%; ASA 2 or above = 52.9%; DSD = 26.8%). Overall, 6.6% of patients underwent repeated DTGA, and the rate of repeated DTGA over a 10-year period was 7.4%. ASA 2 or above (&lt;i&gt;p&lt;/i&gt; &lt; 0.0001) and DSD (&lt;i&gt;p&lt;/i&gt; &lt; 0.0001) were more likely to undergo repeated DRGA compared to ASA 1 and non-DSD. At both GA1 and GA2, DSD received significantly more restorative treatment on permanent teeth than non-DSD (&lt;i&gt;p&lt;/i&gt; = 0.002, &lt;i&gt;p&lt;/i&gt; &lt; 0.0001, respectively). There has been an increasing demand for DTGA in pediatric dentistry over the last 10 years. Regular check-ups and preventive oral health care are necessary for pediatric dental patients with severe disabilities to reduce the possibility of repeated DTGA.
