    摘要：The aim of this study was to compare the efficacy of articaine versus lidocaine, both containing epinephrine, using a single buccal infiltration for extraction of primary molars.A total of 100 children requiring primary molar extraction received buccal infiltration using either 4% articaine or 2% lidocaine, both with epinephrine, with 50 children in each group. The Wong-Baker Facial Pain Scale (FPS) was used to evaluate pain perception subjectively. The heart rate and the blood pressure values were assessed objectively as an indirect measure of physiological pain perception. The Wilcoxon-Mann-Whitney test was used for comparing mean pain scores, heart rate, and blood pressure in both the groups. Single buccal infiltration with articaine was sufficient for achieving palatal or lingual anesthesia in all the children receiving it while all children in the lidocaine group required supplemental anesthesia. The mean FPS value was found to be higher in lidocaine group and was statistically significant. The mean heart rate recorded during the intervention was less than the mean baseline values in the articaine group, which was found to be statistically significant. For pediatric patients age 7 to 12 years, single buccal infiltration with 4% articaine with 1:100,000 epinephrine is more effective compared to 2% lidocaine with 1:80,000 epinephrine for primarly molar extraction.

    摘要：An estimation of the appropriate tubing depth for fixation is helpful to prevent inadvertent endobronchial intubation and prolapse of cuff from the vocal cord. A feasible estimation formula should be established. We measured the anatomical length of the upper-airway tract through the oral and nasal pathways on cephalometric radiographs and tried to establish the estimation formula from the height of the patient. The oral upper-airway tract was measured from the tip of the incisor to the vocal cord. The nasal upper-airway tract was measured from the tip of the nostril to the vocal cord. The tracts were smoothly traced by using software. The length of the oral upper-airway tract was 13.2 ± 0.8 cm, and the nasal upper-airway tract was 16.1 ± 0.9 cm. We found no gender difference (p > .05). The correlations between the patients' height and the length of the oral and nasal upper-airway tracts were 0.692 and 0.760, respectively. We found that the formulas (height/10) − 3 (in cm) for oral upper-airway and (height/10) + 1 (in cm) for nasal upper-airway tract are the simple fit estimation formulas. The average error and standard deviation of the estimated values from the measured values were 0.50 ± 0.66 cm for the oral tract and 0.39 ± 0.63 cm for the nasal tract. Thus, considering the length of the intubation marker of each product (DM), we would like to propose the length of tube fixation as (height/10) + 1 + DM for nasal intubation and (height/10) − 3 + DM for oral intubation. In conclusion, the estimation formulas of (height/10) − 3 + DM and (height/10) + 1 + DM for oral and nasal intubation, respectively, are within almost 1 cm error in most cases.

    摘要：The purpose of this study was to determine anesthetic success in adjacent teeth following a primary infiltration of the maxillary lateral incisor and first molar using 1.8 mL of 2% lidocaine with 1:100,000 epinephrine. Three hundred eight asymptomatic subjects received an infiltration of a cartridge of 2% lidocaine with 1:100,000 epinephrine over the maxillary lateral incisor (163 subjects) or first molar (145 subjects). Pulpal anesthesia of the injected tooth and adjacent mesial and distal teeth was monitored with the electric pulp tester in 2-minute cycles for a total of 60 minutes. No response from the subject at the maximum output (80 reading) of the pulp tester was used as the criterion for pulpal anesthesia. Comparisons of the odds of pulpal anesthesia (defined as an 80/80 response to electric pulp testing over 60 minutes) between the experimentally injected tooth and adjacent teeth were analyzed using mixed-models, repeated-measures logistic regression. When compared with the lateral incisor infiltration, the adjacent mesial tooth (central incisor) and distal tooth (canine) achieved statistically lower anesthetic success. When compared with the first molar, the mesial tooth (second premolar) did not differ statistically. However, significant differences were shown between the first molar and the second molar, with the distal tooth (second molar) achieving a statistically higher rate of pulpal anesthesia, which was related to a better duration of anesthesia. For asymptomatic patients, local anesthesia of the adjacent mesial (central incisor) and distal (canine) teeth to the infiltrated lateral incisor had lower pulpal anesthetic success. Because standard infiltration anesthesia of the lateral incisor is of short duration, repeating the infiltration at 30 minutes will result in a high incidence of pulpal anesthesia for 60 minutes. Local anesthesia of the adjacent distal tooth to the first molar (second molar) had a statistically higher rate of total pulpal anesthesia than the infiltrated first molar due to the longer duration of pulpal anesthesia. However, if pulpal anesthesia is required for 60 minutes in the first and second molars, the clinician may need to add an additional infiltration to ensure anesthesia.

    摘要：The location of the mandibular foramen (MF) on digital panoramic radiographs can be an important guide for clinicians when administering the inferior alveolar nerve block (IANB) for dental anesthesia of the mandible. This study, aimed to assess the location of the MF relative to the anterior border (AB) of the ramus and the occlusal plane (OP) from digital panoramic radiographs. An observational case series study was conducted on digital panoramic radiographs from the oral and maxillofacial radiology department archives of patients at least 18 years of age with a 1:1 scale (100%). The samples had to have at least 2 lower molar teeth on both sides without any blurring, previous fracture of the ramus or other artifacts. The distance of the MF to the OP and the AB of the ramus was measured using a caliper. The role of age and gender were also analyzed statistically using the 2-way analysis of variance test. One hundred ninety-four digital panoramic radiographs were included in the analysis. The findings showed that the vertical distance of the MF to the OP was a maximum of 14.52 mm and a minimum of −3.0 mm (mean 4.32 ± 2.34 mm). The distance of the MF to the AB of the ramus was a maximum of 25.52 and a minimum 9.68 mm (mean 16.48 ± 3.28 mm). Based on these findings, the IANB target site for injection should be approximately 5 mm above the OP and approximately 16.5 mm beyond the AB of the ramus to achieve successful anesthesia of the mandible via standard IANB in an Iranian population.

    摘要：This study aims to compare the effect of topical anesthesia against the use of no topical agent on pain of needle penetration and local anesthesia deposition during buccal infiltration in anterior maxilla. In a randomized controlled trial, 100 adult participants were randomly allocated to the benzocaine group (received 20% benzocaine gel) and no benzocaine group (received no topical agent) prior to buccal infiltration in maxillary anterior teeth. A 27-gauge needle was used to deposit 2% lidocaine with 1:100,000 epinephrine. Pain of needle penetration and local anesthesia deposition was recorded separately using an 11-point Numeric Pain Rating Scale. Results showed that although 20% benzocaine significantly reduced pain on needle penetration during buccal infiltration in maxillary anterior teeth, the difference was small and the clinical significance is not clear. Topical anesthetic did not affect pain of local anesthetic deposition.

    摘要：Hereditary angioedema (HAE) is a rare genetic disease that results from deficiency or dysfunction of C1 inhibitor (C1-INH). This disease is characterized by sudden attacks of angioedema. When edema occurs in the pharynx or larynx, it can lead to serious airway compromise, including death. Physical and/or psychological stress can trigger an attack. Dental treatment, including tooth extraction, is also a recognized trigger. We report a case of a 20-year-old male with HAE who required impacted third molar extractions. C1-INH concentrate was administered 1 hour before surgery, which was completed under deep intravenous sedation. This report describes the anesthetic management of a patient with HAE and reviews treatment options and concerns.

    摘要：A 26-year-old woman with a history of feeling nauseated during dental local anesthesia presented to our clinic for tooth extraction under intravenous sedation. Although she had experienced episodes of neurally-mediated syncope, her symptoms were controlled well with drug therapy, stopped 3 years earlier. No syncope episodes developed over the previous 2 years. Tooth extraction was performed under intravenous sedation without incident. When she was returned to a sitting position after being roused, convulsion, loss of consciousness, and cardiac arrest developed. One week later, similar symptoms occurred immediately after suture removal. We suspect that the change in body position triggered these episodes. It is important to avoid abrupt changes in body position and any other triggers and to administer preventive drugs in patients at high risk of syncope.

    【2hr】Intravenous Sedation in Arnold-Chiari Malformation With Respiratory Failure

    机译 患有呼吸衰竭的Arnold-Chiari畸形的静脉镇静
    摘要：Type II Arnold-Chiari malformation (ACM) is an abnormality in which the cerebellum, pons, and medulla oblongata are displaced downward into the spinal cord. Type II ACM is often complicated by respiratory depression, sleep-disordered breathing, and deglutition disorder as a result of medullary dysfunction and impairment of the lower cranial nerves. Bending and stretching of the neck is restricted, and anesthetic management is problematic in patients with the disorder. We performed dental treatment twice under intravenous sedation in a patient with intellectual disability with type II ACM complicated by hypercapnic respiratory failure. Propofol was used for the first sedation procedure. Repeated bouts of respiratory depression occurred on that occasion, so the airway was managed manually by lifting the jaw. However, aspiration pneumonitis occurred postoperatively. A combination of dexmedetomidine and midazolam was used for sedation on the second occasion, and the intervention was completed uneventfully without any respiratory depression. Our experience with this patient highlights the need for selection of an agent for intravenous sedation that does not require neck extension and has minimal effect on respiration in patients with type II ACM, who are at high risk of respiratory depression and pulmonary aspiration.

    摘要：We report a case of difficult endotracheal intubation in a patient with Treacher Collins syndrome. A sixteen-year-old female patient scheduled for general anesthesia had a displaced palatal tooth that interfered with laryngoscope insertion into the pharyngeal space. To address this problem, we successfully performed endotracheal intubation using a fiberscope while elevating the epiglottic vallecula using a King Vision™ video laryngoscope. A later operation was performed after tooth extraction without difficult laryngoscopy. Our experience stresses the importance of removing obstructions to laryngoscopic inspection prior to general anesthesia.

    【2hr】Office-Based Sedation/General Anesthesia for COPD Patients, Part II

    包量

    机译 针对COPD患者的基于办公室的镇静/全身麻醉，第二部分
    摘要：The safe treatment of patients with chronic obstructive pulmonary disease (COPD) in dental office office-based settings can be quite complex without a current understanding of the etiology, course, severity, and current treatment modalities of the disease. The additional concerns of providing sedation and/or general anesthesia to patients with COPD in settings outside of a hospital demand thorough investigation of individual patient presentation and realistic development of planned treatment that patients suffering from this respiratory condition can tolerate. Along with other co-morbidities, such as advanced age and potential significant cardiovascular compromise, the dental practitioner providing sedation or general anesthesia must tailor any treatment plan to address multiple organ systems and mitigate risks of precipitating acute respiratory failure from inadequate pain and/or anxiety control. Part I of this article covered the epidemiology, etiology, and pathophysiology of COPD. Patient considerations in the preoperative period were also reviewed. Part II will cover which patients are acceptable for sedation/general anesthesia in the dental office-based setting as well as sedation/general anesthesia techniques that may be considered. Postoperative care will also be reviewed.

    摘要：Dental treatment of young pediatric patients can be confounded by lack of cooperation for dental rehabilitation procedures and even examination and/or radiographs. With the recent US Food and Drug Administration warning applied to many anesthetic/sedative agents for children less than 3 years old, a retrospective review of general anesthesia (GA) cases from 1 private pediatric dental practice was studied for age, gender, body mass index, anesthetic duration, airway management used, extent of dental surgical treatment, recovery time, and cardiac/pulmonary complications. For the 2016 calendar year, 351 consecutive GA cases were identified with patients aged 2–13 years. Of these, 336 underwent nasal endotracheal intubation. Forty-six of 351 patients (13%) were younger than 3 years. Median anesthesia duration was approximately 1.7 hours for all age groups. Dental treatment consisting of 8–9 teeth including crowns, fillings, and extractions was most frequently encountered. One hundred sixty-eight patients (48%), however, required care for 10–18 teeth. There were no episodes of significant oxygen desaturation. The overall complication rate was 1.1%, with 2 cases of postextubation croup, 1 case of mild intraoperative bronchospasm, and 1 case of intraoperative bradycardia. Complications did not correlate with children being overweight or obese.

    机译 使用计算机控制的局麻药（CCLAD）进行下牙槽神经阻滞注射疼痛：一项前瞻性随机研究
    摘要：There is evidence that the Computer-Controlled Local Anesthetic Device (CCLAD) decreases the pain of oral injections. The purpose of this study was to evaluate injection pain of the inferior alveolar nerve block (IANB) using the CCLAD in an upright position versus a supine position. Additionally, we evaluated solution deposition pain with the CCLAD when compared to previous studies using a traditional syringe. One hundred ten asymptomatic subjects were randomly given IANBs using 2% lidocaine with 1:100,000 epinephrine while in an upright sitting position and supine position, at 2 different appointments, spaced at least 2 weeks apart. Each subject rated the pain for needle insertion, needle placement, and solution deposition on a Heft-Parker visual analogue scale. Pain ratings were compared between the upright and supine positions using a repeated-measures analysis of variance with post hoc testing using the Tukey-Kramer procedure. Moderate to severe pain was reported by 10% to 13% of the patients for needle insertion, 74% to 75% for full needle placement, and 8% to 10% for solution deposition. There was no significant difference between groups for phases of the injection. When comparing the injection phases within the groups, the needle placement phase of the injection was statistically more painful than both the needle insertion phase and solution deposition phase (p = .0001). Using the CCLAD, IANB injection pain of the supine and upright positions was not statistically different. Needle placement was the most painful phase of the injection. Solution deposition pain was less with the CCLAD when compared to other studies of the IANB using a traditional syringe.

    【2hr】The Effects of Mouth Opening and Throat Pack Placement on Uncuffed Nasal Endotracheal Tube Leakage and Delivered Tidal Volumes in Mechanically Ventilated Pediatric Patients Undergoing Dental Procedures

    摘要：Intubation for pediatric patients is frequently performed with an uncuffed endotracheal tube (ETT), which may result in an incomplete tracheal seal, resulting in gas leakage (leak). The purpose of this study was to assess the effect of (1) mouth opening and (2) throat pack placement in sealing and/or minimizing this leak to an acceptable level while providing adequate tidal volumes in mechanically ventilated patients. This prospective study of 2- to 6-year-olds undergoing general anesthesia with nasal intubation for dental procedures in the New York University–Lutheran Medical Center operating room was conducted between March 2015 and October 2015. Three sequential tidal volume (VT) measurements were recorded: postintubation with the neck extended, with mouth opened, and after throat pack placement. Twenty-five subjects were included in the analyses. For subjects in whom no leak was detected, only throat pack placement statistically improved VT. This is in marked contrast to numerically large, statistically significant effects, relative to baseline, for mouth opening (±23.2 mL, p < .009, 21% increase from baseline) and throat pack placement (±46 mL, p < .009, 41% increase from baseline) when a leak was detected. In children 2–6 years of age, nasal intubation with uncuffed ETTs that have incomplete tracheal seal have improved VT with mouth opening and throat pack placement. This finding suggests that the intubation procedure is a process that extends through positioning, mouth opening, and throat pack placement.

    【2hr】A Histological Study of Vasoconstriction by Local Anesthetics in Mandible

    机译 下颌骨局麻药对血管收缩的组织学研究
    摘要：To assess the effect of epinephrine-containing local anesthetics on vasoconstriction, we immunohistochemically measured the intravascular lumen area in different regions of the mandible. Twelve male Wistar rats were used. General anesthesia was induced and maintained with sevoflurane. Infiltration anesthesia was performed with 0.2 mL of epinephrine-free 2% lidocaine (E−) near the left mandibular first molar and with 0.2 mL of epinephrine-containing 2% lidocaine (E+) near the right mandibular first molar. After decalcification, the specimens were paraffinized, and thin sections were prepared and immunohistologically stained with an antismooth muscle actin antibody. The intravascular lumen area was measured in the mucosa, periodontal membrane, Haversian/Volkmann's canal, and bone marrow. A Mann-Whitney U test was used for statistical processing, and p < .05 was considered to indicate a statistically significant difference. In the oral mucosa and the periodontal membrane, E+ had a significantly smaller vascular lumen area than E−. In the Haversian/Volkmann's canal and the bone marrow, no significant intergroup difference was observed in the intravascular lumen area. We postulate that this is due to a low smooth muscle content of blood vessels in the mandible and suggest that the vasoconstrictive effect of epinephrine-containing local anesthetics within the mandible is ineffective.

    【2hr】Difficult Nasal Intubation Using Airway Scope® for a Child With Large Tumor

    包量

    机译 使用AirwayScope®对患有大肿瘤的儿童进行困难的鼻插管
    摘要：We report a case of difficult nasal intubation utilizing a Pentax-Airway scope® AWS-100. A 4-month-old female with a rapidly growing melanotic neuroectodermal tumor was scheduled for resection under general anesthesia. The tumor was a large rubbery mass located in the middle of the mandible. For nasal intubation using the AWS, guidance of the tube toward the glottis was attempted using pediatric Magill forceps. Although we could hold the tube with the Magill forceps, it was difficult to insert the tube into the trachea due to the limited space in her hypopharynx. We then used a standard laryngoscope with a Miller straight blade for direct visual laryngoscopy and successfully intubated the patient with the aid of the pediatric Magill forceps. We often experience difficulty navigating a nasal endotracheal tube toward the glottis even when a clear glottic view is obtained with video laryngoscopes, especially in children with a small oropharyngeal space. However, some reports have been shown that video laryngoscopes are useful for intubation of the difficult airway and causes less stress to the upper airway than direct visual laryngoscopy. Video laryngoscopy can be an excellent way to provide nasal intubation in some but not all children.
