Comparative StudyPost-sedation events in children sedated for dental care.
Moderate oral sedation is used in pediatric dentistry for safe delivery of dental care to children. However, there is a paucity of data on the effects of pediatric dental sedations after discharge of children from the dental office. The purpose of this study was to evaluate and compare the incidence of adverse events occurring with meperidine and hydroxyzine versus midazolam alone 8 and 24 hours after sedation in pediatric dental patients. ⋯ There were no statistical differences between the 2 groups with respect to incidence of pain, fever, vomiting, sleeping in the car, snoring, and difficulty in waking up. The lingering effects of orally administered sedation medications can lead to prolonged sleep, irritability, and vomiting in children after they have been discharged from the dental clinic. Most of these events occurred within the first 8 hours, but in some children the effects were seen up to 24 hours later.

Comparative StudyVentilation via cut nasotracheal tube during general anesthesia.
Many patients with disabilities need recurrent dental treatment under general anesthesia because of high caries prevalence and the nature of dental treatment. We evaluated the use of a nasal device as a possible substitute for flexible laryngeal mask airway to reduce the risk of unexpected failure accompanying intubation; we succeeded in ventilating the lungs with a cut nasotracheal tube (CNT) with its tip placed in the pharynx. We hypothesized that this technique would be useful during dental treatment under general anesthesia and investigated its usefulness as part of a minimally invasive technique. ⋯ Mouth gags slightly reduced the rate of effective ventilation in the neck flexion position. Most dental treatments involving minor oral surgeries were performed using mouth gags during CNT ventilation. CNT ventilation was shown to be superior to mask ventilation and is useful during dental treatment under general anesthesia.

ReviewPrevention of sevoflurane delirium and agitation with propofol.
Emergence delirium and agitation (EAD) associated with sevoflurane general anesthesia are very commonly observed in young children. Such events pose a risk for injury as well as decreased parental satisfaction, especially in the ambulatory and office-based setting. This article reviews the different approaches described in the literature to reduce EAD. A novel approach using a Bispectral Index System (BIS)-guided anesthesia with propofol washout technique is proposed as a viable and effective approach to prevent EAD.

Randomized Controlled TrialAnesthetic efficacy of a combination of 0.9 M mannitol plus 68.8 mg of lidocaine with 50 μg epinephrine in inferior alveolar nerve blocks: a prospective randomized, single blind study.
The purpose of this prospective randomized, single blind study was to determine the anesthetic efficacy of 68.8 mg of lidocaine with 50 μg epinephrine compared to 68.8 mg lidocaine with 50 μg epinephrine plus 0.9 M mannitol in inferior alveolar nerve (IAN) blocks. Forty subjects randomly received 2 IAN blocks consisting of a 1.72-mL formulation of 68.8 mg lidocaine with 50 μg epinephrine and a 5-mL formulation of 68.8 mg lidocaine with 50 μg epinephrine (1.72 mL) plus 0.9 M mannitol (3.28 mL) in 2 separate appointments spaced at least 1 week apart. Mandibular anterior and posterior teeth were blindly electric pulp tested at 4-minute cycles for 60 minutes postinjection. ⋯ The results demonstrated that the 5 mL-formulation of 68.8 mg lidocaine with 50 μg epinephrine plus 0.9 M mannitol was significantly better than the 1.72-mL formulation of 68.8 mg lidocaine with 50 μg epinephrine for all teeth, except the lateral incisor. We concluded that adding 0.9 M mannitol to a lidocaine with epinephrine formulation was significantly more effective in achieving a greater percentage of total pulpal anesthesia (as defined in this study) than a lidocaine formulation without mannitol. However, the 0.9 M mannitol/lidocaine formulation would not provide 100% pulpal anesthesia for all the mandibular teeth.

Randomized Controlled Trial Comparative StudyA comparison of fospropofol to midazolam for moderate sedation during outpatient dental procedures.
Moderate intravenous (IV) sedation combined with local anesthesia is common for outpatient oral surgery procedures. An ideal sedative agent must be safe and well tolerated by patients and practitioners. This study evaluated fospropofol, a relatively new sedative/hypnotic, in comparison to midazolam, a commonly used benzodiazepine, for IV moderate sedation during oral and maxillofacial surgery. ⋯ Two adverse effects demonstrated significance, with more patients in the midazolam group experiencing tachycardia (48.2 vs 9.4%, P = .001), and more patients in the fospropofol group experiencing perineal discomfort (40.6 vs 0, P < .001). No significant difference was found in any other measures of sedation safety, maintenance, or satisfaction. Fospropofol, when administered intravenously by a dentist anesthesiologist at the indicated dose in this study, appears to be a safe, well-tolerated alternative to midazolam for intravenous moderate sedation during minor oral surgery procedures.
