Abstract

The aim of the study was to demonstrate if 2% lidocaine hydrochloride with 1 : 200,000 epinephrine could provide palatal anesthesia in maxillary tooth removal with a single buccal injection. The subjects included in the clinical study were those requiring extraction of the maxillary third molar of either side. For the purpose of comparison, the sample was randomly divided into 2 main groups: group 1 (study group) included 100 subjects who were to receive a single injection before extraction, and group 2 (control group) included 100 subjects who were to receive a single buccal injection and a single palatal injection before extraction. After 5 minutes the extraction was performed. All patients were observed for Faces Pain Scale during extraction and asked for the same on a 100-mm visual analog scale after extraction. According to visual analog scale and Faces Pain Scale scores, when maxillary third molar removal without palatal injection (study group) and with palatal injection (control group) were compared the difference was not statistically significant (P > .05). Removal of maxillary third molars without palatal injection is possible by depositing 2 mL of 2% lidocaine hydrochloride with 1 : 200,000 epinephrine to the buccal vestibule of the tooth.

Abstract

The purpose of this study was to measure and compare peak methemoglobin levels and times to peak methemoglobin levels following the use of prilocaine and lidocaine in precooperative children undergoing comprehensive dental rehabilitation under general anesthesia. Ninety children, 3–6 years of age, undergoing dental rehabilitation under general anesthesia were enrolled and randomly assigned into 3 equal groups: group 1, 4% prilocaine plain, 5 mg/kg; group 2, 2% lidocaine with 1 : 100,000 epinephrine, 2.5 mg/kg; and group 3, no local anesthetic. Subjects in groups 1 and 2 were administered local anesthetic prior to restorative dental treatment. Methemoglobin levels (SpMET) were measured and recorded throughout the procedure using a Masimo Radical-7 Pulse Co-Oximeter (Masimo Corporation, Irvine, Calif, RDS-1 with SET software with methemoglobin interface). Data were analyzed using chi-square, one-way analysis of variance (ANOVA), and Pearson correlation (significance of P < .05). Group 1 had a significantly higher mean peak SpMET level at 3.55% than groups 2 and 3 at 1.63 and 1.60%, respectively. The mean time to peak SpMET was significantly shorter for group 3 at 29.50 minutes than that of group 1 at 62.73 and group 2 at 57.50 minutes. Prilocaine, at 5 mg/kg in pediatric dental patients, resulted in significantly higher peak SpMET levels than lidocaine and no local anesthetic. In comparison to no local anesthetic, the administration of prilocaine and lidocaine caused peak SpMET levels to occur significantly later in the procedure.

Abstract

The Parker Flex-Tip tracheal tube (PFTT, Parker Medical, Highlands Ranch, Colo) has a soft, flexible, curved tip with double Murphy eyes. Previous studies have shown that the PFTT reduces the incidence of epistaxis during nasotracheal intubation and the incidence of postintubation nasal pain, as compared to conventional tracheal tubes. Although thermosoftening is a well-known and effective technique for reducing epistaxis during nasotracheal intubation with conventional tracheal tubes, we occasionally encounter difficulties with advancing the tube through the nasal passage when the PFTT is thermosoftened prior to nasotracheal intubation. Consequently, when using the PFTT for nasotracheal intubation, the procedure of thermosoftening should be avoided.

Uncuffed Tracheal Tube Size in Pediatric Patients Aged below 2 Years

J Jpn Dent Soc Anesthesiol 2012;40:587–591.

Cole's formula (tube size = 0.25 × age + 4) is usually used to calculate uncuffed endotracheal tube (ETT) size in pediatric patients aged above 2 years, but is not applicable for younger patients. The purpose of this study was to investigate the relationship between ETT
