1.  A Survey of Pain, Pressure, and Discomfort Induced by Commonly Used Oral Local Anesthesia Injections 
Anesthesia Progress  2005;52(4):122-127.
Intraoral local anesthesia is essential for delivering dental care. However, it is often perceived by some patients as the most painful and in some instances as the only painful part of the treatment, leading in extreme cases to avoidance of dental care. The present study measured the variables of pain, pressure, and discomfort caused by 4 commonly used local anesthesia injections: local infiltration, mental nerve block, inferior alveolar nerve block, and periodontal ligament injections. Patients were asked to grade pain, discomfort, and pressure on a visual analog scale as associated with needle insertion, operator finger position in the mouth, and pressure at injection. The inferior alveolar injection was graded to be the most painful followed by periodontal ligament and then mental nerve block injections. The periodontal ligament injections yielded the highest pressure scores. The inferior alveolar block injection yielded significantly more discomfort than local infiltration and mental nerve block injections when comparing finger and needle position. Local infiltration in the anterior maxillary region yielded the highest needle insertion and finger position discomfort scores. The present study suggests that the dental operator should be aware of local anesthesia injection pain, pressure, and discomfort together with efficacy of technique.

2.  Drug Therapy in Dental Practice: Nonopioid and Opioid Analgesics 
Anesthesia Progress  2005;52(4):140-149.
To prevent patient pain, the clinician may chose from opioid and nonopioid analgesics. It is rational for the practitioner to combine drugs from these classes when managing moderate to severe pain. To select combination regimens wisely, it is necessary to understand the significant pharmacological features of each category alone. Careful selection of an effective analgesic regimen based on the type and amount of pain the patient is expected to have can prevent the stress and anxiety associated with breakthrough pain. The clinician can and should develop a variety of effective, safe analgesic regimens, based on estimates of anticipated pain intensity that use sound pharmacological principles.

3.  Anesthetic Efficacy of Bupivacaine Solutions in Inferior Alveolar Nerve Block 
Anesthesia Progress  2005;52(4):132-135.
The purpose of this study was to compare the anesthetic efficacy of 2 bupivacaine solutions. Twenty-two volunteers randomly received in a crossover, double-blinded manner 2 inferior alveolar nerve blocks with 1.8 mL of racemic bupivacaine and a mixture of 75% levobupivacaine and 25% dextrobupivacaine, both 0.5% and with 1 : 200,000 epinephrine. Before and after the injection, the first mandibular pre-molar was evaluated every 2 minutes until no response to the maximal output (80 reading) of the pulp tester and then again every 20 minutes. Data were analyzed using the Wilcoxon paired test and the paired t test. No differences were found between the solutions for onset and duration of pulpal anesthesia and duration of soft tissue anesthesia (P > .05). It was concluded that the solutions have similar anesthetic efficacy.

4.  Zaleplon (Sonata) Oral Sedation for Outpatient Third Molar Extraction Surgery 
Anesthesia Progress  2005;52(4):128-131.
Zalpelon was compared with triazolam for oral sedation in a third molar surgery model using a double-blind crossover design. Factors such as anxiolysis, amnesia, and quality of sedation were assessed. Of the 14 participants who completed the study, zaleplon sedation was found to be similar to triazolam sedation in all regards except that recovery from zaleplon was more rapid.

7.  Benzocaine-induced Methemoglobinemia 
Anesthesia Progress  2005;52(4):136-139.
A case is reported in which a patient developed methemoglobinemia-induced cyanosis while under general anesthesia during surgery for multiple fascial space infections. The cause of methemoglobinemia was 20% benzocaine spray used for local anesthesia before intubation. Acutely developing methemoglobinemia is infrequently encountered in clinical practice. When confronted with cyanosis in the absence of cardiac or pulmonary disease, one must seriously consider the diagnosis of methe-moglobinemia. The etiology of methemoglobinemia, the causative agents, the diagnosis, and the emergency treatment required are discussed.

11.  Outpatient Anesthesia for Oral Surgery in a Juvenile With Leigh Disease 
Anesthesia Progress  2005;52(2):70-73.
We report a case of anesthesia for elective outpatient third molar extraction in a juvenile with Leigh disease, a progressive neurodegenerative disorder related to respiratory chain deficiency. This syndrome usually presents in infancy and is characterized by nervous system dysfunction and respiratory abnormalities. Anesthesia has been reported to aggravate respiratory symptoms and frequently precipitate respiratory failure. Preoperative swallowing difficulty or respiratory symptoms should be carefully diagnosed, because they can be a warning sign of postoperative complications or mortality. Adverse effects of anesthesia may quickly lead into metabolic acidosis. Anesthetics should be carefully chosen that do not interfere with mitochondrial respiration, which can lead to lactic acidosis.

12.  A Case of a Power Failure in the Operating Room 
Anesthesia Progress  2005;52(2):65-69.
In the operating room, safely administering anesthesia amidst a major power failure can instantly present one with a formidable challenge. A case is presented involving a 23-year-old healthy woman who underwent a complex oral and maxillofacial surgery to correct a dentofacial deformity. Three hours into the case and with the patient's maxilla downfractured, the overhead surgical lights blacked out, and there was an apparent loss of the anesthesia machine's ability to function. Providing adequate oxygenation, ventilation, anesthesia levels, monitoring of vital signs, and transportation of the patient were some of the challenges faced, and the response to this unexpected event is recounted. The importance of one's familiarity with an anesthesia machine's backup battery supply, routinely checking machinery, ensuring that appropriate and sufficient supplies are readily available, exercising calm leadership with clear communication, and formulating a clear plan with backup alternatives are discussed. Various recommendations are proposed with respect to the preparation for and the prevention of a power failure in the operating room. This report's account of events is aimed to “shed some light” on this topic, serve as a check of one's own preparedness, and facilitate the optimal management of a similarly unexpected incident.

13.  Lack of Pain Reduction by a Vibrating Local Anesthetic Attachment: A Pilot Study 
Anesthesia Progress  2005;52(2):62-64.
A vibrating dental local anesthesia attachment (Vibraject, LLC, Calif) based on the concept of the gate-control theory has been used in clinical practice. The theoretical advantage of the vibrating needle is that it reduces the injection pain. We evaluated the effectiveness of Vibraject in combination with an electrical injection device. Injections were given into the alveolar mucosa adjacent to the root apex of the maxillary lateral incisor in 10 volunteers. Vibraject was randomly applied to either the left or right side of the injection. No statistically significant decrease in pain scores was found at needle insertion or anesthetic injection. The clinical efficacy of Vibraject remains controversial.

14.  Midazolam Premedication in Children: A Pilot Study Comparing Intramuscular and Intranasal Administration 
Anesthesia Progress  2005;52(2):56-61.
The purpose of this study was to compare the effectiveness of intramuscular and intranasal midazolam used as a premedication before intravenous conscious sedation. Twenty-three children who were scheduled to receive dental treatment under intravenous sedation participated. The patients ranged in age from 2 to 9 years (mean age, 5.13 years) and were randomly assigned to receive a dose of 0.2 mg/kg of midazolam premedication via either intramuscular or intranasal administration. All patients received 50% nitrous oxide and 50% oxygen inhalation sedation and local anesthetic (0.2 mL of 4% prilocaine hydrochloride) before venipuncture. The sedation level, movement, and crying were evaluated at the following time points: 10 minutes after drug administration and at the times of parental separation, passive papoose board restraint, nitrous oxide nasal hood placement, local anesthetic administration, and initial venipuncture attempt. Mean ratings for the behavioral parameters of sedation level, degree of movement, and degree of crying were consistently higher but not significant in the intramuscular midazolam group at all 6 assessment points. Intramuscular midazolam was found to be statistically more effective in providing a better sedation level and less movement at the time of venipuncture than intranasal administration. Our findings indicate a tendency for intramuscular midazolam to be more effective as a premedication before intravenous sedation.

15.  Differences Between Men and Women Regarding Attitudes Toward Dental Local Anesthesia Among Junior Students at a United Kingdom Dental School 
Anesthesia Progress  2005;52(2):50-55.
The aim of this study was to assess the attitudes of junior dental students at a United Kingdom dental school regarding the administration and receipt of a local anesthetic injection. The effect of teaching on these attitudes was also evaluated. Data were collected by questionnaire. Previous experience with local anesthesia in a dental office did not affect students' attitudes toward administration and receipt of a local anesthetic injection from a classmate. Female students were more anxious about giving and receiving local anesthetic injections than male students. Didactic teaching decreased anxiety in relation to administration and receipt of a local anesthetic injection. The results showed that male and female students in a United Kingdom dental school differed in their attitudes toward local anesthesia.
