Randomized Controlled TrialAnesthetic efficacy of combinations of 0.5 m mannitol and lidocaine with 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 lidocaine with epinephrine compared to lidocaine with epinephrine plus 0.5 M mannitol in inferior alveolar nerve (IAN) blocks. Forty subjects randomly received an IAN block in 3 separate appointments spaced at least 1 week apart using the following formulations: a 1.8 mL solution of 36 mg lidocaine with 18 µg epinephrine (control solution); a 2.84 mL solution of 36 mg lidocaine with 18 µg epinephrine (1.80 mL) plus 0.5 M mannitol (1.04 mL); and a 5 mL solution of 63.6 mg lidocaine with 32 µg epinephrine (3.18 mL) plus 0.5 M mannitol (1.82 mL). Mandibular teeth were blindly electric pulp tested at 4-minute cycles for 60 minutes postinjection. ⋯ The 5 mL of lidocaine with epinephrine plus 0.5 M mannitol was statistically better than 1.8 mL of lidocaine with epinephrine and 2.84 mL of lidocaine with epinephrine plus 0.5 M mannitol for all teeth except the central incisor. Solution deposition pain and postoperative pain were not statistically different among the mannitol formulations and the lidocaine formulation without mannitol. We concluded that adding 0.5 M mannitol to lidocaine with epinephrine formulations significantly improved effectiveness in achieving a greater percentage of total pulpal anesthesia compared with a lidocaine formulation without mannitol for IAN block.

Randomized Controlled TrialEfficacy of anesthetic agents to delay pain onset after periodontal surgery.
The aim of this study was to evaluate the influence of 2 anesthetic agents on patients' postoperative pain perception after periodontal surgery. For this parallel-group, double-blinded, randomized clinical trial, 36 open flap debridement surgeries were performed on patients who presented with periodontal disease with clinical signs of inflammation after nonsurgical treatment on at least 1 quadrant. Patients were allocated to 1 of the following groups: group 1, 2% lidocaine with 1 ∶ 100,000 epinephrine; group 2, 2% mepivacaine with 1 ∶ 100,000 norepinephrine. ⋯ All patients received 750-mg acetaminophen tablets, which they were instructed to take as a rescue medication if necessary. The results demonstrated that postoperative pain intensity was statistically lower in group 2 than in group 1 at the 1-, 2-, and 3-hour periods after surgery, although the pain intensity for all groups could be considered mild. In conclusion, patients in both groups reported similar mild pain after periodontal surgery.

Recognition and management of complications during moderate and deep sedation. Part 2: cardiovascular considerations.
The risk for cardiovascular complications while providing any level of sedation or general anesthesia is greatest when caring for patients already medically compromised. It is reassuring that significant untoward events can generally be prevented by careful preoperative assessment, along with attentive intraoperative monitoring and support. Nevertheless, providers must be prepared to manage untoward events should they arise. This continuing education article will review cardiovascular complications and address their appropriate management.

Recognition and management of complications during moderate and deep sedation part 1: respiratory considerations.
The risk for complications while providing any level of sedation or general anesthesia is greatest when caring for patients having significant medical compromise. It is reassuring that significant untoward events can generally be prevented by careful preoperative assessment, along with attentive intraoperative monitoring and support. Nevertheless, we must be prepared to manage untoward events should they arise. This continuing education article will review respiratory considerations and will be followed by a subsequent article addressing cardiovascular considerations.

Comparative StudyContribution of dentist anesthesiologists to dental anesthesiology research.
In order to determine if dentist anesthesiologists (DAs) actively contribute to research in the field of anesthesiology, and thus contribute new knowledge to the field, an extensive literature search was accomplished. DAs make up only 1.5% of dentists who actively contribute to anesthesia research but account for 10% of publications. ⋯ The results show that the impact of top DA researchers in dental anesthesiology is similar to the impact of top dental specialty researchers, despite lack of academic departments in dental schools where a large percentage of dental research is completed. Dentist anesthesiologists actively contribute to the research in anesthesiology for dentistry and thus, actively contribute to new knowledge in the field.
