To emphasize the utility of office-based transnasal esophagoscopy (TNE) in the evaluation of patients with swallowing complaints, we present 2 case reports and a review of the literature. The 2 patients both presented with complaints of chronic dysphagia, globus sensation, and a sensation of “food sticking” with swallowing. The patients were counseled to undergo esophagoscopy. Informed consent was obtained. The nasal cavities and pharynx were anesthetized with topical 4% lidocaine hydrochloride solution. Transnasal esophagoscopy was performed. The procedure was well tolerated by the patients. Esophagoscopy revealed diverticuli in various segments of the esophagus, including the midesophageal and distal areas. The cause of the patients' complaints could be well attributed to the endoscopic findings. No morbidity was associated with the TNE examination. A review of the literature concerning office-based TNE was performed. We found no published reports of middle or distal esophageal diverticuli detected on routine office TNE. We conclude that transnasal esophagoscopy is a relatively safe and efficient tool that can be used in the office setting for evaluation of swallowing complaints.

The purpose of this study was to examine how submucosal injection of a clinically relevant dose of a lidocaine hydrochloride solution containing epinephrine affects the muscle relaxant effects of rocuronium bromide. Sixteen patients scheduled for orthognathic surgery participated in this study. All patients were induced with fentanyl citrate, a target-controlled infusion of propofol and rocuronium bromide. Anesthesia was maintained by total intravenous anesthesia. After nasotracheal intubation, an infusion of rocuronium bromide was started at 7 µg/kg/min, and the infusion rate was then adjusted to maintain a train of four (TOF) ratio at 10 to 15%. The TOF ratio just prior to oral mucosal injection of a 1% lidocaine hydrochloride solution containing 10 µg/mL epinephrine (LE) was taken as the baseline. TOF ratio was observed for 20 minutes, with 1-minute intervals following the start of injection. Mean epinephrine dose was 85.6 ± 18.6 µg and mean infusion rate of rocuronium bromide was 6.3 ± 1.6 µg/kg/min. TOF ratio began to decrease 2 minutes after the injection of LE, reached the minimum value at 3.1 ± 3.6% 12 minutes after the injection, and then began to recover. We conclude that oral mucosal injection of LE enhances the muscle relaxant effects of rocuronium bromide.

Prolonged Drug Release

Lipid particles, as drug carriers, are of increasing research interest, because a sustained drug release and avoidance of side effects could be achieved by using them. Lidocaine hydrochloride is a very efficient local anesthetic, but it has a short effect. The objective was to prolong the effect of the drug by encapsulating lidocaine hydrochloride in phospholipids microparticles. Two different procedures were used for the preparation of phospholipids microparticles. In both cases, phosphatidylcholine and lysophosphatidylcholine were used for the preparation of microparticles in which 5 % w/w lidocaine hydrochloride solution was encapsulated. The standard Franz diffusion cell was used for the experimental diffusion rate determination. The obtained results show that diffusion rate from microparticles is significantly lower than from the lidocaine hydrochloride solution, which means that this kind of microparticles could be used for the prolonged drug release. There was no much difference in diffusion rates from microparticles obtained by different procedures. That indicates that only the composition of the particles membrane has an influence on the lidocaine hydrochloride release rate.
