Purpose: The present study was done to examine the effect of music therapy on anxiety and pain in patients for whom a ureteral stent was inserted under local anesthesia. Method: The participants in this study were 22 patients who received a ureteral stent at the Day Surgery Center of C University Hospital during the period from May to October in 2006. The patients were divided into a control group (n=11) and an experimental group (n=11). For the experimental group, music was played according to their musical preference using headphones. The music was provided from the point when the patient took the posture for the operation and was covered with a sterilized drape to the point when the cystoscope was removed after finishing the operation. The control group was only provided with ordinary nursing services. Results: The results show that the provision of music therapy to these patients is effective in reducing the patients' salivary cortisol and Vas-anxiety score and stabilizing their systolic blood pressure. Conclusion: We conclude that music therapy can be actively used as a nursing intervention for reducing anxiety in patients who receive operations under local anesthesia.

Background: Articaine, commercially available in South Korea from 2004, is widely being used for dental treatments. In the surgical extraction of impacted mandibular third molars, one of the most common procedures in oral and maxillofacial surgery, the anesthetic efficacy of 4% articaine and 2% lidocaine, both with 1：100,000 epinephrine, was compared. Methods: A randomized double-blind clinical trial was conducted of 80 patients for bilateral surgical extraction of mandibular third molars with informed consents. One operator carried out the routine surgical procedures using local anesthetic 4% articaine or 2% lidocaine with the same concentration of vasoconstrictor. Latency, duration of anesthesia and the amount of anesthetic solution were recorded. A visual analog scale (VAS) was used to evaluate the intraoperative pain. Results: The pain VAS scores reported similar anesthetic effect with both local anesthetics. Not in the latency of anesthesia and the amount of anesthetic solution, statistically significant difference was found in the mean duration of anesthesia. Conclusions: It was concluded that 4% articaine could offer better or at least the same clinical feasibility compared to 2% lidocaine, particularly in terms of the duration of the local anesthesia for common dental treatments.

Background: The sight of dental injection can bring about severe anxiety in children. Therefore, an alternative method that is convenient, effective, and keeps the needle hidden making it child friendly is necessary. The objective of the study was to compare the efficacy of a camouflaged syringe and conventional syringe on behavior and anxiety in 6-11-year-old children during local anesthesia administration. Methods: The study was a randomized, crossover clinical study including 30 children. Children were separated into two groups. Group 1 consisted of 15 children aged 6-8 years while group 2 consisted of 15 children aged 9-11 years. This study involved two sessions wherein all the children were injected using conventional and camouflaged syringes in separate sessions. Their behavior was assessed using the Faces, Legs, Activity, Cry, Consolability (FLACC) behavior pain scale and anxiety was assessed by measuring changes in pulse rate. Patient and operator preferences were compared. Results: The results showed a lower mean change in pulse rate and FLACC scores in the camouflaged group, suggesting a positive behavior and lesser anxiety with camouflaged syringes than with conventional syringes. Conclusions: The use of camouflaged syringes for anesthesia was demonstrated to be effective in improving the behavior of children and decreasing their anxiety, and is therefore recommended as an alternative to the use of conventional syringes for local anesthesia.

Background: The pain caused by local anesthetic injection can lead to patient anxiety prior to surgery, potentially necessitating sedation or general anesthesia during the excision procedure. In this study, we aim to compare the pain relief efficacy and safety of using a digital automatic anesthetic injector for local anesthesia. Methods: Thirty-three patients undergoing excision of a benign soft tissue tumor under local anesthesia were prospectively enrolled from September 2021 to February 2022. A single-blind, randomized controlled study was conducted. Patients were divided into two groups by randomization: the experimental group with digital automatic anesthetic injector method (I-JECT group) and the control group with conventional injection method. Before surgery, the Amsterdam preoperative anxiety information scale was used to measure the patients' anxiety. After local anesthetic was administered, the Numeric Pain Rating Scale was used to measure the pain. The amount of anesthetic used was divided by the surface area of the lesion was recorded. Results: Seventeen were assigned to the conventional group and 16 to the I-JECT group. The mean Numeric Pain Rating Scale was 1.75 in the I-JECT group and 3.82 in conventional group. The injection pain was lower in the I-JECT group (p< 0.01). The mean Amsterdam preoperative anxiety information scale was 11.00 in the I-JECT group and 9.65 in conventional group. Patient's anxiety did not correlate to injection pain regardless of the method of injection (p= 0.47). The amount of local anesthetic used per 1 cm² of tumor surface area was 0.74 mL/cm² in the I-JECT group and 2.31 mL/cm² in the conventional group. The normalization amount of local anesthetic was less in the I-JECT group (p< 0.01). There was no difference in the incidence of complications. Conclusion: The use of a digital automatic anesthetic injector has shown to reduce pain and the amount of local anesthetics without complication.

Objective : This prospective study evaluated the use of continuous sedation using propofol and remifentanil when carpal tunnel release (CTR) was performed under local anesthesia. Methods : We sedated 60 patients undergoing CTR using local anesthesia with remifentanil at loading and continuous doses of $0.5\;{\mu}g\;kg^{-1}$ and $0.05\;{\mu}g\;kg^{-1}min^{-1}$, respectively, and propofol, using a target controlled infusion (TCI) pump set to a target of $2\;{\mu}g\;mL^{-1}$ (group A), or with the same drug doses except that the continuous remifentanil dose was $0.07\;{\mu}g\;kg^{-1}min^{-1}$ (group B) or $0.1\;{\mu}g\;kg^{-1}min^{-1}$ (group C). Results : In group B, the levels of pain when local anesthetics were administered (p = 0.001), intraoperative pain (p < 0.001) and anxiety (p = 0.001) were significantly lower than those of group A. Furthermore, the incidence of adverse events, including desaturation (p < 0.001) and vomiting (p = 0.043), was significantly lower in group B than in group C. Conclusion : Continuous sedation using an appropriate dose of remifentanil and propofol can be used as safe, efficacious ambulatory anesthesia in cases of CTR under local anesthesia, performed using only 2 mL of local anesthetic, with a high degree of patient satisfaction.

Day stay anesthesia should include: rapid smooth onset; rapid recovery without residual side effects; absence of adverse effects (N/V); and providing postoperative analgesia. General anesthesia with multi-modalities (inhalation, intravenous and local anesthesia) may be preferable in day stay surgery. Future studies on new drugs and techniques for day stay anesthesia need comparing the increased coat of newer treatments with the potential financial savings resulting from earlier hospital discharge, reduced supplemental drugs, and earlier return to work.

Background: This study was designed to compare the efficacy of DentalVibe against 2% lidocaine gel in reducing pain during the administration of local anesthetic injection in the adult population. Methods: This was a split-mouth open-label, randomized, controlled clinical study conducted in the Department of Oral and Maxillofacial Surgery of a dental institute. Fifty patients who were scheduled for bilateral dental extractions requiring an inferior alveolar nerve block were enrolled in the study. Site A (n = 50) was coated with 2% lidocaine gel followed by a local anesthetic injection, and DentalVibe with local anesthetic injection was used for Site B (n = 50). The primary outcome was pain, which was recorded immediately after the administration of anesthetic injection using the Visual Analogue Scale [VAS 0 - 10]. Results: The VAS pain scores ranged from 4 to 10 for site A and 0 to 6 for site B. Comparison between the two sites showed a statistically significant difference [Mann-Whitney U test value = 51.50, P < 0.001] favoring site B. Conclusion: This study showed that DentalVibe reduces pain during injection of local anesthesia compared to topical anesthetic gel.

Plastic surgery around the eyes is usually performed under local anesthesia, using a mixture of lidocaine and epinephrine. Blindness is a rare but devastating complication after the injection of local anesthesia in this region. Most cases reported to date have been caused by occlusion of the ophthalmic artery or central retinal artery. In this case report, however, we present a highly unusual case of blindness caused by corneal edema after a local anesthetic injection. A patient visited the emergency room with a laceration on the eyebrow, and local anesthesia was injected before suturing. Immediately after the injection, severe corneal edema developed, making it impossible to observe the structures in the anterior chamber in detail or check the light reflex and visual acuity of the naked eye. An antibiotic (moxifloxacin hydrochloride) and high-concentration steroid eyedrops were promptly applied. High-concentration steroids were also administered orally. On day 13 post-injury, the visual acuity of the naked eye improved to 1.0, and no recurrence of corneal lesions was observed. Although the cause of corneal edema after the local injection could not be conclusively identified, we hope that this report will help raise clinicians' awareness of this complication and appropriate treatment methods.

Spinal muscular atrophy (SMA) is an autosomal recessive, severe neuromuscular disorder in which degeneration of alpha motor neurons in the spine progressively weakens and ultimately paralyzes the proximal muscles. It occurs in one per 6,000-10,000 infants, and is a genetic disorder with the second-highest mortality rate worldwide. An 18-year-old male patient with SMA was referred for general anesthesia for difficulty in performing dental treatment due to limited mouth opening caused by temporomandibular joint (TMJ) pain. However, the patient had a high risk of general anesthesia complications, so TMJ pain during mouth opening was reduced through local anesthesia of the TMJ. Fortunately, the anesthesia was successful in reducing pain during mouth opening, enabling the patient to receive dental treatment with an adequate mouth opening.
