Background Topical anesthetics, such as eutectic mixture of local anesthetics (EMLA) cream, can be applied to reduce pain before minor procedure. This trial evaluated EMLA as pretreatment for facial lacerations and compared pain, discomfort and overall satisfaction. Methods This trial included consecutive emergency department patients ${\geq}16years$ of age who presented with simple facial lacerations. At triage, lacerations were allotted to either the routine processing group or EMLA pretreatment group according to date of admission. Initially, the emergency department doctors inspected each laceration, which were dressed with saline-soaked gauze. In the pretreatment group, EMLA cream was applied during wound inspection. The plastic surgeon then completed primary closure following the local injection of an anesthetic. After the procedure, all patients were given a questionnaire assessing pain using the 10-point visual analog scale (VAS) ("no pain" to "worst pain"). All questionnaires were collected by the emergency department nurse before discharge. Results Fifty patients were included in the routine processing group, and fifty patients were included in the EMLA pretreatment group. Median age was 39.9 years, 66% were male, and the average laceration was 2.67 cm in length. The EMLA pretreatment group reported lower pain scores in comparison with the routine processing group (2.4 vs. 4.5 on VAS, P<0.05), and lower discomfort scores during the procedure (2.0 vs. 3.3, P=0.60). Overall satisfaction was significantly higher in the EMLA pretreatment group (7.8 vs. 6.1, P<0.05). Conclusions Pretreating facial lacerations with EMLA topical cream aids patients by reducing pain and further enhancing overall satisfaction during laceration treatment.

치과치료를 위하여 마취를 시행할 때 아동들의 주사기나 주사바늘에 대한 불편감을 감소시키기 위한 여러 방법들이 있다. 도포마취제의 사용이 한 가지 방법이다. 도포마취는 많은 임상과정, 즉 주사침 자입부위, 간단한 유치발치, 구토반응이 심한 환자에서 치과용 구내 방사선 촬영시, 인상채득 전 구토반응의 감소 목적 등으로 사용되어 왔다. 또한 소아에서 치면열구전색술과 예방심미수복술시 치아격리를 위한 러버댐 clamp의 장착은 불편감을 유발할 수 있는데, 도포마취는 이런 목적으로 러버댐 장착시 도움이 된다. 모든 구강내 도포마취제는 점막에 동등한 효과가 있다고 제안되었으나, 1980년대 개발되어 피부의 표면마취에 사용되는 EMLA(acronym for eutectic mixture of local anaesthetics)가 기존의 도포마취제보다 부착치은에 사용시 더 효과가 있다고 보고되고 있다. 본 증례에서는 침윤마취가 필요한 몇 증례에서 EMLA cream을 이용하여 국소마취를 하기 전단계, 유치 발거시, clamp 장착시, 기성관 수복 등에서 동통을 감소시킴으로써 환아의 치과 치료에 대한 불안감을 감소시키는데 매우 효과적이었기에 보고하는 바이다.

Chloral hydrate와 hydroxizine을 이용한 경구진정법은 적용대상의 나이와 체중에 따라 제한을 받는다. 일반적으로 경구 진정법은 36개월 미만, 체중 15 kg 미만의 환아에서 가장 좋은 진정 효과를 보인다. 그러나 36개월 이상 또는 15 kg 이상의 환아에 대해서는 경구진정법이 적절한 진정 효과를 얻는데 한계를 가지며, 얕은진정으로 인해 시술 중 잦은 움직임을 보여 쉽게 진정에 실패하게 된다. 진정 실패 시 고려 할 수 있는 대안은 추가적인 약제 투여로 인한 재진정의 유도나, 좀 더 깊은진정 법으로의 전환이 있다. 그러나 깊은진정법으로의 전환은 환아의 움직임과 동통의 감소를 위해 흡입마취제 및 마취기계가 요구되어 외래 진료실에서는 쉽게 선택되지 못한다. EMLA cream(Eutectic Mixture of Local Anesthesia)은 피부의 도포마취를 위해 널리 사용되고 있는 약제로 본 증례에서는 이를 이용하여 자극 없이 정주진정 경로를 확보하여 경구진정에서 정주진정으로의 전환에 성공하였다. 만 46개월, 체중 15 kg 남아가 다발성 우식을 주소로 단국대학교 치과대학 병원 소아치과에 내원하였다. 일반적인 행동조절 하에 치료 권유하였으나 보호자의 요구에 의해 경구진정 시도하였으며, 경구진정 실패를 고려하여 복용 전 EMLA cream을 사전 도포하였다. 경구 복용 90분 경과 뒤에도 진정효과를 얻지 못하여 보호자의 동의하에 아산화질소를 이용하여 얕은진정 유도 후, EMLA cream 도포 부위에 정맥로를 확보하였다. 총 시술 시간 2시간 30분으로 특별한 부작용 없이 성공적으로 시술을 완료하였다.

Purpose: Newborns routinely experience pain associated with invasive procedures such as blood sampling, venipuncture, heelstick, or venous cannulation. This study was done to provide data for a nursing intervention to alleviate newborn pain clinically by investigating the effect of local anesthetic cream during venipuncture. Methods: Participants were 70 newborns hospitalized in the nursery. Informed Consent was obtained from parents of the newborns. Venipuncture for regular blood sampling was carried out for a test on 2 groups; the experimental, placebo group. The neonatal infant pain scale (NIPS), and duration of crying were measured to assess pain reaction. All neonatal behaviors were recorded on videotape. Results: There were significant differences in pain behavior during venipuncture (t=-4.752, p<.001), immediately after sampling (t=-5.591, p<.001), 3 minutes after puncture (t=-2.469, p=.017), and in duration of crying (t=-3.005, p=.004). Conclusion: Results show that local administration of EMLA cream before venipuncture causes a reduction in neonatal pain response, indicating that the EMLA cream has the effect of pain relief.

Background: This study evaluated the efficacy of three intraoral topical anesthetics in reducing the injection needle prick pain from local anesthetic among children aged 7-11 years old. Methods: It is a prospective, Interventional, parallel design, single-blind, randomized clinical trial in which subjects (n=90) aged 7-11 years were included in the study based on an inclusion criteria. Subjects were divided into three groups based on computer-generated randomization with an allocation ratio of 1:1:1. Groups A, B, and C received benzocaine 20% jelly (Mucopain gel, ICPA health products Ltd, Ankleshwar, India), cetacaine anesthetic liquid (Cetylite Industries, Inc, Pennsauken, NJ), and EMLA cream (2% AstraZeneca UK Ltd, Luton, UK), respectively, according to manufacturer's instructions, for 1 minute prior to local anesthetic injection. After application of topical anesthetic agent, for all the groups, baseline pre-operative (prior to topical anesthetic administration) and post-operative scores (after local anesthetic administration) of pulse rate was recorded using Pulse oximeter (Gibson, Fingertip Pulse Oximeter, MD300C29, Beijing Choice Electronic). Peri-operative (i.e., during the administration of local anesthesia) scores were recorded using Face, Legs, Activity, Cry, Consolability (FLACC) Scale, Modified Children hospital of Eastern Ontario Pain Scale (CPS) behavior rating scale, and Faces Pain Scale (FPS-R) - Revised (For self-reported pain). Direct self-reported and physiological measures were ascertained using FPS-R - Revised and Pulse oximeter, respectively, whereas CPS and FLACC scales assessed behavioral measures. To test the mean difference between the three groups, a one way ANOVA with post hoc tests was used. For statistical significance, a two-tailed probability value of P < 0.05 was considered as significant. Results: The Cetacaine group had significantly lower pain scores for self-report (P < 0.001), behavioral, and physiological measures (P < 0.001) than the other two groups. However, there was no significant difference between the Benzocaine group and EMLA group during palatal injection prick. Conclusion: Cetacaine can be considered as an effective topical anesthetic agent compared to benzocaine 20% jelly (Mucopain gel) and EMLA cream.

Topical anesthetics act on the peripheral nerves and reduce the sensation of pain at the site of application. In dentistry, they are used to control local pain caused by needling, placement of orthodontic bands, the vomiting reflex, oral mucositis, and rubber-dam clamp placement. Traditional topical anesthetics contain lidocaine or benzocaine as active ingredients and are used in the form of solutions, creams, gels, and sprays. Eutectic mixtures of local anesthesia cream, a mixture of various topical anesthetics, has been reported to be more potent than other anesthetics. Recently, new products with modified ingredients and application methods have been introduced into the market. These products may be used for mild pain during periodontal treatment, such as scaling. Dentists should be aware that topical anesthetics, although rare, might induce allergic reactions or side effects as a result of an overdose. Topical anesthetics are useful aids during dental treatment, as they reduce dental phobia, especially in children, by mitigating discomfort and pain.

Purpose: A eutectic mixture of local anesthetics (EMLA$^{(R)}$) cream has been used as a topical anesthetic to reduce the pain of procedures penetrating the skin. It is generally applied for 40 to 60 minutes before the painful procedure. Because of the long application period, EMLA$^{(R)}$ is not useful in the emergency department (ED). The purpose of this study was to determine whether a 20-minute application of 9.6% lidocaine would be useful in reducing the pain of routine peripheral intravenous cannulation in the ED. Methods: We examined 27 male and 19 female patients ages over 18 years of age who required intravenous cannula insertion. Intravenous insertion was performed on 46 patients: 24 patients in the placebo group (mean age: 40.0 years) and 22 in the 9.6% lidocaine group (mean age: 37.6 years). The 9.6% lidocaine or placebo gel was applied and covered with an occlusive dressing for 20 minutes. Pain was scored by the patients using a 0- to 10-cm visual analogue scale. Results: The patients in the 9.6% lidocaine group (mean pain score: 3.4) experienced less pain than those in the placebo group (mean: 5.3), and the difference was statistically significant (p=0.029). Conclusion: We concluded that a 20-minute application of 9.6% lidocaine is safe and effective for reducing pain associated with venipuncture.
