Purpose: The purpose of this study was to identify the effects of EMLA cream (eutectic mixture of local anesthetics, lidocaine and prilocaine) on pain during ampicillin sodium intradermal (ID) skin test, and also to assess skin reaction after the skin test. Methods: Forty-three nurse-volunteers had skin tests with 0.01ml-0.05ml ampicillin sodium antibiotics. Skin tests were done on each forearm to compare the pain level of the skin test site after application of EMLA cream with the pain level when no EMLA cream was applied. EMLA cream was applied at the ID skin test site with an occlusive dressing for one hour. Pain was evaluated using a visual analogue scale and pain sensation using the short form McGill Pain Questionnaire. The transverse diameter of the wheal and redness was read right after and at 15 minutes after the skin test. The results were compared using independent t-tests. Results: Pain score and sensation with EMLA cream treatment were significantly lower than when EMLA cream was not applied. There was no difference in skin reactions; reading of the skin test was not affected by EMLA cream. Conclusions: EMLA cream was found to be an effective local anesthetic to relieve the pain of clients having ampicillin sodium antibiotics ID skin tests.

Purposes: Venipuncture is one of the most painful and frequently performed invasive procedure for children by nurses. The purpose of this study was to investigate the effect of EMLA cream(eutectic mixture of local anesthetics: 2.5% lidocaine and 2.5% prilocaine) to decrease venipuncture related pain and anxiety in children. Methods: A randomized, double blinded, placebo-controlled study was conducted. Sixty children scheduled venipuncture were recruited, and randomly allocated to receive either EMLA or a placebo cream 1 hour before venipuncture. Venipuncture was carried out by one nurse investigator. Pain and anxiety was measured by parent, nurse investigator, and nurse observer. Results: Pain in the EMLA group was significantly lower than that of placebo group. However, there was no significant difference in anxiety score between the EMLA and placebo groups. Local side effect of EMLA cream were negligible. Conclusions: EMLA cream was found to be an effective local anesthetic for pediatric venipuncture pain. Further studies should continue to evaluate the facilitators and barriers of EMLA cream application in pediatric nursing practice.

This study was conducted to compare the severity of cannulation pain in hemodialysis patients after topical application of EMLA cream and local injection of lidocaine and evaluated side effects and problems accompanied by the former. Twenty patients, who were on hemodialysis from September 1 to October 15, 1994 at the Kangnam St. Mary's Hospital, Catholic University Medical College, were divided into two groups of ten. To conduct a cross over study, two groups were placed on four repeated methods with lidocaine followed by four repeated methods with EMLA cream and vice versa, respectively, while the severity of cannulation pain was being measured according to a Visual Analogue Scale with each methods. The results are follows : 1) The scale of pain was recorded as $4.56{\pm}1.38$ and $2.05{\pm}1.36$ points for methods with lidocaine and EMLA cream, respectively, indicating the less severe pain with EMLA cream. 2) Local side effects such as itching(4 cases, 5.0%)and pallor (5 cases, 6.3%)were observed with methods with EMLA cream but disappeared before the completion of hemodialysis. 3) Problems associated with local lidocaine were pain at the injection of anesthetic (27cases, 16.9%)and fear for needle insertion(6 cases, 3.8%). The most frequent problems with EMLA cream application were an inconvenience in use (11 cases, 6.9%)and tedious long pretreatment time(11 cases, 6.9%), those associated with inconvenience in cream applying procedures. 4) Twelve out of twenty patients(60.0%) responded with yes to a continued use of EMLA cream in spite of problems with cream application and economical difficulties in purchasing. These results indicate that 5% EMLA cream used as a local anesthetic in hemodialysis significantly reduces cannulation pain and lacks side effects, thus serving as a suitable method for the alleviation of cannulation pain and inconvenience in hemodialysis and the relief of psychological stress of nurses.

Purpose: Although Hydrofluoric acid(HF) is not a strong acid when compared to other hydrogen halides, it is a feared corrosive and is particularly dangerous at higher concentrations. HF burns are characterized by symptoms, often delayed and localized with diluted HF solutions, to include erythema, edema and severe pain. Pain, a well known symptom following exposure to calcium binding. And, EMLA$^{(R)}$ cream is a topical formulation based upon the eutectic mixture of lidocaine and prilocaine and is used in clinical settings to provide pain relief undergoing superficial surgical procedures. The aim of this study is to evaluate effects of EMLA$^{(R)}$ cream, pain - control dressing on the treatment for HF injury wound. Methods: From June 2007 to June 2008, this study was carried out with 10 patients who had HF partial thickness burns. We were applied topically EMLA$^{(R)}$ cream to injured wound with vaseline gauze and 10% calcium gluconate wet gauze dressings. As a principle, in the emergency treatment, partial or complete removal of the bullae along with copious washing with normal saline was done, depending on the degree of HF invasion of the distal digital extremities. The effect of dressing was investigated by visual analogue pain scale. Results: We therefore reviewed 10 cases of HF - induced pain and pain relief treatment principle. The 10 cases who came to the hospital nearly immediately after the injury healed completely without sequelae and EMLA$^{(R)}$ related complications. Conclusion: Proper initial treatment of HF burns are important, if not promptly recognized and properly treated, for produce serious injury. Topical EMLA$^{(R)}$ cream remain a powerful, new advancement for minimizing HF - related pain during dressing procedures. When used appropriately, topical EMLA$^{(R)}$ cream can provide a safe and effective alternative to other forms of HF - pain control treatment.

Purpose: This study aimed to compare the effects of three interventions on pain, blood pressure, and pulse rate during infiltration anesthesia in patients about to undergo gamma knife surgeries. Methods: The three interventions employed in a university-affiliated Hospital in J City, South Korea were as follows: EMLA cream plus Vapocoolant spray (Vapocoolant, n=30), EMLA cream plus 10.0% Lidocaine spray (Lidocaine, n=30), and EMLA cream only (EMLA, n=30). The equivalent control-group pre test - post test study design was used. Pain was assessed subjectively using the numeric rating scale (NRS) and objectively using a Galvanic Skin Response (GSR) tester. NRS scores were assessed after infiltration anesthesia and the GSR was assessed during infiltration anesthesia. Blood pressure and pulse rate were assessed twice: before and after infiltration anesthesia. Data were collected between August 3, 2016 and March 24, 2017. Results: NRS scores after infiltration anesthesia and the GSR during infiltration anesthesia were significantly lower in the Vapocoolant group than in the Lidocaine and EMLA groups (F=13.56, p<.001 and F=14.43, p<.001, respectively). The increase in systolic blood pressure (F=4.77, p=.011) and in pulse rates (F=4.78, p=.011) before and after infiltration anesthesia were significantly smaller in the Vapocoolant group than in the Lidocaine and EMLA groups; however, no significant differences were observed in diastolic blood pressures (F=1.51, p=.227). Conclusion: EMLA cream plus Vapocoolant spray was the most effective intervention to relieve pain and to lower increase in systolic blood pressure and pulse rate caused by infiltration anesthesia for stereotactic frame fixation. Thus, application of Vapocoolant spray in addition to EMLA cream is highly recommended as a nursing intervention for patients undergoing gamma knife surgeries.

이 연구의 목적은 도포마취제로서 5% EMLA cream과 20% Benzocaine gel의 구강 내 주사침 자입 및 마취제 주입시 전/구치부 전정부와 구개부에서의 작용시간과 동통 감소 효과를 평가하기 위함이다. 두 가지 도포마취제는 양측성 무작위 단일 맹검법 분할 디자인으로 평가되었다. Phase I은 전/구치부 전정부와 구개부에 도포마취제를 도포한 후 각각의 도포마취제의 작용시간을 평가하였다. Phase II는 Phase I에서 측정된 시간을 기초로 각각의 도포마취제를 부위별로 적용하여 주사침 자입 및 마취제 주입시 동통 감소 효과를 평가하였다. 평가를 위해 100-mm modified visual analog scale(VAS)를 이용하여 주관적인 동통 수치를 기록하였고, 맥박산소측정기(Pulse oximeter)를 사용하여 주사침 자입 및 마취제 주입 전후의 맥박수를 관찰하여 객관적인 동통 감소 효과를 비교하였다. Phase I 실험결과 두 가지 도포마취제는 전치부가 구치부보다, 구개부가 전정부보다 더 긴 작용시간을 보였다. 전치부 구개부를 제외한 모든 부위에서 EMLA cream이 Benzocaine gel보다 더 빠른 작용시간을 보였다. Phase II 실험결과 마취제주입시 부위별 그룹에 따른 VAS Score를 보면 전치부와 구치부 구개부에서 EMLA cream이 Benzocaine보다 동통 감소 효과에 있어 유의한 차이를 보였다(p<.05). 결론적으로 EMLA cream은 Benzocaine보다 전정부와 구개부 모두에서 빠른 작용시간과 더 좋은 유지력을 나타냈다. 또한 EMLA cream은 Benzocaine보다 주사침 자입시 전치부 구개부를 제외한 모든 부위에서, 마취제 주입시 전치부와 구치부 구개부에서 Benzocain 에 비해 더 좋은 동통 감소 효과를 보였다.

우리나라 질병관리본부는 전염병 예방을 목적으로 국가 필수 예방접종을 정하여 특정 시기에 접종하도록 권장하는데, 대부분의 예방접종이 만 2세 전에 집중되어 있어 필수 예방접종만 투여 받더라도 영아는 14~20회 정도 접종을 받게 된다. DPT (diphtheria, pertussis, and tetanus) 는 제2군 법정전염병인 디프테리아, 백일해, 파상풍 예방을 목적으로 생후 2, 4, 6, 18개월 영아에게 근육주사하게 된다. 근육주사 시 주사 바늘 천자 및 약물 주입에 따른 통증이 유발되는데, 본 연구는DPT 예방접종을 받는 2, 4, 6개월 영아 49명을 대상으로 예방접종 시 유발되는 통증경감을 위해 국소마취용 크림인 EMLA (eutectic mixture of local anaesthetics)와 냉각 스프레이의 통증경감 효과를 조사하였다. 연구 결과 EMLA 적용군이 대조군과 냉각 스프레이 적용군에 비하여 주사 전후 맥박수와 산소포화도에 변화가 거의 없어 생리적 반응에서 통증경감 효과가 있는 것으로 나타났다. 결론적으로 EMLA 적용 군이 통증반응에 대한 생리적 변수, 즉 맥박수와 산소포화도를 정상범주로 유지하는데 있어서 냉각스프레이보다 더 효과적인 중재로 검증되었으므로 향후 DPT 예방접종 시 EMLA 크림의 적용 가능성을 시사하는 바이다.

최근 소아과 영역에서 통증 완화를 위해 사용되기 시작한 통증 완화용 연고 제재인 EMLA를 영아의 예방 접종시에 사용함으로써 영아의 통증 완화 효과를 알아 보기 위해 영남대학교 의과대학 부속병원 육아 상담실에서 DPT 예방 접종을 시행한 2개월에서 8개월 사이의 영아 80명을 대상으로 하여 통증 완화용 연고제를 사용한 40례(남아 25례, 여아 15례)와 사용하지 않은 40례(남아 21례, 여아 19례)로 나누어 비교 관찰하였다. 통증에 대한 반응을 McGrath's face scale과 Oucher pain scale, MBPS로 비교 관찰하였으며, 접종후 울음 시작 시간, 첫 울음 지속 시간, 총 울음지속 시간 등을 비교하여 다음과 같은 결과를 얻었다. 1) 대상 환아의 성별이나 연령의 분포상의 차이가 보이지 않았다.(EMLA 사용군의 평균 연령 : $4.0{\pm}0.2$개월, 대조군 : $4.5{\pm}0.8$개월) 2) 통증의 정도는 McGrath's face scale(p<0.05), Oucher pain scale(p<0.05), MBPS(p<0.01)을 이용하여 측정한 결과 EMLA 사용군에서 대조군에 비해 유의한 통증의 감소를 볼 수 있었다. 3) 주사후 첫 울음 시작 시간의 경우 EMLA 사용군에서도 $2.1{\pm}1.3$초, 대조군에서도 $2.0{\pm}0.9$초를 보여 차이가 없었으나, 평균 첫 울음 지속 시간의 경우 EMLA 사용군에서는 $6.9{\pm}4.0$초 대조군에서는 $14.2{\pm}9.2$초를 보여 현저한 감소를 보였다.(p<0.05) 평균 총 울음 지속시간의 경우도 EMLA 사용군에서 $9.8{\pm}6.0$초, 대조군에서 $21.9{\pm}12.8$초로 EMLA 사용군에서 현저한 울음 시간의 감소를 보였다.(p<0.05) 4) 부작용으로는 일시적 발작이 5례에서만 관찰되었다. 국소마취 연고를 영아에 대한 예방접종시에 사용함으로써 부작용 없이 통증이 완화되는 것을 관찰하였다. 그러나 EMLA 연고로 통증이 완화될 뿐 완전히 없어지는 것이 아니고, 연고 제재의 효과발현을 위하여 1시간 동안 부착하여야 하는 불편과 연고의 비용이 고가인 점 등의 문제점이 있어 예방접종시에 일상적으로 사용하기에는 아직 현실적으로 부적당하다고 생각되었다.
