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.

To evaluate the effect of a new topical anesthetic cream (EMLA: Eutectic mixture of local anesthetics) on reducing pain associated with DPT vaccination, we conducted a clinical observation on eighty infants who were brought to well baby clinic of Yeungnam University Hospital for DPT vaccination. 80 Infants, who were between 2 months and 8 months in age, were divided into two groups. EMLA treated group and control group. Male to femle sex ratio was 1.4 to 1. EMLA cream was applied 60 minutes before DPT vaccination, the effect of reducing pain was assessed by using McGrath's face scale, Oucher pain scale and modified behavioral pain scale (MBPS) and also evaluated by measuring the duration and time of crying (the time of the first crying after injection, duration of the first crying, total duration of crying). The scores of those scales were lower in EMLA treated group than in control group significantly (P(0.01 in McGrath's face scale, MBPS and p<0.05 in Oucher pain scale). There was no difference in the time of the first crying after vaccination in both groups. The duration of the first crying was shorter in EMLA treated group than control group of crying was also shorter in EMLA treated group (EMLA treated group $9.0{\pm}6.0$ sec, control group $21.9{\pm}12.5$ sec, p<0.05). Transient skin erythema was noted in 5 infants after EMLA application, but no other adverse effects were observed. We conclude that the application of EMLA cream before vaccination seems to be an effective and safe way to reduce the pain from vaccination, but it takes usually 60 minutes to get the anesthetic effect of EMLA and it is expensive, so EMLA cream can not be recommended in routine vaccination in infants now.

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.

This study aimed at identifying the effect of vapocoolant spray and EMLA (eutectic mixture of local anesthetics) cream upon DPT (diphtheria-pertussis-tetanus)vaccineassociated injection pain in infants. A nonequivalent control group pretest-posttest design was used. The subjects were 49 infants, 19 of them for control group, 15 of them for vapocoolant group, and 15 infants for EMLA group. Pulse and oxygen saturation as pain indicators were measured before and after DPT vaccination. FLACC was also measured after vaccination. The data were collected between October 2009 and June 2010 and analyzed using SPSS WIN 20.0. EMLA group had significant a little changes in pulse (F=43.37, p <.001) and oxygen saturation (F=9.86, p=.003) compared to the control and vapocoolant group. But there was no difference in FLACC pain score among three groups. This results showed that EMLA cream is an effective agent for reducing DPT vaccination-associated pain. Therefore, EMLA cream can be used to reduce pain at public health centers and clinical settings.

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.

Purpose: The purpose of this study was to identify effects of EMLA (Eutectic Mixture of Local Anesthetics) cream application on pain perception and pain response during insertion of implanted venous access port needle in children with cancer. Methods: From December 2010 to August 2011, at U university hospital, 20 patients scheduled for implanted venous access port needle insertion were recruited, and randomly assigned to receive either EMLA or a placebo cream 1 hour before the implanted venous access port needle insertion. While conducting needle insertion, changes in pulse and oxygen saturation on the pulse oxymeter monitor were measured and pain behavior reaction was also measured during needle insertion in the treatment room. After conducting needle insertion, self-reported pain reaction, and mothers' perception of the children's pain reaction were measured. Collected data were statistically processed using SPSS version 17.0 for Windows, and analyzed using descriptive statistics, t-test. Results: Children's self-reported degree of pain, degree of pain as perceived by mothers and pain behavior reaction decreased significantly in the EMLA application group compared with the placebo group. Conclusion: Findings indicate that application of EMLA cream is effective in relieving pain in these children during implanted venous access port needle insertion.

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.

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.
