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.

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 : The aims of this study were to test the efficacy of vapocoolant spray to decrease the symptoms associated with pain in newborns undergoing heel stick and intramuscular injection and compare the pain relief effect of oral glucose. Methods : Randomized, controlled study including sixty newborns undergoing heel stick and intramuscular injection. Group 1 was heelsticked, Group 2 was intramuscular injected, Group A did not recieve any treatment, Group B recieved 30% glucose solution orally, Group C was applied vapocoolant spray symptoms and signs associated with pain at heel stick and intramuscular injection were measured with the premature Infant Pain Profile (PIPP) scale. Results : There was no significant difference in the PIPP score between intramuscular injected group control and heel stick group control (P=0.07). The mean PIPP score of Group 1A (control) $10.6{\pm}2.4$, Group 1B $5.5{\pm}2.0$, Group 1C $5.2{\pm}1.8$. The mean PIPP score 1B and 1C were significantly lower than control (1B P<0.001, 1C P<0.001). The mean PIPP score of Group 2A (control) $12.5{\pm}1.4$, Group 2B $7.0{\pm}1.7$, Group 2C $6.4{\pm}1.6$. The mean PIPP score 2B and 2C were significantly lower than control (2B P<0.001, 2C P<0.001). Conclusion : The antinociceptive effect of vapocoolant sparay is as effective as 30% oral glucose solution for pain control. So this study support the use of vapocoolant spray for reducing pain during painful procedure in the neonatal intensive care units.

근막동통은 발통점과 중추흥분효과가 나타나는 국소적 근육성 동통이다. 발통점은 근육의 일부나 건 부착점에 나타나는 부위로서 단단한 띠로서 느껴지고 촉진시 통증을 유발한다. 통증은 관련된 발통점의 위치에 따라 연관된 부위에 나타난다. 이러한 근막 발통점에 따른 증상은 약한 기능이상부터 일상생활이 어렵게 되는 정도의 심한 통증까지 다양하다. 이의 발생에는 국소적 근육이상, 심부 동통, 심리적 스트레스의 증가, 수면장애와 전신적인 요인들도 관여한다. 일반적으로 치료는 보존적인 처치로써, fluoro-methane 같은 vapocoolant spray를 사용하는 사용하여 분사신장하는 방법이 있으며, 국소적인 주사, 마사지, 초음파, 온열요법등이 있다. 여러 환자에서 근막동통을 가지는 환자에 분사신장요법을 시행한 결과 대부분 환자에서 증상의 개선을 보였다. 근막동통의 치료시 분사신장요법은 매우 보존적인 처치로 임상가의 적용과 접근이 쉬우며, 환자로 하여금 치료에 따른 불안감을 줄이면서 만족을 느낄 수 있는 치료로 사료된다. 그러나 만성 환자의 경우 분사신장요법의 치료결과에 대한 만족도가 높지 않았다. 분사신장 용법은 근막동통을 가진 환자 모두에서 효과적이지는 않으나 치료의 도입으로, 근막동통을 진단시에 일차적으로 사용할 수 있는 안정한 보존적인 용법으로 사료된다.
