Background: Ketamine is widely used in infants and young children for procedural sedation and anesthesia. The aim of this study was to evaluate the efficacy and safety of low dose oral ketamine to control pain and distress in children during intravenous (IV) cannulation. Methods: This is a prospective, randomized, double-blind study, including children aged between 3 and 6 years requiring a non-emergent IV-line placement. Children were randomly assigned to two groups, treated either with oral ketamine or a placebo. All patients were monitored for vital signs. Pain was assessed using the Children's Hospital of Eastern Ontario Pain Scale (CHEOPS) and Wong-Baker Faces Pain Rating Scale (WBFS) scales and sedation using a 5-point sedation score. The facility of IV-line placement was measured by a 3-point scale. Adverse effects were recorded after 1 and 24 hours. Results: A total of 79 and 81 children were entered in the ketamine and placebo groups, respectively. The heart and respiratory rates increased significantly in the placebo group. The median CHEOPS 4 (95% confidence interval [CI]: 3, 4, P < 0.001) and WBFS 6 (95% CI: 4, 6, P < 0.001) scores decreased statistically in the ketamine group. IV-line placement was 50% easier in the ketamine group (95% CI: 37%, 63%, P < 0.001). No serious adverse effects were observed in all cases. Conclusions: Low dose oral ketamine effectively decreased the pain and distress during IV cannulation in children without any significant adverse reactions.

Purpose: The purpose of this study was to compare the effects of intravenous fluid warming and skin surface warming on peri-operative body temperature and acid base balance of abdominal surgical patients under general anesthesia. Method: Data collection was performed from January 4th, to May 31, 2004. The intravenous fluid warming(IFW) group(30 elderly patients) was warmed through an IV line by an Animec set to $37^{\circ}C$. The skin surface warming(SSW) group(30 elderly patients) was warmed by a circulating-water blanket set to $38^{\circ}C$ under the back and a 60W heating lamp 40 cm above the chest. The warming continued from induction of general anesthesia to two hours after completion of surgery. Collected data was analyzed using Repeated Measures ANOVA, and Bonferroni methods. Results: SSW was more effective than IFW in preventing hypothermia(p= .043), preventing a decrease of $HCO_3{^-}$(p= .000) and preventing base excess(p= .000) respectively. However, there was no difference in pH between the SSW and IFW(p= .401) groups. Conclusion: We conclude that skin surface warming is more effective in preventing hypothermia, and $HCO_3{^-}$ and base excess during general anesthesia, and returning to normal body temperature after surgery than intravenous fluid warming; however, skin surface warming wasn't able to sustain a normal body temperature in elderly patients undergoing abdominal surgery under general anesthesia.

본 연구는 PET(positron emission tomography) 검사를 위해 내원한 환자를 대상으로 방사성의약품 ¹⁸F-FDG 동위원소를 주사 할 때, 주사 방법과 생리식염수의 용량에 따른 주사기의 잔량의 차이를 비교하였다. 조영제를 사용하는 CT 혹은 MRI 검사 후, 3-way를 제거하지 않고, PET 검사를 위해 내원한 40명의 환자를 대상으로 ¹⁸F-FDG를 주사 할 때, 주사기와 3-way에 남게 되는 방사능을 측정하여, 실제 환자에게 투여된 방사능을 확인했다. 이때 20명의 환자들로 나누어 생리식염수의 용량을 달리하였다. 또 다른 주사 방법은 extension을 이용하여 주사 하였을 때, 주사기의 잔량 비교와 생리식염수 용량에 따른 잔량 차이를 비교하였다. ¹⁸F-FDG 를 주사 한 후, 주사기와 3-way 또는 extension에 남아 있는 방사능을 검량기로 측정하여 실제 투여된 용량을 확인 했다. 방사성의약품을 투여하기 전의 주사기의 방사능과 투여한 후 주사기와 3-way 또는 extension 의 방사능을 측정한 결과, 생리식염수 10 cc에 3way 의 주입 방식이 잔류량이 가장 낮았고, 생리식염수 10 cc에 extension, 생리식염수 5 cc에 3way 순으로 잔량이 증가하였다. 5 cc의 생리식염수에 extension 주사 방법이 잔량이 가장 많이 남아 있었다. 잔량이 가장 적게 남은 주사 방법과의 잔량 차이는 0.053 mCi이다. PET 검사 시, 3-way와 extension에 남게 되는 방사능을 감안하고, 생리식염수의 투여 용량을 조절함에 따라, 실제 환자에게 투여하고자 하는 목적 용량을 고안한다면 좀 더 정확하게 환자에게 방사성의약품을 투여할 수 있을 것이다.
