Purpose: The aim of this prospective, double-blind, randomized study was to investigate the analgesic effects of low-dose ketamine on intravenous patient-controlled analgesia (IV-PCA) with fentanyl for pain control in pediatric patients following the Nuss procedure for pectus excavatum. Materials and Methods: Sixty pediatric patients undergoing the Nuss procedure were randomly assigned to receive fentanyl (Group F, n=30) or fentanyl plus ketamine (Group FK, n=30). Ten minutes before the end of surgery, following the loading dose of each solution, 0.5 μg/kg/hr of fentanyl or 0.5 μg/kg/hr of fentanyl plus 0.15 mg/kg/hr of ketamine was infused via an IV-PCA pump (basal rate, 1 mL/hr; bolus, 0.5 mL; lock out interval,30 min). Fentanyl consumption, pain score, ketorolac use, nausea/vomiting, ondansetron use, pruritus, respiratory depression, hallucination, dreaming, and parent satisfaction with pain control were measured throughout the 48 hours following surgery. Results: The pain scores, ketorolac use, and fentanyl consumption of Group FK were significantly lower than in Group F (p<0.05). The incidence of nausea/vomiting and ondansetron use in Group FK was significantly lower than in Group F (p<0.05). There were no reports of respiratory depression, hallucination or dreaming. Parent satisfaction with pain control was similar between the two groups. Conclusion: We concluded that low-dose ketamine added to IV-PCA with fentanyl after the Nuss procedure in pediatric patients can reduce pain scores, consumption of fentanyl, and incidence of nausea/vomiting without increasing side effects.

Surveying the developmental degree of the crowns of mandibular first bicuspid in 566 korean children (264 males and 302 females) from 3 to 7 years of age by oblique cephalogram, the author got to the following results. 1. The developmental degree of the tooth crown of mandibular first bicuspid was earlier in female than in male. 2. The period of complete development of the crown of mandibular first bicuspid was 7 year 1 month in male and 6 year 3 month in female. 3. There was no significant difference in the period of complete development of the tooth crown compared with that of Japanese and American children.
小窩裂溝 塡塞材(NUVA-SEAL)에 依한 우식豫防效果에 關한 臨床的 硏究

The purpose of this study was to make a clinical evaluation of a new adhesive material (Nuva-Seal; L.D. Caulk Co.) which could protect teeth from dental caries by shielding teeth surfaces. 1. Caries prevalence after 6 months in 39 experimented lower permanent first molar was 12.82%, but 41.02% in the matched controlateral teeth. 2. After 6 months, 20.01% of test teeth had the sealant still present, 46.15% had sealant partly missing, and in 33.33% no visibly retained sealant could be detected.
