본 연구는 초고속망에서 한방원격 검진시스템을 개발하는데 있어서 필요한 한의학 의료정보 검색을 위한 시소러스를 생성하였다. 이를 통해 한의학 처방에 따른 탕재별, 약재별, 구분별, 병증별 지능형 검색이 웹 상에서 가능하도록 구현하였다. 본 검색기를 통해 한의사는 처방에 따라 필요한 탕재 정보와 약재의 정량정보를 자세히 검색할 수 있으며, 일반 사용자(환자)는 개인별 병증에 대한 손쉬운 한의학 정보 서비스의 원격지 검색이 가능하다.

Acquired digital fibrokeratoma is a rare form of benign tumor of the fibrous tissue involving the skin. Histopathologically, the epidermis shows marked hyperkeratosis and acanthosis. The core of lesion is formed by thick, interwoven bundles of collagen predominantly oriented in the direction of the vertical axis of the lesion. We report a case of acquired digital fibrokeratoma in a 50-year-old female who has given consistent trauma on finger tip for com removal. (Korean J Dermatol 2002; 40(3): 306~308)

Background: Intravenous anesthetics causes depression of ventilatory response to hypercapnea. Doxapram stimulates ventilation via peripheral and central chemoreceptors. This study was aimed to evaluate the effect of doxapram on ventilation during total intravenous anesthesia (TIVA). Methods: 60 patients undergoing operation under spontaneous ventilation via laryngeal mask airwaywere randomly divided into 3 groups: Control group received 5% dextrous infusion, D-2 group received doxapram injection of 1 mg/kg followed by continuous infusion of 2 mg/kg/hr, and D-4 group received doxapram injection of 2 mg/kg followed by continuous infusion of 4 mg/kg/hr. Anesthesia was induced and maintained with propofol and remifentanil. Respiratory rate, tidal volume (VT) and arterial carbon dioxide tension (PaCO2) were measured before and 15 min after induction of anesthesia, 0(15 min after start of operation), 1, 2, 3, 5, 15, 30, 45, and 60 min after start of doxapram infusion during TIVA. Results: VT was significantly increased 1 min after start of doxapram infusion and returned to the value of pre-doxapram infusion immediately. In D-4 group, VT was significantly (P<0.05) increased again 5 min after doxapram infusion compared with the value of pre-doxapram infusion and control group. PaCO2 was decreased 1 min after start of doxapram infusion and then increased again 2 min after doxapram infusion. In D-4 group, the degree of increase of PaCO2 was significantly (P<0.05) less than those of D-2 group. Conclusions: Doxapram injection of 2 mg/kg followed by continuous infusion of 4 mg/kg/hr improved the depression of ventilatory response during TIVA. (Korean J Anesthesiol 2007; 53: 470∼6)

Background: This study evaluated the efficacy of an epidural single dose of neostigmine combined with fentanyl to provide postoperative analgesia after radical subtotal gastrectomy. Methods: Fifty two adults patients with ASA physical status 1 and 2 are randomly allocated to receive a single injection of either epidural fentanyl 100μg or combination of fentanyl 100μg with neostigmine 250, 500 and 750μg in a total volume of 10 ml. Pain scores were recorded after 0, 5, 10, 15, 20, 30 mins to determine the onset of analgesia. Patients` vital signs as well as side effects were monitored at regular intervals. Results: Patients` demographic data were not different from each other. Epidural neostigmine 750μg with fentanyl 100μg produced effective analgesia (visual analog scale at 10 min; 35 ± 10.6 mm). The time to first rescue analgesics administration was significantly longer in the neostigmine group (250μg: 84.2 ± 9.4, 500μg: 90.9 ± 7.1, 750μg: 92.5 ± 14.4 min) than the control group (53.0 ± 20.0 min). Conclusions: Combination of fentanyl with neostigmine was proven to be more effective for treating postoperative pain after subtotal gastrectomy than fentanyl alone. Additionally, the most effective dose of epidural neostigmine was 750μg. (Korean J Anesthesiol 2007; 53: 217~21)
임상연구 : 제왕절개술환자에서 호기말 Sevoflurane 농도를 1%로 유지 시 수술전 분만통 유무에 따른 이중분광계수의 비교

Background: An end-tidal concentration of 1% sevoflurane with 50% nitrous oxide (N2O) during a Cesarean section resulted in bispectral index (BIS) values > 60, which are considered at risk for awareness. The present study aimed to determine whether the presence or absence of labor pain prior to the Cesarean section would affect the BIS value. Methods: Sixty women scheduled to undergo Cesarean section under general anesthesia, were allocated to three groups of 20 patients: women undergoing elective surgery without labor pain (group 1, control), or emergency surgery without (group 2) or with (group 3) active labor pain. After endotracheal intubation, anesthesia was maintained with end-tidal 1% sevoflurane and 50% N2O in oxygen throughout the surgery. The BIS value, systolic blood pressure and heart rate were measured before (baseline) and during the induction of anesthesia, intubation, skin incision, uterine incision, delivery and at 1, 3, 5 and 10 min after delivery. Neonatal effects were assessed using Apgar scores at 1 and 5 min after delivery. Results: BIS values were significantly lower in group 3 than in groups 1 and 2 throughout the study, except at baseline and induction (P < 0.05). However, the systolic blood pressure, heart rate and Apgar scores did not differ among the three groups. Conclusions: These results demonstrate that 1.0% sevoflurane combined with 50% N2O results in BIS values < 60 during Cesarean delivery in women with active labor pain but not in those without active labor pain, consistent with an adequate depth of anesthesia to prevent recall.
