지속적 통증조절기를 이용한 경막외강으로 Fentanyl을 첨가한 0.125% Ropivacaine과 0.125% Bupivacaine주입시 분만통 조절에 대한 효과
최정환,이해진,성춘호 대한통증학회 2000 The Korean Journal of Pain Vol.13 No.1
Background: This study intends to evaluate the benefits of the administation of continuous infusion and demand doses of 0.125% ropivacaine compared with 0.125% bupivacaine after addition of fentanyl using patient controlled epidural analgesia (PCEA) for pain control during labor. Methods: Thirty-nine American Society of Anesthesiologists physical status 1 or 2 parturients were randomized by double blind design to receive either 0.125% bupivacaine with fentanyl 1ug/ml or equivalent concentration of ropivacaine/fentanyl using PCEA; with 6~8 ml/hr basal rate, 3 ml bolus, 5 min lockout, 30 ml/hr dose limit. We assessed analgesia, the amount of study solution used in PCEA, sensory levels, motor block (0~3 scales), side effects and patient satisfaction. A postpartum questionnaire was carried out afterward. Results: There were no differences in visual analogue scores (VAS) for pain, hourly study solution use, sensory levels, side effects and patient satisfactian between groups. However, patients administered ropivacaine/fentanyl had significantly less demand, less administered in PCEA, less numbness and restriction of movement compared with patients in the bupivacaine/fentanyl group. Conclusions: Ropivacaine 0.125% with fentanyl, when administerd epidurally by PCEA for labor analgesia, was equally efficious as bupivaciane 0.125% with fentanyl, having with minimal numbness and restriction of motion.

Gout tophus is most commonly found in the lower extremities such as toes and ankles. The auricle is a rare site for gout tophi. Although auricular tophus (AT) is not life threatening, it is important because it can be misdiagnosed as other diseases including malignancy. ATs are firm deposits of crystallized uric acid, which may gradually grow at the subcutaneous layer of the auricle. ATs can be treated with dietary modification and medication for a long time. When pain persists, cosmetic deformity is concerned, or prompt resolution of those symptoms are required, surgical excision is worth considering. Here, we report the case of a patient presenting with multiple bilateral auricular painful nodules. Thorough questioning regarding medical history revealed that the patient had a history of untreated gout. Histopathological examination confirmed the diagnosis of AT. So, we report this case with review of literatures.
Regular Insulin을 토끼에 정주시 마그네슘 전처치가 혈중 칼륨농도와 혈역학적 변동에 미치는 영향

Background : Insulin is known to act as second effector that provides potassium transfer from extracellular fluid to intracellular fluid, thus causing hypokalemia and arrythmia. We evaluated the effect of magnesium sulfate treatment on hemodynamics and serum potassium concentration, induced by continuous infusion of regular insulin solution in rabbits. Method : Twenty-four rabbits were divided into four groups for the experiment. Group I was given intravenouse injection of 5 ml of normal saline and continuous dripping of 7.5 U of RI. Group II was pretreated with 30 mg/kg of magnesium sulfate, followed by continuous dripping of 7.5 U of RI. Group III was given 5 ml of normal saline and 15 U of RI. And Group IV was administered 15 U of RI after 30 mg/kg of magnesium sulfate pretreatment. Venouse blood sampling was done before pretreatment, and after 5, 30, 60 and 120 minutes respectively. Heart rate and arterial blood pressure were taken at the same intervals. Result : 1) There was no significant change in serum potassium concentration in groups injected with 7.5 units of RI respectively (groups I and II), regardless of magnesium pretreatment. But in groups injected with 15 units of RI, the group that was not pretreated with magnesium (Groups III) showed a decrease in serum potassium concentration from 3.39 0.57 Eq/L to 2.29 0.71 mEq/L, while the concentration in the pretreated group (Group IV) decreased more significantly from 3.35 0.50 mEq/L to 1.81 0.41 mEq/L. 2) Pulse rate did not change significantly in groups that received continuous infusion of 7.5 units of RI (groups I and II) regardless of magnesium pretreatment, but increased significantly in groups injected with 15 units of RI (groups III and IV), pretreated or not. The pretreated group (group IV) had a more significant rise in pulse rate compared with the group that was not pretreated (group III). 3) In all of the groups, those pretreated with magnesium (groups II and IV) and those not pretreated (groups I and III), there was no significant change in systolic and diastolic blood pressures. Nor was arrhythmia detected. Conclusion: The above results indicate that while magnesium sulfate pretreatment at 30 mg/kg with insulin infusion affects serum potassium concentration, has an antiarrhythmic effect, and may induce tachycardia, it does not have any significant effect on blood pressure.

The purpose of this study was to analyze a perception of the Physically handicapped students on the physical education class. The results were as follows: Descriptive statistics analyses revealed that approximately 74%(male), 45%(female) of the students is reported that they like PE. A total of 463 response on the open-ended question were content-analysed. 5 positive experience and 3 negative experience were emerged: In positive experience, (1) PE provides health and rehabilitation, (2) experience of versatile activity, (3) PE is fun and enjoyable, (4) PE provides close relationship with friends and teacher. In negative experience, (1) interuptive for physical disability, (2) lack of management skill, (3) educational environment

Lateral medullary syndrome, also known as Wallenberg syndrome, is characterized by sensory deficits affecting the trunk and extremities on the opposite side of the lesion, and the face and cranial nerves on the same side of the lesion. Other clinical symptoms and findings are dysphagia, slurred speech, ataxia, facial pain, vertigo with nystagmus, Horner’s syndrome, diplopia, and possibly palatal myoclonus. The cause of this syndrome is usually occlusion of the posterior inferior cerebellar artery or vertebrobasillar artery. We observed a case of Wallenberg syndrome occuring secondary to the cavernous malformation and initially presenting as unilateral vocal cord palsy. The centrally-medicated vocal cord palsy is a rare cause of hoarseness, but should be considered in cases where no other local cause can be found.
