다분절 척추관협착증에서 선택된 분절의 제한된 감압술의 효과
고영도 梨花女子大學校 醫科大學 醫科學硏究所 1998 EMJ (Ewha medical journal) Vol.21 No.1
Spinal stenosis is one of the degenerative diseases of spine, and frequently involves several segments. However, symptom may be provided by pathology in only one or two segments. Therefore, it is very important to select symptomatic segments when we treat patients with multilevel stenosis surgically. Decompression may be done limitedly to prevent high morbidity and complications associated with extensive decompression and posterolateral fusion. The purpose of this study is to evaluate the effectiveness of limited decompression of selective segments in spinal stenosis. From September, 1993 to August, 1996, 21 patients who underwent limited decompression of only symptomatic segments, were followed up for more than 1 ysar, and the results were assessed according to the criteria of Kim & Kim. The indications of surgery were definite neurologic symptoms, failure of conservative treatments, and no instability. The segments for operation were chosen by symptom, physical examination and radiographic study, and sometimes root block or electromyography were done in case of necessity. The results were followed as : 4 excellent(19%), 13 good(62%), 3 fair(14%), and 1 poor(5%). 1 superficial wound infection developed and was treated without suquelae. Conclusively, limited decompression of selective segments in multilevel spinal stenosis is considered to be useful if selection of level and extent of decomperssion are carefully determined.

Study Design: Prospective cohort study. Purpose: Evaluation of the clinico-radiological outcome and complications of limited laminectomy and restorative spinoplasty in spinal canal stenosis. Overview of Literature: It is critical to achieve adequate spinal decompression, while maintaining spinal stability. Methods: Forty-four patients with degenerative lumbar canal stenosis underwent limited laminectomy and restorative spinoplasty at our centre from July 2008 to December 2010. Four patients were lost to follow-up leaving a total of 40 patients at an average final follow-up of 32 months (range, 24–41 months). There were 26 females and 14 males. The mean±standard deviation (SD) of the age was 64.7±7.6 years (range, 55–88 years). The final outcome was assessed using the Japanese Orthopaedic Association (JOA) score. Results: At the time of the final follow-up, all patients recorded marked improvement in their symptoms, with only 2 patients complaining of occasional mild back pain and 1 patient complaining of occasional mild leg pain. The mean±SD for the preoperative claudication distance was 95.2±62.5 m, which improved to 582±147.7 m after the operation, and the preoperative anterio-posterior canal diameter as measured on the computed tomography scan was 8.3±2.1 mm, which improved to 13.2±1.8 mm postoperatively. The JOA score improved from a mean±SD of 13.3±4.1 to 22.9±4.1 at the time of the final follow-up. As for complications, dural tears occurred in 2 patients, for which repair was performed with no additional treatment needed. Conclusions: Limited laminectomy and restorative spinoplasty is an efficient surgical procedure which relieves neurogenic claudication by achieving sufficient decompression of the cord with maintenance of spinal stability.

스쿠버 다이빙 경력에 따른 무감압한계 잠수환경에서의 반복잠수가 Epinephrine, Norepinephrine 및 Dopamine 변화에 미치는 영향
소이용(So, Lee-Yong),한길수(Han, Gil-Soo),오문엽(Oh, Moon-Yeop),강명학(Kang, Myong-Hak) 한국체육과학회 2016 한국체육과학회지 Vol.25 No.1
The purpose of this study to verify the effects of repetitive dive in the No Decompression Limit(NDL) diving environment on the changes in Epinephrine, Norepinephrine and Dopamine depending on scuba diving experience. This study targeted 9 healthy adults of an unskilled group with less than 40 diving frequencies and 10 ones of a skilled group with over 40 diving frequencies. The study findings are as follows. After repetitive dive, Epinephrine decreased to 29.14% in skilled divers (p<.001) and increased to 48.34% in unskilled divers, so there was a statistically significant difference (p<.05). Norepinephrine decreased to 40.22% in skilled divers, so there was a statistically significant difference (p<.001). Norepinephrine decreased to 4.21% in unskilled divers, but there was no statistically significant difference. Dopamine decreased to 75.02% and 59.96% in skilled divers and unskilled divers respectively, so both groups showed statistically significant differences (p<.001). Norepinephrine and Dopamine declined in both skilled and unskilled groups after repetitive dive in the NDL diving environment, but Epinephrine decreased in the skilled group, while it increased in the unskilled group. This is because long stay or exercise in the cold environment led to an increase in heat production for maintaining a body temperature, the metabolic rate rose, shivering was caused by the decrease in body temperature and excessive stress lasted long during a dive.
