Background: Advantages of paramedian approach over midline approach include less tissue trauma and less dependence on patient's ability to assume a fetal position. When midline approach fails in patients who are difficult to take a position with lumbar spine flexed, paramedian approach to interlaminar space may succeed. Methods: Success rates of spinal anesthesia were measured for 47 flexed patients by midline approach, 48 flexed patients by paramedian approach, 23 straightened patients receiving spinal anesthesia by midline approach, and 23 straightened patients by paramedian approach. Results: Success rates in flexed patients were 100% by midline approach and 100% by paramedian approach. Success rates for straightened patients were 13.0% by midline approach and 78.3% by paramedian approach. For straightened patients there were no correlations between success fate and age, weight, Ponderal Index but there were correlations between height and midline approach of spinal anesthesia. Conclusion: Pertaining to adult Koreans, success rates of spinal anesthesia for strainghtened patients were less than those for flexed patients. Success rate of paramedian approach of spinal anesthesia among strainghtened patients were better than those of midline approach.

From Jan. 1981 to Dec. 1991, we had treated 25 patients with congenital coronary art-eriovenous fistulas [CAVF] in Seoul National University Hospital. A retrospective review was made to delineate the course and the management of CAVF and to clarify the role of surgical treatment. Fifteen patients were male and 10 were female with The mean age of 17.4 years[from 3 months to 58 years]. The most frequent symptom was dyspnea on exertion[56%]. Other symptoms were angina and palpitation. Sixty-eight percent of the patients were symptomatic. Fifty-three percent of patients less than 20 years old were symptomatic and 100% of patients over 20 years old were symptomatic. Three patients had multiple CAVFs. The fistula drained into the right ventricle in 13, pulmonary artery in 9, left ventricle in 4, right atrium in 2, and left atrium in 1. Thirteen patients had other associated cardiac lesions. The mean pulmonary-to-systemic blood flow[Qp /Qs] in the isolate CAVF group was 2.19. All patients were operated on to correct the fistulas and other associated cardiac lesions. All patients were followed from 1 month to 11 years without late death. Postoperative complication rate was 24% -significant arrhythmia [3], recurred CAVF[1], psychosis[1], pneumonia [1]. Symptomatic improvement was evident postoperatively. Below 20 years old, 94% of patients were asymptomatic, but above 20 years old, symptoms persisted in 25%. In summary, early elective repair of CAVF is indicated in all patients because of higher complication rate and frequent persistent symptoms in older patients.

The Free fatty acid [FFA] induced massive erythrocyte crenation has been reported in patients undergoing extracorporeal circulation[EGG], suggesting that the crenated cells impair microcirculatory flow and tissue oxygenation during and after the operation. Effect of albumin administration on erythrocyte crenation was examined in 24patients undergoing open heart surgery at the department of Thoracic and Cardiovascular Surgery in the Kyung Hee University Medical Center Between January, 1989 and August, 1989: 8 patients of 24 patients [group A] were given 50 gm albumin, another 8 patients of 24 patients [group B] were g en 26 gm of albumin and the other 8 patients of 24 patients [group C] were not given any albumin as a part of the priming solution. Erythrocyte crenation was almost completely prevented in the patients given 50 gm albumin. Crenated erythrocytes d urging ECC were 3.6* 0.4 % [mean\ulcornerD] of all erythrocytes and 3.1*0.6% after ECC. This was significantly lower than in patients without albumin administration [64.2*9.5% during ECC and 28.7*1.9% after ECC]. But the effect was less striking in the patients given 25 gm albumin, 37.8* 12.0 % during ECC and 27.8*3.9 % after ECC. Maintaining an adequate level of plasma albumin is important in preventing erythrocyte crenation during ECC, improving microcirculatory flow in patients undergoing open heart surgery.

One hundred eighty-eight patients[August.23,1988,through July.30,1994 underwent aortic[AVR , mitral[MVR , or double [DVR valve replacement with the St.Jude Medical prosthesis. The author analyzed 100 patients with valvular heart disease,who underwent valve replacement with the St.Jude Medical prothesis from 1990 to 1994, at Hanyang University hospital Cardiovascular department. Information on volume and functional change of the heart chamber can be obtained by cardiac echocardiography and cartheterization. Out of 100 patients, 40 patients were male[40% and 60 patients were female [60% . Age ranged from 13 years to 68 years, with mean age of 42.6 years. Mean height was 160.3cm and mean body weight was 54.9Kg. According to NYHA functional classification, class III is most frequent and 60 patients could be classfied under it. MVR [involved Redo MVR was performed in 40 patients, AVR [involved Redo AVR was performed in 18 patients, and DVR [involved Redo DVR was performed in 42 patients. Warfarin [Coumadin anticoagulation was recommended for all patients. Life long warfarin anticoagulation was necessary to all patients who underwent valve replacement with St.Jude Medical prosthesis. Ideal prothrombin time was maintained about 30% during warfarinization. There were no case of mechanical failure. It followed a comparison of echocardiography before and after valve replacement at Hanyang University hospital [30 patients and a preoperative evaluation of cardiac catheterization and angiography [64 patients . The St.Jude Medical cardiac valve is a viable alternative in the surgical therapy of valvular heart disease.

Purpose: Paraquat, a globally used herbicide, is highly toxic to human beings. Hence, we reviewed some cases of paraquat poisoning in Korea. Methods: We analyzed the clinical and laboratory findings of 50 patients poisoned with paraquat retrospectively. The patients were admitted to the department of internal medicine in the Eumseong KeumWang hospital from January 2008 to December 2008. Results: Among 50 cases of paraquat poisoning, 28 cases were male. Twenty-four cases (48%) were over 60 years old. Fourty-nine patients ingested paraquat on purpose as suicidal attempts, while 1 patient underwent accidental ingestion. Seven patients swallowed less than one mouthful of paraquat, of which 4 patients survived. Eleven patients swallowed two mouthfuls of paraquat, of which 8 patients survived. Thirty-two patients swallowed over three mouthfuls of paraquat and they all died. Thirty-one patients with leukocytosis died. Twenty-one patients with metabolic acidosis died. Increased levels of blood amylase and glucose were related to high mortality, and increased level of blood creatinine was related to severe mortality. Hemoperfusions were accomplished in 27 patients of paraquat poisoning, of which 12 patients survived. Conclusion: Paraquat is a highly toxic herbicide. When patients arrive at the hospital, laboratory findings, urine paraquat concentrations, arrival time, and the amount of paraquat consumed must be considered for treatment plan.

Purpose: We evaluated the clinical outcomes of the non-operative management of post-gastrectomy duodenal stump leakage in patients with gastric cancer. Materials and Methods: A total of 1,230 patients underwent gastrectomy at our institution between 2010 and 2014. Duodenal stump leakage was diagnosed in 19 patients (1.5%), and these patients were included in this study. The management options varied with patient condition; patients were managed conservatively, with a pigtail catheter drain, or by tube duodenostomy via a Foley catheter. The patients' clinical outcomes were analyzed. Results: Duodenal stump leakage was diagnosed in all 19 patients within a median of 10 days (range, 1~20 days). The conservative group comprised of 5 patients (26.3%), the pigtail catheter group of 11 patients (57.9%), and the Foley catheter group of 3 patients (15.8%). All 3 management modalities were successful; none of the patients needed further operative intervention. The median hospital stay was 18, 33, and 42 days, respectively. Conclusions: Non-operative management of duodenal stump leakage for selected groups of patients with gastric cancer was effective for control of intra-abdominal sepsis. This management modality can help obviate the need for surgical intervention.

A total of 55 patients underwent surgical managements for postintubation tracheal stenosis from July 1975 through March 1997. All but 8 had received ventilatory assistance. The patients had S cuff lesions, 17 stoma lesions, 7 at both levels, 5 at subglottic lesions. Thirty two patients underwent the sleeve tracheal resection and end-to-end anastomosis. Five patients performed a wedge resection and end-to-end anastomosis. Twenty two patients received the Montgomery T-tube for relief of airway obstruction. Simple excision of granulation tissue was done in 7 patients. Rethi procedures(anterior division of cricoid cartilage, partial wedge resection of lower thyroid cartilage and T-tube molding) were performed in 2 subglottic stenosis patients. And the other subglottic patient was received permanent tracheal fenestration at 1975. The tracheoesophageal fistula patient was done sleeve tracheal resection and end-to-end anastomosis with interrupted double layer closure of esophageal fistula site. Cervical approach was used in 49 cases, cervicomediastinal in 13 cases and median stemotomy In 6 cases. Techniques for obtaining tension-free anastomosis included a cervical neck flexion(15-30$^{\circ}$) in all sleeve resection patients and laryngeal release in one. The length of resection was 1.5 to 5.0 on A total of 41 patients(74.5%) had good(24 patients) or satisfactory(17 patients) results. But in ten cases, the restenosis of anastomosis site which is the most common complication was developed Two of them underwent a second reconstruction and 8 patients required T-tube insertion for airway maintenance. Three patients(5.4%) died. The causes of death were tracheo-innominate artery fistula(2) and sudden obstruction of airway(1).

Background: Patients with disabilities often require general anesthesia for dental treatment because of their cooperative or physical problems. Since most patients with disabilities take central nervous system drugs, the management of recovery status is important because of drug interactions with anesthetics. Methods: The anesthesia records of patients under general anesthesia for dental treatment were reviewed, and data were collected. Healthy patients under general anesthesia for dental phobia or severe gagging reflex were designated as the control group. Patients with disabilities were divided into two groups: those not taking any medication and those taking antiepileptic medications. The awakening time was evaluated in 354 patients who underwent dental treatment under general anesthesia (92 healthy patients, 183 patients with disabilities, and 79 patients with disabilities taking an antiepileptic drug). Based on the data recorded in anesthesia records, the awakening time was calculated, and statistical processes were used to determine the factors affecting awakening time. Results: Significant differences in awakening time were found among the three groups. The awakening time from anesthesia in patients with disabilities (13.09 ± 5.83 min) (P < 0.0001) and patients taking antiepileptic drugs (18.18 ± 7.81 min) (P < 0.0001) were significantly longer than in healthy patients (10.29 ± 4.87 min). Conclusion: The awakening time from general anesthesia is affected by the disability status and use of antiepileptic drugs.

Objectives: To lay the foundation for future research into Korean Medicine treatment for Rotator Cuff repair surgery patients by analyzing Korean Medical and Western Medical service utilization and treatment duration. Methods: Data sampling was performed on 2015's HIRA patient data (confidence level of 97%) to analyze patients' Korean Medical and Western Medical service usage tendency. Sampled groups were divided into two groups: i) Patients who completed their treatment within five months after the rotator cuff surgery (termination group), ii) Patients who were treated for more than five months after the surgery (continuation group). Then the patients' Korean Medical and Western Medical service usage tendency was investigated and information of these patients are arranged. Results: Out of 1,453,486 patients who were gathered for sampling, 2,461 patients in total had gone through rotator cuff repair surgery. The termination group had 517 patients and the continuation group had 541 patients. The proportion of patients who visited a Korean Medicine clinic was lower in the termination group than the continuation group. Conclusion: The continuation group received more treatments (both in Western Medicine and Korean Medicine) and spent more on medical expenses compared to the termination group. Further research is highly recommended for more efficient Western Medicine and Korean Medicine treatments and reduced medical expenditure.
