BACKGROUND: Induced hypotension is effective in decreasing blood loss and providing better visibility in the surgical field. Extensive epidural block to T4 with intravenous infusion of low-dose epinephrine allows mean arterial pressure to 50 mmHg. We investigated the effects of hypotensive epidural anesthesia comparing with normotensive epidural anesthesia during total hip arthroplasty. METHODS: 40 patients scheduled for total hip arthroplasty under epidural anesthesia were randomly divided into two groups. In hypotensive group, 0.5% bupivacaine 20cc was injected into L1-2 epidural space and if sensory block reached to T4, then epinephrine 1~5 g/min was intravenously injected with continuous infusion pump. As a result, mean arterial pressure was maintained 50 mmHg, and heart rate, 55~80bpm. In normotensive group, 0.5% bupivacaine 20cc was injected into L4-5 epidural space, and sensory block reached to T8. Therefore blood pressure was maintained within 20% of preoperative baseline. RESULTS: There was apparent difference in blood loss between two groups (hypotensive group: 259 +/- 75 ml, normotensive group: 803 +/- 144*ml) (*:p<0.05). In addition, in the case of hypotensive epidral group, transfusion was not required and CVP, heart rate were not changed postoperatively. Cardiac, renal, and cerebral function were preserved too. CONCLUSIONS: Hypotensive epidural anesthesia with low dose of epinephrine infusion is safely lowering mean arterial pressure to 50 mmHg. This technique is associated with low blood loss, reduction in perioperative transfusion requirements, and has no side effects on CNS, liver, kidney and heart function.

The carpal scaphoid is the commonest of the carpal bones to be fractured, and this injury is the commonest to befall the wrist of working man. There is still some disaggrement as to the optimum treatment and as to how long immobilization should be maintained. The twenty seven cases of the carpal scaphoid were treated at department of orthopaedic surgery, Maryknoll Hospital. They were analyzed in regared to the clinical and radiological aspects. The results were summarized as follows. l. Of 27 cases 24 cases were in the age group 20 to 39, and all cases were male patients. 2. In 17 cases, the fracture was found in right side. 3. In 19 cases (70.4%), the fracture was found on the middle 1/3 of the carpal scaphoid and in 18 cases(66.8%), the fracture line was transverse. 4. The union rate of fracture was 100% in the distal 1/3 fracture, 89.5% in the middle 1/3 fracture and 66.3% in the proximal fracture. The average period of immobilization were 10.3, 14.9 and 15.3 weeks respectively. 5. By Maudsley's assessment, the end result was good in all cases of the distal 1/3 fracture, 84.2% in the middle 1/3 fracture and 66.7% in the proximal 1/3 fracture. 6. Traumatic arthritis developed in 3 cases, avascular ncerosis in 7 cases, nonunion in 4 cases.

BACKGROUND: The purpose of this study was to analyze the endotracheal intubation cases performed in the emergency department. METHODS: We investigated retrospectively 326 cases of endotracheal intubation performed in the emergency department of a tertiary care center from April 1, 1998 to March 31, 1999. We focused on operators, medications used, its success rate and immediate complications, and the relationship between its success rate and medications. RESULTS: Of 326 consecutive intubations, 193 patients(59.2%) were done by emergency medicine residents or attending physician. While 320 patients(98.2%) were successfully intubated, 6 patients could not be intubated and 2 patients underwent tracheostomy. Of 50 cases of intubations(15.3%) attempted with paralyzing agents, 48 cases were done with succinylcholine and 46 cases underwent by emergency physicians. Intubations with neuromuscular paralysis resulted in high success rates at the first attempt. Of 55 immediate adverse events were encountered in 47 patients(desaturation=17, bronchial intubation=15, hypotension=8, bradycardia=4, cardiac arrest=2, others=5). CONCLUSION: At this institution, paralyzing agents were used infrequently, but almost all of them were used by emergency physicians.

In order to survey the reality of anxiety and depression among the Koreans residing in china, a study was conducted between January and March of 1991, on the residents of Yun-Kil city, with subjects of 472 Koreans and 479 Chinese. The evaluation was based on the questionnaires, named Combined self-rating anxiety depression scale (CADS), distributed among the subjects. ANOVA and t-test were applied for data processing. The results were as follows: There was not significant difference in the mean of total scores between the two groups. The scores of Koreans were 29.70±7.03, while those of Chinese were 29.45±9.01. The score of the CADS above 50 (clinically significant level) was seen in 12 (2.54%) Koreans and 21 (4.38%) Chinese. The anxiety-depression scores relating to the items of indigestion and decreased appetite, sleep disturbance, apprehension, decreased libido were relatively high among the Koreans. The items appeared low in scores among the Koreans were faintness, fear, suicidal rumination, hopelessness, paresthesias. The highs among the Chinese were facial flushing, anxiousness, dissatisfaction, suicidal rumination. The items appeared low among the Chinese were fear, faintness, paresthesias, weight loss, suicidal rumination. In the compatison of evaluation by items between the two groups, the items placing the Koreans significantly higher over the Chinese are indigestion & decreased appetite, sleep disturbance, apprehension, decreased libldo. The Chinese marked significantly higher in facial flushing, anxiousness, dissastisfaction, suicidal rumination. Those in the case of female (p<0.01 respectively), less than twenty years old (p<0.01 respectively), dissatisfied with family relationship (p<0.01 respectively), with past history of psychiatric hospitalization (Koreans p<0.01, Chinese p<0.05), pessimistic toward future, present, past self image (p<0.01 respectively) had significantly higher scores in both groups. In religion, neither group showed significant difference. In religion, neither group showed significant difference. In marital status, the Koreans showed a higher degree of divorce and separation and the Chinese in singleness (p<0.01 respectively). The Korean were higher in illiteracy and the Chinese had more college education (p<0.01 respectively). In place of growth, The Koreans showed not much difference in the areas while more Chinese grew up un large cities (p<0.01). More Koreans lived in the dormitory while the Chinese were engaged more in self-cooking (p<0.01 respectively), In pocket money per mouth, more Koreans were less than 1 dollar while the Chinese were between 7 and 10 dollars (p<0.01 respectively). There were no significant difference between two groups about religion.

The distal one-third fractures of tibia have much difficulty in treatment due to enumerous complications such as skin necrosis, angular deformity and delayed union. As for using Ender nails in distal tibial fractures, the stability of fixation can be strengthened with fanning of the nails in distal fragments and using more than 3 nails and 1cm longer nail. Twenty-two patients having distal tibial fractures, were carried out Ender nailing at Department of Orthopaedic Surgery, Maryknoll Hospital from May 1989 to September 1992. The results were as follows; 1. The distal end of fracture line was situated from 3cm to 9cm above plafond, and the mean duration of radiological bony union was 14.9 weeks except one case of nonunion. 2. Mild angulation developed in two cases and complications such as nonunion, superficial infection and backing out of nail were noted, but it did not affect the results.

In 1974, bipolar hip prosthesis was developed by Giliberty and Bateman to reduce the problems of unipolar prosthesis, including acetabular wear and acetabular protrusion, but the indications for it are still controversial. From July, 1988, to February, 1991, at Pusan maryknoll hospital, 37 hips in 33 patients of femoral neck fracture (25 hips) and avascular necrosis (12 hips) with relatively normal acetabular articular cartilage were treated with bipolar hip prosthetic replacement. The thirty-seven cases were reviewed for more than 3 years(range, 3 years to 4 years 8 months: average, 3 years 10 months), and assessed in terms of acetabular migration and function. The authors compared the datas of the femoral neck fracture with those of the avascular necrosis of femoral head. There was no statistical difference between two groups in function. But the acetabular migration of bipolar hip prosthesis used in femoral neck fracture was lesser than that of avascular necrosis of femoral head, and the serial acetabular migration disclosed gradual decrease. The authors concluded that the results of bipolar endoprosthesis used in femoral neck fracture was superior than those of avascular necrosis of femoral head with relatively normal acetabular articular cartilage.
