Anestheiologists face the difficulty of mainatining patent airway in performing anesthesia for surgery around vocal cords. Because the simplicity of the above operation, the surgeons and patients tend to avoid the preparatory tracheostomy which is a safe way of maintaining anesthesia. The difficulties and problems occurring during anesthesia without performing tracheotomy were considered. The problems were; 1) Operating field interfering the anesthetic procedures. 2) Possibility of aspiration of blood during operation. 3) Apnea time of surgery limiting to 5 minutes or less. 4) Repeated intubation for anesthesic procedure. Apneic insufflation method was modified by spontaneous respiration. The tehnic was; the endotrachel tube was removed after induction of general anesthesia when patients spontaneous respiration regained Then suction catheter, 12 fr. size, was inserted to above the carina of trachea. Next, for ventilation, oxygen with high flow rate (9~10 L/Min) was insufflated in trachea through the catheter. This insufflation of high flow oxygen brought continuous positive pressure in trachea, also it acted effectively as PEEP (positive end expiratory pressure) effect .and provided protective mechanism from the aspiration. The addition of potent anesthetics such as halothane and ether insufflating oxygen allowed the control of depth of anestheia effectively. With this insufflation technic, two cases of excision of singers nodule were performed uneventfully.

STUDY DESIGN: A prospective clinical study with radiologic assessment was conducted. OBJECTIVES: To analyze the height changes of the intervertebral disc and neural foramen and width changes of the neural foramen after anterior lumbar interbody fusion and posterior fixation in the lumbar spine. SUMMARY OF LITERATURE REVIEW : Anterior lumbar interbody fusion distracts the height of the intervertebral disc and neural foramen and the width of the neural foramen. MATERIALS AND METHODS: Minimal anterior lumbar interbody fusion and posterior fixation were performed in 20 cases from January 1999 to January 2001. The measuring factors were the height of the anterior and posterior discs, and the height and width of the neural foramen, measured with a caliper in 1mm reconstructive, computed tomography, sagittal images before and 6 months after anterior lumbar interbody fusion. The factors were independently measured by three different persons. RESULTS: The height of the anterior and posterior discs was increased by mean 32.2% and 40.5%, respectively. The height of the right and left neural foramen was increased by mean 15.7% and 18.3%, respectively. The width of the superior, middle and inferior neural foramen was increased by mean 20.6%, 30.3% and 38.6%, respectively. There were significant increases in all measuring factors after minimal anterior lumbar interbody fusion. CONCLUSIONS: Minimal anterior lumbar interbody fusion significantly increased the height of the anterior and posterior intervertebral discs, and the height and width of the neural foramen, and produced neural decompression.

Spinal fusion is a common procedure that provides spinal stability by connecting vertebral segments using a bone graft. Because the spinal alignment is fixed permanently after spinal fusion, a mal-aligned fusion can produce iatrogenic spinal deformity and imbalance with significant disability.Current Concepts: Failure to restore adequate segmental lordosis in lumbar spinal fusion is a common cause of iatrogenic spine deformity. Local and regional spinal deformities can affect the global alignment; accordingly, spinal imbalance can occur when the compensation mechanisms fail. Diagnosis and surgical planning should be made on a thorough analysis of global and spinopelvic parameters on the standing whole-spine radiographs. Surgical treatment includes neural decompression, spinal fusion, and deformity correction. Spinal osteotomy provides a favorable surgical outcome, although the complication rate is high.Discussion and Conclusion: Iatrogenic spine deformity is increasing due to the increased occurrence of spinal fusion surgery. To prevent iatrogenic spine deformity, the index fusion surgery should be performed based on a comprehensive analysis of spinopelvic alignment and balance.

Purpose: The purposes of this study were to compare the magnitude and phase between the RR interval and QT interval variability in the frequency domain. METHODS: Twenty four, 12-13 year old healthy males were randomly selected. At resting state and for 5 minutes, ECGs were obtained, and they were digitized to 1000Hz. After measurement of RR interval, QT interval variability was measured using template matching strategy. After normalization of the RR and QT interval time series, power spectral and cross spectral analysis were performed. From each of the time series, low- (0.04-0.15 hertz) and high- (0.15-0.4 hertz) frequency power were measured. From the phase spectrum, the phases and time lags between the two time series at each of the two frequency range were calculated. RESULTS: The average of RR interval and QT interval was 616.0+/-71.0, 364.0+/-47.0 msec, respectively. Their normalized low- and high- frequency power was 4.4+/-7.9 NU(normalized unit), 0.1+/-0.1 NU(p<0.005), and 11.0+/-30.0 NU, 0.3+/-0.3(NU, p<0.005), respectively. The phase differences and resulting time lags between the two interval were -0.5+/-0.4 pi radian(-0.9 seconds) and -0.2+/-0.3 pi radian(-0.4 seconds) in the low- and high-frequency range, respectively. CONCLUSION: During resting state, when compared to RR interval, QT interval oscillates in significantly lower amplitude in both low- and high- frequency ranges. However, the oscillations precede those of the RR interval 0.9 seconds and 0.4 seconds, respectively.

We report on a case of successful management of a patient with abdominal aortic rupture requiring massive blood transfusion during the peri-operative period. The patient had fully recovered 19 days after the operation, through intra-operative cardiac arrest and massive transfusion. We analyze a process of blood transfusion and related complications resulting from massive transfusion in order to establish a treatment for peri-operative patients with hypovolemic shock.

From March 1982 to June 1985, Serum FSH, LH and prolactin were taken in 85 normal males, 37 benign prostatic hyperplasia and 7 prostatic carcinomas, Radioimmunoassay resulted in the following findings. 1. Serum FSH is seen to increase steadily with age in both normal subjects and patients with BPH. No difference was found in the value of the FSH between the 2 group. 2. Serum LH is seen to increase sharply after 70 years of age but level of LH in the benign prostatic hyperplasia do not reflect this age related increment. 3. Serum prolactin is seen to remain relatively unchanged in the normal male through adult life. No difference was observed between patients with BPH and normal age-matched control.

The etiology of spondylolisthesis, which determines the pathoanatomy and natural course, includes the abnormal development of lumbosacrum and various acquired conditions. Many patients with symptomatic degenerative and isthmic spondylolisthesis respond to non-surgical treatments, such as modification of their daily activity, medication, physical therapy and nerve block.

STUDY DESIGN: A retrospective radiologic study. OBJECTIVES: We wanted to compare the compression ratio and kyphosis of thoracolumbar and lumbar fractures according to the radiologic measuring methods and we wanted to analyze their relationship with the stability of fracture. SUMMARY OF THE LITERATURE REVIEW: There are several methods for measuring the compression ratio and kyphotic angle in thoracolumbar fractures, but no definitive measurements and no different values according to the stability have been established. MATERIALS AND METHODS: From July 2002 to August 2008, the plain films, CT, MRI and medical records of thoracolumbar and lumbar fracture were reviewed. The compression ratio and kyphotic angle were calculated by several different formulas with using the lateral view of the plain X-ray film, the sagittal reconstruction image of CT and the sagittal image of MRI and the results were compared. Each subject was classified according to both McAfee's classification and the TLISS classification. RESULTS: Two hundred forty eight vertebral bodies of 205 thoracolumbar fracture patients were analyzed. The compression ratio according to formula 1, which was calculated as 1-anterior vertebral height/posterior vertebral height, was significantly correlated with Cobb's angle and the local kyphotic angle. There was no significant difference between the Cobb's angle calculated using the lateral X-ray and that using the sagittal view of CT; however, it was significantly less using the sagittal MRI view. The unstable fractures according to McAfee's classification showed a significantly higher compression ratio and kyphotic angle compared to those of the stable fractures. CONCLUSIONS: The compression ratio formula 1 was most significantly correlated with the kyphotic deformity. The unstable fractures showed a mean compression ratio higher than 30%, a mean Cobb's angle of 15degrees and local kyphotic angle of 18degrees. The sagittally reconstructed CT was a useful measuring method for the evaluation of kyphotic deformity, and it was more accurate than that of the plain film.
