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 recently had a patient(51 year-old man) who was to undergo resection of pheochromocytoma under general ansthesia. The patient was treated with phenoxybenzamine for 10 days preoperatively. Following induction of anesthesia with intravenous thiopental sodium, endotracheal intubation was performed with vecuronium and anesthesia was maintained with isoflurane. Following intubation, tachycardia controlled by intravenous injection of small dose of propranolol. The course of anesthesia was rather stormy reflected by hypertension, arrhythmia and hypotension. But the patient tolerated long anesthesia and operation relatively well with appropriate use of nitroglycerine, lidocaine, etc. Importance of preoperative preparation, sufficient sedation, smooth induction, complete analgesia, and good muscular relaxation, adequate alveolar ventilation and stable cardiovascular control has been discussed. Blood pressure during manipulation of tumor was 150/100 mmHg without arrhythmia, but gradually was controlled to the range of 120/80 mmHg after intravenous infusion of nitroglycerine at the rate of 0.5-5 pg/kg/min. To our surprise, the blood pressure and pulse and pulse rate was controlled very well with nitroglycerine and isoflurane. After removal of tumor, the blood pressure dropped 100/70 mmHg, so, blood pressure was controlled by LV fluid(Hartmans dextrose, normal saline, plasmanate, low molecular weight dextran), packed red blood cell, whole blood, fresh frozen plasma, vasopressor of small amount was used. There was no marked hypertension, hypotension, tachycardia, arrhythmia during anesthesia. Thus, we anticipate that nitroglyecerine with beta-blocker may be good intraoperative antihypertensive regimen for pheochromocytoma.

BACKGROUND: Clonidine, an 2-adrenergic agonist, shows the analgesic effect and potentiates the analgesic effect of opioid. However, when it is injected with bolus technique, it reveals the short duration of inadequate analgesia and induces hypotension, bradycardia or sedation. We examined the analgesic and side effects of clonidine administered by continuous epidural infusion over 24 hrs, following epidural morphine injection. METHODS: Sixty parturients, scheduled for elective cesarean section under epidural anesthesia were randomly allocated into three groups. They received an infusion of saline alone (group 1, n= 20), clonidine 20 g/hr (group 2, n= 20), or 40 g/hr (group 3, n= 20) respectively, following epidural morphine 3 mg injection at the end of operation. The total doses and number of request for supplemental analgesic, blood pressure, heart rate, and degree of sedation were measured during 24 hrs. RESULTS: There were significant differences in pain relief between clonidine groups and group 1. The total doses and number of patient's request for supplemental analgesic in clonidine groups, compared to group 1 were significantly decreased (p<0.05), but no significant differences between the two clonidine groups. The diastolic pressure of group 3 was significantly lower than that of group 1 over 24 hrs, and that of group 2 at 18 hr, 24 hr (p<0.05). However, there was no severe hypotension, bradycardia or sedation in the three groups. CONCLUSION: Clonidine administered by continuous epidural infusion over 24 hrs enhances the analgesic effect of epidural morphine, and the infusion of clonidine with 20 g/hr rather than 40 g/hr shows minimal changes of blood pressure. Therefore, administration of epidural clonidine (20 g/hr) following epidural morphine may be considered as a regimen for pain management after cesarean section.
