Postoperative stroke is uncommon even in elderly patients, who have a higher incidence of all types of postoperative complications. The mechanism of postoperative stroke is not certain, but can be explained by intravascular clottings originated from thrombus or embolus or by intracranial hemorrhage. In a 66-year-old male patient with current hypertension medication, who underwent both neck dissection for malignancy metastasis under general anesthesia, the left hemiparesis and delayed emergency were found postoperatively. After transferred to intensive care unit, he got the thrombolytic therapy and then the therapies to decrease the swelling of the brain on the diagnosis of cerebral infarction in the vascular distribution of the middle cerebral artery. A brain MRI definitely showed the midline deviation to the left of the right brain hemisphere due to the progressing edematous changes. As he got worse, the emergency neurosurgical operation was proposed but rejected by his family. He died at postoperative 3 days. In this hypertensive patient. perioperative stroke could be originated from the surgical stimuli on major vessels, which were inevitable in neck dissection during the operation. We report this case of the postoperative stroke, which could be highly possible to be associated with extensive head and neck surgery.
The purposes of this study were : 1) to evaluate validity of a pain rating scale using the level of correlation between the Korean Pain Rating Scale(KPRS), Short -Form KPRS(SKPRS) and the Graphic Rating Scale(GRS). 2) to identify sensitivity of the scale using pain behavior of patients with chronic pain. Of the 2025 patients with chronic pain who visited the orthopedic and neurosurgical out - patients departments of 11 university hospitals in various districts of Korea, 520 subjects were selected through convenient sampling and responded to the questionnaires by mail. The results of the study can be summarized as follows : 1. The mean pain score measured by the KPRS was 444,85 : the mean sensory score was 209.47, the mean affective score, 147.63 and the mean miscellaneus score. 87.75. The mean pain score measured by the GRS was 20.11 : the mean sensory intensity score, 10.54. and the mean distress score, 9.57. 2. The average number of hours of rest during the day was 3.3, the average score of discomfort in carrying out ADL was 99, the average frequency of pain relieving practices was 3.0, the average number of pain sites was 3.6. 3. The most sensitive scale to differentiate each group was the GRS, the KPRS and SKPRS were less sensitive than the GRS. 4. The intercorrelation between the KPRS total score and the GRS score(.500) as well as that of the SKPRS score were highly correlated(.652), but intercorrelation between the SKPRS score and the GRS score(.172) was not high. Based on the above results, it was found that the SKPRS must be studied further to obtain validity.
Head Injuries due to traffic accidents are now the leading cause of death and long term disability in males between 30-50 years. Many patients with head injuries experience mild dysfunction of cognition without major neurosurgical problems, and this may interfere with successful rehabilitation. However, not many studies have been done to investigate the cognitive functioning following mild head injuries. The purpose of this study was to obtain injured patient's dermographic data including medical, neuropsychological and social data, and to investigate the cause of injury and alcohol use at the time of injury. This study focused on the recovery of cognitive function in patients with head injuries and used the Mini Mental State Examination(MMSE) score and its correlation with dermographic and social data. Data on 77 patients with minor head injuries who were admitted to the department of Neurosurgery in 3 and I hospital in Dae Jun from September 1991 to February 1992 were analyzed. The findings of this study are as follows ; 1) Out of the 77 cases reviewed in this study, 62 were male, 15 were female. 2) A higher incidence of injury was observed between 7:00 PM and 12:00 PM. 3) The most common cause of head injury in traffic accidents was pedestrian accidents, and the next most frequent cause was motorcycle accidents. 4) Thirteen of the 77 cases in this study were under the influence of alcohol at the time of injury, and they were all male. 5) The MMSE scores one month after injury and at discharge were significantly lower in patients with head injuries that included skull fractures than in patients without skull fractures, suggesting lower cognitive function in patients with skull fractures. 6) The level of consciousness at admission and three days after admission measured by the GCS for drivers under the influence of alcohol was lower than for sober drivers. The MMSE score was also lower for drunken drivers. 7) The MMSE score one month after the injury had a reciprocal relationship with the age of the patient. 8) The MMSE score one month after the injury and at discharge were highly correlated with the duration of unconsciousness. 9) The MMSE score one month after injury and at discharge were highly correlated with the GCS scores at admission, three days after admission, and one week after admission.
The purpose of this study was to identify effective methods to minimize increases in intracranial pressure(IICP ) during endotracheal suction by means of comparing two methods of hyperventilation and oxygen supply before and after endotracheal suction. In order to evaluate the effects of these two methods, the ICP during suctioning and the sustained time of IICP were measured. For hyperventilation, ambu-bagging was done 10 times for 30 seconds with a tidal volume of 800-900m1. For oxygen supply, 100 percent oxygen was supplied for 2 minutes before and after suction. The subjects for this study were 12 neurosurgical patients who had had a subarachnoid bolt inserted for ICP monitoring and they were all on mechanical ventilatory support in a surgical intensive care unit of Seoul National University Hospital from July 1, 1991 to March 31, 1992. In each patient hyperventilation was performed five times and oxygen supply was given five times and intracranial pressures were measured immediately before and every 30 seconds for 15 minutes after suction. For case assignments counterbalancing and repeated measure designs were combined. And so the total number of experiments were sixty for each group. The effects of hyperventilation and oxygen supply on the IICP and the sustained time of IICP after suction were analyzed by t-test. The results of study were as follows 1. There was a significant difference between the two groups in the increased ICP during suction (t=2.49, p=.014). 2. The sustained time of IICP after suctioning in the oxygen supply group was shorter than that in the hyperventilation group(t=2.35, p=.020) In summary, the Increase in the ICP during suction was lower and the time for the ICP to return to the presuction level was shorter in the oxygen supply group as compared to the hyperventilation group. Therefore, oxygen supply can be re commended before and after endotracheal suction.
This study was undertaken to assess the lateral ventricle, which was some portion of brain and related to congenital anomalies, from 1, 2, 4, and 8 months of age in healthy micropigs. They were induced general anesthesia and performed magnetic resonance imaging (MRI) with a 0.3 Tesla magnet. Each age group was evaluated by three subjects such as lateral ventricular volume, ventricular volume ratio and asymmetry. T1 weighted transverse images were acquired for calculation of lateral ventricular and corresponding brain parenchyma areas. The ratio of bilateral ventricle areas used to analyze the asymmetry. The mean ventricular volumes of each month were $676.74{\pm}25.58mm^3$ (1 month-old), $630.64{\pm}143.84mm^3$ (2 month-old), $992.12{\pm}106.03mm^3$ (4 month-old) and $1172.62{\pm}237.57mm^3$ (8 month-old), respectively. The ventricular volume ratio was the smallest at 2 month-old and re-increased from that age. The ratio was significantly different between 2 month-old and other age groups (p < 0.05). The value of bilateral area ratio showed within 1.5 in all experimental animals. Consequently the lateral ventricle showed a positive correlation with aging and symmetric shapes in both sides. The developmental pattern of the lateral ventricle provides basic data in micropigs as an experimental animal model for physiological and neurosurgical approach.
Purpose : This study aimed to compare peripheral pulse oxygen saturation (SpO2) values, measured at different monitoring sites, and arterial oxygen saturation (SaO2) of neurocritical patients. Methods : The study included 110 patients admitted to the neurosurgical intensive care unit of a university hospital. The patients' SpO2 values were measured in their index fingers, both second toes, both earlobes, and foreheads, using the patient monitoring system. These values were compared with the standard value of SaO2 measured using a blood gas analyzer. Data were analyzed using descriptive values, Pearson's correlation coefficients, Lin's concordance correlation coefficients (CCC), and Bland-Altman plots. Result : Regardless of the measuring site, SpO2 was correlated with the paired measurements of SaO2 (r=.40~.60, p<.001, CCC range=.40~.58). No significant bias in paired measurements of SpO2 and SaO2 was observed at all sites (-0.06~0.19%, p>.05). SpO2 values at the left finger and right earlobe had the narrowest range, with a 95% limits of agreement (LOA) (left finger -3.04~2.93% and right earlobe -3.18~2.79%). SpO2 at the index finger, on the side without an arterial catheter, had a narrower range of 95% LOA than that of the opposing finger (-3.00~2.97% vs. -3.73~3.26%). Conclusion : SpO2 at the finger without an arterial catheter had the highest level of precision. This study suggests using the index finger, on the side without an arterial catheter, for pulse oximetry in neurocritical patients.

Purpose : The purpose of this study was to systematically review the instruments utilized to assess physical impairment in post-intensive care syndrome (PICS) of intensive care unit (ICU) survivors. Method : Online databases searched were MEDLINE, Cochrane, CINAHL, and Embase. Studies that met the following criteria were included: 1) the study population exclusively had experience with ICU admission; 2) the study assessed pulmonary, neuromuscular, and physical functions; and 3) the study was published in English language journals after 2007. Results : A total of 56 instruments (2 pulmonary, 25 neuromuscular, 29 physical function) from 94 studies were reviewed. They were classified into self-report, observation, and measurement according to the type of assessment. No instrument measured all 3 areas of physical impairment. Five instruments were originally developed for the ICU patients. The most frequently applied instruments were the Medical Research Council and the 36-item Short Form Survey (physical component summary), which were used in 23 studies each. Only 13.8% of reviewed studies reported the reliability or validity of the instruments. Conclusion : Our results suggest that the appropriateness of instruments assessing physical impairment in PICS cannot be guaranteed. Despite the multidimensional concept of physical disabilities, most studies measured only one area, and studies that reported psychometric properties were limited. Accordingly, we propose to develop a unique and multifaceted instrument for ICU survivors.
This study attempted to identify important problems of the factors related to the indwelling catheter with closed drainage and to enhance recognization of Urinary Tract Infection management to protect patients with indwelling catheter from UTI. We selected the 58 patients with indwelling catheter with closed drainage from md-surg. intensive care units, and general neurological and neurosurgical ward, in one hospital in Pusan, Korea from May 30 to October 15, 1993. Patients were examined by urinary analysis before inserting catheter and then by urine cultures three times. The obtained data was analized using an SPSS /PC$^{+}$ The statistical analyses employed here was the frequency, percentage and x$^2$-tests. 1. Analyses for Indwelling Catheter induced UTI and infection rates were found to be presented in patients related to the factors of being on antibiotic drugs (x$^2$=14.105, p=.000) and the duration of the indwelling catheter(x$^2$=58.0, p=.000), both of which were found to affect the UTI. 2. UTI rates according to the duration of the in-dwelling catheter were high 8.6% for the 2nd day, 27.6 for the 4th day, and 36.2% for the 7th day, and as the duration for the indwelling catheter was longer, UTI rates were higher. 3. The UTI rates according to the duration of the indwelling catheter related re factors, on the 7th day, were high-52.0% for women, 37.0% for more than 50 years in ages, 30.0% for patients under sur-gery, 33.3% for altered mental states outsides the alert, 76.7% for patients not given antibiotic drugs, 36.4% for less than 3500cc of fluids intakes, it was found that these affected to increase the UTI. 4. Causative organisms of UTI were found ; E.Coli appears the most than all other isolated organisms in women and Klebsiella and Pseudomonas in men. For antibiotic susceptibility of causative organisms, all causative organisms were found to be susceptible to Sul -cefoperazone, Trim-prim, and unasyn and Pseudomonas mostly net susceptible.e.

Objective: The purpose of this study was to evaluate factors associated with inpatient admission following 2-level cervical disc arthroplasty (CDA). A secondary aim was to compare outcomes between those treated on an inpatient versus outpatient basis. Methods: Using data from the American College of Surgeons National Surgical Quality Improvement Program database, multivariate logistic regression analysis was used to assess the independent effect of each variable on inpatient or outpatient selection for surgery. Statistical significance was defined by p-values <0.05. The factors considered were age, sex, body mass index (BMI), smoking status, American Society of Anesthesiologists physical status classification, and comorbidities including hypertension, diabetes, history of dyspnea or chronic obstructive pulmonary disease, previous cardiac intervention or surgery, steroid usage, and history of bleeding. In addition, whether the operation was performed by an orthopedic or neurosurgical specialist was analyzed. Results: The number of 2-level CDA procedures increased from 6 cases reported in 2014 to 142 in 2016, although a statistically significant increase in the number of outpatient cases performed was not seen (p=0.2). The factors found to be significantly associated with inpatient status following surgery were BMI (p=0.019) and diabetes mellitus requiring insulin (p=0.043). There were no significant differences in complication and readmission rates between the inpatient and outpatient groups. Conclusion: Patients undergoing inpatient 2-level CDA had significantly higher rates of obesity and diabetes requiring insulin than did patients undergoing the same procedure in the outpatient setting. With no difference in complication or readmission rates, 2-level CDA may be considered safe in the outpatient setting in appropriately selected patients.
A retrospective study has been made of 170,026 cases of motor vehicle accidents which had been reported to the National Police Headquarters of Republic of Korea, 1983. Also a study has been made of 264 cases of road traffic casualties who were treated at the Eul-ji General Hospital from Jan. 1, 1983 to Dec. 31, 1983. This study was conducted to find out the nature and pattern of the traffic accidents from the clinical and epidemiological view points. In additions, the modes of injury from the road accidents were persued which might help to reduce the traffic accident rate. The results of the study were summarized as follows; 1. In this study, the highest incidence was in the age group between $21{\sim}30$ years (21.29%). And the age group of highest death rate was under 10 years (7.28%). 2. In the comparison of sexual differences, male was dominated in accidents number and death rate. (Casualty rate; 61.66%). 3. In the comparison of each hour differences, the accident was mostly occured during afternoon from 16:00 to 18:00(12.23%). 4. The most common day of week was Sunday (14.74%). 5. The most common season of year was Autumn (27.92%). 6. In the comparison of occupational differences, the high incidences were showed in labor men (31.06%) and business men (12.12%). 7. In the comparison of accidental vehicles, the most common vehicle were cars and the next were trucks and buses. 8. The most common mechanism of accidents was collision (57.41%). 9. In the comparison of clinical differences, orthopaedic and neurosurgical injuries were most common types of the hospitalized casualties. 10. In the comparison of anatomical fracture sites, the most common site was tibia (15.81%) and the next site was femur (12.56%).
