The Effects of Continuation-Maintenance Electroconvulsive Therapy on Reducing Hospital Re-Admissions in Patients with Treatment-Resistant Schizophrenia

OBJECTIVE: Continuation-maintenance electroconvulsive therapy (C/M-ECT) is used to prevent relapse or recurrence in patients with severe mental illnesses. We aimed to investigate the effect of C/M-ECT on reducing hospital re-admissions in patients with treatment-resistant schizophrenia. METHODS: We applied a mirror-image design by retrospectively examining re-hospitalization rates of 18 patients with schizophrenia spectrum disorders. We compared the numbers of psychiatric admissions during the actual period over which C/M-ECT was administered with the same period prior to the beginning of C/M-ECT. RESULTS: The number of psychiatric admissions was reduced significantly during C/M-ECT (0.33±0.77) compared with that of the same period prior to C/M-ECT (2.67±1.33) (Wilcoxon signed rank Z=−3.663; p < 0.001). CONCLUSION: This finding shows that C/M-ECT augmentation could successfully reduce the re-hospitalization rates in patients with treatment-resistant schizophrenia.

Executive Dysfunction in Obsessive-Compulsive Disorder and Anterior Cingulate-Based Resting State Functional Connectivity

OBJECTIVE: Executive dysfunction might be an important determinant for response to pharmacotherapy in obsessive-compulsive disorder (OCD), and could be sustained independently of symptom relief. The anterior cingulate cortex (ACC) has been indicated as a potential neural correlate of executive functioning in OCD. The present study examined the brain-executive function relationships in OCD from the ACC-based resting state functional connectivity networks (rs-FCNs), which reflect information processing mechanisms during task performance. METHODS: For a total of 58 subjects [OCD, n=24; healthy controls (HCs), n=34], four subdomains of executive functioning were measured using the Rey-Osterrieth Complex Figure Test (RCFT), the Stroop Color-Word Test (SCWT), the Wisconsin Card Sorting Test (WCST), and the Trail Making Test part B (TMT-B). To probe for differential patterns of the brain-cognition relationship in OCD compared to HC, the ACC-centered rs-FCN were calculated using five seed regions systemically placed throughout the ACC. RESULTS: Significant differences between the OCD group and the HCs with respect to the WCST perseverative errors, SCWT interference scores, and TMT-B reaction times (p<0.05) were observed. Moreover, significant interactions between diagnosis×dorsal ACC [S3]-based rs-FCN strength in the right dorsolateral prefrontal cortex for RCFT organization summary scores as well as between diagnosis×perigenual ACC [S7]-based rs-FCN strength in the left frontal eye field for SCWT color-word interference scores were unveiled. CONCLUSION: These network-based neural foundations for executive dysfunction in OCD could become a potential target of future treatment, which could improve global domains of functioning broader than symptomatic relief.

Association between Quality of Life and Symptom Severity in Obsessive-Compulsive Disorder Patients Using EQ-5D

OBJECTIVES: Obsessive-compulsive disorder (OCD) is a disabling psychiatric disorder, and more attention is recently paid on the quality of life (QoL) in OCD patients. The Euro-QoL-5D (EQ-5D) is a widely used self-report to calculate a single score which represents ‘health utilities’. The aim of this study was to assess the health-related QoL for patients with OCD using the EQ-5D and to examine the relationship between health-related QoL and symptom severity. METHODS: Seventy-three patients with a Diagnostic and Statistical Manual of Mental Disorders (DSM-5) diagnosis of OCD were recruited from the outpatient clinic in Seoul National University Hospital. Symptom severity was assessed using the Yale-Brown Obsessive-Compulsive Scale (YBOCS), and QoL was assessed with the EQ-5D-5L questionnaire. Using Korean valuation study, a single score of QoL was calculated. RESULTS: Most of the OCD patients were relatively young (< 45 years) with the mean YBOCS total score of 19.33. The mean EQ-5D score was 0.71 and significantly correlated with symptom severity (r = -0.483, p < 0.001). 25% of the EQ-5D score was predicted by the YBOCS total score (b = -0.011, p < 0.001) by regression analysis. CONCLUSIONS: OCD patients suffer from lower health-related QoL and QoL significantly decreased as symptom severity increased. The results of the EQ-5D would enable further studies on QoL comparison across medical disease and mental disorders.

Neurocognitive Dysfunction in Patients with Obsessive-Compulsive Disorder in Association of Duration of Untreated Illness : A Preliminary Study

OBJECTIVES: Obsessive-compulsive disorder (OCD) is a chronic and disabling psychiatric disorder. The duration of untreated illness (DUI) has been suggested as one of the predictors of clinical course and outcome in various psychiatric disorders. There is increasing evidence that cognitive dysfunction is associated with the prognosis of OCD. The aim of this study was to investigate the influence of DUI on the neurocognitive functions in patients with OCD. METHODS: Sixty-two patients with a DSM-IV diagnosis of OCD from the outpatient clinic were included in this study. We defined the short DUI if the DUI was 2-year or less and the long DUI if it was longer than 2-year. Neurocognitive functions were assessed by visuospatial memory function test and 4 subsets of K-WAIS such as vocabulary, arithmetic, block design and picture arrangement. Differences in neurocognitive functions as well as clinical variables between OCD patients with short DUI and those with long DUI were investigated. Correlation analyses were also performed to determine the correlation between DUI and neurocognitive functions. RESULTS: Compared with the short DUI group, the long DUI group performed worse in the block design test, which measures executive function. The long DUI group also had a higher level of compulsive symptom severity than the short DUI group. However, the DUI was not correlated with neurocognitive functions. CONCLUSIONS: Findings in this preliminary study suggest that the long DUI in patients with OCD is associated with more severe executive dysfunction. Studies with larger samples and longitudinal design are needed to further confirm the prognostic role of the DUI in OCD.

Reconsidering Clinical Staging Model: A Case of Genetic High Risk for Schizophrenia

The clinical staging model is considered a useful and practical method not only in dealing with the early stage of psychosis overcoming the debate about diagnostic boundaries but also in emerging mood disorder. However, its one limitation is that it cannot discriminate the heterogeneity of individuals at clinical high risk for psychosis, but lumps them all together. Even a healthy offspring of schizophrenia can eventually show clinical symptoms and progress to schizophrenia under the influence of genetic vulnerability and environmental stress even after the peak age of onset of schizophrenia. Therefore, individuals with genetic liability of schizophrenia may require a more intensive intervention than recommended by the staging model based on current clinical status.

Internet-Based Cognitive Behavioral Therapy for Obsessive-Compulsive Disorder in Korea

OBJECTIVE: Cognitive behavioral therapy (CBT) is regarded as one of the most effective intervention for obsessive-compulsive disorder (OCD). However, many patients remain untreated or inadequately treated due to time or geographical constraints. The purpose of this study was to develop an internet-based CBT (ICBT) for OCD, and to examine its efficacy in the Korean clinical setting. METHODS: The ICBT program ('COT') was developed from the same OCD manual in the standard CBT intervention. Twenty-seven participants of the total 42 patients completed all training sessions of the ICBT and the remainder (n=15) were classified as non-completers. Self-report measures of OCD, depression, anxiety, and work/social functioning, in addition to a neurocognitive test battery, were administered by face-to-face before and after treatment. RESULTS: The participants showed significant improvements in OCD and depressive symptoms, and in work/social functioning after ICBT completion. The presence of combined medication had no significant impact on treatment effect. The non-completers displayed more severe depressive and anxiety symptoms, and ICBT responders were younger and performed better in the Wisconsin Card Sorting Test. CONCLUSION: ICBT was found to be as effective for patients with moderate OC symptoms and little treatment experience. Considering the high accessibility and convenience of ICBT, it could be a helpful first treatment step for OCD patients when face-to-face treatment is unavailable. In the future a randomized controlled study will be necessary for verification and generalization of these results.

Risk Factors for Suicidal Ideation among Patients with Complex Regional Pain Syndrome

OBJECTIVE: Chronic pain frequently coexists with psychiatric symptoms in patients diagnosed with complex regional pain syndrome (CRPS). Previous studies have shown a relationship between CRPS and the risk of suicide. The purpose of this study was to assess risk factors for suicidal ideation in patients with CRPS. METHODS: Based on criteria established by the International Association for the Study of Pain, 39 patients diagnosed with CRPS Type 1 or Type 2 were enrolled in this study. Suicidal ideation was assessed using item 3 of the Hamilton Depression Rating Scale (HAMD), and symptoms of pain were evaluated using the short form of the McGill Pain Questionnaire (SF-MPQ). Psychiatric symptoms were assessed in using the Structured Clinical Interview for DSM-IV Disorders (SCID-I, SCID-II), the HAMD, the Hamilton Anxiety Rating Scale (HAMA), the Global Assessment of Functioning Scale (GAF), and the Pittsburgh Sleep Quality Index (PSQI). RESULTS: Twenty-nine patients (74.4%) were at high risk and 10 (25.6%) were at low risk for suicidal ideation. Risk factors significantly associated with suicidal ideation included depression (p=0.002), severity of pain (p=0.024), and low scores on the GAF (p=0.027). No significant correlations were found between suicidal ideation and anxiety or quality of sleep. CONCLUSION: Significant risk factors for suicidal ideation in patients with CRPS include severity of pain, depressive symptoms, and decreased functioning. These results suggest that psychiatric evaluation and intervention should be included in the treatment of CRPS.

Factors Associated with the Compliance of Cognitive Behavioral Therapy for Obsessive Compulsive Disorder / 신경정신의학

OBJECTIVES: Non-completion rate of cognitive behavioral therapy (CBT) for Obsessive Compulsive Disorder (OCD) was reported to be higher than expected and it could interfere with the effectiveness of treatment. The aim of this study was to investigate predictors of treatment non-completion and to compare the effectiveness of CBT for OCD between completers and non-completers. METHODS: We studied 107 patients with a principal diagnosis of OCD who initiated a 13-week CBT for OCD from June 2004 to June 2011. Demographic and clinical characteristics, psychiatric co-morbidity, and medication of 20 participants who did not complete therapy were compared with those of treatment completers (n=87). Clinical Global Impression scores were also compared between the two groups in order to evaluate the effect of CBT for OCD at the 13th week. RESULTS: The results showed a difference in marital status between treatment completers and non-completers : more non-completers were not married (p=0.04). Patients with aggressive obsessions at baseline showed a trend (p=0.06) toward lower treatment completion than those with only non-aggressive obsession. In addition, the non-completer group showed a trend of not being medicated (p=0.08). No other differences were observed between completers and non-completers. The 13th week Clinical Global Impression-Improvement scores were significantly different ; completers (2.5+/-0.8) and non-completers (3.2+/-0.8) (p<0.001). CONCLUSION: In this study, we confirmed that CBT could affect symptom improvement of OCD and treatment non-completion interfered with effectiveness of CBT. However, in the current state of our knowledge, no factor is clinically applicable as a predictor of treatment non-completion. Therefore, these results suggest that clinicians should monitor compliance during CBT for OCD patients.

The Impact of Personality Traits on Ratings of Obsessive-Compulsive Symptoms

OBJECTIVE: The goal of this study was to evaluate consistencies and discrepancies between clinician-administered and self-report versions of the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) and to examine relationships between these scales and personality traits. METHODS: A total of 106 patients with obsessive-compulsive disorder (OCD) participated in this study. All participants were assessed with both clinician-administered and self-report versions of the Y-BOCS. The Structured Clinical Interview for DSM-IV Axis II Disorders Personality Questionnaire (SCID-II-PQ) was used to evaluate relationships between personality traits and scores on the Y-BOCS. RESULTS: Scores on the clinician-administered Y-BOCS and its obsession subscale were significantly higher than were those on the self-report version. However, we found no significant differences in compulsion subscale scores. We also found that the discrepancies in the scores on the two versions of the Y-BOCS and its compulsion subscale were significantly positively correlated with scores for narcissistic personality traits on the SCID-II-PQ. Additionally, narcissistic personality traits had a significant effect on the discrepancy in the scores on the two versions of the Y-BOCS and its compulsion subscale in the multiple linear regression analysis. CONCLUSION: This is the first study to elucidate relationships between personality traits and discrepancies between scores on the two versions of the Y-BOCS. Although clinicians tend to rate obsessive symptoms as being more severe than do patients, clinicians may underestimate the degree to which individuals with narcissistic personality traits suffer more from subjective discomfort due to compulsive symptoms. Therefore, the effect of personality traits on symptom severity should be considered in the treatment of OCD.

Impact of the BDNF Val66Met Polymorphism on Regional Brain Gray Matter Volumes: Relevance to the Stress Response

OBJECTIVE: Genetic imaging is used to investigate the mechanism by which genetic variants influence brain structure. In a previous study, a structural change of the dorsolateral prefrontal cortex was associated with symptom modulation in post-traumatic stress disorder patients. This study examined the effect of a polymorphism in the gene encoding brain-derived neurotrophic factor (BDNF) on regional gray matter (GM) volumes and the correlations between the dorsolateral prefrontal GM volume and the stress level in healthy volunteers. METHODS: Sixty-one volunteers underwent genotyping for the BDNF Val66Met single nucleotide polymorphism (SNP) and completed the Stress Response Inventory (SRI). Magnetic resonance images were also acquired, and the effect of each subject's BDNF genotype and SRI subscore on his or her dorsolateral prefrontal GM volume was evaluated. RESULTS: The Val/Val homozygotes had significantly larger GM volumes in the prefrontal cortex and the precuneus, the uncus, and the superior temporal and occipital cortices than Met carriers. The Met homozygotes demonstrated a higher stress response in depression domain than Val/Val and Val/Met groups. A negative correlation between the middle frontal cortex GM volume and the SRI depression subscore was found. CONCLUSION: These findings indicate an interaction between genes and brain structure, and they suggest that differences in dorsolateral prefrontal GM volume related to the BDNF Val66Met SNP are associated with resilience to stressful life events, particularly in the dimension of emotion.

Association between Mismatch Negativity and Functional Status in Patients with Schizophrenia / 대한정신분열병학회지

OBJECTIVES: It has been constantly reported that mismatch negativity (MMN) is impaired in patients with schizophrenia. However, the mechanism which relates impaired MMN and schizophrenia is not clear yet. The aim of this study is to investigate the association between MMN and clinical variables including functional status in patients with schizophrenia. METHODS: The present study assessed MMN using passive auditory oddball task in 26 patients with schizophrenia and 48 healthy controls. Repeated measures Analysis of Variance with age as a covariate was carried out for comparing peak amplitude and latency of MMN at 8 central line electrodes (FPz, Fz, FCz, Cz, CPz, Pz, POz, Oz) across groups. Pearson's correlation was performed to reveal the relationship between MMN and clinical variables including neurocognitive test results and the Global Assessment of Functioning score. RESULTS: MMN amplitude was significantly reduced in patients with schizophrenia compared with healthy controls. Pearson's correlation showed that subsets of short form of Korean Wechsler Adult Intelligence Scale scores and GAF scores were associated with MMN amplitude in patients with schizophrenia. CONCLUSION: These findings suggest that MMN amplitude is associated with current functional status including cognitive function in patients with schizophrenia.

Multidimensional Comparison of Personality Characteristics in Genetic High Risk for Schizophrenia, First Episode Psychosis and Healthy Controls / 대한정신분열병학회지

OBJECTIVES: Previous studies have suggested that some personality characteristics are associated with the onset, prognosis and social function in schizophrenia patients. However few is known about the personality and affective characteristic of genetic high risk group (GHR) for schizophrenia. This study aimed to investigate the personality and the affective characteristic of GHR group for schizophrenia. METHODS: Participants were 54 healthy controls (HC), 26 subjects with GHR for schizophrenia and 28 subjects with first episode psychosis (FEP). We performed three self-report questionnaires; NEO-Personality Inventory-Revised, State and Anger Expression Inventory and Positive Affect and Negative Affect Schedule. RESULTS: The GHR group showed higher score in agreeableness item than the HC (p=0.028). In extraversion item, the FEP group showed significantly lower scores than the HC (p=0.001). The GHR group showed lower scores in neuroticism item compared with FEP group in trend level. The FEP group showed higher trait-anger, lower positive affect and higher negative affect compared with the others. CONCLUSION: The GHR group seem to share certain vulnerable personality and affective characteristics for schizophrenia with the FEP group. On the other hands, the GHR group appeared to be more agreeable than the other groups, which might act as the compensation for other impaired functions.

Pilot Study on Resting-State Functional Connectivity under the Effects of Familial Loading in People at Ultra-High Risk for Psychosis / 대한정신분열병학회지

OBJECTIVES: People at ultra-high risk for psychosis have heterogenous character and different long-term outcomes. We divided ultra-high risk subjects into two subgroups by presence of familial history and tried to find different pattern of functional connectivity of the default mode network (DMN) between the two groups in order to examine the effects familial loading. METHODS: Eleven subjects at clinical-high risk (CHR) group with familial history of psychiatric illness and nineteen subjects of CHR group without familial history were recruited. All the subjects were scanned using resting-state functional magnetic resonance imaging. A posterior cingulate cortex was the seed region of the analysis, and the DMN of the both high risk group were analyzed with voxel-wise two sample T test. RESULTS: The CHR group with familial history showed greater functional connectivity in the precuneus area in contrast with the other high risk subjects (peak-level t=5.49, p<0.001). There were no significant differences in total score on the Positive and Negative Syndrome Scale and Scales of Psychosis-risk Syndrome between the two groups. CONCLUSION: The study suggests that the abnormalities of functional connectivity between precuneus and posterior cingulate area may be associated with the genetic vulnerability of high risk trait.

The Safety and Efficacy of Ziprasidone: Post-Marketing Surveillance Study in Korea / 대한정신약물학회지

OBJECTIVE: The aim of this study was to observe the safety and efficacy of ziprasidone in the usual care setting in patients with schizophrenia or acute manic or mixed episodes associated with bipolar disorder. METHODS: A total of 3,391 patients who were treated with ziprasidone were enrolled from 108 centers in Korea. Differences in the clinical global impression of severity and clinical global impression of improvement (CGI-I) were measured after 8+/-1 weeks administration of ziprasidone. Adverse events were observed in all subjects who were administered ziprasidone at least once. In 330 patients, the change of weight was evaluated. RESULTS: Ziprasidone was effective for most of schizophrenia and acute manic or mixed episodes associated with bipolar disorder patients. CGI-I score was improved in 84.8% of PP subjects. Of the subjects who did not complete the study, sixty-four (1.9%) subjects discontinued treatment due to adverse events. The most common adverse events were akathisia, somnolence, extrapyramidal symptoms and insomnia. In total, 6 serious adverse events were reported in 2 subjects, including psychotic disorder and suicidal attempt. Mean 0.9 kg of weight loss was observed. CONCLUSION: Ziprasidone was effective, safe and generally well tolerated for schizophrenia or acute manic or mixed episodes associated with bipolar disorder patients in Korea.

Predictors of Clinical Response to Escitalopram in Obsessive-Compulsive Disorder / 대한정신약물학회지

OBJECTIVE: In this study, we aimed to investigate the predictors of clinical response to escitalopram (ESC) in obsessive-compulsive disorder (OCD) from the baseline clinical characteristics. In addition, we aimed to search the differences of prescription pattern between responders and non-responders to ESC. METHODS: Two hundred and twenty-three patients who met the DSM-IV criteria for OCD and visited at least once after the initiation of ESC prescription were included in this study. A primary outcome measure was the Clinical Global Impression-Improvement scale (CGI-I), which was scored at the time of retrospective chart review. Responders were defined as those with a CGI-I score of 1 or 2 at the final point of evaluation. Baseline clinical characteristics, prescription patterns, and adverse events were compared between responders and non-responders. We also examined the validity of the prediction model regarding treatment response to ESC. RESULTS: The OCD patients having aggressive obsessions and related compulsions showed significantly decreased response rate to ESC (odd ratio=0.285) in comparison with the OCD patients not having aggressive symptom dimension (p=0.002). The maximum dose of ESC prescription and rate of antipsychotics combination were higher in responders in comparison to the nonresponders. Among the adverse effects, sedation and constipation showed significantly different occurrence rate between responders versus non-responders. CONCLUSION: Aggressive obsessions and related compulsions seem to be associated with poor clinical response to ESC in OCD. Obsessive-compulsive symptom dimension should be considered when choosing a serotonin reuptake inhibitor for OCD.

Screening for the Coexistence of Congenital Muscular Torticollis and Developmental Dysplasia of Hip

OBJECTIVE: To investigate the coexistence rate and related factors of developmental dysplasia of the hip (DDH) and congenital muscular torticollis (CMT), and to determine whether ultrasonography (US) gives good value for screening of DDH in CMT. METHOD: We prospectively examined 121 infants (73 males and 48 females) diagnosed with CMT to determine the incidence of DDH by US. We also assessed the relationship between neck US findings and DDH occurrence, and investigated the clinical features of CMT related to DDH. RESULTS: 18 patients (14.9%) were diagnosed as having DDH by US. However, most DDH was subclinical and spontaneously resolved. Only 2 patients (1.7%) needed to be treated with a harness. The positive predictive value of clinical examinations for DDH was 52.6% and patients treated by harness were all clinically positive. DDH was more common in the left side (13 left, 4 right, 1 both), but 6 out of 18 DDH (33.3%) cases presented on the contralateral side of CMT. Sex difference was not observed. Breech presentation and oligohydramnios were not related to DDH occurrence. Neck US findings did not correlate with DDH occurrence. CONCLUSION: The coexistence rate of CMT and DDH was concluded to be 14.9%. If only DDH cases that required treatment were included, the coexistence rate of these two disorders would be lowered to 1.7%. All of these patients showed positive findings in clinical examination. Therefore, hip US should not be recommended routinely for patients with CMT.

Cauda Equina Syndrome Caused by Spinal Dural Arteriovenous Fistula

Spinal dural arteriovenous fistula (SDAVF) is rare but still the most commonly encountered vascular malformation of the spinal cord. A 31-year-old male developed gait disturbance due to weakness of his lower extremities, voiding difficulty and sexual dysfunction with a progressive course since 3 months. He showed areflexia in both knees and ankles. Electromyographic findings were suggestive of multiple root lesions involving bilateral L2 to S4 roots of moderate degree. Magnetic resonance images showed high signal intensity with an ill-defined margin in T2-weighted images and intensely enhanced by a contrast agent through the lumbosacral spinal cord. Selective spinal angiography confirmed a dural arteriovenous fistula with a nidus at the L2 vertebral level. After selective endovascular embolization, his symptoms drastically improved except sexual dysfunction. We report a rare case of cauda equina syndrome due to spinal arteriovenous fistula with drastic improvement after endovascular embolization.

Effect on the Bone Mineral Density According to Weight-bearing Exercise in Children with Spastic Quadriplegic Cerebral Palsy: A Preliminary Study

OBJECTIVE: To evaluate the effect of weight-bearing exercise on the bone mineral density (BMD) in children with spastic quadriplegic cerebral palsy (CP). METHOD: A heterogeneous group of 18 prepubertal children with CP (age, 8.9+/-2.9 years; GMFCS level, IV and V) participated. Patients underwent a dual-energy X-ray absorptiometry scan of the lumbar spine (L1-L4) and proximal femur, and the Z scores were calculated by using data obtained from the control group who were normal children (age, 8.8+/-2.9 years). We divided the patients into 2 groups: group A standing for 2 hours a day, 5 days a week; group B standing for 30 minutes a day, 1 or 2 days a week. We measured BMD after 1 year and compared it to baseline measurements. RESULTS: BMD was significantly higher on L2-L4 vertebrae, femoral neck and trochanter area after exercise in group A (p0.05). BMD according to static weight-bearing exercise for 1 year were significantly different between groups A and B on the L1, L4 vertebrae, femoral neck and trochanter area (p<0.05). CONCLUSION: This study suggests that weight-bearing exercise may be an important part of a rehabilitation protocol to maintain and improve BMD in children with spastic quadriplegic CP.

Merosin Negative Congenital Muscular Dystrophy Who Was Misdiagnosed Initially as Cerebral Palsy: A case report

Congenital muscular dystrophies (CMDs) are autosomal recessive, heterogenous disorders characterized clinically by neonatal hypotonia, delayed motor milestones, joint contractures, and dystrophic changes in the muscles. The classic forms of CMDs are subclassified into merosin positive and deficient (negative) types. Merosin (laminin alpha chain)-negative CMD is caused by the mutation in the basal lamina of the alpha2 chain gene (LAMA2 gene at 6q22-23). Merosin deficiency could disrupt the attachment of muscle cell to the extracellular matrix and lead to muscle cell necrosis. We report a case of merosin-negative CMD, confirmed by immunohistochemical staining of muscle samples, which is uncommon form in Korea.

Anesthesia or Kidney Transplantation - report of 5 cases / 대한마취과학회지

This is a report of anesthesia for five cases of renal transplantation which was performed between February 1969 and August 1969 at St. Mary's Hospital, Catholic Medical College, Seoul, Korea. General of renal insufficiency of the operated cases were described. Operative technique were unilateral nephrectomy for three cases and bilateral nechprectomy with splenectomy for 2 cases ; Anesthesia was induced with epontol (propanidid) 250mgs i.v. and 4% halothane-oxygen and maintained with 1% halotbane-oxygen which was supplemented by nitrous oxide occasionally. 6% dextrose and lactated-Ringer's solution were infused. For transfusion, whole blood was given to replace the operative blood loss. Dextran was also used to maintain adequate blood volume. Shortly before anastomosis of renal and femoral vessels, patients were haparinized. Fluids and electrolytes balance were studied pre-and post-operatively. Preoperatively, uremia and hyperpotassemia was corrected by several hemodyalysis. Urinary output after surgery showed a marked degree of diuresis up to 1800 ml/hr until second post-operative day. The special concern of anesthesia for kidney transplantation were: 1. Patients were suffering from severe uremia and metabolic disterbances. 2. Acidosis and hyperpotassemia should be corrected before surgery by hemo-or peritoneal dialysis. 3. Immunosuppressive agents made the patient less resistant to infection. 4. Anemia and hydrops was difficult to be corrected before surgery. 5. Muscle relaxants of choice were depolarizing agents, because of impaired renal excretion.
