We utilized pulmonary artery pressure monitoring system in risky patients for preventing the postoperative pulmonary hypertensive crisis and for sampling the mixed venous blood. And this mixed venous blood oxygen saturation [MVSO2] or partial pressure [MVPO2]tells us many meaningful patients state. We selected 59 cyanotic congenital heart diseased patients, who were operated in our hospital from Nov. 1987 to Oct. 1988, in the Department of Thoracic and Cardiovascular Surgery, Seoul National University Children\ulcorner Hospital, who had pulmonary artery pressure monitoring catheter and who made us know their mixed venous oxygen condition. We found that there was no close relationship between MVPO2 and Cardiac Index [C.I.] during early postoperative period, but on the first and second day after operation the correlation coefficient was increased as r=0.35[p=0.008], r=0.78[p=0.0001]. So we concluded that the correlation between MVPO2 and C.I. was more reliable with time going as hemodynamic stabilization. And we experienced no survivors whose MVPO2 was under 20 torr, but that was not the only factor for death. From these results, we conclude that we can consider the MVPO2 [or MVSO2] representing C.I. after stabilized postoperative condition of the open heart surgery patients, but during early postoperative period, in addition to this MVPO2, we should do also apply other parameter such as urine output, arterial blood pressure, left atrial pressure and pulmonary arterial pressure for exact estimation of the patients status.

Renal dysfunction is a common complication of open-heart surgery: a form of controlled hemorrhagic shock, and successful perioperative management of renal dysfunction depends on recognition of the risk factors and optimal management of factors influencing renal function, including cardiopulmonary bypass, and early detection of renal failure. Changes in renal functional parameters including Ccr, Cosm, CH2O, FENa, and RFI were observed prospectively in forty five patients operated on at Dept. of Thoracic and Cardiovascular Surgery, S.N.U.H., from April to June, 1985. They were 23 males and 22 females with 35 acquired and 10 congenital heart diseases and the mean age and body surface area of them were 38.010.3 years [22-63] and 1.5518 M2[1.151.92] respectively. Followings are the conclusion. 1. The Ccr, representative of renal function, is significantly improved from 90.231.3 ml/min/M2 preoperatively to 101.536.4 ml/min/M2 postoperative and day [P<0.05], and all patients were classified as postoperative renal functional class I of Abel, which representing adequate renal protection during our cardiopulmonary bypass. 2. The Cosm is significantly elevated at immediate postperfusion time and remained high at postoperative one day representing osmotic diuresis at that time, but CH2O shows no significant changes at immediate postperfusion period and is decreased significantly at postoperative one day, representing recovery of renal concentrating ability at that time with decreasing urine flow. 3. The absolute value and changing tendency in FENa and RFI during perioperative period shows no diagnostic reliability on these parameters, but those of CH2O appear to reveal future renal function more accurately than Ccr 4. The depth of hypothermia may be protective upon renal function against the ill effects of prolonged nonpulsatile cardiopulmonary bypass. 5. The depth of the hypothermia, pump time of more than 150 minutes, poor cardiac function, and intraoperative events such as embolism appear to be related with immediate postperfusion renal function. 6. Hemoglobinuria and hemolysis, poor preoperative renal function, history of cardiac surgery, and massive transfusion associated with bleeding appear not to be related with renal dysfunction.

Rumen cannulation is used for nutritional and microbiological research, clinical diagnosis, and rumen component transfaunation. However, the cannulation procedure can affect parameters such as complete blood count findings, serum chemistry, and rumen fluid pH. The objective of this study was to evaluate the health risks related to the rumen cannulation procedure over a 1-month period. We did not identify significant differences in red blood cell numbers or morphologies between pre- and postoperative timepoints. Moreover, no inflammation or infection was detected. Despite the absence of apparent clinical signs after surgery, serum chemistry results revealed changes in blood urea nitrogen levels and the activities of liver enzymes, including aspartate transaminase, lactate dehydrogenase, and creatinine kinase, from postoperative days 1 to 14. Rumen fluid pH, as measured from samples collected via an orogastric tube, was slightly increased after a preoperative fasting period and on postoperative day 1 but decreased thereafter from postoperative day 4, indicating a minor influence of cannulation surgery on ruminal fluid pH. This is the first study to evaluate hematological parameters and rumen pH before and after rumen cannulation surgery in Hanwoo cattle. Further research is required to better elucidate the potential effects of rumen cannulation surgery on animal health.

Background: Prospective clinical study of blood lactate concentration in horses undergoing colic surgery is needed to determine utility in outcome prediction. Objectives: To evaluate venous lactate measurements in horses following colic surgery, including immediately after anesthetic recovery and daily throughout hospitalization, as well as to determine if lactate concentrations were significantly higher in horses that developed postoperative complications or did not survive to hospital discharge. Methods: Horses > 1 year of age undergoing surgery for colic and recovered from general anesthesia were sampled. A portable lactate meter was used to measure venous samples collected immediately following anesthetic recovery and daily throughout hospitalization. Complications arising during hospitalization and survival to hospital discharge were recorded. Results: Fifty one horses were enrolled, ranging in age from 2 to 29 years. Lactate concentration immediately following anesthetic recovery was higher in horses that developed complications during hospitalization (p = 0.046). The odds of developing complications postoperatively were doubled for horses with a venous lactate concentration > 5 mmol/L. Lactate measurements in non-survivors were significantly higher compared to survivors by 96 h postoperatively (p < 0.006). Conclusions: Higher venous lactate concentrations in the postoperative colic period were associated with an increased risk of complications and death. Results suggest horses with higher venous lactate measurements in recovery are more likely to have postoperative complications, with the odds of developing complications doubled for horses with a venous lactate > 5 mmol/L. Evaluation of venous lactate could provide information on prognosis in the postoperative period for horses with surgical colic.

Objectives: The purpose of this study is to report the effectiveness of Korean medicine treatment on postoperative state patients with cervical spinal cord injury due to ossification of the posterior longitudinal ligament. Methods: A 55-year-old Korean male patient diagnosed with cervical spinal cord injury due to ossification of the posterior longitudinal ligament was treated in an inpatient setting with Korean medicine treatment consisting of herbal medicine, acupuncture, and others from May 22 to August 21. The outcome was evaluated with the American Spinal Injury Association Impairment Scale (AIS), Spinal Cord Independence Measure-III (SCIM-III), modified Japanese Orthopaedic Association scale (mJOA), Numeric Rating Scale (NRS) before and after, or during the treatment period. Results: After 92 days of treatment, the patient's scores on all scales improved. Conclusion: The results suggest that Korean medicine treatment may be effective for postoperative patients with cervical spinal cord injury due to ossification of the posterior longitudinal ligament. Further studies should be conducted on a larger number of patients.

Purpose: Although surgical arthroscopic repair of rotator cuff has become much more common as surgeons have developed proficient techniques, it is still technically difficult. The purpose of this study was to evaluate the clinical results and the usefulness of mini-open repair in large and massive size tears. Materials & Methods: From January 2000 to December 2004, sixteen patients were treated with mini-open repair. There were 10 male and 6 female patients with the average age of 62.5 years. The size of tear was massive in 4 cases and large in 12 cases. All tears were repaired with metal anchor sutures. The mean duration of follow-up period was 23 months. Postoperative results were evaluated based on American Shoulder and Elbow Society scoring system. Results: Five patients showed excellent results, five good, and two fair in large tears while one patient showed excellent result, one good, and two fair in massive tears. Poor outcome was not seen during the follow-up period. There was no significant relationship between the patient's age and the size of tear, and postoperative results. However, the relationship between the duration of symptomatic period in preoperation and postoperative results showed significant correlation. Conclusion: Mini-open repair combined with the preservation of deltoid and early rehabilitation is clinically useful in large and massive size rotator cuff tear patients treatment.

A series of 19 cases with maxillary hyperplasia and mandibular retrognathia were operated on by simultaneous superior repositioning of the maxilla after Le Fort I osteotomy and anterior repositioning of the mandible after bilateral sagittal split ramus osteotomies with or without osteotomy of the inferior border of the mandible. These were evaluated by retrospective cephalometric and computer analysis for the longitudinal skeletal and dental changes for an average of 17.1 months after surgery. For stabilization of the osteotomized segments, the authors used wire osteosynthesis by means of bilateral infraorbital and zygomatic buttress suspension wire at the maxilla, and direct interosseous wire at the split segments of the mandibular rami. Results show generally good stability after simultaneous maxillary and mandibular surgery with wire osteosynthesis, and a minimal to moderate tendency toward skeletal and dental relapse. This article is a preliminary study to defy the efficiency of the wire osteosynthesis (wo)compared with rigid internal fixation (RIF) for simultaneous maxillary and mandibular surgery. 1. The vertical relapse rate of the A point after superior repositioning of the maxilla is 2.2%. 2. The horizontal relapse rate of the B point after advancement of the mandible is 18.3%. 3. The condyle is distracted inferiorly and slightly posteriorly at the immediate postoperative period. 4. At the long term follow up examination, the condyle presents tendency of return to the preoperative position. 5. Condylar segment angle is decreased at the immediate postoperative period, and at the long term follow up evaluation, the angle is increased. 6. Gonial angle is increased at the immediate postoperative period, and then is decreased at the long term follow up evaluation. 7. The dentition is satisfactory with acceptable movement at the long term follow up evaluation. 8. At the mandibular free body analysis, genioplasty shows good stability. 9. Wire osteosynthesis provides excellent stabilization for the simultaneous maxillary and mandibular surgery.

The objective of this research was to evaluate the relationships of preoperative (Pre-OP) levels of hematological and biochemical indices to perioperative variables in patients that underwent coronary artery bypass graft surgery (CABG). Pre-OP levels of hematological factors [total white blood cells (T-WBC), erythrocytes, hemoglobin, hematocrit, glycohemoglobin A1c (HbA1c), or platelet] were negatively or positively related with biochemical indices [alanine aminotransferase (ALT), bilirubin, glucose, fructosamine, triglyceride, and high density lipoprotein cholesterol (HDL)]. Pre-OP levels of hematological factors and biochemical indices were negatively or positively correlated with echocardiographic variables. Pre-OP level of HbA1c had a relationship with C-reactive protein. Pre-OP levels of aspartate aminotransferase (AST), ALT, HDL, glucose, fructosamine, or blood urea nitrogen (BUN) were positively or negatively associated with Pre-OP levels of cardiac markers (brain natriuretic peptide, troponin-I, creatine kinase isoenzyme 2, or CRP). Pre-OP levels of hematological factors (excepting T-WBC) related with operation time (OPT), postoperative mechanical ventilation time (POMVT), intensive care unit-period (ICU-period) or hospitalization. Pre-OP levels of AST, ALT, bilirubin, triglyceride, HDL, low dwensity lipoprotein, fructosamine, or BUN were positively or negatively correlated with OPT, graft numbers, POMVT, ICU-period or hospitalization. Retrospective this study reveals that Pre-OP levels of hematological and biochemical markers are associated with echocardiographic variables, several cardiac markers and postoperative outcomes, suggesting that Pre-OP levels of hematological and biochemical markers may be useful predictors for the diagnosis and prognosis of coronary artery disease.

Purpose: The purpose of this study was to provide nursing intervention with basic data extracted through investigating self-care and nursing of lymphedema in patient who have had a mastectomy. Method: The subjects for this study consisted of 214 mastectomy patients in 2 hospitals. The data were collected from December 1, 2004 to February 28, 2005. The instruments used for this study were both the Self-care Practice Scale by Cho, Myoung-Ok et al.(2003) which we modified and the Nursing Evaluation Scale developed by the researchers. Results: The mean score of self-care on lymphedema was $59.96{\pm}12.46$ The mean score of nursing was $25.64{\pm}9.25$ Factors influencing the self-care were the postoperative period (F=17.505, p<.001), the location of the tumor (F=3.826, p=.023), menstruation (t=7.333, p=.007), and complications (F=5.427, p<.001). Conclusion: Self-care and nursing care on the lymphedema management were shown to be lower than expected. Especially, the score of self-care was the lowest in the more than 3 year postoperative period. Therefore, the longer the postoperative period is, the more active management on lymphedema needs to be. Also, education should be given to both nurses and patients on the importance of self-care on lymphedema with mastectomies.

Background: The purpose of this study was to evaluate the efficacy of suction drain use following arthroscopic rotator cuff repair by comparing early pain score and range of motion (ROM) between groups with and without suction drains. Methods: The study included 153 patients with rotator cuff tears who underwent arthroscopic repairs at our clinic from April 2014 to March 2015. Following surgery, a suction drain was used in 85 patients (group D) and not used in 68 patients (group ND). There was no statistical difference between the groups in terms of age, gender, or total operation time. The clinical outcome with regard to pain (assessed by pain scores and analgesic requests) and passive ROM was assessed preoperatively and postoperatively. Results: Immediate postoperative analgesic requirement was significantly higher in group D (p=0.001), although there was no difference in pain outcomes between the groups during the 3-month follow-up period. A statistically significant difference in passive ROM was observed at the postoperative 2- and 6-week follow-ups (p=0.036, 0.035, and 0.034 in forward elevation (FE), external rotation at the side (ER) and 90 ER at weeks 2, respectively; 0.045 and 0.009 in FE and ER at weeks 6, respectively); however no significant difference was observed at the end of 3 months. During the study period, no complication was reported in either group. Conclusions: Use of suction drains after arthroscopic rotator cuff repair provided little benefit in terms of ROM or pain in the early postoperative period (up to 3 months).
