  • Background: To investigate the effects of preemptive analgesia with parecoxib sodium on haemodynamics and plasma stress hormones in surgical patients with thyroid carcinoma. Materials and Methods: Fifty-seven patients with thyroid carcinoma who underwent thyroidectomy selectively in Laiwu Hospital Affiliated to Taishan Medical University and Binzhou People's Hospital were selected and randomly divided into three groups, 19 cases in each group. The control group was intravenously injected 0.9% sodium chloride injection before anesthesia induction; trial group I was intravenously injected with parecoxib sodium 20 min before anesthesia induction; based on trial group I, trial group II was injected with parecoxib sodium again 12 h after surgery. The levels of plasma norepinephrine (NE), cortisol (Cor) and blood glucose before, 12 and 24 h after surgery and changes of haemodynamics before surgery, at the end of surgery and 12, 24 and 48 h after surgery were compared in the three groups. Besides, visual analogue scale (VAS) scores were recorded 4, 8, 12 and 24 h after surgery. Results: 12 and 24 h after surgery, the levels of plasma NE and Cor in three groups rose dramatically (P<0.05 or (P<0.01); The levels of plasma NE and Cor in trial groups I and II were evidently lower than in control group (P<0.05 or P<0.01), and those in trial group II slightly lower than in trial group I. 12 h after surgery, the heart rates (HR) and systolic pressures (SBP) in trial groups I and II increased obviously by comparison to surgery before (P<0.05 or P<0.01), but gradually returned to the preoperative level. HR, SBP and diastolic pressures (DBP) in trial groups I and II at the end of surgery and 12 h after surgery were all lower than in the control group, and significant differences were present (P<0.05 or (P<0.01). At 4, 8, 12 and 24 h after surgery, VAS scores in trial groups I and II were markedly lower than in the control group (P<0.05 or (P<0.01), the scores in trial group II being the lowest. Conclusions: Combined application of parecoxib sodium for preemptive analgesia before anesthesia and after surgery can effectively reduce the levels of plasma stress hormones and improve analgesic effects in surgical patients with thyroid carcinoma, and without conspicuous impact on haemodynamics.

  • Congenital aortic stenosis in children is characterized by "excessive" left ventricular hypertrophy with reduced left ventricular systolic wall stress that allows for supernormal ejection performance. We hypothesized that left ventricular wall stress was decreased immediately after surgical correction of pure congenital aortic stenosis. Also measuring postoperative left ventricular wall stress was a useful noninvasive measurement that allowed direct assessment for oxygen consumption of myocardium than measuring the peak systolic pressure gradient between ascending aorta and left ventricle for the assessment of surgical results. Material and Method: Between September 1993 and August 1999, 8 patients with isolated congenital aortic stenosis who underwent surgical correction at Yonsei cardiovascular center were evaluated. There were 6 male and 2 female patients ranging in age from 2 to 11 years(mean age, 10 years). Combined Hemodynamic-Ultrasonic method was used for studying left ventricular wall stress. We compared the wall stress peak systolic pressure gradient and ejection fraction preoperatively and postoperatively. Result: After surgical correction peak aortic gradient fell from 58.4${\pm}$17.6, to 23.7${\pm}$17.7 mmHg(p=0.018) and left ventricular ejection fraction decreased but it is not statistically significant. In the consideration of some factors that influence left ventricular end-systolic wall stress excluding one patient who underwent reoperation for restenosis of left ventricular outflow tract left ventricular end-systolic pressure and left ventricular end-systolic dimension were fell from 170.6${\pm}$24.3 to 143.7${\pm}$27.1 mmHg and from 1.78${\pm}$0.4 to 1.76${\pm}$0.4 cm respectively and left ventricular posterior wall thickness was increased from 1.10${\pm}$0.2, to 1.27${\pm}$0.3cm but it was not statistically singificant whereas left ventricular end-systolic wall stress fell from 79.2${\pm}$24.9 to 57.1${\pm}$27.6 kdynes/cm2(p=0.018) in 7 patients. For one patient who underwent reoperation peak aortic gradient fell from 83.0 to 59.7 mmHg whereas left ventricular end-systolic wall stress increased from 67.2 to 97.0 kdynes/cm2 The intervals did not change significnatly. Conclusion ; We believe that probably some factors that are related to left ventricular geometry influenced the decreased left ventricular wall stress immediately after surgical correction of isolated congenital aortic stenosis. Left ventricular wall stress is a noninvasive measurement and can allow for more direct assesment than measuring peak aortic gradient particularly in consideration of the stress and oxygen consumption of the myocardium therefore we can conclude it is a useful measurement for postoperative assessment of congenital aortic stenosis.

  • Oral cancer surgery changes the morphologic characteristics of the human upper airway. These changes can affect the flow patterns. In this study, computational fluid dynamics (CFD) simulations with transient solver were performed to numerically investigate the air flows in the human upper airways depending oral cancer surgery. 3D reconstructed models were obtained from 2D CT images of one patient. For the boundary condition, the realistic breathing cycle of human was applied. The hydraulic diameters of cross-sections for post-surgical model are changed greatly along streamwise direction, so these variations can cause higher wall shear stress and flow disturbance compared to pre-surgical model. The recirculation flows observed in the protruding region result in the relatively large pressure drop. These results can be helpful to understand the flow variations after resection surgery of oral cancer.

  • Very few studies regarding the effects of preoperative nursing intervention on children's welfare after surgery have been conducted. The purpose of this study was 1) to evaluate the effects of preoperative nursing instructions on children's physical recovery and emotional state after surgery and 2) to analyse the relationship between the effects of preoperative nursing instructions and the age and general anxiety of child. The study was conducted flow: August 15th to October 30th at Severance Hospital, Seoul, Korea. A total of 41 Pediatric surgical Patients, between the age of 4 to 14, participated in the study. Twenty patients, randomly selected, were visited by the experimenter in the evening before, surgery and received specific preoperative nursing instructions. These instructions were designed to alleviate emotional stress and were adopted to the age of child. The postoperative recovery of these patients were then compared with a randomly selected control group of 21 patients who received only the routine preoperative care by the staff in the hospital Dependent variable were vomiting, pain medication, ability to void, elevation of temperature, infection, the between surgery and hospital discharge and postoperative emotional stress which was measured by the vital signs. Because of the limitation of the sample size it was difficult to obtain valid statistical results. However, the analysis of the raw data indicates that: 1) the preoperative nursing instructions appears to promote physical recovery and it seems especially effective in preventing elevation of temperature and shortening the length of the hospital stay, 2) the preoperative nursing instruction also seems to be effective in relieving the child's emotional stress(situational anxiety) after surgery, 3) the patient's general anxiety level preparatively seems to be a predictor of postoperative problems, 4) the preoperative nursing instructions were an effective means of promoting physical recovery in every age group as long as the child understood the instructions. The above data would seem to indicate that all preoperative pediatric patients four years of age or older, if they can understand, should have preoperative nursing instruction in order to alleviate postoperative stress and enhance physical recovery. The level of general anxiety preparatively deserves special attention since the amount of nursing instruction needed seems to vary with tile level of anxiety.

  • 메기, Silurus asotus의 외과적 시술시 상처 회복 및 스트레스 반응을 알아보기 위하여, 수술 과정에 의한 스트레스 호르몬의 변화 양상과 회복과정을 분석하였다. 수술 후 clove oil (1,000 ppm) 마취한 군의 생존율은 수술 후 3~42일 동안 약 90%를 보였으며 무마취군은 약 74%를 보였다. 즉, 마취를 한 후 수술하였을 때 무마취군 보다 생존율이 높게 나타났다. Clove oil로 마취한 군의 혈장 cortisol 농도가 무마취군 보다 높았으며(P<0.05) 아울러, clove oil로 마취한 군의 혈장 lactic acid 농도 역시 무마취군 보다 높았다(P<0.05). 수술 후 14일과 28일째는 아직 봉합사의 흔적이 남아 있었고 움직임도 활동적이지 않았지만 35일째 되었을 때는 봉합자국은 사라졌고 수술 후 42일에는 봉합사도 관찰되지 않았으며, 봉합 상처도 회복이 되었다. 따라서 메기의 외과시술시, 마취를 한 후 수술하였을 때 무마취군 보다 생존율이 높게 나타났고, 수술 후 받는 스트레스 양도 적다는 것을 알 수 있다. 즉, 본 연구의 메기에서의 외과적 상처 회복은 마취제 사용시 성공적으로 이루어짐을 보였다.

  • Background Reconstruction of combined orbital floor and medial wall fractures with a comminuted inferomedial strut (IMS) is challenging and requires careful practice. We present our surgical strategy and postoperative outcomes. Methods We divided 74 patients who underwent the reconstruction of the orbital floor and medial wall concomitantly into a comminuted IMS group (41 patients) and non-comminuted IMS group (33 patients). In the comminuted IMS group, we first reconstructed the floor stably and then the medial wall by using separate implant pieces. In the non-comminuted IMS group, we reconstructed the floor and the medial wall with a single large implant. Results In the follow-up of 6 to 65 months, most patients with diplopia improved in the first-week except one, who eventually improved at 1 year. All patients with an EOM limitation improved during the first month of follow-up. Enophthalmos (displacement, 2 mm) was observed in two patients. The orbit volume measured on the CT scans was statistically significantly restored in both groups. No complications related to the surgery were observed. Conclusions We recommend the reconstruction of orbit walls in the comminuted IMS group by using the following surgical strategy: usage of multiple pieces of rigid implants instead of one large implant, sequential repair first of the floor and then of the medial wall, and a focus on the reconstruction of key areas. Our strategy of step-by-step reconstruction has the benefits of easy repair, less surgical trauma, and minimal stress to the surgeon.

  • Purpose: To examine the effects of the environmental nursing intervention using eye-shields and earplugs on the incidence of delirium, environmental stress and sleep among the patients with open-heart surgery in the post-cardiac ICU(intensive care units). Method: This study was a non-equivalent control group non-synchronized design. The subjects consisted of 93 patients who received ICU care after the cardiac surgery. Among those, 32 subjects was assigned in one experimental group with eye-shields, 31 in the other experimental group with earplugs, and 30 in the control group. ICU delirium was measured by CAM-ICU, environmental stress by ICUESS, and sleep by two sleep scales developed by Oh, et al. and Kim. The data were analyzed by the SPSS 13.0 program including frequency, percentage, t-test, $x^2$ test, ANOVA and ANCOVA. Results: There are no statistically significant differences in the incidence of delirium among three groups (p=.139). The ICU environmental stress scores from the subjects of two experimental groups demonstrated lower (F=6.731, p=.002) than the control group. Also, the degrees of sleep pattern (p=.000, p=.000) and sleep satisfaction (p=.000, p=.000) were greater than those of the control group. Conclusion: Although the environmental nursing intervention using eye-shields and earplugs did not demonstrate the effects in decreasing the incidence of ICU delirium, it has affirmative effects in decreasing environmental stress and improving the quality sleep among the patients with open-heart surgery while they stay in ICU. Further nursing implications are discussed.
