Papillary muscle rupture with severe acute mitral regurgitation is a rare complication of acute myocardial infarction (AMI) that causes pulmonary congestion and cardiogenic shock. Moreover, it has a poor prognosis. Surgical intervention, including revascularization, is indicated; however, surgical mortality remains high. We report the case of an 85-year-old woman with cardiogenic shock from severe acute mitral regurgitation, in whom a hybrid intervention, combining percutaneous coronary intervention with mitral valve replacement via minithoracotomy, was performed after post-infarction papillary muscle rupture. She was discharged in a favorable clinical condition. We describe a novel hybrid intervention for treating a rare complication of AMI, which could minimize surgical invasion in elderly patients, prevent disuse syndrome after the intervention, and improve prognosis. However, mitral valve surgery via minithoracotomy for emergency cases requires technical proficiency, as well as collaboration with other healthcare professionals, and the choice to perform this procedure requires careful consideration.

Purpose: This study was aimed to develop the multicomponent intervention for preventing delirium among postoperative patients in a surgical intensive care unit (SICU). Methods: Using a quasi-experimental pre & post-test design with a non-equivalent control group, a total of 88 hospitalized patients in a SICU participated in this study. The 44 patients were allocated in each experimental and control group. The experimental group received the multicomponent intervention for delirium prevention including a delirium assessment and nursing intervention using a checklist, whereas the control group was provided with a standard care. The primary outcome of this study was the delirium incidence during the course of hospitalization. Results: There were no significant differences in the demographic and clinical characteristics between the two groups. The delirium occurred in 19.2% in the experimental group, whereas 38.6% in the control group ($x^2=4.526$, p<.05). Conclusion: The findings of the study demonstrated an effect of the multicomponent delirium prevention intervention in decreasing the delirium incidence rate over the standard care among the patients in SICU.

Objective : Acute subdural hematoma (ASDH) is generally considered a condition that should be managed surgically. However, some patients initially receive conservative treatment, a subset of whom require surgical intervention later. This study aimed to evaluate the predictors of delayed surgical intervention in ASDH patients who are initially managed conservatively. Methods : From January 2007 to December 2015, 842 patients diagnosed with ASDH were treated at our institution. Among them, 158 patients with convexity ASDH were initially treated conservatively. Patients were divided into a delayed surgery group and a conservative group. Demographic characteristics, past medication and medical histories, and radiological and laboratory data were collected by retrospective chart review. Independent risk factors were identified with univariate and multivariate analyses. Results : Twenty-eight patients (17.7%) underwent delayed surgical intervention. Their mean age was 69.0 years, and 82.1% were male. Hypertension, diabetes mellitus, and heart disease prevalence and use of anti-platelet agents did not significantly differ from the conservative group. However, age (p=0.024), previous cerebral infarction history (p=0.026), increased maximal hematoma thickness (p<0.001), midline shifting (p=0.001) and accompanying subarachnoid hemorrhage (p=0.022) on initial brain computed tomography (CT) scan, low hemoglobin level (p<0.001), high leukocyte count (p=0.004), and low glucose level (p=0.002) were significantly associated with delayed surgical intervention. In multivariate analysis, increased maximal hematoma thickness (odds ratio [OR]=1.279, 95% confidence interval [CI] 1.075-1.521; p=0.006), low hemoglobin level (OR=0.673, 95% CI 0.467-0.970; p=0.034), and high leukocyte count (OR=1.142, 95% CI 1.024-1.272; p=0.017) were independent risk factors for delayed surgical intervention. Conclusion : Due to the high likelihood of delayed surgical intervention among minimal ASDH patients with a thicker hematoma on initial brain CT, lower hemoglobin level, and higher leukocyte count, these patients should receive more careful observation.

Purpose: This study tested the effectiveness of brochure- and video-based education on managing surgical site infections by operating room health personnel. Methods: From April 20 to May 4, 2021, 34 operating room health personnel were subjected to training on surgical site infection management using brochures and educational videos. A survey was then conducted on knowledge, perception, and adherence regarding surgical site infection management. Results: After receiving training on surgical site infection management, the knowledge score increased significantly (15.15±2.09 vs.19.70±1.96, p<.001). However, the perception and adherence scores were already near perfect before the intervention and did not further increase after the intervention. Conclusion: It is necessary to develop and utilize continuous and substantive educational programs to improve perception and adherence of surgical site infection management.

It is well known that concentration of C-reactive protein(CRP) in the serum increase as nonspecific reaction of the various tissue injury. The CRP, synthesized in the hepatocyte, is one of 'acute phase proteins' in the serum. The main signal patterns of this protein are regulated by synthesis of interleukin-I secreted from macrophage in the area of tissue injury. Many studies were performed for quantitative analysis for CRP according to various surgical operation, but the study for fracture patients associated with trauma, especially in mandible, are rare. The mandible fracture have intrinsic danger for infection in oral bacteria associated with open wound in oral cavity, and, are difficult for detection of tissue reaction between surgical swelling and infection by facial swelling. In this study, quantitative analysis for CRP associated tissue injury in mandibular fracture and surgical intervention was done, the results were as follows: 1. After initial mandibular trauma, the value of serum CRP diminished sequentially, most high value was presented in post-traumatic 2 days. 2. The CRP was diminished significantly 2 days after surgical intervention, and maintained normal value in 5 days after surgery. 3. The change of CRP are higher value in surgical intervention than initial trauma, it suggested that tissue injury from surgery was severe than trauma. 4. The high value of CRP was obtained in mandibular fracture combined soft tissue injury than no associated soft tissue injury. 5. In measurement of CRP according to surgical approach, highest serum value in patients of combined intra-oral and extra-oral approach was showed, and intra-oral approach, extra-oral approach, in sequential orders. 6. The CRP value are more higher in patient of 2 fracture site than only one fracture site. From the results obtained in this study, CRP has showed different values in mandibular fracture associated with severity of tissue injury and surgical intervention, and quantitative analysis of CRP value in serum can be applied to the clinical management of mandibular fracture.

We report a case of primary undifferentiated cardiac sarcoma. The tumor originated from the left atrial free wall with multi-organ metastases, e.g., lung, and adrenal gland. The patient gradually grew worse with dyspnea and hemoptysis because of the obstructed left atrial outflow. Surgical resection of the left atrial sarcoma was undertaken to save the patient's life, followed by chemotherapy and brain irradiation as adjuvant therapy. The prognosis of cardiac sarcoma with metastases is very poor. However, in patients with hemodynamic instability, surgical intervention could be a therapeutic modality as palliation.

Background: The major limitation of arteriovenous graft access is the high incidence of thrombotic occlusion. This study investigated the outcomes of our salvage strategy for thrombosed hemodialysis arteriovenous grafts (including surgical thrombectomy with balloon angioplasty) and evaluated the efficacy of intragraft curettage. Methods: Salvage operations were performed for 290 thrombotic occluded arteriovenous grafts with clinical stenotic lesions from 2010 to 2018. Of these, 117 grafts received surgical thrombectomy and balloon angioplasty from 2010 to 2012 (group A), and 173 grafts received surgical thrombectomy and balloon angioplasty, with an additional salvage procedure using a curette and a graft thrombectomy catheter, from 2013 to 2018 (group B). Outcomes were described in terms of post-intervention primary patency and secondary patency rates. Results: The post-intervention primary patency rates in groups A and B were 44.2% and 66.1% at 6 months and 23.0% and 38.3% at 12 months, respectively (p=0.003). The post-intervention secondary patency rates were 87.6% and 92.6% at 6 months and 79.7% and 85.0% at 12 months, respectively (p=0.623). Multivariate Cox regression analysis demonstrated that intragraft curettage was a positive predictor of post-intervention primary patency (hazard ratio, 0.700; 95% confidence interval, 0.519-0.943; p=0.019). Conclusion: Surgical thrombectomy and balloon angioplasty showed acceptable outcomes concerning post-intervention primary and secondary patency rates. Additionally, intragraft curettage may offer better patency to salvage thrombotic occluded arteriovenous grafts with intragraft stenosis.

Purpose: This study was conducted to adapt the standardized evidence-based nursing protocol using the IPC (intermittent pneumatic compression) intervention to prevent venous thromboembolism in surgical patients. Further, an investigation was done to measure knowledge on prevention of venous thromboembolism, surrogate incidence of venous thromboembolism and to assess IPC compliance in the study patients compared with those in surgical patients who underwent IPC intervention due to previous clinical experience. Methods: An analysis was done of the nine modules suggested by National Evidence-based Healthcare Collaborating Agency (NECA) in the adaptation manual of the clinical practice guideline for protocol adaptation. A nonequivalent control group post test design as a quasi-experiment was used to verify the effect of the IPC protocol. Results: There was a significant difference in knowledge of prevention of venous thromboembolism, IPC application time after intervention and the number of IPC applications between the experimental group (n=50) using the IPC nursing protocol and the control group (n=49). However, the symptoms of deep vein thrombosis and pulmonary thromboembolism were not observed in either the experimental group or the control group after the intervention. Conclusion: Results confirm that the standardized IPC nursing protocol provides effective intervention to prevent venous thromboembolism in surgical patients.

Surgical intervention for pumlmonary tuberculosis has been controverted for last several decades. Although it is widely held that the chemotherapy is the best modality for treatment of pulmonary tuberculosis, surgical intervention has still some roles in well elected circumstance. At the National Kongju Tuberculosis Hospital in Korea, we performed a retrospective case Cohort study through the regular follow-up of 463 cases, who underwent the surgical intervention for pulmonary tuberculosis between January 1986 and April 1990. The results were as follows: 1) The male to female ratio was 1.8:1 and 84.4% of the patients were between 20 and 49 years of age. 2) According to the NAT classification, 6 cases (1.3%) were minimal, 216 (46.7%) moderately advanced and 241 (52%) far advanced. 3) One hundred and thirty four cases (28.9%) had the treatment history of 5 to 10 years and 129 cases (27.9%) of 3 to 4 years. 4) As for the pathologic entities, 172 cases (37.1%) had the totally destroyed lung and 137 (29.6%) destroyed lobe or segment. 5) A total of 238 cases (51.4%) underwent pneumonectomy and 153 (33.0%) lobectomy. 6) As the post-operative complications, 21 cases (4.5%) had empyema and 11 (2.4%) bleeding. The rate of complication after pneumonectomy and lobectomy was 5.8% and 3.2%, respectively. 7) Six cases (1.3%) died post-operatively. 8) Out of 238 cases with pre-operative positivity for AFB, 212 achieved the negative conversion, its rate being 89.1%. It follows from these results that although it has a limit, surgical intervention may play an important role in treating some patients with pulmonary tuberculosis.

Anxiety is a common preoperative problem in cesarean section candidates. Nonpharmacologic anxiety control has been demonstrated to be more suitable in pregnant women. The current study was a randomized, single-blind clinical trial which evaluated the effect of acupressure on preoperative C-section anxiety. In this study, 60 patients facing surgery were randomly divided into two groups of 30 patients each. Those patients in the intervention group received simultaneous acupressure at the Yintang and HE-7 acupoints for 5 minutes before surgery, and patients in the control group received intervention at a sham acupoint. The anxiety level of patients was preoperatively assessed twice using the Spielberger's State-Trait Anxiety Inventory. The mean anxiety scores of the two groups were shown to be insignificantly different before the intervention (p = 0.859), whereas a significant difference between the mean anxiety scores of the two groups was observed after the intervention (p = 0.001), suggesting that acupressure reduced the anxiety of patients before surgery.
