Background: Deep vein thrombosis (DVT) is a major problem in the intensive care unit (ICU) patients, especially in Western countries. However; because the incidence of DVT in Asia ICU is lower, chemoprophylaxis (i.e., anticoagulant) is not routinely utilized. The aim of the present study was to identify the incidence and associated factors of DVT in Thai surgical ICU (SICU) patients without chemoprophylaxis., Material and Method: SICU patients admitted between June 2011 and July 2012 were screenedfor lower extremity DVT using doppler ultrasonography. Stepwise logistic regression was performed to identify associated factors for the development of DVT., Results: Three hundred andfive patients were included in the study, 174 were male (57%) and 131 were female (43%), with ages ranged from 15 to 99 years (mean 62.8 years). Eleven patients had DVT identified (DVT rate 3.6%), two of these had symptomatic pulmonary embolisms. The associated factors for the development of D VT were prior history of venous thromboembolism (p < 0.001, OR 34.3, 95% CI 14.6-80.5), orthopedics group (p < 0.001, OR 27.2, 95% CI 5.2-142.1), and female (p = 0.034, OR 14.3, 95% CI 1.7-102.5)., Conclusion: The incidence of D VT in Thai SICU patients was 3.6%. Further study is required to identify method and effectiveness of DVT prophylaxis in Asian ICU patients.

Background: Stem cell transplantation is a potential treatment to improve left ventricular ejection fraction (LVEF) after ST elevation myocardial infarction (STEMI). However, the outcomes still are controversial., Objective: To determine the 6-month LVEF of the patients who underwent intra-coronary bone marrow mononuclear cell (BMC) transplantation in patients with STEMI compared with controlled subjects., Material and Method: After successful percutaneous coronary intervention (PCI) in STEMI patients who had LVEF was less than 50% were randomized to intra-coronary BMC transplantation or control. Bone marrow aspiration of 100 cc was performed in the morning. After cellprocessing for three hours, the suspension of BMC about 10 cc were infused to infracted area using standard PCI technique. Balloon occlusion for three minutes was performed during cell infusion. Cardiac magnetic resonance imaging was used to determine LVEF scar volume and LV volume before and six-month follow-up., Results: Between September 2006 and July 2008, 23patients (11 in BMC group and 12 in control group) were enrolled. Mean BMC count before transplant was 420 x 10(6) cell with 96% viability. At six-month follow-up, New York Heart Association function class significantly improved in both groups (2.3 +/- 0.6 to 1.2 +/- 0. 4 for BMC and 2.3 +/- 0.7 to 1.3 +/- 0.5 for control group) but no difference was seen between groups. However, scar volume, wall motion score index, and LVEF did not show improvement after six months in both groups (33.7 +/- 7.7 to 33.5 +/- 7.6 for BMC and 31.1 +/- 7.1 to 32.6 +/- 8.3 for control group). No complication was observed during the procedure., Conclusion: BMC transplantation intra-coronary in patients with STEMI in KCMH was feasible and safe but LVEF improvement could not be demonstrated.

Background: Stem cell transplantation is a potential treatment to improve left ventricular ejection fraction (LVEF) after ST elevation myocardial infarction (STEMI). However technique and mode of transplantation, type of cells, number of cells, and when to transplant are still unknown., Objective: To determine the feasibility and safety of bone marrow mononuclear cell (BMC) intra-coronary transplantation and 6-months results in patients with STEMI., Material and Method: After successful percutaneous coronary intervention (PCI) in STEMI patients who did not have flow re-established within 12 hours and poor LVEF (less than 50%) by echocardiography were enrolled Bone marrow aspiration of 100 cc was performed in the morning. After cell processing for 3 hours, the suspension of BMC about 10 cc were infused to infarcted area using standard PCI technique. Balloon occlusion for 3 minutes was performed during cell infusion. Cardiac magnetic resonance imaging was used to determine LVEF scar volume and LV volume before and 6 months after transplantation., Results: Five patients were enrolled between May and August 2006. Duration of STEMI before transplantation ranged from 18 days to 14 years. Total amount of BMC ranged from 67 x 10(6) to 335 x 10(6). Number of CD 34 and CD 133+ cells were approximation to be 0.7 x 10(6) to 7.7 x 10(6) and 0.01 x 10(6) to 3.04 x 10(6). LVEF was increased from 36.4 at baseline to 43.3 at 6-month. NT pro-BNP level was decreased from 1105 ng/ml at baseline to 288 pg/ml at 6-month. No complications such as chest pain, no re-flow phenomenon, ventricular arrhythmia, or hypotension was detected during the procedure., Conclusion: Intra-coronary BMC transplantation in patients with STEMI in our center is feasible and safe. LVEF was slightly improved; however, a randomized controlled study is needed.
