Background: We aimed to investigate the preoperative, operative, and postoperative factors affecting intra-aortic balloon pump (IABP) insertion in patients undergoing isolated on-pump coronary artery bypass grafting (CABG). We also investigated factors affecting morbidity, mortality, and survival in patients with IABP support. Methods: Between January 2002 and December 2009, 1,657 patients underwent isolated CABG in Izmir Katip Celebi University Ataturk Training and Research Hospital. The number of patients requiring support with IABP was 134 (8.1%). Results: In a multivariate logistic regression analysis, prolonged cardiopulmonary bypass time and prolonged operation time were independent predictive factors of IABP insertion. The postoperative mortality rate was 35.8% and 1% in patients with and without IABP support, respectively (p=0.000). Postoperative renal insufficiency, prolonged ventilatory support, and postoperative atrial fibrillation were independent predictive factors of postoperative mortality in patients with IABP support. The mean follow-up time was $38.55{\pm}22.70$ months and $48.78{\pm}25.20$ months in patients with and without IABP support, respectively. The follow-up mortality rate was 3% (n=4) and 5.3% (n=78) in patients with and without IABP support, respectively. Conclusion: The patients with IABP support had a higher postoperative mortality rate and a longer length of intensive care unit and hospital stay. The mid-term survival was good for patients surviving the early postoperative period.

Purpose: The purpose of this study was to identify the impact of practical communication strategies (PCS) on the reduction of AEs (Adverse Events) in pediatric cardiac ICU (PCICU). Methods: Intra-operative findings and care plans were documented and shared between staff members on a daily basis from the day of operation to the day of general ward transfer. Incidence of AEs was investigated in all patients who were admitted to the PCICU and was compared with incidence of AEs one year after establishment of PCS. Results: The study population consisted of 216 patients in pre-PCS group and 156 patients in post-PCS group. Incidence of readmission decreased from 6.0% (13/216) in pre-PCS group to 0.6% (1/156) in post-PCS group (${\chi}^2=7.23$, p=.010). Incidence of other major complications decreased from 4.2% (9/216) to 0.6% (${\chi}^2=6.66$, p=.012). Minor AEs such as intervention omission, order error, and protocol misunderstanding were reduced from 23.3 cases per 100 patient-days to 7.5 cases per 100 patient-days (${\chi}^2=20.31$, p<.001). Conclusion: Handover protocol is an effective strategy to reduce AEs for critically ill patients after pediatric cardiac surgery. Efforts to develop effective communication strategies should be continued and outcome research about communication strategies for patient safety should be further studied.

Purpose: The purpose of this study was to identify the relationship between intraoperative level of caring and anxiety among patients who underwent spinal surgery under local anesthesia. Methods: The study participants included 162 patients who had spinal surgery under local anesthesia at a general hospital in B metropolitan city between July 20 and September 20, 2014. To measure the caring behaviors of patients under local anesthesia, we used the Caring Behavior Measurement, and state anxiety was measured by the State Trait Anxiety Inventory. The collected data were analyzed using a SAS program. The differences in anxiety levels based on participants' characteristics were analyzed with t-test and an analysis of variance. The correlation between levels of caring and anxiety was tested with Pearson's correlation coefficient. Results: Education and caring levels showed significant relationship with the anxiety level of patients with spinal surgery under local anesthesia. Conclusion: To decrease the level of anxiety in patients undergoing spinal surgery under local anesthesia, it is necessary to educate and train operating nurses about the intra-operative caring behavior.

We prospectively studied postoperative cardiac arrhythmia after open heart surgery to analyze the types and incidence of cardiac arrhythmia and to predict preoperative risk factors. And also we evaluated the effectiveness of atrial and ventricular epicardial electrodes which were placed during operation Between March 1990 and August 1990, We had operated on in 211 patients and we studied 201 consecutive patients excluding 10 patients. The study group included 99 males and 102 female patients, ages 1 month to 75 years[Mean$\pm$SD=28.0$\pm$21.7 years]. Postoperatively, all patients were regularly seen by the cardiac surgeon and cardiologist, They had continuous electrocardiographic monitoring for the first 3 days, initially in the intensive care unit and were checked routine electrocardiography on the postoperative 7 days, The postoperative cardiac arrhythmia were analyzed and possible associations of this arrhythmia with various pre, intra, and postoperative factors were studied by univariate and multivariate discriminant analysis, The overall incidence of postoperative cardiac arrhythmia except relative sinus bradycardia was 36.8%;[74/201], The incidence of postoperative cardiac arrhythmia in acyanotic congenital heart disease: 19.4%, cyanotic congenital heart disease: 20.8%, cardiac arrhythmia surgery: 33.3%, acquired valvular heart disease: 60.9% and coronary artery occlusive disease: 38.9%. Both univariate and multivariate studies indicated the pre operative symptom duration[p = 0013], the duration of medication[p=0.003], presence of preoperative arrhythmia[p<0.001] and pre-operative left atrial dimension in echocardiography to be the factor promoting postoperative cardiac arrhythmia. Multivariate discriminant analysis showed that the presence of preoperative cardiac arrhythmia, bypass time and the duration of preoperative symptom duration conveyed considerable risk factor on post-operative arrhythmia. The atrial wire electrodes were used diagnostically in 36 and were used therapeutically in 89 among 201 patients. Atrial pacing were used to treat relative sinus bradycardia, accelerated junctional tachycardia or premature atrial or ventricular contractions in 51 patients. Atrioventricular sequential pacing were used in 16 patients and ventricular pacing were used in 20 patients. Hemodynamics were evaluated in 2 patients of relative sinus bradycardia before and after atrial pacing. The atrial pacing increased the amount of cardiac output to 15% more. Because of their great utility in the diagnosis and treatment of arrhythmias, we conclude that routine placement of atrial and ventricular electrodes at the time of operation is indicated regardless of the nature of the open-heart procedure.

Background: Surgeon satisfaction and patient analgesia during the procedure of laparoscopic surgery are important issues. The aim of this work was to study if an intrathecal (IT) Bupivacaine combined with Magnesium sulfate may or may not provide good surgeon satisfaction in addition to improvement of intraoperative and postoperative analgesia. Methods: Sixty female patients were enrolled in this prospective, randomized, double-blind controlled clinical trial study. All patients were operated for gynecological laparoscopic surgery under spinal anesthesia. Patients were divided into two groups (Bupivacaine and Magnesium). Group Bupivacaine (30 patients) received intrathecal Bupivacaine 0.5% only (15 mg), while 30 patients in group Magnesium received intrathecal Bupivacaine (15 mg) in addition to intrathecal Magnesium sulfate (50 mg). The sensory block level, the intensity of motor block, the surgeon satisfaction, the intraoperative visual analog scale (VAS) for pain assessment, the postoperative VAS, and side effects were recorded during the intraoperative period and within the first 24 hours after surgery in the post-anesthesia care unit. Results: Surgeon satisfaction, intraoperative shoulder pain, postoperative pain after 2 h, and perioperative analgesic consumption (ketorolac) were significant better in group Magnesium than in group Bupivacaine. (P < 0.05). The onset of motor and sensory blocks was significant longer in group Magnesium than the other one. The incidence of PONV, pruritus and urinary retention was insignificant statistically between both groups. Conclusions: Magnesium sulfate if used intrathecally as an adjuvant to Bupivacaine would provide a better surgeon satisfaction and would improve the analgesic effect of spinal anesthesia used for gynecological laparoscopic surgery.

Purpose: Anterolateral minimally invasive plate osteosynthesis (MIPO) was performed to treat patients with distal tibial fractures associated with open fractures or extensive soft tissue injuries, which is limited medial MIPO. The treatment results of the anterolateral MIPO technique were evaluated and analyzed. Materials and Methods: Seventeen patients with distal tibial fractures associated with an open fracture or large bullae formation on the distal tibia medial side were treated with anterolateral MIPO using anterolateral locking plates. Within 24 hours of visiting the emergency room, external fixation was applied, and the medial side wound was managed. After damage control, the anterolateral locking plate was applied using an anterolateral MIPO technique. The union time, nonunion, or malunion were evaluated with regular postoperative radiographs. The ankle range of motion, operative time, blood loss, Iowa score, and wound complications were investigated. Results: Radiological evidence of bony union was obtained in all cases. The mean time to union was 16.7 weeks (12~25 weeks). The mean operation time was 44.0 minutes. Regarding the ankle range of motion, the mean dorsiflexion was 15°, and the mean plantarflexion was 35°. Satisfactory results were obtained in 15 out of 17 cases; five results were classified as excellent, four were good, and six were fair. The mean blood loss was 125.2 mL. Two complications were recorded. Conclusion: In distal tibial fractures with severe medial soft tissue damage caused by high-energy trauma, the staged anterolateral MIPO technique using anterolateral locking plates is a useful alternative treatment to achieving optimal wound care, rapid union with biological fixation, and intra-articular reduction.

Purpose: This study was performed to evaluate the effect of low-dose lidocaine on fentanyl-induced cough and hemodynamic changes under general anesthesia. This research was a randomized trial design and performed using a double-blind method. Methods: Data collection was performed from October 22, 2008, to May 4, 2009. One hundred and thirty two patients were randomly assigned to control group (Con G) and experimental group (Exp G) using a table of random numbers. Exp G (n=66) were administered 0.5 mg/kg lidocaine and Con G (n=66)) were administered saline. The occurrence of cough and vital sign were recorded within one minute after fentanyl bolus by an anesthesiologist. Collected data were analyzed using Repeated measures ANOVA using SPSS for Windows (Version 17.0). Results: The incidence of cough in Exp G was 13.6%, while Con G was 53%. The incidence cough in Exp G was significantly lower compared to Con G (p<.001). Lidocaine seemed not to suppress mean arterial pressure (p=.145), heart rate (p=.508), and oxygen saturation (p=.161). Conclusion: Intravenous administration of 0.5 mg/kg lidocaine seems to suppress fentanyl-induced cough without affecting mean blood pressure, heart rate and oxygen saturation. Therefore, we recommend intravenous 0.5 mg/kg lidocaine administration to suppress fentanyl-induced cough under general anesthesia.

Background: With growing attention to the aortopathy associated with aortic valve diseases, the number of candidates for accompanying ascending aorta and/or root replacement is increasing among the patients who require aortic valve replacement (AVR). However, such procedures have been considered more risky than AVR alone. This study aimed to compare the surgical outcome of isolated AVR and AVR combined with aortic procedures. Materials and Methods: A total of 86 patients who underwent elective AVR between 2004 and June 2010 were divided into two groups: complex AVR (n=50, AVR with ascending aorta replacement in 24 and the Bentall procedure in 26) and simple AVR (n=36). Preoperative characteristics, surgical data, intra- and postoperative allogenic blood transfusion requirement, the postoperative clinical course, and major complications were retrospectively reviewed and compared. Results: The preoperative mean logistic European System for Cardiac Operative Risk Evaluation (%) did not differ between the groups: $11.0{\pm}7.8%$ in the complex AVR group and $12.3{\pm}8.0%$ in the simple AVR group. Although complex AVR required longer cardiopulmonary bypass ($152.4{\pm}52.6$ minutes vs. $109.7{\pm}22.7$ minutes, p=0.001), the quantity of allogenic blood products did not differ ($13.4{\pm}14.7$ units vs. $13.9{\pm}11.2$ units). There was no mortality, mechanical circulatory support, stroke, or renal failure requiring hemodialysis/filtration. No difference was found in the incidence of bleeding (40% vs. 33.3%) which was defined as red blood cell transfusion ${\geq}5$ units, reoperation, or intentional delayed closure. The incidence of mediastinitis (2.0% vs. 0%), ventilator ${\geq}24$ hours (4.0% vs. 2.8%), atrial fibrillation (18.0% vs. 25.0%), mean intensive care unit stay (34.5 hours vs. 38.8 hours), and median hospital stay (8 days vs. 7 days) did not differ, either. Conclusion: AVR combined with additional aortic or root replacement showed an excellent outcome and recovery course equivalent to that after isolated AVR.

Purpose: Postoperative Infectious complications are recognized as major complications that are associated with surgery. Although many studies have focused on the risk factors of postoperative complications, little is known about the risk factors of infectious complications after gastric cancer surgery, and especially after elective gastrectomy. There is now more and more interest in the risk factors of infectious complications in relation to controlling infection and as indicators of qualitatively assessing infectious complications. The aim of this study was to evaluate the risk factors related with infectious complications after performing elective gastrectomy for treating gastric cancer. Materials and Methods: We retrospectively reviewed a total of 788 patients who had undergone elective gastrectomy for gastric cancer between Jan. 2000 and Dec. 2007. The characteristics of the patients were divided according to the patients' factors and the operations' factors. Results: The patients' mean age was 58.9 (range: 24~91) years; 545 were male and 243 were female. The mean duration of the hospital stay was 20.3 days (range: 5~135 days), the mean operation time was 181.3 minutes (range: 65~440 minutes). The total complication rate was 17.1% (n=135) and the complication rate was 38.5% (n=52) among the 135 patients with infectious complications. The infectious complications were surgical site infection (59.7%), Pneumonia (19.3%), intra-abdominal abscess (11.5%), pseudomembranous colitis (5.7%), bacteremia (1.9%) and hepatic abscess (1.9%). On the univariate analysis, the significant risk factors were male gender, blood transfusion, smoking at the time of diagnosis, alcohol drinking, diabetes mellitus and previous cardiovascular disease (P<0.05 for all). On multivariate analysis that used a logistic regression model, the significant independent risk factors were smoking at the time of diagnosis (OR: 2.877. 95% CI: 1.449~5.713), blood transfusion (OR: 3.440, 95% CI: 1.241~9.534), diabetes mellitus (OR: 3.150, 95% CI: 1.518~6.538), and previous cardiovascular disease (OR: 2.784, 95% CI: 1.4731~5.2539). Conclusion: Pre- or post-operative blood transfusion and the patient's medical history such as previous cardiovascular disease, diabetes mellitus, smoking etc. are the risk factors for infectious complications after undergoing elective gastrectomy for gastric cancer. The patients that have these risk factors need to be treated with great care to prevent infectious disease after elective gastrectomy.

Background: Aortopulmonary window (APW) is a very rare congenital heart anomaly, often associated with other cardiac anomalies. It causes a significant systemic to pulmonary artery shunt, which requires early surgical correction. Accurate diagnosis and surgical correction will bring good outcomes. The purpose of this study was to describe our 20-year experience of aortopulmonary window. Material and Method: Between March 1985 and January 2005, 16 patients with APW underwent surgical repair. Mean age at operation was $157.8{\pm}245.3$ ($15.0{\sim}994.0$) days and mean weight was $4.8{\pm}2.5$ ($1.7{\sim}10.7$) kg. Patent ductus arteriosus (8), atrial septal defect (7), interruptedaortic arch (5), ventricular septal defect (4), patent foramen ovate (3), tricuspid valve regurgitation (3), mitral valve regurgitation (2), aortic valve regurgitation (1), coarctation of aorta (1), left superior vena cavae (1), and dextrocardia (1) were associated. Repair methods included 1) division of the APW with primary closure or patch closure of aorta and pulmonary artery primary closure or patch closure (11) and 2) intra-arterial patch closure (3). 3) Division of the window and descending aorta to APW anastomosis (2) in the patients with interrupted aortic arch or coarctation. Result: There was one death. The patient had 2.5 cm long severe tracheal stenosis from carina with tracheal bronchus supplying right upper lobe. The patient died at 5th post operative day due to massive tracheal bleeding. Patients with complex aortopulmonary window had longer intensive care unit and hospital stay and showed more morbidities and higher reoperation rates. 5 patients had reoperations due to left pulmonary artery stenosis (4), right pulmonary artery stenosis (2), and main pulmonary artery stenosis (1). The mean follow-up period was $6.8{\pm}5.6$ (57.0 days$\sim$16.7 years)years and all patients belonged to NYHA class 1. Conclusion: With early and prompt correction of APW, excellent surgical outcome can be expected. However, optimal surgical method needs to be established to decrease the rate of stenosis of pulmonary arteries.
