The OBJECTIVE of the study was to compare the results of using the longitudinal – cross-linking method of sternum osteosynthesis with other methods (single wire stitches, 8-shaped wire stitches) for cardiosurgery patients.METHODS AND MATERIALS. The study included 3,150 patients, which were operated on in Samara cardiology dispensary named after V. P. Poliakov from 2012 to 2018. Patients were divided into 2 groups. Group 1 (1397 patients, operated on from 2012 to 2014) used single wire stitches or 8-shaped wire stitches for sternum osteosynthesis. Group 2 (1753 patients, operated from 2015 to 2018) used the longitudinal -cross-linking method of sternum osteosynthesis. The incidence of instability of the sternum without infection, superficial postoperative wound infection, deep sternal infection and hospital mortality were evaluated.RESULTS. Groups (1–68 % of men, average age (59.4±9,9) years; 2–68 % of men, average age 62.3±8.5) were significantly different in obesity patients (25.6 & 29.3 %, p=0.02), amount of smokers (50.5 & 64.2 %, p<0.001) and amount of urgent cases (3 & 10 %, p<0.001). The incidence of sternal instability without infection was less in group 2 (0.64 & 0.29 %; OR, 2.29; 95 % CI, 0.76 to 6.8; p=0.1). The amount of deep sternal infection was significant less in group 2 (1.6 & 0.6 %; OR, 2.53; 95 % CI, 1.2 to 5.2; p=0.009). The hospital mortality was 3.9 % in group 1 and 2.96 % in group 2 (OR, 1.34; 95 % CI, 0.9 to 1.9; p=0.1).CONCLUSION. The longitudinal-cross-linking method of sternum osteosynthesis is the available method that can significantly reduce the incidence of deep sternal infection in cardiosurgery.

Relevanc. Surgical Site Infection (SSI) after open heart surgery is a significant problem in clinical, social, and economic aspect which causes the need to identification of the preferred procedures for successful prevention of the SSI.Objectives. To determine risk of the SSI in cardiac surgery depending on complexity of intervention, using of cardiopulmonary bypass (CBP) and use of both internal mammary arteries (IMA).Methods. Prospective observations study from 2010 to 2019 in cardiac surgery department of the Ural Institute of Cardiology, where in total 4993 open heart surgery procedures were consecutively performed. All SSI cases were recorded up to 90 days after surgery. The analysis was performed to identify risk of cardiopulmonary bypass (CPB), bilateral IMA grafting and combined procedures on the risk of the postoperative wound infection.Results. During the investigation period, total 220 cases of the SSI (4,5%) have been registered of the 4993 patients undergoing open heart surgery. It included 42 cases of deep sternal infection (0,9%) and 178 cases of superficial infection (3,6%). The main pathogen identified was Staphylococcus epidermidis (56,4%). During the hospital period, 151 cases (66,5%) of SSI have been detected, with the median time to detection of the complication 6 days. The relative mortality risk in deep sternal infection group was 4,4 times higher than in the group without SSI (HR 4,6, 95 % CI 1,5-13,9, p=0,003624). CABG increases the relative risk of SSI in compare with non-CABG procedures (OR 3,086169; 95%CI 1,281 – 7,437), while the complexity of the operation (combined versus isolated interventions) does not significantly increase the risk (OR 0.972283; 95% CI: 0.696 - 1.359). The incidence of SSI in the group of in situ BIMA grafting was 8.8%, significantly increasing the likelihood of the SSI in compare to those with SIMA (OR 2.167983, 95% CI 1.463 - 3.212; p =0,000057). CBP significantly increases the risk of postoperative wound infections (OR 1.523890, 95% CI 1.149 - 2.022, p = 0.001742).Conclusions. Refusal of cardiopulmonary bypass, simultaneous procedures and bilateral coronary artery bypass does not allow completely to avoid postoperative wound infections. Nevertheless, the technical features of the preparations and use of grafts, including skeletonization, prevention of coagulation and the preference for sequential composite CABG, can reduce the risk associated with the type of the open heart surgery.

Background: Complex cardiac surgery in neonates and small-weight babies is a challenge. In addition to the surgical expertise and skill required, accurate diagnosis, management of anesthesia, perfusion, and postoperative critical care are equally challenging. Methods: We have analyzed the data of 4 different examples of complex cardiac surgery in neonates and small-weight babies from February 2012 to July 2019 in our unit. The first group included 118 cases of arterial switch operations for transposition of great arteries with and without ventricular septal defect (group 1). The second group included 52 patients of aortic arch repair from midline using selective cerebral perfusion avoiding total circulatory arrest (group 2). The third group included 75 patients of repair of coarctation of aorta from thoracotomy using the modified end-to-side technique (group 3). The fourth group included 40 neonates and small-weight babies who underwent repair of total anomalous pulmonary venous connection (group 4). Results: In group 1, there was hospital mortality in 6 babies. In group 2, there was no hospital mortality. In group 3, there was 1 hospital death; in group 4, there were 5 hospital deaths. The major contributing cause of death was respiratory or blood-borne infection causing respiratory issues leading to prolonged ventilation. Left diaphragm palsy contributed to morbidity and eventual death in 2 babies. Only 2 patients required tracheostomy to wean off the ventilator. Conclusions: In the present day, it is possible to achieve satisfactory results with acceptable mortality in neonatal cardiac surgery. Morbidity associated with very early repair in neonatal age, low weight, and infection-related issues is manageable with good outcomes.

Abstract. Summary: Background: This pilot study was set up to examine the effects of a continuous postoperative wound infusion system with a local anaesthetic on perioperative pain and the consumption of analgesics. Patients and methods: We included 42 patients in this prospective observational pilot study. Patients were divided into two groups. One group was treated in accordance with the WHO standard pain management protocol and in addition to that received a continuous local wound infusion treatment (Group 1). Group 2 was treated with analgesics in accordance with the WHO standard pain management protocol, exclusively. Results: The study demonstrated a significantly reduced postoperative VAS score for stump pain in Group 1 for the first 5 days. Furthermore, the intake of opiates was significantly reduced in Group 1 (day 1, Group 1: 42.1 vs. Group 2: 73.5, p = 0.010; day 2, Group 1: 27.7 vs. Group 2: 52.5, p = 0.012; day 3, Group 1: 23.9 vs. Group 2: 53.5, p = 0.002; day 4, Group 1: 15.7 vs. Group 2: 48.3, p = 0.003; day 5, Group 1 13.3 vs. Group 2: 49.9, p = 0.001). There were no significant differences between the two groups, neither in phantom pain intensity at discharge nor postoperative complications and death. Conclusions: Continuous postoperative wound infusion with a local anaesthetic in combination with a standard pain management protocol can reduce both stump pain and opiate intake in patients who have undergone transfemoral amputation. Phantom pain was not significantly affected.

Abstract Background Managing elderly patients with infection or malfunction deriving from a cardiac implantable electronic device (CIED) may be challenging. The aim of this study was to evaluate safety and efficacy of mechanical transvenous lead extraction (TLE) in elderly patients. Methods Patients who had undergone TLE in single tertiary referral center were divided in two groups (Group 1: ≥80 years; group 2:&lt;80 years) and their acute and chronic outcomes were compared. All patients were treated with manual traction or mechanical dilatation. Results Our analysis included 1316 patients (group 1: 202, group 2: 1114 patients), with a total of 2513 leads extracted. Group 1 presented more comorbidities and more pacemakers, whereas the dwelling time of the oldest lead was similar, irrespectively of patient's age. In group 1 the radiological success rate for lead was higher (99.0% vs 95.9%; P&lt;0.001) and the fluoroscopy time lower (13.0 vs 15.0 minutes; P=0.04) than in group 2. Clinical success was reached in 1273 patients (96.7%), without significant differences between groups (group 1: 98.0% vs group 2: 96.4%; P=0.36). Major complications occurred in 10 patients (0.7%) without significative differences between patients with more or less than 80 years (group 1: 1.5% vs group 2: 0.6%; P=0.24). In the elderly group no in-hospital mortality occurred (0.0% vs 0.5%; P=0.42). Conclusions Mechanical TLE in elderly patients is a safe and effective procedure. In the over-80s, a comparable incidence of major complications with younger patients was observed, with at least a similar efficacy of the procedure and no procedural-related deaths.

Background: The use of antibiotic prophylaxis during Lichtenstein inguinal hernia surgery is controversial, and no definitive guidelines are available in literature. Objective: To determine effects of prophylactic antibiotics in reducing the frequency of postoperative wound infection in Lichtenstein hernia repair. Study Design: Case control study. Setting: Surgical Unit II, Allied Hospital, Faisalabad. Duration: One year, between January 2007 and December 2007. Methods: Patients undergoing unilateral, primary inguinal hernia repairelectively with the Lichtenstein technique using polypropylene mesh were randomized to receive 1.0 g intravenous Cefazolin before the incision or an equal volume of placebo. Wound infection was defined according to the criteria of Centers for Disease Control and recorded. Results were assessed using chi-square test. Results: 100 patients were included in the study. Minimum age of patients in this study was 20 and maximum 75 years with a mean of 44.06 in group A and 44.84 in group B. The total number of wound infections was 7 (7%); 2 (4%) in the antibiotic prophylaxis group and 5 (10%) in the placebo group. Statistical analysis showed no significant difference in the number of wound infections in both groups (p value=0.240). Conclusions: We conclude that in Lichtenstein inguinal hernia repair routine use of prophylactic antibiotics is not needed, as it does not significantly reduce the postoperative wound infection rates.
