AbstractDuctus arteriosus is an essential component of fetal circulation. Due to occurring changes in the cardiopulmonary system physiology after birth, ductus arteriosus closes. Patent ductus arteriosus can be closed by medical or invasive (percutaneous or surgical) treatment methods. Percutaneous or surgical closure of patent ductus arteriosus can be performed for the cases that medical closure failed. Surgical treatment is often preferred method for closure of patent ductus arteriosus in the neonatal period. The most common surgical complications are pneumothorax, recurrent laryngeal nerve injury, bleeding, and recanalisation. A very rare surgical complication is left pulmonary artery ligation that has been presented in a few cases in the literature. Echocardiography control should be performed in the early post-operative period, especially in patients with clinical suspicion. If reoperation is required, it should never be delayed. We report a newborn patient whose left pulmonary artery ligated accidentally during patent ductus arteriosus closure surgery and surgical correction of this complication at the early post-operative period.

Fluctuations are freguently seen in the anticoagulant status of patients in the immediate post operative period following prosthetic heart valve replacement. These patients are at high risk of haemorrhage or thromboembolism. We have used a pharmokinetic model of warfarin metabolism to develop a computer programme to predict the maintenance dose of warfarin from early prothrombin activity determinations. This will enable controlled anticoagulation to be achieved. The expression for warfarin kinetics employs 4 constants determined by the residual sum of the sguares, which are used immediately to redefine dosage predictions. In a pilot study data obtained from 16 patients post operation 3, 5 and 7 days after commencing treatment, has been used to predict the reguired maintenance dose at 21 days. These predicted doses were then compared with the maintenance dose achieved by clinical practice. The programme was told to optimise its dose to achieve a PT ratio of 3 whereas clinically the ratio was allowed to vary in the therapeutic range of 2 to 4. Predicted doses at 21 days are shown.in the table:Correlation between predicted and clinical maintenance doses after 3 and 5 days treatment was poor but had improved significantly by 7 days, despite similar levels of prothrombin activity. Predicted prothrombin activity never exceeded the upper limit of the therapeutic range, and the predicted dose can be uprated on addition of further data within 2 minutes.After 7 days computer predicted warfarin dose has produced a good correlation with the clinical maintenance dose (the doses of only 3 patients varying by more than 1 mg/day). The significant fluctuations seen in the prothrombin ratio during clinical dosage were not observed with computer dosing and we now feel it is safe to use this programme to anticoagulate patients post operatively.

Hip And Knee Arthroplasty

Total hip and knee arthroplasty are common major orthopedic operations being performed on an increasing number of patients. Many patients undergoing total joint arthroplasty (TJA) are on chronic antithrombotic agents due to other medical conditions, such as atrial fibrillation or acute coronary syndrome. Given the risk of bleeding associated with TJAs, as well as the risk of thromboembolic events in the post-operative period, the management of chronic antithrombotic agents perioperatively is critical to achieving successful outcomes in arthroplasty. In this review, we provide a concise overview of society guidelines regarding the perioperative management of chronic antithrombotic agents in the setting of elective TJAs and summarize the recent literature that may inform future guidelines. Ultimately, antithrombotic regimen management should be patient-specific, in consultation with cardiology, internal medicine, hematology, and other physicians who play an essential role in perioperative care.

Introduction and objective: Nephrectomy leads to derangement of renal function and various adaptive changes by the remaining kidney over a period of time. This study is performed to evaluate the amount of derangement of renal function in donor and radical nephrectomy, how much the remaining kidney adapts over a period of time and the time taken for stabilisation of renal function. Method: A total of 60 patients who underwent nephrectomy (Radical/Donor) were followed up for 12 months with serial estimation of renal function and was compared with preoperative renal function. Data was analysed with statistical analysis. Result: Patients who underwent radical nephrectomy had 37% initial decline in renal function which was later stabilised at 19% lower than baseline value. Patient who underwent donor nephrectomy had initially 39% decline in renal function which was later stabilised at 24% lower than normal. Conclusion: Removal of functional renal tissue led to reduction of renal function. This decline is more evident in the initial post-operative period and then begin to stabilise over months. The greater is the amount of normal tissue removed, the greater is the reduction of renal function and more time it will take to stabilise, increasing overall morbidity of the patient. This study suggests that even patients with normal GFRs should be followed up postoperatively to determine their ultimate renal functional outcomes.

Hba1c Levels

Background Diabetes is associated with higher mortality and worse post-operative outcomes in patients undergoing coronary artery bypass grafting and HbA1c levels have consistently been reported to be associated with adverse post-operative outcomes. However, the role of HbA1c still remains unclear with regards to the occurrence of atrial fibrillation. Method Data for the patients undergoing off-pump coronary artery bypass grafting was analysed in a retrospective fashion. Patients were divided into–those with HbA1c < 6.5% and those with HbA1c ≥ 6.5% and the incidence of atrial fibrillation observed in these two groups. We also compared patient who developed atrial fibrillation in the post-operative period and compared them with those who did not. Results Of the 5259 patients included in the study HbA1c was <6.5 in 2808 (53.4%) patients and was ≥6.5 in 2451 (46.6%) patients; 623 (11.8%) patients in our study developed atrial fibrillation. Onset of atrial fibrillation in the post-operative period was seen most commonly 235 (38.3%) on between 24 and 48 h after the operation with more than half of them 338 (54.2%) occurring within the first 48 h. On multivariate analysis, HbA1c was not a risk factor for atrial fibrillation (odd’s ratio 1.144, 95% confidence interval 0.967–1.354). Only increased age (odd’s ratio 1.08; 95% confidence interval 1.069–1.091); EuroSCORE (odd’s ratio 1.073; 95% confidence interval 1.048–1.099); history of recent MI (odd’s ratio 0.768; 95% confidence interval 0.606–0.971) and peripheral vascular disease (odd’s ratio 1.667; 95% confidence interval 1.091–2.517) were found to be independently associated with increased risk of atrial fibrillation in the post-operative period. Conclusions After adjusting for confounders HbA1c levels do not independently predict risk of atrial fibrillation after off-pump coronary artery bypass grafting.

Abstract Purpose To evaluate the available tibial fracture non-union prediction scores and to analyse their strengths, weaknesses, and limitations. Methods The first part consisted of a systematic method of locating the currently available clinico-radiological non-union prediction scores. The second part of the investigation consisted of comparing the validity of the non-union prediction scores in 15 patients with tibial shaft fractures randomly selected from a Level I trauma centre prospectively collected database who were treated with intramedullary nailing. Results Four scoring systems identified: The Leeds-Genoa Non-Union Index (LEG-NUI), the Non-Union Determination Score (NURD), the FRACTING score, and the Tibial Fracture Healing Score (TFHS). Patients demographics: Non-union group: five male patients, mean age 36.4 years (18–50); Union group: ten patients (8 males) with mean age 39.8 years (20–66). The following score thresholds were used to calculate positive and negative predictive values for non-union: FRACTING score ≥ 7 at the immediate post-operative period, LEG-NUI score ≥ 5 within 12 weeks, NURD score ≥ 9 at the immediate post-operative period, and TFHS < 3 at 12 weeks. For the FRACTING, LEG-NUI and NURD scores, the positive predictive values for the development of non-union were 80, 100, 40% respectively, whereas the negative predictive values were 60, 90 and 90%. The TFHS could not be retrospectively calculated for robust accuracy. Conclusion The LEG-NUI had the best combination of positive and negative predictive values for early identification of non-union. Based on this study, all currently available scores have inherent strengths and limitations. Several recommendations to improve future score designs are outlined herein to better tackle this devastating, and yet, unsolved problem.
