SUMMARY OBJECTIVE: Inflammation plays a key role in the pathogenesis of postoperative atrial fibrillation after coronary artery bypass graft surgery. In this study, we aimed to investigate the changes in mean platelet volume and platelet values during the spring and autumn seasons in patients who underwent isolated coronary artery bypass graft surgery and the possible effect of these occurrences on postoperative atrial fibrillation. METHODS: Consecutive patients who underwent elective isolated coronary bypass surgery at our clinic in the spring and autumn months, between August 2020 and July 2022, were retrospectively included in this study. Variables were evaluated according to the spring and autumn seasons. Patients who did not develop in-hospital postoperative atrial fibrillation were identified as Group 1, and those who did constituted Group 2. RESULTS: A total of 622 patients were included in the study. The patients were divided into two groups: those who were operated on in the spring (n=277, median age=62 years, male gender ratio=77.3%) and those who were operated on in the autumn (n=345, median age=61 years, male gender ratio=81.4%). There was no statistically significant difference between the patients operated on in both seasons in terms of age, gender, hypertension rates, and the frequency of chronic obstructive pulmonary disease. In multivariate analysis, being over 70 years old (OR: 1.934, 95% confidence interval (CI) 1.489–2.995, p<0.001), having a left ventricular ejection fraction below 30% (OR: 1.550, 95%CI 1.190–2.236, p=0.012), and having chronic obstructive pulmonary disease (OR: 1.663, 95%CI 1.339–2.191, p<0.001) were found to be independent predictors in predicting the development of postoperative atrial fibrillation. CONCLUSION: In this study, we first demonstrated that mean platelet volume and platelet mass index values were higher in patients in the autumn months. Additionally, for the first time in the literature, we showed that there is a significant relationship between platelet mass index value and the development of postoperative atrial fibrillation in patients who underwent isolated coronary artery bypass graft.

ABSTRACT Postoperative pain after cardiac surgery plays an important role in the patient’s recovery process. In particular, pain at the chest tube site can negatively affect the comfort and recovery of these patients. Effective pain control minimizes the risk of many complications. Oral and intravenous analgesics, epidural anesthesia, paravertebral block, and intercostal nerve blockade are used in chest tube pain control. We routinely use the surgical cryoablation method in the presence of atrial fibrillation in the preoperative period of cardiac surgery in our clinic. Here we aimed to describe our method of using the cryoablation catheter for intercostal nerve blockade. patients patient s process particular complications analgesics anesthesia block clinic

SUMMARY OBJECTIVE: After cardiac surgery, acute kidney injury is observed at a rate of 5–30%, and the second most common cause of acute kidney injury in intensive care units is cardiac surgery. In this study, we aimed to investigate the effect of del Nido cardioplegia solution use on postoperative acute kidney injury development in patients who underwent coronary artery bypass grafting operation with cardiopulmonary bypass. METHODS: Consecutive patients who underwent an elective coronary artery bypass grafting operation with cardiopulmonary bypass in our clinic between March 15, 2019, and March 15, 2020, were included in the study retrospectively. The patients were divided into two groups as those who received del Nido cardioplegia solution (Group 1) and blood cardioplegia (Group 2), and factors affecting the development of renal failure were examined. RESULTS: A total of 350 consecutive patients were included in the study. There were 156 patients in the del Nido cardioplegia group and 194 patients in the blood cardioplegia group. Among the patient group, 74 (21.1%) patients developed acute kidney injury. The total acute kidney injury development rate was significantly higher in Group 2 (p=0.018). In multivariate logistic regression analysis, advanced age (OR 1.128; 95%CI 1.044–1.217; p=0.042), increased blood product use (OR 1.318; 95%CI 1.154–1.998; p=0.019), preoperative creatinine elevation (OR 2.434; 95%CI 1.655–4.639; p=0.005), and increased cardioplegia volume (OR 1.254; 95%CI 1.109–2.980; p=0.009) were independent predictors of acute kidney injury. CONCLUSION: With this study, we showed that the use of del Nido cardioplegia solution can reduce the incidence of acute kidney injury.

Abstract Objective To evaluate whether hyperbaric oxygen (HBO) treatment has a favorable effect on implant osseointegration in diabetic rabbits. Material and Methods An experimental diabetes model was induced in 32 New Zealand rabbits through IV injection of alloxan. After the state of diabetes had been confirmed, one dental implant was placed in the metaphysical region of each animal’s tibia. After the implants’ placements, the animals were divided into two groups. Half of the animals underwent HBO treatment, while the other group did not receive HBO treatment and served as the control group. The animals were euthanized at the 4th and 8th weeks. The osseointegration of the implants were compared by histomorphometry and resonance frequency analysis (RFA). Results The Bone Implant Contact (BIC) values were significantly higher in the HBO group than in the control group at the 4th week. There was no difference in the BIC values between the groups at the 8th week. There was no significant difference in the RFA scores between the groups both at the 4th and 8th weeks after the operation. Conclusion Histomorphometry findings suggest that HBO has positive effect on implant osseointegration in the early healing period in diabetic rabbits. However, implant stability is not affected by HBO treatment.

Esophageal or gastric injuries secondary to caustic substance ingestion is still an important issue in developing countries. Its clinical spectrum can vary from absence of mucosal injury to complications such as severe burns, strictures and perforation. Physical examination and first endoscopic evaluation are very important in the diagnosis. The objective of this study is to present 154 children who were undergone upper gastrointestinal endoscopy because of caustic substance ingestion including descaler, degreaser, unlabeled bleach, drain opener, surface cleaner, dishwasher rinse aid, hydrochloric acid. Sixty-nine children had positive oropharyngeal findings. Sixty-three children were found to have burns in the first endoscopic examination and forty of these burns were severe burn. In the follow-up, twenty children developed strictures that were undergone dilatation program. Fourteen children in the dilatation program had successful dilatation and intralesional steroid injection. However three children had undergone colonic interposition and three undergone laparoscopic gastroduodenostomy and gastrojejunostomy.

Las lesiones esofágicas o gástricas secundarias a la ingesta de sustancias cáusticas siguen siendo un problema importante en los países en vías de desarrollo. El espectro clínico puede variar desde la ausencia de una lesión en la mucosa hasta complicaciones tales como quemaduras graves, estenosis y perforación. El examen físico y la evaluación endoscópica inicial son sumamente importantes para el diagnóstico. El objetivo de este estudio es presentar los casos de 154 niños sometidos a una endoscopía digestiva alta debido a la ingesta de sustancias cáusticas, entre otras, desincrustante químico, desengrasante, lavandina no rotulada, limpiador de tuberías de desagüe, limpiador de superficies, abrillantador de vajilla y ácido clorhídrico. Se observaron signos orofaríngeos positivos en 69 niños. Con la endoscopía inicial, se hallaron quemaduras en 63 niños; en 40, las quemaduras eran graves. Durante el seguimiento, se produjo estenosis en 20 niños, que fueron incluidos en el programa de dilatación. Entre ellos, fue posible dilatar e inyectar corticoides intralesionales satisfactoriamente a 14 niños. Sin embargo, tres niños fueron sometidos a una interposición de colon, y otros tres, a una gastroduodenostomía y gastroyeyunostomía.
