Introduction: In the perioperative period, regional analgesia techniques may play an increasingly important role in "Enhanced Recovery After Surgery (ERAS)" programs, as they can facilitate recovery. We hypothesized that Erector Spinae Plane (ESP) block could improve regional perfusion, thereby limiting blood lactate increase. Therefore, we aimed to evaluate the effect of ESP block on intraoperative blood lactate levels in patients scheduled for elective on-pump cardiac surgery with ERAS protocol. Methods: A total of 68 adult patients scheduled for on-pump cardiac surgery were included. All patients were randomized to the ESP group and the non-ESP group. Blood lactate analyses were performed at intraoperative five-time points. C-Reactive protein (CRP) values were also measured. Results: Blood lactate values were significantly lower in the ESP group than in the Non-ESP group, at the end of CPB [1.78 (1.23–2.78) mmol L−1 to 2.63 (1.70–3.12) mmol L−1] and during the sternal closure period [1.78 (1.27–2.42) mmol L−1 to 2.40 (2.14–2.80) mmol L−1] (p = 0.039, p = 0.009). In addition, CRP values were significantly lower in the ESP group in the postoperative period [0.048 (0.036–0.105) g L−1 to 0.090 (0.049–0.154) g L−1] (p = 0.035). Conclusions: This study showed that preoperative bilateral single-shot ESP block significantly reduces intraoperative final blood lactate and postoperative CRP values. We consider that these results are related to the attenuation of intraoperative hypoperfusion and the alleviation of surgery-related postoperative inflammation. ERAS programs aim to achieve the rapid recovery of patients, a decrease in inflammation, and high-quality analgesia with less opioid consumption. Therefore, our results also prove that it is easier to reach the primary goals of ERAS programs with the application of ESP block in cardiac surgery. [ABSTRACT FROM AUTHOR]

Introduction: Cold agglutinin disease (CAD) is a rare autoimmune disorder characterized by destruction (hemolysis) of erythrocytes. In CAD, autoantibodies that cause agglutination at temperature of optimum +3-+4 ℃ degree cause symptoms. It is known that CAD often occurs after viral infections. Also, it has been reported in case reports that COVID-19 disease can cause CAD. Case Report: 46-year-old male patient with a history of diabetes mellitus and hypertension presented to outpatient clinic in our department to have CABG surgery. He recovered from COVID-19 disease 1.5 months ago. Cardiopulmonary bypass was initiated and the cross-clamp was placed and antegrade Delnido cardioplegia solution was started to be given at +4 ℃. It was observed that the cardioplegia line was agglutinated. On the other hand, it was seen that the autologous blood taken by the anesthesiologist was also agglutinated and formed air bubbles and became unusable. X-clamp was removed and the heart rhythm recovered. The patient was consulted to hematology during postoperative intensive care follow-ups. The cold agglutinin test performed at of +4 ℃ was reported as positive. In this case, we associated the CAD with covid-19 for three main reasons. First one, the patient's complaints about CAD started after COVID-19 disease. Secondly, in the national health archive, the patient's pre-COVID-19 blood tests were completely normal but it was seen that LDH increased and RBC-HCT incompatibility started after COVID-19. As the third, when we search the literature, we have seen the COVID-19 related CAD in many case reports published by hematologists. Conclusion: With the rare cold agglutinin disease, it seems that we will encounter it more often after the COVID-19 pandemic. Except for deep hypothermia, the most important problem is seen during cardioplegia administration. Therefore, non-blood cardioplegia can be lifesaving. [ABSTRACT FROM AUTHOR]

Background: Carotid endarterectomy (CEA) is the treatment of choice for patients with symptomatic and asymptomatic high-grade carotid stenosis. In literature there are papers advocating patch plasty for better results. But there is controversy about which patch material is optimal for use. This study compared rate of neurologic events, and perioperative death in patients undergoing CEA with primary closure versus patch closure., Methods: We compared patch angioplasty to primary closure between August 2008 and December 2012 in 57 operations. Patients grouped according to their closure technique. Early (30-day) stroke and mortality rate were evaluated. Mean age of patients was 67.79±10.19 (range 41-85 years). 15 (26.31%) of patients were female., Results: Primary closure was used in 13 operations, and patch angioplasty was used in 44 (saphenous vein: 5, Dacron: 23, Fabric: 5, Carotid: 11). There were no significant differences among groups' baseline characteristics. Primary closure was associated with significantly more postoperative major stroke compared with patch used closure (P=0.05). None of preoperative variables were associated with postoperative stroke., Conclusions: On the basis of our results, avoiding primary closure for CEA is defendable. But choice of patch material needs large trials to conclude.
