Pain after cardiac surgery is always an obsession of patients and a top concern of anesthesiologists. Experimental subjects challenged by acute pain and patients in chronic pain experience impairments in attention control, working memory, mental flexibility, problem solving, and information processing speed. The two most commonly used analgesia methods are patient-controlled analgesia (PCA) and erector spinea plane block (ESP). Our study aimed to compare the analgesic effect of ESP with PCA in patients after cardiac surgery using extracorporeal circulation and evaluate the disavantages of these two pain relief techniques. Subject and methods: This study was a randomized controlled intervention study of adult patients who underwent open-heart surgery patients with extracorporeal circulation from May 2020 to September 2021 in the Department of Anesthesiology and Intensive Care Unit - Hanoi Heart Hospital. Results: Two hundred and four (204) consecutive patients were collected, included 108 patients in the ESP group and 96 patients in the PCA group. The mean intraoperative fentanyl amount in the ESP group (0.57±0.50 mg) was lower than in the PCA group (1.00±0.00 mg) (p<0.05). The average VAS score when the patient was lying still and taking deep breaths at the time of assessment in both groups was below 3 (corresponding to low pain level) (p>0.05). The mean morphin consumption 24 hours after surgery was significantly lower in the ESP group (0,23±0,12 mg) than in the PCA group (17,92±3,32 mg) (p<0.05). The mean time after surgery in the ESP group (3.80±1.02 hours) and the PCA group (5.21±1.10 hours) had a clear difference between p<0.05. The mean time of extubation in the ESP group (8.06±1.60 hours) was statistically significantly lower than in the PCA group (8.83±1.43 hours) (p<0.05). The rate of nausea in the ESP group (20.98%) was lower than in the PCA group (58.33%) (p<0.05). Conclusion: Both methods had good analgesic effect with an average VAS score ≤ 3. The ESP group had a lower mean postoperative morphine consumption, a higher patient satisfaction level, and a lower rate of nausea, vomiting, and slow breathing statistically significant less than the PCA group.

The Mean

SummaryA prospective study in 13 patients undergoing open-heart surgery with extracorporeal circulation revealed a marked decrease of the mean one-stage prothrombin time activity from 88% to 54% (p <0.005) but lesser decreases of factors I, II, V, VII and X. This apparent discrepancy was due to the appearance of an inhibitor of the extrinsic coagulation system, termed PEC (Protein after Extracorporeal Circulation). The mean plasma PEC level rose from 0.05 U/ml pre-surgery to 0.65 U/ml post-surgery (p <0.0005), and was accompanied by the appearance of additional proteins as evidenced by disc polyacrylamide gel electrophoresis of plasma fractions (p <0.0005). The observed increases of PEC, appearance of abnormal protein bands and concomitant increases of LDH and SGOT suggest that the release of an inhibitor of the coagulation system (similar or identical to PIVKA) may be due to hypoxic liver damage during extracorporeal circulation.

Background: Acute kidney injury (AKI) is one of the most serious complications during the postoperative period of cardiac surgery. Multiple variables predict the ARF after cardiac surgery. Objective of this study was to evaluate the significance of pre and peri-operative variables which may help in predicting the chances of developing ARF after cardiac surgery.Methods: This study was an observational, prospective study conducted among patients who were scheduled to undergo open heart surgery under cardiopulmonary bypass.Results: In total, 50 patients who underwent open-heart surgery, ARF was seen in 5 patients, with the incidence rate of 10%. Acute renal failure was present in one patient with ejection fraction <35, 2 patients had ejection fraction between 35 to 50 and 2 patients with ejection fraction >50. It was seen in 4 patients with 1-2 hrs of cardiopulmonary bypass and in 1 patient with >2 hrs of cardiopulmonary bypass. ARF was also seen in 4 patients with hematocrit between 22-26% and in 1 patient with >26%.Conclusions: The study provided a clinical variable score that can predict ARF after open-heart surgery. The score enhances the accuracy of prediction by accounting for the effect of all major risk factors of ARF.

The Impact

Objective: Thromboelastography (TEG) is a diagnostic modality that gives information about coagulation. Despite all blood-preserving precautions in open heart surgery there are blood losses and the use of blood and blood products becomes inevitable. TEG is mostly not available in every center and habits, trends and clinical experience in blood use create the possibility of causing unnecessary use of blood and blood products. In this study, it was aimed to determine the effect of the use of thromboelastography on the use of blood and blood products in cardiac surgery. Methods: Two hundred patients between 18-70 years old who underwent open heart surgery were included in the study. After the cardiopulmonary bypass (CPB), the cases were confirmed to have an Activated Clotting Time (ACT) value in the range of 120-150 sec after protamine administration. In 100 patients in the TEG group, the coagulation status was evaluated with TEG and it was decided how to apply blood and blood product use. Blood and blood product use was applied to 100 patients in the control group based on clinical experience and foresight. The total amount of blood and blood product used, fluid balance, need for inotropics, mechanical ventilator time, complications, duration of intensive care and discharge times were recorded. Results: Use of Fresh Frozen Plasma (FFP) at the after CPB in the TEG group was statistically significantly lower than that of the control group FFP (p<0.05). Postoperative FFP and postoperative platelet use in the study group were statistically significantly lower than in the postoperative FFP and postoperative platelet values of the control group (p <0.05). Conclusion: The use of thromboelastography is a very useful monitoring in terms of reducing FFP use after CPB and reducing FFP and platelet usage in the postoperative period. In this way, the unnecessary use of blood and blood products can be prevented.

The Relationship

Systemic inflammatory response was first determined in 1980 and cardiac surgeons turned to it in 1996. At present, there are a lot of publications on this issue, however, the extent of operation and duration of CPB are considered in clinical practice as crucial indicators of severity of patient's condition following cardiac surgery. In our study we tried to look at this problem from a different perspective and draw a parallel between the severity of patient's condition resulting from operational trauma and CPB. We included 48 patients who under-went cardiac surgery under CPB. Plasma levels of procalcitonin (PCT), lactate and interleukin-6 were investigated before the operation, after CPB and at 24 hours. Also revealed was the relationship between the plasma levels of IL-6, lactate and PCT (r = 0.53; p = 0.000 in both cases). The level of PCT at the 3rd stage was found to relate to the duration of CPB (r = 0.4; p = 0.005), ALV (r = 0.44; p = 0.001) and length of stay at ICU (r = 0.53; p = 0.000). We didn't manage to find any relationship between the length of stay at ICU and the duration of CPB. Correlation between the PCT plasma level and the duration of intensive care indicates the importance of dynamics of the given biomarker for early prediction of follow-up course after open-heart surgery.

Objective: Intraoperative CARTO Mapping for Atrial Fibrillation ablation in cardiac surgery. Background: Surgical ablation of Atrial Fibrillation is usually performed without mapping. The study aims to determine if intraoperative CARTO can be useful to guide the ablating procedure. Methods and Findings: Fourteen patients with symptomatic and drug-refractory concomitant AF were operated on in 2003 and 2004. CARTO mapping was performed before and after surgical bipolar radio-frequency ablation. Application of energy was repeated when residual electrical activity was detected at the pulmonary veins-atrial junction. Pacing wires were applied on right and left pulmonary veins distally to the ablation line to confirm the exit block. The mapping protocol was completed in 12 patients. Acute left atrium-pulmonary vein isolation was achieved after single or double energy application in 2/12 (16.6%) and 9/12 (75%) patients, respectively. The mean duration of the mapping and ablation procedure was 67 minutes. At discharge, PV isolation persisted in 10 patients: exit block was confirmed by the absence of pacing through the pulmonary veins electrodes. After a mean follows up of 181 months, no further recurrent AF events were registered in 9/12 (69.2%) patients. Conclusions: CARTO system is useful during open-heart surgery to guide the ablating strategy.
