Differential alterations in plasma colony-stimulating factor concentrations after coronary artery bypass graft surgery with extracorporeal circulation

To determine whether colony-stimulating factor (CSF) might participate to the inflammatory response after cardiac surgery, plasma concentrations of granulocyte-CSF (G-CSF), macrophage-CSF (M-CSF) and GM-CSF were measured in 31 patients undergoing coronary artery bypass graft (CABG) surgery with extracorporeal circulation (ECC). Plasma G-CSF and M-CSF concentrations increased after weaning of ECC, reached maximum value at the sixth post-operative hour, and remained elevated at the 24th post-operative hour. In contrast, plasma GM-CSF levels did not change. Plasma M-CSF, G-CSF and GM-CSF values were not different whether patients developed post-operative complications or not. In conclusion, M-CSF and G-CSF are produced after CABG surgery despite the use of high aprotinin doses in hope to abrogate the inflammatory response. G-CSF and M-CSF might play a role in the inflammatory process often observed after CABG surgery.     

"Inflammatory response to colloids compared to crystalloid priming in cardiac surgery patients with cardiopulmonary bypass"

"Cardiac surgery with cardiopulmonary bypass (CPB) induces a systemic inflammatory response syndrome that may contribute to postoperative morbidity and mortality. We investigated the in-flammatory responses to colloids compared to crystalloid priming in cardiac surgery patients with cardiopulmonary bypass. Thirty patients undergoing coronary artery bypass grafting (CABG) preparing for CPB were randomized into Ringer's solution (RS), 10% hydroxyethyl starch (HES) or 25% human albumin (HA) group. Serum concentrations of tumor necrosis factor-α (TNF-α), interleukin-1 β (IL-1β ), interleukin-6 (IL-6) and interleukin-10 (IL-10) were measured before CPB, at the end of CPB and 1, 6 and 12 h after CPB. Serum C-reactive protein (CRP) was determined pre-operatively and then daily for 2 days. Body-weight gain was significantly decreased on the day after surgery in the HES group than in the RS group. Volume priming in CPB for CABG patients using HA or HES preparation had less tendency for intense inflammatory response with lower levels of TNF-α, IL-1 β , IL-6 and higher levels of IL-10 compared to patients treated with RS. HES prime had lower levels of circulating CRP than in patients treated with HA or Ringer prime on the second post-operative day. Our data indicate that volume priming using colloid during CPB in CABG patients might exert beneficial effects on inflammatory responses."     

Predictors and frequency of conduction disturbances after open-heart surgery

Introduction

The risk of developing conduction disturbances after coronary bypass grafting (CABG) or valvular surgery has been well established in previous studies, leading to permanent pacemaker implantation in about 2% to 3% of patients, and in 10% of patients undergoing repeat cardiac surgery. We sought to determine the incidence, features and predictors of conduction disorders in the immediate post-operative period of patients subjected to open-heart surgery, and the need for permanent pacemaker implantation.

Material and Method

We prospectively studied 374 consecutive patients who underwent open-heart surgery in our institution: coronary artery bypass (CABG) (n=128), Mitral valve replacement(MVR)(n=18), aortic valve replacement(AVR) (n=21), MVR and AVR(n=56), repair of ventricular septal defect (VSD) (n=51), repair of tetralogy of Fallot (TOF) (n=57),CABG and valvular surgery (n=6), others (n=37).

Results

Among 374 patients included in our study (mean age 34.46±25.68; 146 males), 192 developed new conduction disorders: symptomatic sinus bradycardia in 8%, atrial fibrillation with slow ventricular response (AF) in 4.5%, first-degree atrioventricular block (AVB)in 6.4%, second-degree AVB in 0.3%, third-degree AVB in 7%, new right bundle branch block (RBBB) in 33%, and new left bundle branch block (LBBB) in 2.1%. In 5.6% patients, a permanent pacemaker was implanted, 47.6% of them underwent valvular surgery. In 44.1% of patients the conduction defects occurred in the first 48 hr. after surgery. In CABG group, 29.7% of patients developed new conduction disturbances; the most common of them was symptomatic sinus bradycardia. After valvular surgery 44.2% of patients developed conduction disturbances, of those the most common was atrial fibrillation with slow ventricular response . After VSD and TOF repair, the most common conduction disturbance was new RBBB. Perioperative myocardial infarction (MI) occurred in 1.9% of patients. The occurrence conduction disturbance was compared with patient age, sex, occurrence of perioperative MI, ejection fraction (EF), postoperative use of ß-adernergic receptor blocking agents and digitalis and type of cardiac surgery. By regression analysis there was a correlation between type of surgery and new conduction defects, being significant for CABG and TOF repair. Only the occurrence of perioperative MI was related to PPM implantation.

Conclusion

Irreversible AVB requiring a PPM is an uncommon complication after open-heart surgery. Peri-operative MI is a risk factor.     

不同麻醉方式对骨科手术患者血流动力学、术后精神状态及认知功能的影响

目的:探讨不同麻醉方式对骨科手术患者血流动力学、术后精神状态及认知功能的影响。方法:选取2016年1月～2018年12月期间我院收治的89例骨科手术患者,根据数字表法将患者随机分为对照组(n=44)和研究组(n=45),对照组给予全身麻醉,研究组给予硬膜外麻醉,比较两组患者围术期指标情况,比较两组患者不同时间点血流动力学、术后精神状态及术后认知功能障碍(POCD)发生率。结果:两组患者术中麻醉时间、术中出血量比较,差异无统计学意义(P0.05);研究组麻醉药物使用量少于对照组,苏醒时间、语言恢复时间短于对照组(P0.05)。两组患者麻醉后术前(T2)时间点平均动脉压(MAP)、心率(HR)均较麻醉前(T1)时间点降低,两组患者手术30 min(T3)、手术结束时(T4)时间点MAP、HR均较T2时间点升高(P0.05),但两组患者T1～T4时间点MAP、HR比较,差异无统计学意义(P0.05)。对照组术后6 h(T5)～术后72 h(T8)时间点、研究组T5～术后24 h(T7)时间点MMSE评分低于T1时间点(P0.05),而研究组T8时间点MMSE评分与T1时间点比较,差异无统计学意义(P0.05);研究组T7、T8时间点MMSE评分高于对照组(P0.05)。研究组T5、术后12 h(T6)时间点POCD发生率均低于对照组(P0.05),两组T7、T8时间点POCD发生率比较,差异无统计学意义(P0.05)。结论:两种麻醉方式均可对骨科手术患者血流动力学、术后精神状态造成一定影响,但硬膜外麻醉对术后精神状态的影响程度相对更轻,同时还可降低POCD发生率,改善围术期部分指标。     

不同干预方式及干预时机对急性非ST 段抬高型心肌梗死伴多支病变的 临床效果研究

Preoperative proteinuria is associated with long-term progression to chronic dialysis and mortality after coronary artery bypass grafting surgery

Aims

Preoperative proteinuria is associated with post-operative acute kidney injury (AKI), but whether it is also associated with increased long- term mortality and end -stage renal disease (ESRD) is unknown.

Methods and Results

We studied 925 consecutive patients undergoing CABG. Demographic and clinical data were collected prospectively, and patients were followed for a median of 4.71 years after surgery. Proteinuria, according to dipstick tests, was defined as mild (trace to 1+) or heavy (2+ to 4+) according to the results of the dipstick test. A total of 276 (29.8%) patients had mild proteinuria before surgery and 119 (12.9%) patients had heavy proteinuria. During the follow-up, the Cox proportional hazards model demonstrated that heavy proteinuria (hazard ratio [HR], 27.17) was an independent predictor of long-term ESRD. There was a progressive increased risk for mild proteinuria ([HR], 1.88) and heavy proteinuria ([HR], 2.28) to predict all–cause mortality compared to no proteinuria. Mild ([HR], 2.57) and heavy proteinuria ([HR], 2.70) exhibited a stepwise increased ratio compared to patients without proteinuria for long–term composite catastrophic outcomes (mortality and ESRD), which were independent of the baseline GFR and postoperative acute kidney injury (AKI).

Conclusion

Our study demonstrated that proteinuria is a powerful independent risk factor of long-term all-cause mortality and ESRD after CABG in addition to preoperative GFR and postoperative AKI. Our study demonstrated that proteinuria should be integrated into clinical risk prediction models for long-term outcomes after CABG. These results provide a high priority for future renal protective strategies and methods for post-operative CABG patients.     

Natriuretic peptides and endothelin-1 in patients undergoing coronary artery bypass grafting

Off-pump coronary artery bypass grafting (CABG) is an alternative to conventional CABG using cardiopulmonary bypass. Off-pump technique reduces the complications of CABG performed with extracorporeal circulatory assistance (Lancey et al. 2000; Mack et al. 2004a,b). The object of this study was to compare peri- and postoperative time courses of vasoactive peptides - atrial natriuretic poptide (ANP), brain natriuretic poptide (BNP) and endothelin-1 (ET-1) in off-pump versus on-pump CABG. 22 patients, who underwent on-pump (group A, n = 11) or off-pump CABG (group B, n = 11) were studied. The peri- and postoperative time courses of plasma ANP and BNP were similar in both groups. A statistically significant difference between ET-1 plasma level 2 h after surgery in the group A and ET-1 plasma level 2 h after surgery in the group B (2.46 + or - 1.14 pg/ml/Ht versus 0.74 + or - 0.09 pg/ml/Ht, p < 0.0001) was found. Different CABG techniques were not associated with significant changes in peri- and postoperative plasma ANP and BNP. By contrast, plasma ET-1 significantly rose in the group A 2 h after surgery, indicating endothelial damage.     

Alterations in plasma angiogenic growth factor concentrations after coronary artery bypass graft surgery: relationships with post-operative complications

To determine whether angiogenic growth factor levels are altered during and after cardiac surgery, plasma concentrations of basic fibroblast growth factor (bFGF), vascular endothelial growth factor (VEGF), epidermal growth factor (EGF) and transforming growth factor beta1 (TGFbeta1) were measured in 32 patients undergoing coronary artery bypass graft (CABG) surgery with extracorporeal circulation (ECC). EGF levels significantly decreased during ECC and remained low until the 24th post-operative hour with no difference between complicated and uncomplicated patients. TGFbeta1 and bFGF concentrations significantly increased at the end of ECC and after cross-clamp release, and returned to pre-operative values at the 6th post-operative hour suggesting that the source of these elevations are the lungs and heart. After cross-clamp release bFGF levels but not TGFbeta1 ones were higher in patients with respiratory impairments. VEGF values increased significantly at the 6th and 24th post-operative hours. At the 24th post-operative hour plasma VEGF levels were higher in patients with cardiovascular and hematological impairments. In conclusion, these results highlight that the angiogenic network is profoundly altered in patients undergoing cardiopulmonary bypass as previously demonstrated for lipidic, cytokine and haematopoietic growth factor ones and identify an association between specific post-CABG complications and systemic release of bFGF and VEGF.
