ABSTRACT
@#Objective To evaluate the short- and mid-term outcomes of sequential anastomosis and simple anastomosis of saphenous vein in off-pump coronary artery bypass grafting. Methods The clinical data of 438 patients who underwent sequential anastomosis of saphenous vein and 165 patients who underwent simple anastomosis of saphenous vein from 2015 to 2018 in Daxing Teaching Hospital were retrospectively analyzed. After propensity score matching, 130 pairs of patients were included in the sequential anastomosis group [78 males and 52 females, aged 60 (52, 68) years] and simple anastomosis group [80 males and 50 females, aged 61 (52, 70) years]. The short- and mid-term clinical outcomes were compared. Results The two propensity score-matched groups had similar baseline clinical data. No significant difference was found between sequential anastomosis and simple anastomosis groups in the in-hospital outcomes, including in-hospital death (1.5% vs. 1.5%, P=1.000), the incidence of complications (4.6% vs. 6.2%, P>0.05), and the mean flow of grafts (30.0±11.8 mL/min vs. 28.0±9.5 mL/min, P=0.597). The operation time of the sequential anastomosis group was shorter than that of the simple anastomosis group (142.5±21.2 min vs. 186.3±27.6 min, P<0.001). The drainage of the sequential anastomosis group was less than that of the simple anastomosis group (204.7±39.6 mL vs. 271.3±48.3 mL, P<0.001). The follow-up time was 12-60 (28.3±8.9) months, during which the mortality of the two groups was not statistically different (3.2% vs. 4.0%, P=0.796). Conclusion The saphenous vein sequential anastomosis of saphenous vein is superior to the simple anastomosis. Sequential anastomosis technique can reduce aortic anastomosis, shorten operation time, and reduce bleeding drainage during off-pump coronary artery bypass grafting. The short- and mid- term clinical effects are satisfactory.
ABSTRACT
@#Objective To evaluate the clinical efficacy of preoperative intra-aortic balloon pump (IABP) insertion in patients with off-pump coronary artery bypass grafting (OPCABG) surgery. Methods The clinical data of 130 patients who underwent OPCABG with IABP from 2015 to 2019 in our hospital were retrospectively analyzed. The patients were divided into two groups, including a group A (preoperative IABP insertion, n=72) and a group B (emergent IABP insertion, n=58). There were 42 males and 30 females in the group A with an average age of 60-72 (65.0±5.2) years. There were 32 males and 26 females in the group B with an average age of 56-73 (62.3±7.6) years. The in-hospital mortality rate and prognosis were compared between the two groups. Results The in-hospital mortality rate in the group A (4.2%) was significantly lower than that in the group B (12.1%, P=0.002). The IABP time (40.8±10.3 min vs. 65.3±15.6 min), mechanical ventilation time (18.7±6.1 min vs. 48.7±10.5 min) and ICU stay time (48.1±7.8 min vs. 90.2±21.3 min) of the group A were shorter than those of the group B (P<0.05). The number of bypass grafts was not significantly different between the two groups (3.6±1.2 vs. 3.8±1.0, P=0.387). Multivariable logistic regression analysis indicated that independent risk factors for in-hospital mortality included age [OR=1.04, 95%CI (1.01, 1.10), P=0.030], female [OR=2.56, 95%CI (1.53, 6.12), P=0.000] and left ventricular end-diastolic diameter [OR=1.05, 95%CI (1.01, 1.13), P=0.030]. Preoperative IABP support was the protective factor [OR=0.17, 95%CI (0.01, 0.78), P=0.005]. Conclusion Patients undergoing OPCABG with preoperative IABP insertion may reduce in-hospital mortality rate and improve outcomes.
ABSTRACT
Objective To explore ways for the supervision of department directors. Methods Job responsibility agreements with department directors were signed and a series of assessment standards were established. Results The methods adopted were standardized, individualized and easy to use. Conclusion Job responsibility agreements with department directors and a standard assessment system are currently effective measures for the supervision of department directors.
