Objective To explore the hemodynamic assessment after radical surgery in children with tetralogy of Fallot (TOF) by both echocardiography and Mostcare monitor. Methods Clinical data of 63 children with TOF who underwent radical surgery in our hospital from February 2016 to June 2018 were retrospectively analyzed, including 34 males and 29 females, aged 6-24 (9.82±5.77) months. There were 19 patients undergoing transannular patch reconstruction of the right ventricular outflow tract (a transannular patch group) while 44 patients retained the pulmonary valve annulus (a non-transannular patch group) . The echocardiography and Mostcare monitor parameters were recorded and brain natriuretic peptide was tested at the time points of 0, 8, 12, 24 and 48 hours after operation (T 0, T 1, T 2, T 4) to analyze their correlations and the change trend at different time points after radical surgery. Results The left ventricular ejection fraction at T 1 (43.49%±3.82%) was lower than that at T 0 (48.29%±4.55%), T 2 (45.83%±3.69%), T 3 (53.76%±4.43%) and T 4 (60.54%±3.23%, P<0.05). The cardiac index at T 1 (1.85±0.35 L·min−1·m−2) was lower than that at T 0 (2.11±0.38 L·min−1·m−2), T 2 (2.07±0.36 L·min−1·m−2), T 3 (2.42±0.37 L·min−1·m−2) and T 4 (2.82±0.42 L·min−1·m−2, P<0.05). The cardiac circulation efficiency at T1 (0.19±0.05) was lower than that at T 0 (0.22±0.06), T 2 (0.22±0.05), T 3 (0.28±0.06) and T 4 (0.34±0.06, P<0.05). The right ventricular two-chambers view fraction area change at T 1 (23.17%±3.11%) was lower than that at T 0 (25.81%±3.74%), T 2 (25.38%±3.43%), T 3 (30.60%±4.50%) and T 4 (36.94%±5.85%, P<0.05). The pulse pressure variability was the highest at T 0 (18.76%±3.58%), followed by T 1 (14.81%±3.32%), T 2 (12.44%±2.94%), T 3 (10.39%±2.96%) and T 4 (9.18%±1.92%, P<0.05). The blood brain natriuretic peptide was higher at T 1 (846.67±362.95 pg/ml) than that at T 0 (42.60±18.06 pg/ml), T 2 (730.95±351.09 pg/ml), T 3 (510.98±290.39 pg/ml) and T 4 (364.41±243.56 pg/ml, P<0.05). There was no significant difference in left ventricular ejection fraction, cardiac circulation efficiency and heart index between the two groups (P>0.05). The right ventricular two-chambers view fraction area change of the transannular patch group was significantly lower than that of the non-transannular patch group at each time point (P<0.05). The blood brain natriuretic peptide and pulse pressure variability of the transannular patch group were significantly higher than those of the non-transannular patch group (P<0.05). Left ventricular ejection fraction was positively correlated with cardiac index (r=0.637, P=0.001) and cardiac circulation efficiency (r=0.462, P=0.001) while was significantly negatively correlated with blood brain natriuretic peptide (r=–0.419, P=0.001). Conclusion Both methods can accurately reflect the state of cardiac function. Mostcare monitor has a good consistency with echocardiography. Using transannular patch to recontribute right ventricular outflow tract in operation has more influence on right ventricular systolic function. The Mostcare monitor can guide the hemodynamic management after surgery in real time, continuously and accurately.
Objective To review the research progress of rapid surgery for hip fracture in elderly patients. Methods The published studies, expert consensus, and guidelines at home and abroad were systematically summarized from the aspects of the characteristics of aging population, the benefits of rapid surgery, the disadvantages of delayed surgery, and the recommendations of current guidelines, so as to further guide clinical practice. Results Hip fracture is a common fracture type in the elderly population. As elderly patients generally have poor physique and often have a variety of underlying diseases, such as hypostatic pneumonia, bedsore, lower limb vein thrombosis, and other complications in conservative treatment, its disability rate and mortality are high, so surgical treatment is the first choice. At present, most relevant studies and expert consensus and guidelines at home and abroad support rapid surgery, that is, preoperative examination should be started immediately after admission, and adverse factors such as taking anticoagulant drugs, serious cardiovascular diseases, and severe anemia should be clearly and actively corrected, and surgery should be completed within 48 hours after admission as far as possible. Rapid surgery can not only significantly reduce the mortality of patients, but also reduce the length of hospital stay and the incidence of perioperative cognitive impairment, which is conducive to the recovery of patients with pain during hospitalization and postoperative function, and improve the prognosis of patients. Conclusion In order to avoid many problems caused by delayed surgery, the elderly patients with hip fracture should be operated as soon as possible under the condition of actively correcting the adverse factors. Comprehensive evaluation and preparation, the development of an individualized surgical plan, and the formation of a multidisciplinary medical team can reduce surgical risks and improve effectiveness.
