1.Association between echocardiography utilization and prognosis in patients with cardiac arrest
World Journal of Emergency Medicine 2025;16(1):63-66
Despite efforts to develop treatment technology for cardiac arrest (CA), CA incidence and mortality rates are still high.[1,2] A recent study of CA patients in emergency departments revealed that the incidence of CA is increasing annually, and the in-hospital survival rate of CA patients is only approximately 28.7%.[3] Echocardiography has been widely used as an important monitoring tool in critical care and helps to identify the cause of shock, monitor hemodynamics, and guide fluid therapy utilization.[4] One study reported that approximately one-third of patients underwent formal echocardiography during hospitalization in the intensive care unit (ICU).[5]

3.Perinatal outcomes of isolated single umbilical artery in full-term birth
Chinese Journal of Perinatal Medicine 2015;(4):275-278
Objective To investigate the perinatal outcomes of isolated single umbilical artery (ISUA) in full-term birth. Methods We performed a retrospective study of 82 252 pregnant women (aged<35 years;singleton; full-term live birth; no known chromosomal/structural anomalies) who delivered between January 1, 2011 and January 1, 2012 in 39 hospitals in 14 cities in China. There were 273 cases with ISUA as study group and 1 092 cases with a three-vessel cord selected in a 1∶4 ratio as control group. Perinatal outcomes including delivery modes (vaginal delivery or emergency cesarean section for fetal reasons), birth weight and height, placental weight, umbilical cord length, Apgar scores at 1 min, and rate of neonatal asphyxia were analyzed retrospectively. Data were analyzed using the Chi-square test, two independent samples t-test or rank sum test. Results The incidence of ISUA was 0.3%(273/82 252). There was no difference between the two groups with regard to maternal age, parity, gravidity, smoking status, gestational age at birth, or rate of complications during pregnancy (gestational diabetes mellitus or pregnancy-induced hypertension) (all P>0.05). The birth weight in ISUA group and control group was (3 259±463) and (3 344±411) g (t=3.689), birth hight was (48.6±2.7) and (49.7±1.9) cm (t=8.368), placental weight was (508±72) and (543±153) g (t=3.114), umbilical cord length was (52.6±8.1) and (53.7±7.5) cm (t=1.983), and Apgar scores at 1 min were 9.0 (8.0-10.0) and 10.0 (9.0-10.0) (Z=11.831), respectively; the values in the ISUA group were lower than those in control group (all P < 0.05). No significant differences were observed in the rate of vaginal delivery and emergeny cesarean section for fetal reasons between the ISUA group and control group [52.8%(144/273) and 49.9%(545/1 092),χ2=0.704;19.4%(25/273) and 15.7% (86/1 092), χ2=1.162; both P>0.05]. Conclusions ISUA does not increase emergency cesarean delivery rates for the fetal reasons, but the fetal growth and development may fall behind those with a three-vessel umbilical cord. Monitoring during pregnancy and delivery should be intensified for fetuses with ISUA.

OBJECTIVE:To compare mental state and drug safety of puerperant underwent propofol and etomidate painless abortion after regain of consciousness. METHODS:102 puerperant underwent painless abortion were selected and randomly divided into control group and trial groups with 51 cases in each group. The control group received Propofol injection 2 mg/kg intravenous-ly,and the trial group received Etomidate fat emulsion injection 0.2 mg/kg intravenously. The changes of patient’s mental state were evaluated with Positive and Negative Emotions Scale (PANAS) before anesthesia and after regain of consciousness. The changes of HR,BP,MAP and SpO2 were observed and compared between 2 groups before anesthesia and 1,2,3 and 5 min after anesthesia. The anesthetic effect and ADR were compared between 2 groups. RESULTS:Compared to before anesthesia,positive mood scores of the trial group were increased slightly after regain of consciousness,while that of the control group were increased significantly;there was statistical significance before anesthesia and after regain of consciousness (t=9.023,P<0.05);there was statistical significance between 2 groups(t=8.367,P<0.05). Negative mood scores of 2 groups were decreased significantly af-ter regain of consciousness;there was statistical significance before anesthesia and after regain of consciousness(t=8.672,9.895, P<0.05). HR,BP MAP and SpO2 of 2 groups had no statistical significance within 5 min after anesthesia(P>0.05). The total effective rate of anesthesia in control group was 80.4%,while that of trial group was 78.4%;there was no statistical signifi-cance between 2 groups (χ2=1.273,P>0.05). The incidence of nausea,vomiting,dizziness and other ADR were similar in 2 groups,but the incidence of fantasy(39.2%)in control group was significantly higher in trial group(11.8%);there was statistical significance between 2 groups(χ2=10.120,P<0.05). CONCLUSIONS:Propofol and etomidate have good stability on the respira-tory and circulatory system,anesthetic effects are correspond to the incidence of ADR. Etomidate has a better safety. But the psy-chological status of patients in the propofol group is preceding than etomidate group.
