ObjectiveTo explore the corresponding intervention measures to reduce maternal mortality rate by analyzing the causes and problems of maternal deaths. MethodsA retrospective analysis was conducted to analyze all cases of maternal mortality from January 2005 to June 2013 in West China Second University Hospital. ResultsAmong the 14 cases of maternal deaths, the main diseases of the patients were pregnancy complicated with heart disease, hypertensive disorders, obstetric hemorrhage, amniotic fluid embolism and ectopic pregnancy. Four cases got prescriptive prenatal care during pregnancy, accounting for 28.6% (4/14), while 10 cases did not, accounting for 71.4% (10/14). Six patients died in prenatal period which accounted for 42.9% (6/14), while 8 died in postnatal period which accounted for 57.1% (6/14) and 5 died within 24 hours which accounted for 62.5% (5/8). Seven underwent cesarean section and 6 fetuses survived. Two went through trial of labor and no fetus survived. There was no ordered postmortem. ConclusionIntensifying education of prenatal care during pregnancy, improving quality of obstetrical service and diathesis of healthcare professionals, strengthening the supervision of high-risk pregnancy and timely choosing the time and manner of delivery are the main measures to decrease the maternal mortality.

Methods Four death cases after cardiac valve replacement between January 2008 and February 2010 were comprehensively analyzed from various aspects of surgery style, preoperational heart condition, peri-operational observations, results of forensic pathological tests, time of death, and causes of death. Results All cases were rheumatic heart disease and the preoperational heart function was poor. Of the four cases, three had mitral valve replacement (MVR), three had aortic valve replacement (AVR) and two had tricuspid valvuloplasty. Of the three MVR cases, cutting on the left atrium paralleling the interatrial groove was performed in one case, cutting through right atrium and interauricular septum was performed in one case, and cutting left atrium and right atrium through interauricular septum was performed in another case. For all the three AVR cases, cutting on the root of aorta with the shape of diagonal or ’S’ was carried out. One patient died during operation, one died thirty minutes after operation, one died two days after operation and one died eight days after operation. Among them, one died of myocarditis, one died of hemorrhage in the conducting system and two died of hemorrhagic shock. Besides, one patient had potential bacterial infection before surgery. Conclusion For patients who died after cardiac valve replacement, we should acquaintance ourselves with the preoperational heart condition, surgery style, surgical approach and the methods of stitch to make a comprehensive analysis with forensic pathology examination.
ObjectiveTo analyze the cause of death in low-risk cardiac surgery patients during postoperative period and discuss the prevention and treatment methods to increase the survival rate.MethodsWe retrospectively analyzed the clinical data of 132 patients dead after cardiac surgery from January 2014 to December 2018, among whom 35 patients had a EuroSCORE Ⅱ score <4% (low-risk cardiac surgery patients), including 20 males and 15 females aged 62.7±13.4 years. The cause of death in these low-risk patients was analyzed.ResultsThe main causes of death were cardiogenic and brain-derived causes (60.0%), and infections and ogran failure (45.7%). Pulmonary infection and low cardiac output after surgery were the main causes of death. Cerebral infarction, malignant arrhythmia and multiple organ failure were the common causes of death. There were 4 deaths (11.4%) caused by accidents, including gastrointestinal bleeding caused by esophageal ultrasound probe, cough and asphyxia caused by drinking water, postoperative paralytic ileus and multiple perioperative allergic reactions caused by allergic constitution.ConclusionPostoperative treatment and prevention for low-risk cardiac surgery patients should be focused on postoperative infection, and cardiac and brain function protection. Changes in various organ functions need to be closely monitored for preventing organ failure, accidents should be strictly controlled, and more details of intraoperative and postoperative treatment still need to be further improved.
Objective To explore the risk factors of premature infants death. Methods The medical records of hospitalized premature infants admitted to West China Second University Hospital of Sichuan University between January 2015 and December 2022 were collected. Premature infants were divided into the death group and the non-death group (control group) based on discharge diagnosis of death. Parturient and premature infants related information were collected, and the disease classification and diagnosis of premature infants were analyzed. Results A total of 13 739 premature infants were included, with 53 deaths and a mortality rate of 3.85‰ (53/13 739). The ages of death were 1-49 days, and the median age of death was (9.68±9.35) days. According to the matching method, 212 premature infants were ultimately included. Among them, there were 53 premature infants in the death group and 159 premature infants in the control group. Compared with the control group, premature infants in the death group had lower gestational age, birth weight, lower 1-minute Apgar scores, lower 5-minute Apgar scores and shorter hospital stay (P<0.05), and received more delivery interventions (P<0.05). There was no statistically significant difference in other indicators between the two groups of premature infants (P>0.05). A total of 212 parturient were included. Among them, there were 53 parturients in the death group and 159 parturients in the control group. The use rate of prenatal corticosteroids in the control group was higher than that in the death group (55.35% vs. 54.72%). There was no statistically significant difference in other related factors between the two groups of parturient (P>0.05). The results of logistic regression analysis showed that longer hospital stay [odds ratio (OR)=0.891, 95% confidence interval (CI) (0.842, 0.943), P<0.001], prenatal use of corticosteroids [OR=0.255, 95%CI (0.104, 0.628), P=0.003] reduced the risk of premature infant death. However, tracheal intubation [OR=10.738, 95%CI (2.893, 39.833), P<0.001] increased the risk of premature infant death. Conclusions Clinicians should pay attention to prenatal examination of newborns and pay attention to evaluation of newborn status. Obstetricians and neonatologists should make joint plans for women with high risk factors for preterm delivery. During the hospitalization, after the diagnosis is clear, standardized treatment should be carried out in strict accordance with the guidelines for systemic diseases and expert consensus.
