RESUMO
Objective:To investigate the types, incidences, and clinical characteristics of shock in polytrauma patients at different stages after polytrauma.Methods:A retrospective study was conducted on polytrauma patients admitted to multiple trauma centers from June 2020 to December 2021. The inclusion criteria were patients >18 years old and treated due to polytrauma. Exclusion criteria included an admission time of more than 48 h after trauma, a history of malignancy, or metabolic, consumptive, and immunological diseases. The early stage was defined as the period of ≤48 h after polytrauma, and the middle stage was defined as the period between 48 h and 14 days. The patient’s medical history, clinical manifestations, laboratory tests, imaging examination, injury severity score (ISS), and Glasgow coma scale (GCS) were collected. The types, incidences, and clinical characteristics of shock in different stages after polytrauma were analyzed, according to the diagnostic criteria of each type of shock. The differences between the groups were compared by Student’s t test, χ2 test or Mann-Whitney U test. Results:The incidence of the early and middle stage shock after polytrauma were 73.1% and 36.4%, respectively, with statistically significant difference between stages ( P<0.01). There were significant differences in the incidence of hypovolemic shock (83.6% vs. 28.4%), distributed shock (13.7% vs. 80.9%) and cardiogenic shock (3.5% vs. 6.6%) between stages (all P<0.05). The incidence of obstructive shock (8.4% vs. 9.7%, P>0.05) was similar between stages. The incidence of undifferentiated shock was 1.6% and 1.2%, respectively. There were 9.5% patients with multifactorial shock in the early stage and 14.4% in the middle stage. Totally 7 combinations of multifactorial shock were found in different stages after polytrauma. In the early stage, the combination of HS and DS accounted the highest ratio (42.3%) and followed by HS and OS for 28.8%. In the middle stage, the combination of HS and DS was the most common (48.6%) and followed by DS and OS (24.3%). Conclusions:The incidence of shock in polytrauma patients is high. Different types of shock can occur simultaneously or sequentially. Therefore a comprehensive resuscitation strategy is significant to improve the success rate of treatment.
RESUMO
Objective To summarize and evaluate the clinical effect of extraco-rporeal membrane oxygenation(ECMO) support for critically ill patients after heart surgery,and to explore the factors that influenced the prognosis of ECMO.Methods The clinical data of 67 patients undergoing ECMO admitted to the Second Hospital of Jilin University from August 2013 to July 2017 were retrospectively analyzed.The patient's age ranged from 22 months to 78 years,including 3 infants aged 22,24,30 months and 64 adults ranged from 32 to 78 years,the mean age was(56.52 ± 10.99) years.Results The average ECMO support time was (235.79 ± 123.87) h,the mean mechanical ventilation time was (166.11 ± 148.31) h.49 patients weaned off successfully from ECMO,38 of them were discharged and 11 died within 28 days.18 patients gaved up treatment.42 patients suffered the complications.Conclusion VA-ECMO is a significant supportive method for preoperative intensive care in patients undergoing cardiovascular surgery.The keys to optimal results are grasping the indications of ECMO,earlier stopping mechanical ventilation,cluster curing(which involves reasonable anticoagulation,protection of organ function,prevention of hemorrhage,infection and limb distal ischemia).
RESUMO
BACKGROUND: Gastric bypass surgery and exenatide therapy represent two relatively new methods in treating morbid obesity and type 2 diabetes, although there are many differences between them. With the data supported from our hospital, we just want to investigate the differences between bypass surgery and exenatide injection and want to answer the question: Which one is the best? And Why? METHODS: Data from January 2009 to January 2010 were summarized for comparison at Shengjing hospital, including weight loss, plasma glucose and insulin changes, glycosylated hemoglobin, and the subjective scores of patients themselves. Plasma lipoprotein and serum ions were measured to evaluate the nutrition status. RESULTS: Patients in the GB group received more weight loss and better glucose control compared with the EX group. At 6 months, feeding insulin level in the GB group was 18.1 ± 3.2 mU/L, which was much lower than that in the EX group (64.5 ± 13.2 mU/L, P < 0.01). The Hb1AC level in the GR group was 6.08 ± 0.56 %, much lower than that in the EX group (7.19 ± 0.72 %, P < 0.01). We did not find any statistical differences in lipoprotein, plasma ions, and subjective scores between the GB and EX groups. CONCLUSIONS: Gastric bypass surgery is better in weight control and in the remission of insulin resistance compared with exenatide therapy. Both methods were safe and have no nutritional disorder in early stage, although the transferring in the GB group was higher than the EX group. The subjective scores from both groups declared that both methods could be accepted by patients.
