Clinical Effects of Intensive Insulin Therapy Treating Traumatic Shock Combined with Multiple Organ Dysfunction Syndrome

The therapeutic effects of intensive insulin therapy in treatment of traumatic shock combined with multiple organ dysfunction syndrome （MODS） were investigated. A total of 114 patients with traumatic shock combined with MODS were randomly divided into two groups： control group （n=56） treated with conventional therapy, and intensive insulin therapy group （n=58） treated with conventional therapy plus continuous insulin pumping to control the blood glucose level at range of 4.4-6.1 mmol/L. White blood cells （WBC） counts, prothrombin time （PT）, serum creatinine （SCr）, alanine aminotransferase （ALT）, serum albumin and PaO2 were measured before and at the day 1, 3, 5, 7 and 14 after treatment. The incidence of gastrointestinal dysfunction, the incidence of MODS, hospital stay and the mortality were also observed and compared. After intensive insulin therapy, the WBC counts, SCr, ALT and PT were significantly reduced （P0.05）, but the level of serum albumin was significantly increased （P0.05） at the day 3, 5, 7 and 14. In the meantime, the PaO2 was significantly elevated at the day 3, 5 and 7 （P0.01） after intensive insulin therapy. The incidence of gastrointestinal dysfunction, the incidence of MODS, the length of hospital stay and the mortality were markedly decreased （P0.01）. The results suggest early treatment with intensive insulin therapy is effective for traumatic shock combined with MODS and can decrease the length of hospital stay and the mortality.

Effect of preoperative limited fluid resuscitation to the patients with traumatic shock

Objective： To investigate the effect of preoperative limited fluid resuscitation on the patients with traumatic shock. Methods： Eighty-nine patients with multiple injuries complicating with shock were treated in Changhai Hospital Between January 2002 to October 2005 and were divided into 3 groups according to the preoperative levels of systolic blood pressure （SBP）. SBP of group A and group B were about 70 and 80 mmHg, respectively; and the SBP of group C was over 90 mmHg. Results, （1） There was no significant difference in age, gender, and injury severity score （ISS）, initiated resuscitation time and initiated operation time among the 3 groups. Preoperatively, there was significant difference in the amount of fluid resuscitation and infused erythrocyte suspension among group A, B and C （1687 ± 96 ml, 2096 ± 87 ml, 2976±93 ml, P〈0. 05; and 294±110 ml, 404±113 ml, 798±230 ml, P〈0. 05）. （2） The hemoglobin level in group C （94±45 g/L） was lower than that in group A （110±22 g/L） and group B （103±24 g/L） （P〈0.05）. However, there was no significant difference in the level of hemoglobin between group A and B. （3） There was no significant difference in the incidence of acute renal failure （ARF） among the 3 groups. The incidence of acute respiratory distress syndrome （ARDS） of group C （31.2%） was higher than that of group A （16.7%） and group B （18.2%） （P〈0.05）. The mortality of group C （34.4%） was higher than that of group A （12. 5% ） and group B （12. 1% ） （P〈0.05）. Conclusion： Preoperative limited resuscitation applied on patients with traumatic shock can reduce blood loss, incidence of ARDS and mortality.

Treatment Analysis of Limb Fractures Combined with Traumatic Shock

Objective:To evaluate the treatment regimen and efficacy for limb fractures combined with traumatic shock(TS).Methods:A total of 88 patients with limb fractures combined with TS,admitted between January 2021 and December 2023,were selected.Patients were divided randomly using a numerical grouping method.The observation group underwent restricted fluid resuscitation combined with comprehensive treatment,while the reference group received conventional fluid resuscitation combined with comprehensive treatment.Recovery time,fracture prognosis,complications,severity of the condition,and post-fracture joint function were compared between the two groups.Results:The observation group showed shorter symptom recovery times,a higher rate of anatomical fracture reduction,and a lower complication rate compared to the reference group(P<0.05).After one week of treatment,the severity score of the condition in the observation group was lower than that of the reference group,and all joint function scores were higher in the observation group(P<0.05).Conclusion:Restricted fluid resuscitation combined with comprehensive treatment for limb fractures with TS can alleviate symptoms,improve fracture prognosis,reduce related complications,decrease the severity of trauma,and enhance joint function.The therapeutic effect is excellent.

Albumin resuscitation protects against traumatic/hemorrhagic shock-induced lung apoptosis in rats

Objective: To determine the effects of albumin administration on lung injury and apoptosis in traumatic/hemorrhagic shock (T/HS) rats. Methods: Studies were performed on an in vivo model of spontaneously breathing rats with induced T/HS; the rats were subjected to femur fracture, ischemia for 30 min, and reperfusion for 20 min with Ringer's lactate solution (RS) or 5% (w/v) albumin (ALB), and the left lower lobes of the lungs were resected. Results: Albumin administered during reperfusion markedly attenuated injury of the lung and decreased the concentration of lactic acid and the number of in situ TdT-mediated dUTP nick-end labelling (TUNEL)-positive cells. Moreover, immunohistochemistry performed 24 h after reperfusion revealed increases in the level of nuclear factor κB (NF-κB), and phosphorylated p38 mitogen-activated protein kinase (MAPK) in the albumin-untreated group was down-regulated by albumin treatment when compared with the sham rats. Conclusion: Resuscitation with albumin attenuates tissue injury and inhibits T/HS-induced apoptosis in the lung via the p38 MAPK signal transduction pathway that functions to stimulate the activation of NF-κB.

Analysis of the Emergency Rescue Nursing Intervention Effect and Rescue Success Rate for Patients with Traumatic Hemorrhagic Shock

Objective:To analyze the value of emergency rescue nursing intervention in the care of patients with traumatic hemorrhagic shock and its impact on the success rate of rescue efforts.Methods:A total of 80 patients with traumatic hemorrhagic shock were selected as samples,with the timeframe from July 2022 to July 2023.The patients were randomly divided into two groups using a random number table method.Group A received emergency rescue nursing,while Group B received routine nursing care.The success rate of rescue,rescue indicators,complication rates,and family satisfaction with nursing care were compared between the two groups.Results:The rescue success rate in Group A was higher than in Group B(P<0.05);the total blood loss in Group A was less,and the rescue time,full transportation time,and hospitalization time were shorter than in Group B(P<0.05);the complication rate of patients with traumatic hemorrhagic shock in Group A was lower than in Group B(P<0.05);the family satisfaction with emergency nursing care in Group A was higher than in Group B(P<0.05).Conclusion:Emergency rescue interventions for patients with traumatic hemorrhagic shock can reduce blood loss,shorten rescue times,and improve the success rate of shock rescue,providing a safe and effective approach.

Protective effect of albumin on lung injury in traumatic/hemorrhagic shock in rats

Objective. To determine the effect of albumin administration on lung injury in traumatic/hemorrhagic shock （T/HS） rats. Methods： Forty-eight adult Sprague-Dawley rats were divided into three groups randomly （ n = 16 in each group） ： Group A, Group B, Group C. In Group A, rats underwent laparotomy without shock. In Group B, rats undergoing T/HS were resuscitated with their blood plus lactated Ringer＇s （twice the volume of shed blood ）. In Group C, rats undergoing T/HS were resuscitated with their shed blood plus additional 3 ml of 5% human albumin. The expression of polymorphonuclear neutrophils CD18/CD11b in jugular vein blood was evaluated. The main lung injury indexes （the activity of myeloperoxidase and lung injury score） were measured. Results： Significant differences of the expression of CD18/11b and the severity degree of lung injury were found between the three groups. （P〈0.05）. The expression of CD18/CD11b and the main lung injury indexes in Group B and Goup C incresed significantly compared with those in Group A （P 〈0.05）. At the same time, the expression of CD18/CD11b and the main lung injury indexes in Group C decreased dramatically, compared with those in Group B （ P 〈0.05 ）. Conclusions ： The infusion of albumin during resuscitation period can protect lungs from injury and decrease the expression of CD18/CD11b in T/HS rats.

Opioid receptors associated with cardiovascular depression following traumatic hemorrhagic shock in rats

Objective: To elucidate which one of μ, δ and κ opioid receptors is involved in the cardiovascular depression following traumatic hemorrhagic shock. Methods: With traumatic hemorrhagic shock rat models, the changes of myocardial and brain μ, δ and κ opioid receptors and cardiovascular functions and their relationship with hemodynamic parameters were observed. The effects of δ and κ opioid receptor antagonists on hemodynamic parameters of traumatic hemorrhagic shock rats were observed. Results: Following traumatic hemorrhagic shock, the number of myocardial and brain δ and κ opioid receptors significantly increased, their affinity did not alter, and the increased number of δ and κ opioid receptors was significantly associated with the decreased hemodynamic parameters. However, μ opioid receptor in heart and brain did not obviously change. δ opioid receptor antagonist ICI174,864 and κ opioid receptor antagonist Nor binaltorphimine (50 μg, Icv) could significantly reverse those decreased hemodynamic parameters. Conclusions: It suggests that opioid receptors, especially δ and κ opioid receptors are closely related to the pathogenesis of traumatic hemorrhagic shock, and they play important roles in the depression of cardiovascular function following traumatic hemorrhagic shock.
