ABSTRACT

Blast injury of the chest injury is the most common wound in modern war trauma and terrorist attacks, and is also the most fatal type of whole body explosion injury. Most patients with severe blast injury of the chest die in the early stage before hospitalization or during transportation, so first aid is critically important. At present, there exist widespread problems such as non-standard treatment and large difference in curative effect, while there lacks clinical treatment standards for blast injury of the chest. According to the principles of scientificity, practicality and advancement, the Trauma Society of Chinese Medical Association has formulated the guidance of classification, pre-hospital first aid, in-hospital treatment and major injury management strategies for blast injury of the chest, aiming to provide reference for clinical diagnosis and treatment.

ABSTRACT

Objective:To compare the clinical efficacy of extracorporeal membrane oxygenation (ECMO) and ventilation therapy in the treatment of severe blast lung injury.Methods:A retrospective cohort study was conducted to analyze the clinical data of 37 patients with severe blast lung injury admitted to 909th Hospital of Joint Logistics Support Force (Affiliated Dongnan Hospital of Xianmen University Medical College) from January 2000 to December 2021, including 23 males and 14 females; aged 26-50 years [(36.3±11.1)years]. The chest abbreviated injury score (AIS) was 3-5 points. In all, 16 patients were treated with ECMO from January 2017 to December 2021 (ECMO group) and 21 with ventilator from January 2000 to December 2016 (ventilator group). Blood gas analysis indexes [arterial pH, partial pressure of carbon dioxide (PaCO 2), partial pressure of oxygen (PaO 2), blood lactate (Lac)] and hemodynamics indexes [central venous pressure (CVP), cardiac output index (CI), pulmonary arterial systolic pressure (PASP), pulmonary capillary wedge pressure (PAWP)] were compared in the two groups at 30 minutes before treatment and at 2, 4, 6 hours after treatment. The mechanical ventilation time, ICU length of stay, acute physiology and chronic health evaluation II (APACHE II) score and mortality were measured at 7 days after treatment. Results:All patients were followed up for 24-48 months [(33.6±8.2)months]. The blood gas analysis and hemodynamic indexes were significantly improved in the two groups at 2, 4, 6 hours after treatment when compared with those at 30 minutes before treatment (all P<0.05), and the improvements were still statistically significant in ECMO group at 4, 6 hours after treatment when compared with those at 2 hours after treatment (all P<0.05), while not in ventilator group (all P>0.05). There was no significant difference in blood gas analysis indexes or hemodynamic indexes between the two groups at 30 minutes before treatment (all P>0.05). After treatment for 2, 4, 6 hours, blood gas analysis indexes and hemodynamic indexes in ECMO group were statistically different from those in ventilator group (all P<0.05). After treatment for 7 days, the mechanical ventilation time, ICU length of stay, APACHE II score and mortality were (3.2±1.2)days, (5.4±1.3)days, (14.1±3.3)points and 12.5% (2/16) in ECMO group, significantly different from (5.1±1.6)days, (7.6±1.6)days, (10.2±2.6)days and 28.6% (6/21) in ventilator group (all P<0.05). Conclusion:For severe blast lung injury, ECMO can attain rapid and continuous improvement of refractory hypoxemia and dyspnea, shorten the duration of mechanical ventilation and ICU length of stay and reduce the mortality rate when compared with ventilator therapy.

ABSTRACT

Objective:To compare the efficacy of standardized incision and conventional incision for reduction and internal fixation of multiple rib fracture.Methods:A retrospective cohort study was conducted to analyze the clinical data of 192 patients with multiple rib fracture treated in 909th Hospital of Joint Logistics Support Force (Affiliated Dongnan Hospital of Xianmen University Medical College) from January 2020 to January 2022. There were 101 males and 91 females; aged 32-94 years [(51.5±16.6)years]. The patients underwent open reduction and internal fixation with nickel-titanium shape memory alloy embracer via standard incision such as anterior axillary longitudinal incision (standard incision group, n=96) or conventional incision such as posterolateral incision (conventional incision group, n=96). The incision length, operation time, intraoperative blood loss, number of fixed fractures, indwelling time of closed thoracic drainage tube, postoperative thoracic drainage volume, postoperative spontaneous ambulation time and length of hospital stay were compared in the two groups. The visual analogue scale (VAS) was used to evaluate pain at 1 month after operation. Postoperative complications were recorded. Results:All patients were followed up for 1-16 months [4.0(3.0, 10.5)months]. The operation time, intraoperative blood loss, indwelling time of closed thoracic drainage tube, postoperative thoracic drainage volume, postoperative spontaneous ambulation time, length of hospital stay and VAS at postoperative 1 month in standard incision group [(12.1±1.6)cm, (51.4±13.0)minutes, (191.5±16.8)ml, (2.8±0.6)days, (568.9±109.0)ml, (4.1±0.7)days, (11.4±1.7)days, (2.5±0.7)points] were better than those in conventional incision group [(13.7±1.9)cm, (62.0±8.8)minutes, (248.9±65.4)ml, (4.8±1.1)days, (655.9±121.9)ml, (5.2±0.9)days, (15.3± 1.7)days, (3.5±0.7)points] ( P<0.05 or 0.01). There was no statistical difference in the number of fixed fractures between standard incision group and conventional incision group (5.1±0.8 vs. 5.4±0.9) ( P>0.05). In standard incision group, there were 3 patients with poor wound healing, 5 with pulmonary infection, 3 with atelectasis and 3 with small pleural effusion. In conventional incision group, there were 11 patients with poor wound healing, 9 with pulmonary infection, 7 with atelectasis and 7 with small pleural effusion. The incidence of postoperative complications was 14.6% (14/96) in standard incision group and 35.4% (34/96) in conventional incision group ( P<0.01). Conclusion:For multiple rib fracture, standard incision is superior to conventional incision reduction in shortening the incision length, operation time, indwelling time of drainage tube, postoperative spontaneous ambulation time and length of hospital stay, reducing the intraoperative blood loss and postoperative thoracic drainage volume, alleviating the pain and reducing the postoperative complications.

ABSTRACT

Objective:To investigate the risk factors of severe chest trauma complicated by acute respiratory distress syndrome (ARDS).Methods:A case control study was conducted to analyze the clinical data of 120 patients with severe chest trauma admitted to 909th Hospital of Joint Logistics Support Force (Affiliated Dongnan Hospital of Xianmen University Medical College) from January 2018 to December 2020. There were 75 males and 45 females; aged 21-72 years [(42.2±4.8)years]. The causes of injury were traffic injury in 57 patients, crush injury in 21, fall injury in 21, smash injury in 11 and others in 10. There were 34 patients accompanied by fracture of the limb, spine and pelvis, 23 by abdominal organ injury and 8 by head trauma, with the exception of simple thoracic trauma in 55 patients. The patients were divided into ARDS group ( n=25) and non-ARDS group ( n=95) according to the condition of concurrent ARDS. The two groups were compared regarding the gender, age, causes of injury, respiratory rate, lung contusion, lung infection, flail chest, chest abbreviated injury scale (AIS), hemothorax, blood pressure, partial arterial oxygen pressure (PaO 2), initial central venous pressure (CVP) on admission, combined fracture of the limb, spine and pelvis, combined head injury and combined abdominal organ injury. The correlation between the above indexes and ARDS after severe chest trauma was analyzed by univariate analysis. Multivariate Logistic regression analysis was used to determine the independent risk factors for ARDS after severe chest trauma. Results:Univariate analysis showed a positive correlation of ARDS with age, respiratory rate, lung contusion, lung infection, flail chest, chest AIS, hemothorax, blood pressure, PaO 2, initial CVP on admission, combined fracture of the limb, spine and pelvis and combined abdominal organ injury ( P<0.05 or 0.01), but not with gender, causes of injury or combined head injury (all P>0.05). Multivariate Logistic regression analysis revealed that age ≥60 years ( OR=2.45, 95% CI 1.81-7.50, P<0.01), dyspnea (respiratory rate ≥28 times/minute or <10 times/minute) ( OR=9.55, 95% CI 2.26-9.38, P<0.01), lung contusion ( OR=6.78, 95% CI 1.84-6.96, P<0.01), lung infection ( OR=27.71, 95% CI 11.97-64.14, P<0.01), flail chest ( OR=8.97, 95% CI 2.29-14.97, P<0.01), chest AIS score ( OR=5.77, 95% CI 2.85-9.20, P<0.01), above medium amount of hemothorax ( OR=6.84, 95% CI 1.69-13.39, P<0.01), blood pressure <90 mmHg ( OR=7.93, 95% CI 1.64-11.84, P<0.01), PaO 2<60 mmHg ( OR=6.39, 95% CI 1.06-9.47, P<0.01) and absent initial CVP on admission ( OR=4.56, 95% CI 1.86-8.44, P<0.01) were significantly correlated with ARDS. Conclusion:Age ≥60 years, dyspnea (respiratory rate ≥28 times/minute or <10 times/minute), lung contusion, lung infection, flail chest, chest AIS, above medium l amount of hemothorax, blood pressure <90 mmHg, PaO 2<60 mmHg and absent initial CVP on admission are independent risk factors for ARDS in patients with severe chest trauma.

ABSTRACT

@#Objective To explore the clinical characteristics and rehabilitation training of abnormal lateral consonant, namely/l/, of pa-tients with functional articulation disorders (FAD). Methods 107 patients with FAD were observed of the clinical characteristics of/l/. 30 pa-tients with/l/articulation disorder accepted speech training. The correlation and simple linear regression analysis were carried out on/l/ar-ticulation disorders and age. Results The articulation disorder of/l/ mainly showed replacement for/n/,/y/,/r/,/d/ or omission. When/l/combined with vowels contained/i/and/ü/, the main error was omission. When/l/combined with vowels contained/a/,/o/,/e/or/u/, the er-rors trended to be replacement rather than omission. After speech training, the patients made less mistakes about/l/(P<0.001). The frequen-cy of/l/articulation disorders was negatively correlated with age (r=-0.840). The result of simple linear regression analysis showed that the determination coefficient was 0.422. Conclusion The/l/articulation disorder mainly shows replacement or omission, varied with the vow-els. The targeted rehabilitation training may be helpful. Age plays an important role in the outcome of/l/articulation disorder.

ABSTRACT

Objective To discuss the clinical characteristics of Hashimoto's thyroiditis accompanying with thyroid cancer. Methods Clinical data of 98 cases Hashimoto's thyroiditis accompanying with thyroid cancer were retrospectively reviewed. Results 2 cases underwent lateral thyroid lobectomy and isthmus resection. 58 cases underwent bilateral thyroid lobectomy. 35 cases underwent central lymph node dissection, with 15 cases of lymph node positive. 3 cases underwent modified radical dissection of cervical lymph nodes and all of them were proved to be lymph node positive. Metastasis rate is 25.0% and 52. 2% respectively for tumors whose diameter was less than 1 cm and greater than 1 cm. The difference has no statistic significance. Conclusions Hashimoto's thyroiditis usually accompany with thyroid papillary carcinoma and cervical lymph node metastasis can occur even if it's microcarcinoma. Lymph node metastasis rate increases with increasement of the tumor's diameter. Total thyroidectomy should be performed for Hashimoto's thyroiditis concomitant with thyroid cancer. And if necessary,lymph node dissection should be extended to the central region and lateral neck area.
