ABSTRACT
Objective To analyze the related factors and the independent risk factors of death in patients with multiple injuries. Methods Data of 651 patients with multiple injuries treated in our hospital from June 2012 to June 2015 were retrospectively analyzed. According to the outcomes, patients were divided into effective group (n=608) and death group (n=43). Data of gender, age, cause of injury, the primary diseases related with the trauma, ISS score, number of trauma, time from injury to the treatment and the body parts of injury were compared between two groups. Logistic regression analysis was used to analyze the risk factors of death in multiple trauma patients. Results The proportion of patients≥60 years old, ISS score≥16 points, the number of trauma≥4, a major brain injury and time of trauma to the treatment ≥3 h were higher in death group than those of effective group (P<0.05). The independent risk factors for emergency death in multiple injuries included patients≥60 years old, major brain injury, ISS score ≥16 points and time of trauma to the treatment ≥ 3 h. The cause of death in patients with craniocerebral trauma (cerebral laceration) accounted for up to 27.91%(n=12), intracranial hematoma accounted for 20.93% (n=9), and traumatic hemothorax accounted for 11.63% (n=5). Conclusion The related factors and independent risk factors should be paid attention to doctors in emergency department, and the emergency plan should be made to reduce the death rate of emergency patients with multiple injuries.
ABSTRACT
Objective To study the effect of laparoscopic neoplasty and changes of procalcitonin (PCT) and cell-mediated immunity in elderly patients with duodenal ulcer perforation. Methods Forty-four elderly patients with duodenal ulcer perforation were divided into laparoscopic neoplasty group (n=20) and open neoplasty group (n=24).The level of PCT was assayed by colloid immunization. Blood levels of CD3+, CD4+, CD8+and natural killer (NK) cells were detected by flow cytometry before operation and at 0.5 h, 24 h, 48 h and the 7th day after operation.Surgical complications and postoperative hospital stay were observed in two groups. Results There was no significant difference in the activity of PCT before operation between two groups. There were no significant differences in CD3+, CD4+, CD8+ and NK cells 0.5 h before operation between two groups. The level of PCT was significantly lower at 24 h and 48 h after operation in laparoscopic group than that in open operation group (P<0.05). There were significant differences in the serum levels of CD3+, CD4+, CD8+and NK cells with time changes in two groups (P<0.05). There were significant decreases in CD3+, CD4+and CD8+at 24 h after operation than those before operation in two groups, which were significantly lower in open operation group than those of laparoscopic group except for CD8+. The levels of CD3+, CD4+and CD8+recovered to the levels before operation at 48 h after operation in laparoscopic group. In open operation group CD3+did not return to the level before operation at 7 d after operation. The levels of NK cells were decreased at 24 h after operation in two groups, but there was no significant difference in the level of NK cells between two groups. The level of NK cells returned to preoperative levels at 48 h after operation in laparoscopic group, while there was no significant difference in the level of NK cells before and after operation in open neoplasty group. Compared with the open neoplasty group, there were fewer complications and shorter hospital stay in laparoscopic group. Conclusion The laparoscopic repair operation for gastric and duodenal ulcer perforation has a fewer effects on the stress response and immune function in elderly patients, and has the advantages in the protection of immune function.
