Influence of posttraumatic blood pressure variability on post-traumatic stress disorder / 中华危重病急救医学

Objective:To investigate the relationship between blood pressure variability (BPV) and incidence of post-traumatic stress disorder (PTSD) in trauma patients.Methods:Patients admitted to the department of emergency medicine of the Affiliated Hospital of Xuzhou Medical University for acute trauma from January 2018 to December 2021 were enrolled. The clinical data and blood pressure at admission (T1), 10 minutes before anesthesia (T2), 60 minutes after surgery (T3), and 24 hours after surgery (T4) were collected. Coefficient of variation of blood pressure variation [CV-BP, including coefficient of variation of systolic blood pressure (CV-SBP), coefficient of variation of diastolic blood pressure (CV-DBP), coefficient of variation of mean arterial pressure (CV-MAP)] and its quartile were calculated. Patients were divided into Q1 group (CV-MAP ≤ 7.27), Q2 group (7.27 < CV-MAP ≤ 9.50), Q3 group (9.50 < CV-MAP ≤ 14.05) and Q4 group (CV-MAP > 14.05) according to CV-MAP quartile. The PTSD symptoms of the patients were evaluated using the PTSD scale (PCL-5) one month later, and the patients were divided into the PTSD group and the non-PTSD group according to whether PCL-5 score higher than 38. Then the differences of the above indicators were compared and analyzed. Spearman correlation analysis was used to analyze the relationship between each index and PCL-5 score; the risk factors of PTSD were analyzed by univariate binary Logistic regression. Variables with P < 0.05 were included in the multivariate binary Logistic regression model. The receiver operator characteristic curve (ROC curve) was drawn to analyze the predictive value of CV-MAP on the incidence of PTSD. Results:A total of 112 patients were enrolled, including 24 in PTSD group and 88 in non-PTSD group. Compared with non-PTSD group, the proportion of women, T1 shock index, proportion of intraoperative and postoperative blood transfusion in PTSD group was higher. Besides, PTSD group also had longer PT, more intraoperative and postoperative blood transfusion, and lower postoperative hemoglobin (Hb) level (all P < 0.05). The T1 SBP, DBP, MAP and T4 MAP of patients in PTSD group were significantly lower than those in non-PTSD group [T1 SBP (mmHg, 1 mmHg≈0.133 kPa): 105.0 (86.3, 121.3) vs. 122.0 (112.0, 132.8), T1 DBP (mmHg): 62.5 (50.0, 77.3) vs. 76.0 (68.5, 82.8), T1 MAP (mmHg): 77.8 (60.4, 91.3) vs. 93.3 (82.5, 99.0), T4 MAP (mmHg): 83.8±9.1 vs. 88.7±10.4, all P < 0.05], CV-SBP, CV-DBP and CV-MAP were higher than those in the non-PTSD group [CV-SBP: 12.80 (10.12, 19.16) vs. 9.30 (6.07, 12.95), CV-DBP: 16.62±6.47 vs. 12.40±5.61, CV-MAP: 14.10 (9.25, 18.85) vs. 8.90 (6.93, 13.29), all P < 0.05]. Spearman correlation analysis showed that there was a positive correlation between CV-MAP and PCL-5 scores in patients with acute trauma ( r = 0.429, P < 0.001); multivariate binary Logistic regression analysis showed that only CV-MAP [odds ratio ( OR) = 1.128, 95% confidence interval (95% CI) was 1.015-1.254, P = 0.025] and CV-DBP ( OR = 1.114, 95% confidence interval (95% CI) was 1.016-1.221, P = 0.022) was the risk factor for PTSD in acute trauma patients. Compared with Q1 group, Q4 group was significantly more likely to develop PTSD ( OR = 18.6, 95% CI was 1.9-179.1, P = 0.012). CV-SBP, CV-DBP and CV-MAP had certain predictive value on PTSD diagnosis in patients with acute trauma according to ROC curve analysis results [area under the ROC curve (AUC) was 0.713, 0.682 and 0.726, respectively], among which CV-MAP has the highest predictive value. When the cut-off value of CV-MAP was 12.158, the sensitivity was 75.0% and the specificity was 69.3%. Conclusion:Higher BPV after trauma is a risk factor for PTSD. Maintaining stable blood pressure in trauma patients is of great significance for prevention and treatment of PTSD.

Relationship between neutrophil to lymphocyte ratio and post-traumatic stress disorder in early stage after acute trauma / 中华急诊医学杂志

Objective:To investigate the relationship between the changes in inflammatory markers levels and the onset of post-traumatic stress disorder (PTSD) in the early stage of acute trauma..Methods:From January 2018 to June 2020, patients with acute trauma who were admitted to the Affiliated Hospital of Xuzhou Medical University were selected as subjects. Peripheral venous blood was collected on admission, on the 3rd and 7th day after trauma for routine blood test, C-reactive protein (CRP) and procalcitonin (PCT). The neutrophil to lymphocyte ratio (NLR) was calculated. The PCL-5 scale was used to evaluate PTSD symptoms one month later. The patients were divided into the PTSD group and non-PTSD group with the score of 38 as the boundary. The change rule of NLR in the PTSD group and the non-PTSD group were analyzed.Results:Ninety-one trauma patients were enrolled, including 23 patients in the PTSD group and 68 patients in the non-PTSD group. Compared with the healthy control group, the NLR of 91 trauma patients on admission, on the 3rd and 7th day were significantly higher (all P< 0.01). The NLR of the PTSD group was increased on the 7th day after trauma, which was significantly higher than that of the non-PTSD group ( P= 0.025). The non-PTSD group showed a decreasing trend, of which NLR on the 7th day was significantly lower than that on admission ( P= 0.001). In addition, high level of NLR on the 7th day after trauma (β= 0.206, P= 0.01) was a risk factor for PTSD onset. Conclusions:Dynamic monitoring of the changes in NLR after acute trauma would be of great clinical value to early warning of PTSD.

Effect of intensive analgesia on post-traumatic stress disorder in patients with acute trauma / 中华急诊医学杂志

Objective:To explore the influence of intensive analgesia on the incidence of post-traumatic stress disorder (PTSD) in acute trauma patients, and to develop new ideas for the prevention and treatment of PTSD.Methods:From January 2018 to November 2019, a prospective study was conducted on trauma patients who visited the Emergency Center of Affiliated Hospital of Xuzhou Medical University and met the enrollment criteria. The patients were divided into the intensive analgesia group (< 4) and non-intensive analgesia group (≥ 4) according to the mean pain score in 30 days. The epidemiological data, trauma-related parameters, analgesic schemes, VAS score, PCL-5 score, HADS score and incidence of PTSD of enrolled patients were collected. Appropriate statistical methods were used to analyze differences among the indicators between the two groups.Results:Eighty-four acute trauma cases were included in the study, 39 cases in the intensive analgesia group and 45 in the non-intensive analgesia group. There was no significant difference in baseline data between the two groups (all P>0.05). The incidence rate of PTSD and PCL-5 score of patients in the intensive analgesia group were all significantly lower than those in the non-intensive analgesia group in 1 month after the trauma (all P< 0.05). The HADS anxiety and depression scores of patients in the intensive analgesic group were significantly lower than those in the non-intensive analgesic group (all P< 0.05). All the analgesics were converted into the dosage of dezocine for comparison. The total dosage of analgesics (dezocine) used in patients of the intensive analgesia group was significantly higher than that in the non-intensive analgesia group within 30 days after injury ( P< 0.05). Conclusion:In the acute trauma patients, intensive analgesia after trauma can significantly reduce the incidence of PTSD as well as improve anxiety and depression symptoms.

The effect of traumatic pain on the incidence of early post-traumatic stress disorder / 中华急诊医学杂志

Objective:To investigate the effect of post-traumatic pain on post-traumatic stress disorder (PTSD).Methods:A prospective trial was conducted with the recruitment of patients referred to the Emergency Center of Affiliated Hospital of Xuzhou Medical University for acute trauma from January 2018 to June 2019, with the exclusion criteria: age < 18 years, severe eye injury, severe craniocerebral injury and other critical conditions. The clinical data and written informed consent were collected at admission, the post-traumatic pain was assessed by VAS scores and the trauma severity was assessed by ISS score. APACHEⅡ score were evaluated within 24 h after admission. One month after trauma, patients with history of mental illness, or history of major psychogenic trauma within one year or drug addiction were further excluded. Accordingly, 64 eligible patients were evaluated by VAS, and the PCL-5 scale was used to evaluated their PTSD symptoms. The patients were divided into the PTSD group and non-PTSD group according to PCL-5 score≥ 38, and the difference between the two groups in post-traumatic VAS scores was compared. Logistic regression analysis was used to analyze the risk factors of PTSD. Spearman correlation analysis was adopted to establish the correlation between VAS score at admission and PCL-5 score at one month after trauma. The receiver operator characteristic (ROC) curve was used to analyze the predictive value of traumatic pain intensity for PTSD onset.Results:Sixty-four patients were selected and defined as the PTSD group ( n=19) and non-PTSD group ( n=45). The VAS score at admission was significantly higher in the PTSD group than that in the non-PTSD group ( P=0.006). There was no significant difference in VAS scores and VAS variations at 1 month, and in ISS scores at admission and APACHEⅡ scores within 24 h after admission between the two groups. Traumatic pain was an independent risk factor for PTSD ( P=0.043). VAS score at admission was positively correlated with PCL-5 score at 1 month post-traumatically ( r=0.355, P=0.004). In addition, ROC curve analysis showed that VAS score > 8 at admission had predictive value for PTSD (sensitivity=100%, specificity=33%, P=0.000 2). Conclusions:Post-traumatic severe pain is an independent risk factor for PTSD, which requires prompt medical intervention.
