ABSTRACT
【Objective】 To explore the effect of lactate and alkali deficiency on the need for red blood cell transfusion in emergency of patients with traumatic hemorrhagic shock. 【Methods】 A total of 126 patients with traumatic hemorrhagic shock in our hospital from January 2019 to December 2021 were retrospectively analyzed, and the 99 cases with effective treatment were divided into two groups according to the outcome of blood transfusion within 24 hours after admission: non-transfusion group (n=36) and transfusion group (n=63). The changes of lactic acid (Lac), alkali deficiency (BE), hemoglobin (Hb), hematocrit (Hct) at admission, hemoglobin (Hb), hematocrit (Hct) 24 hours after admission and the length of stay in ICU were compared between the two groups. The binary logistic regression was used to analyze the risk factors of whether there was a need for blood transfusion at the time of emergency admission. The correlation between individual and combined indicators of each risk factor and the need for blood transfusion were analyzed by the receiver operating curve (ROC). 【Results】 The mean level of Lac (2.90±1.82) in the non-transfusion group at admission was lower than that in the transfusion group (5.80±2.83) (P0.05)The maximum AUG of Lac and BE(0.875, 0.766) in predicting the need for emergency red blood cell transfusion in patients with traumatic hemorrhagic shock was significantly better than that of Hb and Hct (0.692, 0.682); the optimal threshold for Lac was >3.6 mmol/L, while the optimal threshold for Hb is ≤106 g/L; the maximum AUG obtained by ROC curve analysis combined with Lac, BE, Hb and Hct was 0.910, which was higher than that of the sole virable. Comparative predictive value using the optimal thresholds of Lac and Hb as indications for transfusion showed that Lac had better predictive value than Hb. 【Conclusion】 Lac and be can be instructive for patients with traumatic hemorrhagic shock as to whether they need red blood cell transfusion in an emergency setting, and combination of Lac, BE, Hb and Hct may help to determine the transfusion needs of patients more timely and accurately and optimize the transfusion management of emergency patients.
ABSTRACT
Objective:To investigate the clinical efficacy and prognostic influencing factors of open abdomen technique for acute pancreatitis with abdominal compartment syndrome (ACS).Methods:The retrospective cohort study was conducted. The clinical data of 186 patients of acute pancreatitis with ACS who were admitted to 6 hospitals, including 65 cases in the 910th Hospital of Joint Logistics Support Force of Chinese People′s Liberation Army, 46 cases in the First Affiliated Hospital of Wenzhou Medical University, 33 cases in the Fujian Provincial Hospital, 31 cases in the Second Affiliated Hospital of Fujian Medical University, 7 cases in the People′s Hospital Affiliated to Quanzhou Medical College, 4 cases in the Shishi General Hospital, from January 2013 to December 2020 were collected. There were 142 males and 44 females, aged (43±8)years. Observation indica-tors: (1) patients conditions after being treatment with open abdomen technique; (2) analysis of clinical characteristics in patients with different treatment outcomes; (3) changing trend of the volume of urine output, levels of lactic acid, levels of enteral nutrient intake and the sequential organ failure score in patients with different treatment outcomes; (4) influencing factors for prognosis of patients. Measurement data with normal distribution were represented as Mean± SD, and compari-son between groups was analyzed using the t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was analyzed using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was analyzed using the chi-square test or the continuity correction chi-square test. Repeated measurement data were analyzed using the repeated ANOVA. Spearman correlation analysis was used for correlation analyses. The COX regression model was used for univariate analysis and COX regression model with forward regression was used for multivariate analysis. Results:(1) Patients conditions after being treatment with open abdomen technique. Intra-abdominal pressure, oxygena-tion index, levels of lactic acid and sequential organ failure score of the 186 patients were (23.3±1.9)mmHg (1 mmHg=0.133 kPa), (121±24)mmHg, (5.0±3.4)mmol/L and 10.4±3.6 before the treatment with open abdomen technique and (11.2±2.9)mmHg, (222±38)mmHg, (3.2±2.1)mmol/L and 4.4±2.3 at postoperative 168 hours, showing significant differences in time effects before and after the treatment ( Ftime=855.26,208.50, 174.91,208.47, P<0.05). (2) Analysis of clinical characteristics in patients with different treatment outcomes. Of the 186 patients, 166 cases survived and were discharged, and 20 cases died during hospitalization. Age, sequential organ failure score, duration of ACS and levels of lactic acid during hospitalization before the treatment with open abdomen technique were (41±7)years, 9.4±3.4, 13(10,21)hours and (4.2±0.6)mmol/L in surviving patients, versus (45±6)years, 11.5±2.4, 65(39,84)hours and (5.2±0.5)mmol/L in dead patients, respectively, showing significant differences between them ( t=-2.10, -2.71, Z=-5.36, t=-7.16, P<0.05). Duration of postoperative acute gastro-intestinal injury, duration of continuous renal replacement therapy, time to liberation from mech-anical ventilation, duration of vasoactive drugs therapy, cases undergoing early abdominal closure, cases without intestinal fistula or with postoperative high-order intestinal fistula and low-order intestinal fistula during hospitalization after the treatment with open abdomen technique were 4(2,6)days, 4(3,7)days, 34(21,41)days, 3(2,6)days, 126, 131, 23, 12 in surviving patients, versus 13(10,17)days, 10(8,18)days, 0(0,3)days, 8(6,12)days, 1, 2, 15, 3 in dead patients, respectively, showing significant differences between them ( Z=-5.60, -3.75, -3.64, -3.06, χ2=41.43, 45.86, P<0.05). (3) Changing trend of the volume of urine output, levels of lactic acid, levels of enteral nutrient intake and the sequential organ failure score in patients with different treatment outcomes. The volume of urine output, levels of lactic acid, levels of enteral nutrient intake and the sequential organ failure score in surviving patients during hospitalization were (0.29±0.10)mL/(kg·h), (4.2±0.6)mmol/L, 0.0 kcal/(kg·d) and 9.4±3.4 before the treatment with open abdomen technique and (2.22±0.15)mL/(kg·h), (1.9±0.7)mmol/L, (20.7±2.9)kcal/(kg·d) and 3.7±2.2 at postoperative 168 hours. The above indicators in dead patients during hospitalization were (0.28±0.08)mL/(kg·h), (5.2±0.5)mmol/L, 0.0kcal/(kg·d) and 11.5±2.4 before the treatment with open abdomen technique and (0.28±0.09)mL/(kg·h), (7.7±0.8)mmol/L, (4.6±1.8)kcal/(kg·d) and 12.4±2.1 at postoperative 168 hours. There were significant differences in time effects in the above indicators in surviving patients and dead patients before and after the treatment with open abdomen technique ( Ftime=425.57, 188.59, 394.84, 37.52, P<0.05). There were interactive effects between the above indicators and the treatment outcome at different time points ( Finteraction=383.14, 233.04, 169.83, 36.61, P<0.05). There were signifi-cant differences in the change trends of the above indicators between the surviving patients and the dead patients during hospitalization ( Fgouprs=2 739.56, 877.98, 542.05, 240.85, P<0.05). (4) Influen-cing factors for prognosis of patients. Results of univariate analysis showed that age, sequential organ failure score, duration of ACS before surgery, procalcitonin, lactic acid, postoperative high-order intestinal fistula, abdominal hemorrhage, duration of postoperative acute gastrointestinal injury, duration of continuous renal replacement therapy, duration of vasoactive drugs therapy, early abdominal closure were related factors influencing prognosis of patients under-going treatment with open abdomen technique ( hazard ratio=1.07, 1.18, 1.39, 1.16, 8.25, 12.26, 2.83, 1.29, 1.56, 1.41, 0.02, 95% confidence interval as 1.00-1.15, 1.45-2.27, 1.22-1.57, 1.02-1.32, 1.75-38.90, 7.37-41.23, 1.16-6.93, 1.22-1.37, 1.23-1.99, 1.08-1.84, 0.00-0.16, P<0.05). Results of multivariate analysis showed that extended duration of ACS before surgery, postoperative high-order intestinal fistula and extended duration of postoperative acute gastrointestinal injury were independent risk factors influencing prognosis of patients undergoing treatment with open abdomen technique ( hazard ratio=1.05, 7.95, 1.17, 95% confidence interval as 1.01-1.32, 2.05-30.87, 1.13-1.95, P<0.05) and early abdominal closure was an independent protective factor ( hazard ratio=0.10, 95% confidence interval as 0.01-0.89, P<0.05). Results of Spearman correlation analysis showed that duration of ACS was positively correlated with sequential organ failure score before surgery ( r=0.71, P<0.05). Conclusions:Open abdomen technique is effective for acute pancreatitis with ACS. Extended duration of ACS before surgery, postoperative high-order intestinal fistula and extended duration of postoperative acute gastrointestinal injury are independent risk factors for prognosis of patients during hospitalization and early abdominal closure is an independent protective factor.
ABSTRACT
Background:In the clinical setting, the effect of intra-abdominal hypertension on the human body is dependent on time, but its role is not yet clear.Objective:To investigate the effect of the duration of intra-abdominal hypertension (IAH) on the prognosis of critically ill patients.Methods:This prospective cohort study enrolled 256 IAH patients who were admitted to the Surgical ICU of 10 Grade A hospitals in Fujian Province from January 2018 to December 2020. The duration of IAH (DIAH) was obtained after monitoring IAP, and ICU length of stay, duration of mechanical ventilation, duration of continuous renal replacement therapy (CRRT) and average daily energy intake from enteral nutrition during ICU stay were observed and recorded. The correlation was analyzed by Spearman rank correlation. The patients were divided into the survival group and the death group according to their survival state at 60 days after enrollment. Thereafter, clinical characteristics between the two groups were compared. Multivariable logistic regression was used to study and validate the relationship between DIAH and 60-day mortality. The receiver operating characteristics (ROC) curve was established to evaluate the predictive abilities of DIAH on the mortality risk.Results:In critically ill patients, DIAH was positively correlated with duration of mechanical ventilation ( r=0.679, P<0.001), duration of CRRT ( r=0.541, P<0.001) and ICU length of stay ( r=0.794, P<0.001), respectively. In addition, there was a negative correlation between DIAH and average daily energy intake from enteral nutrition ( r=-0.669, P<0.001). After multivariable adjustment, DIAH was an independent risk factor for 60-day mortality in critically patients with IAH ( OR=1.05, 95% CI: 1.01-1.12; P = 0.012), and exhibited a linearity change trend relationship with mortality risk. The ROC curve analysis of DIAH showed that the area under ROC curve (AUC) was 0.825 (95% CI: 0.763~0.886, P<0.01). When the cut-off value was 16.5 days, the sensitivity was 78.4% and the specificity was 75.4%. Conclusions:DIAH is an important risk factor for prognosis in critically ill patients. Early identification and rapid intervention for the etiology of IAH should be performed to shorten DIAH.
