ABSTRACT
Objective:To study the clinical effect of different application times of antibiotics in patients with hypertriglyceridemic severe acute pancreatitis(HTG-SAP).Methods:The clinical data of 92 patients with HTG-SAP who were treated at the Department of Critical Care Medicine of the Second Affiliated Hospital of Anhui Medical University from January 2016 to February 2022 were analyzed retrospectively. There were 65 males and 27 females, aged (40.82±10.55) years old. These patients were divided into three groups based on the time of prophylactic use of antibiotics: the early prevention group (used within 72 h after admission, n=39), the delayed prevention group (used after 72 h after admission, n=30) and the nonprevention group ( n=23). The clinical data such as the general data, length of stay and all cause mortality rate of the three groups of patients were analyzed. Results:Compared with patients in the nonprevention group, the incidence rate of pancreatic/peripancreatic infection [10.0%(3/30) vs. 39.1%(9/23)] and the incidence rate of bloodstream infection [6.7%(2/30) vs. 34.8%(8/23)] in the delayed prevention group were significantly decreased (pancreas/peripancreatic infection: χ 2=6.31, P=0.012; bloodstream infection: χ 2=6.72, P=0.010). The infection rate of multiple/pan resistant bacteria in the early prevention group [23.1%(9/39)] was significantly higher than the nonprevention group [4.3%(1/23)] (χ 2=4.49, P=0.034). There were no significant differences in the all cause mortality rate, length of stay, duration of intensive care, hospitalization cost, incidence of intestinal fistula and retroperitoneal hemorrhage, and the proportion of patients requiring surgery among the 3 groups (all P>0.05). Conclusions:Pophylactic use of antibiotics within 72 h of hospital admission significantly reduced the incidence of pancreatic/peripancreatic infection and bloodstream infection in patients with HTG-SAP. There were no significant differences in the final prognosis among these patients with HTG-SAP treated with antibiotics at different times.
ABSTRACT
Objective:To explore the value of ultrasonic measurement of optic nerve sheath diameter (ONSD) in predicting the risk of death in patients with severe brain injury.Methods:This was a prospective observational study based on 84 postoperative patients with severe brain injury from January 2020 to September 2020 in our department. The patients were divided into two groups: the survival group and the deceased group. The clinical features between the two groups were compared. Receiver operating characteristic (ROC) curves were used to evaluate the sensitivity and specificity of ONSD, neuron-specific enolase (NSE) and the combination of the two in predicting death in patients with severe brain injury. Binary logistic regression was used to analyze the independent risk factors for death. A prediction model for the risk of death was constructed.Results:There were 61 cases (72.6%) in the survival group and 23 cases (27.4%) in the deceased group. There were significant differences in age, Glasgow coma score (GCS), ONSD and NSE at 12 h after surgery between the two groups. According to the ROC curve, the optimal cutoff levels of ONSD and NSE for predicting death were 5.5 mm and 21.75 ng/mL, respectively. When the two indicators were combined, the area under the curve was 0.897 ( P<0.01). At this threshold, the sensitivity and specificity were 100% and 70.5%, respectively. ONSD ( OR=9.713; 95% CI: 1.192-79.147) and GCS scores ( OR=0.492; 95% CI: 0.318-0.763) at 12 h after surgery were independent risk factors for death in patients with severe brain injury (both P<0.05). Conclusions:Early postoperative ONSD is an independent risk factor for death in patients with severe brain injury. The combination of ONSD and NSE has the best predictive effect.
ABSTRACT
Objective:To study the efficacy and safety of early abdominal puncture drainage (APD) in severe acute pancreatitis (SAP).Methods:A retrospective study was conducted on 189 patients with SAP who were managed at the Department of Intensive Medicine of the Second Affiliated Hospital of Anhui Medical University from January 2013 to May 2020. According to whether ultrasound-guided APD was performed within one week after admission to ICU, these patients were divided into 2 groups: patients treated with APD (the APD group) and patients treated without APD (the non-APD group). Clinical data, including the acute physiological and chronic health status (APACHE) Ⅱ score, modified Marshall score, sequential organ failure evaluation (SOFA) score, and prognostic indicators including the retroperitoneal percutaneous drainage (PCD) rate and length of hospital stay, were compared between the two groups before and 1 week after surgery.Results:Of the 189 SAP patients in this study, there were 110 males and 79 females, aged (52.5±17.4) years old. On admission to ICU, the blood amylase, C-reactive protein, procalcalonin, interleukin-6, APACHE II score, modified Marshall score and SOFA score in the APD group were significantly higher than those in the non-APD group. After 1 week of treatment, most clinical indicators in the 2 groups were significantly improved, and there were no significant differences between these indicators (all P>0.05). There were no significant differences in the abdominal infection, retroperitoneal PCD and mortality rates between the APD group and the non-APD group ( P>0.05). The length of hospital stay [29 (18, 45) vs 21 (15, 32) d] and ICU stay [5 (3, 11) vs. 7 (5, 17) d] in the APD group were significantly higher than those in the non-APD group ( P<0.05). Conclusion:For patients with SAP with peritoneal effusion, early APD effectively improved the condition and prognosis without increasing the peritoneal infection and mortality rates.
