Application of point-of-care ultrasound in monitoring gastric residual volume in neurosurgical critical patients with enteral nutrition support / 中国中西医结合急救杂志

Objective To explore the feasibility and guiding value of point-of-care ultrasound (PoCUS) in evaluating gastric residual volume (GRV) in the course of implementing enteral nutrition (EN) in patients with neurological critical illness. Methods Ninety patients with critical neurological diseases necessary for EN were admitted to the Department of Intensive Care Unit (ICU) of Taizhou Hospital of Integrated Traditional Chinese and Western Medicine from March 1, 2017 to September 30, 2018 were selected, and they were randomly divided into a GRV extraction group (control group) and a PoCUS GRV group (study group), 45 patients in each group. Both groups were fed with Ruidai nutrient solution by nasogastric pump at a rate of 18 hours per day to persistently administer the target feeding volume for consecutive 7 days. The differences in tolerance of EN, the incidence of feeding interruption, the daily volume of EN fluid, the ratio of reaching total enteral nutrition (TEN) and the levels of serum albumin (Alb), prealbumin (PA) and prognosis were compared between the two groups. Results The incidences of reflux and wrong aspiration in the study group were significantly lower than those in the control group [8.9% (4/45) vs. 24.4% (11/45) and 4.4% (2/45) vs. 17.8% (8/45), both P < 0.05]. The EN liquid volume, ratio of reaching TEN, Alb and PA levels in the study group were significantly higher than those in the control group [EN liquid volume (mL/d): 944.6±277.1 vs. 783.7±230.5, the ratio of TEN: 86.7% (39/45) vs. 68.9% (31/45), Alb (g/L): 30.6±3.0 vs. 29.4±2.4, PA (g/L): 280.5±31.8 vs. 267.7±28.4, all P < 0.05]. The incidence of diarrhea [15.6% (7/45) vs. 13.3% (6/45)], the incidence of feeding interruption [8.9% (4/45) vs. 13.3% (6/45)], the length of stay in ICU (days: 10.4±6.2 vs. 8.3 ±5.4), the mortality [8.9% (4/45) vs. 13.3% (6/45)] had no significant differences between the two groups (all P > 0.05). Conclusion Evaluating GRV by PoCUS to adjust EN implementation plan can reduce the incidences of reflux and wrong aspiration and increase the EN intake.

Diagnostic value of abdominal ultrasound for neonatal necrotizing enterocolitis / 中国新生儿科杂志

Objective To study the diagnostic value of abdominal ultrasound for neonatal necrotizing enterocolitis (NEC). Method Neonates diagnosed with NEC admitted to Department of Shengjing Hospital from January 2016 to December 2018 were retrospectively analyzed. They were assigned into NEC stage Ⅱ group and NEC stage Ⅲ group based on the modified Bell-NEC grading criteria. Meanwhile, according to the timing of imaging examination, the patients were assigned into the group within 7 days after the onset of NEC and the group between 8 and 14 days. They were then grouped into conservative treatment group and surgery group. The difference between abdominal X-ray plain film and abdominal ultrasound in the performance of diagnosing NEC within groups were compared. Result A total of 60 patients with NEC were studied, including 38 with NEC stage Ⅱand 22 with NEC stage Ⅲ, among them 14 patients underwent surgery, others had conservative treatment. The average gestational age was (33.3±3.2) weeks and the average birth weight was (2047±831) g. The positive detection rate of pneumatosis intestinalis and hepatic portal venous gas by abdominal ultrasound vs. X-ray plain film in≤7 d group were 38.3％ (23/60) vs. 15.0％ (9/60) (P=0.004) and 15.0％(9/60) vs. 1.7％ (1/60) (P=0.008), respectively, indicating the positive detection rate of abdominal ultrasound was significantly higher than that of X-ray within 7 d after the onset of NEC. However, there was no significant difference in the detection rate between abdominal ultrasound and abdominal X-ray 8～14 d after the onset of NEC (P>0.05). The detection rate of intestinal wall thickening and peritoneal effusion by abdominal ultrasound together with the detection rate of intestinal dilatation and free gas in abdominal cavity by abdominal X-ray plain film in the conservative treatment group were significantly lower than those in the surgery group (P<0.05). Conclusion Abdominal ultrasound can help detecting the characteristic features of NEC (pneumatosis intestinalis and hepatic portal venous gas) in time, which has great value for early diagnosis and assessing severity.

Early diagnosis biomarkers of neonatal necrotizing enterocolitis / 中国小儿急救医学

Necrotizing enterocolitis(NEC) is a serious disease of digestive tract common in prema-ture infants,which is acute onset with high risk of death.Its early clinical symptoms are not typical,and it lacks sensitivity in radiological examination,so it is sometimes unreliable only based on the clinical manifes-tation and imaging results for early diagnosis.Recently,some biomarkers have certain changes in the early onset of NEC,such as intestinal fatty acid binding protein,intestinal trefoil factor,β-glucosidase,fecal calpro-tectin,which have certain significance to guide the clinical treatment and evaluate the severity of NEC.
