ABSTRACT
Feeding intolerance is a common cause of enteral nutrition interruption, which has a high incidence in the pediatric intensive care unit.It seriously affects the nutritional management of critically ill children, affects the treatment effect of critically ill children, and can lead to serious complications and even death.There is a lack of standardized and unified standards for the assessment of feeding intolerance in clinical practice, and there is an urgent need for objective and standard assessment tools.Ultrasound is a non-invasive, simple and non-radiation clinical technique, which can be used to measure gastric residual volume at the bedside in critically ill children, and evaluate feeding intolerance.
ABSTRACT
ABSTRACT Introduction: By July 2023, Brazil had administered approximately 540 million COVID-19 vaccine doses. This study aimed to quantify wasted doses resulting from dead space in vaccine supplies. Methods: The vaccine supply was initially weighed, filled with distilled water, and expelled to simulate administration. Weighing it again after the application determined the dead space volume. Descriptive analyses calculated the waste rate/wasted dose count. Results: The estimated total number of wasted vaccine doses using supplies with the lowest dead space was 62,097,338. Conclusions: Syringe dead space is a crucial factor in dose wastage, directly influencing the number of wasted doses.
ABSTRACT
Gastric residual volume (GRV) has been widely used in clinical practice for a long time as an essential indicator of gastrointestinal motility and enteral nutrition tolerance. Recent studies have questioned the rationality of monitoring GRV routinely in critically ill patients. A "one size fits all" principle is not an optimal solution in the clinical practice of enteral nutrition in critically ill patients because of the huge heterogeneity of the intensive care unit (ICU) population. Each method of monitoring GRV has advantages and disadvantages. With the widespread clinical application of harmless monitoring technologies such as ultrasound, the gastric suctioning method maybe used less and less. The management of enteral nutrition focuses on identifying the factors and triggers of gastric retention, attempting to solve them from the perspective of prevention and elimination of high-risk factors for aspiration and analysis of pathophysiological mechanisms, eliminating all negative hindering factors, and actively promoting the concept of "creating conditions for enteral nutrition". As a critical nutrition management team, it is necessary to pay attention to the continuous improvement of enteral nutrition management culture and rationally use diversified management strategies, which may be more important than monitoring GRV.
ABSTRACT
Objectives: To evaluate breast cancer (BC) patients treated with neoadjuvant chemotherapy (NACT) and to analyze clinicopathological features correlating with pathological complete response (PCR) and survival outcomes. Methods: Observational, descriptive, and retrospective study. The medical records of BC patients who underwent NACT were reviewed and analyzed using the Statistical Package for the Social Sciences (SPSS), version 20.0. Results: Of the 176 BC patints who underwent NACT, 62 patients (35.2%) achieved PCR. The PCR rate was 22% (n = 2) for luminal A, 15% (n = 9) for luminal B/HER2-negative, 45.5% (n = 15) for luminal B/ HER2-positive, 50% (n = 14) for non-luminal/HER2-positive, and 47.8% (n = 22) for triple-negative (p = 0.01). Histological grade, estrogen receptor (ER) expression, progesterone receptor (PR) expression, and HER2 status were significantly associated with PCR (p = 0.022, p = 0.01, p = 0.01, and p = 0.02, respectively). The median follow-up was 35.9 months, the estimated 5-year disease-free survival (DFS) was 96.7% in the PCR group and 83.2% in the non-PCR group (p = 0.05). The estimated 5-year overall survival (OS) was 95.5% in the PCR group and 69.1% in the non-PCR group (p = 0.017). Overall, 11 patients (6.25%) presented with locoregional recurrence (LRR), one (1.6%) in the PCR group and 10 (8.8%) in the non-PCR group (p = 0.10). Conclusion: We observed higher PCR rates in triple-negative and HER2-positive molecular subtypes. DFS and OS were significantly better in patients who achieved PCR, regardless of clinicopathological features. We also observed lower rates of LRR in the population that reached PCR.
ABSTRACT
Abstract Objective: To verify the concurrent validity between the inspiratory muscle strength (IMS) values obtained in static (maximal inspiratory pressure [MIP]) and dynamic (S-Index) assessments. Methods: Healthy individuals were submitted to two periods of evaluation: i) MIP, static maneuver to obtain IMS, determined by the Mueller's maneuver from residual volume (RV) until total lung capacity (TLC); ii) and S-Index, inspiration against open airway starting from RV until TLC. Both measures were performed by the same evaluator and the subjects received the same instructions. Isolated maneuvers with differences < 10% were considered as reproducible measures. Results: Data from 45 subjects (21 males) were analyzed and that showed statistical difference between MIP and S-Index values (133.5 ± 33.3 and 125.6 ± 32.2 in cmH2O, respectively), with P=0.014. Linear regression showed r2=0.54 and S-Index prediction formula = 39.8+(0.75×MIP). Pearson's correlation demonstrated a strong and significant association between the measures with r=0.74. The measurements showed good concordance evidenced by the Bland-Altman test. Conclusion: S-Index and MIP do not present similar values since they are evaluations of different events of the muscular contraction. However, they have a strong correlation and good agreement, which indicate that both are able to evaluate the IMS of healthy individuals.

Abstract Introduction: Breast cancer (BC) is the most frequent and lethal chronic non-communicable disease in women, and available information on the impact that the different treatments for BC have on the respiratory system is controversial. Objective: To determine the effect of concurrent chemotherapy and radiotherapy on lung volumes in a group of women with BC living in Talca, Chile. Material and methods: Case-control study. The sample (n=22) was divided into two groups: control (n=11) and BC (n=11). A whole body plethysmography test was used to measure participants' forced vital capacity, lung volumes, and airway resistance. The Shapiro-Wilks test was used to determine the normality of data, and, according to the result of this test, the Student's t test or the Mann-Whitney U test were used. A significance level of p<0.05 was considered. Results: Ventilatory flows showed no significant differences between both groups, while lung volumes in the BC group experienced a significant decrease in the inspiratory capacity (IC) and residual volume (RV) variables (p<0.05). Conclusion: Compared to the CG, the women with BC who received concurrent chemotherapy and radiotherapy experienced a reduction of their IC and RV, which could affect their quality of life.
ABSTRACT
OBJECTIVE: To observe the clinical therapeutic effect of acupuncture of Huatuo Jiaji (EX-B2) in the treatment of gastrointestinal dysfunction in sepsis patients, aiming at providing new clinical approach and evidence for improving septic gastrointestinal activity. METHODS: A total of 40 patients with septic gastrointestinal dysfunction who met our inclusive criteria were randomly divided into control group and treatment group (n＝20 cases in each). Patients in the control group received routine treatment of nasogastric mosapride citrate (5 mg/time, three times a day) and tifidobacterium triple viable capsules (420 mg, twice a day), intravenous infusion of omeprazole (40 mg, twice a day), rational dose of antibiotics, maintenance treatment of functions of the heart, lung, brain, kidney and other important organs and water electrolyte balance, as well as symptomatic treatment. Patients of the treatment group were treated by acupuncture of EX-B2 on the basis of routine treatment mentioned above in the control group. The acupuncture needle was inserted into EX-B2, twirled for a while and retained for 30 min, once a day for 10 successive days. The acute physiology and chronic health evaluation (APACHE II) score was given according to Knaus and colleagues' method, the intra-abdominal pressure was detected by using a manometer which was connected to an inserted canal in the urinary bladder, and the intragatric residul volume detected by using an injection syriange pumping via a nasal feeding tube. RESULTS: After the treatment, the APACHE II score, intra-abdominal pressure and intragastric residual volume on day 10 were significantly decreased in both groups in comparison with their own pre-treatment (P<0.05), while the borborygmus levels on day 10 were considerably increased in both groups relevant to their own pre-treatment (P<0.05). The APACHE II scores, intra-abdominal pressure and intragastric residual volume on day 3, 6 and 10 were significantly lower in the treatment group than those in the control group (P<0.05), whereas the borborygmus levels at the 3rd , 6th and 10th day in the treatment group were apparently higher than those of the control group (P<0.05)．. CONCLUSION: Acupuncture stimulation of EX-B2 has a good curative effect in improving gastrointestinal dysfunction in sepsis patients.

ABSTRACT
Objective To evaluate the relationship between postoperative residual pancreatic volume and change of blood glucose levels. Method Eighty?five cases of pancreatic benign and malignant tumor patients with preoperative and postoperative pancreatic CT images and clinical data were included retrospectively. Preoperative and postoperative pancreatic volume in benign patients and malignant patients were measured. Eight five patients were divided into 5 groups according to the resection volume ratio. Blood glucose levels were compared at different resection volume ratios. Correlation analysis of pancreatic resection volume ratio and blood glucose level were conducted in 39 benign patients and 46 malignant patients.ANOVA test, t test and Peason correlation coefficient were used. Result Postoperative benign and malignant group glucose level difference had statistical significance (P<0.05). Preoperative and postoperative malignant group of glucose level difference had statistical significance (P<0.05). Benign postoperative blood glucose between each groups was statistically significant (P<0.05); Malignant postoperative blood glucose between each groups was statistically significant (P<0.05); The volume ratio of benign and malignant tumor resection was positively correlated with postoperative blood glucose level (r values were 0.85 and 0.77, P<0.01). Conclusions There were statistically significant differences in blood glucose levels between pre?operation and post?operation of benign and malignant tumors. Postoperative blood glucose level was correlated with pancreatic resection volume, and postoperative blood glucose level was positively correlated with resection volume ratio.
ABSTRACT
Objective To evaluate the clinical implementation value of bedside ultrasound monitoring of gastric residual volume in the guidance of enteral nutrition (EN) in severe patients with mechanical ventilation. Methods One hundred and forty-three patients undergoing nasal feeding EN and mechanical ventilation ≥ 72 hours in the Department of Intensive Care Unit (ICU) of Jinhua People's Hospital from May 2017 to August 2018 were enrolled, and they were randomly divided into two groups: a traditional control group (71 cases) and an ultrasound monitoring group (72 cases). The traditional control group applied 50 mL syringe to withdraw gastric juice from gastric tube, once every 4 hours, and then the EN protocol based on the gastric residual volume was adjusted; the ultrasound monitoring group used bedside ultrasound to monitor the gastric residual volume once every 4 hours, and then the EN protocol was adjusted accordingly. The changes of EN tolerance indexes e.g. abdominal distension, reflux vomiting, diarrhea, bowel sound hyperactivity or disappearance, intra-abdominal pressure, etc, the changes of incidence of ventilator-associated pneumonia (VAP), mechanical ventilation time and ICU hospitalization time in these two groups were observed. Results The incidences of abdominal distension, reflux vomiting, diarrhea, intestinal hyperactivity or disappearance of bowel sounds were significantly lower in the ultrasound monitoring group than those in the traditional control group [abdominal distension: 23.6% (17/72) vs. 28.2% (20/71), reflux vomiting: 18.1% (13/72) vs. 22.5% (16/71), diarrhea: 13.9% (10/72) vs. 14.1% (10/71), bowel sounds hyperactivity or disappearance: 9.7% (7/72) vs. 11.3% (8/71), all P < 0.05], the intra-abdominal pressure was obviously lower in the ultrasound monitoring group than that in the traditional control group [mmHg (1 mmHg = 0.133 kPa): 8.9±5.6 vs. 9.6±6.1, P < 0.05], and the incidence of VAP was significantly lower in the ultrasound monitoring group than that in the traditional control group [19.7% (14/72) vs. 23.9% (17/71), P < 0.05], the mechanical ventilation time and ICU hospitalization time were also significantly shorter in the ultrasound monitoring group than those in the traditional control group [mechanical ventilation time (days): 10.1±3.1 vs. 12.2±3.4, ICU hospitalization time (days): 16.8±4.2 vs. 20.6±4.8, all P < 0.05]. Conclusion The bedside ultrasound monitoring gastric residual volume can improve EN tolerance, reduce VAP incidence, and shorten the mechanical ventilation time and ICU hospitalization time in patients with mechanical ventilation.
ABSTRACT
Objective:To investigate the effect of bedside ultrasound in measuring the gastric residual volume in postoperative patients with rheumatic heart disease complicated with cachexia with enteral nutrition support.Method:From June 2015 to May 2017,60 patients with rheumatic heart disease complicated with cachexia who admitted in ICU were randomly divided into two groups,group A (routine enteral nutrition plan plus ultrasound monitoring GRV)and group B (routine enteral nutrition plan plus withdraw every 4h to monitor the GRV),to guide the implementation of enteral nutrition.Results:There was significant difference in Hb,TP and ALB levels between the two groups (P ＜0.05).The nutritional status of group A was better than that of group B.The incidence of gastric retention and pulmonary infection in group A was significant lower than group B (P ＜0.05).The length of target feeding time and ICU stay had a statistically difference in group A and group B [(3.02 ± 0.78) d vs (4.89 ± 0.69) d,t=2.278,P=0.019] and [(10.41 ± 1.98) d vs (11.39 ± 1.75) d,t=2.384,P=0.015].Conclusion:The application of bedside ultrasound to monitor the gastric residual volume can be an accurate method to guide enteral nutrition in postoperative patients with rheumatic heart disease complicated with cachexia,which can improve the nutrition status,shorten the length of target feeding time and ICU stay and reduce enteral nutrition-related complications.
ABSTRACT
Objective To compare the effects of gastric residual volume (GRV) set at different thresholds on intensive care patients receiving enteral nutrition (EN),so as to inform clinical practice.Methods Controlled clinical trials involving different GRV thresholds in ICU patients undergoing EN were retrieved from multiple electronic databases (including Cochrane Library,PubMed,Ovid Medline,Web of Science,CBM,CNKI,Wanfang Data,and VIP).Quality of the retrieved studies was evaluated for data extraction,and meta-analysis was performed.Results Four randomized controlled trials and one clinically controlled trial were included in the study,with a total of 658 subjects.Results of the meta-analysis suggested no statistically significant difference between the group with GRV threshold≥250 ml and the one with GRV threshold＜250 ml in the rates of pneumonia (OR =1.19,95％ CI =0.77-1.82,P =0.43),aspiration.(OR =1.59,95％ CI =0.42-6.03,P=0.50),vomiting (OR=1.35,95％ CI=0.48-3.80,P=0.57),reflux (OR=1.29,95％ CI=0.58-2.88,P=0.53),and diarrhea (OR=1.36,95％ CI=0.87-2.13,P=0.17).Nutrient intake and several other outcome measures were unable to be included in the meta-analysis for either the scarcity of studies or inconsistency in the measures adopted,and descriptive analysis was therefore employed instead.Conclusion There was no significant difference between the two groups in terms of complications,but the group with GRV threshold≥250 ml had higher intake of EN.
ABSTRACT
Abstract OBJECTIVE Quantifying residual volume contained in vials of antibiotics used in pediatrics. METHOD This is an experiment involving samples from vials of antibiotics used in a pediatric hospital. Residual volume was identified by calculating the difference in weight measurement before and after the vials were washed. Evaluation of the residual volume difference in the vials was determined by the Wilcoxon non-parametric test for a sample and established at a significance level of 5%. RESULTS 105 samples of antibiotics were selected. The correct use of the antibiotics oxacillin (88.57%) and ceftriaxone (94.28%) predominated with low residual values. The same did not occur for procaine benzylpenicillin + potassium benzylpenicillin, since a greater residual volume was discarded in 74.28% of the vials. CONCLUSION We highlight the need for improvements in managing antibiotics in the institution under study, so that the excess volume of the antibiotics in the vials is used within the acceptable stable time. It is also necessary that the disposal of the residual volume be adequately disposed, since it presents a risk to public health and the environment.

Objective To explore the difference in gastric residual volume (GRV) between singledose and split-dose bowel preparation before colonoscopy under general anesthesia.Methods From October 8th to December 30th in 2016,the out-patients undergoing gastroscopy and colonoscopy with anesthesia services on the same day were selected and divided into the traditional single-dose bowel preparation group and split-dose bowel preparation group.The GRV and intestinal preparation quality were compared between the two groups.T test was used for statistical analysis and multiple linear regression analysis was performed for the influence factors of GRV analysis.Results A total of 121 patients were enrolled,60 patients in the spilt-dose bowel preparation group and 61 in the traditional single-dose bowel preparation group.The mean GRV of the split-dose bowel preparation group was (17.3 ± 12.2) mL,which was lower than that of the single-dose bowel preparation group ((23.7 ± 14.6) mL),and the difference was statistically significant (t =2.642,P=0.009).The score of intestinal preparation quality of the split-dose bowel preparation group was 8.05 ± 0.85,which was higher than that of the single-dose bowel preparation group (7.67±1.19),and the difference was statistically significant (t =-2.002,P=0.048).Fasting time was related with GRV (odd ratios (OR)=1.732,95％ contidence interval (CI) O.299 to 3.168,P=0.018).Conclusion The GRV of patients with split-dose bowel preparation before colonoscopy is lower than that of traditional single-dose bowel preparation,thus reducing the risk of aspiration during anesthesia.
ABSTRACT
To investigate the accuracy and feasibility of Brix value on monitoring gastric residual volume (GRV) in patients with enteral nutrition. Fifty patients with enteral nutrition via nasogastric tube were enrolled. The GRV was measured by both ultrasonography and Brix value. The results were compared according to the methods. The Pearson correlation coefficients showed that GRV measured by these two ways was positively correlated (r=0.986, P<0.05). Moreover paired sample t-test showed that the discrepancy was not statistically significant (P>0.05) between different measurements. The consistency was analyzed by Bland-Altman graph, showing that the two measurements were consistent. Brix value is recommended to measure GRV due to its convenience and easy operation.
ABSTRACT
Clinicians monitor the gastric residual volume(GRV) of critical ill patients to minimize or prevent side effect of EN.Nevertheless,recommendations about the threshold GRV in critically ill patients treated with EN are not uniform.Many recent clinical studies had demonstrated that increasing the limit of GRV was associated with the increase in the diet volume ratio of ICU patients receiving EN,and it was not associated with adverse effects in gastrointestinal complications.This review summarizes the influence factors of GRV monitoring to evaluate the feasibility and necessity of increasing the threshold of GRV.
ABSTRACT
Precise measurement of postvoid residual (PVR) urine volume is a key factor in assessing patients with voiding dysfunction, including those with lower urinary tract problems. The safe and noninvasive ultrasound bladder scan is the preferred mode to measure PVR volume. However, this procedure has a false-positive rate up to 9%, in the presence of ovarian cysts, renal cysts, ascites, or uterine myoma with cystic degeneration. Until now, cystic lesions are known to cause false positivity in ultrasound bladder scanner. However, we encountered falsely-elevated PVR in two cases of non-cystic uterine myomas. We present these cases with detailed radiologic images and volume measurement data.

PURPOSE: To evaluate the change of residual volume of eye drop after instillation in patients with 23-gauge microincision vitrectomy surgery (MIVS). METHODS: Patient who were treated 23-gauge MIVS from November 2014 to July 2015 were included. The residual volume was defined as the amount of remnant eye drop in patient's eyes after instillation, calculated as the difference between instillation volume and spilled volume of eye drop. Calculation of residual volume of eye drop was performed one day before surgery, and daily from postoperative day 1 to day 5. RESULTS: Forty consecutive patients were included. The residual volume of eye drop decreased from 30.3 ± 1.4 µL at baseline to 13.0 ± 1.5 µL at day 1, 18.3 ± 1.6 µL at day 2, 24.7 ± 1.5 µL at day 3, and 27.9 ± 1.4 µL in day 4, postoperatively (p < 0.001, respectively). The volume at postoperative day 5 was 29.4 ± 1.3 µL, but it was not different from the volume at baseline (p = 0.105). The change of residual volume was significantly correlated with postoperative chemosis (r = 0.672, p < 0.001) and effected by the number of quadrant with postoperative chemosis (p < 0.05). CONCLUSIONS: This study shows that postoperative residual volume of eye drop after instillation decreased until postoperative day 4, and postoperative chemosis affects the change of residual volume. Thus, checking proper use of eye drops and teaching about instillation technique by physician is necessary for patients with 23-gauge MIVS.
