An Alternative Approach to Treatment of Hypophosphatemia in Nonsurgical Critically Ill Patients in Countries With Limited Resources

Background: Hypophosphatemia can complicate and prolong the treatment of critically ill patients, and it is even thought to be related to mortality rate. Objectives: The aim of this study is to determine whether using extemporary prepared phosphate buffer in pharmacy would help correct serum phosphate in critically ill patients. Methods: A prospective study was conducted at the medical intensive care unit over a period of 1 year and included 50 patients who were diagnosed with hypophosphatemia. Phosphate buffer was prepared at the pharmacy, and the dose range was recommended by a clinical pharmacist. Results: Patients were administered phosphate buffer via the nasogastric tube, and the doses chosen by the physicians depended on serum phosphate level and the severity of the patients’ clinical status. Serum phosphate levels were successfully corrected in all treated patients. The most frequently used dose was 60 mmoL/d, and in most patients 1-day therapy was sufficient. No adverse effects were observed. Conclusion: The phosphate buffer is an adequate alternative for the treatment of hypophosphatemia of nonsurgically critically ill patients. One-day therapy with the 60 mmoL phosphate dose divided into 3 single doses resulted in normalization of serum phosphate values in most patients.

Abstract Background: Refeeding syndrome (RFS) is a group of metabolic disorders associated with refeeding after starvation. However, the diagnostic criteria of RFS are highly heterogeneous. This study aimed to identify the best diagnostic criteria of RFS in critically ill patients.Methods: A multicenter, parallel, prospective trial enrolled patients (≥18 years) with mechanical ventilation for more than 3 days. RFS, defined as new-onset hypophosphatemia (<0.87mmol/L) within 72h after feeding and a decreased concentration of serum phosphate of more than 30%, from four hospital ICU of Zhejiang provinces in China. The primary endpoint was the 28-day mortality. Results: Between May 1, 2019 and April 30, 2020, 312 patients were enrolled. Of these, 302 patients were included and completed the trial. Except for APACHE II, there were no significant differences in age, gender, admission type, diagnosis, furosemide application, and hormone application. In the RFS2 and RFS3 groups, the APACHE II score was significantly higher than the non-RFS group (p=0.009 and p=0.01, respectively). In the nutritional baseline data, there were no significant differences between the groups in the PNI index, time to start of nutrition treatment, percentage of start nutrition within 48 hours, parenteral nutrition, feeding intolerance, and caloric intake and protein intake within first week. The NRS2002 score in group 2 and 3 was higher than the non-RFS group (p<0.001 and p=0.001, respectively). Moreover, the BMI index in group 3 was lower than the non-RFS group(p=0.001). Furthermore, the 28-day mortality increased in group 2 compared with the non-RFS group. The length of hospital stay in group 3 was significantly longer than that in the non-RFS group (p=0.008). More importantly, according to the preliminary RFS2 screening criteria, patients were further divided into patients with modified RFS and modified non-RFS. The nosocomial infection rate and 28- or 90-day mortality in the modified RFS group were higher than those of the modified non-RFS group (p=0.006 and p=0.02, respectively).Conclusions: The optimal criterion of RFS was a decrease in serum phosphate level of 0.65mmol/L and below, and a reduction of greater than 0.16 mmol/L within 72 h after starting nutritional support.

Abstract Background The incidence of acute kidney injury(AKI) is high in critically ill patients with rhabdomyolysis. Limited evidence was proved of the association between serum phosphate levels at intensive care unit(ICU) admission and the subsequent risk of AKI. Our study aims to assess if serum phosphate level at admission was independently associated with AKI risk in these patients. Methods This study extracted and analyzed data from Medical Information Mart for Intensive Care-Ⅲ(MIMIC-Ⅲ,version1.4). Rhabdomyolysis was defined as a peak creatine kinase(CK) level higher than 1000 U/L. Serum phosphate was measured within the first day into the ICU and was categorized to 4 groups(<2.6, 2.6-3.4, 3.5-4.5, >4.5mg/dl). AKI was defined according to the Kidney Disease Improving Global Outcome (KDIGO) guidelines. Adjusted smoothing spline plots and multivariate logistic regressions were carried out to explode the association between serum phosphate and risk of AKI. Subgroup analyse was applied to verify the consistency of the association.Results Three hundred and twenty-one patients(67.8% male) diagnosed as rhabdomyolysis were eligible for this analysis. AKI occurred in 204(63.6%) patients of total. Incidence of AKI with admission serum phosphate groups<2.6, 2.6-3.4, 3.5-4.5 and>4.5mg/dl were 52.6%, 56.8%, 68.4% and 75.9%, respectively. Smoothing spline curve showed that there was a positive curve between the elevated phosphate values and increasing risk of AKI, and there was no threshold saturation effect. In multivariate logistic regression, OR was 1.3(95%CI 1.1-1.6, P=0.012, P trend=0.034) after adjusting confounders. Subgroup analyses proved the consistency of the relationship in these patients except in the strata of creatine kinase.Conclusion In rhabdomyolysis patients admitted to ICU, serum phosphate level at admission was independently associated with an increased risk of AKI. As phosphate levels rise, the risk of AKI increased.

Objective To compare the outcomes of patients with and without a mean serum potassium (K+) level within the recommended range (3.5–4.5 mEq/L). Methods This prospective cohort study involved patients admitted to the medical intensive care unit (ICU) of Siriraj Hospital from May 2012 to February 2013. The patients’ baseline characteristics, Acute Physiology and Chronic Health Evaluation II (APACHE II) score, serum K+ level, and hospital outcomes were recorded. Patients with a mean K+ level of 3.5 to 4.5 mEq/L and with all individual K+ values of 3.0 to 5.0 mEq/L were allocated to the normal K+ group. The remaining patients were allocated to the abnormal K+ group. Results In total, 160 patients were included. Their mean age was 59.3±18.3 years, and their mean APACHE II score was 21.8±14.0. The normal K+ group comprised 74 (46.3%) patients. The abnormal K+ group had a significantly higher mean APACHE II score, proportion of coronary artery disease, and rate of vasopressor treatment. An abnormal serum K+ level was associated with significantly higher ICU mortality and incidence of ventricular fibrillation. Conclusion Critically ill patients with abnormal K+ levels had a higher incidence of ventricular arrhythmia and ICU mortality than patients with normal K+ levels.

Background Published reports consistently describe incomplete delivery of prescribed enteral nutrition. Which specific step in the process delays or interferes with the administration of a full dose of nutrients is unclear. Objectives To assess factors associated with interruptions in enteral nutrition in critically ill patients receiving mechanical ventilation. Methods An observational prospective study of 59 consecutive patients who required mechanical ventilation and were receiving enteral nutrition was done in an 18-bed medical intensive care unit of an academic center. Data were collected prospectively on standardized forms. Steps involved in the feeding process from admission to discharge were recorded, each step was timed, and delivery of nutrition was quantified. Results Patients received approximately 50% (mean, 1106.3; SD, 885.9 Cal) of the prescribed caloric needs. Enteral nutrition was interrupted 27.3% of the available time. A mean of 1.13 interruptions occurred per patient per day; enteral nutrition was interrupted a mean of 6 (SD, 0.9) hours per patient each day. Prolonged interruptions were mainly associated with problems related to small-bore feeding tubes (25.5%), increased residual volumes (13.3%), weaning (11.7%), and other reasons (22.8%). Placement and confirmation of placement of the small-bore feeding tube were significant causes of incomplete delivery of nutrients on the day of admission. Conclusions Delivery of enteral nutrition in critically ill patients receiving mechanical ventilation is interrupted by practices embedded in the care of these patients. Evaluation of the process reveals areas to improve the delivery of enteral nutrition.

A Prospective Study

Introduction: Among critically ill patients presenting to Emergency Room (ER) of Tribhuwan University Teaching Hospital (TUTH), a number of patients have to either remain in ER or have to be referred outside due to unavailability of critical care beds. Studies have shown significant association between delayed admission and mortality rates along with increased length of stay and higher cost. This study aimed to present an audit of critically ill patients presenting to ER of TUTH. Methods: This was a prospective study conducted over a period of one month. All patients presenting to ER of TUTH were triaged and critically ill patients were shifted to Red area of the ER. All patients ≥16 years of age shifted to Red area during the study period were enrolled in our study. Results: Out of 3718 patients presenting to ER during the study period, the number of critically ill patients ≥16 years of age was 526 i.e. 14.14% of total patients. Among them, the common diagnosis were Cerebrovascular Accidents (CVA) followed by Intoxication, Acute Exacerbation (AE) of Chronic Obstructive Pulmonary Disease (COPD), Pneumonia and Chronic Kidney Disease (CKD) respectively. Almost 20% of these patients were admitted, 31% were referred and 40% were shifted for observation. The median length of ER stay was 6 hours (Mean: 8.5 hrs; Range: 20 min to 70 hr 15 min). Conclusion: Among critically ill patients presenting to our ER, almost 1/5th of the patients were admitted whereas more than 2/3rd were either referred or remained in our ER. This data highlights the need for solutions to provide optimal care for the acute phase management of the critically ill patients.
