Proctoclysis for rehydration in children - A scoping review and a pilot survey among medical doctors.

Although proctoclysis (enema) is a historically proven, safe and cost-effective rehydration method that needs little training for users and can effectively replace intravenous hydration in different care settings, it is an uncommon choice for hydration in children with fever and is often missing in official guidelines. To evaluate the usefulness of proctoclysis, this study provides a scoping review of the existing literature. The matched literature was labelled in 5 categories, identifying 6 indication fields that are emphasized in the literature on rectal rehydration. The analysis showed that proctoclysis is mostly used in the context of diagnostic procedures, constipation or in the treatment of a gastrointestinal disease. It is also described as a quick, safe and cost-effective intervention for fluid replacement in emergency, critical care or resource-scarce settings. There are also socio-cultural variations in its use Additionally, we performed a survey on attitudes and experience of medical doctors towards proctoclysis based on a semi-structured questionnaire. In the survey, we analysed the experience of 35 medical doctors from 8 countries. Although we found a general acceptance of enema as beneficial in both hospitalized patients and in home care, doctors expressed the need for more experience with enema and the need for more education materials in order to effectively perform the procedure. Based on our findings, we suggest that further research is necessary examining the attitude towards proctoclysis among parents, nurses and doctors. Enema can have a considerable clinical advantage during home care for gastroenteritis or other infectious diseases with fever to prevent insufficient oral fluid intake resulting in a negative fluid balance. Risks and safety issues are rare and should be considered. However, due to its low level of social acceptability in order to reduce refusal rate, more education is necessary for both medical providers and parents.

Application of Phenylephrine Combined with Goal-Directed Fluid Therapy in Elderly Patients Undergoing Hip Arthroplasty: A Randomized Controlled Trial.

Objective: To investigate the therapeutic effect of phenylephrine combined with goal-directed fluid therapy (GDFT) in elderly patients undergoing total hip arthroplasty. Methods: From June 2018 to May 2019, a total of 80 patients, age > 70 years, scheduled for total hip arthroplasty at Guangzhou Red Cross Hospital in China were consecutively included in this prospective randomized controlled trial. The patients were divided into 2 groups of 40 patients each by the random number table method. Patients in the control group were given GDFT alone, and patients in the experimental group were given phenylephrine combined with GDFT. The duration of surgery, blood loss, intraoperative urine output, and fluid input were analyzed. Heart rate (HR), mean arterial pressure (MAP), cardiac index (CI) and stroke volume variation (SVV) were compared in the 2 groups at different times: before surgery (T0), after induction (T1), before bone cement placement (T2), after bone cement placement (T3) and after surgery (T4). Lactate, oxygenation index and cerebral oxygen uptake rate were compared perioperatively. Meanwhile, the incidence of abdominal distension, nausea and vomiting, pulmonary infection and cognitive dysfunction within 7 days after surgery were compared. Results: The intraoperative fluid input in the experimental group was significantly lower than in the control group (P < .05). In T1 and T3, heart rate (HR) and stroke volume variability (SVV) in the control group were significantly higher than in the experimental group (P < .05), but mean arterial pressure (MAP) and cardiac index (CI) were significantly lower than in the experimental group (P < .05). The intraoperative lactic acid in the control group was significantly higher than in the experimental group (P < .05). In addition, we found that the intraoperative oxygenation index and the postsurgical oxygenation index in the control group decreased by 86.86% and 87.49%, respectively, compared with the preoperative values (P < .05). In addition, at T1 and T3, HR and SVV in the control group were significantly higher than T0 (P < .05), while MAP and CI were significantly lower than T0 (P < .05). In the experimental group, there was no significant difference in HR, SVV, MAP or CI at any time points compared with those of T0 (P < .05). The oxygenation index in the control group was lower than before surgery (P < .05). There was no significant difference in urine volume or brain oxygen uptake between the 2 groups (P < .05). Conclusion: Phenylephrine combined with GDFT can be used in elderly patients undergoing hip arthroplasty to reduce fluid input and improve intraoperative hemodynamic stability, to reduce the occurrence of postoperative related complications.

Order Substitutions and Education for Balanced Crystalloid Solution Use in an Integrated Health Care System and Association With Major Adverse Kidney Events.

Importance: Trials comparing balanced crystalloids with normal saline have yielded mixed results regarding reductions in kidney complications and mortality for hospitalized patients receiving intravenous fluids. Objective: To evaluate the association of a multifaceted implementation program encouraging the preferential use of lactated Ringer solution with patient outcomes and intravenous fluid-prescribing practices in a large, multilevel health care system. Design, Setting, and Participants: This type 2 hybrid implementation and comparative effectiveness study enrolled all patients 18 years or older who received 1 L or more of intravenous fluids while admitted to an emergency department and/or inpatient unit at 1 of 22 hospitals in Idaho and Utah between November 1, 2018, and February 29, 2020. An interrupted time series analysis was used to assess study outcomes before and after interventions to encourage use of lactated Ringer solution. Exposures: Implementation program combining order set modification, electronic order entry alerts, and sequential clinician-targeted education to encourage prescribing of lactated Ringer solution instead of normal saline. Main Outcomes and Measures: The primary implementation outcome was the patient-level proportion of intravenous fluids that was balanced crystalloids. The primary effectiveness outcome was the incidence of major adverse kidney events (MAKE30)-a composite of new persistent kidney dysfunction, new initiation of dialysis, and death-at 30 days. Results: Among 148 423 patients (median [IQR] age, 47 [30-67] years; 91 302 women [61%]), the proportion of total fluids received that was lactated Ringer solution increased from 28% to 75% in the first week vs the last week of the study (immediate implementation effect odds ratio [OR], 3.44; 95% CI, 2.79-4.24). The estimated MAKE30 absolute risk reduction was 2.2% (95% CI, 1.3%-3.3%) based on interrupted time series analysis showing a decrease in the week-on-week trend for MAKE30 (OR difference, 0.03; 95% CI, 0.03-0.03, P < .001). The immediate postimplementation OR for MAKE30 was 0.88 (95% CI, 0.76-1.01), with a decrease in persistent kidney dysfunction (OR, 0.80; 95% CI, 0.69-0.93) and mortality (OR, 0.78; 95% CI, 0.65-0.93) but not dialysis (OR, 1.00; 95% CI, 0.76-1.32). Conclusions and Relevance: In this comparative effectiveness study, an implementation program was associated with an increase in the proportion of fluids administered as lactated Ringer solution compared with normal saline and was associated with a reduction in MAKE30 events among patients treated in a large integrated health care system.

Pancreatitis in Children.

Pediatric pancreatitis describes a spectrum covering acute pancreatitis, acute recurrent pancreatitis, and chronic pancreatitis, each with varying clinical manifestations and risk factors requiring a tailored diagnostic approach. We emphasize management strategies based on age, risk factors, recurrence, and complications. A discussion of the role of therapeutic endoscopy is reviewed and highlights the growing role of endoscopic ultrasound and endoscopic retrograde cholangiopancreatography in children with pancreatitis. Particular diagnostic challenges in autoimmune pancreatitis are reviewed with an emphasis on differentiating this entity from alternate pancreaticobiliary pathologies. Finally, we explore a multidisciplinary approach to acute recurrent and chronic pancreatitis.

Caffeine-induced hypokalemia: a case report.

BACKGROUND: With an increase in the global popularity of coffee, caffeine is one of the most consumed ingredients of modern times. However, the consumption of massive amounts of caffeine can lead to severe hypokalemia. CASE PRESENTATION: A 29-year-old man without a specific past medical history was admitted to our hospital with recurrent episodes of sudden and severe lower-extremity weakness. Laboratory tests revealed low serum potassium concentration (2.6-2.9 mmol/L) and low urine osmolality (100-130 mOsm/kgH2O) in three such prior episodes. Urinary potassium/urinary creatinine ratio was 12 and 16 mmol/gCr, respectively. The patient was not under medication with laxatives, diuretics, or herbal remedies. Through an in-depth interview, we found that the patient consumed large amounts of caffeine-containing beverages daily, which included > 15 cups of coffee, soda, and various kinds of tea. After the cessation of coffee intake and concomitant intravenous potassium replacement, the symptoms rapidly resolved, and the serum potassium level normalized. CONCLUSIONS: An increased intracellular shift of potassium and increased loss of potassium in urine due to the diuretic action have been suggested to be the causes of caffeine-induced hypokalemia. In cases of recurring hypokalemia of unknown cause, high caffeine intake should be considered.

The impact of fluid resuscitation via colon on patients with severe acute pancreatitis.

Severe acute pancreatitis (SAP) is a life-threatening disease. Fluid Resuscitation Via Colon (FRVC) may be a complementary therapy for early controlled fluid resuscitation. But its clinical application has not been reported. This study aims to explore the impact of FRVC on SAP. All SAP patients with the first onset within 72 h admitted to the hospital were included from January 2014 to December 2018 through electronic databases of Ruijin hospital and were divided into FRVC group (n = 103) and non-FRVC group (n = 78). The clinical differences before and after the therapy between the two groups were analyzed. Of the 181 patients included in the analysis, the FRVC group received more fluid volume and reached the endpoint of blood volume expansion ahead of the non-FRVC group. After the early fluid resuscitation, the inflammation indicators in the FRVC group were lower. The rate of mechanical ventilation and the incidence of hypernatremia also decreased significantly. Using pure water for FRVC was more helpful to reduce hypernatremia. However, Kaplan-Meier 90-day survival between the two groups showed no difference. These results suggest that the combination of FRVC might benefit SAP patients in the early stage of fluid resuscitation, but there is no difference between the prognosis of SAP patients and that of conventional fluid resuscitation. Further prospective study is needed to evaluate the effect of FRVC on SAP patients.

Association of Positive Fluid Balance at Discharge After Sepsis Management With 30-Day Readmission.

Importance: Although early fluid administration has been shown to lower sepsis mortality, positive fluid balance has been associated with adverse outcomes. Little is known about associations in non-intensive care unit settings, with growing concern about readmission from excess fluid accumulation in patients with sepsis. Objective: To evaluate whether positive fluid balance among non-critically ill patients with sepsis was associated with increased readmission risk, including readmission for heart failure. Design, Setting, and Participants: This multicenter retrospective cohort study was conducted between January 1, 2012, and December 31, 2017, among 57 032 non-critically ill adults hospitalized for sepsis at 21 hospitals across Northern California. Kaiser Permanente Northern California is an integrated health care system with a community-based population of more than 4.4 million members. Statistical analysis was performed from January 1 to December 31, 2019. Exposures: Intake and output net fluid balance (I/O) measured daily and cumulatively at discharge (positive vs negative). Main Outcomes and Measures: The primary outcome was 30-day readmission. The secondary outcomes were readmission stratified by category and mortality after living discharge. Results: The cohort included 57 032 patients who were hospitalized for sepsis (28 779 women [50.5%]; mean [SD] age, 73.7 [15.5] years). Compared with patients with positive I/O (40 940 [71.8%]), those with negative I/O (16 092 [28.2%]) were older, with increased comorbidity, acute illness severity, preexisting heart failure or chronic kidney disease, diuretic use, and decreased fluid administration volume. During 30-day follow-up, 8719 patients (15.3%) were readmitted and 3639 patients (6.4%) died. There was no difference in readmission between patients with positive vs negative I/O (HR, 1.00; 95% CI, 0.95-1.05). No association was detected between readmission and I/O using continuous, splined, and quadratic function transformations. Positive I/O was associated with decreased heart failure-related readmission (HR, 0.80 [95% CI, 0.71-0.91]) and increased 30-day mortality (HR, 1.23 [95% CI, 1.15-1.31]). Conclusions and Relevance: In this large observational study of non-critically ill patients hospitalized with sepsis, there was no association between positive fluid balance at the time of discharge and readmission. However, these findings may have been limited by variable recording and documentation of fluid intake and output; additional studies are needed to examine the association of fluid status with outcomes in patients with sepsis to reduce readmission risk.

Rapid Weight Gain Following Weight Cutting in Male and Female Professional Mixed Martial Artists.

Rapid weight loss or "weight cutting" is a common but potentially harmful practice used in mixed martial arts competition. Following the official weigh-in, competitors refeed and rehydrate themselves in a process known as rapid weight gain (RWG) to realize a potential competitive advantage. While data from surveys and small series have indicated the majority of mixed martial arts athletes engage in rapid weight loss, there is a lack of officially collected data from sanctioning organizations describing its prevalence. The present investigation represents a summary of the data collected between December 2015 and January 2018 by the California State Athletic Commission. In total, 512 professional mixed martial artists (455 males and 57 females) were included. Of these, 503 (98%) athletes gained body mass between weigh-in and their bouts. Total RWG between weigh-in and competition was 5.5 ± 2.5 kg, corresponding to an 8.1% ± 3.6% body mass increase. Total RWG was 5.6 ± 2.5 kg (8.1% ± 3.6%) for males and 4.5 ± 2.3 kg (8.0% ± 3.8%) for females. More than one quarter of men and one third of women gained >10% body mass between weigh-in and competition. Athletes from leading international promotions gained more absolute, but not relative, body mass than those from regional promotions. Our findings indicate RWG is nearly ubiquitous in professional , with a similar prevalence in male and female athletes. Trends based on promotion suggest a larger magnitude of RWG in presumably more experienced and/or successful mixed martial artists from leading international promotions.

Acute Trimethyltin Poisoning Caused by Exposure to Polyvinyl Chloride Production: 8 Cases.

This manuscript aimed to describe and analyze acute trimethyltin poisoning caused by exposure to polyvinyl chloride production and review the literature. Combined with an analysis of occupational hygiene survey data, the clinical data of 8 cases of acute trimethyltin poisoning were analyzed retrospectively. The clinical manifestations of acute trimethyltin poisoning are mainly related to central nervous system damage, hypokalemia and metabolic acidosis in patients with severe poisoning. Early positive potassium supplementation and symptomatic treatment are beneficial to the improvement of the condition. The early recognition of central nervous system manifestations and hypokalemia is beneficial for early diagnosis and correct treatment.

The use of vasopressors during acute burn resuscitation.

BACKGROUND: Vasopressors may be required during acute burn resuscitation to support mean arterial blood pressure, but their use is not well-described in the burn literature. The purpose of this study was to examine vasopressor use during acute fluid resuscitation. METHODS: Retrospective review of adults with burns ≥ 20% TBSA admitted to an ABA-verified regional burn center. Patients administered an infusion of a vasopressor for at least 30 min during the 1 st 48 h post-burn formed the PRESSOR group while patients who did not receive vasopressors formed the NoPRESSOR group. RESULTS: We studied 52 burned adults, 85% of which had flame burns. Vasopressors were administered during resuscitation to 31% of patients. Vasopressor infusions began at 20.9 ± 10.9 h post burn and were continued for 16.8 ± 10.8 h. PRESSOR patients (N = 16) had significantly greater total (p = 0.001) and full thickness burn size (p < 0.001), and need for mechanical ventilation (p = 0.005) than NoPRESSOR patients (N = 36). PRESSOR and NoPRESSOR patients did not differ significantly in per cent predicted fluid volume received in the first 24 h (143 ± 58 Vs. 125 ± 46 respectively). PRESSOR patients compared to NoPRESSOR patients tended to have been administered 5% albumin (Alb) less often (38% Vs 47%) and high dose vitamin C (HDVC) more often during resuscitation (69% vs 17%). Multivariate regression analysis found that patient age (OR 1.189, 95% CI: 1.047, 1.351) and HDVC (OR 24.701, 95% CI: 1.558, 391.551) were independently associated with greater use of vasopressors. An inverse probability weighted propensity analysis also identified a significant association between HDVC and increased use of vasopressors (OR 6.902, 95 % CI: 2.503, 19.026), and significantly decreased vasopressor administration following Alb administration (OR 0.310, 95% CI: 0.130, 0.739). CONCLUSION: Advanced age appears to be the most important determinant of vasopressor use during resuscitation. While vasopressor requirements appear to have been increased by HDVC and decreased by Alb, this needs to be formally evaluated in a large randomized study.

Postural Tachycardia Syndrome: Nutrition Implications.

Postural tachycardia syndrome (POTS) is a syndrome characterized by elevated heart rate without hypotension and most commonly occurs in young females (generally <35 years of age). The prevalence of POTS is on the rise, but the etiology is still under investigation, and there appear to be multiple potential physiologic causes. The majority of these patients experience a multitude of gastrointestinal (GI) and systemic symptoms and conditions that may contribute to functional debility and poor quality of life. Although symptoms generally improve with age, they can still lead to significant issues meeting nutrition and hydration needs. This paper summarizes the understood potential pathophysiology of POTS, associated GI and nutrition issues, general treatment of POTS, and strategies to assess and meet the unique nutrition and hydration needs of these patients.

Beyond ventilatory support: challenges in general practice and in the treatment of critically Ill children and adolescents with SARS-CoV-2 infection.

Severe acute respiratory syndrome coronavirus 2 (Sars-CoV-2 infection) is a new challenge for all countries, and children are predisposed to acquire this disease. Some studies have demonstrated more severe diseases in adults, but critically ill pediatric patients have been described in all ages. Pulmonary involvement is the major feature, and ventilatory support is common in critical cases. Nevertheless, other very important therapeutic approaches must be considered. In this article, we reviewed extensively all recent medical literature to point out the main clinical attitudes to support these pediatric patients during their period in respiratory support. Radiologic findings, fluid therapy, hemodynamic support, use of inotropic/vasopressors, nutritional therapy, antiviral therapy, corticosteroids, antithrombotic therapy, and immunoglobulins are analyzed to guide all professionals during hospitalization. We emphasize the importance of a multi-professional approach for adequate recovery.

Nutritional Strategies to Optimize Performanceand Recovery in Rowing Athletes.

Rowing is a high-intensity sport requiring a high level of aerobic and anaerobic capacity. Although good nutrition is essential for successful performance in a rowing competition, its significance is not sufficiently established. This review aimed to provide nutritional strategies to optimize performance and recovery in rowing athletes based on a literature review. Following the guidelines given in the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA), we performed web searches using online databases (Pubmed, Web of Science, Wiley Online Library, ACS Publications, and SciFinder). Typically, a rowing competition involves a 6-8-min high-intensity exercise on a 2000-m course. The energy required for the exercise is supplied by muscle-stored glycogens, which are derived from carbohydrates. Therefore, rowing athletes can plan their carbohydrate consumption based on the intensity, duration, and type of training they undergo. For effective and safe performance enhancement, rowing athletes can take supplements such as ß-alanine, caffeine, ß-hydroxy-ß-methylbutyric acid (HMB), and beetroot juice (nitrate). An athlete may consume carbohydrate-rich foods or use a carbohydrate mouth rinse. Recovery nutrition is also very important to minimize the risk of injury or unexplained underperformance syndrome (UUPS) from overuse. It must take into account refueling (carbohydrate), rehydration (fluid), and repair (protein). As lightweight rowing athletes often attempt acute weight loss by limiting food and fluid intake to qualify for a competition, they require personalized nutritional strategies and plans based on factors such as their goals and environment. Training and competition performance can be maximized by including nutritional strategies in training plans.

Perioperative nutrition: Recommendations from the ESPEN expert group.

BACKGROUND & AIMS: Malnutrition has been recognized as a major risk factor for adverse postoperative outcomes. The ESPEN Symposium on perioperative nutrition was held in Nottingham, UK, on 14-15 October 2018 and the aims of this document were to highlight the scientific basis for the nutritional and metabolic management of surgical patients. METHODS: This paper represents the opinion of experts in this multidisciplinary field and those of a patient and caregiver, based on current evidence. It highlights the current state of the art. RESULTS: Surgical patients may present with varying degrees of malnutrition, sarcopenia, cachexia, obesity and myosteatosis. Preoperative optimization can help improve outcomes. Perioperative fluid therapy should aim at keeping the patient in as near zero fluid and electrolyte balance as possible. Similarly, glycemic control is especially important in those patients with poorly controlled diabetes, with a stepwise increase in the risk of infectious complications and mortality per increasing HbA1c. Immobilization can induce a decline in basal energy expenditure, reduced insulin sensitivity, anabolic resistance to protein nutrition and muscle strength, all of which impair clinical outcomes. There is a role for pharmaconutrition, pre-, pro- and syn-biotics, with the evidence being stronger in those undergoing surgery for gastrointestinal cancer. CONCLUSIONS: Nutritional assessment of the surgical patient together with the appropriate interventions to restore the energy deficit, avoid weight loss, preserve the gut microbiome and improve functional performance are all necessary components of the nutritional, metabolic and functional conditioning of the surgical patient.

Maintenance Fluid Therapy with Saline, Dextrose-Supplemented Saline or Lactated Ringer in Childhood: Short-Term Metabolic Effects.

Maintenance with isotonic fluids is recommended in children with gastroenteritis and failure of oral rehydration therapy. However, little is known on the short-term effects of the commonly prescribed intravenous solutions on metabolic balance in children. The aim of this study is to report on our experience with normal saline, dextrose-supplemented saline and lactated Ringer solution. METHODS: A retrospective analysis from the charts of all previously apparently healthy children with acute gastroenteritis, mild to moderate dehydration and failure of oral rehydration, evaluated between January 2016 and December 2019 at our institution, was performed. Subjects prescribed the above-mentioned maintenance intravenous fluids and with blood testing immediately before starting fluid therapy and 4-6 h later, were eligible. The changes in bicarbonate, ionized sodium, potassium, chloride, anion gap and glucose were investigated. Kruskal-Wallis test with the post-hoc Dunn's comparison and the Fisher exact test were applied. RESULTS: A total of 134 out of 732 children affected by acute gastroenteritis were included (56 patients were prescribed normal saline, 48 dextrose-supplemented normal saline and 30 lactated Ringer solution). The effect of the three solutions on sodium and potassium was similar. As compared to non-supplemented normal saline (+0.4 (-1.9 - +2.2) mmol/L), dextrose-supplemented normal saline (+1.5 (+0.1 - +4.2) mmol/L) and lactated Ringer (+2.6 (+0.4 - +4.1) mmol/L) solution had a positive effect on plasma bicarbonate. Finally, the influence of dextrose-supplemented saline on blood glucose was different (+1.1 (+0.3 - +2.2) mmol/L) compared to that observed in cases hydrated with non-supplemented saline (-0.4 (-1.2 - +0.3) mmol/L) or lactated Ringer solution (-0.4 (-1.2 - +0.1) mmol/L). CONCLUSIONS: This study points out that maintenance intravenous therapies using normal saline, dextrose-supplemented saline or lactated Ringer solution have different effects on metabolic balance. A personalized fluid therapy that takes into account the clinical and biochemical variables is advised.

Efficacy of Furosemide, Oral Sodium Chloride, and Fluid Restriction for Treatment of Syndrome of Inappropriate Antidiuresis (SIAD): An Open-label Randomized Controlled Study (The EFFUSE-FLUID Trial).

RATIONALE & OBJECTIVE: First-line therapy for syndrome of inappropriate antidiuresis (SIAD) is fluid restriction. Additional treatment for patients who do not respond to fluid restriction are water restriction with furosemide or water restriction with furosemide and salt supplementation. However, the efficacy of these treatments has never been tested in a randomized controlled study. The objective of this study was to investigate whether, combined with fluid restriction, furosemide with or without sodium chloride (NaCl) supplementation was more effective than fluid restriction alone in the treatment of hyponatremia in SIAD. STUDY DESIGN: Open-label randomized controlled study. SETTING & PARTICIPANTS: Patients with serum sodium concentrations ([Na+]) ≤ 130mmol/L due to SIAD. INTERVENTION(S): Random assignment to 1 of 3 groups: fluid restriction alone (FR), fluid restriction and furosemide (FR+FM), or fluid restriction, furosemide, and NaCl (FR+FM+NaCl). Strictness of fluid restriction (<1,000 or<500mL/d) was guided by the urine to serum electrolyte ratio. Furosemide dosage was 20 to 40mg/d. NaCl supplements were 3g/d. All treatments were continued for 28 days. OUTCOMES: The primary outcome was change in [Na+] at days 4, 7, 14, and 28 after randomization. RESULTS: 92 patients were recruited (FR, n=31; FR+FM, n=30; FR+FM+NaCl, n=31). Baseline [Na+] was 125±4mmol/L, and there were no significant differences between groups. Mean [Na+] on day 4 in all treatment groups was significantly increased from baseline by 5mmol/L (P<0.001); however, the change in [Na+] was not significantly different across groups (P=0.7). There was no significant difference in percentage of patients or time to reach [Na+] ≥ 130 or≥135mmol/L across the 3 groups. Acute kidney injury and hypokalemia (potassium≤3.0mmol/L) were more common in patients receiving furosemide. LIMITATIONS: Open-label treatment. CONCLUSIONS: In patients with SIAD, furosemide with NaCl supplement in combination with fluid restriction did not show benefits in correction of [Na+] compared with treatment with fluid restriction alone. Incidences of acute kidney injury and hypokalemia were increased in patients receiving furosemide. FUNDING: None. TRIAL REGISTRATION: Registered at the Thai Clinical Trial Registry with study number TCTR20170629004.

Blood and fluid management during scoliosis surgery: a single-center retrospective analysis.

AIM: In the present retrospective study in scoliosis surgery, we hypothesized that application of a protocol for blood and fluid management, based on goal-directed fluid therapy, cell salvage and tranexamic acid, could lead to reduced allogeneic red blood cells transfusion. METHODS AND MATERIAL: Thirty-five patients, with American Society of Anesthesiologists physical status I/III, between 14 and 18 years scheduled for elective orthopedic surgery of scoliosis, with a planned intensive care unit admission, were enrolled in a retrospective observational study. Patients were divided in two groups. Patients in no-protocol group (Group noPro, n = 18) received a liberal intraoperative fluid therapy and patients in protocol group (Group Pro, n = 17) received fluid therapy managed according to a stroke volume variation-based protocol. The protocol included fluid therapy according to SVV monitor, permissive hypotension, tranexamic acid infusion, restrictive RBC trigger and use of perioperative cell savage. STATISTICAL ANALYSIS USED: Student's t test (2-tailed), Mann-Whitney test, Chi square test were used for statistical analysis of the data. RESULTS: There were no significant differences between the two groups in demographic data and clinical characteristics. Infused crystalloids (p = .003) and transfused allogeneic red blood cells (p = .015) were lesser in Group Pro compared to Group noPro. On the other hand, diuresis (p < .001) and vasopressors administration (p = .042) were higher in Group Pro than in Group noPro. CONCLUSION: The application of a protocol for blood and fluid management, based on goal-directed fluid therapy, cell salvage and tranexamic acid, was associated with less crystalloid fluid administration, less perioperative RBC transfusions and significantly better diuresis than patients in the no-protocol group in scoliosis surgery. REGISTRATION NUMBER: ClinicalTrials.gov Identifier: NCT03814239.

Comparison of cisplatin-induced nephrotoxicity when using conventional versus short hydration in gastric cancer-a retrospective study.

Although a short hydration protocol for cisplatin has been recently developed for use in lung cancer, this has yet to be established for gastric cancer. This study reviewed medical records of patients with gastric cancer who received XPT(capecitabine/cisplatin/trastuzumab) therapy containing cisplatin. Patients received either the conventional or short hydration regimen. Nephrotoxicity was compared between these two regimens by monitoring the serum creatinine. Out of the 26 total patients, 19 received the conventional regimen while 7 received the short hydration regimen. There was a higher nephrotoxicity was observed in the group receiving the conventional regimen (42.1%, 8/19) as compared to the short hydration regimen (0%, 0/7). There was a statistically significant difference in nephrotoxicity between the regimens (P = 0.039). Study results suggest that short hydration may be a feasible regimen for XPT therapy in gastric cancer patients.

Safety, Efficacy, and Timeliness of Intravenous Potassium Chloride Replacement Protocols in a Pediatric Cardiothoracic Intensive Care Unit.

OBJECTIVE: Hypokalemia in children following cardiac surgery occurs frequently, placing them at risk of life-threatening arrhythmias. However, renal insufficiency after cardiopulmonary bypass warrants careful administration of potassium (K+). Two different nurse-driven protocols (high dose and tiered dosing) were implemented to identify an optimal K+ replacement regimen, compared to an historical low-dose protocol. Our objective was to evaluate the safety, efficacy, and timeliness of these protocols. DESIGN: A retrospective cohort review of pediatric patients placed on intravenous K+ replacement protocols over 1 year was used to determine efficacy and safety of the protocols. A prospective single-blinded review of K+ repletion was used to determine timeliness. PATIENTS: Pediatric patients with congenital or acquired cardiac disease. SETTING: Twenty-four-bed cardiothoracic intensive care unit in a tertiary children's hospital. INTERVENTIONS: Efficacy was defined as fewer supplemental potassium chloride (KCl) doses, as well as a higher protocol to total doses ratio per patient. Safety was defined as a lower percentage of serum K+ levels ≥4.8 mEq/L after a dose of KCl. Between-group differences were assessed by nonparametric univariate analysis. RESULTS: There were 138 patients with a median age of 3.0 (interquartile range: 0.23-10.0) months. The incidence of K+ levels ≥4.8 mEq/L after a protocol dose was higher in the high-dose protocol versus the tiered-dosing protocol but not different between the low-dose and tiered-dosing protocols (high dose = 2.2% vs tiered dosing = 0.5%, P = .05). The ratio of protocol doses to total doses per patient was lower in the low-dose protocol compared to the tiered-dosing protocol (P < .05). Protocol doses were administered 45 minutes faster (P < .001). CONCLUSION: The tiered-dosed, nurse-driven K+ replacement protocol was associated with decreased supplemental K+ doses without increased risk of hyperkalemia, administering doses faster than individually ordered doses; the protocol was effective, safe, and timely in the treatment of hypokalemia in pediatric patients after cardiac surgery.

Beyond ventilatory support: challenges in general practice and in the treatment of critically Ill children and adolescents with SARS-CoV-2 infection

SUMMARY Severe acute respiratory syndrome coronavirus 2 (Sars-CoV-2 infection) is a new challenge for all countries, and children are predisposed to acquire this disease. Some studies have demonstrated more severe diseases in adults, but critically ill pediatric patients have been described in all ages. Pulmonary involvement is the major feature, and ventilatory support is common in critical cases. Nevertheless, other very important therapeutic approaches must be considered. In this article, we reviewed extensively all recent medical literature to point out the main clinical attitudes to support these pediatric patients during their period in respiratory support. Radiologic findings, fluid therapy, hemodynamic support, use of inotropic/vasopressors, nutritional therapy, antiviral therapy, corticosteroids, antithrombotic therapy, and immunoglobulins are analyzed to guide all professionals during hospitalization. We emphasize the importance of a multi-professional approach for adequate recovery.

RESUMO A síndrome respiratória aguda grave (SRAG) pelo novo coronavirus (SARS-CoV-2) é um novo desafio para todos os países e crianças estão predispostas a adquirir a doença. Alguns estudos demonstraram quadros mais graves em adultos, mas crianças criticamente doentes foram descritas em todas as idades. O envolvimento pulmonar é a principal característica e a necessidade de suporte ventilatório é comum nos casos mais graves. Entretanto, outras abordagens terapêuticas importantes devem ser consideradas. Nesse artigo revisamos extensamente a literature médica até o momento a fim de citar os principais recursos terapêuticos para o manejo dos pacientes pediátricos durante o período de suporte ventilatório. Achados radiológicos, terapia fluídica, terapia antiviral, o uso de corticosteroides, terapia antitrombótica e o uso de imunoglobulinas foram analisados a fim de guiar os profissionais durante o período de hospitalização desses pacientes. Nós reforçamos a importância de uma abordagem multiprofissional para recuperação adequada.
