Human albumin and starch administration in critically ill patients: A prospective randomized clinical trial

OBJECTIVE: To determine whether intravenous infusion of either human albumin or hydroxyethyl-starch (HES) in hypo-albuminemic critically ill may lead to an increase in colloid osmotic pressure and to a better clinical outcome, i.e. lower mortality and fewer complications, compared to fluid replacement with normal saline. DESIGN: Prospective, randomized controlled clinical trial during 72 hours in 61 consecutively admitted severely ill patients. Randomisation took place by sealed envelope, kept outside of the hospital. SETTING: Intensive care unit of the Twenteborg Hospital, Almelo, The Netherlands. SUBJECTS: Sixty-three severely ill, hypo-albuminemic patients were selected; 27 patients had severe sepsis and 36 were post-surgical patients with SIRS. Two patients died shortly after randomization, 15 patients received human albumin, 15 HES 500 and 15 HES 1000 ml, and 16 saline. INTERVENTIONS: The patients were randomized to receive 300 ml human albumin (20%) per day, or 1000 ml normal saline per day, or 500 ml or 1000 ml HES per day, all for 72 hours. MAIN OUTCOME MEASURES: The primary outcome was plasma colloid osmotic pressure (COP). Secondary endpoints were fluid balance and the development of pulmonary edema. RESULTS: Administration of human albumin was effective in raising COP (P<0.001 on day 2 and day 3, compared to saline and HES). Neither fluid balances nor the development of peripheral or pulmonary edema were different between the groups. Mortality as well as length of stay at ICU were slightly higher in the group receiving human albumin, although not statistically significant. CONCLUSION: Raising colloid osmotic pressure with human albumin in hypoalbuminemic patients is not associated with improvement of the clinical outcome.     

Resuscitation of critically ill patients based on the results of gastric tonometry: a prospective, randomized, controlled trial

OBJECTIVE: To determine whether additional therapy aimed at correcting low gastric intramucosal pH (pHi) improves outcome in conventionally resuscitated, critically ill patients. DESIGN: Prospective, randomized, controlled study. SETTING: General intensive care unit (ICU) of a university teaching hospital. PATIENTS: A total of 210 adult patients, with a median Acute Physiology and Chronic Health Evaluation II score of 24 (range, 8-51). INTERVENTIONS: All patients were resuscitated according to standard guidelines. After resuscitation, those patients in the intervention group with a pHi of <7.35 were treated with additional colloid and then dobutamine (5 microg/kg/min then 10 microg/kg min) until 24 hrs after enrollment. MEASUREMENTS AND MAIN RESULTS: There were no significant differences (p > .05) in ICU mortality (39.6% in the control group vs. 38.5% in the intervention group), hospital mortality (45.3% in the control group vs. 42.3% in the intervention group), and 30-day mortality (43.7% in the control group vs. 40.2 in the intervention group); survival curves; median modified maximal multiorgan dysfunction score (10 points in the control group vs. 13 points in the intervention group); median modified duration of ICU stay (12 days in the control group vs. 11.5 days in the intervention group); or median modified duration of hospital stay (60 days in the control group vs. 42 days in the intervention group). A subgroup analysis of those patients with gastric mucosal pH of > or =7.35 at admission revealed no difference in ICU mortality (10.3% in the control group vs. 14.8% in the intervention group), hospital mortality (13.8% in the control group vs. 29.6% in the intervention group), or 30-day mortality (10.3% in the control group vs. 26.9% in the intervention group). CONCLUSIONS: The routine use of treatment titrated against pHi in the management of critically ill patients cannot be supported. Failure to improve outcome may be caused by an inability to produce a clinically significant change in pHi or because pHi is simply a marker of disease rather than a factor in the pathogenesis of multiorgan failure.     

A prospective, randomized study comparing percutaneous with surgical tracheostomy in critically ill patients

OBJECTIVE: To determine the relative cost-effectiveness of percutaneous dilational tracheostomy (PDT) and surgical tracheostomy (ST) in critically ill patients. DESIGN: Prospective randomized study. SETTING: Medical, surgical, and coronary intensive care units at Barnes-Jewish Hospital, a tertiary care medical center. PATIENTS: Eighty critically ill mechanically ventilated patients requiring elective tracheostomy. INTERVENTIONS: Randomization to either PDT performed in the intensive care unit or ST performed in the operating room. MEASUREMENTS AND MAIN RESULTS: Treatment groups were well matched with respect to age (PDT, 65.44 +/- 2.82 [mean +/- se] years; ST, 61.4 +/- 2.89 years, p = Ns), gender (PDT, 45% males; ST, 47.5% males, p = NS), severity of illness (Acute Physiology and Chronic Health Evaluation II score: PDT, 16.87 +/- 0.84; ST, 17.88 +/- 0.92, p = NS), and principle diagnosis. PDT was performed more quickly (PDT, 20.1 +/- 2.0 mins; ST, 41.7 +/- 3.9 mins, p < .0001) and was associated with lower patient charges than ST (total patient charges: PDT, 1,569 dollars +/- 157 dollars vs. ST, 3,172 dollars +/- 114 dollars; equipment/supply charges: PDT, 688 dollars +/- 103 dollars vs. ST, 1,526 dollars +/- 87 dollars; professional charges: PDT, 880 dollars +/- 54 dollars vs. ST, 1,647 dollars +/- 50 dollars; p < .0001 for all). There were no differences in days intubated before tracheostomy (PDT, 12.7 +/- 1.1 days; ST, 15.6 +/- 1.9, p = .20), intensive care unit length of stay (PDT, 24.5 +/- 2.5 days; ST, 28.5 +/- 3.1 days, p = .33), or hospital length of stay (PDT 49.7 +/- 4.2 days; ST, 43.7 +/- 3.5 days, p = .28) when we compared these two techniques. CONCLUSIONS: PDT is a cost-effective alternative to ST. The reduction in patient charges associated with PDT in this study resulted from the procedure being performed in the intensive care unit, thus eliminating the need for operating room facilities and personnel. PDT may become the procedure of choice for electively establishing tracheostomy in the appropriately selected patient who requires long-term mechanical ventilation.

The impact of frailty in critically ill patients after trauma: A prospective observational study

BackgroundAs our population ages, older adults are increasingly exposed to trauma. Frailty could be a useful measure to identify patients at risk of a poor outcome. This study aimed to determine the impact of frailty in an Australian trauma intensive care unit (ICU) population.MethodsA prospective observational study of critically ill trauma patients ≥50 years of age. Frailty was determined on admission to the ICU using the frailty phenotype. Demographic and hospital data were collected, and patients were followed up at 6 and 12 months. The primary outcome was 12-month mortality, and multiple regression was used to determine associated factors.ResultsOne hundred thirty-eight patients were included, whose mean age was 68 years; 78.2% (108/138) were classified as major trauma (Injury Severity Score >12). Twenty-two percent (30/138) of patients were identified as frail. Patients with frailty were significantly older: however, they were less severely injured and required lower rates of surgical interventions and mechanical ventilation. Frailty was independently associated with mortality at 6 and 12 months (odds ratio: 5.9, 95% confidence interval: 1.9–18.1 and odds ratio: 7.3, 95% confidence interval: 2.5–21.9, respectively). Patients with frailty had lower measures of global functioning (Glasgow Outcome Scale-Extended frail 3 [1–5] vs nonfrail 6 [(5–7], p = 0.002) and health status (Euro Qol 5Q-5D-5L utility score 0.6 [0.5–0.7] vs 0.7 [0.6–0.9], p = 0.02) at 12 months than patients without frailty.ConclusionFrailty is a useful predictor of poor outcomes in critically ill trauma patients.Registration of protocol numberACTRN12615000039583.     

A randomized clinical trial comparing ranitidine and antacids in critically ill patients

In a randomized trial of gastric pH control for stress ulcer prophylaxis, 200 mg/day ranitidine iv was compared to antacids in 86 patients admitted to an ICU. Six (15%) patients receiving ranitidine and six (13%) given antacids failed to maintain greater than 50% of the hourly gastric pH measurements at or above 4. Increasing the ranitidine dosage to 300 mg/day did not provide additional control. One patient in the antacid group developed an overt upper GI bleed secondary to endoscopically proven erosive disease. We conclude that iv ranitidine in a dosage of 200 mg/day is as effective as antacids in reducing gastric acidity and preventing stress ulcer disease in critically ill patients.     

Polyneuropathies in critically ill patients: A prospective evaluation

Objective To determine the incidence, severity and course of polyneuropathies in patients with sepsis or systemic inflammatory response syndrome combined with multiple organ failure.Design Prospective study.Setting Division of Intensive Care Medicine of the Department of Anesthesiology and Intessive Care and Intensive Care Unit of the Department of Neurology, University Hospital Innsbruck, Austria.Patients Twenty-two patients between 23 and 77 years old with sepsis or systemic inflammatory response syndrome combined with multiple organ failure fulfilling strict inclusion and exclusion criteria.Interventions Clinical neurologic examination and electromyography/nerve conduction velocity measurements during the stay on the Intensive Care Unit and 2–3 months later.Measurements and results In 9 of the 22 patients signs of polyneuropathy were found at the initial clinical investigation and in 7 patients at the follow-up investigation. Electrophysiologic investigation revealed signs of polyneuropathy in 18 patients initially and in 11 patients 2–3 months later.Conclusion In our patient population the frequency of the development of polyneuropathy was high (81.8%). Electrophysiologic investigation is superior to clinical neurologic examination in the detection of polyneuropathies.     

Guidelines for the inter- and intrahospital transport of critically ill patients

OBJECTIVE: The development of practice guidelines for the conduct of intra- and interhospital transport of the critically ill patient. DATA SOURCE: Expert opinion and a search of Index Medicus from January 1986 through October 2001 provided the basis for these guidelines. A task force of experts in the field of patient transport provided personal experience and expert opinion. STUDY SELECTION AND DATA EXTRACTION: Several prospective and clinical outcome studies were found. However, much of the published data comes from retrospective reviews and anecdotal reports. Experience and consensus opinion form the basis of much of these guidelines. RESULTS OF DATA SYNTHESIS: Each hospital should have a formalized plan for intra- and interhospital transport that addresses a) pretransport coordination and communication; b) transport personnel; c) transport equipment; d) monitoring during transport; and e) documentation. The transport plan should be developed by a multidisciplinary team and should be evaluated and refined regularly using a standard quality improvement process. CONCLUSION: The transport of critically ill patients carries inherent risks. These guidelines promote measures to ensure safe patient transport. Although both intra- and interhospital transport must comply with regulations, we believe that patient safety is enhanced during transport by establishing an organized, efficient process supported by appropriate equipment and personnel.     

Percutaneous tracheostomy in critically ill patients: a prospective, randomized comparison of two techniques

OBJECTIVE: To prospectively compare two commonly used methods for percutaneous dilational tracheostomy (PDT) in critically ill patients. DESIGN: Prospective, randomized, clinical trial. SETTING: Trauma and general intensive care units of a university tertiary teaching hospital, which is also a level 1 trauma center. PATIENTS: One hundred critically ill patients with an indication for PDT. INTERVENTIONS: PDT with the Ciaglia technique using the Ciaglia PDT introducer set and the Griggs technique using a Griggs PDT kit and guidewire dilating forceps. MEASUREMENTS AND MAIN RESULTS: Surgical time, difficulties, and surgical and anesthesia complications were measured at 0-2 hrs, 24 hrs, and 7 days postprocedure. Groups were well matched, and there were no differences between the two methods in surgical time or in anesthesia complications. Major bleeding complications were 4.4 times more frequent with the Griggs PDT kit. With the Ciaglia PDT kit, both intraoperative and at 2 and 24 hrs, surgical complications were less common (p = .023) and the procedure was more often completed without expert assistance (p = .013). Tracheostomy bleeding was not associated with either anticoagulant therapy or an abnormal clotting profile. Multivariate analysis identified the predictors of PDT complications as the Griggs PDT kit (p = .027) and the Acute Physiology and Chronic Health Evaluation (APACHE) II score (p = .041). The significant predictors of time required to complete PDT were the APACHE II score (p = .041), a less experienced operator (p = .0001), and a female patient (p = .013). CONCLUSIONS: Patients experiencing PDT with the Ciaglia PDT kit had a lower surgical complication rate (2% vs. 25%), less operative and postoperative bleeding, and less overall technical difficulties than did patients undergoing PDT with the Griggs PDT kit. Ciaglia PDT is, therefore, the preferred technique for percutaneous tracheostomy in critically ill patients.     

Adjudicating ventilator-associated pneumonia in a randomized trial of critically ill patients

The purpose of this study was to evaluate an adjudication strategy for diagnosing ventilator-associated pneumonia (VAP) in a randomized trial.

In a double-blind trial of sucralfate versus ranitidine, one of four pairs of adjudicators examined each case of clinically suspected VAP Nurse and physician notes and all relevant laboratory data were allocated to each adjudication pair in groups of five patients. Each reader in the pair decided whether the patient had VAP; differences were resolved by consensus discussion.

The overall unadjusted study odds ratio for VAP was 0.82 (P = .21) representing a trend toward less pneumonia with sucralfate compared with ranitidine. The odds ratio adjusted for adjudication pair was 0.85 (P = .27). The proportion of charts adjudicated as VAP positive among pairs ranged from 50% to 92%; crude agreement between readers in each pair varied from 50% to 82%. When adjudicators disagreed, the final consensus was split evenly between the two adjudicators' initial opinions in two pairs; in the other two pairs, the final decision reflected one dominant initial opinion. Personnel time to adjudicate all patients with a suspicion of VAP was 74 days.

Though adjudication of outcomes such as VAP is time-consuming, consistent decision-making rewuires strict criteria, training, and calibration. Patients should be assigned to adjudication teams through random allocation.     

High-protein hypocaloric vs normocaloric enteral nutrition in critically ill patients: A randomized clinical trial

PurposeAppropriate caloric intake in critically ill patients receiving enteral nutrition is controversial. This study evaluates the impact of different caloric regimens on severity of organ failure measured with Sequential Organ Failure Assessment (SOFA).Materials and methodsWe conducted a randomized prospective controlled trial. Study population included adult intensive care unit (ICU) patients expected to require enteral nutrition for more than 96 hours. Goals in the intervention group were hypocaloric (15 kcal/kg per day) enteral nutrition compared to normocaloric (25 kcal/kg per day) enteral nutrition, both with hyperproteic intake (1.7 g of protein/kg per day). Primary end point was change in SOFA score (ΔSOFA) from baseline at 48 hours. Secondary end points were ΔSOFA at 96 hours, insulin requirements, hyperglycemia or hypoglycemic episodes, length of ICU stay, days on ventilator, and 28-day mortality.ResultsAfter screening 443 patients, 120 patients were analyzed. There were no differences between groups in baseline characteristics. We did not find a statistically significant difference in ΔSOFA at 48 hours. Patients in the hypocaloric group showed lower average daily insulin requirements and percentage of patients requiring any insulin.ConclusionsHyperproteic, hypocaloric nutrition did not show different outcomes compared to normocaloric nutrition, except lower insulin requirements. Hypocaloric nutrition could provide a more physiologic approach with lower need for care and metabolic impact.     

Albumin administration improves organ function in critically ill hypoalbuminemic patients: A prospective, randomized, controlled, pilot study

OBJECTIVE: To test the hypothesis that administration of albumin to correct hypoalbuminemia might have beneficial effects on organ function in a mixed population of critically ill patients. DESIGN:: Prospective, controlled, randomized study. SETTING: Thirty-one-bed, mixed medicosurgical department of intensive care. PATIENTS: All adult patients with a serum albumin concentration < or =30 g/L were assessed for eligibility. Principal exclusion criteria were expected length of stay <72 hrs, life expectancy <3 months or a do-not-resuscitate order, albumin administration in the preceding 24 hrs, or evidence of fluid overload. INTERVENTIONS: The 100 patients were randomized to receive 300 mL of 20% albumin solution on the first day, then 200 mL/day provided their serum albumin concentration was <31 g/dL (albumin group), or to receive no albumin (control group). MEASUREMENTS AND MAIN RESULTS: The primary outcome was the effect of albumin administration on organ function as assessed by a delta Sequential Organ Failure Assessment score from day 1 to day 7 (or the day of intensive care discharge or death, whichever came first). The two groups of 50 patients were comparable at baseline for age, gender, albumin concentration, and Acute Physiology and Chronic Health Evaluation II score. Albumin concentration did not change over time in the control group but increased consistently in the albumin group (p < .001). Organ function improved more in the albumin than in the control group (p = .026), mainly due to a difference in respiratory, cardiovascular, and central nervous system components of the Sequential Organ Failure Assessment score. Diuretic use was identical in both groups, but mean fluid gain was almost three times higher in the control group (1679 +/- 1156 vs. 658 +/- 1101 mL, p = .04). Median daily calorie intake was higher in the albumin than in the control group (1122 [935-1158] vs. 760 [571-1077] kcal, p = .05). CONCLUSIONS: Albumin administration may improve organ function in hypoalbuminemic critically ill patients. It results in a less positive fluid balance and a better tolerance to enteral feeding.     

Prevention of colonization and infection in critically ill patients: a prospective randomized study

In a prospective randomized study to determine whether prevention of colonization of Gram-negative bacteria results in prevention of Gram-negative bacterial infections, 96 intensive care patients were randomly allocated into a control group and a study group. The study group received oral nonabsorbable antimicrobial agents (i.e., tobramycin, amphotericin B, and polymyxin E) in addition to parenteral antibiotics. Colonization with Gram-negative microorganisms in the oropharynx, and respiratory and digestive tracts increased in the control group during their stay, while the study group did not tend to colonize with Gram-negative bacteria. In the control group, 107 nosocomial infections were diagnosed, vs. 42 nosocomial infections in the study group. Nosocomial infections caused by Gram-negative bacteria were significantly less frequent in the study group. Mortality due to an acquired infection was significantly less frequent in the study group. We conclude that colonization, infection, and subsequent mortality by nosocomial Gram-negative bacteria can be prevented by a regime of topically applied nonabsorbable antibiotics.     

Microbial cell preparation in enteral feeding in critically ill patients: A randomized,double-blind,placebo-controlled clinical trial

Gut failure is a common condition in critically ill patients in the intensive care unit (ICU). Enteral feeding is usually the first line of choice for nutrition support in critically ill patients. However, enteral feeding has its own set of complications such as alterations in gut transit time and composition of gut eco-culture. The primary aim of this study was to investigate the effect of microbial cell preparation on the return of gut function, white blood cell count, C-reactive protein levels, number of days on mechanical ventilation, and length of stay in ICU. A consecutive cohort of 60 patients admitted to the ICU in University Malaya Medical Centre requiring enteral feeding were prospectively randomized to receive either treatment (n = 30) or placebo (n = 30). Patients receiving enteral feeding supplemented with a course of treatment achieved a faster return of gut function and required shorter duration of mechanical ventilation and shorter length of stay in the ICU. However, inflammatory markers did not show any significant change in the pretreatment and posttreatment groups. Overall, it can be concluded that microbial cell preparation enhances gut function and the overall clinical outcome of critically ill patients receiving enteral feeding in the ICU.
