A Narrative Review on the Administration of Inhaled Prostaglandins in Critically Ill Adult Patients With Acute Respiratory Distress Syndrome.

OBJECTIVE: To describe the effect of inhaled prostaglandins on both oxygenation and mortality in critically ill patients with acute respiratory distress syndrome (ARDS), with a focus on safety and efficacy in coronavirus disease 2019 (COVID-19)-associated ARDS and non-COVID-19 ARDS. DATA SOURCES: A literature search of MEDLINE was performed using the following search terms: inhaled prostaglandins, inhaled epoprostenol, inhaled nitric oxide, ARDS, critically ill. All abstracts were reviewed. STUDY SELECTION AND DATA EXTRACTION: Relevant English-language reports and studies conducted in humans between 1980 and June 2023 were considered. DATA SYNTHESIS: Data regarding inhaled prostaglandins and their effect on oxygenation are limited but show a benefit in patients who respond to therapy, and data pertaining to their effect on mortality is scarce. Concerns exist regarding the formulation of inhaled epoprostenol (iEPO) utilized in addition to modes of medication delivery; however, the limited data surrounding their use have shown a reasonable safety profile. Other avenues and beneficial effects may exist with inhaled prostaglandins, such as use in COVID-19-associated ARDS or non-COVID-19 ARDS patients undergoing noninvasive mechanical ventilation or during patient transport. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE: The use of inhaled prostaglandins can be considered in critically ill patients with COVID-19-associated ARDS or non-COVID-19 ARDS who are experiencing difficulties with oxygenation refractory to nonpharmacologic strategies. CONCLUSIONS: The use of iEPO and other inhaled prostaglandins requires further investigation to fully elucidate their effects on clinical outcomes, but it appears these medications may have a potential benefit in COVID-19-associated ARDS and non-COVID-19 ARDS patients with refractory hypoxemia but with little effect on mortality.

Evaluation of Goal Phenytoin Levels After an Initial Intravenous Loading Dose at an Academic Medical Center.

BACKGROUND: Phenytoin intravenous loading doses are administered in status epilepticus to rapidly achieve therapeutic levels. Accurately assessing phenytoin levels after the initial load can be challenging because of its complex pharmacokinetic profile and nonstandardized weight-based loading doses. OBJECTIVES: The objectives of this analysis were to determine the incidence of patients achieving goal phenytoin levels after the initial loading dose and characterize factors that contribute to achieving the goal level. METHODS: This single-center, retrospective cohort analysis was approved by our institutional review board and included adult patients who received a phenytoin load from May 2016 to March 2021. Patients were excluded if no total phenytoin level was drawn within 24 hours of the load, if the maintenance dose was given before the first level was drawn, or if the patient was on phenytoin before the load. The major endpoint was the percentage of patients achieving a corrected goal phenytoin level of ≥10 mcg/mL after the initial load. Multivariate regression was used to determine predictors of achieving the goal phenytoin level. RESULTS: Of the 152 patients included, 139 patients (91.4%) achieved a corrected goal level after the first load. Patients at goal received a significantly higher median weight-based loading dose (19.1 mg/kg [15.0-20.0] vs 12.6 mg/kg [10.1-15.0], P < 0.01). The multivariate analysis identified weight-based dosing as a statistically significant predictor of achieving the corrected goal level (odds ratio, 1.30; 95% CI, 1.12-1.53; P < 0.01). CONCLUSION AND RELEVANCE: Most patients achieved a corrected goal phenytoin level after the initial load. A higher median weight-based loading dose was shown to be a predictor of achieving the goal level and should be encouraged for rapid seizure termination. Future studies are warranted to confirm patient-specific factors that affect rapid achievement of the goal phenytoin level.

Safety of Intravenous Push Lacosamide Compared With Intravenous Piggyback at a Tertiary Academic Medical Center.

BACKGROUND: There are limited data regarding the incidence of adverse events associated with administering lacosamide by intravenous push (IVP) compared with IV piggyback (IVPB). OBJECTIVE: The objective of this analysis was to compare the safety profile, including cardiovascular effects, sedative effects, and IV site reactions of IVP and IVPB lacosamide administration. METHODS: A retrospective pre/post cohort analysis comparing patients who received lacosamide via IVP and IVPB was conducted. Safety end points included hypotension, bradycardia, medication-related sedation, and IV site reactions. The relationship between patient characteristics and the incidence of safety end points was analyzed using the Student t-test and χ2 test as appropriate. RESULTS: Bradycardia occurred after 0.19% of IVP administrations and 1.09% of IVPB administrations assessed (P = 0.07). Hypotension was observed in 3.16% of IVP administrations compared to 1.59% in the IVPB cohort (P = 0.12). Post lacosamide-related sedation was noted in 11.32% and 11.68% of the IVP and IVPB cohorts, respectively (P = 0.87). Infusion site reaction rates of 1.80% and 0.84% were documented in the IVP and IVPB cohorts, respectively (P = 0.33). Of note, only 1 adverse event required clinical intervention. One 200-mg dose in the IVP cohort required a fluid bolus postadministration. CONCLUSION AND RELEVANCE: IVP lacosamide was associated with a similar incidence of cardiovascular, neurological, and infusion site-related adverse events compared with IVPB, in which nearly every adverse event was deemed clinically insignificant. Lacosamide administered via IVP may be considered a safe alternative method of administration in the acute care setting.

The Effect of Concomitant Sirolimus and Propofol Therapy on Triglyceride Concentrations in Critically Ill Patients.

BACKGROUND: Sirolimus and propofol are both independently associated with the development of hypertriglyceridemia (HTG) during therapy. To date, there are no published reports describing synergistic or additive drug interaction resulting in HTG with concomitant use of these medications. STUDY QUESTION: To identify the occurrence of HTG in patients receiving concomitant sirolimus and propofol infusion therapy. METHODS: Adult patients receiving sirolimus and a continuous propofol infusion for at least 12 hours from January 2005 to August 2009 were retrospectively evaluated. Data included Acute Physiology and Chronic Health Evaluation II score, weight, length of propofol therapy, and baseline triglyceride (TG) concentrations. The major outcome was incidence of HTG (TGs ≥500 mg/dL). Minor outcomes included the change in TG concentration from therapy initiation and manifestations of propofol-related infusion syndrome (PRIS). RESULTS: Sixteen patients were included in the analysis, with 8 (50%) of the patients developing HTG. The patients in this case series had the following mean values: Acute Physiology and Chronic Health Evaluation II score of 20.2 ± 5.3, weight of 76.3 ± 21.2 kg, and baseline TG concentrations of 181.3 ± 89.7 mg/dL. Indications for sirolimus therapy included hematopoietic stem-cell transplantation (n = 15) and heart transplantation (n = 1). Mean length of propofol infusion was 99.8 ± 88.5 hours. The mean TG concentration during infusion was 515.6 ± 468.1 mg/dL. Fourteen (87.5%) patients had an increase of ≥100 mg/dL, 12 (75%) patients had an increase of ≥200 mg/dL, and 6 (37.5%) patients had an increase of ≥300 mg/dL in TG concentrations during therapy. Eleven patients developed one manifestation of PRIS, excluding HTG, and one patient had more than 2 new onset PRIS manifestations during propofol therapy. CONCLUSIONS: Coadministration of propofol and sirolimus can potentially result in HTG, which may warrant more frequent monitoring. Further analysis is needed to examine the mechanism and clinical impact of this interaction.

Clinical Practice Guidelines for the Prevention and Management of Pain, Agitation/Sedation, Delirium, Immobility, and Sleep Disruption in Adult Patients in the ICU.

OBJECTIVE: To update and expand the 2013 Clinical Practice Guidelines for the Management of Pain, Agitation, and Delirium in Adult Patients in the ICU. DESIGN: Thirty-two international experts, four methodologists, and four critical illness survivors met virtually at least monthly. All section groups gathered face-to-face at annual Society of Critical Care Medicine congresses; virtual connections included those unable to attend. A formal conflict of interest policy was developed a priori and enforced throughout the process. Teleconferences and electronic discussions among subgroups and whole panel were part of the guidelines' development. A general content review was completed face-to-face by all panel members in January 2017. METHODS: Content experts, methodologists, and ICU survivors were represented in each of the five sections of the guidelines: Pain, Agitation/sedation, Delirium, Immobility (mobilization/rehabilitation), and Sleep (disruption). Each section created Population, Intervention, Comparison, and Outcome, and nonactionable, descriptive questions based on perceived clinical relevance. The guideline group then voted their ranking, and patients prioritized their importance. For each Population, Intervention, Comparison, and Outcome question, sections searched the best available evidence, determined its quality, and formulated recommendations as "strong," "conditional," or "good" practice statements based on Grading of Recommendations Assessment, Development and Evaluation principles. In addition, evidence gaps and clinical caveats were explicitly identified. RESULTS: The Pain, Agitation/Sedation, Delirium, Immobility (mobilization/rehabilitation), and Sleep (disruption) panel issued 37 recommendations (three strong and 34 conditional), two good practice statements, and 32 ungraded, nonactionable statements. Three questions from the patient-centered prioritized question list remained without recommendation. CONCLUSIONS: We found substantial agreement among a large, interdisciplinary cohort of international experts regarding evidence supporting recommendations, and the remaining literature gaps in the assessment, prevention, and treatment of Pain, Agitation/sedation, Delirium, Immobility (mobilization/rehabilitation), and Sleep (disruption) in critically ill adults. Highlighting this evidence and the research needs will improve Pain, Agitation/sedation, Delirium, Immobility (mobilization/rehabilitation), and Sleep (disruption) management and provide the foundation for improved outcomes and science in this vulnerable population.

Etanercept for the Treatment of Transplantation-Related Lung Injury After Hematopoietic Stem Cell Transplantation.

Although some data suggest favorable outcomes with use of etanercept for treatment of transplantation-related lung injury, concerns, such as development of new infections, still exist. The objective of this study was to describe the usage of etanercept at our institution and to evaluate the efficacy and safety of etanercept for this indication. Adult patients receiving at least one dose of etanercept for the treatment of pulmonary complications in patients after hematopoietic stem cell transplant from January 2005 to December 2010 were retrospectively evaluated. Outcomes included hospital mortality, incidence of new infection after etanercept administration, and time from administration of first dose of etanercept to infection. Seventeen patients who received etanercept at our institution from January 2005 to December 2010 were included. Four patients (24%) survived their hospital stay, and 3 patients (18%) were alive at both 100 days and 1 year from the initiation of etanercept therapy. Four patients (24%) developed at least one confirmed new infection after the initiation of etanercept therapy. Both moderate and long-term survival in our cohort was low. Caution and careful assessment of the risks and benefits of therapy should be taken before initiation of etanercept for transplantation-related lung injury.

Intravenous Immune Globulin Stewardship Program at a Tertiary Academic Medical Center.

BACKGROUND: In October 2010, a pharmacist-driven stewardship program was implemented at the Brigham and Women's Hospital to ensure continued adherence to the prescribing guideline, focusing on indications for intravenous immune globulin (IVIG) use and dosing per ideal body weight. OBJECTIVE: The primary objective was to describe an IVIG stewardship program at a tertiary academic medical center. METHODS: This was a prospective, observational study from January 2013 through December 2014. All patients ordered to receive IVIG during the defined study period were included. The intervention assessed describes a pharmacist-driven IVIG stewardship program for medication approval. The primary end point was guideline compliance based on indication, dose, dosing weight, and frequency. Secondary end points included the number of patients receiving IVIG, indications, orders discontinued as a result of guideline nonadherence, and total amount dispensed. RESULTS: A total of 418 patients were identified during the study time frame. The top indications were: hypogammaglobulinemia in bone marrow transplantation and hematological malignancy (50.7%), acute solid organ rejection (11.8%), and immune thrombocytopenia with bleeding (10.1%). In all, 12 patients (2.9%) received IVIG for an indication nonadherent with the IVIG prescribing guideline; 9 patients (2.2%) and 2 patients (0.5%), respectively, received a different dose or frequency per the prescribed indication; and 12 orders (2.9%) for indications nonadherent to the guideline were discontinued. A total of 26 033 g of IVIG were dispensed during the study period. CONCLUSIONS: An IVIG stewardship program, including an institution-specific prescribing guideline and a pharmacist-driven stewardship program, may ensure guideline compliance for appropriateness of indication and dose at an academic medical center.

Implementation of a Prolonged Infusion Guideline for Time-Dependent Antimicrobial Agents at a Tertiary Academic Medical Center.

Administration of time-dependent beta-lactam antibiotic as a prolonged infusion may maximize the pharmacodynamic target of time above the minimum inhibitory concentration. We describe the implementation of a prolonged infusion at a tertiary academic medical center, and a 1-year compliance analysis with the guideline. After performing a thorough literature search, a guideline was developed by members of the Department of Infectious Diseases and Department of Pharmacy. Approval and endorsement of the guideline was obtained by the Antimicrobial Subcommittee and Pharmacy and Therapeutics Committee. Physical champions were instrumental in the implementation of the guideline institution-wide. We then performed a 1-year retrospective analysis of guideline compliance from January 1, 2011 to December 31, 2011. Noncompliant administrations were obtained from smart infusion pumps. The total number of doses administered was taken from pharmacy information resources. In total, nearly 85,000 time-dependent doses were administered. Compliance with the prolonged infusion guideline was 89%. Rates of compliance did not significantly differ between medications (P = 0.555). Obtaining support from key stakeholders in collateral services and institutional leadership was vital for the success of this guideline. Compliance with the guideline 1 year after implementation was high. Implementation of a prolonged infusion guideline is feasible with institutional support and motivation.

Clinical and Economic Impact of Formulary Conversion From Inhaled Flolan to Inhaled Veletri for Refractory Hypoxemia in Critically Ill Patients.

BACKGROUND: Flolan (iFLO) and Veletri (iVEL) are 2 inhaled epoprostenol formulations. There is no published literature comparing these formulations in critically ill patients with refractory hypoxemia. OBJECTIVE: To compare efficacy, safety, and cost outcomes in patients who received either iFLO or iVEL for hypoxic respiratory failure. METHODS: This was a retrospective, single-center analysis of adult, mechanically ventilated patients receiving iFLO or iVEL for improvement in oxygenation. The primary end point was the change in the PaO2/FiO2 ratio after 1 hour of pulmonary vasodilator therapy. Secondary end points assessed were intensive care unit (ICU) length of stay (LOS), hospital LOS, duration of study therapy, duration of mechanical ventilation, mortality, incidence of adverse events, and cost. RESULTS: A total of 104 patients were included (iFLO = 52; iVEL = 52). More iFLO patients had acute respiratory distress syndrome compared with the iVEL group (61.5 vs 34.6%; P = 0.01). There was no difference in the change in the PaO2/FiO2 ratio after 1 hour of therapy (33.04 ± 36.9 vs 31.47 ± 19.92; P = 0.54) in the iFLO and iVEL groups, respectively. Patients who received iVEL had a shorter duration of mechanical ventilation (P < 0.001) and ICU LOS (P < 0.001) but not hospital LOS (P = 0.86) and duration of therapy (P = 0.36). No adverse events were attributed to pulmonary vasodilator therapy, and there was no difference in cost. CONCLUSIONS: We found no difference between iFLO and iVEL when comparing the change in the PaO2/FiO2 ratio, safety, and cost in hypoxic, critically ill patients. There were differences in secondary outcomes, likely a result of differences in underlying indication for inhaled epoprostenol.

Utilization of a Pharmacy Clinical Surveillance System for Pharmacist Alerting and Communication at a Tertiary Academic Medical Center.

The objective of this analysis is to describe the utilization metrics of a pharmacy clinical surveillance system (PCSS) at a tertiary, academic medical center.We performed a retrospective database analysis assessing rule-based alerts (RBA), interventions and pharmacist communication notes documented in the PCSS from January 1, 2014 to December 31, 2014. Reports were generated on 92 unique RBAs sent to clinicians for evaluation. Metrics assessed included the number of RBAs that were triggered, clinically evaluated, intervened on by pharmacists, and therapeutic category of interventions. Pharmacy communication notes were also evaluated.A total of 399,979 RBAs were triggered through the PCSS. During that time, pharmacists documented a total of 17,733 interventions. The most common RBAs were related to lab abnormalities (132,487; 33 %) and anticoagulation/antiplatelet therapy (126,425; 32.1 %). Interventions were most frequently related to RBAs regarding anticoagulation/antiplatelet therapy (6412; 36 %) and antimicrobial therapy (3320; 19 %). Pharmacist communication was most commonly related to clarification of medication and lab orders, and therapeutic drug monitoring.Based on utilization metrics presented, the implementation of a PCSS has successfully generated RBAs to aid pharmacists in clinical practice and improved departmental documentation and communication. Further analysis is warranted to assess the impact of the RBAs, interventions, and communication notes on outcomes such as hospital cost and adverse drug events.

Evaluation of a Pharmacist-Directed Vancomycin Dosing and Monitoring Pilot Program at a Tertiary Academic Medical Center.

BACKGROUND: Consensus guidelines recommend vancomycin doses of 15 to 20 mg/kg every 8 to 12 hours in patients with normal renal function. OBJECTIVE: To evaluate the effect of a pharmacist-directed vancomycin dosing and monitoring pilot program on the percentage of patients receiving targeted weight-based dosing recommendations. METHODS: This was a pre-/postevaluation study, approved by the institutional review board at our institution, comparing retrospectively reviewed vancomycin dosing practices hospital-wide between September 1 and September 30, 2010 to patients prospectively managed by a pharmacist-directed vancomycin pilot program between February 1 and April 26, 2011. All adult inpatients receiving intravenous vancomycin were included, unless patients had a creatinine clearance less than or equal to 60 mL/min or indication for therapy was surgical prophylaxis or febrile neutropenia. The primary outcome was the percentage of patients who received optimal vancomycin dosing defined as ≥30 mg/kg/d within 24 hours of initiation of therapy. Secondary outcomes included number of pharmacist interventions, length of therapy and incidence of nephrotoxicity while receiving vancomycin. RESULTS: A total of 319 patients were analyzed, 161 preimplementation and 158 postimplementation. The percentage of patients who received optimal vancomycin dosing was significantly higher postimplementation of the pilot program, 96.8 versus 40.4% (P < 0.001). Pharmacist-directed interventions postimplementation, resulted in 50% more patients being dosed optimally (P < 0.001). Patients in the pilot program also had a shorter length of therapy (10.0 vs 8.4 days, P < 0.003) and a lower incidence of nephrotoxicity (8.7% vs 3.2%, P = 0.006). CONCLUSIONS: This pharmacist-directed vancomycin pilot program significantly increased the percentage of patients optimally dosed according to consensus guidelines within 24 hours of initiation of therapy.

Implementation of an Automated Dispensing Cabinet Stewardship Program at a Tertiary Academic Medical Center.

Automated dispensing cabinet (ADC) use within hospitals is designed to replace or partially replace medication cabinets or carts to allow for a more decentralized model of medication distribution. This project was designed to improve medication delivery by decreasing the burden of dispensing patient-specific medications from a centralized inpatient pharmacy while decreasing overall inventory cost. This single-center pilot analysis evaluated ADC inventory optimization in a mixed medical population. Data collected included inventory cost on ADC, medications removed from or added to ADC, patient-specific medications sent from central pharmacy, and the rate of medication stock outs on ADC.

Evaluation of an institution-wide guideline for hyperglycemic emergencies at a tertiary academic medical center.

BACKGROUND: No previous studies exist examining implementation of an institution-wide guideline and order set for hyperglycemic emergencies (diabetic ketoacidosis [DKA] and hyperosmolar hyperglycemic state [HHS]). OBJECTIVE: Evaluate the impact of an institutional guideline and order set for hyperglycemic emergencies. METHODS: This retrospective descriptive study evaluated patients with a diagnosis of DKA or HHS. Two time periods were evaluated: phase 1 (PRE) assessed practice preguideline implementation, and phase 2 (POST) assessed practice postguideline and order set introduction. RESULTS: A total of 172 patients (91 PRE and 81 POST) were included in the analysis. There was no difference in the mean hospital length of stay (LOS) in the PRE versus POST groups (5.2 ± 4 vs 5.9 ± 8.6 days, P = .49). The mean intensive care unit (ICU) LOS was shorter in the POST group (64.8 ± 19 vs 37.1 ± 74.8 hours, P < .01). The POST group had an increase in frequency of assessments for clearance of urinary ketones (18 vs 33.3%, P = .03) and ß-hydroxybutyrate (16 vs 37%, P < .01). Frequency of point-of-care glucose testing (12.5 ± 4.6 vs 15.1 ± 4.7, P < .01) and time to anion gap closure (13 ± 9 vs 9.3 ± 7.4 hours, P < .01) improved in the POST group. There was no difference in the number of patients experiencing hypoglycemia or hypokalemia between both groups. CONCLUSIONS: Implementation of an institutional guideline and order set for hyperglycemic emergencies decreased ICU LOS and time to anion gap closure, with no difference in rates of hypoglycemia.

Implementation of a dexmedetomidine stewardship program at a tertiary academic medical center.

BACKGROUND: Brigham and Women's Hospital implemented a dexmedetomidine stewardship program in October 2010 beginning with an institution-specific prescribing guideline. To ensure continued adherence to the prescribing guideline, a pharmacist-driven quality assurance program was implemented in November 2011. OBJECTIVE: The primary objective of this study is to describe the role and impact of a dexmedetomidine stewardship program on dexmedetomidine use at a tertiary academic medical center. METHODS: This is a prospective descriptive analysis of a dexmedetomidine stewardship program. Dexmedetomidine stewardship data were collected prospectively from January 2012 through June 2012, in all intensive care units (ICUs) at a single academic medical center. Adult patients (>18 years old) receiving dexmedetomidine therapy continuously for sedation and in the ICU were included in the analysis. RESULTS: A total of 99 patients were identified during the study time frame, during which 71 (71.7%) were identified as compliant with the institutional guideline. The total number of patients receiving dexmedetomidine for greater than 24 hours was 13 (13.1%), of whom 10 (76.9%) received targeted interventions; 15 (15.2%) targeted interventions were made on all patients receiving dexmedetomidine during the study time frame. The total use of dexmedetomidine during the study period was 1310 vials, compared with 5404 vials during the equivalent time frame in 2010-a 76% reduction. CONCLUSIONS: A dexmedetomidine stewardship program, including an institution-specific prescribing guideline and a pharmacist-driven quality assurance program may ensure guideline compliance and decreased use of dexmedetomidine at an academic medical center.

Safety of Intravenous Push Ertapenem Compared to Intravenous Piggyback at a Tertiary Academic Medical Center.

Background: Recent shortages of intravenous (IV) fluids have resulted in healthcare systems converting administration of many medications from IV piggyback (IVPB) to IV push (IVP). Administering medications via IVP presents numerous advantages; however, IV site reactions such as phlebitis and infiltration may occur. Objective: The objective of this analysis is to evaluate the infusion site safety of ertapenem given as peripheral IVP compared to IVPB in adult patients. Methods: This was an institutional review board-approved, single-center, retrospective study. Patients, ages 18 or older, receiving IV ertapenem were identified. The major endpoints analyzed were IV site reactions including phlebitis and infiltration. The Naranjo Nomogram was utilized to assess the causality of the reactions to determine the likelihood of whether the event was caused by the medication itself or other factors. Results: To date, 283 administrations (92 patients) in the IVP group and 319 administrations (82 patients) in the IVPB group were analyzed. There were 13 IV site reactions compared to 8 in the IVP vs IVPB group, respectively (P-value = 0.16). Ten of the events in the IVP group were deemed "possible" and 2 deemed "doubtful," while the remaining event was considered "probable" per the Naranjo Nomogram. Of the events in the IVPB group, all 8 were found to be "possible." Conclusion: The administration of IVP ertapenem showed comparable rates of infusion site reactions compared to IVPB. Implementation of IVP ertapenem appears to be associated with infusion site safety similar to IVPB and should be considered safe to administer.

Evaluation of Rocuronium Continuous Infusion in Critically Ill Patients During the COVID-19 Pandemic and Drug Shortages.

Background: Limited data exist to support the use of rocuronium continuous infusions in the intensive care unit (ICU). Objective: To evaluate the dosing and monitoring of adult patients who received rocuronium for hypoxemic respiratory failure during the Coronavirus Disease 2019 (COVID-19) pandemic. Methods: This was a retrospective, single-center study from March 1, 2020 to May 31, 2020. We identified all adult patients admitted to any ICU who received rocuronium via continuous infusion. Patients were excluded if they received rocuronium for <6 hours. The main outcome of this study was to determine the median rocuronium maintenance continuous infusion rate in the ICU. Secondary outcomes of this study included the initial continuous infusion rate, duration of therapy, cumulative dose, frequency and median of rocuronium boluses, time to resolution of neuromuscular blockade, and the relationship between the hourly administration rates of rocuronium and train-of-four (TOF) assessments. Results: Seventy-one patients and 97 paralytic infusions were included. Fifty-nine patients (83%) were positive for SARS CoV-2. Of the 97 rocuronium infusions, the median dose at initiation was 3 (3-5) mcg/kg/min and duration of infusion was 45 (23.6-92.5) hours. The median continuous infusion maintenance rate was 4.3 (2.8-7.2) mcg/kg/min. There was a negligible correlation between the dose of rocuronium and the TOF results (r = .04). A total of 1775 TOFs were assessed, of which 46.2% were over-paralyzed, 35.7% well-paralyzed, and 18.1% under-paralyzed. Conclusions: The initial and maintenance infusion doses in our analysis were lower than what have been previously referenced.

Practical approach to clinical controversies in glycemic control for hospitalized surgical patients.

The importance of glycemic management in surgical patient populations stems from an association between hyperglycemia and increased rates of surgical site infections, sepsis, and mortality. Various guidelines provide recommendations regarding target glucose concentrations, but all stress the importance of avoiding hypoglycemia as well. Within the surgical patient population, glycemic targets may vary further depending on the surgical service, such as cardiac surgery, neurosurgery, or reconstructive burn surgery. Glycemic management in critically ill surgical patients is achieved primarily through the use of intravenous insulin infusion protocols. These protocols can include fixed protocols, multiplication factor protocols, and computerized algorithms. In contrast, noncritically ill surgical patients are generally managed through the utilization of subcutaneous insulin with a combination of basal, bolus, and sliding scale insulin. Insulin protocols should be effective at maintaining glucose concentrations within the specified target range with minimal hypoglycemic events. Monitoring glucose concentrations while on either an intravenous or subcutaneous insulin protocol is essential. Point-of-care testing is the primary method for monitoring glucose concentrations in both critically ill and noncritically ill surgical patients and allows for adjustment of the insulin regimen. As patients move between units and to the outpatient setting, ensuring adequate follow-up is essential to maintaining control of hyperglycemia.
