Pharmacokinetics and pharmacodynamics of intravenously and subcutaneously administered pantoprazole in sheep (Ovis aries).

Abomasal ulcers are recognized in sheep of all ages, but research regarding therapeutic interventions is limited. Proton Pump Inhibitors (PPIs) such as pantoprazole, are clinically used with a paucity of evidence regarding efficacy in mature sheep. Intravenous and subcutaneously administered pantoprazole dosed at 1.0 mg/kg in adult sheep will increase the pH of abomasal fluid compared to pre-administration baseline. The objectives were to assess the effect of pantoprazole, after single and multiple administration, on abomasal fluid pH in adult sheep. A third objective was to describe the pharmacokinetic parameters of IV and SC pantoprazole. Four clinically healthy adult Southdown ewes previously fitted with a gastrostomy tube in the abomasum were utilized in this randomized, 2-way cross-over trial. Ewes received pantoprazole (1.0 mg/kg) as a single and 3-dose regimen (every 24 hours). After a 10 day washout period the reverse treatment was applied. Blood for analysis of pantoprazole concentration was collected intermittently for 24 hours, and abomasal fluid pH was measured at intervals for a 96-hour period. The pH of the abomasal fluid was higher in pantoprazole treatments for up to 24 hours after dosing. Following intravenous administration of pantoprazole to study ewes, elimination half-life, volume of distribution, and clearance of pantoprazole was estimated as 3.29 hours, 0.35 L/kg, and 65.26 mL/hr/kg respectively. After subcutaneous dosing, maximum concentration, time to maximum concentration, half-life of elimination, and volume of distribution, were estimated as 2604 ng/mL, 0.55 hours, 2.48 hours, and 0.37 L/kg. Additionally, the bioavailability was estimated as 83.33%. Pantoprazole administered IV or SC may be useful for treatment or prevention of abomasal ulcers in adult sheep.

[Therapeutic effect of intravenous thrombolysis with tenecteplase on patients with post awakening branch atheromatous disease].

Objective: To investigate the efficacy and safety of intravenous thrombolysis with Tenecteplase (TNK) in patients with post-awakening branch atheromatous disease (BAD). Methods: A retrospective collection was conducted on 178 patients with post-awakening BAD admitted to the Stroke Centre of Zhengzhou People's Hospital from January 2017 to June 2023, who had a mismatch in DWI/FLAIR on magnetic resonance imaging. The patients were divided into thrombolysis group (60 patients) and control group (118 patients) according to whether or not they were applied to intravenous thrombolysis by TNK. Propensity score matching (PSM) was used to pair and balance the confounding factors at 1∶1 between the two groups, and the 90-d long-term prognosis of the patients was assessed using the modified Rankin Scale (mRS) and the Barthel Index (BI). The National Institutes of Health Stroke Scale (NIHSS) score was used to compare the early neurological changes between the two groups.The differences in clinical outcomes were compared between the two groups. Results: Fifty-two pairs of patients, 65 males and 39 females, aged (60±9) years, were successfully matched by PSM. The thrombolysis group had lower NIHSS score than that of the control group at 24 h, 7 d, 14 d after treatment or at discharge [3(2, 5) vs 4(3, 7), 3(2, 5) vs 4(3, 5), and 2(1, 4) vs 3(2, 4)], and shorter hospital stay than that of the control group [9(7, 12) d vs 11(9, 13) d], and at the same time, the thrombolysis group was less likely to experience early neurological deterioration (END) [9.6% (5/52) vs 28.9% (15/52)], and the proportion of 90 d mRS≤1, mRS≤2, and BI scores were higher than those in the control group [63.5% (33/52) vs 30.8% (16/52), 82.7% (43/52) vs 59.6% (31/52), and (91±8) points vs (82±8) points ], all differences were statistically significant (P<0.05). The percentage of mRS≥4 points was higher in the control group than that in the thrombolysis group [23.1% (12/52) vs 7.7% (4/52)]. One case of intracranial haemorrhage occurred in the thrombolysis group, and 1 case in the control group died of pulmonary infection within 90 d of follow-up, with a case-fatality rate of 1.9% (1/52). Conclusion: In the patients with post-awakening BAD screened by MRI, TNK intravenous thrombolysis can significantly reduce the risk of END, improving long-term prognosis and has a high safety.

Intravenous Odatroltide for Acute Ischemic Stroke Within 24 Hours of Onset: A Phase 2, Multicenter, Randomized, Double-Blind, Placebo-Controlled Study.

Purpose: Odatroltide (LT3001), a novel small synthetic peptide molecule designed to recanalize occluded blood vessels and reduce reperfusion injury, is safe and efficacious in multiple embolic stroke animal models. This study aimed to investigate the safety and tolerability of intravenous administration of odatroltide in patients with acute ischemic stroke within 24 hours of onset. Patients and Methods: Patients with National Institutes of Health Stroke Scale (NIHSS 4-30) who were untreated with intravenous thrombolysis or endovascular thrombectomy were randomized (2:1) to receive a single dose of odatroltide (0.025 mg/kg) or placebo within 24 hours of stroke symptom onset. The primary safety outcome was symptomatic intracranial hemorrhage (sICH) occurrence within 36 hours. Results: Twenty-four patients were enrolled and randomized; of these 16 and 8 received intravenous odatroltide infusion and placebo, respectively. sICH did not occur in both groups, and other safety measures were comparable between the groups. The rate of excellent functional outcome (modified Rankin Scale score, 0-1, at 90 days) was 21% and 14% in the odatroltide and placebo groups, respectively. Furthermore, 47% and 14% of patients in the odatroltide and placebo groups, respectively, showed major neurological improvement (NIHSS improvement ≥4 points from baseline to 30 days). Among the 9 odatroltide-treated patients with baseline NIHSS ≥6, 78% showed major neurological improvement. Conclusion: Compared with placebo, treatment with intravenous odatroltide within 24 hours following onset of ischemic stroke appears to be safe and may be associated with better neurological and functional outcomes. However, the efficacy and safety of odatroltide requires further confirmation in the next phase of clinical trials. Clinical Trial Registration: Clinicaltrials.gov identifier: NCT04091945.

Investigating clinical pharmacokinetics of brivaracetam by using a pharmacokinetic modeling approach.

The development of technology and the processing speed of computing machines have facilitated the evaluation of advanced pharmacokinetic (PK) models, making modeling processes simple and faster. The present model aims to analyze the PK of brivaracetam (BRV) in healthy and diseased populations. A comprehensive literature review was conducted to incorporate the BRV plasma concentration data and its input parameters into PK-Sim software, leading to the creation of intravenous (IV) and oral models for both populations. The developed physiologically based pharmacokinetic (PBPK) model of BRV was then assessed using the visual predictive checks, mean observed/predicted ratios (Robs/pre), and average fold error for PK parameters including the maximum systemic concentration (Cmax), the area under the curve at time 0 to t (AUC0-∞), and drug clearance (CL). The PBPK model of BRV demonstrated that mean Robs/pre ratios of the PK parameters remained within the acceptable limits when assessed against a twofold error margin. Furthermore, model predictions were carried out to assess how AUC0-∞ is affected following the administration of BRV in individuals with varying degrees of liver cirrhosis, ranging from different child-pugh (CP) scores like A, B, and C. Moreover, dose adjustments were recommended by considering the variations in Cmax and CL in various kidney disease stages (mild to severe).

The hemostatic and anti-inflammatory effects of intravenous single-dose of tranexamic acid in double-segment posterior lumbar interbody fusion: a case control study.

This study aims to observe the hemostatic and anti-inflammatory effects of intravenous administration of tranexamic acid (TXA) in dual segment posterior lumbar interbody fusion (PLIF). The data of 53 patients with lumbar disease treated with double-segment PLIF were included in this study. The observation group was received a single-dose intravenous of TXA (1 g/100 mL) 15 min before skin incision after general anesthesia. The control group was not received TXA. The observation indicators included postoperative activated partial prothrombin time (APTT), thrombin time (PT), thrombin time (TT), fibrinogen (FIB), platelets (PLT), and postoperative deep vein thrombosis in the lower limbs, surgical time, intraoperative bleeding volume, postoperative drainage volume, transfusion rate, postoperative hospital stay, red blood cell (RBC), hemoglobin (HB), hematocrit (HCT), C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR) on the 1st, 4th, 7th, and last tested day after surgery. All patients successfully completed the operation, and there was no deep vein thrombosis after operation. There was no statistically significant difference in postoperative APTT, PT, TT, FIB, PLT, surgical time, and postoperative hospital stay between the two groups (p > 0.05). The intraoperative bleeding volume, postoperative drainage volume, and transfusion rate in the observation group were lower than those in the control group, and the differences were statistically significant (p < 0.05). There was no statistically significant difference in RBC, HB, HCT, CRP, and ESR between the two groups on the 1st, 4th, 7th, and last tested day after surgery (p > 0.05). Intravenous administration of TXA in dual segment PLIF does not affect coagulation function and can reduce bleeding volume, postoperative drainage volume, and transfusion rate. Moreover, it does not affect the postoperative inflammatory response.

Effects of intravenous inflammasome inhibitor (NuSepin) on suppression of proinflammatory cytokines release induced by cardiopulmonary bypass in swine model: a pilot study.

The systemic inflammatory response syndrome can occur due to an inflammatory reaction to the release of cytokines, and it has been linked to the circulation of pro- and anti-inflammatory cytokines. The cardiopulmonary bypass (CPB) system is known to activate numerous inflammatory pathways. Applying CPB in large animals for an extended period may be useful as a controlled experimental model for systemic inflammatory responses. The authors hypothesized that 0.2 mg/kg NuSepin® would inhibit CBP-induced proinflammatory cytokine release, and attenuate CPB-induced vasoplegia. CPB was maintained for 2 h in 8 male Yorkshire pigs. Ten ml of saline was administered intravenously to the control group, while the study group received 10 ml of NuSepin® (0.2 mg/kg), before start of CPB. Blood samples were collected at four different time points to evaluating the level of cytokine (TNF-α, IL-1ß, IL-6, IL-8) release during and after CBP. All vital signals were recorded as continuous waveforms using the vital recorder®. Our study demonstrated that IL-6 increased in both groups during CPB remained unchanged. However, in the Nusepin group, IL-6 levels rapidly decreased when CPB was stopped and the proinflammatory reaction subsided. Furthermore, the dose of norepinephrine required to maintain a mean pressure of 60 mmHg was also lower in the Nusepin group.

Intravenous fluid therapy in hospitalized adult dengue patients without shock: Impact on subsequent severe dengue and potential adverse effects.

There is a lack of evidence on the optimal administration of intravenous (IV) fluids in hospitalized adult dengue patients without compensated and hypotensive shock. This study utilized a well-established cohort of dengue patients to compare risks of progressing to severe dengue (SD) over time for patients who were administered IV fluid versus others who were not. We included adult patients (n = 4781) who were hospitalized for dengue infection from 2005 to 2008. Cases were patients who developed SD (n = 689) and controls were patients who did not up until discharge (n = 4092). We estimated the hazard ratios (HRs) and risk of SD over time between groups administered different volumes of IV fluids versus the no IV fluid comparison group using Cox models with time-dependent covariates. The doubly-robust estimation approach was used to control for the propensity of fluid administration given clinical characteristics of patients. Subgroup analyses by age, sex, and dengue warning signs before IV fluid administration were conducted. High (>2000 mL/day) IV fluids volume was associated with a higher risk of development of SD for those who had warning signs (HR: 1.77 [1.05-2.97], p: 0.0713) and for those below 55 years old (HR: 1.53 [1.04-2.25], p: 0.0713). Low (<1000 mL/day) IV fluids volume was protective against SD for patients without warning signs (HR: 0.757 [0.578-0.990], p: 0.0883), no lethargy (HR: 0.770 [0.600-0.998], p: 0.0847), and females (HR: 0.711 [0.516-0.980], p: 0.0804). Over the course of hospitalization, there were no significant differences in IV fluid administration and SD risk in most subgroups, except in those who experienced lethargy and were administered IV fluid volume or quantity. Administering high volumes of IV fluids may be associated with an increased risk of SD during hospitalization for adult dengue patients without shock. Judicious use of IV fluids as supportive therapy is warranted.

Improving management of intravenous maintenance fluids in the emergency department of a university hospital.

OBJECTIVE: Intravenous (IV) fluid therapy is a known source of iatrogenic complications. Guideline implementation can be used to educate and guide physicians on adequate fluid management. In the emergency department (ED), a complex and interruption-driven environment, workload is high and active documentation is required to facilitate audits of fluid management quality. PATIENTS AND METHODS: Fluid management was evaluated in the ED records of adult non-critically ill patients admitted to a tertiary care center before (PRE: 1/12/2016-31/3/2017) and after (POST: 1/12/2018-31/3/2019) implementation of an educational intervention aiming to optimize IV fluid therapy in November 2018. First, the appropriateness of the 24-hour IV maintenance fluid prescription was evaluated, as prescribed by the emergency physician. Second, factors associated with appropriate prescribing were assessed, as well as the quality of fluid management documentation practice. Prescription appropriateness and documentation quality were evaluated retrospectively using a structured audit instrument and additional review by experts. RESULTS: A total of 237 patients (2.3%) were included in the PRE-intervention group and 253 patients (2.4%) in the POST-intervention group. The expert panel evaluated 214 prescriptions in 82.3% of patients (PRE: 99, POST: 115), and appropriateness increased significantly (19.2% vs. 61.2%, p=0.002). A higher odds of an appropriate IV maintenance fluid prescription was determined, attributed to the intervention (adjOR=2.580; 95% CI 1.363-4.884) and in patients having a prehospital intervention (adjOR=1.914, 95% CI 1.022-3.586). Appropriateness of fluid management documentation did not significantly improve after the implementation of the intervention (15.6% vs. 16.2%, p=0.858). CONCLUSIONS: The IV fluid prescriptions' appropriateness was significantly higher after guideline implementation. However, documentation quality of fluid management was poor in the studied ED records. Active stewardship programs are warranted to further monitor fluid management quality in the ED.

Nonhealing Surgical Wounds in a Patient with Plasminogen Deficiency Type 1 Successfully Treated with Intravenous Plasminogen: A Case Report.

ABSTRACT: Intravenous plasminogen replacement therapy for patients with plasminogen deficiency type 1 (hypoplasminogenemia) was recently approved for marketing in the US. In this case report, the authors describe a 33-year-old man with hypoplasminogenemia who developed nonhealing postsurgical wounds following trauma to his right hand despite receiving standard treatment for 4 months. The patient was enrolled in a compassionate-use protocol with intravenous plasminogen replacement therapy and experienced prompt resolution of surgical wounds. He was the first human patient to receive replacement therapy with plasminogen, human-tvmh in the US and first to demonstrate cutaneous wound healing in addition to resolution of ligneous lesions attributable to plasminogen deficiency type 1.

Pharmacokinetics and Tissue Distribution of Itampolin A following Intragastric and Intravenous Administration in Rats Using Ultra-High-Performance Liquid Chromatography-Tandem Mass Spectrometry.

Itampolin A, a natural brominated tyrosine alkaloid isolated from the sponge Iotrochota purpurea, has been shown to have good inhibitory effects in lung cancer cells as a p38α inhibitor. A simple, sensitive, and reliable ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) method has been established, validated, and applied to the study of the pharmacokinetics and tissue distribution of itampolin A following intragastric and intravenous administration. Itampolin A and theophylline (internal standard, IS) were extracted by the simple protein precipitation technique using methanol as the precipitating solvent. Chromatographic separation was achieved by using the optimized mobile phase of a 0.1% formic acid aqueous solution and acetonitrile in the gradient elution mode. Itampolin A and IS were detected and quantified using positive electrospray ionization in the multiple reaction monitoring mode with transitions of m/z 863.9 → 569.1 for itampolin A and m/z 181.1 → 124.1 for IS, respectively. The assay exhibited a linear dynamic range of 1-1600 ng/mL for itampolin A in biological samples and the low limit of quantification was 1 ng/mL. Non-compartmental pharmacokinetic parameters indicated that itampolin A was well-absorbed into the systemic circulation and rapidly eliminated after administration. The apparent distribution volume of itampolin A was much higher after intragastric administration than that after intravenous administration. A tissue distribution study showed that itampolin A could be detected in different tissues and maintained a high concentration in the lung, which provided a material basis for its effective application in lung cancer. The pharmacokinetic process and tissue distribution characteristics of imtapolin A were expounded in this study, which can provide beneficial information for the further research and clinical application of itampolin A.

Magnesium sulfate for postoperative pain in orthopedic surgery: A narrative review.

Magnesium Sulfate (MgSO4) is a widely used adjuvant in anesthesia. Often administered with local anesthetics, it is known to reduce analgesic and opioid consumption while extending the duration of analgesia. MgSO4 applications extend to orthopedic surgeries, cardiovascular and urogenital procedures, offering extended postoperative pain relief. While commonly administered through various routes, there is a research gap concerning the comparative efficacy of intrathecal (IT) and intravenous (IV) MgSO4 administration. This narrative review aims to provide a comparison between IT and IV administration of MgSO4 particularly following orthopedic procedures, where pain management is paramount. A comprehensive literature search was conducted across several electronic databases, trial registries, and gray literature from inception to 2023. Inclusion criteria encompassed studies investigating the effects of perioperative IT administration of magnesium compared to perioperative IV administration of MgSO4 in patients undergoing surgery, with no language restrictions. Our search identified 4326 articles, of which 9 randomized controlled trials met our inclusion criteria. We summarized these selected articles. Four studies discussed IT magnesium sulfate (MgSO4) administration, 2 focused on IT administration in orthopedic surgeries, and 3 explored both IV and IT administration of MgSO4 in orthopedic surgery. IT MgSO4 shows promise in postoperative pain management, delaying block onset and extending duration. Personalized administration choice, considering patient factors and surgery type, is crucial. Further research is needed to refine strategies for better patient outcomes, particularly following orthopedic surgeries.

Intravenous Opioid Administration During Mechanical Ventilation and Use After Hospital Discharge.

Importance: Guidelines recommend an analgesia-first strategy for sedation during mechanical ventilation, but associations between opioids provided during mechanical ventilation and posthospitalization opioid-related outcomes are unclear. Objective: To evaluate associations between an intravenous opioid dose received during mechanical ventilation and postdischarge opioid-related outcomes in medical (nonsurgical) patients. Design, Setting, and Participants: This retrospective cohort study evaluated adults receiving mechanical ventilation lasting 24 hours or more for acute respiratory failure and surviving hospitalization. Participants from 21 Kaiser Permanente Northern California hospitals from January 1, 2012, to December 31, 2019, were included. Data were analyzed from October 1, 2020, to October 31, 2023. Exposures: Terciles of median daily intravenous fentanyl equivalents during mechanical ventilation. Main Outcomes and Measures: The primary outcome was the first filled opioid prescription in 1 year after discharge. Secondary outcomes included persistent opioid use and opioid-associated complications. Secondary analyses tested for interaction between opioid doses during mechanical ventilation, prior opioid use, and posthospitalization opioid use. Estimates were based on multivariable-adjusted time-to-event analyses, with death as a competing risk, and censored for hospice or palliative care referral, rehospitalization with receipt of opioid, or loss of Kaiser Permanente plan membership. Results: The study included 6746 patients across 21 hospitals (median age, 67 years [IQR, 57-76 years]; 53.0% male). Of the participants, 3114 (46.2%) filled an opioid prescription in the year prior to admission. The median daily fentanyl equivalent during mechanical ventilation was 200 µg (IQR, 40-1000 µg), with terciles of 0 to 67 µg, more than 67 to 700 µg, and more than 700 µg. Compared with patients who did not receive opioids during mechanical ventilation (n = 1013), a higher daily opioid dose was associated with opioid prescriptions in the year after discharge (n = 2942 outcomes; tercile 1: adjusted hazard ratio [AHR], 1.00 [95% CI, 0.85-1.17], tercile 2: AHR, 1.20 [95% CI, 1.03-1.40], and tercile 3: AHR, 1.25 [95% CI, 1.07-1.47]). Higher doses of opioids during mechanical ventilation were also associated with persistent opioid use after hospitalization (n = 1410 outcomes; tercile 3 vs no opioids: odds ratio, 1.44 [95% CI, 1.14-1.83]). No interaction was observed between opioid dose during mechanical ventilation, prior opioid use, and posthospitalization opioid use. Conclusions and Relevance: In this retrospective cohort study of patients receiving mechanical ventilation, opioids administered during mechanical ventilation were associated with opioid prescriptions following hospital discharge. Additional studies to evaluate risks and benefits of strategies using lower opioid doses are warranted.

Prospective observational study of peripheral intravenous cannula utilisation and frequency of intravenous fluid delivery in the emergency department-Convenience or necessity?

BACKGROUND: Peripheral Intravenous Cannulas (PIVCs) are frequently utilised in the Emergency Department (ED) for delivery of medication and phlebotomy. They are associated with complications and have an associated cost to departmental resources. A growing body of international research suggests many of the PIVCs inserted in the ED are unnecessary. METHODS: The objective of this study was to determine the rates of PIVC insertion and use. This was a prospective observational study conducted in one UK ED and one Italian ED. Adult ED patients with non-immediate triage categories were included over a period of three weeks in the UK ED in August 2016 and two weeks in the Italian ED in March and August 2017. Episodes of PIVC insertion and data on PIVC utilisation in adults were recorded. PIVC use was classified as necessary, unnecessary or unused. The proportion of unnecessary and unused PIVCs was calculated. PIVCs were defined as unnecessary if they were either used for phlebotomy only, or solely for IV fluids in patients that could have potentially been hydrated orally (determined against a priori defined criteria). PIVC classified as unused were not used for any purpose. RESULTS: A total of 1,618 patients were included amongst which 977 PIVCs were inserted. Of the 977 PIVCs, 413 (42%) were necessary, 536 (55%) were unnecessary, and 28 (3%) were unused. Of the unnecessary PIVCs, 473 (48%) were used solely for phlebotomy and 63 (6%) were used for IV fluids in patients that could drink. CONCLUSIONS: More than half of PIVCs placed in the ED were unnecessary in this study. This suggests that clinical decision making about the benefits and risks of PIVC insertion is not being performed on an individual basis.

[Acute poisoning with antiseptic of external application containing chlorohexidine in the case of accidental intravenous administration causing serious harm to health]. / Ostroe otravlenie antiseptikom naruzhnogo primeneniya khlorgeksidinom pri sluchainom vnutrivennom vvedenii s prichineniem tyazhkogo vreda zdorov'yu.

The article presents a case of expert evaluation of poisoning with chlorohexidine in the case of intravenous administration to a maternity woman who entered the maternity department for a planned cesarean section, contrary to the instructions for the use of this antiseptic, intended only for external or cavity application. The toxic effect of chlorohexidine began with thoracic discomfort, shortness of breath, then deep hypoxic phenomena in the form of diffuse cyanosis of the skin, facial pastoralism, respiratory disorders requiring ventilation, acute decrease of oxygen saturation in the blood up to 77% with further decrease to 60%, a pattern of pronounced hemorrhagic edema in the lungs, occurred when consciousness was absent. The consequences of poisoning are assessed as life-threatening from the forensic medical position, and uterus removal to prevent a heavy atonic hemorrhage is considered as loss of the organ. These features are characterized as causing serious harm to health. The legal evaluation of the health workers' actions is the prerogative of the juridical investigative authorities.

Intravenous ibuprofen versus ketorolac for perioperative pain control in open abdominal hysterectomy: a randomized controlled trial.

BACKGROUND: We aimed to compare the analgesic effects of intravenous ibuprofen to ketorolac after open abdominal hysterectomy. METHODS: This randomized double-blinded controlled trial included adult women scheduled for elective open abdominal hysterectomy. Participants were randomized to receive either 30 mg ketorolac (n = 50) or 800 mg ibuprofen (n = 50) preoperatively, then every 8 h postoperatively for 24 h. All participants received paracetamol 1 gm/6 h. Rescue analgesic was given if the visual analogue scale (VAS) for pain assessment was > 3. The primary outcome was the mean postoperative dynamic VAS during the first 24 h. Secondary outcomes were static VAS, intraoperative fentanyl consumption, postoperative morphine consumption, time to independent movement, and patient's satisfaction. RESULTS: Forty-six patients in the ibuprofen group and fifty patients in the ketorolac group were analyzed. The 24-h dynamic and static VAS were similar in the two groups. The median (quartiles) dynamic VAS was 1.1 (0.9, 1.9) in the ibuprofen group versus 1.0 (0.7, 1.3) in the ketorolac group, P-value = 0.116; and the median (quartiles) static VAS was 0.9 (0.6, 1.3) in the ibuprofen group versus 0.7 (0.4, 1.1) in the ketorolac group, P-value = 0.113. The intra- and postoperative analgesic requirements were also similar in the two groups. However, patient satisfaction was slightly higher in the ketorolac group than that in the ibuprofen group (median [quartiles]: 6 [5, 7] versus 5 [4, 7], respectively), P-value: 0.009. CONCLUSION: The two drugs, intravenous ibuprofen and ketorolac produced similar analgesic profile in patients undergoing open abdominal hysterectomy receiving multimodal analgesic regimen.

Intravenous Iron Repletion for Patients With Heart Failure and Iron Deficiency: JACC State-of-the-Art Review.

Iron deficiency and heart failure frequently co-occur, sparking clinical research into the role of iron repletion in this condition over the last 20 years. Although early nonrandomized studies and subsequent moderate-sized randomized controlled trials showed an improvement in symptoms and functional metrics with the use of intravenous iron, 3 recent larger trials powered to detect a difference in hard cardiovascular outcomes failed to meet their primary endpoints. Additionally, there are potential concerns related to side effects from intravenous iron, both in the short and long term. This review discusses the basics of iron biology and regulation, the diagnostic criteria for iron deficiency and the clinical evidence for intravenous iron in heart failure, safety concerns, and alternative therapies. We also make practical suggestions for the management of patients with iron deficiency and heart failure and outline key areas in need of future research.
