Abstract
OBJECTIVES Haemodynamic changes following intravenous acetaminophen are well studied in adults. Limited data are published in critically ill paediatric patients, especially from the Middle East. We aim to investigate haemodynamic effects and incidence of hypotension with intravenous acetaminophen in critically ill children, with a focus on understanding factors influencing these effects. METHODS We retrospectively reviewed patients who received intravenous acetaminophen between July and December 2022. A haemodynamic event was defined as drop of >15% in systolic blood pressure (SBP) or mean arterial blood pressure (MAP) within 120 min after drug administration. Hypotension was defined as either drop in SBP below the 5th percentile for age, or a haemodynamic event associated with tachycardia, increased lactate or treatment with fluid/vasopressors. Logistic regression was performed to quantify relationships between patients' characteristics and the occurrence of haemodynamic event and hypotension. RESULTS A haemodynamic event was observed in 50/156 patients (32%) post-acetaminophen. Mean MAP (SD) before and after acetaminophen was 69.6 mm Hg (14.8) and 67.4 mm Hg (13.9), respectively (p=0.001). Mean SBP (SD) before and after acetaminophen was 95.4 mm Hg (18.2) and 92.8 mm Hg (19.2), respectively (p=0.006). Baseline MAP, median (interquartile range (IQR)) was 76.0 (64.0-85.3) and 66.0 (57.0-74.5) in patients with and without haemodynamic events, respectively (p=0.004). Only 38/156 patients (24%) met the definition for hypotension. Baseline MAP, median (IQR) was 62.0 (51.8-79.0) in patients with, and 68.5 (62.0, 79.3) in patients without hypotension (p=0.036). Baseline shock, vasoactives, mechanical ventilation and paediatric sequential organ failure assessment were not significantly associated with hypotension. Only MAP was found to be associated with both haemodynamic event (adjusted odds ratio (AOR) 1.05, 95% CI 1.02-1.10) and hypotension (AOR 1.06, 95% CI 1.02-1.10) even after controlling for other confounders. CONCLUSIONS Administration of intravenous acetaminophen in critically ill children can lead to haemodynamic changes, including clinically significant hypotensive events.

Abstract
Background and objective The negligible side effects of paracetamol along with its ease of availability have catapulted paracetamol to be a widely used medication in emergency room management to reduce pain and subsequent elevations in blood pressure (BP). Our study aimed to address the challenges in informed clinical decision-making in the emergency room following paracetamol intravenous infusion. Methods This was a retrospective cross-sectional study involving the extraction of data from electronic medical records of patients who received intravenous paracetamol infusion between January 2022 and May 2022. Demographic information and BP-related data were collected for analysis. Results We initially considered a total of 162 patient records, with 132 of them eventually meeting the inclusion criteria. Among patients receiving paracetamol infusion for 15 minutes or less, 34% showed a drop of 1-5 mmHg in systolic BP (SBP), while 26% experienced a drop of 6-10 mmHg. However, infusion time longer than 16 minutes did not significantly reduce SBP. Diastolic BP (DBP) was not significantly affected by the duration of the paracetamol infusion. Analysis of the drop in SBP revealed no significant associations with age, gender, or ethnicity. Mean arterial pressure (MAP) was not significantly affected by the duration of paracetamol infusion. Conclusion Our findings suggest that intravenous paracetamol infusion does not significantly lower BP in adults in the emergency room, except for infusions of shorter durations. However, various factors, including infusion rate, patient characteristics, and concomitant medications, may influence BP measurements. The study emphasizes the need for establishing standardized criteria and conducting further research to assess intravenous paracetamol's hemodynamic effects accurately.

Abstract
Purpose of Review To review the blood pressure (BP) effects of pain and analgesic medications and to help interpret BP changes in people suffering from acute or chronic pain. Recent Findings Acute pain evokes a stress response which prompts a transient BP increase. Chronic pain is associated with impaired regulation of cardiovascular and analgesia systems, which may predispose to persistent BP elevation. Also analgesics may have BP effects, which vary according to the drug class considered. Data on paracetamol are controversial, while multiple studies indicate that non-steroidal anti-inflammatory drugs may increase BP, with celecoxib showing a lesser impact. Hypotension has been reported with opioid drugs. Among adjuvants, tricyclic antidepressants and serotonin-norepinephrine reuptake inhibitors could be pro-hypertensive due to potentiation of adrenergic transmission. Summary Pain and analgesics may induce a clinically significant BP destabilization. The implications on hypertension incidence and BP control remain unclear and should be explored in future studies.

Abstract
Background Acetaminophen-induced hypotension has been reported in critically ill patients; however, it remains unclear whether mannitol, present as a stabilizing compound in acetaminophen formulations, affects hemodynamic changes. The objectives of this study were to clarify the direct effect of acetaminophen on blood pressure by comparing blood pressure changes after acetaminophen and intravenous immunoglobulin (IVIG) administration, both containing mannitol, in patients with sepsis and understand the risk factors for reduced blood pressure following acetaminophen administration. Methods This was a retrospective cohort study. Adult patients who were diagnosed with sepsis at Nippon Medical School Hospital, and who were undergoing continuous arterial blood pressure measurement and received intravenous acetaminophen or IVIG, were included. Results Overall, 185 patients were included, with 92 patients in the IVIG group and 93 in the acetaminophen group. The incidence of hypotension was 36.9% in the IVIG group (34 of 92 patients) and 58.0% in the acetaminophen group (54 of 93 patients) (OR = 8.26, p = 0.004). In a propensity score-matched cohort, 80 matched patients were selected. The incidence of hypotension was 37.5% in the IVIG group (15 of 40 patients) and 67.5% in the acetaminophen group (27 of 40 patients) (OR = 7.21, p = 0.007). Conclusions Acetaminophen induced substantially greater hypotension than IVIG in patients with sepsis, with both containing mannitol. Further studies are needed to clarify the effects on hemodynamics of mannitol contained in acetaminophen formulations.

Abstract
Objective We performed a single-center double-blinded, randomized trial to investigate the hemodynamic effects of IV paracetamol in patients with chronic liver disease (CLD) undergoing liver transplantation surgery. Patients with CLD are particularly susceptible to hemodynamic derangements given their low systemic vascular resistance state. Accordingly, hypotension is common in this setting. The hemodynamic effects of IV paracetamol in patients undergoing elective liver transplantation are unknown, therefore we evaluated whether the intraoperative administration of IV paracetamol in patients with chronic liver disease undergoing liver transplantation results in adverse hemodynamic effects. The primary end point was a change in systolic blood pressure 30-min after the preoperative infusion. Results Twenty-four participants undergoing liver transplantation surgery were randomly assigned to receive a single bolus of IV paracetamol (1 g paracetamol + 3.91 g mannitol per 100 mL) (n = 12) or placebo (0.9% Saline 100 mL) (n = 12). All participants completed their study intervention, and there were no breaches or violations of the trial protocol. Baseline characteristics were similar in both groups. There were no significant differences regarding surgical duration, intraoperative use of fluids, and intraoperative noradrenaline use. After the administration of paracetamol there were no significant differences observed in blood pressure or other hemodynamic parameters when compared to placebo.

Abstract
Aim To understand the prevalence and epidemiology of paracetamol‐induced hypotension and clinical implications for contemporaneous practice. Design Narrative review. Methods In May and June 2020, an open‐date literature search of English publications indexed in ProQuest, PubMed, and EBSCO was conducted with the search terms ‘acetaminophen’ and ‘hypotension’ and related search combinations (‘paracetamol’, ‘propacetamol’, ‘low blood pressure’, ‘fever’, ‘sepsis’, and ‘shock’) to identify peer‐reviewed publications of blood pressure changes after paracetamol administration in humans. Results A pattern of blood pressure reduction following the administration of paracetamol is demonstrated in the 27 studies included in this review. Haemodynamic intervention often followed persistent blood pressure reduction, and was greatest in febrile critically ill patients who received parenteral paracetamol.

Abstract
BACKGROUND Acetaminophen is commonly used as part of multimodal analgesia for acute pain. The intravenous formulation offers a more predictable bioavailability compared to oral and rectal acetaminophen. There have been reports of hypotension with intravenous acetaminophen attributable to centrally mediated and vasodilatory effects. We tested the hypothesis that in adults having abdominal surgery the use of intravenous acetaminophen versus placebo for postoperative pain management is associated with a decrease in mean arterial pressure (MAP) after its administration. METHODS This is a substudy of eFfect of intravenous ACetaminophen on posToperative hypOxemia after abdominal surgeRy (FACTOR) trial (NCT02156154). FACTOR trial randomly assigned adults undergoing abdominal surgery to either 1 g of acetaminophen or placebo every 6 hours during the first postoperative 48 hours. Continuous monitoring of blood pressure was obtained by noninvasive ViSi Mobile device (Sotera Wireless, Inc, San Diego, CA) at 15-second intervals during initial 48 hours postoperatively. We excluded patients without continuous monitoring data available. The primary outcome was the MAP difference between MAP 5 minutes before study drug administration (baseline) and MAP 30 minutes poststudy drug administration initiation. We used a linear mixed effects model to assess the treatment effect on MAP change. The secondary outcome was MAP area under baseline (AUB) during the 30 minutes after treatment. In a sensitivity analysis of change in MAP from predrug to postdrug administration, we instead used postdrug MAP as the outcome adjusting for the baseline MAP in the model. RESULTS Among 358 patients analyzed, 182 received acetaminophen and 176 placebo. The mean (standard deviation [SD]) of average MAP change was -0.75 (5.9) mm Hg for the treatment and 0.32 (6.3) mm Hg for the placebo. Acetaminophen was found to decrease the MAP from baseline more than placebo after drug administration. The estimated difference in mean change of MAP was -1.03 (95% confidence interval [CI] -1.60 to -0.47) mm Hg; P < .001. The sensitivity analysis showed postoperative MAP in the acetaminophen group was 1.33 (95% CI, 0.76-1.90) mm Hg lower than in the placebo group (P < .001). The median of MAP AUB was 33 [Q1 = 3.3, Q3 = 109] mm Hg × minutes for the treatment and 23 [1.6, 79] mm Hg × minutes for the placebo. Acetaminophen was found to increase the AUB with an estimated median difference of 15 (95% CI, 5-25) mm Hg × minutes (P = .003). CONCLUSIONS Intravenous acetaminophen decreases MAP after its administration. However, this decrease does not appear to be clinically meaningful. Clinicians should not refrain to use intravenous acetaminophen for acute pain management because of worries of hypotension.

Acetaminophen increases pulmonary and systemic vasomotor tone in the newborn rat. Pediatr Res 2020; 87:1171-1176.

Abstract
BACKGROUND Acetaminophen is widely prescribed to both neonates and young children for a variety of reasons. In adults, therapeutic usage of acetaminophen induces systemic arterial pressure changes and exposure to high doses promotes tissue toxicity. The pulmonary vascular effects of acetaminophen at any age are unknown. Hypothesizing that, early in life, it promotes vasomotor tone changes via oxidative stress, we tested the in vitro acetaminophen effects on intrapulmonary and carotid arteries from newborn and adult rats. METHOD We measured the acetaminophen dose-response in isometrically mounted arteries and pharmacologically evaluated the factors accounting for its vasomotor effects. RESULTS Acetaminophen induced concentration- and age-dependent vasomotor tone changes. Whereas a progressive increase in vasomotor tone was observed in the newborn, the adult arteries showed mostly vasorelaxation. Inhibition of endogenous nitric oxide generation with L-NAME and the use of the peroxynitrite decomposition catalyst FeTPPS (Fe(III)5,10,15,20-tetrakis(4-sulfonatophenyl)porphyrinato chloride) mostly abolished the drug-induced increase in newborn pulmonary vasomotor tone CONCLUSIONS: In newborn rats, acetaminophen increases pulmonary vasomotor tone via peroxynitrite generation. Given its therapeutic usage, further clinical studies are warranted to assess the acetaminophen effects on the newborn pulmonary and systemic vascular resistance.

Abstract
OBJECTIVE Intravenous acetaminophen/paracetamol (APAP) is well documented to cause hypotension. Since the patients receiving intravenous APAP are usually critically ill, any severe hemodynamic changes, as with those associated with APAP, can be life-threatening. The mechanism underlying this dangerous iatrogenic effect of APAP was unknown. Approach and Results: Here, we show that intravenous APAP caused transient hypotension in rats, which was attenuated by the Kv7 channel blocker, linopirdine. APAP metabolite N-acetyl-p-benzoquinone imine caused vasodilatation of rat mesenteric arteries ex vivo. This vasodilatation was sensitive to linopirdine and also the calcitonin gene-related peptide antagonist, BIBN 4096. Further investigation revealed N-acetyl-p-benzoquinone imine stimulates calcitonin gene-related peptide release from perivascular nerves, causing a cAMP-dependent activation of Kv7 channels. We also show that N-acetyl-p-benzoquinone imine enhances Kv7.4 and Kv7.5 channels overexpressed in oocytes, suggesting that it can activate Kv7.4 and Kv7.5 channels directly, to elicit vasodilatation. CONCLUSIONS Direct and indirect activation of Kv7 channels by the APAP metabolite N-acetyl-p-benzoquinone imine decreases arterial tone, which can lead to a drop in blood pressure. Our findings provide a molecular mechanism and potential preventive intervention for the clinical phenomenon of intravenous APAP-dependent transient hypotension.

Abstract
BACKGROUND The impact of the left atrial low-voltage area (LVA) on the cardiac function improvement following ablation for atrial fibrillation (AF) is unclear. METHODS In 49 patients with paroxysmal AF who underwent ablation, the left ventricular stroke volume index (SVI) was repeatedly measured using an impedance cardiography until 6 months after ablation. We defined the cardiac function improvement as a 20% increase in the SVI. The LVA (the area with the voltage amplitude of <0.5 mV) was assessed before ablation. RESULTS The reduced baseline SVI (<33 mL/m2) was observed in 18 (37%) patients. The SVI increased following ablation (from 36 ± 5 to 39 ± 6 mL/m2, P < .001). We observed the cardiac function improvement in 14 (29%) patients. The LVA was smaller in patients with the improved cardiac function than in those without (8.3% ± 5.2% vs 14.0% ± 8.5%, P = .026). The multivariate analysis revealed that only the LVA was independently associated with the cardiac function improvement (odds ratio, 0.878; 95% confidence interval: 0.778-0.991, P = .036). Furthermore, LVAs of the anterior (7.9% ± 7.6% vs 18.2% ± 15.5%, P = .022), septal (12.0 ± 7.3% vs 20.7% ± 13.8%, P = .031), and roof walls (6.9% ± 6.0% vs 16.9% ± 15.2%, P = .022) were smaller in patients with the improved cardiac function than in those without. CONCLUSIONS The LVA was related to the cardiac function improvement following ablation in patients with paroxysmal AF.

Abstract
OBJECTIVES Acetaminophen is ubiquitously used as antipyretic/analgesic administered IV to patients undergoing surgery and to critically ill patients when enteral routes are not possible. Widely believed to be safe and free of adverse side effects, concerns have developed in adult literature regarding the association of IV acetaminophen and transient hypotension. We hypothesize that there are hemodynamic effects after IV acetaminophen in the PICU and assess the prevalence of such in a large pediatric cardiovascular ICU population using high-fidelity data. DESIGN Observational study analyzing an enormous set of continuous physiologic data including millions of beat to beat blood pressures surrounding medication administration. SETTING Quaternary pediatric cardiovascular ICU between January 1, 2013, and November 13, 2017. PATIENTS All patients less than or equal to 18 years old who received IV acetaminophen. Mechanical support devices excluded. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Physiologic vital sign data were analyzed in 5-minute intervals starting 60 minutes before through 180 minutes after completion. Hypotension defined as mean arterial pressure -15% from baseline and relative hypotension defined -10%. Only doses where patients received no other medications, including vasopressors, within the previous hour were included. t test and a correlation matrix were used to eliminate correlated factors before a logistic regression analysis was performed. Six-hundred eight patients received 777 IV acetaminophen doses. Median age was 8.8 months (interquartile range, 2-62 mo) with a dose of 12.5 mg/kg (interquartile range, 10-15 mg/kg). Data were normalized for age and reference values. One in 20 doses (5%) were associated with hypotension, and one in five (20%) associated with relative hypotension. Univariate analysis revealed hypotension associated with age, baseline mean arterial pressure, and skin temperature (p = 0.05, 0.01, and 0.09). Logistic regression revealed mean arterial pressure (p = 0.01) and age (p = 0.05) remained predictive for hypotension. CONCLUSIONS In isolation of other medication, a hemodynamic response to IV acetaminophen has a higher prevalence in critically ill children with cardiac disease than previously thought and justifies controlled studies in the perioperative and critical care setting. The added impact on individual patient hemodynamics and physiologic instability will require further study.

Abstract
AIM Studies in adults have reported frequent episodes of blood pressure drops following intravenous paracetamol administration. We aimed to investigate the hemodynamic effects of intravenous paracetamol in critically ill children. METHODS The charts of 100 pediatric intensive care patients (age range 0.1-18 years) who were treated with intravenous paracetamol between March and September 2017 were retrospectively reviewed. A hemodynamic event was defined as a drop of > 15% in systolic or mean arterial blood pressure within 120 min after drug administration. Hypotension was defined as either a drop in systolic blood pressure (SBP) below the 5th percentile for age or a hemodynamic event associated with tachycardia, increased lactate level, or treatment with a fluid bolus or vasopressors. RESULTS A hemodynamic event was observed in 39 patients (39%). In these patients, SBP was in the pre-hypertension or hypertension values in 36/39 patients before paracetamol administration, median (IQR) SBP decreased from the 99th (95-99) percentile for age before to the 50th (50-95) percentile after paracetamol (p < 0.001) and mean heart rate was 137 bpm before treatment and 115 bpm after (p = 0.002). SBP values did not drop below the 5th percentile in any patient. In 15 patients diagnosed with shock on admission, paracetamol treatment did not cause an increase in vasopressor treatment after drug administration. CONCLUSIONS In the present study of critically ill pediatric patients, intravenous paracetamol administration was associated with a drop in SBP from high to normal values for age, possibly due to pain relief, with no evidence for a negative hemodynamic event.

Abstract
Excessive or inappropriate use of non-steroidal anti-inflammatory drugs can affect cardiovascular and renal function. Non-steroidal anti-inflammatory drugs, both non-selective and selective cyclooxygenase 2 inhibitors, are among the most widely used drugs, especially in the elderly, with multiple comorbidities. Exposition to a polypharmacy burden represents a favourable substrate for the onset of non-steroidal anti-inflammatory drug-induced deleterious effects. Cardiovascular and renal issues concerning the occurrence of myocardial infarction, atrial fibrillation, heart failure and arterial hypertension, as well as acute or chronic kidney damage, become critical for clinicians in their daily practice. We discuss current available knowledge regarding prostanoid physiology in vascular, cardiac and renal systems, pointing out potential negative non-steroidal anti-inflammatory drug-related issues in clinical practice.

Abstract
Objective: Recent literature suggests that intravenous (IV) administration may cause hypotension in hospitalized patients; data further suggest that this effect is most pronounced in the critically ill. The purpose of this review is to identify and evaluate current literature that addresses the incidence and implications of IV acetaminophen-induced hypotension. Data Sources: A literature search of MEDLINE, Cochrane, and EMBASE databases was performed (2002-2019) using the following terms: acetaminophen, paracetamol, intravenous, and hypotension. Abstracts and peer-reviewed publications were reviewed. Study Selection and Data Extraction: Relevant English-language studies conducted in humans evaluating the hemodynamic effects of IV acetaminophen were considered. Data Synthesis: A majority of the 19 studies included in this review identified a statistically significant drop in hemodynamic variables after the administration of 500 to 1000 mg IV acetaminophen as measured by changes in systolic blood pressure, diastolic blood pressure, or mean arterial pressure. Of the trials reporting vasopressor use, the authors found a significant increase in vasopressor requirements following IV acetaminophen administration. Relevance to Patient Care and Clinical Practice: This review represents the first comprehensive review of IV acetaminophen-induced hypotension. The findings raise the question of whether IV acetaminophen is an appropriate choice for inpatient pain or temperature management in the critically ill. Conclusions: Available evidence indicates that the administration of IV acetaminophen may be harmful in the critically ill. Additional monitoring is likely required when using IV acetaminophen in this specific population, particularly if a patient is hemodynamically unstable prior to administration.

Abstract
BACKGROUND The effects of catheter ablation for atrial fibrillation (AF) on hemodynamic parameters in patients with preserved left ventricular (LV) systolic function are unclear. Methods and Results: We enrolled 178 patients with AF (paroxysmal, 108; persistent, 70) with preserved LV systolic function who underwent AF ablation. The stroke volume index (SVI) was repeatedly measured using impedance cardiography. Reduced SVI (SVI, <33 mL/m2) was observed in 55% of patients before ablation. In patients with paroxysmal AF, the SVI did not change immediately after ablation (from 35±6 mL/m2to 35±5 mL/m2; P=0.652); however, it increased 1 month after ablation and further increased 6 months after ablation (1 month, 37±6 mL/m2, P<0.001; 6 months, 38±6 mL/m2, P<0.001). In patients with persistent AF, the SVI increased immediately after ablation (from 30±5 mL/m2to 36±6 mL/m2; P<0.001) and further increased until 6 months after ablation (1 month, 37±6 mL, P<0.001; 6 months, 38±5 mL/m2, P<0.001). The baseline SVI was the strongest predictor of the cardiac function improvement with an area under the curve of 0.828. CONCLUSIONS The restoration and maintenance of sinus rhythm using catheter ablation increased the SVI in patients with preserved LV systolic function.

Abstract
The hemodynamic effects of intravenous (IV) paracetamol in patients undergoing cardiac surgery are unknown. We performed a prospective single center placebo controlled randomized study with parallel group design in adult patients undergoing elective cardiac surgery. Participants received paracetamol (1 gram) IV or placebo (an equal volume of 0.9% saline) preoperatively followed by two postoperative doses 6 hours apart. The primary endpoint was the absolute change in systolic (SBP) 30 minutes after the preoperative infusion, analysed using an ANCOVA model. Secondary endpoints included absolute changes in mean arterial pressure (MAP) and diastolic blood pressure (DPB), and other key hemodynamic variables after each infusion. All other endpoints were analysed using random-effect generalized least squares regression modelling with individual patients treated as random effects. Fifty participants were randomly assigned to receive paracetamol (n = 25) or placebo (n = 25). Post preoperative infusion, paracetamol decreased SBP by a mean (SD) of 13 (18) mmHg, p = 0.02, compared to a mean (SD) of 1 (11) mmHg with saline. Paracetamol decreased MAP and DBP by a mean (SD) of 9 (12) mmHg and 8 (9) mmHg (p = 0.01 and 0.02), respectively, compared to a mean (SD) of 1 (8) mmHg and 0 (6) mmHg with placebo. Postoperatively, there were no significant differences in pressure or flow based hemodynamic parameters in both groups. This study provides high quality evidence that the administration of IV paracetamol in patients undergoing cardiac surgery causes a transient decrease in preoperative blood pressure when administered before surgery but no adverse hemodynamic effects when administered in the postoperative setting.

Abstract
BACKGROUND Antipyretics are among the most widely prescribed drugs in German hospitals. Despite this widespread use, their role for treatment of critically ill patients still remains unclear. In particular, the questionable positive effects of reducing fever are discussed. OBJECTIVES In this review we aimed to summarize and discuss current study results covering the use of antipyretics in critically ill patients. Suspected effects with regard to fever reduction and lethality should be considered. MATERIALS AND METHODS A selective literature search was carried out in the PubMed database. We reviewed the bibliographies of all work considered relevant. RESULTS There are only a few studies on the use of antipyretics in intensive care patients, which are difficult to compare systematically due to different designs, protocols and endpoints. All in all, the decrease in temperature was very low (0.3 °C) and showed even adverse effects on 28-days mortality in sepsis. In patients with sepsis and ASS medication, a decreased mortality has been shown in retrospective analysis. CONCLUSIONS The benefit of fever control using antipyretics in intensive care patients with regard to endpoints like lethality remains unclear. Randomized controlled trials with suitable protocols and endpoints are needed to provide a solid base for development of guidelines.

Abstract
PURPOSE Paracetamol has been associated with a reduction in blood pressure, especially in febrile, critically-ill adults. We hypothesised that blood pressure would fall following administration of paracetamol in critically-ill children and this effect would be greater during fever and among children with a high body surface area to weight ratio. METHODS A 12-month prospective observational study of children (0-16years) admitted to paediatric intensive care, who underwent pulse contour analysis and received paracetamol concurrently. RESULTS Mean arterial blood pressure decreased significantly by 4.7% from baseline (95% CI 1.75-8.07%) in 31 children following 148 doses of paracetamol. The nadir was 2-hour post-dose. The effect was pronounced in children with fever at baseline (6.4%, 95% CI 2.8-10%), although this was not statistically significant. There was no simple relationship between this effect and body surface area to weight ratio. The association between a change in blood pressure and changes in heart rate or measured stroke volume was poor; therefore it was likely that a change in the systemic vascular resistance contributes most to this effect. CONCLUSION There is a significant but modest reduction in blood pressure post-paracetamol in critically-ill children. This is likely related to a change in systemic vascular resistance.

Abstract
OBJECTIVE To study the biologic effect of paracetamol, an inhibitor of prostaglandin synthase, on early closure of ductus arteriosus, and to evaluate possible adverse effects associated with the drug. STUDY DESIGN In a controlled, double-blind, phase I-II trial, very low gestational age (<32 weeks) infants requiring intensive care were randomly assigned to intravenous paracetamol or placebo (0.45% NaCl). A loading dose of 20 mg/kg was given within 24 hours of birth, followed by 7.5 mg/kg every 6 hours for 4 days. Daily cardiac ultrasound examinations of ductal calibers were performed before the first dose, and until 1 day after the last dose. The main outcome was a decrease in the ductal caliber without side effects. RESULTS Of 63 screened infants, 48 were randomized: 23 were assigned to paracetamol and 25 to placebo. Before the intervention, their ductal calibers were similar. During the intervention, the ductus closed faster in the paracetamol group (hazard ratio 0.49, 95% CI 0.25-0.97, P = .016). The mean (95% CI) postnatal ages for ductal closure were 177 hours (31.1-324) for the paracetamol-treated vs 338 hours (118-557) for controls (P = .045). Paracetamol serum levels were within the therapeutic range, and no adverse effects were evident. CONCLUSIONS Prophylactic paracetamol induced early closure of the ductus arteriosus without detectable side effects. Further trials are required to determine whether intravenous paracetamol may safely prevent symptomatic patent ductus arteriosus.

Abstract
OBJECTIVES To propose approaches tailored to the specific needs of neonates, such as structured product development programmes, with the ultimate goal to improve the safe and effective use of analgosedatives in these fragile patients. KEY FINDINGS The feasibility and relevance of a structured product development programme in neonates (optimal study design based on preliminary data; model development; internal, external and prospective evaluation; an individualized dosing regimen; long-term safety; pharmacogenetics) are illustrated for the use of morphine. Based on changes in clinical practices, similar development plans are in progress for short-acting analgosedatives such as propofol, but are in need of tailored pharmacodynamic tools to assess and quantify effects. Furthermore, for drugs like paracetamol where there is already sufficient clinical pharmacology knowledge, attention needs to be given to long-term safety aspects. Finally, new covariates such as pharmacogenetics might further improve neonatal pain management, but clearly need to be integrated with other well-established covariates like age or weight. SUMMARY Product development programmes for analgosedatives in neonates are needed. These programmes should be tailored to their specific needs (short-acting sedation, pain relief), should include long-term safety and should incorporate the exploration of newer covariates like pharmacogenetics.

Abstract
AIM The haemodynamic effects of intravenous paracetamol have not been systematically investigated. We compared the physiological effects of intravenous mannitol-containing paracetamol, and an equivalent dosage of mannitol, and normal saline 0.9% in healthy volunteers. METHODS We performed a blinded, triple crossover, randomized trial of 24 adult healthy volunteers. Participants received i.v. paracetamol (1 g paracetamol +3.91 g mannitol 100 ml(-1) ), i.v. mannitol (3.91 g mannitol 100 ml(-1) ) and i.v. normal saline (100 ml). Composite primary end points were changes in mean arterial pressure (MAP), systolic blood pressure (SBP) and diastolic blood pressure (DBP) measured pre-infusion, during a 15 min infusion period and over a 45 min observation period. Systemic vascular resistance index (SVRI) and cardiac index were measured at the same time points. RESULTS Infusion of paracetamol induced a transient yet significant decrease in blood pressures from pre-infusion values (MAP -1.85 mmHg, 95% CI -2.6, -1.1, SBP -0.54 mmHg, 95% CI -1.7, 0.6 and DBP -1.92 mmHg, 95% CI -2.6, -1.2, P < 0.0001), associated with a transient reduction in SVRI and an increase in cardiac index. Changes were observed, but to a lesser extent with normal saline (MAP -0.15 mmHg, SBP +1.44 mmHg, DBP --0.73 mmHg, P < 0.0001), but not with mannitol (MAP +1.47 mmHg, SBP +4.03 mmHg, DBP +0.48 mmHg, P < 0.0001). CONCLUSIONS I.v. paracetamol caused a transient decrease in blood pressure immediately after infusion. These effects were not seen with mannitol or normal saline. The physiological mechanism was consistent with vasodilatation. This study provides plausible physiological data in a healthy volunteer setting, supporting transient changes in haemodynamic variables with i.v. paracetamol and justifies controlled studies in the peri-operative and critical care setting.
