Acetaminophen and paracetamol

Postby Nemi В» 05.08.2019

In this highly original study, Sophie Esch approaches political violence through its most direct but also most symbolic tool: the firearm.

In this trial, some women were fertile but not using contraceptives and therefore did not meet the inclusion criteria. Paracetamol was given at mg to patients in the paractamol plus ibuprofen group and in the paracetamol plus placebo group, and patients received mg in the half-strength group.

Ibuprofen was given at mg to patients in the paracetamol plus ibuprofen group and in the ibuprofen plus placebo group, and patients received mg in the half-strength group. Blue dotted lines indicate median level of consumption.

Final date of follow-up was January 1, Median hour morphine consumption was 20 mg The relative risk of SAE was 1. However, the combination did not result in a clinically important improvement over ibuprofen alone, suggesting that ibuprofen alone may be a reasonable option for early postoperative oral analgesia. Multimodal analgesia is the leading principle for management of acute postoperative pain.

Recent guidelines recommend combinations of at least paracetamol acetaminophen and a nonsteroidal anti-inflammatory drug NSAID for most types of surgeries. The analgesic effects of both paracetamol and an NSAID in postoperative pain are well established when the individual drugs are compared with placebo.

In the perioperative period, the safety of NSAIDs, including the combination with paracetamol, is largely unknown. NSAIDs have been linked to adverse events in other settings, 11 , 12 however, this link has not been investigated in the perioperative period. The hypotheses were as follows: 1 the combination of paracetamol and ibuprofen would lead to lower opioid consumption compared with each drug alone; 2 the combination of lower doses of paracetamol and ibuprofen would lead to opioid consumption comparable to or lower than higher doses of each drug alone; and 3 ibuprofen would increase the rate of SAEs.

This trial was a multicenter, randomized, blinded trial in patients having planned primary THA investigating the use of paracetamol, ibuprofen, and combinations of both drugs. The trial protocol 13 and the statistical analysis plan 15 appear in Supplement 1. All participants provided written informed consent prior to enrollment. The trial was conducted at 6 hospitals in Denmark 5 public and 1 private , ranging from smaller regional hospitals to large university hospitals.

All patients scheduled for elective, primary, unilateral THA were screened for participation. Key exclusion criteria were daily use of opioids however, patients using tramadol or codeine were not excluded and contraindications to ibuprofen or paracetamol. A complete list of inclusion and exclusion criteria is provided in Supplement 2.

All patients received one of the following interventions: paracetamol mg plus ibuprofen mg, paracetamol mg plus matching placebo, ibuprofen mg plus matching placebo, or half-strength paracetamol mg plus ibuprofen mg.

The trial medication was given orally starting 1 hour before surgery and given every 6 hours for 24 hours postoperatively for a total of 4 doses of the medication on the first postoperative day. Patients were randomized by a web-based central allocation service provided by the Copenhagen Trial Unit, Denmark, to 1 of 4 groups in a ratio, using a computer-generated randomized sequence with varying unknown block sizes either 4 or 8 and stratification for site.

The randomization code could only be broken by calling a hour telephone service provided by the Copenhagen Trial Unit. The trial medication paracetamol, ibuprofen, and placebo was packed and masked by the Pharmacy of the Capital Region, Herlev, Denmark. A dose of trial medication consisted of 3 identical opaque capsules. Patients, staff, investigators, outcome assessors, and the statistician were blinded to the intervention.

Based on the masked results, abstracts were written and agreed upon by the trial steering committee April 6, before revealing the identity of the groups Supplement 2. The patients had either cementless or cemented components inserted. Patients received spinal preferred or general anesthesia. For spinal anesthesia, bupivacaine plain mg was used, combined with continuous propofol infusion if sedation was needed.

For general anesthesia, propofol and remifentanil were preferred, and at the end of surgery, intravenous sufentanil 0.

According to the protocol, additional boluses of 2-mg morphine on patient request were allowed during the first postoperative hour. These additional dosages were added to the total PCA morphine consumption for the primary outcome. If any other opioid was administered during the first 24 hours postoperatively due to mistake, malfunction of PCA pump, or other such problem , this was converted to morphine equivalents and added to the PCA morphine.

No pain medication including peripheral regional anesthesia other than the trial medication and the PCA morphine was allowed. Patients usually treated with gabapentinoids, glucocorticoids, selective serotonin reuptake inhibitors, tramadol, or codeine continued these medications during the intervention period hours.

The trial had 2 co—primary outcomes: total morphine consumption for the first 24 hours postoperatively and proportion of patients with 1 or more modified SAEs from the surgery to 90 days postoperatively.

The outcome of proportion of modified SAEs was defined as SAE according to ICH-GCP guidelines 14 defined as any untoward medical occurrence that results in death; is life-threatening; requires hospitalization or prolongation of hospitalization; or results in significant or persistent disability or incapacity, birth defects, or a medical intervention to prevent 1 of the before-mentioned outcomes excluding prolongation of hospitalization because these could not be adjudicated because of differences in length of stay.

Data regarding postoperative hospitalization were collected from Danish National Patient Registry, and vital status was collected from the Danish Civil Registration System. All patients were interviewed by phone at 90 days postoperatively to investigate if there had been any events requiring medical intervention since surgery.

The exploratory outcomes were level of nausea, sedation, dizziness none, mild, moderate, and severe; patients indicated their own level ; vomiting number of vomiting episodes ; use of antiemetic ondansetron, milligrams ; blood loss during the surgical procedure milliliters ; and days alive and outside hospital within 90 days postrandomization. To maintain an overall familywise error rate of less than.

Furthermore, the threshold for type I error rate was adjusted for the pairwise comparisons between the 4 groups 6 comparisons to. Because there was no prior literature clearly identifying what a minimal clinically important difference MCID would be for the reduction of morphine use after surgery, we established the MCID based on our clinical experience.

For the co—primary outcome of the proportion of modified SAEs, a power of 0. Analyses were performed by an independent statistician J. The primary analyses were by the intention-to-treat principle and the primary analysis population was composed of randomized patients who underwent THA surgery. The primary analysis of the co—primary outcome of morphine consumption was pairwise comparisons between groups using the Van Elteren test, due to nonnormally distributed data.

Secondary analyses included adjusted analyses for sex, age, prior use of NSAIDs, and prior use of paracetamol and analyses based on the strictly per-protocol population. All analyses were stratified for site. For the primary and secondary outcomes, site and variables used in the adjusted analyses were tested for interaction with intervention groups by adding an interaction term in the generalized estimating equation model using the STATA 15 command XTGEE.

Data are presented as means with standard deviations for normally distributed data and medians with The level of significance and corresponding confidence interval were. From December to October , a total of participants were enrolled in this trial. Following randomization, surgery was canceled for 3 participants; thus, patients were included in the primary analysis population Figure 1.

The demographic, surgical, and anesthesia characteristics Table 1 were comparable between groups. Multiple imputation was not used for any outcome because there were few missing data. The final date of follow-up was January 1, In the pairwise comparisons Table 2 , the median difference was 16 mg The difference was 8 mg The differences between the paracetamol plus ibuprofen group and the half-strength paracetamol plus ibuprofen group 8 mg [ There was no significant difference between the ibuprofen-alone group and the half-strength paracetamol plus ibuprofen group 2 mg [ For the comparison between the paracetamol plus ibuprofen group and the half-strength paracetamol plus ibuprofen group, we found a qualitative and statistically significant interaction between intervention and site eTables 1 and 2 in Supplement 2.

The corresponding RR was 1. At 6 hours, the only statistically significant difference in pain scores Table 3 was between the parecetamol plus ibuprofen group and the paracetamol-alone group at rest 8 mm [ At 24 hours, the paracetamol plus ibuprofen group had lower pain scores than the paracetamol-alone group 11 mm [ At 24 hours, the paracetamol plus ibuprofen group had lower pain scores at rest than all other groups compared with the paracetamol-alone group 11 mm [ There were no significant differences in adverse events in any pairwise comparison Table 3 ; eTable 5 in Supplement 2.

Key exploratory findings were reduced risk of nausea at 24 hours for group paracetamol plus ibuprofen group compared with all other groups paracetamol-alone group [RR, 0. Key findings from the secondary analyses were that the differences in morphine consumption between the paracetamol plus ibuprofen group and the ibuprofen-alone group were not statistically significant in adjusted analyses and analyses in the per-protocol population, contrary to the main unadjusted analysis in the primary analysis population.

All exploratory outcomes and results from secondary analyses are found online eTables 6 to 13 in Supplement 2. This trial demonstrated that a combination of paracetamol mg and ibuprofen mg resulted in a clinically relevant reduction in morphine consumption compared with paracetamol mg alone on the first postoperative day after THA.

For all other comparisons, the differences in morphine consumption were less than the predefined minimal clinically relevant difference of 10 mg the difference in morphine consumption between the paracetamol [ mg] plus ibuprofen [ mg] group vs the ibuprofen [ mg]—alone group was 6 mg.

Further, the trial showed a substantial proportion of patients with 1 or more SAEs within 90 days after surgery; however, there was no statically significant difference in patients randomized to receuve ibuprofen compared with patients randomized to receive paracetamol only.

These findings from a multicenter trial with few exclusions due to logistic reasons support the principle of multimodal analgesia with paracetamol plus ibuprofen compared with paracetamol alone for the first postoperative day.

However, compared with ibuprofen alone, the morphine-sparing effect was below the prespecified threshold for clinically important postoperative morphine reduction. In light of the current opioid crisis, 26 using the lowest possible amount of opioid is important. A recent network meta-analysis investigating all nonopioid analgesics for major surgery 28 indicated similar results regarding morphine-sparing effects as this trial, but the network meta-analysis only included very few trials with direct comparisons of the combination of paracetamol and an NSAID vs paracetamol alone, and an NSAID alone.

The authors of the network meta-analysis found no association with opioid-associated adverse effects or SAEs, and both trials with low, high, and unclear risk of bias were included in their analyses. The results from this trial could not replicate this finding. To our knowledge, this is the first trial to include systematic day follow-up for safety through national registries and telephone interviews as a primary outcome in this research area, in which reporting of harm in perioperative pain trials is often inadequate.

This trial has several limitations. First, the intervention period was only 24 hours, and a prolonged intervention period could have been more appropriate as treatment with paracetamol plus ibuprofen seldom is used for only 24 hours in a clinical context. Second, there were fewer patients having spinal anesthesia in the half-strength paracetamol plus ibuprofen group, which might have influenced morphine consumption and pain levels.

Third, no specific analgesics were recommended to patients in the follow-up period, and only a few patients did not use NSAIDs at all eTable 3 in Supplement 2. This makes attribution of the SAEs to ibuprofen difficult; however, there were no significant differences in NSAID use in the follow-up period between groups, and the sensitivity analysis excluding patients using NSAIDs in the follow-up period from the paracetamol-only group did not alter the conclusion from the main analysis.

Fifth, the power of the null test for interaction between the collated groups receiving ibuprofen and SAEs was not assessed a priori, thus, it is not certain that it is reasonable to combine these groups.

Among patients undergoing total hip arthroplasty, paracetamol plus ibuprofen significantly reduced morphine consumption compared with paracetamol alone in the first 24 hours after surgery; there was no statistically significant increase in serious adverse events in the pooled groups receiving ibuprofen alone vs with paracetamol alone.
