Comparison of Metoprolol and Tramadol with Remifentanil in Endoscopic Sinus Surgery: A Randomised Controlled Trial.

ABSTRACT: Objective:Controlled hypotension is commonly induced during functional endoscopic sinus surgery to limit mucosal bleeding. This may be detrimental to elderly patients and patients with arterial stenosis. The aim of this pilot study was to determine if a normotensive anaesthetic technique with sufficient analgesia and without profound vasodilation may reduce intraoperative bleeding and incidence of adverse haemodynamic effects associated with vasodilation and variable rate continuous infusions. Methods:In this double-blind randomised controlled trial in a tertiary care centre, a total of 88 patients were randomised to receive intravenously either 0.1 mg kg-1 metoprolol and 1 mg kg-1 tramadol following anaesthesia induction (MT group) or a bolus dose of 0.5 ?g kg-1 remifentanil following anaesthesia induction, followed by 0.25-0.5 ?g kg-1 min-1 remifentanil infusion (R group). The primary outcome was quality of surgical field and incidence of adverse haemodynamic effects. The secondary outcomes were time to achieve intraoperative bleeding score <3, bleeding rate and changes in cerebral regional oximetry. Results:A total of 105 patients were recruited, in which 88 were randomised. The median intraoperative bleeding score was similar (1, interquartile range: 1-1, p=0.69). The mean bleeding rate was lower in the MT group, although the difference was not significant (p=0.052, 95% CI 0 to 8.8). Hypotension, bradycardia and cerebral desaturation in the MT group were not observed compared to hypotension in 3 (7%), bradycardia in 18 (41%) and cerebral desaturation in 2 (5%) patients in the R group (p=0.241, p<0.001, p=0.474, respectively). Conclusion:Providing sufficient analgesia and eliminating stress response can provide stable heart rate and good surgical field with no need for additional hypotension. This normotensive technique may be useful in patients with stenotic arteries or ischaemic organ diseases.

Project description:BackgroundChronic rhinosinusitis (CRS) is a common source of ill health; 11% of UK adults reported CRS symptoms in a worldwide population study. Guidelines are conflicting regarding whether antibiotics should be included in primary medical management, reflecting the lack of evidence in systematic reviews. Insufficient evidence to inform the role of surgery contributes to a fivefold variation in UK intervention rates. The objective of this trial is to establish the comparative effectiveness of endoscopic sinus surgery (ESS) or a prolonged course of antibiotics (clarithromycin) in adult patients with CRS in terms of symptomatic improvement and costs to the National Health Service compared with standard medical care (intranasal medication) at 6 months.Methods/designA three-arm parallel-group trial will be conducted with patients who remain symptomatic after receiving appropriate medical therapy (either in primary or secondary care). They will be randomised to receive: (1) intranasal medication plus ESS, (2) intranasal medication plus clarithromycin (250 mg) or (3) intranasal medication plus a placebo. Intranasal medication (current standard medical care) is defined as a spray or drops of intranasal corticosteroids and saline irrigations. The primary outcome measure is the SNOT-22 questionnaire, which assesses disease-specific health-related quality of life. The study sample size is 600. Principal analyses will be according to the randomised groups irrespective of compliance. The trial will be conducted in at least 16 secondary or tertiary care centres with an internal pilot at six sites for 6 months.DiscussionThe potential cardiovascular side effects of macrolide antibiotics have been recently highlighted. The effectiveness of antibiotics will be established through this trial, which may help to reduce unnecessary usage and potential morbidity. If ESS is shown to be clinically effective and cost-effective, the trial may encourage earlier intervention. In contrast, if it is shown to be ineffective, then there should be a significant reduction in surgery rates. The trial results will feed into the other components of the MACRO research programme to establish best practice for the management of adults with CRS and design the ideal patient pathway across primary and secondary care.Trial registrationISRCTN36962030 .

Project description:BackgroundThe clinical relevance of the suggested hyperalgesic effects of remifentanil is still unclear, especially in the long term.ObjectiveThe current study evaluated the impact of remifentanil on thermal thresholds 3 days and 12 months after surgery, measured with Quantitative Sensory Testing.DesignA single-blind, randomised controlled trial.SettingA tertiary care teaching hospital in The Netherlands, from 2014 to 2016.PatientsA total of 126 patients aged between 18 and 85 years, undergoing cardiothoracic surgery via sternotomy (coronary artery bypass grafts and/or valve replacement) were included. Exclusion criteria were BMI above 35 kg m, history of cardiac surgery, chronic pain conditions, neurological conditions, allergy to opioids or paracetamol, language barrier and pregnancy.InterventionsPatients were allocated randomly to receive intra-operatively either a continuous remifentanil infusion or intermittent intra-operative fentanyl as needed in addition to standardised anaesthesia with propofol and intermittent intravenous fentanyl at predetermined time points.Main outcome measuresWarm and cold detection and pain thresholds 3 days and 12 months after surgery. In addition the use of remifentanil, presence of postoperative chronic pain, age, opioid consumption and pre-operative quality of life were tested as a predictor for altered pain sensitivity 12 months after surgery.ResultsBoth warm and cold detection, and pain thresholds, were not significantly different between the remifentanil and fentanyl groups 3 days and 12 months after surgery (P > 0.05). No significant predictors for altered pain sensitivity were identified.ConclusionEarlier reports of increased pain sensitivity 1 year after the use of remifentanil could not be confirmed in this randomised study using Quantitative Sensory Testing. This indicates that remifentanil plays a minor role in the development of chronic thoracic pain. Still, the relatively high incidence of chronic thoracic pain and its accompanying impact on quality of life remain challenging problems.Trial registrationThe study was registered at EudraCT (ref: 2013-000201-23) and ClinicalTrials.gov (https://clinicaltrials.gov/ct2/show/NCT02031016).
