Postoperative pain is a major problem, especially in orthopedic surgery. Our data suggest suboptimal pain management after total knee arthroplasty. This study evaluated a sufentanil sublingual tablet ...system (Zalviso) to optimize postoperative pain treatment. This retrospective, single-center, cohort study was conducted between January 2017 and September 2017. Zalviso as standard treatment was compared with a cohort receiving oxycodone (Oxy) immediate release and Oxy extended release and another receiving Oxy immediate release, Oxy extended release, and dexamethasone (Dexa + Oxy). The primary end point, pain intensity, was assessed on a numeric rating scale (NRS). Highest, lowest, and number of NRS scores >7 were collected. Secondary end points included length of hospital stay, nausea, and mobilization on the day of surgery. Patients receiving Dexa + Oxy had a lower lowest-pain intensity on day 0 (median 0, IQR 0-0) when compared to patients receiving Oxy (median 2, IQR 0-3;
<0.0001) or Zalviso (median 2, IQR 0-4;
<0.0001). No differences were observed on day 1 or 2. No differences were observed in highest pain score or number of patients reporting NRS scores > 7. Patients treated with Dexa + Oxy or Zalviso were discharged earlier compared to patients treated with Oxy (
<0.001). Patients treated with Zalviso experienced more nausea compared to other groups on day 0 and day 1 (
<0.001). Patients treated with Dexa + Oxy had a higher percentage of mobilization on the day of surgery compared to Oxy and Zalviso (
<0.001). In conclusion, Zalviso did not improve postoperative pain management in patients undergoing total knee arthroplasty and increased nausea.
IntroductionSurgical site infections (SSI) are a common postoperative complication. During the development of the new WHO guidelines on SSI prevention, also in the Netherlands was concluded that ...perioperative care could be optimised beyond the current standard practice. We selected a limited set of readily available, cheap and evidence-based interventions from these new guidelines that are not part of standard practice in the Netherlands and formulated an Enhanced PeriOperative Care and Health bundle (EPOCH). Here, we describe the protocol for an open-label, randomised controlled, parallel-group, superiority trial to test the effect of the EPOCH bundle added to (national) standard care in comparison to standard care alone on the incidence of SSI.Methods and analysisEPOCH consists of intraoperative high fractional inspired oxygen (0.80); goal-directed fluid therapy; active preoperative, intraoperative and postoperative warming; perioperative glucose control and treatment of severe hyperglycaemia (>10 mmoll-1) and standardised surgical site handling. Patients scheduled for elective abdominal surgery with an incision larger than 5 cm are eligible for inclusion. Participants are randomised daily, 1:1 according to variable block sizes, and stratified per participating centre to either EPOCH added to standard care or standard care only. The primary endpoint will be SSI incidence according to the Centers for Disease Control and Prevention (CDC) definition within 30 days as part of routine clinical follow-up. Four additional questionnaires will be sent out over the course of 90 days to capture disability and costs. Other secondary endpoints include anastomotic leakage, incidence of incisional hernia, serious adverse events, hospital readmissions, length of stay and cost effectiveness. Analysis of the primary endpoint will be on an intention-to-treat basis.Ethics and disseminationEthics approval is granted by the Amsterdam UMC Medical Ethics Committee (reference 2015_121). Results will be disseminated through peer-reviewed journals and summaries shared with stakeholders. This protocol is published before analysis of the results.Trial registration numberRegistered in the Dutch Trial Register: NL5572.
The addition of morphine to neuraxial anaesthesia leads to improved postoperative analgesia and lower opioid consumption, but is often accompanied by pruritus. Studies on preventing or treating ...pruritus show contradictory results. Our objective was to identify effective drugs for the prevention or treatment of pruritus by a scoping review of clinical trials. A systematic literature search was conducted in PubMed, Embase and Web of Science. We identified clinical trials investigating the prevention or treatment of neuraxial morphine-induced pruritus in adults. Systematic reviews and meta-analyses were screened for eligible studies. One-hundred-and-four articles were included covering 13 pharmacological groups. We conclude that dopamine antagonists, µ-opioid agonist/antagonists and neuraxial or orally administered µ-opioid antagonists prevent pruritus caused by neuraxial morphine regardless of the timing of administration. In the reviewed literature, 5HT3-antagonists prevent neuraxial morphine-induced pruritus when administered before morphine administration. For the treatment of neuraxial morphine-induced pruritus, only nalbuphine appears to be consistently effective. More research is needed to find the most effective doses and the optimal timing of the effective medication.
