Abstract Background: Intravenous patient-controlled analgesia (IV-PCA) is well applied in postoperative period. However, determining an appropriate opioid dose was difficult. A previous study suggested the usefulness of variable-rate feedback infusion. In this study, we used a dual-channel elastomeric infusion pump to provide changes in PCA infusion rate by pain feedback.Methods: 90 patients of ASA I-III and 65 to 79 years undergoing orthopedic surgery were participated in the study. All patients were applied a dual-chamber PCA. Patients were randomly allocated into treatment group (Group D; PCA drugs were divided into both chambers.) or control group (Group C; PCA drugs were contained only in the constant flow chamber, but normal saline was contained in the adjustable flow chamber.) The primary outcome was the amount of fentanyl consumption via PCA bolus. The secondary outcome variables were pain score, total fentanyl consumption, rescue analgesic use, patient satisfaction, recovery scores and adverse events including postoperative nausea and vomiting (PONV).Results: Group D showed decreased fentanyl consumption in PCA bolus. Moreover, group D showed in a decrease in rescue analgesic use and better patient satisfaction. The incidence of PONV was much higher in group C. There was no difference in other adverse events.Conclusions: We showed the usefulness of dual chamber IV-PCA to change the flow rate to the pain feedback without any complication. Our results suggested noble implications that may improve existing IV-PCA equipment.Clinical trial registration: The study registered at UMIN clinical trial registry (registered date: 05/03/2020, registration number: UMIN000039702).

Patients undergoing laparoscopic gynecologic surgery and receiving postoperative analgesia with opioids have a high risk of postoperative nausea and vomiting (PONV). We compared the antiemetic efficacy of three doses of ramosetron in this high-risk population. In this prospective, double-blind trial, 174 patients randomly received ramosetron 0.3 mg (R0.3 group; n = 58), 0.45 mg (R0.45 group; n = 58), or 0.6 mg (R0.6 group; n = 58) at the end of surgery. The primary outcome was the incidence of PONV during the first postoperative 48 h. Nausea severity, pain scores, adverse events, and patient satisfaction (1–4; 4, excellent) were assessed. The incidence of PONV was not different between groups (35%, 38%, and 35% in R0.3, R0.45, and R0.6 groups; p = 0.905). Nausea severity, pain scores, and incidence of adverse events (dizziness, headache, or sedation) were similar between groups. Compared to the R0.3 group, the R0.45 and R0.6 groups had lower incidence of premature discontinuation of fentanyl-based patient-controlled analgesia primarily because of intractable PONV (9% and 5% vs. 24%; p = 0.038), and higher satisfaction scores (3.4 ± 0.8 and 3.3 ± 0.7 vs. 2.4 ± 0.9; p = 0.005). Compared to ramosetron 0.3 mg, ramosetron 0.45 and 0.6 mg did not reduce PONV, but reduced premature discontinuation of patient-controlled analgesia and increased patient satisfaction, without increasing adverse events.

Abstract Background: A newly designed intravenous patient-controlled analgesia (PCA) device with dual-channel elastomeric infusion pump has been recently introduced. One channel is a continuous line with a constant flow rate basal infusion, while the other channel has an adjustable flow rate and bolus function, and is labeled as a selector-bolus channel. This study compared dual and single channel intravenous PCA in terms of clinical effect and quality of recovery.Methods: Eighty-four patients undergoing total laparoscopic hysterectomy were randomly allocated to a 1-channel group (n = 41) or a 2-channel group (n = 43). Only the selector-bolus channel was utilised, but the continuous channel was not utilised in the 1-channel group, but both channels were utilised in the 2-channel group. In the 1-channel group, 16 µg/kg fentanyl, 2 mg/kg ketorolac, and 12 mg ondansetron with normal saline was administered to the selector-bolus channel, and normal saline only in the continuous channel for blinding. In the 2-channel group, 16 µg/kg fentanyl was administered to the selector-bolus channel, and ketorolac (2 mg/kg) and ondansetron (12 mg) were administered via the continuous channel. The quality of recovery was evaluated preoperatively and 24 h postoperatively using the Quality of Recovery-40 (QoR-40). Cumulative PCA consumption, postoperative pain rated using the numeric rating scale (NRS; during rest/cough), and postoperative nausea were evaluated 6, 12, 24, 36, and 48 hours after surgery. Incidence of vomiting and use of antiemetics and rescue analgesics were measured.Results: The 24-h postoperative QoR-40 score was higher in the 2-channel group than in the 1-channel group (P=0.031). The incidence of nausea at 12 h and 36 h was significantly higher in the 1-channel group (P=0.043 and 0.040, respectively), and antiemetic use was more frequent in the 1-channel group (P=0.049). Patient satisfaction was higher in the 2-channel group (P=0.036). No significant differences were observed in pain scores during resting/cough or cumulative PCA consumption.Conclusions: The 2-channel PCA showed a lower incidence of nausea and antiemetics administration, and consequently higher overall patient satisfaction and quality of recovery with comparable analgesic efficacy to that of the 1-channel PCA after total laparoscopic hysterectomy.Trial registration: Registered at ClinicalTrials.gov, NCT04082039 on 9 September 2019.

Abstract Background Post-operative pulmonary complications (PPC) can develop in up to 13% of patients undergoing neurosurgical procedures and may adversely affect clinical outcome. The use of intraoperative lung protective ventilation (LPV) strategies, usually including the use of a low Vt, low PEEP and low plateau pressure, seem to reduce the risk of PPC and are strongly recommended in almost all surgical procedures. Nonetheless, feasibility of LPV strategies in neurosurgical patients are still debated because the use of low Vt during LPV might result in hypercapnia with detrimental effects on cerebrovascular physiology. Aim of our study was to determine whether LPV strategies would be feasible compared with a control group in adult patients undergoing cranial or spinal surgery. Methods This single-centre, pilot randomized clinical trial was conducted at the University Hospital “Maggiore della Carità” (Novara, Italy). Adult patients undergoing major cerebral or spinal neurosurgical interventions with risk index for pulmonary post-operative complications > 2 and not expected to need post-operative intensive care unit (ICU) admission were considered eligible. Patients were randomly assigned to either LPV (Vt = 6 ml/kg of ideal body weight (IBW), respiratory rate initially set at 16 breaths/min, PEEP at 5 cmH2O and application of a recruitment manoeuvre (RM) immediately after intubation and at every disconnection from the ventilator) or control treatment (Vt = 10 ml/kg of IBW, respiratory rate initially set at 6–8 breaths/min, no PEEP and no RM). Primary outcomes of the study were intraoperative adverse events, the level of cerebral tension at dura opening and the intraoperative control of PaCO2. Secondary outcomes were the rate of pulmonary and extrapulmonary complications, the number of unplanned ICU admissions, ICU and hospital lengths of stay and mortality. Results A total of 60 patients, 30 for each group, were randomized. During brain surgery, the number of episodes of intraoperative hypercapnia and grade of cerebral tension were similar between patients randomized to receive control or LPV strategies. No difference in the rate of intraoperative adverse events was found between groups. The rate of postoperative pulmonary and extrapulmonary complications and major clinical outcomes were similar between groups. Conclusions LPV strategies in patients undergoing major neurosurgical intervention are feasible. Larger clinical trials are needed to assess their role in postoperative clinical outcome improvements.

Background: There is currently no optimal method for cartilage restoration in large, full-thickness cartilage defects in older patients. Purpose: To determine whether implantation of a composite of allogeneic umbilical cord blood–derived mesenchymal stem cells and 4% hyaluronate (UCB-MSC-HA) will result in reliable cartilage restoration in patients with large, full-thickness cartilage defects and whether any clinical improvements can be maintained up to 5 years postoperatively. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: A randomized controlled phase 3 clinical trial was conducted for 48 weeks, and the participants then underwent extended 5-year observational follow-up. Enrolled were patients with large, full-thickness cartilage defects (International Cartilage Repair Society [ICRS] grade 4) in a single compartment of the knee joint, as confirmed by arthroscopy. The defect was treated either with UCB-MSC-HA implantation through mini-arthrotomy or with microfracture. The primary outcome was proportion of participants who improved by ≥1 grade on the ICRS Macroscopic Cartilage Repair Assessment (blinded evaluation) at 48-week arthroscopy. Secondary outcomes included histologic assessment; changes in pain visual analog scale (VAS) score, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and International Knee Documentation Committee (IKDC) score from baseline; and adverse events. Results: Among 114 randomized participants (mean age, 55.9 years; 67% female; body mass index, 26.2 kg/m2), 89 completed the phase 3 clinical trial and 73 were enrolled in the 5-year follow-up study. The mean defect size was 4.9 cm2 in the UCB-MSC-HA group and 4.0 cm2 in the microfracture group ( P = .051). At 48 weeks, improvement by ≥1 ICRS grade was seen in 97.7% of the UCB-MSC-HA group versus 71.7% of the microfracture group ( P = .001); the overall histologic assessment score was also superior in the UCB-MSC-HA group ( P = .036). Improvement in VAS pain, WOMAC, and IKDC scores were not significantly different between the groups at 48 weeks, however the clinical results were significantly better in the UCB-MSC-HA group at 3- to 5-year follow-up ( P < .05). There were no differences between the groups in adverse events. Conclusion: In older patients with symptomatic, large, full-thickness cartilage defects with or without osteoarthritis, UCB-MSC-HA implantation resulted in improved cartilage grade at second-look arthroscopy and provided more improvement in pain and function up to 5 years compared with microfracture.

Background:Secukinumab was approved by NICE for patients with active Ankylosing Spondylitis and Psoriatic Arthritis in 2017. Clinical trial data suggests secukinumab is a useful treatment option in both conditions, but often real world experience differs greatly from clinical trial results. In addition, patients with more refractory disease are often excluded from clinical trials.Objectives:To assess the response to secukinumab in patients with seronegative spondyloarthropathy receiving treatment at University Hospital Coventry and WarwickshireMethods:Patients starting secukinumab at UHCW were identified from the Blueteq funding database. Medical notes were reviewed retrospectively to assess response rates using BASDAI responses in Ankylosing spondylitis and PsARC responses in PsA. Patients who had previously had inadequate response to TNF inhibitors (PsA only) and severe psoriasis received 300mg secukinumab monthly; the remainder were prescribed 150mg monthly.Results:146 patients commenced secukinumab between June 2017 and January 2020 and had outcome data recorded. 73 patients (50%) had received previous biologic agents prior to secukinumab exposure. Patients with Ankylosing spondylitis had high BASDAI (6.8±1.4) and spinal pain (7.5±1.4). 48 patients had an initial response to treatment as per outcome measures done before and after Secukinumab inception. Secukinumab was effective in 89 patients (94%), and 87 (91%) continued treatment.In psoriatic arthritis, despite high levels of activity at baseline (mean tender joint count 10±8; swollen joint count 6±3) and 65% prior biologic exposure; high rates of response were seen. The majority of patients have continued treatment. Secukinumab was well tolerated in both patient groups with low rates of discontinuation due to adverse events (8 patients, 5%). Adverse events included recurrent infection (3), rash (1), mouth ulcers (1), vertigo (1), new onset cancer (1) and new onset Crohn’s (1) although rates were low overall.

Objectives: Perfusion and blood oxygen levels are frequently insufficient in patients with hard-to-heal wounds due to poor circulation, vascular disruption and vasoconstriction, reducing the wound's capacity to heal. This study aimed to investigate the effect of topical oxygen on healing rates in patients with hard-to-heal diabetic foot ulcers (DFUs) (i.e., non-responsive over four weeks). Method: This multicentre, open-label, community-based randomised clinical trial compared standard care (SOC) with or without continuous topical oxygen therapy (TOT) for 12 weeks in patients with DFUs or minor amputation wounds. SOC included debridement, offloading with total contact casting (TCC) and appropriate moisture balance. Primary endpoints were the number of patients to achieve complete wound closure and percentage change in ulcer size. Secondary endpoints were pain levels and adverse events. Results: For the study, 145 patients were randomised with index ulcers graded Infectious Diseases Society of America (IDSA) 1 or 2, or Wagner 1 or 2. In the intention-to-treat analysis, 18/64 (28.1%) patients healed in the SOC group at 12 weeks compared with 36/81 (44.4%) in the SOC plus TOT group (p=0.044). There was a statistically significant reduction in wound area between the groups: SOC group mean reduction: 40% (standard deviation (SD) 72.1); SOC plus TOT group mean reduction: 70% (SD 45.5); per protocol p=0.005). There were no significant differences in changes to pain levels or adverse events. Conclusion: This study suggests that the addition of TOT to SOC facilitates wound closure in patients with hard-to-heal DFUs.
