Effect of pneumatic leg compression on post-induction hypotension in elderly patients undergoing robot-assisted laparoscopic prostatectomy: a double-blind randomised controlled trial

Post-induction hypotension is common and associated with postoperative complications. We hypothesised that pneumatic leg compression reduces post-induction hypotension in elderly patients undergoing robot-assisted laparoscopic prostatectomy. In this double-blind randomised study, patients were allocated randomly to the pneumatic leg compression group (n = 50) or control (n = 50). In the intervention group, pneumatic leg compression was initiated before induction of anaesthesia. In the control group, pneumatic leg compression was initiated 20 min after anaesthesia induction. The primary outcome was the incidence of post-induction hypotension in these groups. Post-induction hypotension was defined as systolic blood pressure < 90 mmHg during the first 20 min after induction. Haemodynamic variables and area under the curve of post-induction systolic blood pressure over time were assessed. Complications associated with pneumatic leg compression were recorded, including: peripheral neuropathy; compartment syndrome; extensive bullae beneath the leg sleeves; and pulmonary thromboembolism. The incidence of post-induction hypotension decreased in the pneumatic leg compression group compared with that in the control group; 5 (10%) vs. 29 (58%), respectively, p < 0.001. In the pneumatic leg compression group, the lowest systolic, diastolic and mean blood pressures 20 min after induction of anaesthesia were significantly greater than the control group. Pneumatic leg compression resulted in an increased area under the curve of systolic blood pressure in the first 20 min after induction, p = 0.001. There were no pneumatic leg compression-related complications. Pneumatic leg compression reduced post-induction hypotension in elderly patients undergoing robot-assisted laparoscopic prostatectomy, suggesting that it is an effective and safe intervention to prevent post-induction hypotension among elderly patients undergoing general anaesthesia.     

Evaluation of timolol maleate gel for management of hard-to-heal chronic venous leg ulcers. Phase II randomised-controlled study

BackgroundVenous leg ulcers (VLUs) often take a very long time to heal. Timolol maleate has been reported as displaying efficacy in healing of VLUs.ObjectivesTo evaluate the efficacy of timolol maleate gel in the management of hard-to-heal VLUs and to assess its safety as a topical agent during 12 weeks of use in combination with conventional treatment.MethodsA prospective, phase-II randomised-controlled trial with a sample size based on Fleming's one-stage design (P0 = 0.25, P1 = 0.45, alpha = 0.1, beta = 0.2) was planned. Patients with VLUs present for ≥ 24 weeks and with ≥ 50% granulation tissue were included. One drop of sustained-release timolol gel (Timoptol® LP 0.5%, Santen, Tampere, Finland) per 6 cm² VLU area was applied every 2 days for 12 weeks in timolol-treated patients, as adjuvant therapy to the standard care protocol (interface dressing and multilayer venous compression). Controls received standard care alone. The primary endpoint was to obtain ≥ 40% reduction in ulcer area at week 12 (W12).ResultsForty-three patients were randomised to the study, with 40 receiving at least one treatment and included in the analysis: 21 timolol-treated patients and 19 controls (females: 70%; median age: 72.5 [range 35–93] years). At W12, ≥ 40% ulcer-area reduction was achieved in 14/21 (67%) timolol-treated patients vs. 6/19 (32%) controls. No serious adverse events occurred. Local wound infections not requiring systemic antibiotics occurred in 5 cases in the timolol group and in one case in the controls.ConclusionsThese results support the benefit and safety of using timolol maleate to manage hard-to-heal VLUs, but confirmation is required in a larger multicentre randomised phase-III study.     

Development of a core outcome set for venous leg ulceration (CoreVen) research evaluations (protocol)

BackgroundA venous leg ulcer is a chronic leg wound caused by poor venous blood circulation in the lower limbs. It is a recurring condition causing pain, malodour, reduced mobility, and depression. Randomised controlled trials evaluating treatments for venous leg ulcers provide important evidence to inform clinical decision-making. However, for findings to be useful, outcomes need to be clinically meaningful, consistently reported across trials, and fully reported. Research has identified the large number of outcomes reported in venous leg ulcer trials, impacting both synthesis of results, and clinical decision-making. To address this, a core outcome set will be developed. A core outcome set is an agreed standardised set of outcomes which should be, as a minimum, measured and reported in all trials which evaluate treatment effectiveness for a given indication. A core outcome set has the potential to reduce research waste, improve the utility of RCTs, reduce reporting bias, facilitate treatment comparisons across different sources of evidence and expedite the production of systematic reviews, meta-analyses and evidence-based clinical guidelines.AimThe aim of this project is to develop a core outcome set for research evaluating the effectiveness of interventions for treating venous leg ulceration.MethodsThrough a scoping review of the literature on venous leg ulceration, we will firstly identify a list of candidate outcome domains (broad categories in relation to what is being measured) from randomised controlled trials and qualitative research, and outcomes (specific methods in relation to what is being measured). In two further stages, we will use the resulting lists of outcome domains and outcomes to design two online surveys. A range of stakeholders will be invited to participate in the surveys and they will be asked to indicate which outcome domains and outcomes are most important and should be considered as core in future research reports.     

Education in people with venous leg ulcers based on a brochure about compression therapy: A quasi‐randomised controlled trial

Brochures are a useful supplement to patient education. There is increasing evidence that they are an effective medium to support patient satisfaction, adherence, and empowerment. This study aims to produce reliable data on how much patients with venous leg ulcer (VLU) may profit from a brochure that focuses on VLU and on measures and aims of the related compression therapy. The evaluation took part from October 2018 until March 2019 and included 136 patients with VLU and related compression therapy. They were randomly sorted into a case group and a control group of 68 patients each. The case group received a brochure about venous disease and compression therapy and filled in a questionnaire after reading. The questions ranged from basic knowledge about VLU and compression therapy to aspects of self‐care. The control group answered the same questions without previous reading of the brochure. The results show that in almost every aspect, the patients in the case group were better informed about their diseases, the compression therapy, and how they may support the measures adequately. This study suggests that patients with VLU may profit from a brochure that explains their disease and the related compression therapy. Better knowledge and understanding may strengthen their empowerment and adherence.     

Participant experiences in a feasibility trial of supervised exercise training in adults with venous leg ulcers: A qualitative study

Exercise training can improve lower‐limb cutaneous microvascular reactivity in adults with venous leg ulceration; however, there is a lack of research on patients' views about the acceptability and feasibility of exercise interventions. The aim of this study was to explore participants' experiences of the trial “Exploring the Feasibility of Implementing a Supervised Exercise Training and Compression Hosiery Intervention in Patients with Venous Ulceration” (FISCU). Semi‐structured face‐to‐face and telephone interviews were used to investigate participants' experiences (n = 16) of taking part in the FISCU trial. Data were analysed using thematic analysis. Three overarching themes were identified, along with 11 sub‐themes: (a) sedentary cautious living (because of pain and reduced mobility, treatment and perceived control, and advice to rest and be careful), (b) key components of the exercise trial (including motivation, an individualised intervention supervised by a specialist exercise professional, and satisfaction with the intervention), and (c) benefits of exercise (physical benefits and healing, psychological well‐being, positive impact on comorbidities, and an improved self‐management strategy). This study found that an exercise intervention was viewed by participants as positive, acceptable, and feasible while living with a venous leg ulcer. An individualised and supervised exercise programme was key to build confidence to exercise.

Effectiveness of combined conventional treatment with a tailored exercise training program on wound healing in patients with venous leg ulcer: A randomized controlled trial

IntroductionVenous leg ulcer (VLU) is a therapeutic challenge. The mainstay of care is compression therapy and wound care. Exercise is also recommended for facilitating wound healing. This study aimed to determine whether adding tailored exercise training to conventional treatment would be superior on wound healing, ankle mobility, calf muscle function, and functional ability compared to those with the conventional treatment alone.MethodsA randomized controlled trial, single-blinded was conducted. VLU patients were randomized to the conventional treatment plus tailored exercise training (intervention group) and the conventional treatment alone (control group) (12/group). The conventional treatment contained foam dressing and short-stretch bandage, while the tailored exercise training consisted of stretching, resistive, and aerobic exercise sessions (3-day/week, for 12-week). Primary outcomes included healing rate and wound size parameters. Secondary outcomes were ankle range of motion (ROM), calf circumference, calf muscle endurance and strength, and functional ability. All outcomes were assessed at baseline, 6-, and 12-week intervention.ResultsThe intervention group had a higher trend of healing rate after 12-week training than those in the control group, but this trend was not significantly different (92% versus 58%, p = 0.06). After training, the intervention group had significantly decreased wound size. The intervention group had significantly higher ankle ROM and dorsiflexor muscle strength after 6- and 12-week training than those in the control group.ConclusionAdding the tailored exercise training incorporated with the conventional treatment may provide a greater tendency on wound healing and have the potential to improve ankle mobility than the conventional treatment alone.Trial registration numberTCTR20170405002.
