RESUMEN
PURPOSE: Venous thromboembolism (VTE) is a common complication in critically ill patients, including severe burn cases. Burn patients respond differently to medications due to pharmacokinetic changes. This study aims to assess the feasibility and safety of different VTE pharmaco-prophylaxis in patients admitted to the ICU with severe burns. METHODS: A pilot, open-label randomized controlled trial was conducted on ICU patients with severe burns (BSA ≥ 20%). By using block randomization, patients were allocated to receive high-dose enoxaparin 30 mg q12hours (E30q12), standard-dose enoxaparin 40 mg q24hours (E40q24), or unfractionated heparin (UFH) 5000 Units q8hours. In this study, the primary outcomes assessed were the recruitment and consent rates, as well as bleeding or hematoma at both the donor and graft site. Additionally, secondary measures were evaluated to provide further insights. RESULTS: Twenty adult patients out of 114 screened were enrolled and received E30q12 (40%), E40q24 (30%), and UFH (30%). The recruitment rate was one patient per month with a 100% consent rate. Donor site bleeding occurred in one patient (16.7%) in the UFH group. On the other hand, graft site bleeding was only reported in one patient (12.5%) who received E30q12. Major bleeding happened in two patients, one in E30q12 and one in the UFH group. Five patients (25.0%) had minor bleeding; two patients (25.0%) received E30q12, two patients E40q24, and one patient UFH. RBC transfusion was needed in four patients, two on E30q12 and two on UFH. Only one patient had VTE, while four patients died in the hospital. CONCLUSION: The study observed a low recruitment rate but a high consent rate. Furthermore, there were no major safety concerns identified with any of the three pharmacologic prophylaxis regimens that were evaluated. TRIAL REGISTRATION NUMBER: NCT05237726.

INTRODUCTION: In advanced lymphedema, lymphovenous anastomosis (LVA) can be a solution based on utilizing the pressure gradient between the high pressure lymphatics and low pressure veins. If the vein pressure in high, the effect affect surgery will be less optimal. This study evaluated the effect of axillary vein perivascular scar release on LVA. MATERIALS AND METHODS: This is a retrospective study of 40 upper limb stage 2 and 3 lymphedema patients divided into 2 groups with an average follow-up of 33 months (minimal of at least 12 months); scar-released group (n=25) and control group (n=15). All patients underwent LVA with or without lymph node transfer. Demographic data, outcome (volumetric change and bioimpedence analysis (BIA)), and major veins (axillary, basilic and cephalic) diameter changes were evaluated. RESULTS: Both groups showed significant reduction in volume and BIA parameters after LVA. The scar-released groups (24/25 with lymph node transfer and 1 without) showed statistically higher reduction of BIA analysis compared to the control group at 1, 6 and 12 months after LVA. The changes in the major veins after axilla scar release showed significant changes in all 3 veins. There was a significant correlation between cephailic vein dimeter reduction and BIA measurement. CONCLUSION: The release of perivascular scar in the axially vein may result in better outcome after LVA. This is based on the finding that scar release shows correlation between cephailic vein dimeter reduction and BIA measurement suggesting reduction of venous pressure in the peripheral vein increasing the pressure gradient between the lymphatic and venous system allowing better outflow after LVA.
RESUMEN
METHODS: This study compares two methods of administration of non-alkalinised lidocaine for carpal tunnel decompression in volunteers as well as in patients undergoing carpal tunnel release: The Gale subcutaneous injection technique and another subcutaneous injection technique known as the "advancing wheal" technique. The comparison was done in nine male volunteers and in 20 patients. In the volunteer part of the study, both hands were injected and, hence, each volunteer acted as his own control. In the clinical part of the study, the 20 patients were randomised, with 10 patients receiving the Gale technique and the other 10 receiving the wheal technique. RESULTS: In volunteers, the advancing wheal technique was associated with less pain; but with a longer duration of injection and a higher number of needle pricks when compared with the Gale technique. Eight volunteers preferred the advancing wheal technique because the overall pain experience was less. One volunteer preferred the Gale technique because it took less time to complete the injection procedure. Clinically, the wheal technique also had a significantly lower mean pain score than the Gale technique. CONCLUSION: It was concluded that the advancing wheal technique is associated with less pain than the Gale technique.
