Effect of Dexmedetomidine on Microsurgery Reconstruction in Cancer Patient

This double-blinded randomized controlled trial aims to investigate the effect of intraoperative dexmedetomidine administration on early flap viability and microvascular integrity in cancer patients undergoing elective microvascular reconstructive surgery. The primary outcome is clinical flap viability within 48 hours postoperatively, assessed using a standardized scoring system based on flap color, temperature, capillary refill time, and tissue turgor. Secondary outcomes include the evaluation of biomarkers related to endothelial glycocalyx degradation (syndecan-1), oxidative stress (SOD-1), inflammation (IL-6, IL-10), thrombosis (PAI-1), and angiogenesis (VEGF), as well as microcirculatory assessment using Sidestream Dark Field (SDF) imaging. The study is designed to determine whether dexmedetomidine improves early surgical outcomes by modulating pathophysiological processes involved in microvascular flap success.

Anterolateral Tigh (ALT) Flaps Oxygenation Monitoring by NIRS

The goal of this observational study is to conduct postoperative monitoring in patients who have undergone upper or lower limb reconstructive surgery with an anterolateral thigh flap, by employing the gold standard approach: intermittent assessment of clinical parameters (flap's color, temperature, skin turgor and capillary refill time) combined with Doppler techniques, alongside continuous tissue oxygenation measurements obtained using the CASMED FORE-SIGHT ELITE monitor.The main objective of the study is to provide preliminary data on potential cut-off values indicative of flap failure.

This Study Aims to Explore the Efficacy of Hyperbaric Oxygen in the Treatment of Flap Ischaemic Necrosis After Breast Cancer Surgery

The expectation of our study was to explore the efficacy of using hyperbaric oxygen to rescue flap ischaemic necrosis after breast cancer surgery.
