Filter by:Pre-clinic evidences showed that DEX produces antinociception by inhibiting the activation of spinal microglia and astrocyte decreasing noxious stimuli evoked release of nociceptive substances and further interrupting the spinal neuron-glia cross talk and regulating the nociceptive transmission under chronic pain condition. in this study, the analgesic efficacy of Dexmedetomidine was evaluated by a new non-invasive nociceptive index (qNOX). In this study, Anagel6000 analgesia monitor was used to quantitatively compare the analgesic efficacy of Dexmedetomidine compared with Midazolam.
To investigate the effect of intercostal blockade with and without adjuvants.
The investigators aimed to compare the block characteristics of the single operator "jedi grip" technique and the conventional double operator technique.
Locorregional anaesthesia have been increased its role in different kind of surgeries, alone or combined with general anesthesia. Due to ultrasound, peripheral nerve blocks have been increased their importance in locoregional anaesthesia. They provide excellent intraoperative and postoperative analgesia, decreasing the need for intravenous opioids which increase postoperative nausea and vomiting which may prolong hospital stay. The primary study objective is to analyze retrospectively the use of peripheral nerve blocks in the current practice of a specialized regional anaesthesia division. This is an observational, retrospective and unicenter study. 1346 patients scheduled for the surgery needed a peripheral nerve block were enrolled.
The study team aims to prospectively compare Placebo (local administration), ultrasound-guided transversus abdominis plane (UTAP) blocks, and laparoscopic-guided transversus abdominis plane (LTAP) blocks in patients undergoing robotic surgery of the prostate and kidney. The study team expects to be able to equally efficiently administer the blocks using direct visualization and ultrasound guidance. The study team expects that a negative result would obviate the need for longer operative time by eliminating the need for the separate ultrasound guided block while a positive result would demonstrate the increased utility of preoperative ultrasound blocks in managing postoperative pain.
An ultrasound-guided infraclavicular block performed with the costoclavicular (CC) approach and the lateral sagittal (LS) approach will be compared in patients scheduled for forearm and hand surgery.
The objective of this study is to compare the incidence of postoperative urinary retention related to spinal anesthesia with morphine and spinal anesthesia associated with peripheral blockade in orthopedic procedures of lower limbs. Secondary objectives are assessing the incidence of nausea and vomiting; postoperative pain and opioid consumption at 24 hours after surgery with each of the techniques. A total of 52 patients submitted to a lower limb orthopedic procedure were randomized to the intervention groups: spinal anesthesia with morphine versus spinal anesthesia without opioid associated with peripheral nerve block. After surgery, bladder ultrasound will be performed in post-anesthesia care unit to identify urinary retention and patients will be followed for 24 hours to assess outcomes.
This prospective, randomized study,control study aims to compare the analgesic effect,opioids consumption,quality of recovery,length of hospital stay，et al. between single-injection QLB(quadratus lumborum block)+ intravenous patient-controlled analgesia (IPCA) and intravenous patient-controlled analgesia (IPCA) alone in patients undergoing laparoscopic partial nephrectomy.
This prospective, randomized control study aims to compare the analgesic effect, satisfaction with anesthesia and analgesia between single-injection QLB (quadratus lumborum block)+general anesthesia (GA) and general anesthesia (GA) alone in patients undergoing laparoscopic adrenalectomy.
This study compares the tow technique of continues adductor canal block for total knee replacement surgery. Half participants will receive catheterization at the entrance of the adductor canal, while the other half will receive catheterization at the middle point of the adductor canal.
