Active clinical trials for "Agnosia"

The aim of this study is to study the analgesic efficacy of a continuous infusion of local anaesthetics for interscalene brachial plexus block after major shoulder surgery in the setting of multimodal analgesia, in order to determine whether the use of a catheter is still necessary in a contemporary practice.

This is a multi-center, randomized, two-stage, phase II clinical study .The main objective is to evaluate the safety and tolerability of HSK21542 injection for analgesia in patients undergoing colonoscopy, and, combining the pharmacodynamic (PD) and pharmacokinetic (PK) characteristics

Objective of study: To compare the efficacy of intravenous paracetamol and fentanyl for intra-operative and post-operative pain relief in patients undergoing diagnostic and therapeutic hysteroscopy. Hypothesis of study: There is no difference in pain control between intravenous fentanyl and paracetamol in patients undergoing hysteroscopy.

The aim of this study is to evaluate analgesic effect of ultrasound-guided retrolaminar block vs ultrasound-guided thoracic epidural analgesia in pain control following laparoscopic cholecystectomy.

Pain control after hip replacement surgery is important to ensure patient comfort, allow mobilisation, and aid recovery. The investigators propose a simple and pragmatic study comparing two different anaesthetic techniques in the provision of pain relief after hip surgery. Patients will be randomised to receive either spinal anaesthesia containing morphine or spinal anaesthesia without morphine and an ultrasound guided fascia iliaca nerve block. Although morphine is an effective pain killer, its side effects include itch, urinary retention, nausea and potentially fatal breathing problems. If the nerve block can be shown to provide comparable pain relief to spinal morphine, then morphine could be removed from the spinal injection. This could reduce side effects and improve patient safety. The investigators wish to investigate whether ultrasound guided fascia iliaca plane block provides analgesia which is comparable to that of intrathecal opioid for primary hip arthroplasty in the first 24 hours after hip replacement surgery

This prospective, comparative and double blind study is aimed to determine if normal saline or dextrose 5% in water will modify the stimulation during the insertion of the stimulating catheter used for continuous femoral and sciatic blocks in total knee replacement.

This study assesses efficacy of scalp block and Ultrasound guided transverse abdominis plane (TAP) block with 1µg/kg clonidine as adjuvant to 0.2% ropivacaine versus intravenous fentanyl (0.1µg/kg/hr) on intraoperative hemodynamics and perioperative analgesia in abdominal bone flap cranioplasties (ABFC).

This study aimed to compare the effects of three commonly used combination doses on the onset time and adverse reactions.

The main objective of the study is to demonstrate the efficacy of Dexmedetomidine on the prolongation of analgesia obtained by interscalenic bloc of the brachial plexus and intravenous injection of Dexamethasone (efficacy objective).

The aim of this study is to evaluate analgesic effects Bupivacaine, Bupivacaine plus Dexmedetomidine and Bupivacaine plus Fentanyl in relieving pain after knee arthroscopic surgery.
