Filter by:During the past years, a large number of clinical trials have investigated the use of the non-competitive N-methyl-D-aspartate (NMDA) receptor antagonist racemic ketamine as an adjunct to local anaesthetics, opioids, or other analgesic agents for the management and prevention of postoperative pain. Actually racemic ketamine not only abolishes peripheral afferent noxious stimulation, but can also prevent the central nociceptor sensitization. S-ketamine, one of two enantiomers of racemic ketamine, has twice the analgesic potency of the racemate. Moreover, S-ketamine shows smaller nervous system and less psychotropic effects than racemic ketamine , which may make the drug more suitable for clinical use. Recently, S-ketamine has been approved to treat refractory depression (TRD) and major depressive disorder (MDD) by the FDA .S-ketamine may have greater clinical significance due to the high rate of maternal depression. Therefore, we plan to explore whether clinical use of S-ketamine can optimize anesthesia protocol and improve maternal prognosis.
Purpose: to evaluate the efficacy and safety of erector spinal block (ESB) for analgesia in laparoscopic cholecystectomy（LC）. Method: This study is a randomized, single-blind, controlled clinical trial. Pre-operative ultrasound-guided bilateral erector spinae plane block will be performed in the ESPB group. Vertebral side block will be performed in the VSB group. And the control group will receive local anaesthesia after the surgery. Intraoperative and postoperative analgesia effect and side effects will be compared between the three groups.
The aim of this study is to better define the pharmacokinetic and pharmacodynamic profile of lorazepam for the analgosedation in pediatric intensive care unit. This will help to better define the dosages and administration modalities (bolus or continue infusion) required to achieve analgosedation with lorazepam in pediatric patients undergoing mechanical ventilation.
There is a trend that breast surgery can be done with peripheral nerve blockade and intravenous sedation, which reduces the side effects of general anesthesia such as nausea and vomiting, intubation discomfort and postoperative pain. The distribution of breast nerves is complex. Common nerve block methods are paravertebral blocks and pectoral nerve blocks. By monitoring the patient's heart rate variability change and measuring the patient's parasympathetic tone, the analgesic drug can be administered according to the patient's individual differences to avoid insufficient or excessive analgesic dose. The aim of this proposal is a prospective randomized controlled clinical trial is designed to evaluate changes in analgesia nociception index (ANI), surgical pleth index (SPI), postoperative opioid demand, and pain scores between patients who received regional anesthesia and those without in breast surgery patients under non-intubated surgery.
Pain is a vital sign that depends on personal experience involving different factors such as previous sensory and emotional experience, age, spiritual and cultural aspects, that makes it harder to evaluate, especially in young children. Pain control is important to diminish the anxiety of the child and family, also this is more important in patients who require procedure and treatment that are more painful, like oncological and hematological patients. The study aims to measure if the intranasal drugs (dexmedetomidine and fentanyl) has the same outcomes when compared with intravenous drug (ketamine and midazolam), but with less side effects. The participants are patients from an oncologic outpatient, that will be submitted to cerebrospinal fluid puncture, myelogram or both will be randomized assigned to both groups. The study will compare physiological variables ( heart rate, respiratory rate and blood pressure) and sedation and pain scales to see if its work properly. The study purpose is to evaluate if intranasal drug works in the same way with less side effects comparing with the usual treatment.
The main objective is to identify the hypoalgesic effect of the imagination of actions in sedentary subjects with high levels of physical activity.
This study aims to investigate the effect of local nasal anesthesia with lidocaine spray on the insertion of nasal tampons during active nasal bleeding.
The quadratus lumborum block is widely used in abdominal surgery for post-operative analgesia. It is now also used for pain relief after hip surgery. Under the traditional blocking method, a high concentration of long-acting local anesthetic is used in order to achieve a long-term blocking effect. However, this is also likely to cause the patient's quadriceps weakness during the block period, increasing the risk of the patient falling during rehabilitation. It also increases systemic local anesthetic poisoning and may even trigger the risk of serious side effects such as cardiac arrest. Ropivacaine is a novel long-acting topical amine anesthetics that lasts long and has anesthetic and analgesic effects. Its pharmacological characteristics are low cardiotoxicity, sensory block and motor block separation at low concentrations more obvious, and with the external peripheral vasoconstriction. Therefore, the drug is especially suitable for postoperative analgesia. Dexamethasone is a synthetic corticosteroid for the treatment of a wide range of symptoms including rheumatic diseases, certain skin diseases, severe allergies, asthma, chronic obstructive pulmonary disease, cerebral edema, and may also be combined with antibiotics for tuberculosis patients. It is becoming more common to use steroids as an adjuvant to local anesthetics in peripheral nerve block. Steroids have neurological blockade effects by blocking the nociceptive transmission of pith-type C-fibers and inhibiting the release of ectopic neurons. Dexamethasone, as a local anesthetic adjuvant in peripheral nerve block, has also been widely studied recently. In order to reduce the incidence of long-acting topical anesthetics from the nerve block in the quadratus lumborum block, reducing the local anesthetic concentration is a feasible method. However, this will also result in a shorter time to neurological block. The investigators hypothesized that the addition of Dexamethasone 5 mg to low concentrations (0.25%) of Ropivacaine would prolong postoperative analgesia. Therefore, the purpose of this study was to compare the postoperative analgesia and the side effects of postoperative quadratus lumborum block with the addition of Dexamethasone 4mg to Ropivacaine (0.25%) in low concentrations and Ropivacaine (0.5%) alone.
We evaluated the clinical effect of Butorphanol on postoperative analgesia by observing the vital signs of patients, general condition of newborns and pain assessment.
The study aims to evaluate the efficacy of pericapsular nerve group block versus fascia iliaca block in reducing post operative pain within the first 24 hours following hip arthroscopy
