Filter by:This is an adaptative study where each participant's rocuronium dose will depend on the previous patient's response, being higher if it was not enough and lower if it was more than enough.
Pars plana vitrectomy is usually performed under general anesthesia including endotracheal intubation and muscle relaxation. However, for short procedures anesthesia using a laryngeal mask without muscle relaxation is also common in practice. In this observational study the incidence of patient movement will be examined between these anesthesia techniques.
The objective of this study is to assess the performance of acceleromyography as a method of evaluation of muscle relaxation after application of tetanus stimulation to obtain stability of responses before administration of neuromuscular blocking agents.
The primary objective of the current study is to compare intraoperative respiratory mechanics in patients receiving laparoscopic renal surgery under deep neuromuscular blockade (dNMB) and under moderate neuromuscular blockade (mNMB). In addition, we will compare intraoperative hemodynamics and postoperative pulmonary function between the two groups.
The study examines the clinical application of TOF (train of four test) used by anesthesiologists and neurophysiologists during instrumented spine procedures, as well as certain associated parameters. 'Train of four' test is a test routinely used during the surgery, which is performed by stimulation of peripheral nerve with purpose to determine the degree of muscle relaxation by interpretation of muscle response. During spine surgery, it is helpful for the surgeon to have a patient's muscles as relaxed as possible with the least amount of tone, especially when exposing. Anesthesiologists achieve this level of relaxation by giving a neuromuscular blocking agent. If medication given to do this has not fully left their system by the time the surgeon needs to start putting in the screws and rods, then the intraoperative monitoring can not be adequately performed. If the muscles are too relaxed, then free run EMG and screw stimulation, two monitoring methods used, will not be analyzed correctly and the surgery may be adversely affected. This study compares the results of the 'train of four' test performed by neurophysiologists and anesthesiologists. Additionally, it looks at the differences, if any, in comparing stimulation of the foot nerve (tibial n.) or hand nerve (ulnar n.) Performing the TOF (train of four test) in the lower extremity can be relevant for many reasons. Train of four tests can show the presence of four twitches in the arms but the legs may not fully recovered from muscle relaxant given by anesthesia. Also, train of four test which uses subjective method of interpretation by anesthesiologists may present different results compared than objective quantitative method of train of four test interpretation. Ultimately, the goal of this study is to show the importance of 'TOF' testing in ensuring that any identifiable preventable intraoperative surgical complication is appropriately identified.
The objective of this study is to compare the value of deep neuromuscular block (NMB) (using rocuronium) in laparoscopy versus high dose opioids (using remifentanil) or 1 minimum alveolar concentration (MAC) inhalation (using sevoflurane) for the surgeon. The study hypothesis is that laparoscopic workspace is larger when using rocuronium versus opioids or inhalation. Laparoscopic workspace is measured as the abdominal compliance and the pressure at volume zero (PV0) using the abdominal pressure volume relation. Three points allow to calculate the abdominal compliance and the pressure at zero volume (PV0).
Muscle relaxants are drugs providing muscle relaxation during surgical treatment. Previous studies have shown that males and females respond differently to this kind of drug. Our hypothesis is that males are more sensitive to the effect of Mivacurium (a muscle relaxant) than females, meaning that males need a lower blood concentration of the drug than females in order to obtain a given effect.
The researchers want to investigate the effects of muscle relaxation with rocuronium bromide during general anaesthesia on muscle trauma (serum CK, CRP) and postoperative analgesic consumption in patients with total hip prosthesis replacement (general vs. spinal anaesthesia).
The purpose of this study is to evaluate the efficacy, pharmacokinetics, and safety of Org 9426 in maintenance of muscle relaxation in adult subjects undergoing general elective surgery.
