Filter by:Neuromuscular blocking agents (NMBAs) are frequently used in anesthesia and quantitative neuromuscular monitoring is standard care. The TOF WATCH SX® monitor is considered as one of the reference monitoring devices in clinical research and clinical practice. With this monitor the ulnar nerve is stimulated at the wrist and the force of the movement of the thumb is measured with acceleromyography. This method requires freedom of movement of the patient's thumb. Unfortunately this is not always possible due to the constraints of patient positioning during the operation. The TOF Cuff® monitor is a modified non-invasive blood pressure cuff that incorporates stimulating electrodes in its inner surface and is based on the stimulation of the peripheral nerve in the arm (brachial plexus, ulnar and median nerves principally). The evoked neuromuscular activity is recorded through the changes in pressure generated in the inner part of the cuff by the muscular activity after the stimulus. Moreover, this device can be used for non-invasive reading of the blood pressure. This device has been validated with mechanomyography, but was never been compared with acceleromyography, which is the most common used neuromuscular monitoring method.
The proposed study will use qualitative methodology to understand health care provider perceptions of neuromuscular blockade (NMB) in patients with Acute Respiratory Distress Syndrome (ARDS). To achieve this goal the investigators will conduct a prospective ancillary study at four clinical centers participating in the NHLBI PETAL network as part of the ROSE (Reevaluation of Systemic Early Neuromuscular Blockade) clinical trial (NCT02509078). Using thematic content analysis of semistructured interviews with health care providers caring for patients enrolled in the ROSE trial the investigators will determine the barriers to NMB use and develop a framework for future NMB adoption in ARDS.
This prospective, randomized, double blinded study is intended to enroll a total of 92 patients undergoing thoracic surgery with general endotracheal anesthesia at Parkland Hospital. Patients will be randomized to receive either neostigmine or sugammadex for reversal of neuromuscular blockade. Merck, Inc. will supply the sugammadex through an agreement with Parkland Investigational Drug Services. Neostigmine is readily available for anesthesiologists to use and is the current standard of care for reversal of neuromuscular blockade. A standardized anesthetic protocol that is usual and customary for the type of operation the patient is having will be provided to the anesthesia teams of enrolled subjects. The remainder of the anesthetic care of the subject will not deviate from the standard of care. The surgeon, anesthesia team, postoperative recovery nurse, and research assistant will be blinded as to which reversal drug the patient receives. The only individual that will know to which drug the patient has been randomized will be the pharmacist who draws up the medication(s). A blinded research assistant will record postoperative outcomes and the patient will be followed 90 minutes postoperatively for any adverse events.
A reversal agent is commonly given to improve neuromuscular function after intra-operative administration of non-depolarizing neuromuscular blocking agents. The administration of conventional reversal agent neostigmine is associated with many undesirable side effects. For almost a decade, a new novel drug sugammadex has been used to specifically antagonize the effect of aminosteroidal neuromuscular blocking agents. A total of 80 paediatric patients planned for general anaesthesia were divided into two groups and were given either neostigmine+atropine, or sugammadex for reversal once the operation had completed.
The NMB (Neuromuscular Blockade) is the most frequent complication in anesthesiology associated with an increase in adverse respiratory events in the postoperative period. Its appearance depends on multiple factors. The introduction of a comprehensive educational strategy aimed at promoting the proper management of NMB in the intraoperative period and a package of measures that must be performed (intraoperative neuromuscular monitoring and reversal of the effect of neuromuscular blockers) may contribute to a decrease in the incidence of NMB, Increase safety in the surgical patient and decrease associated costs.
Acceleromyography (AMG) is the most wide spread used method to assess neuromuscular block during anesthesia. However AMG is known to be inaccurate when compared to the gold standard in neuromuscular transmission monitoring, electromyography (EMG). Furthermore when the patients arms require to be positioned next to the body and beneath surgical drapes, AMG measurements are often hindered and inaccurate. The TOF cuff is a new device which measures neuromuscular blockade at the upper arm with a blood pressure cuff. It overcomes the previously mentioned disadvantages of AMG. However, it validity compared to EMG and AMG has not yet fully been investigated. This study aims to compare the bias, limits of agreement and precision of the Train-of-Four cuff relative to AMG and EMG during recovery of moderate and deep neuromuscular block in patients with normal body mass index and morbidly obese patients.
In retrospective data search the investigators will identified the percentage of patients with muscle relaxants administered during perioperative period. The block reversal, typ of drug, percentage of cases with and without reversal will be identified.
Transurethral resection of the bladder tumor (TURB) for bladder tumor excision is the mainstream treatment. However, the beneficial effects of sugammadex after general anesthesia for TURB have not been thoroughly evaluated. Investigators hypothesized that deep NMB and the use of sugammadex as a reversal agent may be associated with better endoscopic surgical condition and recovery profile compared with moderate NMB during TURB. This study was designed to compare patients with deep neuromuscular blockade (NMB) with moderate NMB during transurethral resection of the bladder tumor (TURB) in terms of surgical condition and postoperative recovery.
The aim of this prospective, observational study is to determine the incidence of post-operative residual neuromuscular blockade (PRNB) in patients undergoing intra-abdominal procedures compared to patients undergoing other noncardiac/non intra-thoracic procedures that also require non-depolarizing neuromuscular blocking agents (NMBA) administration. As intra-abdominal surgeries are independently associated with post-operative pulmonary complications (PPCs), it is important to highlight other factors, such as PRNB, that could contribute to these complications.Although it has been shown that the risk of adverse respiratory events can be reduced by intra-operative quantitative neuromuscular monitoring, such monitoring is not in widespread use.This study will incorporate quantitative monitoring in the post-anesthesia care unit (PACU) setting by using the Stimpod NMS450® in an effort to show a disparity in the incidence of residual paralysis between these two patient populations and to emphasize the need to implement more accurate neuromuscular monitoring, especially for those that are already at increased risk for respiratory complications.
The aim of this study is to evaluate the treatment effect of magnesium sulfate on the T4 / T1 ratio after reversal with sugammadex deep or moderate neuromuscular blockade induced by rocuronium.
