Filter by:Magnesium sulphate is regularly used in perioperative medicine. During and after general anesthesia, it enhances the effect of muscle relaxants because it reduces the liberation of acetylcholine at the neuromuscular junction. When administered immediately after spontaneous recovery of a neuromuscular block (NMB), magnesium may cause a recurrence of NMB and compromise patient safety. Rocuronium is a neuromuscular blocking agent which is frequently used to facilitate intubating and surgical conditions. At the end of the procedure, there are two ways to accelerate the reversal of a neuromuscular block induced by rocuronium: 1. Administration of neostigmine, an anticholinesterase agent and competitive antagonist; 2. Administration of sugammadex, a γ-cyclodextrin compound and specific encapsulator of rocuronium. The study is done in patients receiving rocuronium and either neostigmine or sugammadex for reversal of NMB. It is hypothesized that when sugammadex is used as an antagonist of a rocuronium-induced NMB, it prevents the reappearance of NMB when magnesium is injected, because sugammadex should inactivate all remaining rocuronium molecules and restore neuromuscular reserve of the neuromuscular junctions. Further more it is hypothesized that reversal with neostigmine will not prevent a magnesium-induced recurrence of NMB to the same extent. The primary objective of the study is to show that after reversal with sugammadex there is no or only very little re-occurrence of neuromuscular block after a magnesium perfusion. Furthermore we want to show that after reversal with neostigmine there is a re-occurrence of neuromuscular block.
Comparison of the impact of a deep neuromuscular blockade (TOF count = 0 and posttetanic count [PTC] 1-2) and a moderate neuromuscular blockade (TOF count= 1 - 3) on intraoperative surgical conditions assessed by the surgeon as a 5 points scale (Optimal= 5 points/ Good= 4 points / Adequate= 3 points / Poor = 2 points / Inadequate = 1 point) in patients undergoing laparosopy for benign gynecological pathologies.
The purpose of this study is to determine the minimum dose of ropivacaine 0.5%, required to produce pain relief without weakening the leg muscles.
This is an epidemiological multicenter, observational, prospective study, designed to determine the incidence of postoperative residual neuromuscular blockade - defined by a TOF (train-of-four) ratio < 0.9 - at PACU arrival. Subjects aged at least 18 years old (n=360) admitted for different types of elective surgical procedures requiring general anesthesia with neuromuscular blocking agents will be included.
Study Hypothesis The investigators approach to demonstrate noninferiority of analgesia provided by popliteal block in TKA surgery will be based on a hypothesis of absence of a clinically significant difference in pain visual analogue sores (VAS) between the analgesia provided by the popliteal block and that of the infragluteal sciatic block in TKA surgery patients.
This trial will evaluate the efficacy, safety, and pharmacokinetics of sugammadex for the reversal of both moderate and deep neuromuscular blockade (NMB) induced by either rocuronium or vecuronium in pediatric participants. The primary efficacy hypothesis of this investigation is that sugammadex is superior to neostigmine in reversing moderate NMB in pediatric participants as measured by time to recovery to a train-of-four (TOF) ratio of ≥0.9.
The purpose of this trial is to evaluate the safety and efficacy of Sugammadex when administered according to actual body weight (ABW) as compared to ideal body weight (IBW) for the reversal of both moderate and deep neuromuscular blockade (NMB) induced by either Rocuronium or Vecuronium in morbidly obese participants. The primary hypothesis of this investigation is that, compared to obese participants dosed based on IBW, obese participants receiving Sugammadex according to ABW will demonstrate a faster time to recovery to a Train Of Four (TOF) ratio of ≥0.9 (i.e. faster NMB reversal), pooled across NMB depth and type of neuromuscular blocking agent (NMBA; Rocuronium or Vecuronium) administered.
Pathophysiological changes influenced by multiple factors in critically ill patients, has a significant impact on pharmacokinetics (PK) and pharmacodynamics (PD) of cisatracurium. In order to understand better and find an appropriate dosing regimen, the purpose of this study is to investigate the PK and PD of a loading dose cisatracurium in critically ill patients. Cisatracurium, nondepolarizing neuromuscular blocking agents (NMBAs), are commonly used in intensive care units because of a lesser effect on hemodynamic parameters and a reduction in mortality rate in ARDS patients. Loading dose recommended in clinical practice guidelines for sustained neuromuscular blockade in the adult critically ill patient is 0.1-0.2 mg/kg. Then, maintenance dose of 1-3 mcg/kg/min is followed regarding indications, such as ARDS. However, this recommended loading dose might not be adequate in critically ill patients, the study in this specific population might be needed.
The aim of this study is to evaluate whether the use of Sugammadex for reversing the neuromuscular blocking effects of rocuronium during neurointerventional procedures can speed recovery of neuromuscular function. Half of participates will receive Neostigmine with glycopyrrolate, while the other half will receive Sugammadex.
The aim of this study is to evaluate the influence of depth of neuromuscular blockade during laparoscopic gastrectomy on postoperative pain in surgical patients allocated randomly to either deep or moderate neuromuscular blockade group with standard-pressure pneumoperitoneum of 13 mmHg.
