Abstract
We hypothesized that neostigmine administered after recovery of the train-of-four (TOF) ratio impairs upper airway integrity and genioglossus muscle function.
We measured, in 10 healthy male volunteers, epiglottic and nasal mask pressures, genioglossus electromyogram, air flow, respiratory timing, a...

Abstract
None experienced airway obstruction or arterial oxygen desaturation, even at normalized TOF ratio less than 0.4. Functional residual capacity remained unchanged whereas vital capacity decreased linearly with decreasing TOF ratio. The ability to protrude the tongue was preserved at all times. The abi...

Abstract
40 CMAPs from 5LVB and 60 CMAPs from 6LVB patients were compared with each other within L3 to S levels. First, there was no difference between groups in the pattern of radicular pain and myotomal innervation at the level L3/4 and L4/5 (p=0.39-1.0). Second, the nerve root stimulated at the L5/6 level...

Abstract
L-cysteine adduction occurs at different rates by design in olefinic isoquinolinium diester neuromuscular blockers, yielding corresponding durations of action. Antagonism by exogenous L-cysteine is superior to anticholinesterases, inducing inactivation of the active molecules to restore function rap...

Abstract
The aim of the second part of this review is to examine optimal neuromuscular management strategies that can be used by clinicians to reduce the risk of residual paralysis in the early postoperative period. Current evidence has demonstrated that frequently used clinical tests of neuromuscular functi...

Abstract
We summarize the clinical implications of residual neuromuscular block. Data suggest that residual neuromuscular block is a common complication in the postanesthesia care unit, with approximately 40% of patients exhibiting a train-of-four ratio <0.9. Volunteer studies have demonstrated that small de...

Abstract
Emergency physicians perform tracheal intubation and initiate mechanical ventilation for critically ill patients on a daily basis. With the current national challenges of intensive care unit bed availability, intubated patients now often remain in the emergency department (ED) for exceedingly long pe...

Abstract
We administered sugammadex to a patient with myasthenia gravis to reverse a rocuronium-induced profound NMB. NMBDs predispose such patients to severe postoperative residual paralysis and respiratory complications. Sugammadex binds steroidal NMBDs and, therefore reverses a rocuronium or vecuronium-in...

Abstract
Many recent studies have underlined the importance of quantitative neuromuscular monitoring and the high incidence of residual block in clinical practice in spite of the use of nondepolarizing neuromuscular blockers of intermediate duration. Neuromuscular monitoring facilitates the tailoring of the...

Abstract
We have achieved a return to spontaneous circulation in a growing proportion of patients with cardiac arrest. Nevertheless, most of these patients die in the first few days after admission to the intensive care unit (ICU), and this situation has not improved over the years. Mortality in these patien...

Abstract
The review covers the history of neuromuscular block reversal. It states that indications for decurarization have been changed due to the extremely high rate of residual curarization even after the use of average-acting myorelaxants. The paper provides the pharmacological characteristics of sugammad...

Abstract
We conducted a prospective observational study to assess the incidence of residual neuromuscular blockade (RNMB) in a post-anaesthetic care unit (PACU) of a tertiary hospital. The subjects were 102 patients undergoing general anaesthesia with neuromuscular blockade (NMB). The procedural anaesthetist...

Abstract
When given at a TOF ratio of either 0.4 or 0.6, time to 0.9 and 1.0 TOF ratio was significantly shorter with any dose of neostigmine than without. The probability of successful reversal after 20 microg/kg neostigmine was 100% when a TOF ratio of 0.9 was the target; for a TOF ratio of 1.0, the probab...

There were no significant differences between groups in terms of QTc (Fridericia) interval. Three serious adverse events, one in each treatment group, considered to be possibly drug-related according to the investigator, were cases of mild QTc (Bazett) interval prolongation.

Abstract
Neostigmine, the currently used agent for reversal of neuromuscular block, has several drawbacks, such as a slow onset of peak effect, inability to reverse deep block and the occurrence of widespread muscarinic effects. Sugammadex is a new class of reversal agent that acts by encapsulating the molec...

Abstract
Sugammadex is a cyclodextrin molecule that encapsulates and inactivates rocuronium and vecuronium. As a result, any degree of neuromuscular block produced by rocuronium or vecuronium can be rapidly and completely reversed without autonomic effects. Because sugammadex is optimised for reversing rocur...

Abstract
The availability of sugammadex allows greater flexibility in the use of rocuronium and vecuronium during anaesthesia and surgery. The neuromuscular block induced by both drugs can be reversed from both superficial and deep levels of block by adjusting the dose of sugammadex. The dose of sugammadex f...

There is now mounting evidence that even small degrees of postoperative residual neuromuscular block increases the incidence of adverse respiratory events in the Post Anaesthesia Care Unit and may increase longer-term morbidity as well.

No drugs in anaesthesia are more problematic than suxamethonium. Yet, no drugs have survived as suxamethonium does in spite of crisis after crisis, and attempt after attempt at its replacement.

Neuromuscular blocking drugs are designed to bind to the nicotinic receptor at the neuromuscular junction. However, they also interact with other acetylcholine receptors in the body. Binding to these receptors causes adverse effects that vary with the specificity for the cholinergic receptor in ques...

We concluded that the 10 cmH2O of PEEP attenuates the effects of PnP in respiratory mechanics, lowering R(RS), E(P), and E(RS). These effects may be useful in the ventilatory approach for patients experiencing a non-physiological increase in IAP owing to PnP in laparoscopic procedures....

Depression ofT1/T0 was enhanced under sevoflurane compared to TIVA. ED50 and ED95 values of both drugs were significantly lower under sevoflurane more than TIVA. Recovery index 25-75% and time to a TOF ration of 0.70 were prolonged significantly by sevoflurane compared to TIVA. Hemodynamically, rocu...

Administration of rocuronium at dose of 0.25 to 0.5 mg/kg IM is a safe and effective adjunct to clinical proceedings or pre-anesthetics in P. expansa. Because rocuronium does not provide any analgesic or sedative effects, the duration of neuromuscular blockade without anesthesia should be minimized...
