Summary

Liver cirrhosis is a progressive disease characterized by loss of functional hepatocytes that substantially affects drug pharmacokinetics. Rocuronium onset time is longer and recovery time from it is prolonged in cirrhotic patients than in those with normal liver function. This randomized controlled study is designed to compare the pharmacodynamic profiles of sugammadex and neostigmine when used for the antagonism of moderate degree of rocuronium-induced neuromuscular block in cirrhotic patients undergoing liver resection and in patients with preoperative normal liver functions undergoing liver resection.

Detailed description: Liver resection is a lengthy operation that has major effects on patient hemodynamics and perioperative liver functions. These effects are more obvious in patients with liver cirrhosis. Liver cirrhosis is a progressive disease characterized by loss of functional hepatocytes that substantially affects drug pharmacokinetics. Rocuronium is an intermediate acting steroidal non-depolarizing neuromuscular blocker that is mostly metabolized by the liver. Its onset time is longer in cirrhotic patients than in those with normal liver function. This can be explained by an increase in the volume in which it initially distributes. Although elimination kinetics are unchanged in patients with cirrhosis, Rocuronium recovery time is prolonged in cirrhotic patients. To speed up the process of antagonism of residual neuromuscular blockade, inhibitors of acetyl cholinesterases such as Neostigmine are usually administered only when there is evidence of spontaneous recovery of neuromuscular function. Too early administration of Neostigmine is not effective and may produce serious side-effects from accumulation of Acetylcholine in other organs, especially the brain and heart. Sugammadex, a modified γ-cyclodextrin, is the first selective relaxant binding agent. It forms very tight, stable complexes in a 1: 1 ratio with Rocuronium. The inactive Sugammadex-Rocuronium complex undergoes renal elimination. Sugammadex has no effect on acetyl cholinesterases or on any receptor system in the body, eliminating the need for anticholinergic drugs. Sugammadex can antagonize any level of neuromuscular blockade, including the profound blockade induced by Rocuronium. The use of Sugammadex in different patient populations including end-stage renal failure is associated with consistent, complete and rapid recovery of neuromuscular functions. It is of clinical relevance to note that in the presence of Sugammadex, the hepatic biotransformation and final clearance of Rocuronium via biliary excretion is changed to a completely different (liver-independent) renal pathway. A recent report described the successful use of Sugammadex to antagonize prolonged deep rocuronium-induced neuromuscular block in patients with normal liver functions undergoing liver resection. Furthermore, the successful use of Sugammadex to antagonize Rocuronium neuromuscular block was also reported in a case series of three patients with liver dysfunction. To the best of our knowledge, there are no controlled randomized studies evaluating the use of Sugammadex to antagonize residual Rocuronium-induced neuromuscular blockade in patients with liver cirrhosis undergoing open surgical liver resection. This randomized controlled study is designed to compare the pharmacodynamic profiles of Sugammadex and Neostigmine when used for the antagonism of moderate degree of Rocuronium-induced neuromuscular block in cirrhotic patients undergoing liver resection and in patients with preoperative normal liver functions undergoing liver resection.
