          Sugammadex has been a revolutionary reversal of neuromuscular blockade. It is known to be highly efficient. However, a change in the coagulation profile is one of the most dangerous potential complications which is a concern for both surgeon and anesthetist. Bleeding may cause hypovolemic shock, hematoma, and so on. To investigate the effects of sugammadex on coagulation profiles in patients with thyroidectomy, we compared patients that were treated with either sugammadex or neostigmine.

          Patients and Methods

          Eighty patients with thyroid neoplasms undergoing thyroidectomy were randomly allocated to sugammadex group (group S) or neostigmine group (group N). Induction of anesthesia was preformed using propofol, sufentanil, and rocuronium. Group S received sugammadex 2.0mg/kg after trachea intubation, similarly Group N received neostigmine 40 µg/kg, for reversal of rocuronium-induced neuromuscular blockade. The intraoperative coagulation profiles were monitored after the rocuronium injection (T0), 10 minutes after reversal (T1) and 30 minutes after reversal (T2) by testing activated partial thromboplastin time (APTT), prothrombin time (PT), fibrinogen (FIB), thrombin time (TT), and TEG-Haemonetics. Amount of bleeding was recorded during perioperative period.


          There was no significant difference in the thromboelastogram, APTT, PT, FIB, or TT measurements at each time point in Group N. The reaction time (R time) and kinetics time (K time) of Group S in T1 were significantly longer than the corresponding times at T0 and T2, and the R times were significantly longer than those in Group N at the same time points (P<0.05). Additionally, in Group S, the APTT was prolonged in T1 and returned to normal in T2.


          The result showed that sugammadex provided transient efficacy in prolonging the coagulation parameters, while neostigmine did not change the coagulation profile.

          Intraoperative neuromonitoring in thyroid surgery: Is the two-staged thyroidectomy justified?

          The aim of this study was to evaluate the diagnostic accuracy of intraoperative neuromonitoring (IONM) in predicting postoperative nerve function during thyroid surgery and its consequent ability to assist the surgeon in intraoperative decision making.

              Discovery, development, and clinical application of sugammadex sodium, a selective relaxant binding agent

              Neuromuscular blockade, induced by neuromuscular blocking agents, has allowed prescribed immobility, improved surgical exposure, optimal airway management conditions, and facilitated mechanical ventilation. However, termination of the effects of neuromuscular blocking agents has, until now, remained limited. A novel cyclodextrin encapsulation process offers improved termination of the paralytic effects of aminosteroidal non-depolarizing neuromuscular blocking agents. Sugammadex sodium is the first in a new class of drug called selective relaxant binding agents. Currently, in clinical trials, sugammadex, a modified gamma cyclodextrin, has shown consistent and rapid termination of neuromuscular blockade with few side effects. The pharmacology of cyclodextrins in general and sugammadex in particular, together with the results of current clinical research are reviewed. The ability of sugammadex to terminate the action of neuromuscular blocking agents by direct encapsulation is compared to the indirect competitive antagonism of their effects by cholinesterase inhibitors. Also discussed are the clinical implications that extend beyond fast, effective reversal, including numerous potential perioperative benefits.
