13 Clinical Trials for Various Conditions
The investigators propose a single-center,assessor-Blinded, parallel group randomized trial to compare the efficacy of reversal of rocuronium induced neuromuscular blockade by sugammadex versus neostigmine in patients undergoing Endoscopic retrograde cholangiopancreatography at Cleveland Clinic Main Campus.
This study is intended to be a single-site, prospective, randomized, controlled study that intends to enroll a total of 230 patients undergoing laparoscopic cholecystectomy at Parkland Hospital. Patients will be randomized to receive either neostigmine or sugammadex for reversal of rocuronium-induced 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. To account for protocol deviations and patient dropout, up to 250 randomization envelopes will be made and enrollment will continue until there are 230 completed enrollments.
The investigators propose a randomized trial comparing sugammadex and neostigmine for the reversal of neuromuscular blocks induced by rocuronium or vecuronium in adults having general anesthesia with muscular block for noncardiac surgery.
The study is designed to determine whether patients who receive sugammadex immediately after tracheal extubation will exhibit a decrease in the incidence of postoperative residual paralysis and an associated decrease in the incidence of postoperative respiratory depression.
Protective airway reflexes may be impaired in the postoperative period, creating the potential for aspiration of gastric contents, even after a patient exhibits appropriate response to command. Because assessment of airway reflex recovery is not possible in an intubated patient, the clinician must make an empiric decision as to when a patient is safe to extubate, and choose a combination of techniques least likely to result in pharyngeal impairment. Adequacy of reversal of neuromuscular block by cholinesterase inhibitors (e.g., neostigmine) is unpredictable, especially in the presence of profound paralysis, and tactile assessment of train-of four and sustained tetanus has shown poor correlation with objective assessments. Protective airway reflexes may also be impaired during early recovery by the anesthetics themselves, even when muscle relaxant has been avoided. In the absence of muscle relaxant the investigators previously demonstrated that patients receiving an anesthetic with higher tissue solubility, sevoflurane showed significantly greater impairment of swallowing up to 14 minutes after response to command compared to patients receiving an anesthetic with lower tissue solubility, desflurane. Therefore, we ask whether the combination of the more soluble anesthetic and the presence of neuromuscular block antagonized by neostigmine may create a multiplicative effect that might further prolong pharyngeal recovery. We plan to randomly assign 100 patients scheduled to undergo surgery with general anesthesia to a standardized anesthetic that includes 1) sevoflurane, rocuronium with 70 µg/kg neostigmine + 14 µg/kg glycopyrrolate antagonism (group S); or 2) desflurane, rocuronium with 70 µg/kg neostigmine + 14 µg/kg glycopyrrolate antagonism (group D). Airway reflex recovery will be judged as adequate by the patient's ability to swallow 20 mL of water without coughing or drooling 5, 10, 15, 20, 30 and 60 minutes after response to command. Anesthetic (sevoflurane or desflurane) will be discontinued after administration of reversal agent and recovery to TOF (train-of-four) ratio of 0.7.
This study will compare patient recovery measures after reversal of neuromuscular blockade with neostigmine or sugammadex after surgery. Measures include pulmonary function, muscle strength, time to extubation and quality of recovery in the post anesthesia care unit.
Patients undergoing surgery often receive paralytic agents (or neuromuscular blocking agents (NMBAs)) to facilitate the procedure. At the end of surgery, the effects NMBAs are reversed with a drug called neostigmine. The use of neostigmine significantly reduces the risk that a patient will be left with muscle weakness in the recovery room. Many anesthesiologists routinely use neostigmine because postoperative muscle weakness may lead to adverse events after surgery. Other anesthesiologists do not routinely administer neostigmine in the operating room because of concerns about potential side effects. Surprisingly, some investigators have reported that neostigmine-induced muscle weakness may occur if the drug is given when the effects of the NMBAs have completely worn off. In contrast, other investigators have not observed this side effect when neostigmine was given at the end of surgery. The aim of this study is to determine whether neostigmine use is associated with muscle weakness when it is given at the time of nearly complete recovery from NMBAs. Muscle strength will be measured using a sensitive monitor (TOF-Watch-SX) and through an examination of the patient for evidence of muscle weakness. Patients will also be evaluated how they recover from anesthesia and surgery.
The control of postoperative pain has become a major issue in surgery awareness and it is considered an important measurement of patient satisfaction. Improvements in pain relief, including stopping pain before it starts (i.e. preemptive treatment) is of great benefit to the surgical patient. When pain is aggressively addressed, patients respond by recovering faster. The use of opioids remains the mainstay to minimize postoperative pain. Lately, long acting local anesthetic wound infiltration has been widely recognized as a useful adjunct to multimodal postoperative pain management. On that basis, a system that delivers a continuous local anesthetic to the surgical wound was developed, and better pain control has been achieved after several surgical procedures. In patients undergoing abdominal procedures, such as colon resection, adequate pain control remains an issue. It is known that innervation to the antero-lateral abdomen is provided by sensory nerves T7-L1, ilioinguinal and iliohypogastric nerves, which travel through the transverse abdominis muscle plane (TAP). Local anesthetic block of these nerves has been described and has shown to be effective for immediate postoperative pain control. Recently, the use of the On-Q pain relief system with catheters placed within the TAP has been evaluated. Published results have shown significant improvement of pain control (Forastiere). The idea of placing the pain catheters at the TAP plane seems to be more coherent with the anatomical distribution of the sensory nerves trunks. Due to the lack of prospective trials investigating the effectiveness of a continuous wound infusion with local anesthetics after general surgery procedures the investigators sought to determine the efficacy of this technique after laparoscopic colon resection procedures.
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 researchers are investigating if the Self-Supporting Nasopharyngeal Airway (ssNPA) device can be used in the treatment of obstructive sleep apnea in children with Hypotonic Upper Airway Obstruction (HUAO).
This is a two period cross-over study randomizing patients undergoing laparoscopic surgery into 2 different groups: group 1 in which patients receive "deep neuromuscular blockade" in the beginning portion of their laparoscopic surgery followed by a period of "moderate blockade" and, group 2 in which patients receive "moderate neuromuscular blockade" in the beginning portion of their laparoscopic surgery followed by a period of "deep blockade". The deep neuromuscular block is defined as post tetanic count of 1 to 2 and the moderate neuromuscular block is defined as 1-2 twitches. In all patients, sugammadex is used to reverse the block at the end of surgery in order to obtain optimal extubating conditions.
The study will investigate the difference in success rate between popliteal peripheral nerve catheters placed at 1 centimeter compared to 5 centimeters past the tip of a Tuohy needle.
