Filter by:This study is a multicenter, randomized, controlled, double-blinded, and parallel design study. A total of 96 patients were decided to be recruited considering a 10% dropout rate. Patients are randomized to receive a deep block or a moderate block. The randomization numbers are generated using a computer-generated randomization code (1) and are sealed in the opaque envelope until they are handed over to the anesthesiologist in charge of anesthesia management after the induction of anesthesia. Patients, surgeons reporting the scale of surgical status, and another researcher analysing the cytokines levels are blinded to the patient group. Patients aged 18-65 yr, ASA 1 or 2, and are scheduled for elective laparoscopic gastrectomy are included. Patients with severe respiratory or cardiac disease, hepatic or renal function impairment, on medications affecting neuromuscular function, and with known allergy to the drugs to be used are excluded.
Use of neuromuscular blockade (NMB) may improve the surgical work space in patients scheduled for laparoscopic surgical cases (e.g. hysterectomy, ovarian cystectomy, myomectomy). Clinical studies investigating this question often use a numerical or verbal rating scale for subjective evaluation of the surgical workspace. However, no good subjective rating scale have been developed or validated. Neither have possible inter-individual differences in use of such subjective scales been described. Purpose: The aim of this study is to validate different subjective rating scales to determine which scale is most useful among surgeons.
This study is designed to determine the effective-doses ED-50 and ED-95 (the doses required for a 50% and 95% twitch inhibition, respectively) of the non-depolarizing muscle relaxant rocuronium after single-shot or steady-state propofol anesthesia in a clinical setting.
To investigate if deep neuromuscular blockade improves intraabdominal volume compared to no neuromuscular blockade in patients scheduled for gynecologic laparoscopic surgery with pneumoperitoneum 12 mmHg. Hypothesis: Deep neuromuscular blockade improves intraabdominal space (the distance from promontorium to skin surface, cm) compared to no neuromuscular blockade.
The study examines the clinical application of TOF (train of four test) used by anesthesiologists and neurophysiologists during instrumented spine procedures, as well as certain associated parameters. 'Train of four' test is a test routinely used during the surgery, which is performed by stimulation of peripheral nerve with purpose to determine the degree of muscle relaxation by interpretation of muscle response. During spine surgery, it is helpful for the surgeon to have a patient's muscles as relaxed as possible with the least amount of tone, especially when exposing. Anesthesiologists achieve this level of relaxation by giving a neuromuscular blocking agent. If medication given to do this has not fully left their system by the time the surgeon needs to start putting in the screws and rods, then the intraoperative monitoring can not be adequately performed. If the muscles are too relaxed, then free run EMG and screw stimulation, two monitoring methods used, will not be analyzed correctly and the surgery may be adversely affected. This study compares the results of the 'train of four' test performed by neurophysiologists and anesthesiologists. Additionally, it looks at the differences, if any, in comparing stimulation of the foot nerve (tibial n.) or hand nerve (ulnar n.) Performing the TOF (train of four test) in the lower extremity can be relevant for many reasons. Train of four tests can show the presence of four twitches in the arms but the legs may not fully recovered from muscle relaxant given by anesthesia. Also, train of four test which uses subjective method of interpretation by anesthesiologists may present different results compared than objective quantitative method of train of four test interpretation. Ultimately, the goal of this study is to show the importance of 'TOF' testing in ensuring that any identifiable preventable intraoperative surgical complication is appropriately identified.
Should the dose of sugammadex in morbid obese patients be calculated on the real body weight or the ideal body weight? To study the pharmacodynamics of sugammadex in morbidly obese patients by comparing 1 mg/kg IBW versus 1 mg/kg TBW versus placebo.
The aim of this study is to determine the recovery time of moderate neuromuscular blockade with sugammadex in adults pretreated with magnesium sulfate.
A new ultrasound-guided "subgluteal space" approach to sciatic nerve block that has been recently described obviates the need to identify the sciatic nerve. The investigators hypothesize that the use of an ultrasound-guided subgluteal space injection to perform sciatic nerve block will increase the proportion of patients experiencing complete sensory block in both terminal branches of the Sciatic nerve in comparison to the same proportion in those who receive the block via ultrasound-guided infragluteal approach with circumferential injection in patients scheduled for unilateral TKA(total knee arthroplasty) surgeries.
The purpose of this clinical trial is to prove that the administration of sugammadex at a dose of 4 mg/kg for counteracting deep blockage [without train-of-four (TOF) ratio response and post-tetanic count (PTC) < of 2 induced and maintained with Rocuronium in pediatric patients for short-term elective surgery.
This study is designed to investigate the frequency of Residual Neuromuscular Blockade (RNMB) in the pediatric population.
