Filter by:Background/aim: Investigators aimed to investigate the effect of D vitamin levels on Sugammadex and Neostigmine reverse durations in the study. Materials and methods: Eighty patients between 18 and 65 years, with ASA I-III status who were undergoing surgery under general anaesthesia were included the study. All patients were randomly divided into two groups with double blindness and 1.25 (OH) 2 vitamin D, 25 (OH) 2 vitamin D, and calcium levels were measured. At the end of the operation, 2 mg/kg of Sugammadex was administered to one group and Atropine + Neostigmine to the other group. The patients were also divided into two groups as to whether their vitamin D levels were ≥ 30 ng/mL or below. A train of four values was recorded after a hypnotic agent was given at the beginning and throughout the operation. The time to complete the disappearance of response to TOF stimulation was recorded as T0. End of the operation: When 2 responses to TOF stimulation were taken, the following times were recorded until the extubation phase by administering at least 2 mg/kg of Sugammadex or 0.05 mg/kg of Neostigmine 0.05 mg/kg of Atropine per kg of body weight. The time until the TOF value reached 50,70,90% and extubation were recorded.
Postoperative recovery after live donor nephrectomy (LDN) is largely determined by the consequences of postoperative pain and analgesia consumptions. The investigators' goal is to establish the relationship between the use of deep neuromuscular blockade (NMB) during laparoscopic donor nephrectomy (LDN) and the early quality of recovery. Therefore, the investigators designed a trial in which patients scheduled for living donor nephrectomy are randomized into a group with deep NMB or moderate NMB. The primary outcome measurement will be the Quality of Recovery-40 questionnaire (overall score) at 48 hours after extubation.
The investigators hypothesize that an anesthetic protocol maintaining deep neuromuscular block throughout the entire surgical procedure followed by sugammadex reversal, would suppress EMG activity and result in improved anesthetic stability by reducing the variability of the Bispectral Index of the EEG, and be beneficial by reducing the total doses of the anesthetic drugs propofol and remifentanil required to maintain an adequate level of anesthesia (BIS between 40 and 60).
The magnesium sulfate and lidocaine have been increasingly used alone or in combination during anesthesia procedure to meet various objectives, such as reduction of pain, use of smaller anesthetic doses and stabilization of hemodynamic parameters. These medicines are often used in combination with neuromuscular blocking agents, which may contribute to the occurrence of residual block in some patients after anesthetic procedures. It was estimated that only 1-3 % of patients with residual block developing clinically apparent events. In a small proportion of patients, the consequences of residual blockade are very serious and even lethal. It is estimated that 40 % of patients with muscle paralysis come to the post-anesthesia care unit (PACU). Considering that: (a) magnesium sulfate and lidocaine are showing an increasing number of applications in various areas of medicine, (b) these medications stand out for their properties analgesic, anti-inflammatory, anti-arrhythmic, neuroprotective and capable of reducing the demand of anesthetics and opioids, (c) magnesium sulfate as lidocaine has been important part of the therapeutic arsenal to control a large number of diseases (d) the patient surgical surgery or potentially have benefited in particular from its effects, (and) these drugs have been used routinely in many medical services as well as adjuvants in anesthesia, (f) previous studies have shown that magnesium sulfate is able to prolong the duration of neuromuscular blockade by different types of muscle relaxants, with controversies about its effect on latency (g) the effect of lidocaine on the action of muscle relaxants in current literature have shown great controversy and (h) do not exist in the literature studies involving both drugs; the investigators aimed to investigate the effects of magnesium sulphate infused alone or associated with lidocaine on the neuromuscular blockade promoted by cisatracurium, as well as evaluate its possible hemodynamic repercussions. For this purpose the SM was infused in bolus, prior to tracheal intubation and continuously during the maintenance of general anesthesia; the Lidocaine, when associated and the Isotonic Solution were used in the same way and timeline as SM. As secondary objectives it has been proposed to evaluate if the Lidocaine with Magnesium Sulfate would be able to interfere with the hemodynamic stability of the patients in the study.
Rationale: Endoscopic (thoraco-laparoscopic) esophageal surgery is a high risk procedure where the use of deep neuromuscular block (NMB) may increase field visibility and anaesthesia conditions. Under these conditions, boluses of muscle relaxants can be given on indication only OR by continuous infusion. We hypothesize that deep NMB by continuous infusion of rocuronium as compared to on demand bolus administration facilitates surgical and anesthesia conditions during thoraco-laparoscopic esophageal resection but higher doses of sugammadex are needed to reverse NMB at the end of surgery. Objective: Primary objective is to evaluate the use of deep muscle relaxation versus on indication only on surgical and anesthesia conditions in patients for endoscopic esophageal resection. Secondary objectives are to evaluate the (hypothetical) dose of sugammadex needed in both groups in an economical perspective and to compare the intra-operative cardiac and respiratory incidents and post-operative complication rate of both groups. Study design: a single-center randomized controlled double-blinded intervention study. Study population: All patients > 18 years to undergo a thoracolaparoscopic esophageal resection.I Intervention: Patients are randomized to receive either continuous infusion of rocuronium 0.6 mg/kg/hr (group 1) or continuous infusion of NaCl 0.9% 0.06 ml/kg/hr (group 2). On demand boluses of Rocuronium 0.3 mg/kg can be given in both groups. Main study parameters/endpoints: The primary outcome parameter of this study is the SRS during the abdominal phase of thoracolaparoscopic esophageal surgery. Secondary outcomes measured are SRS during the thoracic phase, the number of on demand boluses infused, the dose of Sugammadex needed in both groups to reach a TOF of > 90%, duration of surgery, a cost-analysis, the incidence of intra-operative cardiac and respiratory incidents and the ability of surgeons to estimate which neuromuscular blocking regime was given to the patient.
Adductor canal block will provide adequate analgesia to patients undergoing arthroscopic ACL reconstruction surgery, yet result in less motor blockade than a femoral block.
Sugammadex is a new reversal agent for neuromuscular blockers (curare). It encapsulates the curare molecule and terminates immediately its action. The recommended dose is 2 mg/kg for a slight neuromuscular block and 4 mg/kg for a profound neuromuscular block. Magnesium sulphate is frequently used in perioperative medicine and it is known to reinforce the neuromuscular block induced for instance by rocuronium. The researchers want to investigate, whether higher doses of sugammadex must be given to antagonize the neuromuscular block induced by rocuronium in patients who received magnesium sulphate.
This study is designed to compare recovery times after reversal of a residual neuromuscular block (TOF-ratio 0.5) with different doses of either neostigmine or sugammadex.
Lidocaine is a local anesthetic which is widely used in daily anesthesia and surgical practice. It has been shown that intravenous lidocaine given during an operation has analgesic properties. Finally intravenous lidocaine is inexpensive and easy to administer and safe if non-toxic doses are respected. It is likely that the use of lidocaine infusions during anesthesia might increase in the coming years. Neuromuscular blockers (curare like substances) are used in anesthesia to facilitate tracheal intubation and to achieve muscle relaxation and immobility during surgery. Rocuronium is one of the most widely used neuromuscular blocking agents. Local anesthetics, such as lidocaine, are known to potentiate the effect of neuromuscular blocking agents. In the study the investigators want to evaluate the effect of intravenous lidocaine during the operation on the time course of the rocuronium-induced neuromuscular block. A secondary aim is to evaluate intubation conditions (lidocaine has been shown also to improve intubation conditions) and safety.
