Filter by:Upper airway obstruction commonly occurs after induction of general anesthesia. The aim of this study is to determine if head rotation improves the efficiency of mask ventilation of anesthetized apneic adults.
Anecdotal data suggest that the buffered form of the local anesthetic is more potent at equal dosages, and a lower dosage of the buffered drug might be used with an effect equal to higher dosage not buffered. Clinical data are needed to confirm these anecdotal data. No published data exist comparing buffered local anesthetics at lower drug concentrations to current dosages commonly used in dental and oral surgical procedures
The present study is designed to validate an multimodal indicator of anesthetic depth (Schneider G et al. 2014, Anesthesiology 120, 819-28). The indicator previously developed shall now be tested on an independent set of data. The investigators will include 250 patients undergoing general anesthesia in 3 German tertiary care centers. The design is strictly observational - the anesthetic regime is at the discretion of the clinician and will not be influenced.
Regional anesthesia in orbit can reduce ocular blood flow, increase in intraocular pressure (IOP) or the pharmacological action of local anesthetics. This study was conduced to evaluate the effects of clonidine added to lidocaine in IOP, ocular perfusion pressure (PPO) and ocular pulse amplitude (OPA) in patients undergoing cataract surgery under sub-Tenon's and peribulbar anesthesia.
Participant is being asked to take part in this study because participant is going to have surgery that requires general anesthesia (in which participant is unconscious for the procedure). During surgery, anesthesiologists often place a supraglottic airway device (SGAD). An SGAD is a device that helps participant breathe and may help the anesthesiologist put a breathing tube in participant's airway while participant is asleep during surgery. There are many different kinds of SGADs that are readily available for use by anesthesiologists during surgery. The SGADs that are being studied are the Ambu Auragain and the Teleflex LMA Protector. The goal of this clinical research study is to compare the effectiveness of both devices. This is an investigational study. Both of the SGADs that are being used on this study are FDA approved and are frequently used for the surgery that participant is going to have. It is investigational to compare the 2 devices. Up to 50 participants will be enrolled in this study. All will take part at MD Anderson.
The investigators aim to investigate operating conditions, postoperative recovery and overall satisfaction of surgeons between deep neuromuscular blockade (NMB) group and restricted NMB group during spinal surgery under general anesthesia. The investigators hypothesize that this study can present good surgical conditions, postoperative recovery outcomes and overall satisfaction of surgeons in deep NMB group, thereby proving the advantages of deep NMB as well as flaws of restricted NMB in spine surgeries.
Rapid sequence induction (RSI) is a well-known procedure to maintain a safe and rapid airway in patients especially at risk of aspiration. Propofol and rocuronium are generally used agents for RSI. However, the difficult airway scenarios are always valid for these patients, even without predictive signs of difficult airway. Therefore, it is important to decrease the rocuronium dose used in RSI to achieve a rapid recovery of a neuromuscular conduction with the aid of a reversal agent in case of difficult airway. The short acting opioids such as remifentanil may be helpful to reduce the dose of rocuronium in RSI.

Comparison of the preoxygenation efficacy of tidal volume breathing using three different preoxygenation techniques which are available to providers in the prehospital environment.
In this prospective study, investigators plan to evaluate the outcome of general anesthesia in the context of patients with a positive cocaine urine test. Patients with a positive urine cocaine test who do not appear acutely toxic and have normal vital signs may not have an increased rate of perioperative complications during elective surgery compared to similar patients with negative urine cocaine screening tests. Patients who are chronic cocaine users may have a higher anesthetic requirement.
