Filter by:60 patients, in three group of 20 patients each, scheduled for surgery needing general anesthesia will be researched. Group A: tracheal intubation of single lumen tube using laryngoscope. Group B: single lumen tube using lightwand. Group C: double lumen endobronchial cath. During general anesthesia, the spectral power of heart rate variability at three periods: (1) preoperation baseline (2) pre-intubation and (3) post-intubation will be calculated and compared to investigate the autonomic stimulation effect of different tracheal intubation methods.
The GlideScope video laryngoscope (Verathon) is an intubating device that uses a high-resolution camera embedded into a plastic laryngoscope blade. An LED provides illumination. The GlideScope often provides a good laryngoscopic view, but passing the endotracheal tube (ETT) through the vocal cords is sometimes difficult. Because of the 60 degree anterior curvature of the GlideScope's blade, ETT's must have stylets inserted so that the ETT distal tip can be positioned anteriorly. Various authors have recommended different angles of the ETT to optimally place it into the trachea. Previous study demonstrated that 90 degree sharp bend was both faster and subjectively easier in a heterogeneous group of intubators. With the introduction of a rigid GlideScope Specific Stylet by the manufacturer, the question arises as to the the best configuration of stylet for the ETT. Therefore, this prospective, randomized, single-blinded trial is proposed. The null hypothesis is that there will be no difference between the GlideScope Specific Stylet and the standard malleable stylet.
This study is intended to validate the use of neck auscultation with an electronic stethoscope during intubation to confirm tracheal tube placement. It is hypothesized that the ability to confirm correct tube placement with this technique will be similar to that of the end-tidal CO2 monitor, the current gold-standard device for confirming tracheal intubation.
The objective of this study is to determine the efficacy and safety of Dexmedetomidine, a selective alpha-2 adrenoceptor agonist, which has recently gained increased popularity for ICU and intraoperative sedation as a sedative during awake fiberoptic intubation, as compared to Remifentanil. The hypothesis is that Dexmedetomidine will provide at least equal if not better conditions (sedation and analgesia) required for awake fiberoptic intubation (Ramsay Sedation Scale 3) with less respiratory and cardiovascular adverse effects, as well as less recall than Remifentanil.
The purpose of this study is to determine if the Ambu Laryngeal Mask can be used as an intubation conduit for endotracheal intubation.
The purpose of this study is to determine if the Video Laryngoscope (VL) is a useful instrument in patients at risk for difficult intubation. We will compare this device to the traditional Macintosh Laryngoscope.
