Filter by:A correct preoxygenation can be obtained after a 3min delay of calm ventilation through a tight mask thereafter mask is used to make the patient breathing before intubation. Most tight masks are actually sold but they have never been compared in studies. The aim of this study is to compare air leaks with standard facial mask and QuadraLite masks during preoxygenation and induction of anesthesia.
Comparison of conventional assessment of anesthetic depth by anesthesiologists (moderate, deep or light anesthesia) with EEG monitoring (Narcotrend® state/index). In case of mismatch statistical analysis for underlying factors are done.
Introduction Several attempts have been made to improve or facilitate epidural space detection beside conventional loss of resistant technique. Recently many sophisticated equipment's and techniques have been described which did not received widespread popularity. Objectives The Investigator describes and assesses the validity of using Pressure Gauge Manometer to confirm correct detection of lumber epidural space, in an inexpensive way. Methods Tuohy needle is introduced into intervertebral space at the level of L3-L4 up to the interspinous ligaments ( nearly 2cm mark on the needle).A3-way stopcock is connected to the hub of Tuohy needle with the in-line port of the stopcock attached to an air-filled 10 ml syringe. Using a 75 cm extension tube set and create a 30 mm Hg pressure gradient between manometer and the tip of epidural needle , the needle is advanced slowly using both hands while monitoring the manometer reading and is stopped when the pressure suddenly dropped ( the pressure usually drops by 5-10 mm Hg when the tip of the needle inters the epidural space ).
Effects of different doses of remifentanil on hemodynamic response to anesthesia induction in elderly patients ABSTRACT OBJECTİVE: The investigators compared the effects of three different doses of remifentanil infusion, which have been performed for the induction of anesthesia in elder patients, on cardiovascular response. PATIENTS AND METHODS: The present study was designed as a randomized, prospective and double-blind study. A total of 90 ASA I-II patients over the age of 65 years were enrolled and each group consisted of 30 subjects. The patients were randomly (by lot) assigned to receive one of the three doses of remifentanil infusion (0.1, 0.2 or 0.3 µg/kg/min) for two minutes. Subsequently, 0.5 mg/kg propofol was administered via IV route and, 0.5 mg/kg rocuronium was administered via IV route at the time eyelash reflex disappeared. Intubation was performed after two minutes. After recording baseline values of heart rate (HR), systolic arterial pressure (SBP), diastolic arterial pressure (DBP) and mean arterial pressure (MAP), these values were recorded at the 1st, 2nd, 3rd, 4th and 5th minutes of induction.
The aim of this randomized trial will be to evaluate the clinical performance of the I-gel, air- Q ILA compared with the LMA classic in pediatric patients undergoing peripheral surgery under general anesthesia.
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.
The objective of this trial is to determine whether an opioid-free general anesthetic (OFA) technique utilizing ketamine, dexmedetomidine, and lidocaine infusions can help reduce postoperative pain in opiate-dependent chronic pain patients (CPPs) undergoing spine surgery when compared with traditional opioid-containing techniques. It is expected that this OFA regimen will have a measurable reduction on postoperative opioid consumption and pain scores in CPPs.
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.
