Filter by:The purpose of this study is to determine whether the leak pressure of the recently introduced laryngeal mask airway, Ambu AuraGain performs superior to the established laryngeal mask LMA Supreme in surgical patients undergoing general anesthesia. This leak pressure is the pressure at which a gas leaks around the airway, which is a key marker of efficacy and safety of its use; a higher leak pressure suggests a better seal between the artificial airway and patient's airway.
In prospective, safety-control study; children undergoing laparoscopic inguinal hernia repair using PIRS (Percutaneous Internal Ring Suturing) method will be randomly assigned into four groups. Gr 1: Endotracheal intubation and muscle relaxant, Gr 2: Endotracheal Intubation without muscle relaxant, Gr 3: Proseal Laryngeal Mask Airway without muscle relaxant, Gr 4: Proseal Laryngeal Mask Airway with subparalytic does muscle relaxant. Apart from standard monitorization, all patients' intragastric pressures will also be monitored. Patients' age at presentation, gender, time of surgery, time of anesthesia, intragastric pressure, intraabdominal pressure, intraoperative findings and complications will be noted and compared between groups.
This study will look at key performance indicators of 2 supraglottic airway devices in anaesthetised adults in a crossover manner.
Desflurane is known to be the most pungent of the currently used volatile anesthetics. The investigators tried to find out if desflurane increases the incidence of perioperative upper airway complications in infants and children undergoing general anesthesia using supraglottic airways compared to sevoflurane.
BACKGROUND AND OBJECTIVES The purpose of this study is to assess whether the loss of motor response to supraorbital pressure can be an alternative to that of jaw thrust to predict optimal condition for laryngeal mask airway (LMA) insertion in children. METHODOLOGY Fifty children (ASA I-II), aged 2 to 10 years, scheduled to receive general anesthesia that required LMA insertion were randomized to receive either supraorbital pressure (SOP) (n = 25) or jaw thrust (JT) (n = 25), after the loss of verbal response and body movements with a standard anesthetic. When motor response to the study intervention was absent, the LMA was inserted.
The investigators conduct this study to evaluate the clinical efficacy of size 1 and 1.5 supreme LMA compared to proseal LMA for infants weighing <10kg.
Objective of this prospective, randomized and controlled study is to compare the performances of recently-released size 1 I-gel and size 1 PLMA proven to be superior to classical LMA with prospective studies. In this study, primer endpoint was value of airway leak pressure and secondary insertion time, insertion success and conditions, initial airway quality, hemodynamic parameters, fiberoptic view and complications will be assessed.
The aim of this randomized prospective study is to compare two single-use laryngeal mask airways with a provision of a gastric drain tube allowing for evacuation of gastric contents, the i-gel and the LMA Supreme, in pediatric patients undergoing positive pressure ventilation. The investigators hypothesize that airway leak pressures with the i-gel will not be significantly different clinically (higher) when compared with the LMA Supreme.
The air-Q Self-Pressurizing Intubating Laryngeal Airway (aILA SP) is a modification of the air-Q Intubating Laryngeal Airway (aILA). Besides the i-gel, it is the only breathing tube that sits above the vocal cords that does not require inflation of a cuff with air. The purpose of this study is to compare the ability of the aILA-SP to maintain patency of a patient's airway during general anesthesia with that of the aILA and i-gel devices. As a measure of this ability, we hypothesized that the airway sealing pressures will be equal between the aILA-SP and aILA, but superior when comparing the aILA-SP to the i-gel (i-gel will be lower).
The aim of the current study is to compare the use of laryngeal mask airway (LMA) and endotracheal tube (ETT) in pediatric adenotonsillectomy. The primary objective is to assess the incidence of post-operative laryngospasm between the LMA and ETT. The investigators also sought to compare anesthetic, operative, and recovery times in the LMA and ETT groups. We hypothesized that the LMA would be a safe efficient alternative to the ETT.
