Filter by:In surgery under general anesthesia due to nasal bone fracture, laryngeal mask airway or tracheal intubation has been used. However, it has not been investigated that the difference of recovery profiles according to use of laryngeal mask airway or tracheal intubation in nasal bone fracture surgery. The aim of study is to evaluate the efficacy of the laryngeal mask airway regarding recovery profiles and airway complications, compared to tracheal intubation.
Airo-Q Self Pressurized airway device with Blocker will be compared with Proseal LMA in anesthetized adult female patients undergoing elective surgeries to discuss the influence of different head and neck positions on the performance of both devices. Oropharyngeal leak pressure, peak inspiratory pressure, ventilation score and fiber-optic view will be assessed in neutral, flexion, extension and lateral positions in both groups.
Compare the accuracy of two methods of ultrasound and air leakage test in positioning laryngeal mask. Validate the relationship between ultrasound scores, air leak levels, and bronchoscopic classification in positioning laryngeal mask
This study will be conducted to evaluate effects of different modes of ventilation on pediatric cataract surgery aiming to a peri-operative stable anesthesia, better surgical satisfaction and post operative recovery. It is hypothesized that controlled ventilation without muscle relaxation will be advantageous to other modes in providing adequate surgical satisfaction with considerable depth of anesthesia and better recovery profile.
The purpose of this study is to compare the first attempt success rate of laryngeal mask airway insertion according to the degree of head elevation.
Prospective, controlled, randomized study to compare Ambu AuraGain with Intersurgical i-Gel mask during mechanical ventilation in patients undergoing laparoscopic cholecystectomy. The investigators hypothesise that when comparing the Ambu® AuraGainTM with Intersurgical i-GelTM mask, the Ambu® AuraGainTM would exhibit a higher oropharyngeal leak pressure (OLP) during mechanical ventilation in patients undergoing laparoscopic cholecystectomy. The main goal is to compare the Ambu AuraGain with the i-Gel in terms of safety and efficacy during mechanical ventilation in critical phase of the pneumoperitoneum in lateral decubitus and reverse trendelemburg position. Secondary objectives are comparing insertion time, number of attempts, ventilatory airway peak pressure, time and success rates for gastric tube insertion and the incidence of side effects.
Laryngeal Mask Airway (LMA) is widely used in pediatric surgical patients. The manufacturer recommends the size of LMA to be used in children should be based on actual body weight but this method has several limitations. To overcome these concerns, various alternatives have been tried by different researchers, one of them is external ear size for LMA size selection. Investigators therefore would like to know whether the external ear size based method can be used for LMA size selection in pediatric surgical patients in Pakistan.
The ProSeal laryngeal mask airway (ProSeal LMA; Intavent Orthofix, Maidenhead, UK) is a device with a double cuff to improve the seal and a drain tube to help prevent aspiration and gastric insufflation, facilitate passage of a gastric tube, and provide information about malposition. The manufacturer recommends inserting the ProSealTM LMA using digital manipulation or with an introducer tool, but both these techniques have lower success rates than the classic LMA. This prospective study that will investigated the usefulness of the C-MAC videolaryngoscopy for inserting a PLMA in anesthetized non-paralyzed patients and compared it with the index finger.
This prospective, randomized, comparative study is intended to enroll a total of 148 patients with a BMI 30-49.9 kg/m2 undergoing surgery at Parkland Hospital. The efficacy and performance of a second-generation LMA will be compared to endotracheal intubation. A standardized anesthetic protocol that is usual and customary for the type of operation the patient is having will be provided to the anesthesia teams of enrolled subjects. The remainder of the anesthetic care of the subject will not deviate from the standard of care.
The use of supraglottic airway devices with a gastric emptying tube in gynecological laparoscopic surgeries is growing. In addition to their ease of placement, they have low airway morbidity along with sufficient airway pressure in the Trendelenburg position and so they have been determined as an alternative to the endotracheal tube.
