Filter by:This study aims to investigate whether the use of a video LMA device (SacoVLM™) will facilitate successful supraglottic airway device (SAD) insertion compared to the use of a conventional 2nd generation SAD (Ambu®Auragain™) in elderly patients. This study is a randomized trail with a 50% probability of being assigned to either group. Randomization will be done by an anesthesiologist not involved in anesthesia or postoperative outcome assessment. Patients and the investigator in charge of postoperative outcomes assessment will be blinded to group allocation.
Tracheal intubation is considered the gold standard for protecting the airway. As the supraglottic airway devices (SADs) could be inserted without laryngoscopy, so that SADs with different designs and safety issues could be used to manage difficult airways in anesthesia and emergency medicine with continuous patient oxygenation &ventilation, less hemodynamic stress response and less postoperative complications. Many health care providers do not have the requisite knowledge and enough practice to perform safe and quick intubation. For these providers, SADs can be a valid alterative especially in untrained personnel, or when tracheal intubation is impossibe. Both devices are with a cuff modified to improve the seal around the glottis and a drainage tube to provide a bypass channel for regurgitated gastric contents, prevent gastric insufflation, and allow the passage of a gastric tube. These features are designed to improve the safety of the mask and broaden its scope, especially when used with positive pressure ventilation. The AuraGain is Ambu ꞌs 3rd generation disposable laryngeal mask, satisfying 3 fundamental airway management needs by integrating gastric access channel for managing gastric content and intubation capability using standard ET-tubes in an anatomically curved single-use device that facilitates rapid establishment of a safe airway through integrated bite absorption area that could prevent airway occlusion. Other characters include pilot balloon that identifies mask size and provides tactile indication of degree of inflation, navigation marks for guiding flexible scope and is made of phthalate-free material. Its thin and soft cuff is designed to deliver high seal pressure up to 40 cmH2O. It was presented in the clinical market in sizes 3, 4, 5 and 6 (according to the body weight; size 3: 30-50 kg, size 4: 50-70 kg, size 5: 70-100 kg, and size 6: >100 kg) that can accept tracheal tube in sizes ranging from 6.5 up to 7.5 and 8mm inner diameter respectively with maximum suction catheter size of 16 Fr. The LarysealTM Pro is the new generation mask for safe and effective airway management, as it could reduce the risk of aspiration by the integrated suction catheter port to allow effective removal of fluids and gastric contents. So that, it could be a promising airway device as its symmetrical cuff and tube contoured to match the oropharyngeal anatomy for quick and easy first time insertion success. It could be applied in both routine and advanced airway management for patients with a higher risk of a difficult airway, unexpected intubation difficulties, beside to airway control during anesthesia. It was presented in the clinical market in sizes 3, 4 and 5 (according to the body weight; size 3: 30-50Kg, size 4: 50-70 Kg, and size 5:70-100Kg) that can accept larger tracheal tube up to 7.5 and 8mm inner diameter respectively with maximum suction catheter size of 16 Fr. The Laryseal pro could provide a rapid and secure airway management and improve patient safety with gastric access reducing the risk of pulmonary aspiration, in addition to speeding up the ETT tube placement if needed with a unique guide system, beside to integrated fenestrated flap that protects from blockage with minimal increase in flow resistance. All these features of laryseal pro allow quick easy first time insertion success. After approval of the Local Ethical Committee and obtaining an informed written consent from every patient, then patients will be categorized randomly into two equal groups using the computer allocation software to be put into opaque closed-envelopes: GL (n=27): Laryseal TM Pro. GA (n=27): Ambu Aura Gain.
This study is designed to observe the occurrence of failure or difficulty during placement of supraglottic airway devices (SGAs) and its associated risk factors in pediatric patients. Despite wide use in pediatric practice, not much is known related to problems during SGA insertion unlike adults. The main information regarding pediatric SGA comes from either small comparative studies or retrospective studies reporting increased risk of failure. Thus the main aim of this prospective, multicentric, observational study is to determine the incidence of "difficult" or "failed" SGA placement in children and clarify the possible risk factors for difficulty.
- In pediatric surgery and emergencies, LMA represents a useful airway management device for routine and difficult airway management. - Inserting an improper LMA size may result in malposition, displacement within the hypopharynx, and failed ventilation that needs repositioning. - Selection of the size of LMA represents a major challenge for anesthesiologists, especially in children. - The ultrasonographic measured hyomental distance showed a correlation with the length of the pharyngeal cavity. - Optimization of the size of the inserted LMA can be confirmed either clinically, ultrasonographic or through the fiberoptic laryngoscope. - The ultrasonographic measured hyomental distance confirmed the optimization of LMA with results comparable to that of the clinical methods and better than those of the fiberoptic laryngoscope.
the aim of our study is to investigate if stimulation of the P6, LI4 and LI11 acupuncture points via laser acupuncture prevents sore throat caused by the classic laryngeal mask.
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
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 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.
Currently, the main method for selecting an i-gel® size is based on the body weight recommendation (30-60 kg for size 3 and 50-90 kg for size 4) according to the manufacturer's recommendation. However, there is an overlapping in size selection in people weighing between 50 and 60 kilograms. Laryngeal mask airways are widely used for breast surgery, and this patient cohort is often weighed between 50-60 kilograms in National Taiwan University Hospital. Therefore, in this randomized clinical trial, the investigators will compare the ventilation efficacy of size 3 and size 4 i-gel® in anesthetized, paralyzed female patients weighing 50 to 60 kilograms who undergo breast surgery. Also, the investigators will record any side effects of size 3 and size 4 i-gel® in this cohort.
