The Perilaryngeal Airway and the Laryngeal Tube in Short Ophthalmic Procedures in Adults: A Prospective Randomized Comparative Study

Abstract

in certain cases, general anesthesia is indicated, as in uncooperative, demented, anxious or deaf patients. Sometimes, general anesthesia is used per patient request. Since 2003 is the laryngeal tube one of the most common used extraglottic devices for the airway management during eye operations. Recently we have got the perilaryngeal airway CobraPLA as an addition to the airway armamentarium that has been used also in eye surgery. This prospective randomized study aimed to determine whether the disposable PLA was as good in the airway management as the reusable LT. We hypothesized that there would be no difference between groups with regard to the primary study end-points: insertion time, oropharyngeal leak pressure. Secondary study end-points were ease of insertion, hemodynamic responses, peripheral oxygen saturation, end-tidal carbon dioxide and intra-operative and early postoperative adverse events.

Influence of head and neck positions on oropharyngeal seal pressure with Baska mask® versus I-gel™; A randomised clinical study

“…Ease of insertion was qualitatively evaluated using four-point scale. [ 8 ] The insertion time (the time between picking up the prepared mask and successful placement) was assessed in all the cases. The anatomical placement of both the devices in situ was assessed clinically and by fibreoptic evaluation (3.7 mm bronchoscope, Karl Storz, Tuttlingen, Germany)in neutral position based on Brimacombe scoring system.…”

Comparison of the Disposable Streamlined Liner of the Pharynx Airway and the Disposable I-gel in Anaesthetized, Paralyzed Adults: A Randomized Prospective Study

“…If the second attempt was also unsuccessful, despite adjustment maneuvers, a SAD failure was recorded and no further data were collected from that subject for the failed device. Ease of airway insertion which was qualitatively evaluated using the following 4-point scale [ 17 ]: 1: easy insertion on first attempt with no need for adjustment, 2: slightly difficult insertion on first attempt with at least one adjustment maneuver needed, 3: obviously difficult insertion on the second attempt, and 4: impossible (more than 2 attempts or no SAD insertion). The OSP being measured once an effective airway had been achieved using a fresh gas flow rate of 5 L/min, closing the adjustable pressure limiting valve of the anesthetic circuit and recording the pressure when gas was heard leaking around the device (assessed by listening over the mouth) [ 18 ].…”

Comparison of I-gel with Baska Mask Airway for Controlled Ventilation in Obese Patients Undergoing Ambulatory Surgery: A Prospective Randomized Trial

“…The ease of SAD insertion was qualitatively evaluated using the following 4-point scale [5,12]. A score 1 means easy insertion on first attempt with no need for adjustment, a score 2 is considered in case of slight difficult insertion on first attempt with at least one adjustment maneuver.…”
