Hoarseness of voice had completely disappeared by 4 th hr in either group. Our study however offers almost no conclusive evidence of unflinching safety of the device, which requires data from a considerably larger cohort in a routine practice. Devices with an inflatable mask have the potential to cause tissue distortion, venous compression, and nerve injury, which explains the increased incidence of associated postoperative morbidity. Table 3 Fiberoptic scoring system[ 6 — 8 ]. In an earlier pilot study, we found mean sealing pressures of Prospective, randomized, ethical issues committee approved interventional study. Known difficult airway, 2.

A new single use supraglottic airway device with a non-inflatable cuff and an esophageal vent: Results The demographic profiles of patients in both the groups were similar [ Table 4 ]. Anasthesiol Intensivmed Notfallmed Schmerzther. These observations are in close approximation to the results reported by others.

None of the patients had dysphonia or any other complications in either of the groups. Eur J Anaesthesiol ; Indian J Anaesth ; Cervical thesiss disease, 3. Both groups were compared with respect to ease of insertion, insertion attempts, fiberoptic assessment, airway sealing pressure, ease of gastric tube placement, and other complications. Laryngo-pharyngeal complaints after use of the laryngeal mask airway.

Ours is a mean value where as Laffey et al reported it as median value.

Operating rooms of Khoula Hospital, Muscat Oman. The amount of air removed was recorded. Both lm the groups were comparable with respect to sex distribution, SAD size used and the duration of anesthesia. Swelling and cyanosis of the tongue associated with use of a laryngeal mask airway. At the conclusion of surgery, residual neuromuscular paralysis was reversed using a mixture of neostigmine and glycopyrrolate.

Can J Anaesth ; Once adequate depth of anesthesia was achieved either of the 2 devices, selected using a random computerized table, was inserted by an experienced anesthesiologist. There was no evidence of airway trauma, regurgitation and aspiration.

This was recorded with the head resting over a 6 cm head ring Table 3. The average airway sealing pressure was reported as The demographic profiles of patients in both the groups were similar [ Table 4 ]. Intraoperatively, all patients received one gram of paracetamol as intravenous infusion. Fiberoptic scoring system[ 6 — 8 ].

Hoarseness of voice had completely disappeared by 4 th hr in either group. Demographic data Click here prozeal view. Both the devices were fixed by taping the tube over the chin and a well-lubricated gastric tube was introduced into the stomach through the gastric port. Regurgitation of gastric contents was also assessed.

Open in a separate window. The mean airway sealing pressure in the PLMA group Insertion time needed for placement of the SAD was defined as time in seconds from SAD touching the teeth to the first recorded near rectangular capnogram curve.


Bilateral hypoglossal nerve injury following the use of the laryngeal mask airway. In conclusion, findings of this study support our hypothesis that BM takes significantly shorter placement time and provides a better seal as compared to PLM but without any reduction in laryngo-pharyngeal morbidity.

Adults of either sex, 2. In the present study use of the PLMA is associated with a higher incidence of pharyngolaryngeal morbidity blood staining of the device, sore throat, and dysphagia in comparison to the I-gel. A novel thseis airway without inflatable cuff.
