Clinical TrialAccuracy of ProSeal™ laryngeal mask airway intracuff pressure estimation using finger palpation technique - a prospective, observational study.
The incidence of pharyngolaryngeal adverse events associated with laryngeal mask airways can be reduced by the use of manometry to limit the laryngeal mask airway intracuff pressures. We conducted a prospective, observational study in 80 patients undergoing general anaesthesia with the ProSeal™ laryngeal mask airway to determine the accuracy of a finger palpation technique compared to actual readings obtained from a hand-held manometer by different anaesthesia personnel. The strength of association of estimated versus actual intracuff pressures, R, for nurse anaesthesia assistants, junior anaesthetists and senior anaesthetists were 0.21 (weak), 0.35 (moderate) and 0.78 (strong) respectively. ⋯ In all groups, the palpation technique tended to underestimate the actual intracuff pressure by a mean of 10.3 cmH2O. Palpation accuracy decreased when actual intracuff pressures were >80 cmH2O. These findings suggest that cuff pressure manometry should be recommended as standard of care with the use of laryngeal mask airways.

Case ReportsSuccessful perioperative management of a patient with C1 esterase inhibitor deficiency with a novel bradykinin receptor B2 antagonist.
We present the case of a 28-year-old female with a previous diagnosis of C1 esterase inhibitor deficiency presenting for dental extractions under general anaesthesia. Following prophylaxis with a new bradykinin receptor 2 antagonist (icatibant), surgery was carried out uneventfully with an unremarkable postoperative course.
