Fulltext Brain laryngeal mask--study in 50 spontaneously breathing patients

Reddy SV, Win N

Singapore Med J, 1990 Aug;31(4):338-40.

Brain laryngeal mask (BLM) was used to assess its suitability in 50 spontaneously breathing patients by one lecturer and 4 Medical Officers. Insertion of the laryngeal mask was successful at the first attempt in 42 patients, second attempt in 7 and third attempt in one. The incidence of airway obstruction secondary to downfolding of the epiglottis, which was corrected by reinsertion, was 16%. Post-operative complications included clenching of teeth in 5 patients, vomiting in 2 and excessive salivation in 3. The incidence of sore throat was 10%.

The Proseal laryngeal mask airway in children: a comparison between two insertion techniques

Teoh CY, Lim FS

Paediatr Anaesth, 2008 Feb;18(2):119-24.

The Proseal laryngeal mask airway (PLMA) is a relatively new supraglottic airway device with a drain tube to minimize the risk of gastric insufflation and aspiration. We compared introducer tool (IT) and gum elastic bougie (GEB)-guided techniques for insertion of the Proseal LMA in children.

INTRODUCTION: The Baska mask and i-gel are two new types of second-generation supraglottic airway devices. The aim of this study was to compare these two devices in terms of quality of insertion, quality of ventilation and post-insertion complications.

MATERIAL AND METHODS: A total of 80 adult patients who were scheduled for elective surgery under general anaesthesia were randomised to two groups: Group BM: Baska mask (n = 40) and Group IG: i-gel (n = 40). The assessment focused on ease of insertion, number of attempts, insertion time, number of corrective manoeuvres, oropharyngeal leak pressure, tidal volume, peak airway pressure (PAP) and post-insertion complications.

RESULTS: Group IG showed a significantly shorter median insertion time (13.3 [interquartile range, IQR 7.8] vs. 17.0 [IQR 9.6] s; P < 0.001), a higher percentage in the 'very easy' ease of insertion category (62.5% vs. 10.0%; P < 0.001), a higher percentage in the no corrective manoeuvre category (92.5% vs. 72.5%; P = 0.003) and a higher percentage in the no post-operative throat pain category (67.5% vs. 32.5%; P = 0.011) than Group BM. However, Group BM showed a significantly higher generated PAP than Group IG (12.7 [1.8] and 11.5 [2.2] cm H2O, respectively; P = 0.010). There were no significant differences in other parameters.

CONCLUSIONS: The i-gel was better than the Baska mask in terms of ease of insertion, speed of insertion, fewer corrective manoeuvres and less post-operative throat pain. However, the Baska mask had a better cuff seal, as shown by a higher generated PAP.

Fulltext Paediatric one lung anaesthesia by selective bronchial intubation

Lew YS

Singapore Med J, 2000 Aug;41(8):398-400.

PMID: 11256348

One lung anaesthesia in paediatric patients may not always be achievable by bronchial blockade or double lumen tube intubation due to inadequate experiences or facilities. We attempted to isolate right lung by selectively intubating the left bronchus with single lumen tube on a 10 kg child. Optimal surgical condition and satisfactory oxygenation achieved but complicated with severe respiratory acidosis. The possible causes for hypercapnea in this child were discussed.
