Increased resting bronchial tone in normal subjects acclimatised to altitude

Thorax (2002)

Charlton Wilson S E Bakewell Murray Miller Nancy Hart R.C.N. McMorrow

Normal subjects frequently experience troublesome respiratory symptoms when acclimatised to altitude. Bronchial hyperresponsiveness (BHR) and full and partial flow-volume loops were measured before and after ascent to 5000 m altitude to determine if there are changes in resting bronchial tone and BHR that might explain the symptoms.BHR to histamine was measured using a turbine spirometer to record partial and full flow-volume curves and expressed as log dose slopes. Twenty one subjects were tested at sea level and after acclimatisation at 5000 m altitude.No significant change in log dose slope measurements of forced expiratory volume in 1 second occurred after acclimatisation, and the maximal expiratory flow with 30% of forced vital capacity remaining (MEF(30%)) rose on the full loop and fell on the partial loop. Their ratio (full divided by partial) rose on average by 0.28 (95% confidence limits 0.14 to 0.42) from the mean (SD) sea level value of 0.87 (0.20).There is no increase in BHR in normal subjects acclimatised to altitude but an increase in resting bronchial tone occurs that could be released by deep inspiration. This may be the result of increased cholinergic tone.

A new mirrored laryngoscope*

Anaesthesia (2003)

R.C.N. McMorrow R. K. Mirakhur

Summary A new laryngoscope has been designed, incorporating an adjustable mirror and a levered tip similar to the McCoy blade, in an attempt to bridge the gulf between simple direct laryngoscopy and fiberoptic laryngoscopy. Manual in‐line neck stabilisation was used to simulate difficult laryngoscopy in 14 anaesthetised patients after full neuromuscular blockade. The best view at laryngoscopy was assessed using a standard Macintosh laryngsocope, a size 3 McCoy laryngoscope and the mirrored laryngoscope. The best laryngeal view obtained in all cases with the Macintosh blade was a grade 3. The mirrored laryngoscope improved this view in 10 cases (71%) compared with five cases (36%) with the McCoy laryngoscope (p = 0.005); in seven cases (50%), the view improved to a grade 1 compared with no cases when the McCoy was used (p = 0.02). We conclude that the mirrored laryngoscope offers considerable advantages over the Macintosh and the McCoy laryngoscopes in simulated difficult laryngoscopy, is simple to use and requires no special training.

A new mirrored laryngoscope for difficult intubation

Anaesthesia (2002)

R.C.N. McMorrow R. K. Mirakhur

Intubation is a common requirement for anaesthesia, and a laryngoscope is commonly used to view the larynx to allow the introduction of the tracheal tube. The view obtained at laryngoscopy is graded on a 1–4 scale [1]. Grades 1 and 2 usually provide little difficulty with intubation; however, Grades 3 and 4 often present considerable difficulty and intubation may be impossible using a standard laryngoscope. The levering laryngoscope was designed in an attempt to improve the view during difficult laryngoscopy [2]. However, it has been reported to improve the laryngeal view in only 44–56% of difficult cases [3], deteriorate the view in up to 12% of cases and to be of little or no benefit in a Grade-4 larynx [4]. A modification to the levering laryngoscope has been designed in an attempt to improve the view at laryngoscopy further. The mirrored laryngoscope (Figure) is based on the levering laryngoscope but differs from it in three respects: it has a deployable arm, an adjustable mirror and an additional connecting shaft. This allows the controlled placement of a mirror in the posterior oropharynx, providing the anaesthetist with an additional 60° field of view in addition to that provided by a standard Macintosh blade. Control of the pitch of the mirror and deployment of the arm and flexible tip are all provided in one smooth movement of the anaesthetist's thumb on the single control lever, in a similar manner to that employed by the levering laryngoscope. In its resting state the mirrored laryngoscope has the same internal contours as a standard Macintosh blade, yet is no larger than the dimensions of a standard levering laryngoscope. Early pilot study results indicate that the mirrored laryngoscope blade would have significant advantages over existing laryngoscope blades. Mirrored laryngoscope.
