Comparative Study
Orotracheal intubation in patients with potential cervical spine injuries. An indication for the gum elastic bougie.
The conditions for emergency tracheal intubation of patients with cervical spine injury were simulated in 157 patients during induction of anaesthesia for routine surgery. The view of the larynx obtained during laryngoscopy with the head in the optimum intubating position was compared with that obtained when manual in-line stabilisation of the cervical spine and cricoid pressure were used. During laryngoscopy with cervical stabilisation, the view of the larynx was reduced in 45% of patients, and in 22% of patients nothing was visible beyond the epiglottis. ⋯ In addition, five patients in this group could not be directly intubated. Using the gum elastic bougie all patients, including the failures from the visual group, were intubated within 45 s (median 25 s). We recommend the gum elastic bougie as an aid to intubating the patient with suspected cervical spine injury, particularly when the glottis is not immediately visible.

Case Reports
The management of anaesthesia for caesarean section in a patient with paroxysmal ventricular tachycardia.
We describe the successful management of general anaesthesia for Caesarean section in a patient with poorly controlled paroxysmal ventricular tachycardia of pregnancy. The use of alfentanil before laryngoscopy and tracheal extubation ensured cardiostability without compromising maternal or fetal wellbeing. General anaesthesia allows prompt cardioversion. We believe that in the presence of a life-threatening unstable cardiac rhythm this consideration outweighs any theoretical advantage of regional blockade.
