Unilateral malignant hyperinflation of the lungs during positive pressure mechanical ventilation was described during aggressive respiratory therapy of unilateral lung disease or in situations of significant difference in compliance between the two lungs. We report a case of malignant hyperinflation of the nondependent lung during chest surgery. The differential diagnosis and treatment with differential lung ventilation are described.

Case Reports
Hypoxic brain damage after intramuscular self-injection of diclofenac for acute back pain.
We present a case of hypoxic brain damage that occurred after intramuscular injection of diclofenac due to a severe anaphylactic reaction. A 38-year-old nurse treated herself for acute lower back pain with 100 mg diclofenac intramuscularly. Five minutes later, she collapsed and developed coma and respiratory arrest. ⋯ Magnetic resonance imaging and computerized tomography showed signs of hypoxic brain injury and the patient died from central cardiopulmonary failure 7 days later. Intramuscular treatment with non-steroidal anti-inflammatory drugs such as diclofenac has rare but potentially severe side-effects. Therefore, intramuscular injections are inappropriate and should be replaced with oral or rectal treatment, which has similar absorption profiles.

Case Reports
The anaesthetic management of a case of severe upper airways obstruction due to an enlarging subglottic benign polyp.
The use of a newly developed aid to jet ventilation of the lungs, a modified Ben-Jet tube (the Hunsaker Monjet tube), is described in a patient with partial upper airway obstruction. This report highlights an unusual use of this device. The Monjet is a fluoroplastic, monitored, self-centring, fine bore tube that can be inserted from the mouth through to the subglottic region. It was originally developed to anaesthetize healthy patients without airway obstruction who were undergoing suspension microlaryngoscopy.

Comparative Study
Colour Doppler imaging of the interspinous and epidural space.
In recent studies, ultrasonic diagnostic imaging has proved useful in the screening of the trajectory of the epidural needle. With regard to possible side-effects of spinal and epidural anaesthesia caused by vessel injury, we aimed to evaluate the usability of Colour Doppler imaging for the depiction of interspinous vessels in prepuncture examination. ⋯ Prepuncture Doppler imaging can provide the epiduralist with information regarding the position of vessels in the needle trajectory. This might help to reduce complications in regional anaesthesia.

We present the anaesthetic management of a patient for stenting of a thoracic aortic aneurysm at the site of an aortic coarctation. The specific challenges to the anaesthetist for this case are outlined. These include the specific problems of placing the graft, the obvious risk of aortic rupture and the unfamiliar environment of the separate radiological theatre. The advantages and disadvantages to the anaesthetist of the treatment of thoracic aortic aneurysms with stents are briefly discussed.
