PURPOSE To compare the cardiopulmonary effects and the quality of anesthesia of the extradural lidocaine in combination with fentanyl or morphine in bitches undergoing ovariohysterectomy. METHODS Sixteen female dogs, were sedated with intramuscular acepromazine (0.05 mg kg-1), followed by anesthetic induction with intravenous propofol (4 mg kg-1), to perform the lumbosacral puncture. The anim...

A 3-year-old boy had had a soft-tissue swelling in the left temporal region for 6 months. The swelling was gradually increasing in size and had been associated with progressive diminution of vision for 4 months. Physical examination revealed perception of light only in the right eye and complete loss of vision in the left eye. The temporal swelling was cystic, nontender, and associated with for...

BACKGROUND AND PURPOSE We adopted an imaging algorithm in 2011 in which extradural fluid on spinal MR imaging directs dynamic CT myelography. We assessed algorithm compliance and its effectiveness in reducing repeat or unnecessary dynamic CT myelograms. MATERIALS AND METHODS CT myelograms for CSF leaks from January 2011 to September 2014 were reviewed. Patients with iatrogenic leaks, traumati...

The effects of extradural and general anaesthesia on the adrenocortical response to elective or emergency Caesarean section were studied in 72 patients. Maternal plasma concentrations of cortisol were measured before surgery, at delivery, and 30 and 60 min after skin incision. Umbilical vein and artery plasma cortisol concentrations at delivery were determined also. Maternal plasma cortisol con...

Sir,—We are grateful for the opportunity to reply to the letter from Drs Jones and Nixon, comparing the results of their audit of postoperative extradural analgesia with our own published results. It would appear from the results of Dr Jones and colleagues that the use of extradural fentanyl—bupivacaine mixtures was associated with less hypotension and better pain relief than the diamorphine-bu...

Forty-six dogs with either cervical (C1-C5 or C6-T2) or thoracolumbar (T3-L3) acute myelopathy underwent prospective conventional computed tomography (CT), angiographic CT, myelography, and CT myelography. Findings were confirmed at either surgery or necropsy. Seventy-eight percent of lesions were extradural, 11% were extradural with an intramedullary abnormality, 7% were intramedullary, 2% wer...

We have measured spinal segmental levels of anaesthesia to light touch (LT), pinprick (PP) and cold temperature discrimination (TE) during 2% lignocaine extradural anaesthesia in 22 patients, to determine if zones of differential sensory block develop during extradural anaesthesia and, if so, the extent to which TE extends beyond PP or LT levels and how age affects differential block. The media...

EDH is most often due to a fractured temporal or parietal bone damaging the middle meningeal artery or vein, with blood collecting between the dura and the skull. It is typically caused by trauma to the temple just beside the eye, although it may also follow a tear in dural venous sinuses. Children are less likely than adults to have an associated skull fracture. EDH in the spinal column may fo...
