A survey of predoctoral pediatric dentistry programs in American dental schools was conducted to determine the extent of didactic and clinical training in pediatric conscious sedation. Fifty-four of 59 programs (92 percent) returned usable surveys. The results indicated that there exists a wide range of teaching practices, both in numbers and types of sedations experienced. ⋯ Predoctoral programs without an affiliated postdoctoral program were much more likely to practice conscious sedation than those that trained postdoctoral students. The reason most frequently listed for the nonuse of sedation in the predoctoral clinic was philosophical opposition to pharmacological management at this level of training. A majority of the respondents believed that improved monitoring practices and documentation of cases would result from the recent adoption by the American Academy of Pediatric Dentistry of guidelines for conscious sedation.

[Controlled hypotension during posterior vertebral arthrodesis; value of an isoflurane-nitroglycerin combination].
Eighteen young patients (mean age +/- SD 15.9 +/- 3.3) scheduled for operative treatment of idiopathic scoliosis (posterior spine fusion) were studied during surgery. Deliberate hypotension (MAP less than 60 mm Hg) of long duration (greater than 2 hours) was induced using isoflurane and nitroglycerin. Hypotension was effective in less than 15 min in all patients. ⋯ Intra operative awakening was obtained 22.8 +/- 3.7 min after isoflurane was discontinued. Isoflurane and nitroglycerin produce a stable and safe hypotension with no major hemodynamic disturbances. Isoflurane has to be discontinued 20 min before the wake-up test.

A patient with Friedreich's ataxia was anaesthetised on two occasions. The neuromuscular blocking agent was atracurium 0.5 mg/kg on the first occasion and tubocurarine 0.5 mg/kg on the second. ⋯ This patient did not demonstrate an abnormal response to either relaxant; the operating conditions were satisfactory and recovery was not delayed. These drugs may be safely used in this condition provided that monitoring is adequate.

Randomized Controlled Trial Comparative Study Clinical Trial
Spinal or general anaesthesia for surgery of the fractured hip? A prospective study of mortality in 578 patients.
The mortality following surgical correction of upper femoral fractures was investigated in 578 patients, over the age of 50 yr, randomly allocated to receive spinal (bupivacaine) or general (enflurane or neurolept) anaesthesia. Thirty days after surgery the mortality was 6% after spinal and 8% after general anaesthesia (ns). ⋯ The estimated blood loss was smaller (P less than 0.05) in patients receiving spinal anaesthesia. Regardless of the anaesthetic technique, a high short-term mortality was related to age, male sex, and trochanteric fracture, whereas excess long-term mortality was related to male sex and high ASA scores.
