Randomized Controlled Trial Comparative Study Clinical Trial
Etomidate and methohexitone. A comparative clinical study in out-patient anaesthesia.
Etomidate compares favourably with methohexitone as an intravenous induction agent in out-patient anaesthesia excluding the incidence of involuntary muscle movement. The use of propylene glycol as a solvent for etomidate does not alter the previously claimed advantageous features of this agent.

Randomized Controlled Trial Clinical Trial
Directional spinals in obstetric analgesia.
Directional characteristics of spinal injections delivered via a 22 gauge Whitacre needle were confirmed in twenty-one obstetric patients undergoing elective Caesarean section. Caudad injection was inadequate for elective Caesarean section, while cephalad or lateral injection provided good sensory levels for the duration of the surgery. It is speculated that along with the low incidence of postspinal headache and ease of administering the block with a more rigid 22 gauge needle, low dose caudally directed injections may provide a superior means of administering saddle block analgesia for obstetric patients.
