70

Results

The ED95 for success (main) was 12.6mg. The incidence of respiratory discomfort and maternal satisfaction scores did not differ significantly between dose groups. Phenylephrine dose and nausea/vomiting incidence increased with increasing doses of bupivacaine.

Baseline Characteristics

Healthy, term parturients who were scheduled for elective cesarean delivery were enrolled.

Participant flow

Patients were randomized, according to a computer-generated randomization list using sealed opaque envelopes, into seven groups. The patient and assessing investigator were blinded to group allocation. On the day of surgery the envelope was handed to an anesthesiologist not involved in the study who prepared the study medications. The study medication was given to the blinded anesthesiologist having charge of perioperative anesthetic management before induction of anesthesia.

Adverse events

none

Outcome measures

Effective doses for 50% (ED50) and 95% (ED95) of subjects required for successmain during cesarean delivery.
