Shands Teaching Hosp and Clinic Inc. v. DunnTrial court committed reversible error when it refused to grant hospital a continuance until nurse, who was pregnant and was advised by her doctor not to travel to trial, could appear in person and testify before the jury, in medical malpractice case against hospital that alleged nurse failed to monitor patient after open heart surgery and administered an overdose of medication; no other witness could give testimony in place of nurse, as the claim against hospital was based solely on the allegation that nurse was negligent, the hospital sought a continuance three months before trial, and the denial of the motion prevented the jury from hearing nurse's live testimony.
