Eliminating intensive postoperative care in same-day surgery patients using short-acting anesthetics.

Background: A multidisciplinary effort was undertaken to determine whether patients could safely bypass the postanesthesia care unit (PACU) after same-day surgery by moving to an earlier time point evaluation of recovery criteria.

Methods: A prospective, outcomes research study with a baseline month, an intervention month, and a follow-up month was designed. Five surgical centers (three community-based hospitals and two freestanding ambulatory surgical centers) were utilized.

Dolasetron for the prevention of postoperative nausea and vomiting following outpatient surgery with general anaesthesia: a randomized, placebo-controlled study. The Dolasetron PONV Prevention Study Group.

In a multicentre, randomized, double-blind, placebo-controlled dose-ranging study, 1030 patients undergoing outpatient surgery with general anaesthesia received i.v. dolasetron mesylate (12.

A comparison of the efficacy, safety, and patient satisfaction of ondansetron versus droperidol as antiemetics for elective outpatient surgical procedures. S3A-409 and S3A-410 Study Groups.

Unlabelled: Two identical, randomized, double-blind, placebo-controlled studies enrolled 2061 adult surgical outpatients at high risk of postoperative nausea and vomiting (PONV) to compare i.v. ondansetron 4 mg with droperidol 0.

A multicenter comparison of maintenance and recovery with sevoflurane or isoflurane for adult ambulatory anesthesia. The Sevoflurane Multicenter Ambulatory Group.

Sevoflurane was compared with isoflurane in 246 adult ASA class I-III patients undergoing ambulatory surgery. After administration of midazolam 1-2 mg and fentanyl 1 microgram/kg, anesthesia was induced with propofol 2 mg/kg and maintained with either sevoflurane or isoflurane in 60% nitrous oxide to maintain arterial blood pressure at +/- 20% of baseline. Fresh gas flows were 10 L/min during induction and 5 L/min during maintenance.

A double-blind, placebo-controlled pilot study examining the effectiveness of intravenous ondansetron in the prevention of postoperative nausea and emesis.

Study Objective: To compare the efficacy and safety profiles of ondansetron and a placebo when infused immediately prior to anesthesia induction for the prevention of postoperative nausea and emesis (vomiting or retching).

Design: Randomized, double-blind, placebo-controlled, parallel, multicenter pilot study.

Setting: Three U.

Treatment of postoperative nausea and vomiting after outpatient surgery with the 5-HT3 antagonist ondansetron.

Background: Postoperative nausea and vomiting following outpatient surgery can significantly delay discharge. This study evaluates the safety and efficacy of ondansetron (a new 5-HT3 antagonist) in the treatment of postoperative nausea and vomiting in patients following outpatient surgery.

Methods: Five hundred outpatient surgical patients (53 male and 447 female), receiving general endotracheal anesthesia, were studied at ten centers.

Ondansetron in the treatment of postoperative nausea and vomiting in ambulatory outpatients: a dose-comparative, stratified, multicentre study.

The safety and efficacy of ondansetron were evaluated in the treatment of postoperative nausea and vomiting. Five hundred patients who experienced nausea or vomiting in the Post-Anaesthesia Care Unit within the first 2 h of recovery were randomized to receive either 1, 4, or 8 mg of ondansetron, or placebo. All patients had undergone ambulatory surgery with general endotracheal anaesthesia.

Safety of outpatient cerclage.

One hundred one women who underwent scheduled McDonald cerclage were studied. Fifty outpatients were reviewed prospectively, and 51 inpatients were studied retrospectively and concurrently. Forty-five outpatients and 48 inpatients completed pregnancy.

A comparison of recovery in outpatients receiving fentanyl versus those receiving butorphanol.

The frequency of postanesthesia side effects and times to reach "benchmarks" in the recovery process for IV preinduction doses of 20 micrograms/kg butorphanol, 40 micrograms/kg butorphanol, or a 2 micrograms/kg dose of fentanyl were compared in a double-blinded study involving ambulatory surgical patients. The authors hypothesized that all drugs would perform equally well in all study areas. Sixty ASA physical status I and II women undergoing laparoscopic tubal sterilization were randomly assigned to one of three groups: Group I (n = 20) received 20 micrograms/kg butorphanol as a preinduction agent; Group II (n = 20) received 40 micrograms/kg butorphanol; Group III (n = 20) received 2 micrograms/kg fentanyl.

Bupivacaine infiltration of the mesosalpinx in ambulatory surgical laparoscopic tubal sterilization.

Bupivacaine infiltration of the mesosalpinx was compared to lidocaine, normal saline or no injection for pain relief in women having elective laparoscopic tubal sterilization by Yoon fallopian ring application. One hundred women were assigned randomly to four groups. In a double-blind study, the mesosalpinx was infiltrated in three groups: Group 1 - lidocaine one per cent; Group II - bupivacaine 0.

Infiltration of the mesosalpinx for pain relief after laparoscopic tubal sterilization with Yoon rings.

Approximately 200 women of American Society of Anesthesiologists class I and II physical status electing outpatient laparoscopic tubal sterilization with Yoon rings were involved in a double-blind study to evaluate postoperative pain relief after intraoperative suprapubic infiltration of the fallopian mesosalpinx. The postoperative pain levels were lower after bilateral infiltration of 0.5% bupivacaine beneath the site of ring application.

Outpatient general and spinal anesthesia.

By the year 1990, it is projected that 50 per cent of all surgery in the United States will be performed on an outpatient basis. Both surgeons and anesthesiologists must understand patient and procedure prerequisites for outpatient surgery. The surgeon, prior to scheduling the operation, must evaluate the patient as to acceptability and provide that patient with complete information about the proposed outpatient experience.

Patient selection criteria for 1987.

Patient selection criteria provides an effective means for assessing the appropriateness of patients for surgery in an outpatient setting. Thorough evaluation in each of the five criteria areas helps ensure the acceptability of each patient for ambulatory surgery. Regardless of the development of new procedures, anesthetic agents, and equipment, the use of patient selection criteria is still one of the most important factors in determining the overall outcome and success of the patient's ambulatory surgery experience.
