Preoperative anxiety: detection and contributing factors

Early anesthesia evaluation of the ambulatory surgical patient: does it really help?

STUDY OBJECTIVE

To evaluate whether early evaluation by the anesthesiologist is more beneficial for the ambulatory surgical patient than a day-of-surgery visit.

DESIGN

A randomized study evaluating patients with different surgical procedures.

SETTING

Ambulatory surgical outpatients at a university-affiliated integrated ambulatory surgical unit.

PATIENTS

Sixty-three ASA physical status I and II women scheduled to undergo elective dilatation and curettage or gynecologic laser surgery.

INTERVENTIONS

Approximately half of the patients received an early (1 to 7 days preoperative) anesthesia evaluation, and half received a day-of-surgery evaluation. All patients underwent the surgical procedures with a standardized general anesthetic.

MEASUREMENTS AND MAIN RESULTS

The effect of an early versus a day-of-surgery anesthesia visit was evaluated with regard to patient anxiety levels; patient satisfaction with the surgical and anesthetic experience; operating room, recovery room, and ambulatory surgery unit time; anesthetic and analgesic requirements; and frequency of postoperative problems within 72 hours at home. There were no differences between the groups in demographic characteristics, anesthesia or analgesic requirements, degree of satisfaction with the ambulatory surgical experience, time spent in recovery room, or frequency of problems on postoperative follow-up. We were unable to demonstrate any differences between those patients seen early versus those seen on the day of surgery in anxiety levels preoperatively and postoperatively.

CONCLUSIONS

Healthy ASA physical status I and II ambulatory surgical patients do not benefit from reducing preoperative anxiety by visiting the anesthesiologist prior to the day of surgery.

Self-administration of midazolam for postoperative anxiety: a double blinded study

Anxiety is almost inevitably present in patients facing surgery. The optimal management of postoperative pain requires the acknowledgement of perioperative anxiety and the inclusion of pharmacological and/or non-pharmacological means of alleviating the fear and worry inherent in the surgical experience. In a double-blind randomized design, 39 patients undergoing total abdominal hysterectomies were given postoperative access to a standard patient-controlled analgesia (PCA) morphine pump for pain and a PCA pump dispensing either low-dose midazolam or saline for anxiety. Measures of anxiety and pain were completed pre-operatively and for 2 days postoperatively. Utilization of morphine and 'anxiolytic agent' were recorded. Analysis of covariance was applied to the data to control for the imbalance of cancer patients between the 2 groups. While both groups of patients chose to utilize their 'anxiety pump' throughout the study, those patients receiving midazolam had significantly lower postoperative Spielberger State Anxiety scores and visual analogue scale anxiety scores. Patient-controlled midazolam in doses used in this study were safe and effective in managing anxiety but did not influence pain scores or the amount of PCA morphine patients used. Pre-operative levels of depression were significantly associated with postoperative pain levels independent of treatment group or cancer diagnosis.
