Safety of Driving After Minor Surgery with Monitored Anesthesia Care

Phase 4

Active, not recruiting

• Conditions: Minor Surgical Procedures with Monitored Anesthesia Care; Driving Performance After Minor Ambulatory Surgery
• Interventions: Drug: Midazolam; Drug: Sufentanil; Drug: Propofol

• Registration Number: NCT00577200
• Lead Sponsor: Rush University Medical Center

Brief Summary

Patients are currently advised to refrain from driving motor vehicles or using public transportation unescorted for a 24 hour period if they undergo any minor ambulatory surgical procedure with monitored anesthesia care (MAC).However, recently introduced short-acting anesthetics may facilitate rapid recovery and an early return to normal daily activities. The proposed study will compare newer short-acting anesthetic agents (propofol, benzodiazepine, opioid) utilized in MAC, to determine if a particular pharmacological agent, or a combination of agents, impair driving performance as evaluated by driving simulator assessment, at time of discharge from the ambulatory center after minor surgical procedures.Subjects will be grouped as patients with chronic pain undergoing procedures and those without chronic pain undergoing procedures. Subjects with pain issues will be randomized with either 1)Midazolam + Sufentanil + Propofol or 2)Midazolam + Sufentanil. There will be a third group of subjects who are controls not undergoing any procedures.

Detailed Description

Patients are currently advised to refrain from driving motor vehicles or using public transportation unescorted for a 24 hour period if they undergo any minor ambulatory surgical procedure with monitored anesthesia care (MAC).However, recently introduced short-acting anesthetics may facilitate rapid recovery and an early return to normal daily activities. The proposed study will compare newer short-acting anesthetic agents (propofol, benzodiazepine, opioid) utilized in MAC, to determine if a particular pharmacological agent, or a combination of agents, impair driving performance as evaluated by driving simulator assessment, at time of discharge from the ambulatory center after minor surgical procedures.The three critical measures of driving performance selected are: weaving, reaction time, and number of collisions. If any of the experimental MAC conditions shows statistical equivalence at discharge with baseline, for all three criterion measures, then that anesthetic regimen can be designated as "safe to drive". If this study can demonstrate such an early recovery of driving ability, which is probably the most complex and dangerous activity commonly encountered, this begs the re-examination of all post-operative activity restrictions imposed on this patient population. Subjects will be grouped as patients with chronic pain undergoing procedures and those without chronic pain undergoing procedures.Subjects with pain issues will be randomized with either 1)Midazolam + Sufentanil + Propofol or 2)Midazolam + Sufentanil. There will be a third group of subjects who are controls not undergoing any procedures.

Recruitment & Eligibility

• Status: ACTIVE_NOT_RECRUITING
• Sex: All
• Target Recruitment: 625

Inclusion Criteria

• Ambulatory surgical patient possessing a valid driving license and presenting for a minor procedure that does not physically impact ability to drive (such as hand, arm, and lower extremity surgery).
• Another group of subjects who are not scheduled for a procedure will be given a driving simulator exercise and they will be control group.

Exclusion Criteria

• Any surgical case that lasted more than one hour and required general anesthesia will be excluded.
• Patients with a history of chronic benzodiazepine or alcohol abuse, alcohol or other substance dependence or recent use of medications with sleep altering qualities, and driving simulator sickness.
• Patients who cannot follow a simple driving task and cannot sit on a chair for the driving test due to medical conditions will also be excluded.
• History of seizures
