Patient-controlled Sedation During Flexible Bronchoscopy: A Randomized Controlled Trial

Patient-controlled Sedation During Flexible Bronchoscopy: A Randomized Controlled Trial:


Abstract

Background:

Patient-controlled sedation (PCS) is a documented method for endoscopic procedures considered to facilitate early recovery. Limited data have been reported, however, on its use during flexible bronchoscopy (FB).

Methods:

This study hypothesized that PCS with propofol during FB would facilitate early recovery, with similar bronchoscopist and patient satisfaction compared with nurse-controlled sedation (NCS) with midazolam. A total of 150 patients were randomized 1:1:1 into a control group (premedication with morphine-scopolamine and NCS with midazolam), PCS-MS group (premedication with morphine-scopolamine and PCS with propofol), and PCS-G group (premedication with glycopyrronium and PCS with propofol).

Results:

The procedures included transbronchial biopsy, transbronchial needle aspiration, cryotherapy/biopsy, and/or multistation endobronchial ultrasound. FB duration values in median (range) were 40 (10 to 80), 39 (12 to 68), and 44 (10 to 82) minutes for the groups NCS, PCS-MS, and PCS-G, respectively. An overall 81% of the patients in the combined PCS groups were ready for discharge (modified Post Anaesthetic Discharge Scoring System, score 10) 2 hours after bronchoscopy compared with 40% in the control group (P<0.0001). Between PCS groups, 96% of the PCS-G group patients were ready for discharge compared with 65% in the PCS-MS group (P=0.0002) at 2 hours. Bronchoscopists’ and patients’ satisfaction scores were high in all groups. Postdischarge quality scores showed no differences among the groups.

Conclusion:

PCS with propofol during FB is feasible, as it shortened recovery time without compromising procedure conditions for bronchoscopists or patients. A rapid postsedation stabilization of vital signs facilitates surveillance before the patient leaves the hospital.
