Remifentanil injected during analepsia shortens length of postanesthesia care unit stay in patients undergoing laparoscopic surgery for endometrial cancer: a randomized controlled trial.

Background: To guarantee efficient operating room (OR) activity, tracheal extubation is often performed in the postanesthesia care unit (PACU). Therefore, the ability of PACU to accommodate postoperative patients is crucial. Optimizing extubation management may speed up the turnover of PACU beds.

[Effects of preloading epidural space with epinephrine (1:200 000) on the incidence of vascular injuries through the insertion of an epidural catheter during cesarean section].

Objective: To evaluate the effects of preloading epidural space with epinephrine (1:200 000) on the incidence of vascular injuries through the insertion of an epidural catheter during cesarean section.

Methods: Between May 2011 and December 2011, upon obtaining institutional ethics approval and informed consent from the Human Ethics Committee of Nanjing Medical University, 100 laboring women with singleton cephalic presentation at term, ASA (American Society of Anesthesiologists) class I-II, undergoing caesarean section under continuous epidural analgesia were randomly divided into E and N groups according to a random digit table (n = 50 each). After an identification of epidural space, 5 ml of normal saline with epinephrine (1:200 000) was injected into epidural space in group E and 5 ml of normal saline in group N through an epidural needle.
