Randomized Controlled Trial
Carbetocin at Cesarean delivery for labour arrest: a sequential allocation trial to determine the effective dose.
The aim of this study was to estimate the effective dose 90% (ED90) of carbetocin to provide adequate uterine tone at Cesarean delivery (CD) for labour arrest. ⋯ The ED90 of carbetocin at CD for labour arrest, as determined in our study, should be interpreted with caution since it may be underestimated. This dose is higher than the currently recommended dose of 100 µg at elective CD and should not be used routinely given the uncertainty regarding its efficacy and the high incidence of arrhythmias at higher doses. This trial was registered at ClinicalTrials.gov, number: NCT01725243.

Review Meta Analysis
Postoperative recovery after anesthesia in morbidly obese patients: a systematic review and meta-analysis of randomized controlled trials.
Obese patients present a challenge to safe general anesthesia because of impaired cardiopulmonary physiology and increased risks of aspiration and acute upper airway obstruction. Since studies are lacking regarding the postoperative effects on recovery from general anesthesia in morbidly obese patients, we conducted a systematic review and meta-analysis of recovery outcomes in morbidly obese patients who had undergone general anesthesia. ⋯ Postoperative recovery was significantly faster after desflurane than after sevoflurane, isoflurane, or propofol anesthesia in obese patients. No clinically relevant differences were observed regarding PACU discharge time, incidence of PONV, or postoperative pain scores. The systematic review was registered with PROSPERO (CRD42014009480).

Randomized Controlled Trial
Effect of superficial cervical plexus block on postoperative quality of recovery after anterior cervical discectomy and fusion: a randomized controlled trial.
Spine surgeries are increasingly being performed as a day or short-stay surgery programs. Peripheral nerve block provide site-specific pain relief with few side effects, thereby reducing surgical stress and enhancing quality of recovery. The aim of our study was to determine the effect of a superficial cervical plexus block (SCPB) on postoperative quality of recovery and analgesia in patients undergoing elective anterior cervical discectomy and fusion (ACDF). ⋯ We showed that preoperative SCPB is an effective strategy for improving the early quality of recovery in patients undergoing single- or two-level ACDF. Nevertheless, there was no impact on opioid consumption or discharge times. This trial was registered at www.clinicaltrials.gov (NCT01662219).

Randomized Controlled Trial
Combined saphenous and sciatic catheters for analgesia after major ankle surgery: a double-blinded randomized controlled trial.
Continuous sciatic nerve block is used for pain management following major ankle surgery. Pain from the saphenous nerve territory often persists. We conducted a double-blinded randomized placebo-controlled trial to evaluate the effect of a supplementary saphenous catheter in the proximal thigh combined with a popliteal sciatic catheter and single-shot saphenous nerve block after major ankle surgery. ⋯ A saphenous catheter with a low-dose continuous infusion of ropivacaine, as an adjunct to a sciatic catheter, had no effect on the postoperative analgesia after major ankle surgery when both catheters were inserted along the short axis of the nerves. This trial was registered at ClinicalTrials.gov (NCT01445210).
