Randomized Controlled Trial Comparative Study
Role of contextualizing a crisis scenario on the performance of a cricothyrotomy procedural task.
Simulation is an important alternative to evaluate cricothyrotomy, a rare life-saving procedure. This crossover study aimed to determine whether contextualization of a crisis scenario would impact the performance of a cricothyrotomy procedural task. ⋯ Contextualization of a crisis scenario did not affect the performance of a cricothyrotomy procedural task on a tissue-mannequin simulator. These findings may have implications when considering the feasibility and cost-effectiveness for assessing the performance of cricothyrotomy procedural tasks.

Randomized Controlled Trial
Replacing a double-lumen tube with a single-lumen tube or a laryngeal mask airway device to reduce coughing at emergence after thoracic surgery: a randomized controlled single-blind trial.
Coughing episodes occur frequently at extubation after thoracic surgery, and this may be due in part to the double-lumen tube (DLT). In this study, the DLT was replaced with either a single-lumen endotracheal tube (ETT) or a laryngeal mask airway (LMA) device or left in place, and the incidence of coughing at emergence was compared between the three groups. ⋯ Coughing at extubation after thoracic surgery can be reduced if the DLT is replaced by an LMA-P before emergence. The number of patients in this trial was too small to evaluate the risks associated with exchanging the airway device. This trial was registered at ClinicalTrials.gov: NCT00925613.

Randomized Controlled Trial Comparative Study
The impact of two different inspiratory to expiratory ratios (1:1 and 1:2) on respiratory mechanics and oxygenation during volume-controlled ventilation in robot-assisted laparoscopic radical prostatectomy: a randomized controlled trial.
Volume-controlled ventilation with a prolonged inspiratory to expiratory ratio (I:E ratio) has been used to optimize gas exchange and respiratory mechanics in various surgical settings. We hypothesized that, when compared with an I:E ratio of 1:2, a prolonged I:E ratio of 1:1 would improve respiratory mechanics without reducing cardiac output (CO) during pneumoperitoneum and steep Trendelenburg positioning, both of which can impair respiratory function in robot-assisted laparoscopic radical prostatectomy. Furthermore, we evaluated its effect on oxygenation during robot-assisted laparoscopic radical prostatectomy. ⋯ Compared with an I:E ratio of 1:2, a ratio of 1:1 lowered Ppeak without reducing CO during pneumoperitoneum and steep Trendelenburg positioning. Nevertheless, our results did not support its use solely for improving oxygenation. This trial was registered at http://clinicaltrials.gov/ (NCT01892449).

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).

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).
