Review Meta Analysis
Efficacy and adverse effects of buprenorphine in acute pain management: systematic review and meta-analysis of randomised controlled trials.
Buprenorphine appears to have a ceiling effect on respiratory depression, but not analgesia in healthy young patients. However, the efficacy and side-effects of buprenorphine in the setting of acute pain are poorly characterized. The aim of this study was to characterize the analgesic efficacy and adverse effects of buprenorphine compared with morphine in the acute pain setting. ⋯ There was only one secondary outcome with an overall significant difference; buprenorphine use was associated with significantly less pruritus (OR=0.31; 95% CI=0.12-0.84; I2=6%; P=0.02). Whilst a theoretical ceiling effect may exist with respect to buprenorphine and respiratory depression, in a clinical setting, it can still cause significant adverse effects on respiratory function. However, given that buprenorphine is an equally efficacious analgesic agent, it is a useful alternative opioid because of its ease of administration and reduced incidence of pruritus.

Videolaryngoscopy versus direct laryngoscopy for emergency orotracheal intubation outside the operating room: a systematic review and meta-analysis.
Videolaryngoscopy may improve first-pass success in the ICU and among less experienced practitioners outside the operating theatre.

Randomized Controlled Trial
Non-invasive positive-pressure ventilation with positive end-expiratory pressure counteracts inward air leaks during preoxygenation: a randomised crossover controlled study in healthy volunteers.
During preoxygenation, the lack of tight fit between the mask and the patient's face results in inward air leak preventing effective preoxygenation. We hypothesized that non-invasive positive-pressure ventilation and positive end-expiratory pressure (PEEP) could counteract inward air leak. ⋯ NCT03087825.

Randomized Controlled Trial Multicenter Study
Effect of goal-directed haemodynamic therapy on postoperative complications in low-moderate risk surgical patients: a multicentre randomised controlled trial (FEDORA trial).
The aim of this study was to evaluate postoperative complications in patients having major elective surgery using oesophageal Doppler monitor-guided goal-directed haemodynamic therapy (GDHT), in which administration of fluids, inotropes, and vasopressors was guided by stroke volume, mean arterial pressure, and cardiac index. ⋯ ISRCTN93543537.

Review Meta Analysis
Should continuous rather than single-injection interscalene block be routinely offered for major shoulder surgery? A meta-analysis of the analgesic and side-effects profiles.
Major shoulder surgery is associated with moderate-to-severe pain, but consensus on the optimal analgesic approach is lacking. Continuous catheter-based interscalene block (CISB) prolongs the analgesic benefits of its single-injection counterpart (SISB), but concerns over CISB complications and difficulties in interpreting comparative evidence examining major and minor shoulder procedures simultaneously, despite their differences in postoperative pain, have limited CISB popularity. This meta-analysis evaluates the CISB analgesic role and complications compared with SISB for major shoulder surgery. ⋯ High-level evidence indicates that CISB provides superior analgesia up to 48 h after major shoulder surgery, without increasing side-effects, compared with SISB. The importance of CISB-related changes in respiratory indices is questionable.
