Review Meta Analysis
Prevention of hypotension after spinal anaesthesia for caesarean section: a systematic review and network meta-analysis of randomised controlled trials.
Vasopressors are the most effective method for preventing maternal hypotension, nausea & vomiting after spinal anaesthesia, with metaraminol possibly the best.

Patients eligible for emergency laparotomy who do not proceed to surgery are not as well characterised as patients who do proceed to surgery. We studied patients eligible for laparotomy, as defined by National Emergency Laparotomy Audit criteria, from August 2015 to October 2016. We analysed the association of individual variables with survival and two composite scores: P-POSSUM and a general survival model. ⋯ Our study supports the contention that survival beyond 30 postoperative days could be predicted reasonably accurately. Survival in patients who did not have laparotomy was shorter than expected. Emergency laparotomy might have prolonged survival in some patients.

Multicenter Study
Variation in the practice of tracheal intubation in Europe after traumatic brain injury: a prospective cohort study.
Traumatic brain injury patients frequently undergo tracheal intubation. We aimed to assess current intubation practice in Europe and identify variation in practice. We analysed data from patients with traumatic brain injury included in the prospective cohort study collaborative European neurotrauma effectiveness research in traumatic brain injury (CENTER-TBI) in 45 centres in 16 European countries. ⋯ In conclusion, patient and injury characteristics are key drivers of tracheal intubation. Between-centre differences were also substantial. Further studies are needed to improve the evidence base supporting recommendations for tracheal intubation.

Randomized Controlled Trial
The effect of needle tip tracking on procedural time of ultrasound-guided lumbar plexus block: a randomised controlled trial.
Technology that facilitates performance of deep peripheral nerve blocks is of clinical interest. The Onvision™ is a new device for ultrasonographic needle tip tracking that incorporates an ultrasound sensor on the needle tip that is then represented by a green circle on the ultrasound screen. The primary aim of this study was to investigate the effect of needle tip tracking on procedural time in the first human volunteer study. ⋯ No differences were found for any other secondary outcomes. The use of Onvision needle tip tracking did not reduce procedural time for out-of-plane ultrasound-guided lumbar plexus block but did reduce the number of hand movements and path lengths. This may indicate improved needle control but further studies are needed to confirm this finding.

Traditional surgical outcome measures include minor and major complications, hospital length of stay and sometimes longer-term survival. Each of these is important but there needs to be greater emphasis on patient-reported outcome measures. ⋯ A patient's recovery pathway can be mapped through the immediate days or weeks after surgery with documentation of morbidity using the postoperative morbidity survey and/or a quality of recovery score, days alive and at home up to 30 days after surgery and then longer term disability-free survival using the WHO Disability Assessment Schedule 2.0 scale. These can be used to define quality of recovery after surgery.
