Randomized Controlled Trial
Effects of dobutamine and phenylephrine on cerebral perfusion in patients undergoing cerebral bypass surgery: a randomised crossover trial.
Patients undergoing cerebral bypass surgery are prone to cerebral hypoperfusion. Currently, arterial blood pressure is often increased with vasopressors to prevent cerebral ischaemia. However, this might cause vasoconstriction of the graft and cerebral vasculature and decrease perfusion. We hypothesised that cardiac output, rather than arterial blood pressure, is essential for adequate perfusion and aimed to determine whether dobutamine administration resulted in greater graft perfusion than phenylephrine administration. ⋯ Netherlands Trial Register, NL7077 (https://www.trialregister.nl/trial/7077).

Pragmatic Clinical Trial
Norepinephrine or phenylephrine during spinal anaesthesia for Caesarean delivery: a randomised double-blind pragmatic non-inferiority study of neonatal outcome.
Norepinephrine is an effective vasopressor during spinal anaesthesia for Caesarean delivery. However, before it can be fully recommended, possible adverse effects on neonatal outcome should be excluded. We aimed to test the hypothesis that umbilical arterial cord pH is at least as good (non-inferior) when norepinephrine is used compared with phenylephrine for treatment of hypotension. ⋯ ChiCTR-IPR-15006235.

Observational Study
Validation and clinical utility of the Korean version of the Quality of Recovery-15 with enhanced recovery after surgery: a prospective observational cohort study.
The 15-item Quality of Recovery (QoR-15) scale is a validated patient-reported outcome questionnaire that measures the quality of postoperative recovery. This study aimed to validate a translated Korean version of QoR-15 (QoR-15K) in a broad range of surgical patients. ⋯ NCT04169087.
