The association between erector spinae plane block timing and reduced rib fracture related respiratory complications: A cohort study.

Study Objective: Is erector spinae plane (ESP) catheter insertion within 24 h of hospital admission for rib fractures associated with a lower incidence of respiratory complications compared to those having an ESP within 48 h or after 48 h of admission.

Design: Retrospective cohort study.

Setting: Hospital.

Management of surgical patients on opioid replacement therapy: An audit of current practice.

Patients on opioid replacement therapy hospitalised with acute pain represent a clinical challenge and have poorer perioperative outcomes. There is limited evidence relating to acute pain management of this complex cohort. The primary objectives of this retrospective audit was to establish the number of patients who are admitted on opioid replacement therapy with an acute pain condition under surgical services and evaluate the management of these patients to determine consistency of pain management practices.

Cerebral microcirculation during mild head injury after a contusion and acceleration experimental model in sheep.

Background: Cerebral microcirculation after head injury is heterogeneous and temporally variable. Regions at risk of infarction such as peri-contusional areas are vulnerable to anaemia. However, direct quantification of the cerebral microcirculation is clinically not feasible.
