Randomized Controlled Trial Comparative Study
Remifentanil for labour analgesia: a double-blinded, randomised controlled trial of maternal and neonatal effects of patient-controlled analgesia versus continuous infusion.
Remifentanil patient controlled analgesia during labour is more effective and results in less remifentanil consumed than does continuous infusion.

Randomized Controlled Trial
A double-blinded randomised controlled study of the value of sequential intravenous and oral magnesium therapy in patients with chronic low back pain with a neuropathic component.
Persistent mechanical irritation of the nerve root sets up a series of events mediating sensitisation of the dorsal roots and dorsal horns in the spinal cord. Current evidence supports the role of magnesium in blocking central sensitisation through its effect on N-methyl-d-aspartate receptors. We studied the role of sequential intravenous and oral magnesium infusion in patients with chronic low back pain with a neuropathic component. ⋯ The reduction in pain intensity was accompanied by significant improvement in lumbar spine range of motion during the follow-up period. The mean (SD) values of flexion, extension and lateral flexion movements before treatment and at 6-month follow up were 22.2 (8.4) vs 34.7 (11.5) (p = 0.018), 11.8 (3.4) vs 16.9 (3.5) (p = 0.039), 11.4 (3.6) vs 17.2 (4.4) (p = 0.035), respectively. Our findings show that a 2-week intravenous magnesium infusion followed by 4 weeks of oral magnesium supplementation can reduce pain intensity and improve lumbar spine mobility during a 6-month period in patients with refractory chronic low back pain with a neuropathic component.

Case Reports
Cardiac arrest in an obstetric patient using remifentanil patient-controlled analgesia.
This case report describes the management of a patient, diagnosed with an intrauterine death at 31 weeks' gestation, who suffered a cardiorespiratory arrest during her induced labour while using a remifentanil PCA. She made a full recovery from resuscitation which included a peri-mortem caesarean section.

Practice Guideline
Immediate post-anaesthesia recovery 2013: Association of Anaesthetists of Great Britain and Ireland.
1. After general, epidural or spinal anaesthesia, all patients should be recovered in a specially designated area (henceforth 'post-anaesthesia care unit', PACU) that complies with the standards and recommendations described in this document. 2. The anaesthetist must formally hand over the care of a patient to an appropriately trained and registered PACU practitioner. 3. ⋯ When critically ill patients are managed in a PACU because of bed shortages, the primary responsibility for the patient lies with the hospital's critical care team. The standard of nursing and medical care should be equal to that in the hospital's critical care units. Audit and critical incident reporting systems should be in place in all PACUs.
