Randomized Controlled Trial
Intrapartum epidural fixation methods: a randomised controlled trial of three different epidural catheter securement devices.
This randomised controlled trial investigated the efficacy of Epi-Fix(™) , LockIt Plus(®) and Tegaderm(™) as fixation devices for intrapartum epidural catheters. One hundred and sixty-five women requesting intrapartum epidural analgesia were randomised to receive different fixation devices to secure their epidural catheter. The amount of epidural catheter migration (measured to the nearest 0.5 cm) was analysed for three devices: Epi-Fix (n = 55); LockIt Plus (n = 54); and Tegaderm dressing (n = 51). ⋯ Thirty-eight (69.1%) epidural catheters secured with Epi-Fix migrated < 2.0 cm, compared with 49 (90.7%) with LockIt Plus and 40 (78.4%) with Tegaderm. Sixteen epidural catheters required resiting due to failure of analgesia of which 12 (75.0%) occurred in patients with epidural catheters that had migrated ≥ 2.0 cm. This study shows that intrapartum epidural catheters secured with the LockIt Plus device exhibit less catheter migration compared with fixation with Epi-Fix and Tegaderm.

Letter Practice Guideline
The measurement of adult blood pressure and management of hypertension before elective surgery: Joint Guidelines from the Association of Anaesthetists of Great Britain and Ireland and the British Hypertension Society.
This guideline aims to ensure that patients admitted to hospital for elective surgery are known to have blood pressures below 160 mmHg systolic and 100 mmHg diastolic in primary care. The objective for primary care is to fulfil this criterion before referral to secondary care for elective surgery. ⋯ Secondary care should not attempt to diagnose hypertension in patients who are normotensive in primary care. Patients who present to pre-operative assessment clinics without documented primary care blood pressures should proceed to elective surgery if clinic blood pressures are below 180 mmHg systolic and 110 mmHg diastolic.
