Postoperative atrial fibrillation (AF) occurs in 30-40% of patients after cardiac surgery. Identification of recurrent postoperative AF is required to initiate evidence-based management to reduce the risk of subsequent stroke. However, as AF is often asymptomatic, recurrences may not be detected after discharge. This study determines feasibility and impact of a self-surveillance programme to identify recurrence of postoperative AF in the month of posthospital discharge. ⋯ Primary ethics approval was received on 25 February 2014 from Northern Sydney Local Health District Human Resource Ethics Committee, and on 17 July 2014 from North Shore Private Hospital Ethics Committee. Results will be disseminated via forums including, but not limited to, peer-reviewed publications and presentation at national and international conferences.

Randomized Controlled Trial
Subcutaneous Injection of Diclofenac for the Treatment of Pain Following Minor Orthopedic Surgery (DIRECT study): A Randomized Trial.
Parenteral diclofenac is frequently used for analgesia following minor orthopedic interventions. Currently available diclofenac formulations are for intramuscular (IM) or intravenous injection. A new 1 mL volume formulation of diclofenac containing hydroxypropyl-β-cyclodextrin (HPβCD) allows both SC and IM administration. The objective of this open-label, randomized, parallel group, active-controlled study was to assess the safety and efficacy of 75 mg diclofenac HPβCD, administered SC or IM, compared with IM Voltaren® 75 mg in inpatients undergoing minor orthopedic surgeries with moderate-to-severe postoperative pain. ⋯ Overall, the study results indicate that safety and efficacy were similar irrespective of the diclofenac formulation used; thus, the new SC diclofenac HPβCD has an acceptable tolerability profile and may be considered a valid alternative to IM-delivered diclofenac formulations.

Randomized Controlled Trial Comparative StudyNicardipine Is Superior to Esmolol for the Management of Postcraniotomy Emergence Hypertension: A Randomized Open-Label Study.
Emergence hypertension after craniotomy is a well-documented phenomenon for which natural history is poorly understood. Most clinicians attribute this phenomenon to an acute and transient increase in catecholamine release, but other mechanisms such as neurogenic hypertension or activation of the renin-angiotensin-aldosterone system have also been proposed. In this open-label study, we compared the monotherapeutic antihypertensive efficacy of the 2 most titratable drugs used to treat postcraniotomy emergence hypertension: nicardipine and esmolol. We also investigated the effect of preoperative hypertension on postcraniotomy hypertension and the natural history of postcraniotomy hypertension in the early postoperative period. ⋯ Nicardipine is superior to esmolol for the treatment of postcraniotomy emergence hypertension. This type of hypertension is thought to be a transient phenomenon not solely related to sympathetic activation and catecholamine surge but also possibly encompassing other physiologic factors. For treating postcraniotomy emergence hypertension, nicardipine is a relatively effective sole drug, whereas if esmolol is used, rescue antihypertensive medications should be readily available.
