Multicenter Study
National survey of College Tutors in the UK regarding training in medical education.
College Tutors are responsible for the organization of training and should possess the pre-requisite knowledge and skills to facilitate this. ⋯ This survey highlights that training in medical education for College Tutors is inadequate. It is the responsibility of the Colleges and the Postgraduate Deans to ensure College Tutors are supported appropriately to develop the knowledge and skills required for the role.

Randomized Controlled Trial
Transcutaneous electrical nerve stimulation at the PC-5 and PC-6 acupoints reduced the severity of hypotension after spinal anaesthesia in patients undergoing Caesarean section.
Despite prophylactic measures, hypotension remains a common side-effect of spinal anaesthesia for parturients. Electroacupuncture at the Neiguan (PC-6) and Jianshi (PC-5) points influences haemodynamics. We thus hypothesized that transcutaneous electrical nerve stimulation (TENS) at traditionally used acupuncture points would reduce the severity of hypotension after spinal anaesthesia in patients undergoing Caesarean section. ⋯ TENS on the traditional acupuncture points reduced the severity and incidence of hypotension after spinal anaesthesia in parturients.

It is believed that the severely disturbed night-time sleep architecture after surgery is associated with increased cardiovascular morbidity with rebound of rapid eye movement (REM). The daytime sleep pattern of patients after major general surgery has not been investigated before. We decided to study the circadian distribution of sleep phases before and after surgery. ⋯ Patients have significantly increased REM sleep, LS, and reduced time awake during the daytime period after surgery compared with before surgery. Disturbances in the circadian regulation of the sleep-wake cycle may be involved in the development of postoperative sleep disturbances.

The purpose of this study was to evaluate the agreement of cardiac output measurements obtained by electrical velocimetry (CO(EV)) and those that derived from the direct Fick-oxygen principle (CO(F)) in infants and children with congenital heart defects. ⋯ CO(EV) demonstrates acceptable agreement with data derived from CO(F) in infants and children with congenital heart disease. The new technique is simple, completely non-invasive, and provides beat-to-beat estimation of CO.
