Anaesthesia and intensive care

The current trend to treat hypotension in critically ill patients is to place a greater emphasis on inotropic support and less on fluid resuscitation in order to limit the potential harm from fluid overload. This combination may trigger left ventricular outflow tract obstruction (LVOTO) in susceptible patients. Although LVOTO is classically described in patients with hypertrophic cardiomyopathy it has been reported in other conditions including septic shock, apical ballooning syndrome, myocardial infarction, respiratory failure, and post valvular surgery. ⋯ Dynamic LVOTO should be considered in any hypotensive intensive care patient. Echocardiography is perhaps the best tool to assess LVOTO and its underlying pathophysiology in the critically ill. Detection of LVOTO is a relatively simple task using a combination of two-dimensional, M-mode and spectral Doppler imaging by an operator alert to the possible diagnosis.

This study was designed to investigate levels of stress, anxiety or depression and to identify factors compounding or relieving stress in anaesthesia trainees within the Australian and New Zealand College of Anaesthetists (ANZCA) training scheme. An electronic survey was sent to 999 randomly selected trainees and 428 responses were received. In addition to demographics, psychological wellbeing was assessed using the Kessler Psychological Distress Scale (K10) and questions were asked about depression and anxiety, exacerbating factors, personal healthcare and strategies used to manage stress. ⋯ Two stressors previously not identified in similar studies were concern about job prospects in 71% of respondents and workplace-based assessments in 51%. This survey demonstrates significant psychological impairment and poor personal healthcare amongst many trainees. Education, careful continuing assessment of trainees' welfare and a review of current support and remedial measures may be required.
