Abstract :
[en] Autonomic responses, mood and psychological coping were assessed in two groups of orthopaedic patients during hospitalisation for major or minor surgery. Eight patients admitted for total hip replacement and seven patients undergoing knee arthroscopy were seen daily for two days before surgery until discharged from hospital. Mood and coping questionnaires were administered on each session, while pain, heart rate, blood pressure, skin conductance level, palmar sweat prints and forearm EMG were also recorded. Heart rate increased from pre- to post-operative assessments, while skin conductance and palmar sweating fell to low levels on the days immediately following surgery, returning to basal values only after several days. Self ratings of anxiety, fatigue, depression and pain were highest on the immediate post-operative days. Patients utilised the coping factors Rational Cognition and Behavioural Action to the greatest extent, but ratings on coping factors fluctuated little over the study period. The interrelations between these measures and possible explanations of the results are discussed.
