The work hours of Norwegian physicians are under scrutiny because of an increased public focus on patient safety. Ample international research indicate harmful effects of doctor fatigue based on studies on physicians working long weeks and on-call shifts of more than 30 consecutive hours. There is a lack of research on effects relevant for short or intermediate length of work weeks and call shifts. This study intended to study cognitive effects of short or intermediate duration in-hospital calls. ⋯ Reaction times were increased after 18 h night calls and non-significant increases in reaction times were apparent after the other on-call shifts. Self reported sleepiness was increased post-call. We were not able to conclude whether executive function or memory was negatively affected post-call.

Observational StudyMinimal impairment in pulmonary function following laparoscopic surgery.
Pulmonary function may be impaired in connection with laparoscopic surgery, especially in the head-down body position, but the clinical importance has not been assessed in detail. The aim of this study was to assess pulmonary function after laparoscopic hysterectomy and laparoscopic cholecystectomy. We hypothesised that arterial oxygenation would be more impaired after hysterectomy performed in the head-down position than after cholecystectomy in the head-up position. ⋯ Minimal impairment in pulmonary gas exchange was found after laparoscopic surgery. Pulmonary shunt was larger after laparoscopic cholecystectomy, but no clinically significant differences in postoperative pulmonary gas exchange or spirometry were found between laparoscopic hysterectomy and laparoscopic cholecystectomy.

Components of pain assessment after laparoscopic donor nephrectomy.
Pain after laparoscopic surgery can be divided into three components: incisional or superficial wound pain, deep intra-abdominal pain and referred shoulder pain. Better understanding and adequate assessment of post-operative pain may be an important clue to the optimisation of recovery after laparoscopic surgery. Therefore, we performed a components of pain assessment after laparoscopic donor nephrectomy. ⋯ The components of pain assessment revealed that pain related to the Pfannenstiel incision and the deep intra-abdominal pain component are the most important determinants of pain after laparoscopic donor nephrectomy. Further improvement of the management of post-operative pain should focus on these components of pain.

Randomized Controlled TrialHeart rate variability dynamics during controlled hypotension with nicardipine, remifentanil and dexmedetomidine.
This study was done to investigate how nicardipine, remifentanil and dexmedetomidine affect the balance of the autonomic nervous system in patients receiving controlled hypotension under general anaesthesia by evaluating heart rate variability indices. ⋯ Remifentanil and dexmedetomidine did not have sympathetic nervous system-stimulating effects during controlled hypotension, while remifentanil seemed to be superior in preserving the overall balance in autonomic nervous system activity. Nicardipine was found to stimulate the sympathetic nervous system, which may be problematic in patients vulnerable to disturbances in the autonomic nervous system.
