Prediction of postoperative pain from assessment of pain induced by venous cannulation and propofol infusion.
Postoperative pain may lead to delayed mobilization, persisting pain, and psychosocial distress. There are no simple and reliable techniques for prediction of postoperative pain. This study was designed to evaluate if pain induced by venous cannulation or propofol injection can be used to predict postoperative pain. ⋯ Pain intensity associated with venous cannulation and propofol infusion can easily be evaluated at bedside before surgery without specific equipment or training. Patients scoring > 2.0 VAS units on venous cannulation were found to have 3.4 times higher risk of postoperative pain after laparoscopic cholecystectomy. Low pain intensity associated with venous cannulation and propofol infusion indicate lower risk of postoperative pain.

A validation of the pain interference index in adults with long-standing pain.
Chronic pain is a major health problem and more knowledge is needed regarding the interference of pain on behaviors in different life domains. Clinically useful and statistically sound pain interference measures are highly important. Studies on youths have shown that the Pain Interference Index (PII) is a reliable and valid instrument that is sensitive to change following behavioral treatment. This measure may also have utility for adults, but no study has so far evaluated the statistical properties of the PII for long-standing pain in adults. ⋯ The PII is a brief questionnaire with reliable and valid statistical properties to assess pain interference in adults. Other studies support the reliability and validity of PII for use with youths, and now the PII can be used to analyze the influence of pain on behaviors across age groups. Potentially, the PII can also be used as an outcome measure in clinical trials.

Intraoperative factors associated with delayed recovery of liver function after hepatectomy: analysis of 1969 living donors.
The safety of healthy living donors who are undergoing hepatic resection is a primary concern. We aimed to identify intraoperative anaesthetic and surgical factors associated with delayed recovery of liver function after hepatectomy in living donors. ⋯ Anaesthesia with sevoflurane was an independent factor in predicting delayed recovery of hepatic function after donor hepatectomy. Although synthetic colloid may be associated with delayed recovery of hepatic function after donor hepatectomy, further study is required. These results can provide useful information on perioperative management of living liver donors.

Impact of oxygen sources on performance of the Ventrain(®) ventilation device in an in vitro set-up.
The Ventrain(®) (Dolphys Medical, Eindhoven, The Netherlands) is a disposable handheld ventilation device allowing active inspiration and expiration through a transtracheal catheter. This study investigated Ventrain(®) 's performance when used with different clinical oxygen sources in an in vitro set-up. ⋯ The oxygen sources resulted in clinically different IP, flows, and VT delivered by the Ventrain(®) at given gas flow rates. This needs to be considered in a clinical emergency situation. Integrating an adjustable pressure valve into Ventrain(®) to allow regulation of the lowest necessary IP would make its use safer.
