Randomized Controlled Trial
Effect of preoperative fever-range whole-body hyperthermia on immunological markers in patients undergoing colorectal cancer surgery.
Previous studies have demonstrated beneficial immunological effects of fever-range whole-body hyperthermia (FR-WBH) as an adjunct to non-surgical cancer therapy. We conducted a study of preoperative FR-WBH in patients undergoing colorectal cancer surgery to evaluate perioperative, hyperthermia-induced immunomodulation. ⋯ The immune system to react to surgical stress, as measured by a panel of laboratory indicators, might be improved by preoperative FR-WBH.

Airway problems continue to occur in intensive care setting. Management strategies, staffing, and availability of equipment can all have an influence. ⋯ There remains room for improvement in airway management strategies and resources in ICUs in the UK.

Target controlled infusion (TCI) with sufentanil is usually performed using the Gepts model, which was derived from patients undergoing general surgery. It is, however, known that pharmacokinetics of sufentanil can be changed during cardiopulmonary bypass (CPB). We tested whether TCI during coronary artery bypass surgery with CPB produces constant total, unbound sufentanil concentration-time course or both. ⋯ Neither total nor unbound sufentanil concentrations remained constant when performing a TCI with the Gepts model in coronary artery bypass surgery with CPB. A pharmacokinetic model derived from patients undergoing cardiac surgery with CPB might improve the performance of TCI in this population.

/st> In assessing a patient's risk for postoperative nausea and vomiting (PONV), it is important to know which risk factors are independent predictors, and which factors are not relevant for predicting PONV. ⋯ /st> The most reliable independent predictors of PONV were female gender, history of PONV or motion sickness, non-smoker, younger age, duration of anaesthesia with volatile anaesthetics, and postoperative opioids. There is no or insufficient evidence for a number of commonly held factors, such as preoperative fasting, menstrual cycle, and surgery type, and using these factors may be counterproductive in assessing a patient's risk for PONV.
