Randomized Controlled Trial Clinical TrialA risk score to predict the probability of postoperative vomiting in adults.
The aim of this study was to identify factors most relevant for postoperative vomiting (PV) and to develop a risk score to predict the probability of PV. ⋯ The data suggest that the probability of PV following ENT surgery under inhalational anaesthesia with low-dose opioids can be predicted by a score mainly based upon patient-related risk factors.

Comparative StudyThe discriminating power of a risk score for postoperative vomiting in adults undergoing various types of surgery.
Recently, we have demonstrated that the probability of postoperative vomiting (PV) following ENT surgery with inhalational anaesthetics can be predicted using a risk score. This score is based on gender, age, smoking status, history of motion sickness or postoperative nausea and vomiting and the duration of anaesthesia. Therefore, it is of interest whether this score is also accurate in predicting PV in patients undergoing different types of surgery. ⋯ Score I was accurate in predicting PV in patients after most types of surgery with volatile anaesthetics, which suggests that this score might be useful for other centres as well.

Prognostic importance of automated ST-segment monitoring after coronary artery bypass graft surgery.
Automated ST-segment monitors are widely used in cardiac surgery units. The purpose of this study was to determine if cardiac morbidity and mortality, after CABG surgery, are predicted by ECG ST-segment changes on automated monitors. ⋯ Automated ST analysis is a non-invasive, sensitive and very easy-to-use monitoring system to screen patients who may develop myocardial ischemia and cardiac complications after CABG surgery.

Randomized Controlled Trial Comparative Study Clinical TrialComparison of analgesic efficacy of oxycodone and morphine in postoperative intravenous patient-controlled analgesia.
Morphine has been the standard opioid in patient-controlled analgesia (PCA). Oxycodone, the analgesic potency of which in i.v. administration has been suggested to be slightly greater than that of morphine, has not yet been studied for its efficacy in PCA. ⋯ The same dose of intravenous oxycodone and morphine administered by PCA pump was needed for immediate postoperative analgesia. The two drugs appear to be equipotent.

Randomized Controlled Trial Comparative Study Clinical TrialPercutaneous dilatational tracheostomy versus conventional surgical tracheostomy. A clinical randomised study.
As no clinical randomised studies have previously been performed comparing complications with the Ciaglia Percutaneous Dilatational Tracheostomy Introducer Set (PDT) and conventional surgical tracheostomy (TR), we designed a study with the aim of comparing the efficacy and safety of the two techniques. ⋯ Our results indicate that the percutaneous dilatational tracheostomy technique performed with the Ciaglia Introducer Set is effective, safe and superior to conventional surgical tracheostomy as immediate complications as well as complications with the tracheostomy tube in situ are fewer and of less severity.
