Randomized Controlled Trial
Evaluation of weight-adjusted doses of palonosetron for prevention of postoperative nausea and vomiting in day care laparoscopic gynaecological surgery: A dose ranging, randomised controlled trial.
Palonosetron 75 mcg is being used for the prevention of postoperative nausea and vomiting. However, weight-adjusted doses in laparoscopic surgery are unevaluated. ⋯ Following laparoscopic gynaecological surgery, intravenous palonosetron has a dose-dependent prophylactic effect against postoperative nausea and vomiting during the first 72 postoperative hours.

Randomized Controlled Trial
Dexmedetomidine added to an opioid-based analgesic regimen for the prevention of postoperative nausea and vomiting in highly susceptible patients: A prospective, randomised controlled trial.
Dexmedetomidine, an α2 adrenergic receptor agonist, has analgesic, sedative and sympatholytic properties, with a lack of respiratory depression. It is licensed only for intensive care sedation. ⋯ Adding dexmedetomidine to a fentanyl-based PCA drug mixture reduces the frequency and severity of acute postoperative nausea in highly susceptible patients.

Observational Study
Assessment of haemostasis in patients with cirrhosis: Relevance of the ROTEM tests?: A prospective, cross-sectional study.
In patients with cirrhosis, decreased rotational thromboelastometry (ROTEM) parameters suggest hypocoagulability secondary to liver dysfunction. However, observed normal or increased thrombin generation suggests preserved haemostasis and/or a procoagulant state. The correlated levels of both coagulation factors and inhibitors also support preserved haemostasis. ⋯ ROTEM indicated hypocoagulability correlated to liver dysfunction. In contrast, the TGT indicated a preserved or even increased coagulation profile (which was supported by the correlation between coagulant factors and inhibitors) and a potential for hypercoagulability inversely correlated to the degree of liver dysfunction. ROTEM may not be appropriate for haemostasis assessment in patients with liver cirrhosis and could lead to the unnecessary transfusion of fresh frozen plasma.
