Randomized Controlled Trial
Effects of short-term simultaneous infusion of dobutamine and terlipressin in patients with septic shock: the DOBUPRESS study.
Terlipressin bolus infusion may reduce cardiac output and global oxygen supply. The present study was designed to determine whether dobutamine may counterbalance the terlipressin-induced depression in mixed-venous oxygen saturation (Svo) in patients with catecholamine-dependent septic shock. ⋯ In human catecholamine-dependent septic shock, terlipressin (with and without concomitant dobutamine infusion) increases MAP and markedly reduces norepinephrine requirements. Although no adverse events were noticed in the present study, potential benefits of increasing Svo2 after terlipressin bolus infusion need to be weighted against the risk of cardiovascular complications resulting from high-dose dobutamine.

Infusion of hypertonic saline before elective hysterectomy: effects on cytokines and stress hormones.
Infusion of hypertonic saline provides early haemodynamic benefits and may affect the immune system. It is unknown if infusion of hypertonic saline affects plasma cytokines and stress hormones after surgery. ⋯ Infusion of a clinically relevant dose of hypertonic saline before hysterectomy appears to have limited effect on the postoperative concentration of selected plasma cytokines and the hormonal stress-response.

Randomized Controlled Trial
Topical anaesthesia and intravenous cannulation success in paediatric patients: a randomized double-blind trial.
It is not known whether the choice of topical anaesthetic influences the likelihood of successful i.v. cannulation in the paediatric population. The null hypothesis of this study was that no difference exists in the initial success rate of cannulation between two commonly used topical anaesthetics. ⋯ No difference exists in the cannulation success rates between the two anaesthetics. The choice of topical anaesthetic in paediatric cannulation should be based on other factors such as cost, time to anaesthesia, efficacy of the agent, and adverse effect profile.

Randomized Controlled Trial
Ketamine gargle for attenuating postoperative sore throat.
Tracheal intubation is a foremost cause of trauma to the airway mucosa, resulting in postoperative sore throat (POST) with reported incidences of 21-65%. We compared the effectiveness of ketamine gargles with placebo in preventing POST after endotracheal intubation. ⋯ Ketamine gargle significantly reduced the incidence and severity of POST.

Effect of dexmedetomidine premedication on the intraocular pressure changes after succinylcholine and intubation.
Succinylcholine is still recommended for some situations in open globe injuries. However, the use of succinylcholine is associated with an increase in intraocular pressure (IOP). This may be deleterious in open globe injuries. No method has previously been shown to abolish completely this rise in the IOP. We investigated whether dexmedetomidine, an alpha-2 agonist, could attenuate this increase in the IOP after succinylcholine and intubation. ⋯ We conclude that dexmedetomidine could be a beneficial premedication in open globe injuries.
