Randomized Controlled Trial
The effect of tramadol plus paracetamol on consumption of morphine after coronary artery bypass grafting.
To compare the effects of oral tramadol+paracetamol combination on morphine consumption following coronary artery bypass grafting (CABG) in the patient-controlled analgesia (PCA) protocol. ⋯ Tramadol+paracetamol combination along with PCA morphine improves analgesia and reduces morphine requirement up to 50% after CABG, compared with morphine PCA alone.

Randomized Controlled Trial
Visual/emotional stimuli and treatment with antidepressants alter Numerical Rating Scale score in patients with chronic pain.
To examine the impact of visual stimulation (exciting red and tranquilizing green) on the score of the Numerical Rating Scale (NRS) questionnaire in patients with chronic pain. ⋯ Our findings suggest that visual/emotional stimuli and treatment with antidepressants alter the NRS score in patients with chronic pain.

Comparative Study Clinical Trial
Cardiac output changes with phenylephrine and ephedrine infusions during spinal anesthesia for cesarean section: A randomized, double-blind trial.
Hypotension is a common side effect of spinal anesthesia. Phenylephrine and ephedrine are the two most frequently used vasopressors to treat spinal hypotension during cesarean delivery. In this randomized double-blind study, we aimed to evaluate cardiac output (CO) changes with phenylephrine or ephedrine infusions titrated to maintain baseline systolic blood pressure (bSBP) during spinal anesthesia. ⋯ The maximum increase in CO from the baseline was 12%, in the ephedrine group, and this occurred 20 minutes after spinal injection. Cardiac output fell by more than 17% in the phenylephrine group, maximal at 10 minutes following spinal injection. Despite good systolic blood pressure control and increased cardiac output with ephedrine, administration of ephedrine was associated with significantly more fetal acidosis [Median (Interquartile range, IQR) UApH - phenylephrine = 7.33 (7.31-7.34) and ephedrine = 7.22 (7.16-7.27), P < .05].

Controlled Clinical Trial
Minimum effective fluid volume of colloid to prevent hypotension during caesarean section under spinal anesthesia using a prophylactic phenylephrine infusion: An up-down sequential allocation study.
The aim of this study was to de termine the minimum effective fluid volume (MEFV) of hydroxyethyl starch 130/0.4 (HES) infused in a preload fashion which would prevent hypotension in 50% of parturients undergoing caesarean section. A secondary objective was to measure the hemodynamic effect of fluid loading on the subjects. ⋯ Our study is the first to investigate variable fluid loading volumes in this population. A HES preload of approximatively 700 mL prevented maternal hypotension in 50% of the parturients under the conditions of this study. We suggest that up-down sequential allocation design is a useful tool to compare different fluid loading regimens in this setting.

Case Reports
Case report: Neuromuscular block induced by rocuronium following sugammadex administration.
We present a case in which rocuronium was applied for muscle relaxation following the administration of sugammadex. An emergency surgery under general anesthesia was planned for a 43-year-old male patient due to an L1 vertebral corpus and right tibia-fibula shaft fracture. Anesthesia was induced with fentanyl, propofol and lidocaine. ⋯ The most suitable time for the re-establishment of rocuronium following sugammadex is currently unclear. This case showed that neuromuscular block can be effectively re-induced by rocuronium following the reversal of rocuronium-induced neuromuscular block with sugammadex. In this case, we consider that the ability to effectively reuse normal induction doses of rocuronium is an important clinical observation.
