Randomized Controlled Trial Comparative Study
Ondansetron added to lidocaine for intravenous regional anaesthesia.
The aim of this study was to evaluate the effect of ondansetron when added to lidocaine for intravenous regional anaesthesia (IVRA). ⋯ Addition of ondansetron to lidocaine may improve the quality of IVRA and prolong postoperative analgesia in patients undergoing hand surgery.

Different minimally invasive haemodynamic monitoring techniques are commercially available today and in the recent years they have proved adequate in replacing the pulmonary artery catheter under certain clinical conditions. Moreover, several of these techniques provide additional new parameters primarily related to preload assessment. Therefore, in order to be used in daily clinical practice, the diversity of minimally invasive haemodynamic monitoring requires knowledge of the different techniques, the different parameters provided by the devices and their clinical validity. The aim of the present article is to review the most widely used minimally invasive cardiac output monitoring techniques; emphasize the new parameters available for preload assessment;and propose a modular stepwise monitoring concept.

Randomized Controlled Trial Comparative Study
Prophylactic amiodarone versus lidocaine for prevention of reperfusion ventricular fibrillation after release of aortic cross-clamp.
Ventricular fibrillation is common after aortic cross-clamp release in patients undergoing open-heart surgeries. The aim of the study was to evaluate the efficacy of the prophylactic administration of 150 mg amiodarone by way of the pump 2 min before release of aortic cross-clamp in preventing ventricular fibrillation. ⋯ The present study showed no difference between amiodarone (150 mg) and placebo in preventing ventricular fibrillation after release of aortic cross-clamp. In addition, the use of lidocaine was able to reduce the incidence of ventricular fibrillation as compared with both amiodarone and placebo.

Randomized Controlled Trial Comparative Study
Comparison of the laryngeal mask airway Supreme and laryngeal mask airway Classic in adults.
The laryngeal mask airway (LMA) is an important airway device that was developed in 1983. From the first classic LMA models up to now, LMA models have been developed that are easily and quickly inserted, provide ventilation at higher airway pressures, have lower cuff pressure, a reduced risk of gastric aspiration and cause fewer stress responses. We aimed to compare the LMA Classic with the LMA Supreme in assessing the success rate and time for insertion, number of attempts and leak pressure. ⋯ The LMA Supreme is superior to the LMA Classic because of its ease of insertion with low cuff pressure and high oropharyngeal leakage pressure.

Randomized Controlled Trial Comparative Study
Comparison of analgesic efficacy between bilateral superficial and combined (superficial and deep) cervical plexus block administered before thyroid surgery.
To evaluate the analgesic efficacy of bilateral superficial cervical plexus block and combined superficial and deep cervical plexus block for incision pain, headache and posterior neck pain after thyroidectomy. ⋯ Superficial cervical plexus block is a more effective technique than combined superficial and deep cervical plexus block to reduce the pain during and immediately after thyroidectomy.
