Randomized Controlled Trial Comparative Study
Intranasal lidocaine plus naphazoline nitrate improves surgical conditions and perioperative analgesia in septorhinoplasty surgery.
Septorhinoplasty is a traumatic procedure that is associated with epistaxis and postoperative pain. The primary objective of this randomized double-blind controlled trial was to determine whether intranasal 5% lidocaine plus naphazoline decreases postoperative pain and lessens the use of rescue analgesics. ⋯ Intranasal lidocaine plus naphazoline is a simple and efficient technique for decreasing intra- and postoperative pain and for lessening rescue analgesic requirements in the postoperative period after septorhinoplasty. Toxic plasma concentrations of lidocaine were not reached.

To review and discuss the epidemiology, contributing factors, and approach to clinical management of disorders of sodium and water balance in hospitalized patients. ⋯ In hospitalized patients, hyponatremia and hypernatremia are often iatrogenic and may contribute to serious morbidity and increased risk of death. These disorders require timely recognition and can often be reversed with appropriate intervention and treatment of underlying predisposing factors.

Controlled Clinical Trial
Ultrasound-guided block of the brachial plexus at the humeral canal.
Conduction block of the brachial plexus block at the humeral canal, as described by Dupre, has certain clinical indications. The aim of this preliminary study was to assess the feasibility of this technique under ultrasound guidance. ⋯ We describe an approach to, and the feasibility of ultrasound-guided block of the brachial plexus at the humeral canal. Further study will be required to establish the effectiveness and the safety of this technique.

Comparative Study
The protective effects of emulsified isoflurane on myocardial ischemia and reperfusion injury in rats.
Pretreatment with volatile anesthetics has been demonstrated to exert cardioprotective effects. The purpose of this study was to examine the effect of emulsified isoflurane, a new formulation of isoflurane in lipid emulsion, administered intravenously in an ischemia and reperfusion model of myocardial injury. ⋯ These data support a cardioprotective effect of intravenous emulsified isoflurane against myocardial ischemia and reperfusion injury, which are mediated, at least in part, by the inhibition of apoptosis and cell damage.
