Objective To evaluate the effects of heparin saline versus normal saline as locking solution for maintaining patency in peripheral venous catheters in Chinese patients. Methods This open-label, randomized controlled study was conducted in two hepatobiliary surgery wards, where patients received identical treatments, at a tertiary referral hospital. Patients were randomly divided into a normal s...

introduction:bleeding is a common concern during functional endoscopic sinus surgery (fess) that can increase the risk of damage to adjacent vital elements by reducing the surgeon’s field of view. this study aimed to explore the efficacy of topical tranexamic acid in reducing intraoperative bleeding. materials and methods:this double-blind, randomized clinical trial was conducted in 60 patients...

gonadotropin-releasing hormone (gnrh) has neuromodulatory roles in central and peripheral nervous systems. the purpose of this study is to evaluate the effect of gnrh analog (buserelin) on peripheral nerve regeneration. forty adult male rats were divided into buserelin-treated, normal saline, sham surgery, and castrated + buserelin groups. the left sciatic nerve was crushed by a fine forceps an...

conclusions both remifentanil and magnesium had favorable outcomes in preventing hr and map elevation after tracheal extubation. however, remifentanil was associated with more rapid regaining of consciousness and reversal of muscular relaxation. results the hr was significantly lower, immediately after extubation and 3, 5, and 10 minutes after extubation, in both magnesium and remifentanil grou...

The bone drilling temperature fields under different cutting parameters and cooling modes were experimental researched by using common twist drill, diamond punching pin, diamond bullet-like grinding head and diamond spherical grinding head. Three cooling modes were applied, namely, natural air cooling, normal saline pouring cooling and normal saline spray cooling. K-thermocouple was used to mea...

OBJECTIVE To assess the effects of intravenous vitamin C administration on the vasomotor responses to intracoronary L-arginine infusion in epicardial coronary arteries. METHODS 28 patients with coronary artery disease and stable angina were enrolled in the study. Eight patients received intracoronary infusions of 150 micromol/min L-arginine before and after intravenous infusion of vitamin C, ...

BACKGROUND Heparin solution is routinely used to maintain the patency of infusion devices. Literature supports the alternative use of normal saline solution for flushing and locking intravenous infusion devices especially for pediatric patients. There is uncertainty regarding safety and efficacy of this policy for intermittent locking of implanted ports. OBJECTIVE This study evaluates efficac...

Normal saline instillation is used by health professionals during the treatment of intubated patients within the intensive care unit, usually to enhance sputum yield. Its use is controversial; detrimental effects have been documented and evidence of any benefit is limited. Some studies have suggested routine use be discontinued. This study investigates the use of normal saline instillation in t...
