Preparation and Properties of Thin-Film Composite Forward Osmosis Membranes Supported by Cellulose Triacetate Porous Substrate via a Nonsolvent-Thermally Induced Phase Separation Process.

A porous substrate plays an important role in constructing a thin-film composite forward osmosis (TFC-FO) membrane. To date, the morphology and performance of TFC-FO membranes are greatly limited by porous substrates, which are commonly fabricated by non-solvent induced phase separation (NIPS) or thermally induced phase separation (TIPS) processes. Herein, a novel TFC-FO membrane has been successfully fabricated by using cellulose triacetate (CTA) porous substrates, which are prepared using a nonsolvent-thermally induced phase separation (N-TIPS) process.

The effect of epidural lidocaine administration on sedation of propofol general anesthesia: a randomized trial.

Study Objective: To examine the influence of epidural and intravenous (IV) lidocaine, and height of the epidural sensory block, on the dose of propofol required for induction of general anesthesia.

Design: Randomized controlled study.

Setting: University hospital.

[Anesthetic management of Stanford type A aortic dissection operation].

Objective: To explore the anesthetic management experiences of patients with Stanford A aortic dissection undergoing surgical treatment through moderate or deep hypothermia circulatory arrest (DHCA).

Methods: From June 2008 to December 2011, a total of 77 patients undergoing surgical treatment of Stanford A aortic dissection was recruited.

Results: Cardiopulmonary bypass (CPB) was established under general anesthesia in all patients.

Low doses of esmolol and phenylephrine act as diuretics during intravenous anesthesia.

Introduction: The renal clearance of infused crystalloid fluid is very low during anaesthesia and surgery, but experiments in conscious sheep indicate that the renal fluid clearance might approach a normal rate when the adrenergic balance is modified.

Methods: Sixty females (mean age, 32 years) undergoing laparoscopic gynecological surgery were randomized to control group and received only the conventional anesthetic drugs and 20 ml/kg of lactated Ringer's over 30 mins. The others were also given an infusion of 50 μg/kg/min of esmolol (beta1-receptor blocker) or 0.
