Hemostatic efficacy of composite polysaccharide powder (starch-chitosan) for emergency bleeding control: An animal model study.

Background: Blood clot formation or hemostasis is vital to minimize blood loss and mitigate the risk of death from severe bleeding. This study investigates the characteristics of a novel hemostatic composite containing chemically modified chitosan and starch for emergency bleeding control. The performance of this novel hemostatic powder was compared with commercially available starch-based (Arista AH) and chitosan-based (Celox) hemostats.

Improvement of Esthetic, Functional, and Social Well-Being After Orthognathic Surgical Intervention: A Sampling of Postsurgical Patients Over a 10-Year Period From 2007 to 2017.

Purpose: The objectives of this study were to evaluate the effect of orthognathic surgery on the long-term quality of life of patients who received this treatment and to delineate the common reasons for dissatisfaction.

Materials And Methods: In this retrospective cohort study, patients who underwent orthognathic surgery were studied. One hundred thirty-two patients who had undergone orthognathic surgery from 2007 to 2017 in the oral and maxillofacial surgery department participated in this study.

Analysis of Facial Symmetry After Zygomatic Bone Fracture Management.

Purpose: The location of the zygomatic bone plays an important role in facial symmetry and esthetics. The aim of this study was to determine and compare the frequency of facial asymmetry in a sample of patients who had undergone treatment of unilateral zygomaticomaxillary complex (ZMC) fractures (study group) and a sample of patients without ZMC fracture (control group).

Materials And Methods: This was a retrospective controlled cross-sectional study.

Effect of Intravenous Ketorolac on Postoperative Pain in Mandibular Fracture Surgery; A Randomized, Double-Blind, Placebo-Controlled Trial.

Objective: To evaluate the effects of intravenous ketorolac on early postoperative pain in patients with mandibular fractures, who underwent surgical repair.

Methods: This prospective, randomized, placebo-controlled clinical trial was conducted in Shahid Rajaei Hospital, affiliated with Shiraz University of Medical Sciences during a 1-year period from 2015 to 2016. We included a total number of 50 patients with traumatic mandibular fractures who underwent surgical repair.

Intravenous Magnesium Sulfate to Deliberate Hypotension and Bleeding after Bimaxillary Orthognathic Surgery; A Randomized Double-blind Controlled Trial.

Statement Of The Problem: The preoperative or intraoperative administration of intravenous magnesium sulfate has been approved as an accepted medication for stabilizing hemodynamic indices during surgeries.

Purpose: Intraoperative blood loss during orthognathic surgery is frequently abundant and sometimes requires blood transfusion. The present trial addressed the efficacy of intravenous magnesium sulfate on deliberating hypotension and bleeding reduction in patients undergoing bimaxillary orthognathic surgery.

The Efficacy of Preoperative Oral Tranexamic Acid on Intraoperative Bleeding During Rhinoplasty.

Background: Perioperative bleeding is a common side effect of rhinoplasty which may impose the blood transfusion to the patients. As a result of risks and cost of blood transfusion, this study is planned to reduce blood loss in these surgeries. Since tranexamic acid (TXA) has been reported to reduce bleeding and subsequent possible need for blood transfusion, the purpose of this study was to evaluate the efficacy of oral TXA on blood loss during rhinoplasty.

Remifentanil, ketamine, and propofol in awake nasotracheal fiberoptic intubation in temporomandibular joint ankylosis surgery.

Background: Nasotracheal intubation of patients with temporomandibular joint (TMJ) ankylosis is a challenge for anesthesiologists. Awake fiberoptic intubation (AFOI) is the safest technique in patients with difficult airway. This study compares 3 different techniques of conscious sedation during AFOI in patients with TMJ ankylosis.

Comparison of the effect of 2 hypotensive anesthetic techniques on early recovery complications after orthognathic surgery.

The aim of this study was to evaluate the recovery complications following the use of 2 anesthetic protocols in orthognathic surgery, namely, propofol with remifentanil and isoflurane with remifentanil. Sixty-two patients with American Society of Anesthesiologists physical status I were selected. All underwent bimaxillary orthognathic surgery.

Efficacy of prophylactic low dose of tranexamic acid in spinal fixation surgery: a randomized clinical trial.

Background: Spinal fixation surgery is potentially associated with significant bleeding, often requiring multiple blood transfusions. Concern for the risks of transfusion-acquired infection and immune modulation effects of allogeneic blood has led to the investigation of various hemostatic agents such as tranexamic acid (TXA). The investigators hypothesized that a prophylactic low dose of TXA would reduce blood loss and transfusion requirements during spinal fixation surgery.

Hemodynamic variation following induction and tracheal intubation--thiopental vs propofol.

Background/aim: Hemodynamic variations are inevitable during induction of anesthetic drugs. The present study, investigates the hemodynamic variations of two different drugs used for induction; Thiopental vs. Propofol.
